JOINT STRUCTURE OF MANHOLE PERIPHERAL WALL
PROBLEM TO BE SOLVED: To provide a joint structure of a manhole peripheral wall, applicable even in an existing manhole without displacing respective parts of a manhole dividedly constituted by an annular structure and a block to a ground change such as an earthquake, and without impairing the function of the manhole even in an emergency without corroding even when exposed to gas and a chemical in the manhole, in the present invention.SOLUTION: In a structure for reinforcing a joint P of a manhole peripheral wall for constituting the manhole peripheral wall 1 by vertically connecting a plurality of annular structures 1a by a connection member 2, a plurality of connection members 2 are arranged at an interval along the joint P in a place of straddling the joint P on the inner peripheral part side of the manhole peripheral wall 1 of mutual respective vertically stacked annular structures 1a and 1a, and cushioning members 4a and 4b are provided between the connection member 2 and the manhole peripheral wall 1, and the respective connection members 2 are fixed by a fixture 3 to an inner peripheral part of the manhole peripheral wall 1 on the upper side and the lower side for sandwiching the joint P, and at least the connection member 2 is formed of a raw material having chemical resistance and gas resistance.SELECTED DRAWING: Figure 1
【課題】 本発明は、地震等の地盤変化に対して環状構造物やブロック等で分割構成されるマンホールの各部がずれることなく、しかも、既設マンホールにおいても適用することができ、さらに、マンホール内のガスや薬品に晒されても腐食せず、有事にあってもマンホールの機能が損なわれないマンホール周壁の継目構造を提供することにある。【解決手段】 複数の環状構造物１ａを連結部材２で上下に連結してマンホール周壁１を構成するマンホール周壁の継目Ｐを補強する構造であって、上下に積み上げた各環状構造物１ａ，１ａ同士のマンホール周壁１内周部側の継目Ｐを跨ぐ箇所に、複数の連結部材２を継目Ｐに沿って間隔をあけて配置するとともに、連結部材２とマンホール周壁１の間に緩衝部材４ａ，４ｂを設け、継目Ｐを挟んだ上側と下側のマンホール周壁１の内周部に対して各連結部材２を固定具３で固定してあり、少なくとも連結部材２は、耐薬品性及び耐ガス性を有する素材で形成してあることを特徴とする。【選択図】 図１
