Prestressed pipe pile and profile steel pile combined foundation pit supporting structure and construction method
The invention provides a prestressed pipe pile and profile steel pile combined foundation pit supporting structure and a construction method. The foundation pit supporting structure comprises a plurality of prestressed pipe piles and a plurality of U-shaped steel sheet piles, and the prestressed pipe piles and the U-shaped steel sheet piles are arranged at intervals. Two spiral opening pipes are arranged on the circumferential face of the prestressed pipe pile, and sealing pieces are arranged in the spiral opening pipes. The edge of the U-shaped steel sheet pile is embedded in the spiral open pipe, and the sealing piece is used for sealing a fit clearance between the U-shaped steel sheet pile and the spiral open pipe. According to the foundation pit supporting structure, the U-shaped steel sheet piles are arranged between the adjacent prestressed pipe piles, the edges of the two sides of the U-shaped steel sheet piles are embedded into the spiral open pipes, the sealing pieces in the spiral open pipes can seal fit clearances between the U-shaped steel sheet piles and the prestressed pipe piles, and therefore the water stopping effect is achieved; the arrangement of a waterproof curtain is reduced, the foundation pit supporting structure is simplified, and the cost is saved. Meanwhile, the U-shaped steel sheet piles can prevent muck between the prestressed pipe piles from collapsing and falling off.
本申请提供一种预应力管桩与型钢桩组合基坑支护结构及施工方法。基坑支护结构包括若干预应力管桩和若干U型钢板桩，且预应力管桩和U型钢板桩间隔设置；预应力管桩周面设有两条螺形开口管，且螺形开口管内设置有密封件；U型钢板桩的边缘嵌于螺形开口管内，密封件用于密封U型钢板桩与螺形开口管之间的配合间隙。本申请提供的基坑支护结构通过使U型钢板桩设置于相邻的预应力管桩之间，并使U型钢板桩的两侧边缘嵌于螺形开口管内，螺形开口管内的密封件可以密封U型钢板桩和预应力管桩之间的配合间隙，从而达到止水的效果，减少止水帷幕的设置，简化基坑支护结构，节约成本。同时，U型钢板桩可以防止预应力管桩之间的渣土坍塌掉落。
