METHOD AND INSERT FOR REPAIRING MANHOLE RECEIVING FRAME
PROBLEM TO BE SOLVED: To provide a method for repairing a manhole receiving frame which does not require replacement of a manhole cover or a manhole receiving frame by making it possible to repair a bolt hole for a bolt fixing the manhole cover to the manhole receiving frame.SOLUTION: A method for repairing a manhole receiving frame 101 is for the manhole receiving frame 101 which is annular, whose circumference is provided with a protrusion 101a, in which a bolt hole 101b is formed, and on which a manhole cover is mounted. A mounting hole 101c with a larger diameter than that of the bolt hole 101b is formed coaxially with the bolt hole 101b, and an insert 1 for repairing is mounted on the mounting hole 101c. The insert 1 for repairing comprises: a body portion 2 formed in a cylindrical shape; a stopper portion 3 preventing the body portion 2 from being inserted under a surface of the manhole receiving frame 101; and a rotation stopping portion 4 preventing the body portion 2 from rotating around a shaft center.SELECTED DRAWING: Figure 3
【課題】マンホール蓋をマンホール受枠に固定しているボルト用のボルト孔の改修を可能にすることで、マンホール蓋及びマンホール受枠の取り替えを不要にするマンホール受枠の改修方法を提供する。【解決手段】マンホール受枠１０１の改修方法は、環状で周縁に突出部１０１ａが設けられてボルト孔１０１ｂが形成され、マンホール蓋が装着されるマンホール受枠１０１の改修方法であり、ボルト孔１０１ｂよりも大径の装着孔１０１ｃをボルト孔１０１ｂと同軸に形成し、改修用インサート１を装着孔１０１ｃに装着する。改修用インサート１は、円筒状に形成された本体部２と、本体部２がマンホール受枠１０１の表面よりも深く挿入することを防止するストッパ部３と、本体部２が軸心周りに回転するのを防止する回り止め部４とを備えている。【選択図】 図３
