CONSTRUCTION METHOD FOR MANHOLE REHABILITATION STRUCTURE
To provide a construction method for a manhole rehabilitation structure in which a manhole for rehabilitation is installed inside an existing manhole, which can transmit a vertical load acting on a lid body from above to the manhole for rehabilitation.SOLUTION: A construction method for a manhole rehabilitation structure in which a manhole 12 for rehabilitation is installed inside an existing manhole 20 having a straight wall part 21 and an inclined wall part 22 includes the steps of: installing the manhole for rehabilitation inside the existing manhole so that an upper end face 12a thereof has a height equal to or higher than an upper end face of the inclined wall part, in a state where the manhole for rehabilitation is kept in close contact with the straight wall part and the inclined wall part; installing an annular load transmission member 30 so as to overlap the upper end face of the inclined wall part of the existing manhole and the upper end face of the manhole for rehabilitation; and installing a lid body 16 through a lid body receiving frame 18 having an inner diameter substantially coinciding with the inner diameter of the existing manhole.SELECTED DRAWING: Figure 1
【課題】既設マンホールの内側に、更生用マンホールを設置するマンホール更生構造の施工方法において、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更生構造の施工方法を提供すること。【解決手段】直壁部２１と斜壁部２２とを有する既設マンホール２０の内側に、更生用マンホール１２を設置するマンホール更生構造の施工方法であって、前記既設マンホールの内側に、前記更生用マンホールを前記直壁部及び前記斜壁部に密着させた状態で、かつ前記更生用マンホールの上端面１２ａが前記斜壁部の上端面以上の高さとなるように設置する工程と、前記既設マンホールの前記斜壁部の上端面と、前記更生用マンホールの上端面とに重なるように、環状の荷重伝達部材３０を設置する工程と、前記既設マンホールの内径とほぼ一致する内径を有する蓋体受枠１８を介して、蓋体１６を設置する工程と、を含むことを特徴とする。【選択図】図１
