Problems solved by technology

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 the cycle was long. Long time artificial underwater work

Abstract

The invention discloses a structure form of a final joint of an immersed tunnel and relates to the technical field of communication and transportation. A foundation pad is provided with adjacent long pipe sections on the two sides. The adjacent long pipe sections on the two sides are both provided with jack pushing systems. The end face on one side of one of the adjacent long pipe sections on the two sides is in a wedge shape, the end face on the other side of the other one of the adjacent long pipe sections on the two sides is a vertical end face, and the end faces on the two sides are both provided with steel end shells. A single-sided wedge-shaped block is inserted between the end faces on the two sides of the adjacent long pipe sections on the two sides. The end faces on the two sides of the adjacent long pipe sections on the two sides are provided with the first steel end shells. GINA water stops are mounted on the peripheries of the first steel end shells. The adjacent long pipe sections on the two sides are both internally provided with end sealing walls. The two sides of the single-sided wedge-shaped block are provided with second steel end shells. The immersed final joint is small in structure size and convenient to prefabricate, and the construction quality can be ensured easily; through the double-sided wedge shape, the construction difficulty is low, compression of the water stops is facilitated, and the final joint block is not liable to be squeezed out by water pressure; and the construction speed of underwater mating of prefabricated parts is high.

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...
