A Submerged Floating Bridge Sheltered in External Tube and a Construction Method of the Submerged Floating Bridge

摘要

The present invention relates to a submersible floating bridge and a construction method thereof, comprising: an outer tube for protecting the main body of the bridge from collision with an underwater floating object or underwater terror, and a submerged diving tube configured to be filled with water between the outer tube and the main body of the bridge. The purpose is to provide a floating floating bridge and its construction method. ; Submersible floating bridge protected by the outer tube of the present invention for achieving the above object is the outer tube in the longitudinal direction, both ends in the land and the middle is located in the water and hollow in the longitudinal direction, the inside of the outer tube Located in the land and both ends on the land and the bridge body that can pass through the hollow formed in the longitudinal direction, and the support member for supporting the middle of the length of the jacket tube does not float above the water surface, the outer tube and the bridge body Between the water is filled with technical features, ; In addition, according to the construction method of the submersible floating bridge of the present invention, the step of fixing both ends of the host cable to the sea bottom, both ends of the hollow tube formed on the land and the middle is located in the water, the outer tube is Constructing to be located inside the host cable, and entering a bridge body in which the hollow is formed into the shell tube in a continuous extrusion method so that both ends of the bridge body are positioned on land; It is characterized in that it comprises a step of tensioning the host cable while the jacket tube is suspended by the buoyancy of the bridge body. ; Submersible Floating Bridge, Jacketed Tube, Bridge Body, Continuous Extrusion, Host Cable, Auxiliary Cable
