Abstract
A new pile is disclosed which includes a pile shaft and wedge-forming means of castable material spaced upward of the tip of the pile shaft and proximate thereto. The wedge-forming means cooperates with the portion of the pile beneath it, during driving, to cause the formation of a wedge of soil. The thus-formed soil wedge is in contact with other soil and the resulting soil-soil interface has enhanced pile supporting characteristics.
Claims32
A wedge-forming pile which comprises:
- (a) an elongated pile shaft having a bottom tip and an upper end and
- (b) wedge-forming means of castable material spaced upward of the tip of the pile shaft and proximate to said tip,
- (c) said pile shaft extending above and below said wedge-forming means,
- (d) the minimum combined width of said pile shaft and accompanying wedge-forming means from side wall to said wall being greater than the width of said pile shaft immediately above said wedge-forming means and greater than the width of said pile shaft immediately below said wedge-forming means,
- (e) the ratio of the height of said wedge-forming means to the width of said pile shaft immediately below said wedge-forming means being within the range of 2:1 through 3.5:1,
- (f) whereby the outer portions of said tip, said wedge-forming means and the portions of the pile shaft therebetween accommodate the formation of a soil wedge during driving of said pile.

Process of driving a pile which comprises (1) driving a wedge forming pile which includes
- (a) an elongated pile shaft having a bottom tip and an upper end and
- (b) wedge forming means of castable material spaced upward of the tip of the pile shaft and proximate to said tip,
- (c) said pile shaft extending above and below said wedge forming means,
- (d) the minimum combined width of said pile shaft and accompanying wedge forming means from side wall to side wall being greater than the width of said pile shaft immediately above said wedge forming means and greater than the width of said pile shaft immediately below said wedge forming means,
- (e) the ratio of the height of said wedge forming means to the width of said pile shaft immediately below said wedge forming means being within the range of 2:1 through 3.5:1,
- (f) whereby the outer portions of said tip, said wedge forming means and the portions of the pile shaft therebetween accomodate the formation of a soil wedge during driving of said pile.
