Construction method for improving bearing capacity of natural foundation by embedding foundation raft into slope protection pile
The invention discloses a construction method for improving the bearing capacity of a natural foundation by embedding a foundation raft into a slope protection pile, which comprises the following steps of: adding a lateral force resisting system, monitoring a foundation pit, determining a chiseling sequence, chiseling the slope protection pile, treating the section of the slope protection pile, constructing a waterproof layer and constructing an overhanging section raft. Under the condition that the excavation size of an original foundation pit and the positions of the slope protection piles are not changed, the raft plates are implanted into the slope protection piles in a segmented mode, the slope protection piles are equivalent to foundation piles, one pile has multiple purposes, the slope protection piles serve as a part of foundation treatment, the bearing capacity of a foundation is increased, after the raft plates are constructed in a segmented mode, the slope protection piles are supported by the raft plates at the chiseling positions of the implanted slope protection piles, construction is convenient and fast, and the construction efficiency is improved. The earth excavation volume is reduced, and the construction cost is saved.
本发明公开了基础筏板嵌入护坡桩提高天然地基承载力施工方法，包括以下步骤，增设抗侧力体系→基坑监测→确定剔凿顺序→护坡桩剔凿→护坡桩断面处理→防水层施工→外伸段筏板施工，在原有基坑开挖尺寸及护坡桩位置不变的情况下，将筏板分段植入护坡桩内，使护坡桩等效为地基桩，一桩多用，护坡桩作为地基处理的一部分，增加地基的承载力，筏板分段施工后，植入护坡桩剔凿位置由筏板对护坡桩进行了支顶，施工便捷，减少了土方开挖量，节约施工成本。
