Octagonal working pit supporting member and mounting and construction method thereof
The invention discloses an octagonal working pit supporting member and a mounting and construction method thereof. The octagonal working pit supporting member comprises an octagonal working pit protection wall supporting member formed by butt joint, and a frame-shaped plate and a straight plate are connected through symmetrically distributed H-shaped steel cross braces; a working pit protection wall comprises an inner layer steel plate and an outer layer steel plate which are provided with steel plate stiffening ribs, and interlayer connecting pieces connected with adjacent interlayer working pit protection walls are arranged at the bottom of the working pit protection wall; and the H-shaped steel cross braces are connected with the working pit protection wall, the adjacent octagonal supporting members are connected through the interlayer connecting pieces, and pipe jacking or directional drilling working pit layer-by-layer excavation and reverse disassembly and recovery of the excavated octagonal supporting members are implemented. The supporting structure of the working pit can be excavated downwards from the ground in a layered mode, supporting members are recycled in a reverse layered mode, waste is reduced, accident risks such as difficult sinking, sudden sinking and inclined sinking in the construction process are avoided, and the octagonal working pit supporting member has the advantages of being repeatedly used, saving space, reducing cost, reducing energy consumption and being environmentally friendly.
本发明公开了一种八边形工作坑支护构件及其安装施工方法，包括由对接构成八边形工作坑护壁支护构件，框型板和直板通过对称分布的H型钢横撑连接；工作坑护壁包括设有钢板加劲肋的内、外两层钢板，工作坑护壁底部设有与相邻层间工作坑护壁相接的层间连接件；通过H型钢横撑连接工作坑护壁，通过层间连接件连接相邻八边形支护构件，实施顶管或定向钻工作坑层层开挖，以及开挖后的八边形支护构件的逆向拆卸回收。该工作坑的支护结构能够从地面分层向下开挖，逆向分层回收支护构件，减少浪费，避免施工中发生难沉、突沉、偏沉等事故风险，具有重复利用、节省空间、降低成本、减少能耗、绿色环保的优点。
