Title:
CONSTRUCTION METHOD OF UNDERGROUND CUT-OFF WALL
Document Type and Number:
Japanese Patent JP3023236
Kind Code:
B
Abstract:
PURPOSE: To eliminate the deterioration of stabilized liquid to be used and at the same time, to build a cut-off sheet, to enable the coupling work and to construct a cut-off wall excellent in execution efficiency and cut-off efficiency.
CONSTITUTION: An excavated channel 6 is formed in the ground while using wall stabilized liquid 5, and a bag body of an impermeable fluid sheet divided into a plurality of cells 1A-1F by partition wall members 1a-1e having the length substantially equivalent to the depth of the channel against the excavated channel 6 and arranging the inside thereof in the direction of the width of the channel is built in a state of contraction. After that, fillers are successively injected into the cells of the bag body 1, and a cut-off wall W covered with the impermeable fluid sheet is constructed in the excavated channel 6.
