摘要

PROBLEM TO BE SOLVED: To provide a pipe member for forming a water pass in which a water pass making underground water to flow can be easily formed without need of a special design and a stopper plate, the underground continuous wall having the water pass, and a water pass forming method of the underground continuous wall.;SOLUTION: The opening 2b of a pipe 1b opening to the left under side of the water pass forming pipe member 1 and the opening 2d of a pipe 1d opening to the right under side of the member are closed with sealing materials. The water pass forming pipe member 1 is immersed in the soil cement 10 of the underground continuous wall. After the soil cement 10 has lost its fluidity, excavators are inserted into the pipe 1a opening to the right upper side and the pipe 1c opening to the right upper side and remove the sealing materials fitted to the pipe 1b opening to the right under side and the pipe 1d opening to the left under side, to form the water pass formed of the pipe 1b opening to the left under side, the pipe 1d opening to the right under side, and a horizontal pipe 4 installed between these pipes.;COPYRIGHT: (C)2004,JPO
