Novel supporting pattern combining inclined piles with vertical anchors
The invention mainly relates to the field of foundation pit engineering, in particular to a novel supporting pattern combining inclined piles with vertical anchors. The novel supporting pattern mainly comprises inclined piles, vertical anchors, top beams and cement soil mixing piles, wherein the inclined piles are mainly used for retaining soil in the front row and supporting slope soil, and the tops of the inclined piles are connected into a whole through the top beams; the vertical anchors are used for improving anti-overturning capacity of the inclined piles and controlling the horizontal displacement of the side wall of a foundation pit, and overall stability of the whole structure is improved; the cement soil mixing piles are mainly used for stopping water, and it is guaranteed that soil on the lower portion of the inclined piles is dry and anchoring force of an anchor rod or an anchor cable is not lost through precipitation. The novel supporting pattern is a foundation pit enclosure structure without an inner support, the influence of excessive deformation of the side wall of the foundation pit on the surrounding environment can be reduced, the influence of a traditional inner support structure on earth excavation and underground structure construction is avoided, and the construction period of a project is shortened.
本发明主要涉及基坑工程领域，是一种斜桩结合竖锚的新型支护型式，新型支护型式的主要构成有：斜桩、竖锚，冠梁、水泥土搅拌桩。斜桩的主要作用是前排挡土及支撑坡面土体，顶部通过冠梁相连成为一体；竖锚的作用是增加斜桩的抗倾覆能力和控制基坑侧壁的水平向位移、增加整个结构的整体稳定性；水泥土搅拌桩的主要作用是止水，通过降水，保证斜桩下部土体干燥及锚杆或锚索锚固力不损失。本新型支护型式是一种无内支撑的基坑围护结构，可减小基坑侧壁变形过大对周边环境产生的影响，避免了传统内支撑结构对土方开挖及地下结构施工的影响，缩短工程的施工工期。
