The barges are moored at 4 points in the sea, and two winches are arranged on each barge to realize the submarine pipeline corridor being filled with water in the sea and sunk to the base bed; S205, connection construction between the submarine pipeline corridor and the barrel-type foundation structure: a winch is arranged on the top of the special connection structure of the barrel-type foundation structure, and four cable transfer piles are arranged at the four corners of the joint section; two submarine pipeline corridors are installed symmetrically and simultaneously, and are sunk to the predetermined position by barge; the four winch cables of each special connection structure are connected to the mooring points corresponding to the four corners on the side of the second-type connection head end of the submarine pipeline corridor, the submarine pipeline corridor is pulled toward the docking end on the bed surface, and the water stop is pressed onto the end face of the special connection structure of the barrel-type foundation structure to achieve preliminary water stopping ; Pump water out of the barrel foundation structure and use the barge to continuously twist and shift to achieve preload; sequentially remove the end face of the barrel foundation structure on one side and the end face of the submarine corridor on one side of the special connection structure in the barrel foundation structure; install the OMEGA waterstop through embedded parts; connect the two anchor plates of the two submarine corridors through prestressed steel cables, and tension the prestress to compress the GINA waterstop to the preset amount; install the shear key of the special connection structure between the submarine corridor and the barrel foundation structure to ensure the overall shear resistance of the submarine corridor and the barrel foundation structure; S206, the connection construction between submarine pipeline corridors is carried out by using a special floating barge, arranging winches, arranging 4 cable transfer piles at the 4 corners of the joint section of the first-class connector of the submarine pipeline corridor, and arranging 8 sets in total; the two submarine pipeline corridors are installed symmetrically at the same time and sunk to the predetermined position by using a barge; the 4 winch cables of the first-class connector of each submarine pipeline corridor are connected to the mooring points corresponding to the 4 corners on the side of the end of the first-class connector of the main submarine pipeline corridor on the symmetry axis, and the two symmetrical submarine pipeline corridors are pulled towards the butt end on the surface of the bed, and the water stop is pressed to Initial water stopping is achieved on the end face of the special connection structure of the main submarine corridor; water is pumped out from the inside of the main submarine corridor at the butt end, and the special floating barge is used to continuously twist and shift the structure to achieve preload; the two-layer end faces of the special connection structure in the connected main submarine corridor are sequentially removed; the OMEGA waterstop is installed through embedded parts; the two anchor plates of the two submarine corridors are connected through prestressed steel cables, and the prestress is tensioned to compress the GINA waterstop to a preset amount; the shear keys of the special connection structure of the submarine corridor are installed to ensure the overall shear resistance of the submarine corridor cluster; S207. Install the external protective structure of the connection, and use a combination of steel shell and geotextile materials to provide external protection for the connection.
