Deep foundation pit inner support system bottom-layer supporting beam early dismounting structure and construction method
The invention discloses a deep foundation pit inner support system bottom-layer supporting beam early dismounting structure and a construction method. The construction method comprises the steps thata cushion layer is laid at the bottom of a foundation pit; basement bottom plates and a post-cast strip on the cushion layer are arranged at intervals, force transmitting structural steel is arrangedin the extending direction of the post-cast strip and sandwiched between the basement bottom plates on the two sides of the post-cast strip, and plain concrete is arranged between the basement bottomplates and a foundation pit protection wall. The deep foundation pit inner support system bottom-layer supporting beam early dismounting structure is convenient to install and economical and practical, and material taking is convenient; and meanwhile, the floor rigidity is enhanced, the foundation pit horizontal load is effectively transmitted, the construction period is shortened, cost is saved,and obvious economic benefits are achieved.
本发明公开了一种深基坑内支撑体系底层支撑梁早拆结构及施工方法，包括在基坑底部铺设垫层；以及在垫层上有地下室底板与后浇带间隔设置，沿后浇带延伸方向排布传力型钢，其夹设于后浇带两侧的地下室底板之间，所述地下室底板与基坑护壁之间设置有素混凝土。本发明安装方便，取材便利，经济实用；同时增强楼板刚度，有效传递基坑水平荷载，缩短工期，节约成本，具有显著经济效益。
