<p>PROBLEM TO BE SOLVED: To provide an environment-friendly technique such that when a ditch cover structure is installed in a water passage ditch (gutter, crossing gutter) to cover the opening, the height and attitude of the ditch cover structure can be easily and accurately adjusted in a short time, and shortening of the construction period and reduction in cost can be achieved by providing an injection space for connection material and functions as a joint bar (reinforcing bar) and a safety device.SOLUTION: A ditch cover structure has a ditch cover body 2p, 4p, 6p, or 8p installed to cover the opening of a water passage ditch, and a height and attitude adjustment mechanism 24 which levels a surface S1 of the ditch cover body to the surface of a road by adjusting heights and attitudes to an upper part Up of the water passage ditch. The height and attitude adjustment mechanism has an adjustment hole 24h having a first screw part Fs1 formed and an adjustment bolt 24t having a second screw part Fs2 screwed with the first screw part, and the height and attitude of a ditch cover body are adjusted by rotating the adjustment bolt to project or sinking the tip 24b thereof from and into the reverse surface S2 of the ditch body.</p> |
