<p><P>PROBLEM TO BE SOLVED: To provide a water channel structural member enabling easy setting of gradient, easy adjustment of the set gradient, and reduction in the amount of a filler. <P>SOLUTION: This water channel structural member 1 comprises a gutter-like invert part 2 upwardly opened and allowing sewage to flow therein, forms a novel water channel in a pipeline P buried in the ground, and comprises, as a support part, a plurality of extensible leg parts 10 having lower parts in contact with the inner surface of the pipeline. The leg part 10 is formed of a center shaft part 12 on the inner periphery and a fixed pipe part 11 on the outer periphery, a hexagon hole 13 is formed at the upper end of the center shaft part, and the vertical position of the water channel structural member can be adjusted by inserting a hexagon socket head spanner S from the upper side therein and rotating the center shaft part. The leg part 10 is so formed that the hexagon hole 13 is exposed upward as an adjustment part for adjusting the vertical position thereof at a position where the leg part can be adjusted after installation, and the center shaft part is rotated from the upper side to adjust the vertical position of the water channel structural member. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
