Description

Connecting device for connecting an underwater tunnel and an underground tunnel and a method for connecting an underwater tunnel and an underground tunnel using the same

The present invention relates to a connection device for connecting an underwater tunnel and an underground tunnel and a method for connecting an underwater tunnel and an underground tunnel using the same. More specifically, it relates to an underwater tunnel that operates while floating in the water and an underground tunnel. It relates to a connection device and a method of connecting an underwater tunnel and an underground tunnel using the same.

Undersea tunnels or immersed tunnels are used to connect land that is disconnected by the sea, rivers, etc. Since tunnels of this type are located at the bottom or surface of the seafloor, there is a problem that construction is impossible or requires a high construction cost when the depth of the seafloor is deep.

The underwater tunnel, which is being actively researched to solve these problems, is a tunnel that operates while floating in the water, and is a technology in the invention stage whose construction has not yet been completed. Therefore, there is no need for construction methods or related devices for connecting the underwater tunnel to the ground. There is a lack of technology and information.

Because the underwater tunnel is located underwater, it needs to be connected to a tunnel located on the ground in order to connect it to the ground. However, excavation from the ground into the water or from the water into the ground is not easy, and a method that precedes the construction of the dam is generally considered.

In other words, connecting an underwater tunnel and a tunnel located in the ground (hereinafter referred to as an underground tunnel) requires a long construction period and a lot of construction costs, and underwater tunnels and underground tunnels are only built on shallow coastal areas where dam barriers can be constructed. There is a problem with being able to connect.

On the other hand, since underwater tunnels are supported using mooring lines or pontoons, they are not stationary and move with a certain amount of displacement, but in the case of underground tunnels, relatively little displacement occurs because they are restrained by the ground. Therefore, if displacement due to the dynamic behavior of the underwater tunnel is not allowed at the part that connects the underwater tunnel and the underground tunnel (hereinafter referred to as the connection part), there is a risk that stress will be concentrated in the connection part and the connection part will be destroyed.

Likewise, when structures located underwater are destroyed, human and material damage is severe and repairs are difficult.

Therefore, when constructing a connection between an underwater tunnel and an underground tunnel, it is possible to prevent the infiltration of water such as seawater or river water without constructing a fence, and to prevent stress concentration due to the dynamic behavior of the underwater tunnel at the connection area. There is a need to develop a connection device that connects an underwater tunnel and an underground tunnel and a connection method using the same.
