Immersed dry dock for connecting an underground tunnel to an immersed tunnel and the tunnel construction method by using it

摘要

The present invention is easy to connect from one underground (cutlery) underwater tunnel and the tunnel (bridge) to be relates to a continuous tunnel to the underground tunnel and tunnel construction method that can be used underwater for dry dock and connect it to build an underwater tunnel. ; The present invention is mounted in the hands of the coast, is one the top side the rear mouth of the hollow body is formed; Rear doors open toward the underground tunnel at the rear of the main body; The front door opening toward the underwater tunnel in the first half of the main body; And a seal formed at the edge of the front door; including, and is connected to the rear end of the tunnel for the internal unit and the ground connection in the air tunnel ( ) of the main body, the front end of the underwater tunnel unit for the connection at the front of the main body provides an underwater tunnel ( ) underground and underwater tunnels configured to connect in dry dock for connecting the underwater tunnel. ; tunnel that connected by underground tunnels and can be easily connected to an underwater tunnel, according to the present invention the process can be finished in a short period of time, can greatly reduce the construction costs. After the tunnel, as well as the construction is completed, are obtained utilizing the possible effect of the water dry dock for a variety of purposes to be able to take advantage of the artificial island.
