Steel lattice type inclined pile support construction method
The invention discloses a micro-disturbance steel lattice type raking pile support construction method, which comprises the following steps of: firstly, forming a three-section type raking pile by a crown beam connecting section, a loading device and a jet grouting pile connecting section according to a design processing position, then drilling to form a hole, arranging the raking pile below, constructing a raking pile body, and forming a pile end expansion head at the lower end of the raking pile body; and then the top beam and the reinforcing piers are constructed, the top beam, the reinforcing piers and the inclined supporting piles are constructed into an integral structure, certain prestress is applied to the inclined supporting piles through the additionally-installed device after the integral structure is constructed, and finally earth excavation and cushion layer pouring are conducted. According to the method, micro-disturbance deformation of the foundation pit can be better controlled, construction can be carried out before excavation of the foundation pit, safety and reliability of the foundation pit are guaranteed, meanwhile, the construction period can be shortened, cost can be saved, meanwhile, project site construction is facilitated, and the method has high economical, practical and popularization value in foundation pit engineering with the good soil texture condition.
本发明公开了一种微扰动钢格构式斜桩支撑施工方法，该方法为先根据设计加工处以冠梁连接段、加载装置和旋喷桩连接段构成的三段式斜撑桩，然后进行钻进成孔、下方斜撑桩、施工斜桩桩体，并在其下端形成桩端扩大头，再施工冠梁及加强墩，将冠梁、加强墩和斜撑桩构造成一整体结构，完成后通过加装装置对斜撑桩施加一定的预应力，最后进行土方开挖及浇筑垫层。本发明可以更好的控制基坑微扰动变形，能够在基坑开挖前进行施工，在保证基坑安全可靠的同时，不仅可以缩短工期，节约成本，同时方便了项目现场施工，在土质条件较好的基坑工程中具有较高的经济实用和推广价值。
