Abstract
Abstract The invention relates to a method and apparatus for effectively driving cylindrical piling into a substratum or soil having a consistency that would otherwise tend to plug the pile. The method consists of driving the pile, and constricting the compacted earthen plug at the lower end thereof. High pressure streams of fluid are then introduced at the pile lower end in a direction to erode, and break up the plug to prevent the latter from adhering to the pile walls. The disturbed fluidic mass at the pile lower end can then be removed or at least be rendered into a condition where it will not plug the pile. The apparatus comprises a cylindrical, metallic walled pipe. The lower end of the latter includes an annular shoe depending therefrom and having a constricted passage therein defined by a gradually tapering profile. A manifold formed in the shoe receives a high pressured fluid such as water, and directs the same through a plurality of orifices toward both the pile wall, and the confined plug.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
An elongated anchoring pile adapted to be driven into a penetrable substratum for a sufficient depth to be firmly embedded in the latter, which comprises; a. a cylindrical pile having a lower edge, and a uniform thickness wall extending substantially the length thereof, b. a driving shoe carried adjacent to the pile lower end, c. said driving shoe including an annular soil compacting surface spaced longitudinally from said lower end and terminating in a constricted annular collar, the latter having a set back rim extending from the constricted section to the pile inner wall, d. a plurality of discharge nozzles formed in said annular collar being communicated with a high pressure source of liquid.
Claim 2
Dependent Claim
114 words
An elongated anchoring pile adapted to be driven into a penetrable substratum for a sufficient depth to be firmly embedded in the latter, which comprises; a. a cylindrical pile having a lower edge, and a uniform thickness wall extending substantially the length thereof, b. a driving shoe carried adjacent to the pile lower end, c. said driving shoe including an annular soil compacting surface spaced longitudinally from said lower end and terminating in a constricted annular collar, the latter having a set back rim extending from the constricted section to the pile inner wall, d. a plurality of discharge nozzles formed in said annular collar being communicated with a high pressure source of liquid.
Claim 3
Dependent Claim
24 words
In an elongated anchoring pile as defined in claim 1, wherein said discharge nozzles open onto said setback rim and being directed radially therefrom.
Claim 4
Dependent Claim
22 words
In an elongated anchoring pile as defined in claim 1, wherein said respective discharge nozzles are disposed generally circumferentially about said rim.
Claim 5
Dependent Claim
35 words
In an elongated anchoring pile as defined in claim 3, including; conduit means communicated with said collar and with said high pressure source of liquid to form a high pressure source thereof in said manifold.
Claim 6
Dependent Claim
33 words
In an elongated anchoring pile as defined in claim 4, wherein said conduit includes; a plurality of conduit segments being detachably connected one to the other along the inner wall of said pile.
Claim 7
Dependent Claim
126 words
Method for embedding a cylindrical pile having an interior wall into a substratum, the latter being characterized by a propensity to compact within the pile interior and thereby form an earthen plug which hampers downward progress of the pile, which method includes the steps of; a. providing water jetting means at the pile lower end, having water jets therein, b. urging said pile downwardly into the substrate whereby to form said earthen plug at the pile interior, c. injecting a high pressure stream of water into said earthen plug, a portion of said high pressure stream being directed upwardly along said pile inner wall, whereby to disperse the constituents of the plug, d. repeating steps (b) and (c) in sequence as said pile is further embedded.
Claim 8
Dependent Claim
126 words

Claim 9
Dependent Claim
49 words
In the method as defined in claim 6, including the steps of; a. gradually compacting said earthen plug to form a constricted portion in the latter, and b. injecting said high pressure water stream along said pile inner wall at a point immediately adjacent to the plug constricted portion.
