Abstract

A device for forming improved earth ground, which comprises forming sharpened holes on the earth ground, using injection rod of hardening agent to inject the hardening agent which will improve the earth ground at high pressure, moving the injection rod of hardening agent along the longitudinal axis so as to improve the earth ground; which is characterized in that: the injection rod of hardening agent is equipped with external pipe and multiple piping installed in the external pipe, in which the piping can rotate corresponding to the external pipe and the external pipe can bescrewed together by the screw section at the terminal; during working, adriving device rotates the injection rod of the hardening agent toward aspecific direction which will tighten the external pipe.
