Abstract
A method of forming a row of concrete piles in ground is disclosed wherein it is possible to position piles sufficiently close that additional concrete shoring on either side or between piles is unnecessary. A hole for a pile is first bored, the ground forming the hole is hardened and thereafter filled with concrete. This process is repeated for subsequently drilled holes until the row is completed. A drill is also disclosed which includes jet means to force ground hardening liquid under high pressure into the ground surrounding the hole. The jet means may be rotatably and/or axially moveable within the hole.
Claims12
A method for forming a continuous row of piles comprising the steps of:
- boring a first hole in the ground;
- hardening the ground surrounding said first hole by forcing a ground hardening liquid under high pressure into said ground surrounding said first hole;
- filling said first hole with mortar;
- boring a second hole adjacent said first hole;
- hardening the ground surrounding said second hole by forcing a ground hardening liquid under high pressure into said ground surrounding said second hole, a portion of the ground surrounding said first and second holes being common to both said holes;
- filling said second hole with mortar, and
- repeating said steps of forming said piles until a row of piles has been completed.
The method of forming a row of piles comprising the steps of:
- boring in sequence a row of holes;
- hardening the ground adjacent each hole after it has been bored by forcing a ground-hardening liquid under high pressure into said ground adjacent said hole;
- positioning each subsequent hole sufficiently close to the preceeding hole so that a portion of the hardened ground adjacent each hole is common to both holes, and
- filling each hole with mortar after the ground surrounding each hole has been hardened.
