Square and round pile combined foundation pit supporting method
The invention relates to the technical field of foundation pit supporting in construction engineering, and discloses a square and round pile combined foundation pit supporting method. The square and round pile combined foundation pit supporting method comprises the following steps of S1, designing parameters; S2, conducting round pile construction; S3, conducting square pile construction; S4, conducting waterproof curtain construction; S5, conducting beam construction; S6, conducting anchor rod construction; and S7, conducting anchor rod locking. According to the square and round pile combinedfoundation pit supporting method, all round piles are connected through round pile top beams, then the round pile top beams and all square piles are connected through straining beams to form a stablewhole, and finally prestress is applied to outriggers connected with the square piles through anchor rods, so that the stability of the whole square and round pile combined supporting structure is improved. According to the square and round pile combined foundation pit supporting method, the advantage of convenience in round pile construction is exerted, the supporting advantage that the square piles can provide high bending resistance is exerted, meanwhile, the phenomenon that the anchoring length of the anchor rods is insufficient or space of an adjacent building (structure) is occupied dueto the fact that the anchor rods are constructed towards the outer side of a foundation pit can be avoided, the supporting effect is improved, and the cost is reduced.
本发明涉及建设工程中基坑支护的技术领域，公开了方圆桩组合基坑支护方法，包括下述步骤：S1、参数设计；S2、圆桩施工；S3、方桩施工；S4、止水帷幕施工；S5、梁施工；S6、锚杆施工；S7、锚杆锁定；本发明通过圆桩冠梁将所有圆桩进行连接，再通过拉梁将圆桩冠梁与所有方桩进行连接形成一个稳定的整体，最后再用锚杆将预应力施加于与方桩连接的挑梁上，增加了整个方圆桩组合支护结构的稳定性；本发明既发挥了圆桩施工便捷的优势，也发挥了方桩能提供较大抗弯性能的支护优势，同时也能避免因锚杆向基坑外侧施工导致的锚杆锚固长度不足或侵占邻近建(构)筑物空间的现象，提高了支护效果，且降低了成本。
