They can be adapted to carry a wide range of operating accessories from backhoes to dri,lls to cranc~s to seismic vibratois to transmission line tens1oners and pullers. We've designed products for a wide range of industrial needs from firefighters to brush cutters to floating personnel carriers. ·~ IJ~ D I I I I I I j. I " I ' Terra-Flex designs represent the culm1nation of two decades of continuous evolution in all terrain vehicle technology. Our large, experienced engineering group keeps us in the .forefront in the development of innovative products to satisfy all terrain transportation requirements around the world. We've recently designed, manufactured, and proven the TF900, the world's largest, commercially available tracked transport-the most advanced product of its kind. Through utiiJzation of walking beam suspension, 60 inch tracks, and full articulation between front and rear tracks, the "900" provides unsurpassed mobility at payloads up to 50 tons. Articulated Roll Joint Terra-Flex's wheeled product Hne features a unique articulated roll joint which significantly reduces twisting forces on the frame whiie traversing irregular terrain-without affecting overall stability. Our in-depth understanding of the operational effects of the relationship between vehicle width and contact track length has allowed us to pioneer the design of two-track vehicles with payloads in excess of 20 tons. Our "360" (a 20 ton capacity two-tracked carrier) has a proven record of dependability and performance while providing substantially more useful deck space and a significantly smaller turning radius within shorter overall dimensions than its four tracked equivalents. Walking Beam Suspension Where terrain conditions require maximum load distribution, we lead the industry in the use of walking beam suspen~!on, expecially in the area of heavy tracked vehicles. The walking beam principle enables pairs of wheels to oscillate independently of each other and maintain equal tire loading on the tracks. Torsion Spring When loads consist of personnel or fragile, sophisticated equipment, we provide the required speed and smoothness of ride through the use of Terra-Flex's proven torsion spring suspension system.

Duncan: October 19, 1982 Furt.her· to our recent telephone conv8rsation and our discussion regarding drilling ~quipm~nt and operation on the above mentioned project, we are pleased to confirm the following points: 1. All equipment used on ~ project of this type} considering ter- rain difficulties and winter concfitions, should be in f·irst class c o n d i t i o n , p r e f e r a b 1 y n e \'1 ·0 A 1 1 e q u i p me n t s h o u 1 d b e f u 1 1 y t e s t e d before transported to site. All operators should have extensive experience on this type of equipment, and in particular, given your specifications, deep hole experience~ if possible. 2 • A s y o u k n ow , t h e r e· a r e t w o s t y 1 e s o f h a m m e r d r i 1 1 p i p e c u r - rently being used by various drilling contractors. The old style has restricted air passages in the annulus, which 1 imits depth capacity. For this reason we would recommend that only new style, floating inner tube, greater air passage capacity be used on this project. 3. Given climatic conditions that will prevail, we would further recommend that the r i g be 11 c 1 o sed i n" w i t h t a r p a u 1 i n s o r s om e other cover. This relativP.ly inexpensive operation would add greatly to the efficiency and safety of· the drilling programs. r-----------~ --~-------~-~·"·' ·---~-~----~r -I I .. I . ~ ~ f I ~ . ~ ~ I !

Gauges for hydraulic oil pressure~ water and air pressure ~le.ai ly visible for inspection. The controls are arranged in a logical ;ence so that each drilling procedure can be carried out smoothly. il I I C4CW! - Deck Features Angle and Vertical Drilling. The drill is designed to drill holes from vertical to 45 ° off vertical. The lateral travel of the mast on the deck and the mast slide, allows the hole to be positioned within working dis- tance of the operator. When pulling drill pipe, the breakout or puller reacts against the ground and relief valves and the mast slide cylinders eliminates loading the mast. Drill Compressor. A Sullair Rotary Screw Compre,ssor provides a regular flow of air on de- mand. Air is supplied at the rate of 750 CFM@ 125 PSI,(optional250 PSI) cooled and lubricated bv an independent oil supply. Power for the compressor is provided by the carrier engine, via the transfer case. Additional Deck Fe The deck and contr system·· is readily system has bee removable· sections. All hydraulic lines, tubes have been sta pie replacement. T the deck allow for inspection of all equipped with a night operations. --- . . -~;: .~:"' ·~ :-~~ : ~. ~:: :~.;· :-~:)-.1~ -~~.· .... 1 .......... _ ..... ~-0 ',. ·~:-~,· --r---• I I I I ... _ I' •' . :. .. .•. ... _ ,. ... ·!~"'-~ ....... • . .. _-~. -~· ~ ... . . . -· .. ~ .. . ;... .:. . . . .. -.. ;-. .. ·"!,.~ . .. ·:st. _t..._,·. +~t~f{eli;I ·i:; ;::~:·~~~~:!:: :;.~~·:::~·?/ ~: • ~\-··:· ..

( ~; " (· SECTION I HISTORY OF THE "BECKER HAMHER DRILLn In the late 1950's a large seismic drilling contract was . . . obtained by Becker Drills Ltd. in northern, Alberta, Canada. . - The conditions were found to be almost totally gravel and cobbles and conventional drilling practices were not able to keep the hole open for loading the explosive charges. It was at this time that the situation forced the development of the "Becker Hammer Drill." The concept was the us.e of a double wall drive pipe under impact by a conventional pi!e driver, with air as an assist for cleaning the hole. It was several years and a good quantity of bent and broken . . drill pipe later, before the system and method could operate reliably and feasibly. Becker then began to receive inquiries from throughout the . world. Over the first six or seven years, twenty two (22) rigs were sold. Many applications of this method have been employed as well as a few variations which will be discussed later and explained in more detail. The Becker Drill is still m~nufactured in Calgary, Alberta, with Becker Drills Inc. as the prime user of the system. Most of the many rigs sold over the years are owned by operators. Becker Drills Inc. is still the major contractor using this system in North America and the free world. "" -.... ,.l.' .. ' c:fA#*:ax:aw-= 1 < .. r r '.1. l . . i Jl [' SECTION II THE BECKER HAMMER METHOD The most noteworthy characteristic: of the Becker Hammer Drill is the method by which sand, gravel and boulder formations can be penetrated rapidly and efficiently, giving immediate, accurate analysis of the formation encountered. . . - A double wa~i drive pipe is driven by a diesel operated pile hammer, while air or water, under pressure, is forced down the ' . annulus of the drive pipe. The material cut by the drill bit is rapidly transported to the surface through the inside pipe . - by the drilling fluid. The discharged materials can be accumulated -. in suitable containers as they emerge from a cyclone and samples bagged at specific intervals for analysis of the drilled formation. . . As the center of the drive pipe is always clear and the bit remains on the bottom of the hole, Pentrometer, Shelby 1 ~r Split-Spoon tests can be taken at any desired interval. Upon reaching bedrock, a hydraulic driven rotary attachment can be swung into position, and the drive pipe then acts as the overburden casing and conven- tional drilling methods may proceed for the coring of bedrock. : . Chip sampling with air and tr-icone bits or down-the-hole hammer . . bits can be achieved very economically as the difficulty of penetrating the overburden has been overcome. . . , Designed for drilling in gravel, sand, and boulder formations, th!s rugged unit achieves penetration rates up to 100 feet per hour and provides a continuous sample. For sampling, close to 100% recovery can be achfeved (See Figure 1). CHARACTERISTICS The significant features of the Becker method are: a. The highly efficient method of driving the casing with a diesel pile hammer. b. The double walled casing with a large hollow center. Due to this large center opening, material up to three inch size can enter the bit, where it is airlifted instantly and effortlessly. The conventional process of grinding the cuttings down to dust size is eliminated. 2 .r ·f:. ·.~ r l·.j .. . ~., ' J . J ~ Ji' J '-"" ; J: ' ' c. Drilling the hole and casing it, is one-and-the-same operation. There is no duplication of efforts by first drilling the hole, then casing it, then cleaning out the casing. HOW IT 'tvORKS The Becker drill is a self-contained unit with all required components mounted on a tandem axle truck. The diesel hammer, . . . delivering 95 blows per minute, at 8,000 foot-pounds per blow is mounted on a standard mast (Figure 2)~ A 750 cfm compressor at 125 p~soi. and a 130 gpm pump are driven from a transfer case. The hydraulics operate all functions such as: leveling truck, raising mast, lowering and raising of hammerJ handling of casing, ~tc. On completion of the hole, the casing is withdrawn by a puller system comprising two 50 ton hydraulic cylinders operating tapered slips that grip the casing. The drill is capable of carrying one hundred and twenty feet . - of casing plus bits. Extra pipe and supplies must be carried by an auxiliary supply vehicle. The Becker double-wall casing is a complex product fabricated from two heavy duty pipes, plus one female and male tool joint. . . The two pipes are assembled concentrically with the inner pipe . . being easily replaceable if damaged.. An "0" ring seal on one end of the inner pipe seals one inner pipe to the other without leaks. With this construction, only the outer pipe takes the impact during the hammering cycle. Inner pipe floats in~ide against a neophyrene cushion. ~~v J*:A-S~k-,#:f.::..

The bits Gome in various designs to suit different formations encountered. Depending on conditions, bit life varies from 300 -··"··--··1 . I-- t ~ 3 r r 1.·. ' ' . [ g . t' l f ' ,J ,r M. ·--' L·, L. to 1,500 feet. The in-going air from the deck-mounted compressor and the air rettiffi a~~ di§ttibuted to their proper places by the drive spout, which hangs underneath the diesel hammer and which also -. transfers the impact from the hammer to the casing. The drill with tandem truck weighs approximately 20 tons (Figure 3). OPERATION ... This particular drill over the past twenty some years, has been mounted on a complete variety of configurations such as: -s1=ids -steel tracks (Figure 4) -soft track {Figure 5) -terra tire tandem truck -barge {Figure 6) -ocean going vessel (Figure 7) For the purpose of our discussions in this paper, we will concentrate most of our thinking to the standard truc~-mounted drill. The truck-mounted rig is highly mobile and travels the highway at 50 mph. On sites accessible to a truck, the rig can drive in, level up, raize the mast and be drilling in less than ten minuteso Many drill sites are of course, not directly accessible and in such cases it beocmes necessary to prepare roads with a dozer; and in some. ·~i9· es the dozer is required for towing assistance. To drirl the bit is threaded to the outer wall of the double , . wall casing, tp·e spout lowered over the casing, and the mast -...:. ... ., ... ·' plumbed. The ram inside the diesel hammer is lifted hydraulically, then dropped. The ram compresses the air-diesel fuel mixture, and. explosion occurs, driving the casing into the ground, and lifting the ram for the next stroke. As long as fuel is injected, the cycle automatically repeats itself at the rate of 95 blows per minute. Diesel consumption is three gallons in a ten hour shift. The compressor is now activated. The air is forced down the annulus and ports just above the bit direct the air to the inside . where it returns up the center of the inner pipe with all of the 4 ~r ~· ~ .. ' . 1'' ~· l' J l, J.

Cutting lift is a result of airspeed . . . of approximately 5,000.feet per minute rather than air pressure. . .. .. - This process of continuous air lift as part of the drilling process provides a continuous accurate sample of the penetrated . . formation. Since the drilling fluid is air, rather than water, .. .. .. . ,. . the sample is basically unchanged and strata changed can be easily pinpointed. To reduce dust loss, the discharged sample is collected in a cyclone. Angle holes can be drilled up to an angle of 45 degrees off verticalo Due to the handling of the heavy casing and reduced efficiency of the diesel pile hammer 7 progress is definitely slower. Drill·ing below the water table or into artesian conditions or int,~ heavily water-bearing sands, it becomes necessary to . . use water for the drilling fluid instead of airo The drill is equipped with a water injection pump for this purpose. In ten minutes, a hydraulic rotary drive can be affixed under the diesel hammer. Large boulders can be triconed or bedrock can be cored using the "N" series core barrel. Extensive diamond drilling with such a large rig is not recommended. PERFORMANCE The Becker Hammer Drill can penetrate any type of overburden, but will penetrate bedrock for only a few feet. Highly fractured and oxidized zones may possibly be penetrated to a greater depth. The rate of penetration varies considerably with the type of overburden.

COST A very distinct advantage of the Becker Hammer Drill for overburden sampling is that it is fast and more economical than other mehtods. This means that within allotted time and finances, . . a greater number of holes c~n be drilled and sampled accurately~ Due to the drilling speed, an ~ndirect saving occurs; the cost of inspection is significantly reduced. As a fact, in many instances, the cost of d~illing with the Becker Hammer Drill has been less than what the cost of inspectioti alone would have been with other methods • - 6 r r t r F L ' I t ... t " ' ! 1 • SECTION III MAIN USES GEOLOGICAL SAMPLING OF OVERBURDEN -gravel and placer deposits . . -setting casing for diamond d~illing -nickel laterite explanation -tailings or dump exploration -offshore exploration -tin exploration -freeze holes 2.

Item 1, GEOLOGICAL SAMPLING OF OVERBURDEN There have been untold numbers of aritcles and books published relating to various phases of alluvial mining (both offshore and onshore). With very few exceptions, none has related to or provided any record of the results of mining, versus that expected from exploration. The records of existing experience in unconsolidated formations, both on shore and offshore, have developed records that can at least be used and are necessary in 7 ]·-·- ! ' ' i I r r \ . evaluating new proper~~es. On shore, the precious metals, gold and platinum group, have been found in the greatest variety and types· of formatj ~ns. . . - They range from tough clays, tightly compacted and cemented gravels and boulders, to looser formations. The standard drill used onshore in past and present times has been the churn drill. Althougb slow in progress, the churn drill is not adaptable to offshore work because it is not practical or adaptable to offshore environments. Volume measurements are extremely important for combined with . .. . . metal values, the percentage of volume obtained to that actually existing in the formations will assist in calculating the effective . evaluation.

However, it has become apparent to most soils engineers that the many unique features make it a superb tool for engineering studies of soil properties • The Becker Hammer Drill is extremely versatile, but by no -. . ... means is it the universal tool which is ideal in each and every -. . situation. It will drill any soil formation, regardless of the variable conditions. This offers one distinct advantage to the engineer, and that is where formations to be ~ncountered are unknown, the Becker Drill will be able to penetrate and complete the hole. Just as the continuous sample is suitable for the geologist, . . the geotechnical engineer will readily appreciate the unaltered b~t severely disturbed sample that is truly representative and indicative of any changes in strata. The sample can easily provide . . grain size determination in gPanular soils and moisture content in cohesive soils. The continuous sample ensures that no critical formations, for example: soft seams, organic lay~rs, slickensides, etc. are missed. With other drills that sample by tube sampling, half of the samole could be missed and critical areas overlooked. The ~ rapid progress of the drill does have its shortcomings. Because of the continuous and rapid progress of the sampling procedure, it usually justifies tha presence of a soils engineer at the drill at all times. Such direct control is advantageous but experience has shown that the engineer does not like to spend a full continuous shift at the drill. STANDARD PENETRATION TEST The Becker Hammer Drill is fully equipped for Standard Penetration Testing (SPT) using a 2" O .. D .. splitspoon, advanced by means of an automatic 140 lb5 hammer with a free 30 inch hammer drop. 10 1 r l r r l .. SHELBY SAMPLING Three inch diameter shelby tubes for laboratory strength testing can be taken when desired. Using the 6,000 lb. diesel pile hammer as a weight, the samples are advanced by pushing, HYDRAULIC PISTON SAMPLING In cases where ext~eme!y soft soils are present, a hydraulic piston sampler can be used~ The sampler is advanced ~bead of the casing in closed position; at the desired depth, the sample is taken by applying hydraulic pressure through the extension rods. This method eliminates any drilling disturbance and assures the highest possible quality of sample. SAMPLING GLACIAL TILL Where samples for lab testing are required of denser soils, such as glacial till, 2~" diameter heavy wall tubes are driven. DENISON SAMPLER Samples of ha~d clays and cemented soils can be recovered using a Denison Sampler. CONTINUOUS BLOW COUNT As the hole is advanced, blow count on the advancement of the Becker open casing {BOC} provides continuous information regarding the densness of the soil. The approximate relation between BOC and SPT is: SPT= ~ X BOC The BOC value is a valid value in most soils, however, in water bearing sands, it is totally meaningless due to quicking and heaving of the sand. While engineers highly experienced with the BOC might eliminate the SPT altogether, most engineers will use it as a complement to the SPT. The BOC has the advantage of beins continuous, thus covering the space between the SPT. DENSITY DETERMINATION Determination of the density of any sand-gravel formation, or of a water bearing sand, is an extrememly difficult under- taking. The standard SPT yields questionable results. To Q;!!4!4S- 1 1 r r l l l f I i ~. .. ) ,, i i. ~-·. overcome this problem, Becker has developed a new method, the Becker Density Test (BDT) (Figure 8}. The bottom of the Becker casing is closed off, the air is shut off and the casing is driven as a giant penetrometer. The BDT has been found highly sensitive, more accurate and with a wider range than the SPT. The numerical relation between SPT and BDT is 1. Normally, a convention~l Becker sample hole is drilled adjacent to the BDT. The combination of the two holes thus provides continuous blow count plus continuous sample (Figures 9 to 15 inclusive)c TESTING FOR PILES For any project where piles might be a c6nsideration, the . BDT js a vastly superior exploration tool; it is in fact, a pile driving test on a 5 inch closed end pile. INSTRUMENT INSTALLATIONS Because of the open cased hole, the Becker Drill is well suited for any type of installations such as piezometer instruments or slope indicators. WATER INFORMATION In any engineering program where accurate information regarding soil/water characteristics are importantr the Becker Hammer is the most suitable drill; the features of the rig combined with pertinent procedures, will provide more accurate information than any other drill. (a) The hole is cased at all times~ (b) No drilling mud is used. (c) No water is intoduced into the soil. (d). Air is used for drill_ing, therefore, the presence or absence of water can be detected. (e) Rising, falling or constant head permeability test can be run at any time. (f) The double wall pipe system provides a built-in airlift system so that mini pumping tests can be run if so desi~ed. (g) Due to the cased hole, no mud features, and rapid and controlled pulling of the casing, the Becker Hammer is perfect for piezometer installations. - 12 r r . r \ f . I f ,.

Now with the Becker Drill, aquifers can be located in a fraction of the time and cost . CASE HISTORIES 1. Alyeska Pipeline Service Company Project was a final ( 1974) .belowground Mode Confirmation . In ~therwords, the drilling program was to make a final determination of precise transition points between elevated and buried sections of the oil pipeline. Some other uncertainties also had to be resolved such as, depth of burial and the exact location of shallow ice lenses that may require construction mode changes. Twelve transition points were tested and two were relocated. There was a rush on the project due to early thaws and early road restrictions. All equipment therefore had to be brought to Alaska via Hercules aircraft. Customs inspections and assembly was done in one day and ready for a 100 mile trip over ice roads, river ice, snow drjfts and ungraded terrain. The crew consisted of three men and began on April 28, 1974 and 46 holes were completed by May 9, 1974. All drilling was done below budget and in less time than estimated • .J974 Drilling Program Actual Engineer's Cost Estimate Scope of work 49 ~rfl ~ 70 (No. of holes) 12 42 Drilling Costs Mob-Demob 45,000 30,000 Operations 46,000 183,800 Expendables 900 9,400 92' 100 223,200 13 r l . . f l r l r l l •' • ' .

In 1973 working time and standby were paid at the same rate. In 1974 the standby rate was approximately 60% of the working rate.

TARABELLA DAM -WEST PAKISTAN At this 1966 site of the world's largest earthfill dam, the river valley presented a unique drilling problem in that sediments in the valley consisted of dense cobbles and silt up to 600 feet deep. It was necessary to find out the extent of open water channels that required groutinge . . A larger hammer drill, the Model 440 was developed. The Becker equipment drilled three rows across the Valley from 200' to 250' each at a spacing of 50 feet apart. Total footage was 68,000 feeto Then, 20" drain wells were drilled. A 6" diameter stainless steel screen and riser pipe was set in the hole. At completion, the flow from these wells was directe~ back into the river by means of a concrete spillway~ The original de-watertng well program consisted of 120 wells up to 250 feet in depth for a total footage of 27,000 feet. After the dam was filled, additional relief wells were required. An additional 70 wells were installed. 15 1 SECTION III-Item 3 CONSTRUCTION DRILLING Guy Anchors Over the past dozen years, the use of guy anchors, drilled into overburden and rock to sup9ort transmission line towers, has increased rapidly. The Becker Drill has been found the most versatile and suitable for this application. On most transmission lines, anchors are installed ~t an angle of 38 degrees to 45 degrees from vertical (Figures 16 to 19 inclusive)~ a} As most transmission lines cover.great distancest it is impractical to perform prior soil sampling at every tower and every hole.· Yet, at the time of installation, it is imperative for the engineers to know the soil type in each hole so that the anchor length can be adjusted· should unexpected, unconsol- idated soils be encountered& The Becker drilling method, with it's continuous sample return, provides this vital information. b) As neither water nor drilling mud are used in. the Becker drilling, there is no softening and loss of ~oil strength, nor any lubrication and reduction of friction. c) No. caving or loosening of the formation occurs, as the hole is casedo d) Where bedrock is encountered at a shallower depth than the required overburden anchor length, the doubl~ wall casing is seated into the rock, sealing off the overburden. A percussion type rockdrill incorporated into the Becker unit is then used to drill the required length into the bedrock. e) When the total depth is reached, the anchor rod with a tremie hose attached, is lowered to the bottom of the hole. The grout is pumped into place through the tremie hose, thus fillipg the hole from the bottom upwards, When the hole is filled with grout to the surface, the tremie hose is withdrawn and the drive pipe pulled outt The top portion of the hole . is then filled with grout pumped in from the top. Installation of transmission line anchors in rough formations is one of the most specialized and difficult under- takings in today's construction industry. 16 -.. -------r- j C&ll:oe;:c: J UPLIFT ANCHORS Construction of tanksi tunnels, abutment~t etc~, al~9 require anchors. The application is the same as with Guy Anchors except that they are vertical. TIE-BACKS Tie-back ru!choring has now established itself as a superior method of shoring. Where tie-backs are to be installed through gravel or till formations, the Becker Hammer is usually the best method, as it offers a cased hole and assurance thqt .... ~ difficult formation can be penetrated .. CAST-IN-PLACE PILES Because of its ability to penetrate gravel and bOUl~~r formations, the Becker Hammer lends itself tQ ~h~ procedure of installing cast in place piles through such f6~matians and · socketing the piles into bedrocko GROUTING When grout curtains through sand-gravel formations are required, the Becker Hammer is the natural choice. Not only is it more economical than other methods, but it is often the only method that can complete the drilling program within tne tight schedule usually associated with such projeats. Since "' the double wall pipe has an open center, a grout packer is set at the drive shoe; the grouting then proceeds until the desired grout pressure is attained, at which time the double wall drill pipe is pulled up the desired distance and the grouting process repeated. At the Tarbela damsite in West Pakistan, the Becker Hammer has drilled over 100)000 feet of grout holes through one of the toughest gravel formations ever encountered. LARGE DIAMETER CASING (TRIPLE TUBE) ~----------------------------~ . Installation of large diameter casing for relief wells and . . dewatering wells, through sand-gravel boulder formations, is a slow and costly procedure. Becker has developed a special technique as well as a recently designed larger drill, Model H-520 capable of imparting 30,000 ft. lb. at 85 strokes/minute (Figure 20). The drive pipe is usually 12" or 18" inside diameter and 17 f' t~ f·,: ' ~ l . l 16" or 20" outer diameter. A third casing is fitted over the drive pipe with an oversize bit machined to allow the outer casing a tight fit. High pressure air is forced down the annulus between the dual wall drive pipe. The air and cuttings return up the center of the inner pipe. The outer casing sleeve is being simultaneously driven down together with the dual wall drive pipe. When the desired depth is reached, the dual wall drive pipe is wi thdra\.zn, leaving the outer casing in the hole.. This casing is capable of withstanding normal end bearing and lateral bearing loads to be utilized as a pile. The casing can also be used to keep the hole open while a support member of different design or material can be inserted and slurried in the hole. Specially designed hydraulic casing pullers are then employed to remove the outer casing for reuse on other holes (figure 21}~ This triple-tube method is faster than the conventional methods of drilling large diameter holes and has the ability of always being able to guarantee an open hole in alluvial soils either in frozen, semi-frozen, or thawed conditions. The outer casing also acts as an insulator from the effects of the colq temperatures of the perma frost~ CASE HISTORIES Guy Anchors a) Client: Manitoba Hydro Grand Rap ds 136 miles b) Location: Distance: Total Anchors: 3,900 Total Footage: 104,600' Average Depth: 26.8' Test load (KIPS): 65 to Cross Lake Average Cost/Ancpor: $362.00 Client: Ontario Hydro Location: Sudbury to Parry Sound Distance: 40 Miles Total Acnhors: 690 ·- 18 I • 1:, t:, Case Histories, Cont.

Care should be exercised that the full hammer energy of 8,000 ft/lbs. is delivered and 19 ······-y ~ #U¢w--.. ~ that sufficient compressed air is provided to rapidly clean cuttings. Blow count should be kept in 6 inch increments · to fully define the degree of stratification and the presence of boulders. A 2-man field engineering crew should be used with one man directing operations and keeping blow count with a tally page and the other continuously observing cuttings recovery and taking samples. Reference samples of cuttings should be taken at 5 foot intervals or each soil change, whichever is less. Where sand layers are encountered, standard penetration tests should be performed. Shelby tube or open-end dri.ve samples should be taken of any clay or clayey sand layers encountered. ---~r---~ ·:-~=-----------~----------------------------------------------------------- ii ! 20 _r~ l j f. \ \ • I r L.

I I I ' l BEARING VALUES AfoJD OTHEn CCRnELATIC"~JS ARE AVAILABt.E FOH THE SPT. HOW CAr·J THE CORRESPOf~Dif.JG BOT VALUE BE APPLIED? WHAT ABOUT TESTING FOR PILING? The BECKER DENSITY TEST is a new soils l'lnci foundiltion explcr~tion tool in the form of a giant ~:ynamic ~netrom~ter. It measures the Denseness of the ooil. The regular 5W' Bec~er Drill Pipe is blocked off a! the bit, the dritling air is shut off, and the pipe is driven by the diC"'"..cl pile driving hammer as if it was a steel pile, counting the blows for each toot of advancement. The BOT is very scnsiti\•e yet has a wide meJsuring range. It is ., highly accurate tool with none of the 'wild' values frequent!~· produced by the Sti:!ndard Penetration Test (SPT). There are four main reasons why the COT provides a more accuriltc Density index: i. The driving is mcchi:nical-influence of human factors (skill/errors) is reduced. · 2. No hole is drilled -there is no drilling disturbance. 3. lnsig""ificant local variations, for example small rocks, produce dramatic~Jiy misleading SPT values. The BDT is a test on a much larger scale, not influenced I.Jy minor local anomalies. 4. The SPT is intermittent (usunlly 5 ft. sp::~cing) whereas the BOT is continuous, provitiirtg five tests in fivr: feet. In !>urnm~ry, £>ach individual BDT value is more accurate, and therr arc five times as many Villues, continuous through the formation. Normally the BDT is less than half the cost of u correspondinu drill hole \'llith SPT at five foot interval:;. By drillino a conventional Decker Drill Hola be!iidr. ths BOT, continuous, representative snmrles are obt;:ined r.nd ground wnttr inforrn11tion provid!::d. Usual I~· a DDT r.nd ;· ,: 'r;kor S3mplo Ho!a csn be. run for lc~s cost th<m on!l SPT hole. For vranular formations where information on the Dan~nC<"..s of tho soil is required. Dr ivinp calibrations indicate that-by coinciden!X'-the evc-r::;r. numNir:l'l rC'IJtion b::-t\·,~ccn SPT ;:nd SOT is 1:1, it is therefore very simple to use the conventional SPT rorrr.lations. For -.ny project where piles miHht IJc cnnsiderrd, the BDT is a vastly S\lpcdor cxplorlltion tool. It ir. in fact a pile driving test on a 5" cln~l!d end pipe pile. fli)URt NO. 8 -- ------------ T • J : i .• ~ '! --1 :.:J:."f-·-"' .... ·_·_-_. _. _. "i· -, ........ .;.-. ... -' .

IJsing 5%" o.d. x 3%'' i.d. drill pipe, the hammer is capable of drilling to a depth of 350 ft, dependent upon soil conditions. For maximum efficiency when adding or pulling drill pipe the hamme; retracts out of the way. Angl9 and \fsdical Drii!lng The drill is designed to drill holes from vertical to 45° off verncal, The lateral trav'el of the mast on the deck allows the hole to be positioned within working distance of the operator. When pulling hammer pipe the attached puller assembly reacts against unstable ground conditions causing a load on the mast. The pressure relief valve on the mast slide cylinders eliminates this load on the mast. Oo~rator's Console The operator in position at the console can control the total drilling "~peration, from starting the motor to levelling the drill unit and commencing drilling. Gauges for hydraulic oil pressure, water and air pressure are clearly visible for inspection. The controls are arranged in a logical sequence so that each drilling procedure can be carried out smoothly .
