Foundation pit supporting structure in deep and thick sludge and construction method of foundation pit supporting structure
The invention relates to a foundation pit supporting structure in deep and thick sludge and a construction method thereof.The foundation pit supporting structure comprises a plurality of sets of stainless steel plates and supporting structures installed in cooperation with the stainless steel plates, the stainless steel plates are vertically inserted into a foundation pit, and the heads and the tails of the adjacent stainless steel plates are laid in a sealed mode; the vertical end faces of the sides, away from the foundation pit, of the stainless steel plates abut against the side wall of the foundation pit. The vertical edges of the two sides of each set of stainless steel plates are arranged in a penetrating mode, first steel chisels are horizontally inserted into the vertical edges of the two sides of each set of stainless steel plates, each supporting structure comprises a reinforcing plate and an inclined rod hinged to the reinforcing plate, and the first steel chisels on the two adjacent sets of stainless steel plates penetrate through the reinforcing plates and are in threaded connection with fastening nuts; the inclined lower end of the inclined rod is integrally connected with a fixing plate, and a second steel chisel is vertically connected to the fixing plate in an inserted mode. According to the foundation pit supporting structure, supporting of all sets of stainless steel plates is achieved, and the occurrence probability of soil body slippage and foundation pit instability is reduced.
本申请涉及一种深厚淤泥中的基坑支护结构及其施工方法，其包括若干组不锈钢钢板及与各组不锈钢钢板配合安装的支撑结构，各组所述不锈钢钢板竖直插接在基坑内部，相邻各组所述不锈钢钢板的首尾密封铺贴，各组所述不锈钢钢板背离所述基坑的一侧竖直端面与基坑的侧壁抵接；各组所述不锈钢钢板的两侧竖直边沿上均贯穿开孔设置并水平插接有第一钢钎，所述支撑结构包括加强板及与所述加强杆铰接的斜杆，相邻两组所述不锈钢钢板上的各组所述第一钢钎贯穿所述加强板并螺纹连接有紧固螺母，所述斜杆的倾斜下端部一体连接有固定板，所述固定板上竖直插接有第二钢钎。本申请实现了对各组不锈钢钢板的支撑，降低了土体发生滑移及基坑失稳的发生概率。
