Diagonal support threaded pile supporting structure for foundation pit enclosure and construction method thereof
The invention discloses a diagonal support threaded pile supporting structure for foundation pit enclosure. The structure comprises supporting piles, a foundation bottom plate under a soil layer and aplurality of threaded piles. The upper ends of all the threaded piles are connected with the upper ends of the supporting piles, each threaded pile penetrates through the foundation bottom plate, atleast part of each threaded pile enters a force supporting soil layer under the foundation bottom plate, and the threaded piles are gradually and oppositely inclined from top to bottom. The structureis characterized in that water stop sleeves are arranged in the foundation bottom plate and at the positions where the threaded piles penetrate; and the water stop sleeves are arranged on the peripheries of the threaded piles and are detachably connected with the threaded piles. The invention also disclosed is a construction method of the diagonal support threaded pile supporting structure. Compared with the prior art, the method has the advantages that the water stop sleeves are arranged in the foundation bottom plate and are detachably connected with the threaded piles, so that the threadedpiles can be conveniently dismounted and recycled, the construction cost is reduced, the problem of construction joints does not need to be considered, and later structure processing is simple and convenient, and the quality is reliable.
本发明公开了一种用于基坑围护的斜向支撑螺纹桩支护结构，包括支护桩、位于土层下方的基础底板和多个螺纹桩，每个螺纹桩的上端与支护桩的上端连接，每个螺纹桩穿过基础底板而至少部分进入基础底板下方的撑力土层，所述螺纹桩由上至下逐渐相向倾斜，其特征在于：所述基础底板内、在被螺纹桩贯穿处设置有止水套管，所述止水套管设置在螺纹桩外周、并且与螺纹桩可拆卸连接。还公开了该斜向支撑螺纹桩支护结构的施工方法。与现有技术相比，本发明的优点在于：通过在基础底板内设置止水套管、止水套管与螺纹桩可拆卸连接，可便于螺纹桩拆除回收，降低了施工成本，无需考虑施工缝的问题，后期结构处理简便、质量可靠。
