초록 ▼

A method and an apparatus is provided for forming successive overlapping voids in the ground along a predetermined course of travel and for producing a subterranean wall therein. The apparatus includes a mandrel for forming voids in the ground, and a pattern guide templet having repeating contours arranged on the ground for accurately guiding the mandrel along the predetermined course of travel during successive mandrel insertions. The mandrel includes a plurality of downwardly projecting spaced-apart cutting teeth for facilitating penetration of the mandrel into the ground, and a plurality of downwardly projecting high pressure nozzles for discharging an injectable material (e.g., slurry material or water) into the ground as the mandrel is inserted therein. The repeating contours of the pattern guide templet accurately receive and accommodate the cross-sectional shape of the mandrel during successive mandrel insertions so that successive overlapping voids are formed in the ground along the predetermined course of travel. The apparatus of the present invention further includes an installation rig for inserting structural elements into the successive overlapping voids formed by the mandrel. In this way, a subterranean wall comprised of liquid impervious slurry material and/or contiguous structural elements may be conveniently produced in the successive overlapping voids.

[ We claim:] [1.] Apparatus for forming successive overlapping voids in the ground along a predetermined course of travel to facilitate the construction of a continuous subterranean wall therein, which comprises:a mandrel for forming voids in the ground, the mandrel having a length, a longitudinal axis, a cross-sectional shape, a top portion which is attachable to a vibratory driver, and a bottom portion which penetrates the ground, a plurality of high pressure nozzles for discharging an injectable material into the ground as the mandrel is inserted therein, the injectable material being supplied to the high pressure nozzles through high pressure piping arranged at least partially along the length of the mandrel; anda pattern guide templet arranged on the ground for accurately guiding the mandrel along the predetermined course of travel during successive mandrel insertions into and subsequent withdrawals from the ground, the pattern guide templet having a plurality of adjacently disposed and similarly-configured repeating contours, each repeating contour having a shape which is substantially similar to the cross-sectional shape of the mandrel, the repeating contours receiving and accommodating the cross-sectional shape of the mandrel and no other structural elements during successive mandrel insertions and withdrawals so that successive overlapping voids are formed in the ground along the predetermined course of travel.
