Description

[0001] IMPACT ABSORBING IMMERSED TUNNEL [0002]

The present invention relates to an underwater tunnel, and more particularly to an underwater underwater tunnel that minimizes impact transmission from land.

Underwater tunnels are hollow pipes that are supported by buoyancy in the water, and means long-distance continental connection means that cars or railways can run into hollow pipes.

The above-mentioned underwater tunnels can solve the problems due to long-distance construction and the risk of leakage and collapse of the soft ground, as compared with the submarine tunnels connecting the continents by constructing a tunnel below the sea floor. Furthermore, since the hollow pipe can be modularized and manufactured on the land, assembled and connected at sea, it is possible to complete the railway, thereby reducing the construction cost and construction time of the tunnel.

In addition, fixed structures are installed in the middle of underwater tunnels to provide a space for ventilation or rest, and stability that can be utilized as an evacuation space when an underwater tunnel is submerged or collapsed due to unavoidable problems.

However, the above-mentioned underwater tunnel may transmit a vibration or an impact caused by an earthquake or the like generated at the beginning of an underwater tunnel connected with the land, which may cause a problem of lowering safety and durability.

Prior art related to securing safety through the shock absorption of an underwater tunnel includes Korean Patent Application No. 10-2008-0074924 and Japanese Patent Application No. 10149574. However, it is not applicable to a technique directly related to an underwater tunnel, There is a problem that the effect of shock absorption is not high.

Especially, in case of underwater tunnel, it is very important to ensure safety because it is directly connected to a large accident when it is damaged by impact transmitted from land. However, up to now, there is a separate structure for absorbing shock from land or preventing it And the structure to secure the stability of underwater tunnels is not developed.

The spacing between adjacent posts increases as the distance from the land surface increases, and may be equal to each other at a distance from the land surface.

In one embodiment, each of the adjacent tunnel modules may include an outer surface. The fixing portion may include an outer fixing portion fixed to an outer surface of the outer side surfaces of the adjacent tunnel modules and an inner fixing portion fixed to the inner surfaces of the outer surfaces of the adjacent tunnel modules.

1 and 2, the underwater tunnel 1 according to the present embodiment includes a tunnel portion 100, a support frame portion 200, and a fixing portion 150.

The underwater tunnel 1 is installed under the sea surface 1, that is, in the sea, and the tunnel part 100 is connected to the land in the form of a tunnel through the land surface 2 and extends to the sea.

The tunnel portion 100 may have a hollow portion formed therein, and a train, an automobile, or the like may be driven into the tunnel portion 100. In addition, the tunnel unit 100 includes a plurality of tunnel modules coupled to each other through the fixing unit 150.

Unlike the structure shown in FIG. 3, the support frame 200 may have a structure capable of fixing the tunnel part 100 to the underside 3, and the concrete shape may be variously modified.

The vibration of the ground surface 2 due to an earthquake or the like caused by the ground is transmitted to the entrance portion 101 of the tunnel portion 100, 101 to the tunnel part 100. [

Particularly, the vibration, impact, deformation, etc. of the land surface 2 is largest at the entrance portion 101 and decreases as the tunnel portion 100 is farther from the land surface 2.

Therefore, in the present embodiment, in order to prevent the vibration, impact, deformation, and the like from the land surface 2 being directly transmitted to the tunnel part 100 so that the safety of the tunnel part 100 is not a problem, The spacing between the support frame parts 200 supporting the tunnel part 100 is different.

That is, the spacing between the support frame parts 200 is narrowed and the spacing between the support frame parts 200 is increased as the distance from the initial part 101 is increased.

Specifically, the first support frame part 201, the second support frame part 202, the third support frame part 203, the fourth support frame part 204, the fifth support part 202, Wherein a distance between the first and second support frame parts 201 and 201 is L1 and a distance between the first and second support frame parts 201 and 202 is L2, The interval between the second and third support frame portions 202 and 203 is L3 and the interval between the third and fourth support frame portions 203 and 204 is L4 and the interval between the fourth and fifth support frame portions 204 And 205 is L5, the support frame portions are provided so as to satisfy L1 < L2 < L3 < L4 < L5.

However, the support frame parts are spaced apart from each other at a maximum distance that can support the tunnel part 100 at a position away from the entrance part 101 by a predetermined distance and where the impact from the land is not transmitted, .

As described above, the support frame parts are disposed at a relatively narrow interval from the entrance part 101 to a position where the impact from the land is transmitted within a predetermined distance, so that the impact transmitted to the tunnel part 100 is maximized So that the safety of the tunnel part 100 can be improved.
