The present invention relates to a connection structure of a submerged floating tunnel unit and, more specifically, to a connection structure of first and second submerged floating tunnel units which are consecutively connected to each other to form a submerged floating tunnel and have first and second longitudinal through parts in the centers thereof. The connection structure of a submerged floating tunnel is described as follows. A protrusion part is formed in one end of the first submerged floating tunnel unit, and a mounting part where the protruding part is mounted is formed in the other end of the second submerged floating tunnel unit. Gaskets are installed to adhere to the protrusion part and the mounting part. A first protruding part of a first concrete structure is formed to protrude outward from one end of the first submerged floating tunnel unit, and a second protruding part is formed to protrude outward from the other end of the second submerged floating tunnel unit. The first and second protruding parts are installed in a row to allow both ends of a supporting wire to be fixed thereto. A turnbuckle for controlling tension is installed in the supporting wire. According to the present invention, one end of the submerged floating tunnel units is formed to be convex, and the other end of the submerged floating tunnel units is formed to be concave in order to securely connect the submerged floating tunnel units to each other, thereby preventing torsion caused by tidal currents. Moreover, the present invention facilitates the connection work of the submerged floating tunnel units by forming the concrete structures in the submerged floating tunnel units, supporting the concrete structures using the supporting wire, and easily controlling the tension of the supporting wire through the turnbuckle. |
