PURPOSE:To prevent the leak of water by a method in which a water-proof pipe and a hose are provided in a space formed in the water leak portion of a concrete wall, and concrete is placed there and even on a stopper water-tightly attached to the water-proof pipe. CONSTITUTION:A defective portion responsible for water leakage of a concrete wall 1 is cut off to form a space 2, and a through hole 16 is drilled there. A water-proof pipe 6 of a length L1 is set in the space 2, a hose 3 is connected to the pipe 6, and ground water on the outside of the wall 1 is drained. The water- proof pipe 6 portion connected with the hose 3 is removed out, and concrete is placed in the space 2 to bury the pipe 6. After the concrete is cured, the hose 3 is removed out, a stopper 13 is water-tightly attached to the pipe 6 and fixed, and the remaining space 2 is filled with concrete 17. Ground water can thus be drained through the pipe 6, and the leakage of water can be prevented by the stopper 13 attached to the pipe 6. |
