Large-settlement pile foundation and reinforcing method
The invention discloses a pile foundation with large settlement and a reinforcing method. The pile foundation mainly comprises a bearing platform, a bearing layer, a first cast-in-place pile, a second cast-in-place pile and an inclined pile. The bearing layer is positioned below the bearing platform; the upper ends of the first cast-in-place piles are fixedly connected with the bottom of the bearing platform, and the lower ends extend to a bearing stratum; the upper end of the second cast-in-place pile is fixedly connected with the bottom of the bearing platform, and the lower end extends to the bearing stratum; the inclined upper ends of the inclined piles are fixedly connected with the second cast-in-place piles and the bearing platform, and the lower ends extend to a bearing stratum. According to the reinforcing method of the scheme, the cast-in-situ bored piles and the inclined piles are combined to form the combined pile foundation, in the construction process, the construction reliability is improved, the construction cost is reduced, and the good coordination effect is achieved; finally, the combined pile foundation with the vertical bearing capacity, the horizontal bearing capacity and the anti-shearing function is achieved. Compared with an existing cast-in-situ bored pile group pile foundation, the cast-in-situ bored pile group pile foundation has the advantages that the cost can be reduced, and the pile foundation with excellent vertical bearing capacity and horizontal bearing capacity can be provided.
本发明公开了一种沉降较大桩基础及加固方法，桩基础主要包括承台、持力层、第一灌注桩、第二灌注桩和斜桩；持力层位于承台下方；第一灌注桩的上端与承台底部固定连接，下端延伸至持力层；第二灌注桩的上端与承台底部固定连接，下端延伸至持力层；斜桩倾斜的上端与第二灌注桩和承台固定连接，下端延伸至持力层。本方案的加固方法通过钻孔灌注桩和斜桩组合构成组合桩基础，在施工过程中，提高了施工可靠度，降低施工成本，达到了很好的协调作用；最终实现提供竖向承载力、水平承载力、抗剪功能的组合桩基础。相较于现有的钻孔灌注桩群桩基础，本申请既可以降低成本，又能够提供竖向承载力和水平承载力俱佳的桩基础。
