Abstract
PURPOSE: To enable full mixing of two kinds of grout and also prevent the concretion of the grout in tubes by a method wherein an outer tube for injecting the grout and an inner tube are arranged concentrically and a bock-flow preventing device formed of an elastic circular body is provided on the outer-peripheral wall of each tube.
CONSTITUTION: Liquid A and liquid B both comprising the grout for improving the ground, used through mixing of the two, are pressed in an outer tube 1 and an inner tube 5, respectively. The liquid A penetrates into the intermediate part between an intermediate tube 2 and the inner tube 5 and advances from a liquid-A injecting orifice 3 into the intermediate part between the outer tube 1 and the intermediate tube 2, expanding an elastic circular body 4 in the direction of width, and further into the lower part of the outer tube 1. The liquid B advances from the inner tube 5 into the lower part of the intermediate tube 2 and further, expanding an elastic circular body 8 in the direction of width, penetrates from a liquid-B injecting orifice 7 into the outer tube 1, where it is mixed with the liquid A and stirred sufficiently. Then, the mixed grout is injected into the ground on the outer periphery and improves the ground through setting. By this, the back flow can be prevented and the concretion in the tubes can also be prevented.
