INSTALLATION METHOD OF MANHOLE FRAME
PROBLEM TO BE SOLVED: To provide an installation method of a manhole frame that prevents cracking and damaging in a boundary portion between a pavement material filled around the manhole frame and a pavement material of an ordinary paved road.SOLUTION: An installation method of a manhole frame includes the following steps for: cylindrically cutting an area of a prescribed diameter φ1 in a paved layer 4 that includes an area for installing a manhole frame 3; cylindrically cutting only a surface part 43 of the paved layer 4, at a diameter φ2 greater than the prescribed diameter φ1; removing the paved layer 4 in the area of the prescribed diameter φ1 and removing the surface part 43 in the surrounding area with the diameter φ2 greater than the prescribed diameter, thus forming a space surrounded by a stepped peripheral wall; and installing the manhole frame 3 at a roughly same height with a paved road surface, on a manhole base wall 1 exposed in the space.SELECTED DRAWING: Figure 10
【課題】マンホール枠周囲に充填された舗装材と一般舗装路の舗装材との間の境界部分に亀裂や破損を生じないマンホール枠の設置工法を提供する。【解決手段】マンホール枠３を設置する領域を含む舗装層４の所定径φ１の領域を円筒状に切断する工程と、舗装層４の表層部４３のみを、所定径φ１よりも大きい径φ２で円筒状に切断する工程と、所定径φ１の領域内で前記舗装層４を除去するとともにその周囲の所定径よりも大きい径φ２の領域内で表層部４３を除去して段付きの周壁で囲まれた空間を形成する工程と、空間内に露出したマンホール基壁１上にマンホール枠３を舗装路面と略同一高さに設置する工程とを備える。【選択図】 図１０
