Abstract

The invention relates to the technical field of immersed tunnels, in particular to a movable water stop system of a final connector and an application method. The final connector and a pushing small beam are provided with an outer water stop device making an annular cavity and outer water flow relatively sealed. The outer water stop device comprises a flexible water stop belt, one end of the flexible water stop belt is connected with the final connector, the other end of the flexible water stop belt is connected with the pushing small beam, and the stretching length of the flexible water stopbelt corresponds to the outward movement length of the pushing small beam. An inner water stop device is further arranged in a cavity body of the annular cavity. The movable water stop system is formed by the outer water stop device and the inner water stop device of the water stop system at the same time. The dual water stop devices are adopted, the function of composite water stop is achieved, and when the outer water stop device leaks or is damaged, the inner water stop device plays a role, the purpose of water stop is further achieved, and smooth installation of the final connector is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of immersed tube tunnels, in particular to a mobile water-stop system for a final joint and a method for using it. Background technique

[0002] Immersed tube tunnel construction is to float and transport the prefabricated tunnel caissons in semi-submerged barge or dry dock to the predetermined position for sinking and docking. In order to make the last pipe section sink smoothly, a distance longer than this pipe section must be left Space, the pipe section placed butted in the remaining distance space is regarded as the final joint. The final joint of the immersed tube tunnel is the key to the construction of the immersed tube tunnel. Because the final joint itself has the characteristics of large volume and complex structure, especially in the construction of the ultra-long immersed tube tunnel in the open sea, the construction of the final joint is very difficult. The fine design of the final joint's own...
