MANHOLE RENOVATION STRUCTURE
To provide a manhole renovation structure with a cylindrical renovation manhole installed inside an existing manhole, allowing to transmit a vertical load applied to a lid body from the upper side to the renovation manhole.SOLUTION: A manhole renovation structure 10 has a cylindrical renovation manhole 12 with a predetermined thickness installed inside a cylindrical existing manhole 20 with a predetermined thickness. The structure has an annular load transmission member 30 which is provided between a lid body 16 closing an upper opening of the existing manhole 20 and the renovation manhole 12, and is overlapped on both of an upper end face 20a of the existing manhole 20 and an upper end face 12a of the renovation manhole 12, so that a vertical load transmitted via the lid body 16 is transmitted to at least an upper end face of the renovation manhole 12.SELECTED DRAWING: Figure 1
【課題】既設マンホールの内側に、筒状の更生用マンホールを設置したマンホールの更生構造において、蓋体に作用する上方からの垂直荷重を更生用マンホールに伝達することが可能なマンホールの更生構造を提供すること。【解決手段】所定厚さの筒状に形成されている既設マンホール２０の内側に設置された所定厚さの筒状の更生用マンホール１２を備えたマンホール更生構造１０において、既設マンホール２０の上部開口を閉塞する蓋体１６と、更生用マンホール１２との間に設けられ、蓋体１６を介して伝達される垂直方向の荷重が少なくとも更生用マンホール１２の上端面に伝達されるように、既設マンホール２０の上端面２０ａ及び更生用マンホール１２の上端面１２ａの双方に重ねられた環状の荷重伝達部材３０を備えた。【選択図】図１
