Abstract

A structural form of the final joint of an immersed tube tunnel, which relates to the technical field of transportation; the foundation cushion is provided with adjacent long pipe joints on both sides, and a jack pushing system is provided on the adjacent long pipe joints on both sides, and the two sides One end face of the adjacent long pipe section is wedge-shaped, and the other end face is a vertical end face, and the end faces on both sides are equipped with rigid end shells, and a single-sided wedge-shaped block; the two sides of the adjacent long pipe joints on both sides are equipped with a first rigid end shell, the outer circumference of the first rigid end shell is equipped with a GINA waterstop, and the adjacent long pipe joints on both sides are provided with end Sealing wall; the two sides of the single-sided wedge-shaped block are installed with second rigid end shells. The structure size of the final joint of the immersed tube in the present invention is small, the prefabrication is convenient, and the construction quality is easy to ensure; the single-sided wedge shape is less difficult to construct, easy to compress the waterstop, and the final joint block is not easy to be squeezed out by water pressure; the prefabricated components are docked underwater, and the construction speed is fast. quick.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a structural form of the final joint of an immersed tube tunnel. Background technique [0002] my country has a vast territory, a long coastline, and numerous rivers, lakes, and islands. In recent years, underwater tunnels with little impact on the environment and landscape have been adopted. A considerable part of the underwater tunnels are constructed using the immersed tube method. [0003] The final joint of the immersed tube method tunnel is an important connection structure to realize the final penetration of the tunnel, and it is also a key link in the key process of the entire project. In the past, the final joint construction of underwater tunnels often used to install the water-stop steel sealing plate underwater around the joint, and then cast the reinforced concrete structure of the joint inside the sealing plate. The construction process was complicated and th...
