REPAIR METHOD OF SIDE DITCH COVER

PROBLEM TO BE SOLVED: To provide a method capable of easily and properly adjusting a level of a new side ditch cover, when repairing a side ditch cover.SOLUTION: In a repair method of the side ditch cover supported by a left cover receiving part and a right cover receiving part formed by stepping down on the respective upper part inside of opposed left sidewall and right sidewall of an existing side ditch, an existing side ditch cover is removed, and the new side ditch cover thinner in a thickness and narrower in a width than the existing side ditch cover is prepared, and a suspension tool crosslinked between upper end surfaces of the opposed left-right sidewalls of the existing side ditch, is installed in a plurality at an interval along the longitudinal direction on an upper surface of the new side ditch cover, and while an upper surface of the new side ditch cover and an upper end surface of the left-right sidewalls are made flush by the respective suspension tools, the new side ditch cover is suspended and supported between rising surfaces of the left and right cover receiving parts, and a filler is filled in a space defined between a left end surface of the new side ditch cover of a suspending state and the rising surface of the left cover receiving part and a space defined between a right end surface of the new side ditch cover and the rising surface of the right cover receiving part, and the new side ditch cover is fixed. 【課題】 側溝蓋の改修において、新設側溝蓋のレベル調整を容易且つ適切に行うことができる工法の提供。【解決手段】 既設側溝の対向する左側壁及び右側壁の各上部内側に断落ちして形成された左蓋受部及び右蓋受部により支持される側溝蓋の改修工法であって、既設側溝蓋を除去し、該既設側溝蓋よりも薄厚且つ幅狭の新設側溝蓋を用意し、既設側溝の上記対向する左右側壁の上端面間に架橋する吊り下げ治具を上記新設側溝蓋の上面に長手方向に沿って間隔を置いて複数取り付け、上記各吊り下げ治具により上記新設側溝蓋の上面を上記左右側壁の上端面と面一にしつつ当該新設側溝蓋を上記左右蓋受部の立ち上がり面間で吊り下げて支持し、該吊り下げ状態の新設側溝蓋の左端面と上記左蓋受部の立ち上がり面間に画成される空間及び同新設側溝蓋の右端面と上記右蓋受部の立ち上がり面間に画成される空間に充填材を充填し当該新設側溝蓋を固定することを特徴とする。【選択図】 図５
