Prefabricated prestressed steel lattice composite foundation pit stand column square pile
A prefabricated prestressed steel lattice composite foundation pit stand column square pile comprises a square pile body, the square pile body is provided with spiral stirrups, angle steel is pre-embedded in the four corners of the upper portion of the square pile body, the length of the pre-embedded angle steel is the sum of the foundation pit excavation depth and the bottom anchoring length, and the angle steel is connected with pipe pile concrete through anchor bars; steel batten plates are arranged on the embedded angle steel from top to bottom according to the interlayer spacing, and a water stop steel plate is arranged at the position, corresponding to a basement bottom plate, of the square pile body. The prefabricated prestressed square pipe pile and the steel lattice are a composite body, the pile driving and forming construction process is unified, environment-friendly treatment objects such as slurry of a cast-in-situ bored pile are not generated, the prefabricated prestressed steel lattice composite square pipe pile is manufactured in a factory mode, and the pile forming quality of the stand column pile is controllable; in order to facilitate static pressure or hammering pile forming, steel batten plates of the prefabricated prestressed steel lattice composite square pipe piles are welded in the earth cutting stage; construction is convenient, and cost is reduced.
一种预制预应力钢格构复合基坑立柱方桩，包括方桩桩体，所述方桩桩体设有螺旋箍筋，所述方桩桩体的上部四个角预埋角钢，所述预埋角钢的长度为基坑开挖深度和底锚固长度之和，所述角钢上通过锚筋与管桩混凝土连接；所述预埋角钢从上到下按照层间距设置钢缀板，所述方桩桩体的地下室底板对应位置上设置止水钢板。本发明预制预应力方管桩和钢格构是一个复合体，打设成桩施工工艺统一，没有产生钻孔灌注桩的泥浆等需要环保处理物，预制预应力钢格构复合方管桩工厂化制作，立柱桩成桩质量可控；为方便静压或者锤击成桩，预制预应力钢格构复合方管桩的钢缀板在挖土阶段焊接；施工方便、降低成本。
