However, this type of steel end shell also has the following disadvantages: the welded I-shaped steel of the steel end shell is a large-scale steel structure in which the I-shaped steel goes around a circle along a rectangular track line. Due to the large size of the track line, the welded I-shaped steel The size of the section steel is relatively small. If the steel end shell is processed into an integral member without segmentation, it will cause the steel end shell to be easily deformed and difficult to transport.

The invention relates to a segmented assembly component of steel end housings of an underwater tunnel immersed segment and a construction method. The segmented assembly component of the end housings comprises a plurality of steel end housings, which is characterized in that each steel end housing comprises a body (1) and a panel, wherein the body (1) is of frame structure which is formed by I-shaped steels; the panel is matched with the body (1) and the size and the shape of the panel coincide with those of the body (1) (the panel can be of frame structure formed by the steel plates); the body (1) is divided into a top body (11) and a bottom body (12); the top body (11) is of inverse U-shaped structure and is formed by two or more sections of I-shaped steels; the bottom body (12) is of U-shaped structure and is formed by two sections or more sections of I-shaped steels; and the panel is formed by two or more sections of steel plates. The invention has the characteristics of reasonablesegmentation, convenient transportation of components and effective prevention of component deformation and can meet requirement of the large-scale steel structure for high integral accuracy.
Description
technical field [0001] The invention relates to a segmented assembly component and a construction method of a steel end shell of an immersed tube section of an underwater tunnel, which is suitable for on-site welding and assembly construction methods of large steel structures. The utility model belongs to the technical field of underwater tunnel components and construction. Background technique [0002] Immersed tube for underwater tunnel is the abbreviation of prefabricated pipe section sinking method, and it is a construction method for building tunnels under water. The construction sequence is to first make the tunnel pipe section (using steel plate and concrete or reinforced concrete) on the berth or in the dry dock, seal the two ends of the pipe section with a temporary sealing wall, and then slide into the water (or release water in the dock) to make it float in the water , and then dragged to the tunnel design location. After positioning, load the pipe section to ma...
