Abstract
PURPOSE: To provide a method of injecting solidifying agents capable of preventing loss due to dilution by under-ground water as well as solidifying any kind of agents at a desired position under the ground.
CONSTITUTION: In case a tip portion of an injecting rod is introduced to a predetermined depth under the ground, a boring machine is utilized and the rod is proceeded blowing water or water containing bentonite mud, pressurized by an injection pump, through a metal crown C-1 at a forward end of a rotating double pipe A equipped with a holoow rod B and a rod portion C for a non-return valve. In this case, a piston member B-2 is located at a position to close discharging ports B-4 for agents by a spring B-3, and the liquid for drilling alone is flown smoothly to the metal crown C-1. When the discharging ports B-4 are arrived at the predetermined depth, forced input of the liquid for drilling is stopped and a valve member C-2 is closed by pressurized under-ground water, and thereafter, a steel ball B-5 is thrown into the pipe and the piston member B-2 is moved downwardly, thereby, the discharging ports B-4 are opened and the agent may be discharged therethrough.
