Foundation pit supporting system
The invention relates to a foundation pit supporting system. After the temporary supporting plate is drawn out, sandy soil located on the upper portion of the temporary supporting plate and close to the side wall of the foundation pit flows towards the position between the bottom supporting plate and the fixed supporting plate and buries the fixing pipes and the folding spring pieces. That is to say, most of the gap between the fixing pipe and the folding spring piece is filled with sandy soil. Viscous slurry is output to the sandy soil through the output hole of the fixed pipe. Then the boltsare loosened to release the fixed pipe, and the surface of the fixed pipe is coated with the viscous slurry after the viscous slurry is output, so that a lubricating effect can be achieved, and the fixed pipe can be conveniently pulled out of sandy soil and the fixed supporting plate. After the fixing pipe is pulled out of the fixing supporting plate, the folding spring pieces are released, and the folding state is rapidly restored so that sandy soil located between the folding spring pieces can be clamped. Therefore, the strength and density of the sandy soil between the folding spring pieces can be enhanced. Meanwhile, the adhesive slurry can also play a role in adhering sandy soil and increasing the adhesive force between sandy soil particles.
本申请涉及一种基坑支护系统。当将临时支护板抽出后，位于临时支护板上部靠近基坑侧壁的沙土朝向底部支护板和固定支护板之间流动并掩埋固定管和折叠弹簧片。即在固定管和折叠弹簧片之间的缝隙中大部分填充了沙土。此时通过固定管的输出孔向沙土输出粘浆。然后松动螺栓以释放固定管，刚输出粘浆后，粘浆涂覆在固定管的表面，可以起到润滑的作用，以便于将固定管从沙土和固定支护板中抽出。固定管从固定支护板抽出后，折叠弹簧片被释放，并迅速恢复折叠的状态，以夹紧位于折叠弹簧片之间的沙土。因此可以增强在折叠弹簧片之间的沙土的强度和密度。同时，粘浆还可以起到粘接沙土，增加沙土粒之间的粘附力的作用。
