{Transport system using submerged floating tunnels}

The present invention relates to a logistics transportation system using an underwater tunnel. More specifically, it is possible to reduce logistics transportation costs to the Eurasian continent by enabling transportation through an underwater tunnel using an unmanned locomotive driven by a battery. At the same time, by installing a hollow pipe that allows algae to pass through on the outside of the underwater tunnel, the durability of the underwater tunnel can be improved by reducing the lateral pressure applied to the underwater tunnel by tidal currents, as well as preventing safety accidents caused by tidal currents. This is about a logistics transportation system using an underwater tunnel that reduces the risk of occurrence.

In general, undersea tunnels that pass through the bottom of the ocean, rivers or streams are provided by submerging the tunnel enclosure into the underwater bottom or by placing it on top of a foundation structure installed on the underwater bottom to cross the water.

This type of submarine tunnel, unlike the type excavated into the seabed rock, is installed on the underwater floor or across the water, and consists of a precast tunnel housing sunk in the water.

Meanwhile, in recent years, underwater tunnels supported by buoyancy that can minimize construction costs and construction periods have been studied, and examples of such underwater tunnels have been disclosed in Korean Patent Nos. 10-0797795 and 10-0797796. . In other words, by constructing an underwater tunnel supported by buoyancy at a certain depth underwater, the construction cost and construction period can be minimized by being manufactured on land and then assembled underwater without being affected by ocean waves or wind.

In general, underwater tunnels can be designed in a way to avoid deep trenches or orogenic zones. For example, it can be seen as a concept of breaking through to the seawater at a point where it is no longer possible to penetrate the seafloor, or at a point where a trench or orogenic zone can be completely avoided, and connecting it to an underwater tunnel.

Such an underwater tunnel is a method of placing a tunnel structure in the water by appropriately controlling gravity and buoyancy, and generally uses four methods: tension leg, pontoons, column support, and free. It can be configured by appropriately combining it depending on the section.

These underwater tunnels had the problem of being vulnerable to lateral forces caused by currents, etc.

In addition, recently, there has been discussion about a continental railway connecting the Korean Peninsula with China, Central Asia, Russia, and Europe. If such a continental railway becomes a reality, it will not only reduce logistics costs, but also save more natural resources. It is expected that significant economic benefits will be achieved, including stable security.

Since North Korea must be included in the route of this continental railway, the connection of the North-South railway must be established in advance for the continental railway to become a reality. However, the realization of the connection of the North-South railway is far away, and even if the North-South railway is connected, the operation of the railway Since it is difficult to expect that this will happen normally, a new logistics transportation method to the Eurasian continent is being required.

The present invention enables transportation through an underwater tunnel using an unmanned locomotive driven by a battery, thereby reducing logistics transportation costs to the Eurasian continent and at the same time allowing birds to pass through the outside of the underwater tunnel. A logistics transportation system using an underwater tunnel that not only improves the durability of the underwater tunnel by reducing the lateral pressure applied to the underwater tunnel by tidal currents by installing hollow pipes, but also reduces the risk of safety accidents caused by tidal currents. Regarding (50), as shown in FIGS. 2 to 7, its configuration largely consists of a railway vehicle 200 running on the underwater tunnel 100 and a hollow pipe provided on the outside of the underwater tunnel 100 ( 300).

In more detail, the underwater tunnel 100 consists of a plurality of units having a certain length connected to each other, and can be supported in a buoyant state by a support means 110 such as a chain fixed to the underwater bottom. there is.

In addition, inside the underwater tunnel 100, passages 130a and 130b are formed in the longitudinal direction, partitioned by a partition wall 120 that can be used as an evacuation passage or management passage, and the passages 130a and 130b are It may be provided with a rail 140 along which the railway vehicle 200 moves. As the structure of the underwater tunnel 100, which allows the railway vehicle 200 to move inside, is known, a detailed description thereof is provided. Decided to omit it.

Meanwhile, the railway vehicle 200 runs inside the underwater tunnel 100, is towed by an unmanned locomotive (not shown) driven by a battery, and is pulled by the unmanned locomotive (not shown) and loads logistics. It may include multiple freight cars (not shown) being transported.

The unmanned locomotive (not shown) is configured to operate only inside the underwater tunnel 100, and the plurality of freight cars (not shown) can be towed by a normal locomotive outside the underwater tunnel 100.

That is, outside the underwater tunnel 100 located in the continental area, freight cars loaded with logistics are towed and transported by a normal locomotive, and the transported freight cars are transported to the underwater tunnel at a transshipment center provided before entering the underwater tunnel 100. (100) Connected to an unmanned locomotive (not shown) operating inside, so that freight cars (not shown) are transported inside the underwater tunnel (100) only by the unmanned locomotive (not shown) for the underwater tunnel (100). It can be configured.

In addition, after passing through the underwater tunnel 100, the freight car loaded with logistics at a transshipment center located in the continental region is connected to a normal locomotive and operated, thereby enabling continuous transportation of logistics in the continental region. Of course it exists.

Next, the hollow pipe 300 is configured to reduce the lateral pressure caused by the tidal current applied to the underwater tunnel 100, and is installed in the width direction on either the upper or lower outer side of the underwater tunnel 100. That is, it can be installed in a direction perpendicular to the installation direction of the underwater tunnel 100.

Therefore, by allowing the current flowing in the direction of the underwater tunnel 100 to pass through the hollow pipe 300, the lateral pressure applied to the underwater tunnel 100 by the current can be reduced.

That is, when the hollow pipe 300 is installed in a direction perpendicular to the installation direction of the underwater tunnel 100 on either the upper or lower side or the upper or lower outer side of the underwater tunnel 100 as described above, as shown in FIG. 2 As shown, in the current surrounding the underwater tunnel 100, a flow is generated that tries to pass through the hollow pipe 300, which has a relatively narrow passage area, according to Bernoulli's principle, and the lateral pressure applied when the current hits the outside of the underwater tunnel 100. By reducing this, the underwater tunnel 100 can be maintained in a more stably installed state.

At this time, the hollow pipe 300 can be installed in the underwater tunnel 100 by a fixing means 310 such as a wire or chain, and flows in the lateral direction, that is, in a state fixed to the underwater tunnel 100. It is desirable to minimize the pressure generated by the current passing inside the hollow pipe 300 from being transmitted to the underwater tunnel 100 by installing it to allow flow in the left and right directions to some extent.

For example, a fixing groove 302 of a certain width is formed in the longitudinal direction of the hollow tube 300 so that the fixing means 310 can be inserted into the fixing groove 302, thereby fixing the fixing means 310. It is possible to prevent the departure of .

In addition, as shown in FIG. 3, the width of the fixing groove 302 is formed to be wider than the thickness of the fixing means 310 to allow some degree of movement of the fixing means 310 inside the fixing groove 302. It can be configured to do so.

Accordingly, when pressure is applied to the hollow pipe 300 due to the inflow of algae, the hollow pipe 300 can flow within the flow range of the fixing means 310, so the pressure transmitted to the underwater tunnel 100 can be minimized.

In addition, a fixing pin 320 is installed in the center of the hollow pipe 300 in contact with the underwater tunnel 100, so that the underwater tunnel 100 and the hollow pipe 300 can be coupled by the fixing pin 320. By doing so, the hollow pipe 300 is additionally fixed so that it does not escape from the underwater tunnel 100, and at the same time, the pressure applied from the tidal current passing inside the hollow pipe 300 is moved in the lateral direction, that is, in the left and right directions. It may be structured to support the meeting.

Meanwhile, the underwater tunnel 100 may be provided with blocking members 400 at regular intervals so that some sections can be closed when water leakage occurs inside.

At this time, the blocking member 400 is provided on the inner upper side of the underwater tunnel 100 and is lowered when a water leak occurrence signal is received.

In addition, as shown in (a) and (b) of FIG. 6, the blocking member 400 is made of a multi-stage structure such as a step shape or an antenna shape, and is normally overlapped and has a small volume, so it is used in the upper space inside the underwater tunnel. It is easy to store, and when used, the multi-stage structure can be deployed downward to block the inside of the tunnel.

In addition, a guide groove 160 is formed on the inner wall of the section where the blocking member 400 is installed, so that the blocking member 400 can stably descend along the guide groove.

In addition, as shown in Figure 5, when water leakage occurs inside the underwater tunnel 100 and the blocking member 400 operates, the lower end of the blocking member 400 is on the bottom of the underwater tunnel 100. Water leakage can be blocked more completely by removing some of the structures such as the installed rail 140 and inserting them into the seating groove 150 formed at the corresponding location.

At this time, a packing member (not shown) made of silicone, rubber material, synthetic resin material, etc. is provided around the inner peripheral surface of the seating groove 150 and the guide groove 160 and the blocking member 400 in contact therewith to further enhance the sealing force. It can also be configured to improve.

Meanwhile, as shown in FIG. 7, a plurality of hollow pipes 500 may be installed in the internal idle space of the underwater tunnel 100, and the hollow pipes 500 may be utilized for the transportation of various logistics.

In other words, the first hollow pipe 510 installed in the upper idle space of the underwater tunnel 100 can be used for mail transportation using capsules, and the inside of the first hollow pipe 510 is maintained in a vacuum state. By doing so, it can be configured to minimize the components required for mail transportation through the first hollow pipe 510 and at the same time improve the reliability of mail transportation.

In addition, second and third hollow pipes 520 and 530 may be installed in the lower idle space of the underwater tunnel 100, and the second and third hollow pipes 520 and 530 are respectively an oil pipeline for transporting oil and a natural It can be used as a natural gas pipe to transport gas.

In addition, the first, second, and third hollow pipes 510, 520, and 530 can be buried and installed in an idle space of the underwater tunnel 100 that is filled and finished with concrete, etc.

Therefore, according to the logistics transportation system 50 using an underwater tunnel according to the present invention as described above, transportation can be carried out through the underwater tunnel 100 using an unmanned locomotive driven by a battery to the Eurasian continent. It is possible to reduce logistics transportation costs and install a hollow pipe (300) that allows birds to pass outside the underwater tunnel (100) to reduce lateral pressure caused by birds and reduce logistics costs with the Lasia continent. Natural resources such as oil and natural gas can be stably secured at a lower cost, and the lateral pressure applied to the underwater tunnel 100 by tidal currents can be reduced, thereby improving the durability of the underwater tunnel 100. It has various advantages such as not only being able to do so, but also improving the safety of marine transportation.

Although the preferred embodiments of the present invention have been described above, the scope of the rights of the present invention is not limited thereto, and the scope of the rights of the present invention extends to the scope substantially equivalent to the embodiments of the present invention. Various modifications can be made by those skilled in the art without departing from the above.

The present invention relates to a logistics transportation system using an underwater tunnel. More specifically, it is possible to reduce logistics transportation costs to the Eurasian continent by enabling transportation through an underwater tunnel using an unmanned locomotive driven by a battery. At the same time, by installing a hollow pipe that allows algae to pass through on the outside of the underwater tunnel, the durability of the underwater tunnel can be improved by reducing the lateral pressure applied to the underwater tunnel by tidal currents, as well as preventing safety accidents caused by tidal currents. It is about a logistics transportation system using an underwater tunnel that reduces the risk of occurrence.
