Document Type and Number:
Japanese Patent JPH08296236
Kind Code:
A
Abstract:
PURPOSE: To provide a cut-off of water which does not adversely affect a peripheral structure, and is easily executed at low cost.
CONSTITUTION: An injection pipe 11 is provided near a sheathing wall 3 in such a manner that the tip of the injection pipe 11 reaches near a leakage part 7. A water absorbing high molecular polymer material 13 is poured into the injection pipe 11. The water absorbing high molecular polymer material 13 extruded to the tip of the injection pipe 11 reacts with underground water, rapidly absorbs water and swells, and blocks the leakage part 7 to cut off water.
