Abstract
PURPOSE:To concurrently solidify the ground consisting of different water- permeable layers by a method in which a packer is set in the aperture of the inner and outer tubes of a double tube having openings in its inner and outer tubes, and grout is injected into the ground by using the packer. CONSTITUTION:An outer tube 21 in which the outlet 25 of the tube wall 24 is covered with a rubber sleeve 26 is set in a pit formed in a ground 23. An inner tube 22 having a jet nozzle 28 in its tube wall 27 on the axially different position from the outlet 25 is inserted into the outer tube 21, and a packer 30 is set between the tubes 22 and 21 to form many spaces 31 surrounded by the tubes 22 and 21 and the packer 30. Grout is introduced into the tube 22 and injected from the nozzle 28 into the spaces 31. The grout expands the rubber sleeve 26 through the outlet 25, breaks a sleeve grout 32 injected between the tube 21 and the ground 23, and permeates into the ground 23.
