Title:
PIPING LAYING TRENCH AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3566360
Kind Code:
B2
Abstract:
PURPOSE: To shorten a piping work period by maintaining higher efficiency and manpower saving for a work to construct a trench and lay piping.
CONSTITUTION: Piping is laid on racks 18 fitted to the side wall of a lower trench 12. The trench 12 is, then, suspended and laid on a foundation, thereby eliminating a piping work in the trench 12. Thereafter, the piping 20 is laid on suspension members 26 connected to the ceiling wall of an upper trench 22, and this upper trench 22 is lowered to be jointed to the lower trench 12. As a result, a trench construction work is completed, and the piping 20 does not need to be laid thereafter. Also, a piping work can be completed simply by jointing the piping 20 laid in every block.
