<p>PURPOSE:To lay a pipe with good accuracy by a method in which a U-shaped constituent part of pipe and a box-like material are orderly set in a trench excavated while filling it with a stabilizer liquid and fixed inside of the trench with the solidification of the stabilizer liquid, and then the box-like material is removed out. CONSTITUTION:A constituent part 10 and a pipe and a box-like material 14 are hung down in a trench 12 excavated while filling it with a stabilizer liquid through a rod 16 fitted with a beam 26. The part 10 and the material 14 are fixed inside of the trench 12 with solidification of the stabilizer liquid or of a self-hardening substance replaced with the stabilizer liquid, and then the box- like material 14 is removed out. Since the intrusion of the stabilizer liquid into the constituent part can be prevented, the pipe can be laid with good accuracy.</p> |
