Soft soil foundation pit supporting structure, supporting method thereof and lattice type steel pipe pile
The invention belongs to the field of soft soil foundation pit supporting, and discloses a soft soil foundation pit supporting structure, a supporting method of the soft soil foundation pit supporting structure and lattice type steel pipe piles, and the soft soil foundation pit supporting structure is characterized in that the multiple lattice type steel pipe piles are arranged on the soil retaining side; the lattice type steel pipe pile is composed of a three-limb lacing bar type pile body and a coping plate welded to the top of the pile body, and a hole is formed in the middle of the coping plate. The lattice type steel pipe piles are all arranged on the soil retaining side in a forward mode or/and alternately arranged in one row or multiple rows in a forward and reverse mode. The row of lattice type steel pipe piles located on the free side are connected together through a plurality of waist beams. The lattice type steel pipe pile is adopted as a support of the soft soil foundation pit, and compared with a conventional rotary digging hole-forming pouring support pile, the construction period can be greatly shortened, and the construction cost is saved; and compared with steel sheet pile supporting, the lateral stiffness of the supporting structure can be improved, deformation is effectively restrained, and safety is improved.
本发明属于软土基坑支护领域，公开了一种软土基坑支护结构及其支护方法和格构式钢管桩，其中所述软土基坑支护结构，由多根格构式钢管桩排布于挡土侧；所述格构式钢管桩由三肢缀条式桩体和焊接于桩体顶部的压顶板组成，所述压顶板的中部设置有孔洞；所述格构式钢管桩于挡土侧全部正置或/和一正一反交替布置有一排或多排；位于临空侧的一排所述格构式钢管桩通过多根腰梁连接在一起。本发明采用格构式钢管桩作为软土基坑的支护，相对于常规旋挖成孔灌注支护桩，能大大缩短工期，节省施工成本；相对于钢板桩支护，能提高支护结构的抗侧刚度，有效的抑制了形变，增加了安全性。
