Prestressed pipe joint connector structure of cross-sea suspension tunnel and construction method
The invention discloses a cross-sea floating tunnel prestressed pipe joint connector structure and a construction method, a cross-sea floating tunnel can be constructed by using the structure, and the cross-sea floating tunnel prestressed pipe joint connector structure comprises a prestressed anchor cable, a prestressed pressure-bearing foundation, a connector foundation, an end steel shell, a pressure-bearing ring and a water stop belt; the pre-stressed anchor cable is inserted above the pipe joint connector through the pre-stressed pressure-bearing foundation, the end steel shells are located at the head and the tail of the pipe joint connector respectively, and the pressure-bearing rings are arranged on the pipe joint connector foundation in a staggered mode. The waterstop is arranged on the end steel shell of the pipe joint connector. The pipe joint connector structure is provided with the annular pressure-bearing rings and the pre-stressed anchor cables, so that the suspension tunnel can keep the stability of the structure under the load of a complex marine environment, and meanwhile, the water tightness and the shock absorption performance of the structure are ensured. Through the pre-stressed anchor cable and the pre-stressed pressure-bearing foundation, the pressure stress is pre-stressed on the structure to completely or partially counteract the tensile stress caused by the load, so that the bending resistance and torsion resistance of the structure can be greatly improved, meanwhile, the structure type is simple, and the safety performance of the structure can be greatly improved.
本发明公开一种跨海悬浮隧道预应力管节接头结构及施工方法，利用该结构可构建跨海悬浮隧道，包括预应力锚索、预应力承压基础、接头基础、端钢壳、承压环、止水带；预应力锚索通过预应力承压基础穿插在管节接头上方，端钢壳分别位于管节接头首尾，承压环交错布置在管节接头基础上；止水带布置在管节接头的端钢壳上。本管节接头结构设置环向的承压环与预应力锚索，能够让悬浮隧道在复杂海洋环境荷载下保持结构的稳定性，同时保证结构的水密性和减震性。通过预应力锚索与预应力承压基础，对结构预加压应力以全部或部分抵消荷载导致的拉应力，不仅能够大大提高结构的抗弯能力与抗扭转能力，同时结构型式简单，能大大提高结构的安全性能。
