Description

TECHNICAL FIELD [0001] The present invention relates to a flooded deep-sea tunnel structure having a self-buoyancy control function, an operating system thereof, and a method of operating the same.

The present invention relates to a floating deep-sea tunnel system. More particularly, the present invention relates to a floating deep-sea tunnel system having self-buoyancy control capability, minimizing load on an external support structure, and improving stability.

The geographical feature surrounded by the sea on three sides and the importance of expanding the nationwide transportation network are emerging. Recently, the construction of the Daegyo Bridge with the tunnel structure of Geoje Island has been completed and the interest in the marine transportation infrastructure is gradually increasing. In particular, the underwater tunnels of Jeju-Mokpo are being publicized, and mega-projects such as submarine tunnels in Korea, China and Korea are being discussed in detail. Therefore, interest in ocean transportation infrastructure and research and development are urgent.

Figure 1 shows the four types of marine transportation infrastructure and the distinction according to the four support methods of underwater tunnels. Marine transportation infrastructure can be classified into bridges, underwater (underwater) tunnels, immersion tunnels, and submarine tunnels. In terms of construction time and cost, underwater tunnels are more advantageous than the other three kinds of marine transportation infrastructure many. Underwater (underwater) tunnels are less influenced by submarine weather, including earthquakes and earthquakes in the seabed, without the effects of winds and waves on the surface of the water. That is, by constructing the tunnel in the water rather than the sea surface or the sea floor, which is a relatively severe construction environment, it is possible to maximize the workability and to operate the tunnel in a stable natural environment even after the construction. Bridges, immersion tunnels, and submarine tunnels are fixed on the surface of the seafloor or on the ground. However, underwater (underwater) tunnels are floated on the surface of the seabed.

The factor that distinguishes the four support systems supporting underwater (underwater) tunnels is the difference between the buoyancy (B) and the self weight (W) of the underwater tunnel body. If the buoyancy is larger than its own weight, a force to float on the sea surface occurs. If its weight is larger than buoyancy, the force of sinking to the bottom of the sea becomes larger. Therefore, if the buoyant force is large, a method of fixing the tunnel body to the bottom of the sea floor should be used. If the weight of the tunnel body is large, it is possible to mount the tunnel body on the sea water surface or mount the bridge on the sea floor. If the self weight and the buoyancy are the same, theoretically, an external support device is unnecessary.

In the water (underwater), there is always a risk of safety accidents caused by huge water pressure. In addition, although the natural environment is relatively stable compared to sea level and seabed ground, oceanic currents due to large-scale climate change such as seasons have never been so small in physical effects on large structures such as tunnels. That is, in the construction of underwater (underwater) tunnels, it is a very important construction technology factor to maintain the stable body position according to the supporting method of the tunnel body.

Considering the convenience of construction, construction period, difficulty of construction, cost, etc., it can be concluded that underwater (underwater) tunnels are relatively advantageous for future marine transportation infrastructure. Therefore, it is very urgent to develop an underwater (underwater) tunnel construction technique that can secure the convenience of construction and stability after construction. By doing so, it will greatly contribute to the improvement of Korea's marine infrastructure technology, which has little experience in construction of underwater (underwater) tunnels, immersion tunnels and submarine tunnels except for bridges.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the detailed description of known functions and configurations incorporated herein will be omitted when it may unnecessarily obscure the subject matter of the present invention.

The same reference numerals are used for portions having similar functions and functions throughout the drawings. Throughout the specification, when a part is connected to another part, it includes not only a case where it is directly connected but also a case where the other part is indirectly connected with another part in between. In addition, the inclusion of an element does not exclude other elements, but may include other elements, unless specifically stated otherwise.

Hereinafter, the structure and functions of a floating deep-water tunnel system according to an embodiment of the present invention will be described.

2 is a schematic view of a floating deep-water tunnel structure having a self-buoyancy control function according to an embodiment of the present invention, and a sectional view of the tunnel.

As shown in FIG. 2, the floating deep-water tunnel structure according to an embodiment of the present invention may include a tunnel body 100, a floating suspension system A, and an immersive suspension system B.

The tunnel body 100 may include a distribution passage passage 110 through which a quantity of goods can pass and a hollow section 120 through which seawater can flow to control the buoyancy of the tunnel. The distribution passage unit 110 may include roads, railways, and / or delivery vehicles on which human physical and / or material move. The volume of the hollow section 120 can be designed in consideration of the self weight of the tunnel body 100 and the buoyancy caused by the air in the distribution passage section 110.

An external tunnel support system that supports the tunnel body 100 may include a suspended suspension system A and an immersive suspension system B. The suspended suspension system A may comprise a float 200, a floating suspension line 210 and a suspended suspension 220. The suspended suspension system B may comprise a lower mooring 300, a floating suspension line 320, , And a seaweed suspension 330 (Fig.

The suspended suspension system A and the suspended suspension system B can function to fix the tunnel body 100 vertically and horizontally using the suspension wires 210 and 310 and the suspension members 220 and 320.

The float 200 can determine the number of floating bodies 200 according to the length of the tunnel body 100. By using the floats 210, a small number of floating floats can uniformly apply a floating force to the entire tunnel body 100. [ . The underwater environment can be said to be relatively constant and stable compared to the ocean surface and the sea floor, but the power of hydrostatic pressure is not easy to overcome. In the design of the tunnel body 100, it may be desirable to design the tunnel body 100 so that there is no problem in operation even if the tunnel body falls down to a depth greater than the depth of the tunnel body 100. However, It is the purpose of the floating system to avoid sinking to the ground. Therefore, if the floatation system A has to apply a floating force enough to support the self weight of the tunnel body to the tunnel body and directly connect the float 200 to the tunnel body 100, The quantity can be increased. In this case, the construction period is lengthened and the cost is increased, and a huge floating body is always installed on the sea, which can be a great obstacle to vessel movement.

As shown in FIG. 2, when the tunnel body mounting method using the floating suspension line 210 and the suspended suspension 220 is used, the number of the float 200 is reduced as described above, However, installation of tunnels can reduce the impact on the sea. In addition, as compared with the method of connecting the floating body directly to the tunnel body 100 by mounting the floating suspension member 220 and mounting the floating suspension body 100, floating force can be easily dispersed and applied to the tunnel body 100 can do.

The immersion suspension system functions to fix the tunnel body 100 so that it does not rise to the water surface, and functions opposite to the suspended suspension system. The immersion suspension line 310 is connected to the lower mooring 300 fixed to the seabed ground and the immersion suspension 320 is connected to the immersion suspension line 310 so that the tunnel body 100 is fixed And the like.

As can be seen from FIG. 2, the tunnel body applied to the floating deep-water tunnel structure having the self-buoyancy control function according to an embodiment of the present invention forms an artificial air gap therein, When the natural environment including the sea current and the sea breeze is stable, the buoyancy force (B) and the weight (W) can be made equal to each other by adjusting the buoyancy of the buoyant force, and the buoyant suspension system (A) The tunnel can be operated stably even in an unpredictable natural environment. Further, since the tunnel body 100 has a function of adjusting the buoyancy of the tunnel body 100, the loads of the suspended suspension system A and the suspended suspension system B, which are the external support systems, can be remarkably reduced and the size of the structures other than the tunnel body 100 By reducing the number, the impact on the environment can be minimized and the impact due to natural environmental factors can also be reduced.

3. FIG. 3 is a schematic view of a floating deep-water tunnel structure having a self-buoyancy control function and a tunnel cross-sectional view with a hanger 130 according to an embodiment of the present invention.

 As shown in FIG. 3, the tunnel body 100 of the deep-sea tunnel structure according to the present invention can be divided into a plurality of tunnel unit bodies 140. That is, the tunnel unit body 140 may be manufactured on land and assembled in water, or a plurality of tunnel unit bodies may be assembled on land to move into the water.

The hanger 130 shown in FIG. 3 is a kind of structure of a cradle function installed on the outer surface of the tunnel body. When the suspended suspension 220 is connected to a specific connection point of the tunnel body 100, the floating force is concentrated at the fixed point. If the connecting point connecting the different materials is concentrated, the connecting point of the tunnel body 100 may be damaged because it can not overcome the force. As shown in FIG. 3, the hanger 130 surrounding half of the tunnel body functions to uniformly distribute the floating force from the suspension member to the tunnel body half. The hanger 130 may be disposed through the inner surface of the tunnel body 100 and may be fixed at a plurality of positions to prevent movement in the axial direction while being disposed on the outer surface of the tunnel body 100.

FIG. 4 is a cross-sectional view of a tunnel body of a floating deep-water tunnel structure having a self-buoyancy control function, in which a unit hollow section is formed according to an embodiment of the present invention.

As shown in FIG. 4, the hollow section of the tunnel body, which can be applied to the deep-sea tunnel structure according to an embodiment of the present invention, can be separated into unit hollow sections.

Depending on the situation, the flow of seawater into the hollow section to control buoyancy should be very rapid. As shown in FIG. 2, the hollow section integrally formed may take a long time to inflow and discharge seawater. By disposing the hollow section 120 in a unit hollow hollow section having a small volume, it is possible to cope with the harshness of the buoyancy control by simultaneously operating the inflow and outflow of seawater into the unit hollow hollow sections.

Further, as shown in Fig. 2, the integral hollow sectional structure has difficulty in adjusting the buoyancy as necessary. In the case where the buoyancy is decreased by the inflow of seawater and the self weight is increased, when a certain amount of seawater is introduced into the integral hollow section shown in Fig. 2 and the required buoyancy is adjusted, the tortuosity of the tunnel body Or may interfere with the stability of the tunnel, leading to serious accident situations. As shown in FIG. 4, by forming the hollow section into a plurality of unit hollow sections, it is possible to control the inflow and outflow of seawater to a unit hollow section at a required position, and thereby the required buoyancy can be stably controlled.

In addition, a hollow section switch 121 and a seawater inflow passage 122 may be provided for adjusting the unit hollow section shown in FIG. 4. When air is injected into the hollow section to increase buoyancy,

The unit hollow cross section shown in Fig. 4 can also be formed in the axial direction of the tunnel. That is, the tunnel unit body shown in FIG. 3 can be formed by dividing the hollow section in the axial direction of the tunnel into a unit hollow section.

FIG. 5 is a view showing a hanger installation direction of a tunnel sectional view of a floating deep-water tunnel structure having a self-buoyancy adjusting function in which a hanger according to an embodiment of the present invention is installed.

The hanger 130 shown in FIG. 3 can be connected to a vertical line located vertically. In the floating deep-water tunnel structure according to an embodiment of the present invention, a floating force can be applied by connecting to a floating line . Similarly, when the direction of the hanger 130 is changed as shown in Fig. 5, it can be connected to a vertical line extending downward or laterally. It can be applied to a function of supporting excessive floatation force when it is connected to the immersion suspension 320 of the immersion suspension system (B).

FIG. 6 illustrates a floatation fixation method in a floating deep-water tunnel structure having a self buoyancy control function according to an embodiment of the present invention.

The float (200) is a device for applying floating force to the tunnel body (100), and it should remain floating on the water surface. However, due to weather phenomena caused by typhoons and storms, and tsunami caused by earthquakes such as earthquakes, the water level can rise temporarily. In the floating deep sea tunnel structure according to an embodiment of the present invention, the tunnel body 100 is fixed at a certain depth by floating and immersion suspension systems A and B. If the floating body is not fixed to the sea floor during the above-mentioned natural phenomenon, it will rise along the sea surface, and excessive load may be applied to the tunnel body and float itself. Therefore, by fixing the float to the bottom of the seabed, the float 200 can be fixed to the sea surface at a normal time, and a certain floating force can be applied to the tunnel body. In addition, by preventing lateral movement of the float itself, the influence of horizontal currents can also be minimized.

FIG. 7 shows a layout of a buoyancy measurement sensor and a self-weight variation prediction sensor in a floating deep-sea tunnel structure having a self buoyancy control function according to an embodiment of the present invention.

The deep-sea tunnel structure according to an embodiment of the present invention is provided with a hollow section so that it has a self buoyancy control function. The purpose of use of the tunnel is to carry out various kinds of logistics or human movements, and the weight of the tunnel must change every moment according to the flow of the goods using the moving tunnel. Therefore, even if the hollow section has a buoyancy control function, it is necessary to continuously check the buoyancy state of the tunnel, calculate the buoyancy control amount, and continuously control the inflow of seawater into the hollow section with the calculated buoyancy control amount. For this purpose, it is necessary to arrange the devices 150, 151, 152 for measuring the physical quantity capable of estimating the buoyancy force at necessary positions.

Buoyancy can be estimated by measuring the weight of the tunnel body. However, in order to measure the weight of a tunnel body suspended in water, a fixed structure is required. By applying the float fixing system as shown in FIG. 6 and the hanger shown in FIG. 3, the weight of the tunnel body can be measured. 3, the weight of the tunnel body can be measured when the weight of the tunnel body is larger than the buoyancy. In the same manner, buoyancy can be measured when the buoyant force of the tunnel body is larger than its own weight when the hanger system and the immersion suspension as shown in Fig. 5 are applied.

Alternatively, buoyancy versus self weight of the tunnel body may be estimated by measuring the tensile force applied to the suspension line. It is possible to measure the weight of the tunnel body at all installed positions by attaching a device capable of measuring the tension of the suspension material to the suspension line. By applying both the suspension suspension material and the immersion suspension material, It is possible to measure the balance state between the pressure and the pressure.

In addition, the state of the levitation force can be estimated by measuring the axial linearity of the tunnel. Typical suspension wires can use metallic wire with a certain amount of tension. Therefore, the tunnel body may be warped vertically and horizontally due to its own weight and buoyancy. Particularly, since the ratio of the buoyancy to the self weight may vary depending on the position of the tunnel body ranging from tens to hundreds of meters, the tunnel body can not always maintain the linearity. Therefore, by confirming the linearity of the tunnel, it is possible to estimate the buoyancy and self-pressurized state of the tunnel body.

Alternatively, as mentioned above, it is possible to calculate the weight of the tunnel by measuring the amount of logistics remaining in the tunnel. The weight of a tunnel can change when the amount of traffic flowing into the tunnel increases or decreases. In recent years, image analysis technology has been developed, and the number of vehicle movements at a specific point can be measured automatically in real time. Therefore, it is possible to estimate the number of vehicles entering and leaving the tunnel entrance, the size of the vehicle, etc., calculate the remaining logistics in the tunnel, and estimate the change in the buoyancy and the autonomous pressure of the tunnel in an approximate manner.

As shown in FIG. 7, when such a sensor is installed for each tunnel unit body, buoyancy and self-pressurized state of the tunnel body can be confirmed.

Particularly, it is possible to confirm the distribution of buoyancy and self-pressure in the direction of the tunnel axis by connecting the sensors installed in the direction of the tunnel axis in a daisy chain manner and assigning a unique number to each position of the sensor, and more effective and quick buoyancy control Is possible.

Another very important factor in deep-sea tunnels is safety management. Under water, high water pressure always works. In addition to flooding accidents, small fire accidents can also have catastrophic consequences. Therefore, it is very important to have a safe operating system that can detect accidents in advance and minimize the damage to the tunnel body which can reach to several Km.

FIG. 8 shows the arrangement of the safety situation measuring sensor 160 and the safety facility sections 171 and 172 in the floating deep-sea tunnel structure having the self-buoyancy adjusting function according to an embodiment of the present invention.

Safety situation measurement sensors may include temperature, water pressure measurement sensors. The safety situation measurement sensor may be mounted inside the tunnel, preferably distributed from the outside of the tunnel to the center of the tunnel. Also, as shown in FIG. 8, it is possible to arrange a plurality of safety situation measurement sensors for each tunnel unit section.

The safety facility zone shown in FIG. 8 can be divided into a breaking zone 171 and a blocking zone 172. The blocking area is a device for isolating each tunnel unit body from adjacent adjacent tunnel unit bodies, and may include a waterproof, fire-blocking facility with pressure resistance. The destruction zone is the zone where the demolition facility destroys the tunnel. As mentioned above, fire and submergence accidents in the deep sea can be very lethal and, in some situations, can lead to a situation that can not be tolerated. In this imminent situation, the last option to minimize damage is to separate the tunnel unit body from the accidental tunnel body. The quickest way is to destroy the outer wall of the tunnel at a specific location. In the event of a collapse, the destroyed area containing the explosive is instantly destroyed in the event of a collision, whereby the accidental tunnel unit body is separated from the adjacent tunnel unit body. Before the destruction zone is destroyed, the interception facility of the interception zone of the adjoining tunnel unit body has already been activated.

FIG. 9 is a conceptual diagram illustrating a state in which a failure zone is destroyed in a floating deep-sea tunnel structure having a self buoyancy control function according to an embodiment of the present invention. The tunnel unit body, which has been destroyed by the destruction zone, is fixed to the floating, immersed suspension system (A.B) and does not sink to the surface of the seabed so that the subsequent survival structure work and restoration work can be facilitated.

10 is a block diagram of a buoyancy control system of a floating deep-sea tunnel structure having a self-buoyancy control function according to an embodiment of the present invention.

As shown in FIG. 10, the buoyancy control calculation unit, which has received the measured value from the buoyancy measuring device installed in the tunnel body, calculates the buoyancy control amount T0 required at the time when the measured value is measured based on the measured value. The buoyancy control calculation unit stores the calculated buoyancy control amount in the internal memory and transmits it to the hollow section opening / closing control unit. The hollow section opening / closing control section calculates the opening / closing amount of the used section based on the buoyancy control amount and operates the hollow section opening / closing device. The buoyant force of the tunnel body changes, and the buoyancy measuring device transmits the measured value at T = T1 back to the buoyancy control calculation section. The buoyancy control calculation unit calculates the buoyancy control amount at T1 and compares it with the already stored buoyancy control amount. If it is determined that there is the buoyancy control effect based on the T0 buoyancy control amount, the T1 buoyancy control amount is transmitted to the hollow section opening and closing controller and the buoyancy control is resumed. The floating deep-water tunnel buoyancy control system according to an embodiment of the present invention forms a feedback loop that results in buoyancy measurement, buoyancy control amount calculation, and hollow section buoyancy control. If it is determined that the buoyancy control effect at T0 does not appear at T = T1, an alarm signal is transmitted to the tunnel manager.

When the buoyancy and the pressure control of the large structure such as the tunnel body are normal, it is one of the essential factors for stable tunnel body operation. However, if there is a problem with the operation or if a fault occurs in the measurement system, the buoyancy control is infinitely amplified to the error value, which is a dangerous factor with a great deal of power to destroy the entire tunnel system. Therefore, its own buoyancy control function should always be monitored and operated under the supervision of the administrator.

The buoyancy control system shown in FIG. 10 can be applied to operate the buoyancy control function according to an embodiment of the present invention stably.
