US Patent:
5501550, Mar 26, 1996
Filed:
Jul 11, 1994
Appl. No.:
8/272561
Inventors:
Salvatore J. Calabrese - Burke VA
International Classification:
E02D 534
US Classification:
405232
Abstract:
A piling assembly is provided which comprises a casing unit comprising an upright hollow casing having a drive boot secured to the bottom of the casing, and an external mandrel adapted to be supported on the drive boot in surrounding relation with the casing. The mandrel includes a lateral opening therein which enables the mandrel to be placed around the casing through relative lateral movement. A driving force is applied to the mandrel so as to drive the drive boot into the ground such as to create a hole in the ground having walls spaced from the mandrel and casing and the resultant space is filled with grout. The mandrel is then removed and the casing filled with concrete.
