MANHOLE REPAIRING METHOD AND MANHOLE REPAIRING STRUCTURE
PROBLEM TO BE SOLVED: To provide a manhole repairing method and a manhole repairing structure with which a manhole having an excellent durability may be reconstructed with an excellent workability for short construction period.SOLUTION: A manhole repairing structure 300 is constructed by a manhole repairing method, in which the ground around an existing manhole 100 is dog and a part equivalent or over an inclined wall and invert in the existing manhole 100 are removed, a new bottom plate 201 is established on an existing bottom plate 101, a pipe attaching wall 202 and a straight wall 205 of a new manhole 200 are inserted into inner section of the existing manhole 100 and connected in a standing manner, back-filling material R is injected into a gap between inner peripheral surface of the existing manhole 100 and peripheral surface of the new manhole 200, an invert 211 is established on the new bottom plate 201, an inclined wall 206 and an adjustment ring 207 are attached onto the straight wall 205 of the new manhole, periphery of the inclined wall 206 is filled up, a receiving frame 209 and an iron lid 210 are attached on the adjustment ring 207, and periphery thereof is paved.SELECTED DRAWING: Figure 11
【課題】作業性が良好で、工期が短く、耐久性に優れたマンホールを再構築することができるマンホール改修工法及びマンホール改修構造を提供する。【解決手段】マンホール改修構造３００は、既設マンホール１００の周りを掘削して斜壁以上の部分及び既設マンホール１００内のインバートを撤去し、既設底版１０１上に新設底版２０１を設置し、新設マンホール２００の管取付壁２０２及び直壁２０５を既設マンホール１００の内部に挿入して直立状に接続し、既設マンホール１００内周面と新設マンホール２００外周面との隙間に裏込め材Ｒを注入し、新設底版２０１上にインバート２１１を設置し、新設マンホールの直壁２０５上に斜壁２０６、調整リング２０７を取り付け、斜壁２０６の周囲を埋め戻し、調整リング２０７上に受枠２０９及び鉄蓋２１０を取り付け、その周囲を舗装するマンホール改修工法によって構築されている。【選択図】図１１
