ABSTRACT:
The invention is related to a process according to which at the end of reinforcement bars inserted in a pile a nearly cylindrical and elongated chamber is inserted in the ground, said chamber having rigid impervious walls as to the fluids tending to enter from the outside, while when injecting cement grout into said chamber through appropriate tubes, the side walls will break and allow for grout expansion into the ground. The injection operation can be repeated for several times after as many scavengings or washings of the chamber.
