Combined foundation pit supporting structure and construction method thereof
The invention discloses a combined foundation pit supporting structure and a construction method thereof, and belongs to the technical field of civil engineering. The foundation pit supporting structure comprises cement soil mixing piles arranged at the outer side of a foundation pit excavation face, rib bodies, reinforcing mesh and a concrete layer. The rib bodies are arranged between the foundation pit excavation face and the cement soil mixing piles, one ends of the rib bodies are anchored in the cement soil mixing piles, and the other ends of the rib bodies are anchored on the foundation pit excavation face; the reinforcing mesh is arranged on the foundation pit excavation face, and the ends, located on the foundation pit excavation face, of the rib bodies are connected with the reinforcing mesh through reinforcing ribs; and the concrete layer is positioned on the surface of the reinforcing mesh. The invention further discloses a construction method of the combined foundation pit supporting structure, the foundation pit supporting structure is water-isolated and waterproof, meanwhile, the strength characteristic of the cement mixing pile waterproof curtain can be brought into full play, and the anchoring effect on the foundation pit supporting structure is more reliable. More importantly, due to the good anchoring effect of the cement soil mixing piles, the length of a ribbody material can be greatly reduced, and the rib body material is limited from the excavation face of the foundation pit excavation face to the interior of the cement soil mixing piles.
本发明公开了一种组合式基坑支护结构及其施工方法，属于土木工程技术技术领域。该基坑支护结构包括水泥土搅拌桩，设置在基坑开挖面外侧；筋体，设置在基坑开挖面与水泥土搅拌桩之间，筋体的一端锚固在水泥土搅拌桩内，另一端锚固在基坑开挖面上；钢筋网片，设于基坑开挖面上，筋体位于基坑开挖面的端部通过加强筋与钢筋网片连接；混凝土层，位于钢筋网片表面。本发明还公开了上述组合式基坑支护结构的施工方法，本发明的基坑支护结构在隔水、防水的同时，能充分发挥水泥土搅拌桩止水帷幕的强度特性，其锚固作用更为可靠。更为重要的是，由于水泥土搅拌桩良好的锚固作用，可以大大降低筋体材料长度，将其限制在基坑开挖面至水泥土搅拌桩内。
