Abstract
PURPOSE: To inject the grout having differet gel time by a method wherein hardening liquids with different gel time are separated and put in two tanks and the supply quantity of both hardening liquids is controlled by a valve in a grout supply device which is struck in and made to reach the aimed ground.
CONSTITUTION: A grout supply device A is composed of a grout tank 1 which consists of a tank 1a containing an accelerating liquid C1, a tank 1b containing a hardening liquid C2 with short gel time and a tank 1c containing a hardening liquid C3 with long gel time, and of valves 6W8, supply routes D and E, pumps 2 and 4, a meter 15, pressure-supervising devices 3 and 5, etc. And, a grout-injecting device B is constituted by a boring machine 16 which strikes an outer pipe 11 into the ground G, an injector 12 built in the outer pipe 11, etc. In the device, by controlling the valves 6 and 7 in particular manually or automatically, the hardening liquid C2 or C3 solely, or the grout of various kind prepared by compounding both liquids to have the desired gel time, can be supplied freely to the injector 12 in the outer pipe 11.
