JOINT REINFORCEMENT STRUCTURE FOR MANHOLE PERIPHERAL WALL
PROBLEM TO BE SOLVED: To provide a joint reinforcement structure for a manhole peripheral wall formed by joining annular structure parts or blocks, the joint reinforcement structure preventing dislocation of the parts and impairment of a manhole function due to earthquake or other forms of ground change.SOLUTION: A structure is for reinforcing a joint P of a manhole peripheral wall 1 configured by vertically connecting a plurality of annular structure parts 1a, 1a with a connection member 2. The manhole peripheral wall 1 has a plurality of the circular arc-form connection members 2 provided along the joint P almost over an entire circumference, at a location covering the joint P between the annular structure parts 1a, 1a piled vertically. Each of the connection members 2 is fixed with a fixture 3 on the manhole peripheral wall 1 from an inner peripheral side, at locations above and below the joint P.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、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補強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，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１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同士の継目Ｐを跨ぐ箇所に、複数の円弧状をなす連結部材２を継目Ｐに沿ってほぼ全周に配置するとともに、継目Ｐを挟んだ上側と下側のマンホール周壁１に対して各連結部材２の内周側から固定具３で固定してあることを特徴とする。【選択図】 図１
