Foundation pit underground diaphragm wall deformation adjusting and supporting structure and construction method thereof
The invention discloses a foundation pit underground diaphragm wall deformation adjusting and supporting structure and a construction method thereof. A backing block, a sliding block, a jack and a loading block are arranged in an enclosing purlin groove hole. An arc-shaped groove I and a plurality of fixing holes I which are formed in the radial direction are formed in the backing block; the sliding block comprises an arc surface and a plane, and a plurality of second fixing holes are formed in the sliding block in the radial direction of the arc surface at intervals; the sliding block can rotate in the circumferential direction of the backing block groove and is fixed through a fixing pin. A fixing pin is inserted into different first fixing holes and second fixing holes, the position of the sliding block in the first groove can be adjusted, the normal of the plane of the sliding block is consistent with the axis direction of the end of the horizontal support, the acting force of the jack is consistent with the axis direction of the end of the horizontal support, and multi-angle adjustment of the loading direction of the jack is achieved. The loading direction of the jack meets the construction requirement, and the horizontal support keeps a stable stress system.
本发明公开了一种基坑地下连续墙变形调节支撑结构及其施工方法，围檩槽孔中设置有背衬块、滑块、千斤顶和加载块。所述背衬块上设置有圆弧形的凹槽一和沿径向设置的若干固定孔一；所述滑块包括一个圆弧面和一个平面，所述滑块沿圆弧面的径向间隔设置有若干固定孔二；所述滑块能够沿所述背衬块凹槽的圆周方向转动，并通过固定销固定。将固定销插入不同的固定孔一和固定孔二，能够调节滑块在凹槽一中的位置，使滑块的平面的法线与水平支撑的端部轴线方向一致，从而使千斤顶的作用力与水平支撑端部轴线方向一致，实现千斤顶加载方向的多角度调节，使千斤顶加载方向满足施工需求，使水平支撑保持稳定的受力体系。
