Submerged tunnel connecting system

The present invention relates to a submerged tunnel connection system that can maintain the waterproof function of the submerged tunnel in the event of an earthquake or displacement of the submerged tunnel due to an ideal action of the sea floor. In order to prevent the inflow of seawater, it is possible to separate and separate the compression plate and protective cap that secure the rubber gaskets that seal and seal the connection between the immersion box and the immersion box. The present invention relates to a sedimentation tunnel connection system which is easy to protect and installs a protective sheet at each corner of the settlement box to prevent damage and damage to the settlement box by interference between the settlement boxes.

Generally, submerged tunnels are structures constructed by immersing multiple submersible vessels underwater or undersea and then interconnecting each submersible vessel.

Here, a submerged tunnel connection system in which a sealing member, such as a rubber gasket, is inserted for waterproofing, and a fastening structure for fixing the rubber gasket is applied to the submerged box and the connection part of the submerged box.

In the process of installation of such a submerged tunnel, first, a submersible box formed of a tunnel structure is manufactured at a working yard on the ground, and then a plurality of submersible boxes are moved to a place for installing the submerged tunnel, and a work zone of a pre-arranged underwater or seabed is constructed. Sand is laid on top of it, and a number of settlements are arranged and installed at regular intervals on top of it, and dirt and stones are stacked outside the settlement tunnel to prevent damage.

In this case, iron gates are installed on both sides of the immersion tunnels connected to the plural settlements, and used as work passages, and rubber gaskets are installed at the connection portions of the settlements to prevent the inflow of seawater into the settlements.

As described above, after installing a rubber gasket for waterproofing each connection box connection part of the submerged tunnel installed underwater or undersea, the seawater filled inside the submerged tunnel is discharged to the outside, so that the water pressure inside and outside the submerged tunnel is By means of the car, the seam of each seam junction where the rubber gasket is installed is further strengthened, and the safety of the soak tunnel is strengthened and improved.

The installation work of these settlements is very important for both onshore and offshore installations, requiring complete preparation and careful work.

In addition, when connecting the submerged tunnel connection system, each submersible box and the submerged box are continuously connected by a rubber gasket and a fastening member for fixing the same, thereby preventing the inflow of seawater into the submerged box, and preventing earthquakes or other It should be designed and manufactured to have excellent new construction and watertight performance to maintain its function even in the event of earthquake caused by natural disaster.

Therefore, the performance of rubber gaskets installed in the submerged tunnel connection system and the fastening member for fixing them in the submerged tunnel connection system are very important factors for the safety of the submerged tunnel and are closely related to the lifetime of the submerged tunnel. have. That is, it is installed at the connection part connecting the submerged box and the submerged box, and the performance of the rubber gasket having elastic and compressive performance and the fastening member for firmly fixing and fastening the rubber gasket is very important. The role of the fastening member for fixing the rubber gasket in order to maintain the watertight performance between the boxes may be very important, and there is a demand for a sedimentation tunnel connection system that can withstand the displacement in the sedimentation tunnel due to the earthquake.

Accordingly, the present applicant has applied for a submerged tunnel connection system in the Republic of Korea Utility Model Registration No. 20-2006-0030100, the submerged tunnel connection system as shown in Figures 1 and 2, "multiple tunnels tunnels In the immersion tunnel connection system to form an immersion tunnel by connecting in the axial direction of the inclined end portion formed of a structure having an inclined surface on both opposite end surfaces of the first immersion box 111 and the second immersion box 112 are arranged adjacent to each other Connecting gaskets 144 having a plurality of pleats formed to allow contraction and expansion, and both end portions of the connecting gaskets 144 connected to the first and second ships 111 and 112, respectively; A fixing plate 133 for fixing both end portions of the gasket 144 to the first submerged box 111 and the second submerged box 112, and both ends of the connection gasket 144 to the first submerged box 111; ) And hitting anchors 122 respectively connecting to the second submarine 112 " We proposed a submerged tunnel connection system.

Here, the connecting gasket 144 is formed at both ends of the projections for preventing the departure from the two submersible boxes (111, 112) and the fixing plate 133 fixed at the axial displacement of the submersible boxes (111, 112), respectively. The fixing plate 133 has a cap-shaped protective cap 155 and a protective cap support 166 for protecting the connection gasket 144 from foreign matter.

In the immersion tunnel connection system as described above, the connection gasket 144 after placing the connection gasket 144 impregnated therein with the reinforcing material 145 at a predetermined position of the connection box between the immersion box 111 and the immersion box 112. The protective cap 155 is integrally formed in the), and the fixing plate 133 having a function of maintaining the watertight performance is pressed into the striking anchor 122.

At this time, the connection gasket 144 is excessively extended into the recesses 111 and 112 by the external pressure by the protection cap 155 integrally formed on the fixing plate 133, or the recesses 111 and 112. ) To protect the connection gasket 144 by the foreign matter flow therein.

In the immersion tunnel connection system as described above, in order to squeeze the connecting gasket, the fixing plate of the pressing member in which the fixing plate and the protective cap are integrally formed is simply a flat plane, and the fixing plate is fastened to the pressing portion of the connecting gasket. As a result of the structure, the contact cross section of the fastening member for coupling and fastening the fixed plate to the connecting gasket when the movement of the submarine occurs due to external high water pressure or fluctuations in the seabed is not only small but also has a flat structure. It is made of a structure that can reduce the there was a problem that can lead to a safety risk by shortening the life of the connection gasket is installed on the connection portion of the immersion box and immersion box.

On the other hand, in order to prevent breakage of the connection gasket which may occur at the connection part of the submerged box and the submerged box in the underwater or seabed, the connecting gasket is pressurized by the fixing plate of the crimping member to the inside of the submerged box. After the installation, the connecting gasket of the crimping member was press-installed with the fixing plate to connect to the other side of the splinter.

However, if the protective cap formed integrally with the fixing plate is large in the process of fixedly installing the connection gasket inside one side of the inlet box, the connecting gasket protrudes out of the inlet box and damages the connection gasket when the other inlet box is installed. This may occur, and because of this, there is a problem in that the connection gasket needs to be replaced or reinstalled. At this time, the replacement and reinstallation of the damaged connection gasket installed in the submarine can not be carried out underwater or undersea. Therefore, after moving and transporting the submarine installed underwater or undersea again to the land, replace the damaged connection gasket in the marine submarine or Since it has to be reinstalled, there were problems such as high cost, time consuming, and delay in working process.

In order to solve the problems as described above, if the size of the protective cap integrally formed on the fixing plate is reduced, the gap between the protective cap installed in one of the submarines and the protective cap installed in the other submarines is widened so that the connection gasket There was a problem that the protective cap for protecting the does not perform its function.

Here, the pressing member is manufactured and formed integrally with the protective cap and the fixing plate, so if the protective cap is damaged or damaged, it is impossible to replace the protective cap alone, so the pressing member to which the protective cap and the fixing plate are integrally connected must be replaced. When releasing the crimping member to which the protective cap and the fixing plate are integrally connected, a high water pressure is generated between the connection gasket and the end surface of the needle box, and a leak occurs inside the needle box due to the high pressure generated. There is a concern that the connection gasket is damaged and broken, which has a problem that may affect the safety of the workers working in the submerged tunnel installed underwater and undersea, which may cause a safety accident.

On the other hand, due to the change of working conditions and the carelessness of the crane worker and general worker who move and transport the container, when the connection between the container and the container is carried out, the container and the container are often collided with each other. And when the degree of damage is severe, not only a lot of time and money is consumed, such as having to re-work again, there was a problem that can not comply with the construction schedule.

The present invention has been made to solve the problems as described above, in order to prevent the inflow of seawater when connecting a plurality of neighboring submarines to fix the rubber gasket for sealing and sealing the connection between the submarines and submerged It is possible to replace and reinstall the protective cap only when the protective cap is damaged or damaged by dual separation of the pressing plate and the protective cap, which does not affect the performance of the rubber gasket and also the overall weight of the pressing plate.
