End sealing door structure for immersed tube tunnel
The invention relates to the field of immersed tube tunnels and provides an end sealing door structure for an immersed tube tunnel. The end sealing door structure is arranged at each of two ends of each tube hole of a prefabricated tube segment and comprises a plurality of first embedded parts and a sealing door face plate. The first embedded parts are embedded at the end of the tube hole along the circumferential direction of the inner wall, steel plates of the first embedded parts are in close end-to-end connection, and the steel plate surfaces of the first embedded parts expose from the inner wall of the tube hole. The sealing door face plate is formed by assembling a plurality of independent abreast strip steel plates, the edges of the strip steel plates are in sealed and welded connection with the steel plates of the first embedded parts through first sealing steel plates, and the strip steel plates are in welded connection through second sealing steel plates, so that the assembled welded water-stop end sealing door structure is formed. Compared with an existing disposable end sealing door structure and an existing assembled rubber water-stop end sealing door structure, the end sealing door structure for the immersed tube tunnel has the advantages of convenience in assembly and disassembly, lower labor consumption, reusability, lower engineering material consumption, high adaptability to sealing door face plate deformation and assembly error and lower engineering waterproofing safety risks.
