  • the air gun repeater may be repetitively operated, each time abruptly releasing a charge of very high pressure gas, eg., compressed air, supplied throughv airline 28 under remote control via electrical cable 30.
  • the high pressure compressed air as supplied through the airline 28 from the compressor 24 typically charges the air gun repeater with air at high-pressures, for example, in the range from 1,000 to 3,000 pounds per square inch; however, higher or lower pressures may be used.

  • 'I'he tip 46 is welded to the pile around the periphery as indicated at 50 to provide firm attachment between the pile 12' and tip 46. This tip attachment must be sufficiently strong to avoid dislodgment during operation.
  • the piston weight 14 is of general cylindrical cross section like that of the pile bore 42 and of substantial longitudinal dimension to obtain a large mass.

It will be understood that other sizes of chamber volumes and other levels of air pressure may be utilized depending upon pile sizes and soil conditions. This specification sets forth above and hereinafter the sizes which I have found to work to advantage for driving piles into a gravel bed located beneath salt water, a difficult to penetrate soil condition.

  • the annular clearance space 5l around the massive piston 14 is a predetermined amount sufficient to allow the escape of the gas which has been abruptly released beneath the piston.
  • This clearance space 5l must not be too large, because it will then allow the high pressure gas to escape too rapidly before heaving the piston upwardly.
  • this clearance space 51 must not be too small, because it will then unduly restrict the escape of this gas.
  • the clearance between the exterior surface of the guide shoes-and the bore of the pile is typically Vs inch to, A inch on each side, i.e., a differential in diameters of one-quarter to one-half of an inch, thus providing proper guiding action while allowing suitable escape of the high pressure gas.
  • the guide shoes may be ring-shaped, or instead they may be segments of a circle with sufficient vertical gaps between seg ments to allow escape of the high pressure gas.
  • the piston 14 is provided with a central through bore 52 for accommodating the firing control cable 30 and air line 28.
  • the air gun repeater 16 is located adjacent to the lower end of the bore 52 for connection to the electrical cable and airline.
  • the airgun repeater 16 is firmly mounted and affixed to the bottom end of the piston weight 14 by a flange 54 and boltsl 56.
  • a counter bore S8 is provided to accommodate a solenoid valve 60 attached to the air gun repeater 16 and an airline connector 62.
  • the bottom end of the piston weight 14, the tip 46 of the pile 12' and the annular shoulder 48 define a chamber 64 containing liquid wherein the air gun is actuated.
  • a liquid supply conduit 66 formed in the piston 14 terminates in chamber 64 to supply water thereto and maintain the air gun submerged. Also, the flow of water down through the conduit passage 66 serves to purge any trapped air out of the chamber 64 before the air gun repeater 16 is actuated therein.
  • a check valve 68 is placed at the end of the conduit 66 and is operatively oriented to close in response to air gun actuation and thereby prevent transmittal of the high impulse through the water hose to the water pump. Thus, the water hose 32 and the water pump 34 connected thereto are isolated from this abrupt pressure impulse.
  • the piston weight 14 is freely mounted within the bore 42 with appropriate clearance 51 as discussed above. When the piston weight 14 is resting upon the shoulder 48, the sling 22, the cable and airline 30-28, as well as the flexible water hose 32 are loose with sufficient play to accommodate pile advances into the earth.
  • the airgun 16 is actuated by a suitableelectrical signal applied to the solenoid valve 60.
  • the solenoid valve 6 0 in turn causes an abrupt release into the water filled chamber 64 of a gaseous charge, e.g., compressed air, stored in the airgun chamber.
  • a gaseous charge e.g., compressed air
  • the gaseous discharge produces a huge thrust which is transmitted in all directions because of the incompressibility of the water. Downwardly directed components of this thrust or impulse act on the tip 46 as indicated by the arrows 72 in FlG. 3.
  • the pile tip 46 responds with an advance into the sediment or earth as illustratively suggested in FIG. 3 and effectively pulls" the entire pile 12 down into the soil. At the same time the upwardly directed portion of the impulse as indicated'by the arrow 74 drives the piston weight 14 upwardly under guidance from the bore wall away from the tip 46.
  • this method, system and apparatus serve to drive the hollow pile l2' in tension because the impulses are l applied at the lower end of the pile so as to pull" it down into the soil.
  • Two advantages are provided: (l) a thinner walled pile may be driven into the soil than when hammer blows are applied to its upper end, as is conventionally done, because the stresses imposed by this novel method are in tension rather than compression as is conventional. (2) The sudden tensile impulses which are transmitted upwardly along the pile wall cause the pile wall to contract slightly in accordance with Poisson's ratio, thus facilitating penetration by causing momentary shrinkage which reduces friction against the surrounding soil. ln a conventional pile driving operation the compressional blows at the top cause the pile wall momentarily to expand which tends to impede penetration.
  • the first driving impulse occurs upon the abrupt discharge of the air or other gases into the liquid lled chamber 64. This abrupt discharge also heaves the massive piston weight upwardly within the bore 42.
  • the second driving impulse of the sequence occurs a short time interval later when the massive piston weight falls down and impacts against the annular shoulder 48.
  • the first driving tension impulse of the sequence serves to agitate the soil surrounding the pile thus tending to reduce the impedance of the soil when the second driving tension impulse is applied soon afterward.
  • the piston weight 14 is enabled to fall relatively freely down through the bore 42.
  • the high pressure gas discharge rapidly expands so that its pressure drops quickly to a low value.
  • Substantial amounts of the gas and water blast upwardly through the clearance space 51 as indicated at 81 in FIG. 4, before the piston weight reaches the high point of its travel.
  • FIG. 5 illustrates a cross section of the pile and piston of FIG. 2.
  • the piston 14 is spaced from the pile inner wall with a clearance 5l as discussed in detail above.
  • the piston is formed of a solid steel cylindrical member.
  • the water conduit 66 and the cable conduit 52 are formed by drilling suitable passages at the desired locations during the formation of the piston.
  • the liquid flow restrictive relationship between the piston 14 and the wall of the bore'42 of the pile can be altered also by the effective length of the piston weight 14. For instance, by making the piston 14 very long, the fluid resistance as seen from the bottom end of the piston upon the high-pressure gas discharge may be quite large even though the clearance 51 is substantial. Hence, the length of the piston to some extent determines the size of the clearance 51.
  • a solid iron piston of about feet in length and ll inches in diameter advanced the pile 36 inches into a gravel soil beneath salt water with twenty-one actuations of the air gun.
  • the driving of a conventional sheet-type pile into the same gravel soil with a conventional pile driving hammer resulted in but slight penetration accompanied with substantial deformation of the top end of the sheet pile.
