Inclined rod type foundation pit supporting system and construction method
The invention relates to the field of building foundation pit construction, in particular to an inclined rod type foundation pit supporting system. The inclined rod type foundation pit supporting system involves a deep foundation pit body, wherein water stop piles and supporting piles are arranged inside the deep foundation pit body, supporting structures are arranged on one sides of the supporting piles, and each supporting structure comprises an inclined supporting part and a horizontal supporting part. The invention further provides a construction method of the inclined support foundation pit supporting system. The construction method comprises the following steps that 1, a deep foundation pit is excavated on the ground to a first-time excavation face; 2, the supporting piles, the waterstop piles, supporting stand columns and inclined supporting rods are driven on the first-time excavation face; 3, top beams and connecting beams are arranged at the upper ends of the supporting piles; and 4, the deep foundation pit is excavated to the bottom surface of the foundation pit. According to the inclined rod type foundation pit supporting system, the horizontal supporting parts can conduct the pressure of a soil layer on the outer side of the foundation pit to the inclined supporting parts, the inclined supporting rods generate upward moment and can act on the supporting piles together with the horizontal supporting parts, and therefore the influence of the soil pressure on the supporting piles can be counteracted, the deformation phenomenon of the supporting piles is effectively avoided, and good construction quality can be guaranteed.
本申请涉及建筑基坑施工的领域，具体为一种斜杆式基坑支护体系，其包括深基坑本体，深基坑本体内设置有止水桩和支护桩，支护桩的一侧设置有支护结构，支护结构包括斜支撑部和水平支撑部。还提供一种斜支撑基坑支护体系的施工方法，包括以下步骤：Step1：在地面开挖深基坑至第一次开挖面；Step2：在第一次开挖面上打设支护桩、止水桩、支护立柱和斜支撑杆；Step3：在支护桩上端设立冠梁和连系梁；Step4：将深基坑开挖至基坑底面。本申请中的水平支撑部能够将基坑外侧土层的压力传导至斜支撑部上，斜支撑杆产生向上的力矩，可以与水平支撑部共同作用于支护桩，因此能够抵消土压力对支护桩产生的影响，有效解决支护桩的形变现象，可以保证较好的施工质量。
