Continuous open caisson type subway entrance and exit structure and construction method
The continuous open caisson type subway entrance and exit structure structurally comprises a plurality of open caissons and tenon type connecting walls used for connecting the open caissons, and the open caissons comprise the first open caisson and the second open caisson which serve as channel spaces and the third open caisson and the fourth open caisson which are used for providing entrance and exit stair construction spaces. Each open caisson comprises a blade foot, a first section of well wall and a second section of well wall which are sequentially connected from bottom to top; open caisson bottom beams are arranged at the bottom of the open caisson; a concrete cushion layer is laid on the first open caisson bottom beam, a bottom plate is arranged on the concrete cushion layer, and a top plate ring beam is arranged on the top of the first section of well wall. The first open caisson and the second open caisson are longitudinally arranged front and The first open caisson, the second open caisson, the third open caisson and the fourth open caisson are communicated through well wall holes The construction efficiency of the entrance and exit is effectively improved, and the influence of station construction on the surrounding environment is reduced.
本发明公开了一种连续沉井式地铁出入口结构及施工方法，其结构包括多个沉井以及用于连接沉井的凸榫式连接墙，沉井包括用作通道空间的第一沉井和第二沉井以及用于提供出入口楼梯施工空间的第三沉井和第四沉井，每个沉井均包括由下往上依次连接的刃脚、第一节井壁以及第二节井壁；沉井的底部布设有沉井底梁；第一沉井底梁上方铺设有一层混凝土垫层，混凝土垫层上方设有底板，第一节井壁的顶部设有顶板环梁；第一沉井与第二沉井纵向前后设置；第一沉井、第二沉井、第三沉井以及第四沉井通过井壁开孔连通；本发明有效提高出入口的施工效率，降低车站施工对周边环境的影响。
