Abstract
PURPOSE: To exactly solidify and improve the ground while keeping a grout-injecting region under a restraint condition by injecting plural kinds of grouts having different permeabilities into the ground from a multiple injection tube.
CONSTITUTION: An injection tube is penetrated into soft ground and a grout having bad permeability is injected into the soft ground from the pathway I of an outer tube 1 to form a hardened seal D having a packing effect in an aperture between the injection tube and the ground. Then, a grout having a good permeability is injected from the lower part of an inner tube 2 not covered with the outer tube 1. The operations are repeated while pulling up the injection tube in such a way as to form a restraint block in which the hardened grout part E having good permeability is surrounded with the hardened grout part D of bad permeability.
