Construction method of deep foundation pit supporting structure in narrow and small area
The invention belongs to the technical field of foundation pit supporting, and discloses a construction method of a deep foundation pit supporting structure in a narrow and small area, which comprises the following steps: S1, constructing two rows of supporting piles distributed inside and outside at the periphery of a foundation pit; s2, outer-layer top beam construction is conducted on the supporting piles located on the outer side; and S3, inner-layer top beam construction is conducted on the supporting piles located on the inner side, multiple haunched wall construction is conducted between the outer-layer top beam and the inner-layer top beam while the inner-layer top beam construction is conducted, one end of each haunched wall is connected with the outer-layer top beam, and the other end of each haunched wall is connected with the inner-layer top beam. According to the construction method of the deep foundation pit supporting structure in the narrow and small area, the multiple haunching walls are arranged between the outer-layer top beam and the inner-layer top beam, the stress performance and the deformation characteristic of the supporting piles can be optimized, the site utilization rate of the narrow and small space is further increased, and the influence on surrounding buildings and the environment is reduced.
本发明属于基坑支护技术领域，公开了一种狭小地区深基坑支护结构的施工方法，包括如下步骤：S1：在基坑的周边进行两排内外分布的支护桩施工；S2：在位于外侧的所述支护桩上进行外层冠梁施工；S3：在位于内侧的所述支护桩上进行内层冠梁施工，在所述内层冠梁施工的同时在所述外层冠梁和所述内层冠梁之间进行多个加腋墙施工，将所述加腋墙的一端与所述外层冠梁连接，所述加腋墙的另一端与所述内层冠梁连接。该狭小地区深基坑支护结构的施工方法通过在外层冠梁和内层冠梁之间设置多个加腋墙，能够优化支护桩的受力性能和变形特性，进一步提高狭小空间的场地利用率，减少对周边建筑物及环境的影响。
