Single-pile foundation supported by inclined piles and construction method of single-pile foundation
The invention discloses a single-pile foundation supported by inclined piles and a construction method of the single-pile foundation. The single-pile foundation comprises large-diameter single piles, the inclined piles, a bearing platform and a supporting device of the bearing platform. The large-diameter single pile and the six inclined piles are circular pipe piles, and the six inclined piles are evenly arranged along the bearing platform at 60-degree intervals. The bearing platform is of a cast-in-place reinforced concrete structure and used for connecting and fixing the large-diameter single pile and the six inclined piles. The supporting device is used for further strengthening connection between the large-diameter single pile and the inclined pile and mainly comprises a large-diameter single pile sleeve, an inclined pile sleeve, a single pile hinge, an inclined pile hinge and a rigid connecting rod. After the large-diameter single pile and the inclined pile are sunk, the large-diameter single pile and the inclined pile are sleeved with the pile body sleeve along the pile body, the pile body of the large-diameter single pile and the pile body of the inclined pile are each provided with an annular supporting table to play a role of a limiting supporting device, and then a high-strength grouting material is injected into a gap between the inner wall of the sleeve and the pile so that the large-diameter single pile and the inclined pile can be firmly bonded; and the single pile hinges and the inclined pile hinges are hinged and connected in a one-to-one correspondence manner through the rigid connecting rods. And finally, bearing platform steel bars are arranged, and bearing platform concrete is poured in two layers.
本发明公开了一种使用斜桩支撑的单桩基础及其施工方法，包括大直径单桩、斜桩、承台及其支撑装置。大直径单桩和6根斜桩为圆形管桩，6根斜桩沿着承台呈60°间隔均匀布置。承台为现浇钢筋混凝土结构，用于连接和固定大直径单桩和6根斜桩。支撑装置用于进一步加强大直径单桩和斜桩之间的连接，主要包括大直径单桩套管、斜桩套管、单桩铰、斜桩铰及刚性连接杆。大直径单桩和斜桩沉桩完成后，沿着桩身套入桩身套管，大直径单桩和斜桩桩身均设有环状支撑台，起到限位支撑装置的作用，然后向套管内壁和桩之间的空隙注入高强灌浆料，使其粘接牢靠，并通过刚性连接杆将单桩铰和斜桩铰一一对应铰接相连。最后布设承台钢筋，分两层浇筑承台混凝土。
