Combined inclined pile support foundation pit supporting structure and construction method thereof
The invention relates to a combined inclined pile support foundation pit supporting structure and a construction method thereof.The supporting structure comprises a soil retaining component, an inclined pile steel pipe, an inclined pile connector, a diameter expanding component, a diameter expanding rib plate and a steel pipe reinforcing core, and the inclined pile steel pipe is a component or component combination which is obliquely arranged, has the axial compression resistance bearing function and is provided with a hollow channel; the expanding component is firmly connected with the bottom of the inclined pile steel pipe and has a soil splitting and reaming function, and the expanding rib plates are firmly connected with the inclined pile steel pipe, distributed in the length direction of the inclined pile steel pipe and formed by one or more of cement paste, cement mortar or concrete. The foundation pit supporting structure is high in construction mechanization degree, low in manufacturing cost and high in speed, and the foundation pit supporting structure is high in safety degree, suitable for avoiding engineering piles in a foundation pit and good in construction quality.
本发明涉及一种组合斜桩撑基坑支护结构及其施工方法，该支护结构包括挡土构件、斜桩钢管、斜桩连接、扩径构件、扩径肋板、钢管加强芯六部分，其中的斜桩钢管是倾斜放置的具备轴向抗压承载功能的且带有中空通道的构件或构件组合，扩径构件是与斜桩钢管底部牢固连接的具备劈裂土体扩孔功能的构件，扩径肋板是与斜桩钢管牢固连接且沿着斜桩钢管长度方向分布的由水泥浆、水泥砂浆或混凝土中的一种或几种组合形成的构件，斜桩钢管与挡土构件共同作用形成基坑支护结构，本发明施工机械化程度高、造价低、速度快，本发明的基坑支护结构安全度高，适于避让基坑内部的工程桩，施工质量好。
