Sheet pile supporting structure of foundation pit in deep foundation pit and construction method of sheet pile supporting structure
The invention discloses a sheet pile supporting structure of a foundation pit in a deep foundation pit and a construction method of the sheet pile supporting structure, the supporting structure comprises four rows of piles which are connected end to end, and each row of piles comprises a plurality of prefabricated unit sheet piles arranged in the circumferential direction of the foundation pit in the deep foundation pit and connecting structures connected to the prefabricated unit sheet piles of adjacent beams. Stiffening ribs are formed on the inner sides of the prefabricated unit sheet piles, the thickness of the lower ends of the prefabricated unit sheet piles is gradually reduced from top to bottom, and every two adjacent row piles are connected together through corner structures to form a rectangular sheet pile supporting structure. The problem that the construction efficiency of a deep foundation pit foundation with a pit-in-pit is low is solved.
本发明公开了一种深基坑内的基坑的板桩支护结构及其施工方法，该支护结构包括首尾相接的四排桩，所述排桩包括沿深基坑内的基坑的周向方向设置的多个预制单元板桩和连接于相邻梁所述预制单元板桩的连接结构，所述预制单元板桩的内侧形成有加劲肋，所述预制单元板桩的下端的厚度自上而下逐渐变小，相邻的排桩分别通过转角结构两两连接在一起形成矩形板桩支护结构。本发明解决了具有坑中坑的深基坑基础施工效率低的问题。
