Application November :5, 1032, Serial No. 044,101

- s 2 Claims. (01. s1- -s:) My invention relates to new and'useful proc-.

esses of building underground walls, foundations, supports or walled ditches, and like structures, and has for its object to materially lessen the time and cost of constructing the same. My

processes also make it possible to use a plastic material such as clay, for building a wall for the purpose of holding water, oil or gas or retarding its percolation in the ground, or to use a liquid asphalt or oil or a. cheap mixture of low cement content in building such a wall, or a supersaturated solution of calcium carbonate or water glass solution or other minerals or salts as a cementing medium or any other medium which can beintroduced and mixed in a fluid or powdered form with other material such as earth material and which will then harden, coagulate or congeal by cooling or setting or being sub- Jected to a chemical reagent to solidify or bind the mass of the admixture. One of the chief features of the processes is the simultaneous excavating of the earth and the building of the hard earth, clay,- soil, sand, gravel, quicksand,

soft mud and the like.

with the above and other obiects in view? which will appear as the description proceeds,

. my invention consists in the novel features hereinafter set forth in detail, illustrated in the accompanying drawings and more particularly pointed out in the appended claims. 7

Referring to the drawings in which numerals or like character designate similar parts throughout the severalyiews; there are two groups of drawings, one group, comprising Figures 1 to 22 inclusive and Figures 2'7 and 28 and Figures'31 to 35 inclusive relating to my rotary drill, cutting tool and conveyer type of apparatus, and the other group comprising Figures 23 to27 inclusive and Figures 29 and 30, concerning'my belt form of cutting tool and conveyer type of apparatus which is more generally adapted to use in building walls in hard earth material than is my rotary form of equipment. Dealing with the first group: Fig. 1 is a view in front elevation of my rotary apparatus above mentioned, indicated as being mounted on a heavy tractor ,or other movable structure, said apparatus consisting of two coacting rotary drill, cutting and conveyer screws, with drill bits thereon, which .will hereinafter be referred to generally as rotary pipes whether the same is operated for boring, cutting laterally, or .5 for conveying, and which sai'd rotary pipes are suspended from a gear case which in turn is hung fromblocks on a derrick, with'a rotary table superimposed on said structure and having therein adrill stem which itself is suspendedbyl a swivel socket from a block held on a super structure above the rotary table, andshowing a chain drive to said rotary table, afluid hose connection into the rotary pipes and cables with which to raise or lower the drill stem' and gear 15 case.

V Therotary pipe-head i6 is provided with hose connection 22, and hose nthrough which fluid mixture may be forced into the;rotary. pipes through'aperturesil in saidisleeves II and I9.

'Stufling'boxes of conventional arrangement and whichare' not shown',*pack oi! said sleeves from the partition 28 which divides thergear case 7 Attached to each of the sleeves i8 and 19, are

rotary pipes made up in sections adapted to be connected together by tool joints, and also adapted to be connected to said sleeves and with the bits in the same manner, one string of rotary pipe 28 being connected into sleeve l8 and the other string of rotary pipe 21 being connected into sleeve I 9. It will be noted that with the arrangement provided the two strings will be rotated in opposite directions. On the sections of pipe comprising the strings are worms or spiral flights or vanes 28, which may also be a series of separate vanes, arranged in the desired pitch. Holes 29 in the rotary pipe permit water or cement or clay mud or other liquid mixture, to be forced-into the hole being drilled or the trench being dug, and when the use of the holes is not desired they may be plugged or pipe without holes substituted therefor. Drill bits, such as the conventional fish tail bits 30, are attached to the bottom of the strings of rotary pipe and they are also provided with holes 31 communicating with the inside of the respective string of pipe into which they may be connected.

Presuming the mounted apparatus to be moving in the direction indicated by the arrow shown in Fig. 2, to the rear of said rotary pipes is attached a shield 32 which serves a number of. uses as previously set forth, and which is made in sections corresponding to those of the rotary pipe and attachable thereto by means of a flange portion 32 thereof adapted to receive the end portion of the pipe which may be passed through holes 24 in said flange portions of the shield. Hinged to the bottom of shield 32 may be provided a tail board or hingedshield plate 32A which may follow in the wake of the drill bits 30. The two-strings of rotary pipe 26 and 21, are held together in spaced relationship and parallel with each other, by yokes 25 placed in the string of pipe at each joint thereof as shown in Figs. 5 and 7.

Figs. 11, 12 and 13 disclose another shield arrangement wherein a shield proper 36, is provided with side wings 21 hinged thereto, and which after the excavation has been connected may be run into the trench prior to starting the placement of the wall therein. The tips of the side wings may be formed of a resilient material in the nature of a flap 31A as shownin Fig. 31. Attached to the shield and to the rear thereof is a pipe 38 with perforations 39 therein through which wall material may be inserted into the ditch as it is dug. An inner pipe 38A, such as shown in Fig; 32 may be run in pipe 38 through which the wall material may be introduced into the pipe 38 at the bottom thereof when closed at the bottom as shown. may be made. with a curved plate 88 which permits pipe 38 to drag on the bottom of the ditch.

Fig. 15 shows a modified form of spiral flight 40 for the rotary pipes, in which the edges of the spiral are provided with teeth 4| to aid in cutting away the earth material. 7

In Figs. l6, l7 and 18 is shown shield 36 with side wings 43 in modified form, said wings being provided with housing 44 for rolls of lining material 45 such as a fabric or paper, for lining the side walls of the trench preparatory to filling the same with wall material. The lining material is rolled on rod 48 and inserted into thehousing on said rod and the rod seated in a thrust bearing The closure of pipe 38 r 41 in the bottom of the housing. The lining material is shown in Fig. 18 as extending through g the housing and held in place in the trench by bars 48 until the wall material has been placed in the trench against the lining material, wherer 5 upon the lining material is, of course, held in place by the wall material. Tension plates 49 loosely grip the lining material and prevent the wall material from passing into the housing.

In this group of figures is also shown a longitudinally slit pipe 50 with slot it running the length of the string of pipe and through which wall material may be conveyed into the trench.

In Figs. 19, 20 and 21 is shown'a shield such as shield 32 with pipe 62 fastened to'the rear thereof and slotted as by slot 53 with enlarged opening 54 at both ends of said slot and adapted to permit of the insertion of a cross-T 55 into the pipe through the enlarged opening at the top and to the ejection of 'the cross-T out of the pipe through the enlarged opening at the bottom of the pipe. The cross-T 56 may be either of a reinforcing bar such as bar I8, or of a connection 51 attached to a form such as a board or plate form comprising sides 58 and bottom 59 held together by bar 80 with which connection 51 is directly attached. In pipe 52 is a worm conveyor 6| with which the T 55 may be forced to the bottom of the pipe. The conveyer is also adapted to force cement or other liquid or powdered mixture through pipe I2 after it has been introduced into said pipe through head 62 into which a hose 83 or a hopper 63A is connected, or with both hose and hopper connected into the head as shown in Fig. 19. The worm I is drivenby shaft (i4 and chain and sprocket drive 65.

In Figs. 33 to 35 inclusive, a slotted pipe such as pipe 52, with worm such as worm conveyer 6| in said pipe appearing in Fig. 19, is shown. A

wheel 89 having protruding spokes, teeth or cogs 90, is held in a yoke 9| on said pipe. The cogs of the wheel are meshed with the spiral of the conveyer and protrude into the pipe through the longitudinal slot therein. The yoke 9| grasps the pipe loosely, so that the wheel may be run to the bottom'of the ditch on said pipe, and then rotated by turning the worm conveyer I. The teeth of the wheel bite into the bottom surfaceof the ditch and as the wheel is rotated by the worm the entire structure is urged forward. This arrangement serves to assist the tractor at the surface of the ground to force the rotary pipes against the front wall of the ditch. Preferably, pipe 52 is attached to shield 32 by'a web 82 so that there will be no obstructions on saidpipe on which yoke 9| may impede in traveling to the bottom. The pusher whecl may be withdrawn by reversing the direction of rotationof the con veyer 6|.

In the second group of drawings, consisting of Figs. 23 to 30 inclusive, a link belt conveyer type of apparatus is shown in which .66 represents generally a tractor or other movable structure bearing the apparatus which consists of a link belt conveyer wherein G1 is the chain and 6B the driving sprocket whichreceives its power through shaft 69 from chain'and sprocket drive 10; The conveyer has conventional digging. buckets ll thereon, and the whole is pivotallysuspended 70 I coupling 14 is hollow as if of pipe construction bewas the two sprocket wheel shaft heads,and

is provided with an inlet "and hose connection II thereto connected, wherewith liquid may beforced into the pipe part ofthe coupling member 14 and be conveyed'to the outlets 10 in fthe pipe. The belt and theficoupling may be of any desired'length by substituting various lengths of 'coupling members, and belt. A conventional lateral conveyer 11 receives "the earth material from the buckets 1| and conveys the same to one side of the ditch, while a hopper 18 and pipe 19 conveys'th'e wall material to a trough 80 hinged on the apparatus as at, M, the trough being made 1 r of a'bottom plate 3i, side plates 82 hinged there onrand a tailplate 83 also hinged thereon, the

5 bottom plate and the side plates forming a winged shield interposed between the conveyer and the wall material when the same is, placed in the ditch and 'thetail plate likewise acting as a shield for the extreme lower portion of the conveyer. The pressure of the wall material against vthe shield assists in forcing the conveyer' buckets Q against the front face of'the ditch being dug.

In; Figs. 29 and 3 are shown my preferred j form of link' belt for; the intended purpose, the same comprising sprocket chainwith links '84 joined together by pins .5. with said pins having an enlargedcent'ralportion 38 thereof extending between the two links whereof it provides the pivot'member of the'links, and with plate members 81 hinged on the enlarged center portion of the pin, andwith'said plate members at intervals carrying a digging bucket or gouge orother bit' wherewithto remove'*'*the earth material. with such .a belt conveyer the loose earth material is held between'the conveyer belt plates 81 and the front'iace of the ditch being dug and a 1 lessens the'tendency of the loosened earth to pack certain parts thereof may or may not be used,

and clog the: apparatus. It is obvious that the plates '81 could beformed to extend over the links it suchan arrangement is desired. In /practicing my invention under various conditions and to accomplish a number of purposes and attainvarious results, it is obvious that the use of the equipment 'will'also vary and that and 'ii'used' may be 'use'dfin combination with 'various otherparts of myapparatus.

Itis alsoevident'that ajvariety of wall materials and cementing or binding substances may be ,used for various purposes under diii'erent circumstances to accomplishvarious objects;

: To illustrate, presuming that it is desired to build a-wall merely to stop or retard the undergroundflow'of'water down a valley, a clay mud would be sumcient as the wall would be supported on both sides andthe clay would be impervious to the water and not subject to erosion 'except at the surface. f This would also be truein building an underground reservoir wherein 'to' storewater, oil, gas and the like, whereas if it were desiredto build a ditch wall or jetty'or'insert a-core'in an earthen dyke,'or,build a pie'na r substantialwall, suchas ofcement, would be used, :Moreover, in certain cases it would be desirable to a mixture of the earth material itself 7 with a little cement, or with oil or asphalt, molten sulphur; paraflin or other wall material, in,

which case only a part of the earth material would be removed andthat part remaining would receive the cementvor other-binding agent} In such last mentioned case the cementing orZbind-f ing .orcongealing or coagulating agent, ormix ture thereof may be forced down through the rotary pipe 2 6 andlLor either, to'the bottom my the necessary amount to the The apparatus shown inits various forms and readily lendsitselfto the practice oi when desired to do so,

However,;where it is desired to build a firm or solid iwallor foundation, the; walll'or s foundation material may; beinserted through the pipe 38 in backo'f the shield lay-hydraulic or air pressure or by a'conveyer screw, leaving the pipe through the holes of the-slot therein, and in some cases the fluid mixmay be inserted through an inner pipe into the bottom of the pipe ll from whence it may flow upwardly; and out of the' holes'in pipe 38, or steam may be run through the inner pipeto keep the mixsufllciently hot to preserve its liquid state as in the case where molten sulphur or paraflln is used, or the hot mixture may be conveyed through one rotary pipe 21 while the other rotary pipe is used for co'nvey-v ing the heat, such as by steam or'other hot-vapors, or gases, to themass' f the mix. 7 a

Moreover, in cases where avery substantial. I wall or foundation is desired, instead of, mixing j concrete on the surface and injecting it into the" ditch, in liquid form, a dry mix maybe delivered from a hopper into the pipe {land forced-into 26' the ditch with a worm conveyer,,the necessary, 1

Fur-" 'thermore, in certaininstancescno water-for the v mix need be delivered, in asinuch as it may be 7 present in the earth in suilicient quantity to supvarious processes, andin examining the equipment; it is readily apparent'that, in addition to the matters above disclosed}, the equipmenthas L other functionsas well, In the rotary form of apparatus the" shield acts to separate earth material from wall material; also to assist thcworms the earth material, and, to assistlin mixing the oi the rotary pipe to lift to prevent the larger stones from being convcycd a into and lodging between the worms of therotary pipe; and also as a wall again'stwhich theweight of the liquid wall material: may lay press the rotary pipe cutters against the frontiacefof the ditch which is being cut. The tail board maybe used when desired to make the separationmorc complete. The wings ontheshield also a'ssistdn further separating earth'material from walli material. They also assist in creating further pressure oi the wall materialon therotary'pipe cutters as aforesaid. The resilient wing edges, tips or flaps further assist in this 'e's aect asthey follow of the side walls: ,The teeth a) cut into fairly hard earthmaterialand to,pulverize'it when desired to make it yery line for use as walln'laterial as previously m 'n V} fabric or paper lining attachment, makes it possible tostretchthe'linin'g along the side walls of' r the ditch to create a partial ortotalseparation,
