JET SHEET CIRCULAR PILE WITH WATER HAMMER ASSIST BACKGROUND OF THE INVENTION This invention relates to improvements in sheet steel piles which have various sectional configurations and are used to form retaining walls, cut-off walls and cellular coffer-dams and, more particularly, to a method and apparatus for lubricating the working surface of the pile as it is being driven.
It is well known to those experienced in the driving of sheet pilling that earth strata varies from pure sand to dense clay with some cobbles. Furthermore, it has been determined that when a driven pile tip severs a clay strata, the residual moisture is driven away from the clay nearest the sheet pile surface causing greater adhesion than normal, and thus reduces and hinders the piercing ability of the sheet. Also, it has been learned that the wedging or binding effect of the soil that becomes locked in between the sheet pile tongue and groove members likewise absorbs driving energy and is likely to cause such heat to be generated that it melts the tongue and groove joint.
There are several different systems for driving sheet piles, one being an automatic impact hammer, and the like pile can be lowered into the earth under its own weight. In the later patent there is shown a drivable concrete pile that is provided with an embedded piping system and a form of interlock for serially driving piles, the arrangement being such that two lubricant jetsare directed downwardly and a divergently disposed third jet is made available for forcing water into the channels of an adjacent previously set pile so that the soil will be removed therefrom and the next drivenpile will be successfully interlocked with the earlier driven pile.
Accordingly, the principal object of the invention is to provide 'a system of controlled lubrication of the driven endsand longitudinally extending surfaces of all "adjacent sections of steel piling while they are being other a high frequency vibrator that sets a standing si- 2 nusoidal force wave which has no side motion and the latter system has proven to be about ten times faster than the former method and is particularly useful in soil strata formations that are more or less granular. Due to the high impact force of the automatic hammer, which is generally six times that of the high frequency vibrator in clay strata, the top and bottoms of the pile become bent and curled over and the interlocking elements spread and are ruptured. Also with the automatic impact hammer extraction of sheet piles as the temporary is impossible to remove them, thus causing a loss of the pile or portions thereof and incurring expensive underwater cut-off work.
The present invention has particular applicability for use either with the automatic impact hammer or the high frequency vibrator, the latter having had certain shortcomings since it was limited more or less to soil strata formations that are more or less granular. Because the high frequency vibrator had certain drawbacks in its use with different types of soil, excessive amounts of force have been developed but increase range has been limited to 5-10 percent. Thus, this improvement by alleviating or reducing soil strata adhesion to the sheet pile surface through the use of properly placed water jets broadens the use of the high he quency vibrator to include the entire range of sheet pile driving;
The prior art directed to improvements in piling which has been concerned with some form of lubrication to achieve entry of the piling into the ground, as well as its possible subsequent later removal therefrom driven by causing the soil that enters the interlock to be maintained in a viscous condition.
Still another object of the invention is to provide a system of driving sheet steel piling .which requires a less powerful driving force to be'employed to penetrate the soil strata thereby making it more economical to drive sheet piling.
Yet another object of the invention is to provide a system of lubrication for the sheet steel piling that not only enables the pile to be more quickly driven into the earth strata, but also to be extracted therefrom by a vi-' brator or automatic impact extractor.
V A further object of the present invention is to provide a system by which standard mill rolled sheet steel pile is disclosed in Bignell U.S. Pat.

DETAILED DESCRIPTION Turning now to the drawings that form the disclosure of this application, particular attention is directed to the fact that the manifolds disclosed herein and which are adapted to be associated with the duct system extending longitudinally of the sheet piling may be used with any of the well-known types of sheet piling, such as flat, 2" or deep arch.
The first embodiment of the inventive concept disclosed is best seen in FIG. 1, which is a cross-sectional view of a section of a sheet piling 10 of Z" configuration. This type of sheet piling is provided at the time of manufacture or subsequent thereto, e.g., by drilling with a row of uniformly spaced apertures 11-11 at the point of angulation of the parallel oppositely extending wings as shown, and these series of apertures which extend substantially the length of the sheet piling are covered by skip welding an arcuate plate 12 thereover with the edges of the curved plate 12 being so designed and arranged relative to the planar surface of the sheet of piling that a fan-shaped liquid spray is emitted laterally therefrom between the unwelded areas (orifices) and generally toward the opposite edges of the section of piling. This water flow is shown in dotted outline on the surface of the sheet. It is to be understood that the upper edge of these arcuate plates are fastened securely to the sheet piling to prevent leakage. The apertures 11-ll which extend through to the opposite inner portion of the section of piling are also covered with arcuate members, as shown, and these members 1313 also are skip welded thereto in spaced relation along the longitudinal extent thereof and in such a manner as to provide another series of oppositely directed jets through which fan-shaped sprays of lubricant may be emitted transversely of the planar surface of the section of of piling.
For reasons that will be apparent to those skilled in the sheet piling art and its use, the duct manifold for feeding the lubricant to the opposed channels l2-l2 and l3l3 will be positioned at a point below the upper extremity of the section of piling so that it will not be damaged during handling.
With further reference to FIG. 1, and since the several duct manifolds are identical only one will be described. The manifold generally indicated at 15 is formed by securely positioning, e.g., by welding a plate 16 at one end thereof to the section of piling adjacent to the interlocking groove l7'and at its opposite end to the intermediate web portion 10 of the Z-shaped piling 10.
By now referring to FIG. 2 it will be seen that plate 16 is adapted to be welded to the top of the arcuate member 12 and to have secured to the lower surface thereof the edge of a plate 18 and to the upper surface thereof a plate 20, thus completely closing in the area adjacent to the upper extremity of the feed lines to provide a lubricant chamber 22. The chamber 22 is fed lubricant through a threaded spud 24 which has means defining openings therein as shown at 26-26, access to the spud being provided by perforating the section of the wall of the piling, as shown in 30, and the front wall of closure member 16 by providing the perforation 32 therein. This threaded spud facilitates assembly of the water connection fitting with the manifold from either side it being understood that the unused opening in the spud will be furnished with a closure plug, not shown.
FIG. 3 shows another concept for a lubricant manifold adapted for feeding the channels 12-l2 and l3l3, as explained earlier in connection with FIG. 1.
In the embodiment of FIG. 3 aplate 16' is arranged to be welded at 34 to the plate 36, as shown, and is provided at its opposite end with a filler means .38 and together with top and bottom closure plates (only one shown at 39) the manifold chamber is completely en- .closed with access thereto being achieved by means of the nipple 40 that is positioned in an aperture 42 in the web as at 44. As explained earlier in connection with the description of FIG. 1, the water hose connection is made to the nipple 40 thereby feeding the lubricant through the perforations l1--1l, whereupon the fanshaped spray is emitted laterally of the surface area of the sheet piling toward the interlocks at the opposite edge portions thereof as explained earlier in the description of FIG. 1.
FIG. 4 shows the lower extremity of the sheet pile element 10 with the duct members terminating into a reciprocable drive shoe means 46, the assembly of which with the sheet piling is best shown in FIG. 5, all of which will now be described in greater detail.
In FIG. 4 there is shown a-front elevational view of a portion of a section of the sheet piling 10 into which the present inventive concept is incorporated and the drive shoe means 46 with the portion of the drive shoe removed to reveal its assembly with the sheet piling.
The sheet pile 10 is provided with a plurality of uniformly spaced vertically extending slots 48--48 which are adapted to receive the shank portions of rivets 50-50, these being best shown in FIGS. 5 and 6.
The drive shoe means 46 is arranged to slide freely adjacent to the terminal surface of the sheet piling and to thereby permit the lubricant which is transmitted to the shoe to travel laterally along the channel 52 (see FIGS. 4 and 5) andupwardly on adjacent sides of the sheet piling as well shown in FIG. 6. It will be noted from the viewof FIGS. 4 and 5 that a series of feed ports 54-54 transmit lubricant downwardly through the interior of a V-shaped hard metal tip 56 to a secondary channel 58 formed therein. The hard metal tip 56 l shoe.
The inventiveconcept as thus far disclosed reveals dual longitudinally extending duct elements that are secured to the web of sheet piling and arranged to feed lubricant laterally through fan-shaped jets (orifices) and over the web of the sheet piling as well as to the bottom area of the piling then through first and second channels positioned between. the drive shoe and the hard metal tip that iswelded thereto.
It is also to be understood that a dual duct system is not to be considered limitative of the preferred manner of delivering water to the web of the sheet piling and the drive shoe, for as shown in FIGS. 5 and 7 a single duct element may be utilized for feeding lubricant in a desired manner and to the areas of the sheet considered to be critical to a successful driving operation.
FIG. 7 shows a front elevational view of a sheet piling 10 of any of the earlier discussed types that is provided witha manifold 60 completely enclosed on opposite sides of the web and provided with a central perforated area'62 either of which may be plugged while the other is. used for the water connection. The duct 64 which descends to the bottom of thepiling may be of any suitable cross-sectional configuration.
FIG. .8 is a cross-sectional view on line 8--8 of FIG. 5 and shows the manner of assembly of the floating drive shoe 46 with the piling 10, all of which will be clear from the earlier description of FIG. 4. The drive shoe is secured to the sheet piling so as to reciprocate relative thereto and the primary and secondary channels are fed the lubricant in the'manner as described earlier herein.
FIG. 9 is an enlarged cross-sectional view on line 99 of FIG. 5 and clearly depicts the piling at 10, the respective portions of the duct element 64-64 to form the cylindrical feed channel for transporting the lubricant to the annular throat member 66 which is welded as at 68 to the duct 64'and terminates in a loose fit within the bore 70 of the drive shoe 46 so that water may be emitted upwardly toward the duct 64, as illusing a water hammer effect. Water hammer is well known and is the concussion which results when a moving volume of liquid in a pipe is suddenly arrested.
Accordingly, since this system of driving steel piling irrespective of its configuration utilizes a loose fitting drive shoe at the bottom of the section of piling, this provides together with the water or lubricant introduced to the shoe and the vibrator force for driving the piling a still further force known as waterhammer, a
phenomena that develops a shock force the liquid pump pressure.
As previously mentioned, to develop such a water hammer effect, it is merely necessary to momentarily stop the flow of liquid suddenly. This is achieved by the vibrators standing wave motion which jams the nipple up to 10 times 66 down against the bottom of the bore 70 in the drive shoe during the downward portion of pile excursion. This sudden blockage sets up a shock wave which has a pressure of about 3,000 psi in about 1/400 of a sec- .0nd and is fast enough to assist the force of the vibratory driver operating at about 15 cycles per second.
FIG. 10 is another embodiment of the invention wherein the inventive concept is applied to a circular pile.
In FIG. 10 there is shown a view of a circular pile whichis constructed of spacedly arranged concentric walls 72 and 74 that are adapted to be held throughout their length in a rigid driving relation by plug weld spacer means 76 and further arranged to have welded thereto at their upper extremity an annular vibrator I ring 78. Thelower portion of the pile is closedas at 80 by welding slotted vertical extension pieces 82 which can support by means of the rivets described earlier in connection with FIGS. 4 and 5 the drive shoe 46. The pile is provided with a nipple 84which is seated in a perforation in the outer wall 74 of the circular caisson and to which the hose may be attached during the driving operation. Water thus circulates through the circular pile and downwardly through parts 66' provided by the slotted members 82 and thence into the drive shoe and downwardly therethrough into the V-shaped hard metal tip which is skip welded around the perimeter of the drive shoe in such a manner that orifices will be provided at 86 for jetting water passing through the shoe upwardly, as described in connection with FIGS. 4, 5 and 6..Water passing through parts 66 is also jetted upwardly along the top edge of the shoe in the manner described in connection with FIGS. 4, 5 and 6.
It is believed to be apparent in view of the description of the water hammer phenomena availed of in connection with the sections of sheet steel piling described earlier that this same concept can also be used in the circular caisson and attention is directed to the similarity of construction at the right-hand corner of FIG. 10 when it is compared with FIG. 9. It will'be noted that the nipple 66' extends downwardly into the shoe 46 in the same manner as shown in FIG. 9 with the shoe 46 being secured in a reciprocable arrangement relative to the circular caisson.
FIG. 11 illustrates how a vibrator may be clamped to the top of the piling. A commerciably available vibrator 90, only a portion of which is shown is provided with a hydraulic cylinder 91 for operating one of a pair of clamping jaws which receive between them the upper edge of the piling to be driven. The jaw operated by the hydraulic cylinder having a piston rod 91a with a piston, not shown, in the cylinder. In order to use such a vibrator with the piling of this invention special clamping jaws are preferably provided as described below.
In FIG. 11 piling 92 is shown having a manifold 93 with openings on each side connected by a spud 94 having openings in its side wall. Duct 95 on the piling communicates with manifold 94 for purposes described heretofore. Jaw 96 has a sealing ring 97 which seals the opening in the manifold on the side of that jaw. law 98 operated by the hydraulic cylinder has a recessed portion 99 for receiving the manifold 93 and a sealing ring 100 on side 101 of the recess for sealing the adjacent opening in the manifold. A nipple 102 is welded to wall 103 of recess 99. The nipple 102 is screw threadidly connected with a water hose 104 and connects said hose with perforated spud 94 positioned in the manifold.
The vibrator is thussecurely clamped to the piling which at the same time a sealed connection of the water hose to the manifold is provided so that water supplied to the hose enters the manifold and then the duct 95 for purposes heretofore described. Suitable modifications of the clamping jaws may be made to accommodate the various types of manifolds and piling which may be used in the practice of the invention.
It is believed to be apparent-from the foregoing disclosure that those skilled in the art will conceive of variations for not only transmitting the water the full extent of the web as to the drive shoe; however, the disclosure herein is considered to be limited only by the claims appended hereto.
