Joint combination structure of floating tunnel
The invention relates to a floating tunnel joint combination structure, and belongs to the technical field of floating tunnel joints. Comprising at least two linearly connected pipe joint modules. The adjacent pipe joint modules are connected through rigid joints; each pipe joint module comprises a first pipe joint and a second pipe joint which are connected through a flexible connector. Tenon-shaped shear keys are arranged at one ends of the first pipe joint and the second pipe joint, mortise structures are arranged at the other ends of the first pipe joint and the second pipe joint, and two GINA water stop belts are further arranged on the two sides of the shear keys. The flexible joint comprises prestressed concrete penetrating through the adjacent pipe joints, an anchor seat and an anchorage device; and the rigid joint comprises an anchoring steel bar and concrete which are arranged between the adjacent pipe joint modules. Flexible joint butt joint is completed on the land, rigid joint butt joint is completed underwater, construction is convenient, the sealing waterstop performance between pipe joints is guaranteed, and vibration and deformation generated by floating tunnel joints in the complex marine environment can be resisted.
本发明涉及一种悬浮隧道接头组合结构，属于悬浮隧道接头技术领域。包括至少两个线性连接的管节模块；相邻的所述管节模块之间通过刚性接头相连；每个所述管节模块包括通过柔性接头连接的第一管节和第二管节。第一管节和第二管节的一端设置有榫头状剪力键，另一端设置有卯眼结构，剪力键两侧还设置有两条“GINA”止水带。柔性接头包括贯穿相邻管节的预应力混凝土和锚座、锚具；刚性接头包括设置在相邻管节模块之间的锚固钢筋和混凝土。本发明在陆地完成柔性接头对接，在水下完成刚性接头对接，方便施工，保证了管节间的密封止水性，还能抵御复杂海洋环境下悬浮隧道接头所产生的振动和变形。
