Abstract

PURPOSE: To make the grout permeate and distribute evely by a method wherein an injector is let out from the inside of an outer pipe inserted in the ground and the grout is injected through a space formed between the injector and the surface of the hole of the ground.
CONSTITUTION: After boring is made down to the fixed depth by a bit 21 in such a state that an injector 5 is backed in an outer pipe 4, the outer pipe 4 is retreated by the sectional length L1. Next, an accelerating liquid and a hardening liquid are supplied under high pressure from a grout-supplying device not shown in the figure through liquid supply routes 7 and 8, respectively. Then, the injecter 5, being given the high pressure in the liquid supply route 7, is let out momentarily into the hole G1 of the ground, as shown in the figure. When the letting-out of the injector 5 being completed, the hole of a valve 19a is opened and the above liquids are mixed in the liquid route 9 and jetted out into the hole G1, improving the sectional length L1. Then, the supply of the grout is stopped, another section of the ground is bored, and such a process is repeated, thereby the deep ground being improved.
