U-GUTTER, CONSTRUCTION OF DRAIN PASSAGE USING GUTTER, AND U-GUTTER SUPPORT BED

摘要

PROBLEM TO BE SOLVED: To improve workability by a method wherein the respective bottom part of the right and left side walls of a U-gutter body are fixed at the mount part of a U-gutter support body and one of a plurality of lock parts different in height. SOLUTION: The bottom of one side wall 4 of a U-gutter body 1 is placed on a mount part 6 of a U-gutter support body 2. Thereafter, the bottom of the other side wall 3 of the U-gutter 1 is selectively fixed at a stair-form lock part 5 of a plurality of lock portions 10 arranged at the support body 2, and the U-gutter 1 is placed on the support body 2 in a state to be inclined at a desired angle. The U-gutter 1 is then placed on the support body 2 such that the bottom of the U-gutter 1 is brought into a horizontal state. Further, a space between the U-gutter 1 and the support body 2 is filled with concrete 8, and further, a proper cover body is arranged on a notch part 7 of the U gutter 1. This constitution easily and rapidly arranges the U-gutter on the road surface and the road side of a forest road where a gradient change is wide, whereby the occurrence of breakage of the U-gutter and a road surface is relieved and further, a repair cost is reduced.
