ABSTRACT:
A foundation improvement process comprising providing a first nozzle, a third nozzle, and a second nozzle opened up encircling the first nozzle at the side wall of a lower portion of an injection rod, at the same time providing a diffusion nozzle at an intermediate portion between the first and third nozzles, forming a curtain with a high pressure water jetting from this diffusion nozzle, providing a partition wall between hardening agent jetting from the third nozzle and an air lift portion by means of a fresh water and air jetting from the first and second nozzles by using this water curtain, thereby preventing the raising of the injected hardening agent for performing a sure improvement of a foundation, and at the same time preventing waste of the hardening agent.
