Abstract

PURPOSE: To coagulate soft or water-leaking ground or stopping water leakage by combining instantly-coagulantory suspension type and solution type grouts using a multiple pipe for making packer effect and permeation effect respectively.
CONSTITUTION: Aqueous solution of water glass is supplied through a multi-pipe duct I', the aqueous reactor solution containing the cement which gels when getting together with the aqueous solution of water glass through a duct II'. A packer is formed the instantly-coaqulatory suspension type grout obtained making junction of the aqueous solutions of water glass and of reactant around an injection pipe to reinforce the ground and to bind injection object range. Next, the feed of the mixture liquid through the duct II' is stopped, and the solution type grout having gotten together with the mixture liquid is injected into the ground and let in fine soil particles into which the suspension type grout has been unable to penetrate by breaking the packer to reinforce injection range and to give watertight property.
