Foundation pit supporting and protecting structure
The invention provides a foundation pit supporting and protecting structure. The foundation pit supporting and protecting structure is suitable for being set around the periphery of a foundation pit,and comprises reinforced composite pile bodies, lapping piles, and supporting structures. The reinforced composite pile bodies are suitable for being buried in the soil, and comprise rigid core pilesand semi-rigid pile castings covering the periphery of the pile castings. The lapping piles are rigid or semi-rigid pipes. The lapping piles are adjacent to the reinforced composite pile bodies and arranged in a periodic linear array mode and in a ring shape. The supporting structures are fixedly connected with the reinforced composite pile bodies. At least part of the supporting structures are suitable for being arranged above the soil layer and supporting the structure in the foundation pit. By arranging the reinforced composite piles, the complementary enhancement of the rigid piles and thesemi-rigid piles is formed, which not only guarantees the strength of the pile bodies, but also improves the binding force between the pile bodies and the surrounding soil. By arranging lapping piles, the shear capacity of the surrounding soil layer is improved, the horizontal bearing capacity of the reinforced composite piles is improved, and the ability of the supporting structures to resist the lateral force of the surrounding soil is increased. The supporting structures can be used as auxiliary supports to reduce the requirement to backfill pressure coefficient of the surrounding backfillsoil and reduce the construction difficulty.
本发明提供一种基坑支护结构，适于设置在基坑周侧，包括：劲性复合桩体，适于埋设于土中，包括呈刚性设置的桩芯和包裹在桩芯周侧呈半刚性的外桩；搭接桩，呈半刚性或刚性设置，与劲性复合桩体相邻并呈周期线性排列，并呈环形围设；支撑结构，与劲性复合桩体固定连接，至少部分支撑结构适于设置在土层上方并支撑基坑中的结构。通过设置劲性复合桩体，形成刚性桩和半刚性桩的互补增强，在保证桩身强度的同时，提高了桩体与周边土体的结合力，设置搭接桩，提高周边土层的抗剪能力，提高劲性复合桩的水平承载力，增大了支护结构抵抗周边土体侧力的能力。支撑结构的设置，可以作为辅助支撑，降低对周边回填土的回填压系数的要求，降低了施工难度。
