PIPE LINE LAYING METHOD, TIMBERING METHOD, AND TIMBERING ASSEMBLING BODY

摘要

PROBLEM TO BE SOLVED: To enable a pipe for laying to be easily arranged in a trench by feeding the pipe in the longitudinal direction of the pipe while suspending the pipe by a chain roller, and by lowering the pipe in the burying trench. SOLUTION: After rollers 40 are installed and portal cranes 50 in which chain rollers 60 are suspended are installed, a pipe 1 is placed on the rollers 40 by using the cranes, a wire 3 whose one end is connected to the pipe 1 is pulled by using a monkey winch 4, and the pipe 1 is moved while being supported by the chain rollers 60. The pipe 1 is moved until the whole pipe 1 is supported by the chain rollers 60, and the pipe 1 is lowered in a trench 10. Therefore, the pipe 1 can be arranged in the trench 10 without many man- hours that a strut is detached and again set like in the conventional method.
