Abstract
Process for soil treatment and successive installations of a plurality of equipments at different respective locations and apparatus for implementing said process, comprising the operations of: drilling the soil by driving a tubular stem tool having an axis and a predetermined overall diameter around its axis, introducing one equipment inside the tubular stem tool, removing from the soil said tubular stem tool while leaving the equipment within the soil, modifying the soil compacity around the equipment by mechanical action during at least part of the removal of the tubular stem tool and repeating the above operations with remaining equipments at other locations.
Claims22
A process for soil treatment and successive installations of a plurality of equipments at different respective locations in said soil comprising the operations of:
- drilling the soil at one of said locations by driving a tubular stem tool having an axis and a predetermined overall diameter around said axis, into said soil,
- introducing one of said equipments inside the tubular stem tool, down to a corresponding predetermined position for said one of said equipments with respect to said soil,
- removing from the soil said tubular stem tool while leaving said one of said equipments within the soil in said corresponding predetermined position,
- modifying the soil compacity within at least part of said predetermined overall diameter around said one of said equipments by mechanical action, during at least part of the removal of said tubular stem tool, and
- repeating the above operations with each remaining one of said equipments at each remaining one of said respective locations.
An apparatus for the successive installations of substantially linear equipments within a soil comprising:
- (a) carrier means,
- (b) longitudinal displacement means including a mast,
- (c) an annular driving rotary head carried by the mast for rotation within both directions
- (d) a tubular stem helicoidal auger connected to said rotary head, for introduction within the soil,
- (e) means for feeding one of said equipments into the tubular stem auger through the annular driving rotary head,
- (f) means for controlling the rate of axial displacement and rotation of said tubular stem helicoidal auger whereby it permits a predetermined compaction or decompaction of the soil to be obtained around said one of said equipments while removing said tubular stem helicoidal auger.
