Abstract
PURPOSE: To uniformly inject chemicals into a wide range of ground at a low injection pressure by rotating an injection pipe whose diameter is made smaller at near the injected part in order to form inducing part which serves to form an induced injection space between the pipe and the bored wall.
CONSTITUTION: The diameter of an injection pipe body 1 adjacent to chemical injection ports 2 and 3 provided on the wall of the pipe is made smaller in order to form induction portions, so that induced injection spaces S1 and S2 are formed between the pipe and the bored wall to be eccentric with the pipe axis center O and positioned nearer towards the injection ports 2 and 3. When chemicals are injected while rotating the injection pipe 1, solidified or semisolidified chemicals filled in the spaces S1 and S2 are compressed in the eccentric portions. Since the injection ports 2 and 3 are positioned when the pressured is maximized, the compressive force is added to the injection pressure, so that a high pressure injection can be performed. The method is effective when a chemical having a gelation time of above 60 seconds is infiltratively injected into sandy ground or the like at a low pressure.
