MANHOLE REHABILITATION METHOD AND MANHOLE REHABILITATION STRUCTURE
To provide a manhole rehabilitation method and a manhole rehabilitation structure applicable for rehabilitation work on an existing manhole that is connected to a middle-to-large diameter pile conduit (sewer) and has the lowermost part opened downward.SOLUTION: A manhole rehabilitation method comprises injection of mortar to a cloth mold form 15 through a tube 16 and injection of back filling material in a gap S between an inner peripheral surface of a vertical wall 11 and an outer peripheral surface of a cylindrical body 12 in a state that the cylindrical body 12 is kept hung in a manhole 10 as engaging parts 13a of a plurality of stoppers 13 attached on a part closer to an upper end opening 12a of an outer periphery of the cylindrical body 12 abuts an upper end part 11b of the vertical wall 11 positioned at an uppermost part of the manhole 10 when the cylindrical body 12 in a cylinder shape is inserted from an upper end opening 11a of the vertical wall 11 toward the inside of the manhole 10.SELECTED DRAWING: Figure 2
【課題】中大径管路（管渠）などに接続され、最下部分の下方が空洞状態となっている既設マンホールの更生工事において実施可能なマンホール更生工法及びマンホール更生構造を提供する。【解決手段】直壁１１の上端開口部１１ａからマンホール１０内に向かって円筒形の筒状体１２を挿入していくと、筒状体１２の外周の上端開口部１２ａ寄りの部分に取り付けられた複数のストッパ１３の係止部１３ａが、マンホール１０の最上部分に位置する直壁１１の上端部１１ｂに当接するので、筒状体１２はマンホール１０内で宙吊り状態に保持され、この状態において、チューブ１６を経由して布製型枠１５へのモルタルの注入や、直壁１１の内周面と筒状体１２の外周面との隙間Ｓへの裏込め材の注入などを行う。【選択図】図２
