CONNECTING STRUCTURE OF UNDERWATER TUNNEL UNIT

摘要

The present invention relates to a connecting structure of a submerged floating tunnel. In the connecting structure of a first and a second submerged floating tunnel unit wherein a first and a second penetrating part in a length direction are formed at the center while constituting the submerged floating tunnel, a protrusion part is formed at one end of the first submerged floating tunnel unit and has an outer diameter getting smaller as going to the end. A first slope in multiple stages is formed in the protrusion part. A second slope of multiple stages is formed at the other end of the second submerged floating tunnel unit in a shape that the first slope of multiple stages is mounted. An inner diameter of the second slope gets smaller as going from the end to the inside thereof. According to the present invention, combining force between the submerged floating tunnel units is increased by combining of the slope by forming the slope of multiple stages to correspond to a connection part of the submerged floating tunnel unit. Also, durability of the submerged floating tunnel can be improved since resistance to shear and distortion is improved.
