Description

Technical Field

[0001] This invention relates to the field of tunnel drainage technology, and in particular to a tunnel drainage device and its construction method. Background Technology

[0002] Tunnel drainage systems are facilities used to collect and remove water accumulated inside tunnels. Their purpose is to keep tunnels dry and ensure the safety of tunnel structures and traffic.

[0003] A drainage device for preventing blockages in highway tunnels, disclosed in Chinese Utility Model Patent Application Publication CN222686734U, collects debris in the water while draining it. However, this device uses filters inside the drainage pipe to isolate gravel, which requires manual cleaning periodically. This increases labor and economic costs for the tunnel section. Furthermore, a large accumulation of gravel on the filters can impede drainage, affecting the device's effectiveness and the tunnel's normal drainage. The size of the drainage pipe is also unique, and its design is mostly based on conventional conditions. In extreme weather or special construction scenarios, it may fail to drain properly, leading to significant water accumulation in the tunnel, hindering normal vehicle traffic, and increasing pressure on traffic and municipal management. Therefore, this application provides a tunnel drainage device and its construction method to meet these needs. Summary of the Invention

[0014] A construction method for a tunnel drainage device includes the following steps: Step 1: Water in the tunnel flows into the gravel disposal module through the first rain grate. The gravel flowing in with the water is crushed in the gravel disposal module. The crushed gravel will be smaller in volume. The smaller gravel will follow the water flow into the pipe module and then be discharged into the municipal pipe network. In extreme weather conditions, when the flow rate is large, the gravel will be diverted through the pipe module after being processed in the gravel disposal module, reducing the probability of backflow caused by the inability of a single-diameter pipe to handle a large flow of water. Step 2: The first opening plate is opened by the mushroom-shaped top, allowing water to enter the porous cylinder, thus adding water to the water-filled counterweight box and increasing its weight. After the water-filled counterweight box is increased in weight, it pulls the steel wire rope to move on the first or second fixed pulley, which in turn lifts the lower pressure box. The short column opens the second opening plate, allowing water to flow out of the water-filled counterweight box, reducing its weight and causing the lower pressure box to fall. Water is then added to the water-filled counterweight box, and the lower pressure plate presses down, causing the crushed stone plate to crush the crushed stone. The processed crushed stone is discharged into the second drain through the isolation net. Step 3: Under normal weather conditions, the treated gravel follows the water flow into the fourth U-shaped plate. Because the water flow is not large, it directly enters the external municipal pipe network through the first rigid pipe, corrugated pipe, elbow, and first inlet pipe. In extreme weather conditions, the gravel in the turbulent water flow will also be treated. The turbulent water flow has a large impact force, and the fourth U-shaped plate also contains a lot of water. Under the pressure of the impact force and weight, the impact pressure plate moves vertically on the vertical cylinder through the vertical cylinder adapter, so that the water can be diverted. This eliminates the need to worry about the pipe being unable to drain or not draining properly. The second spring ensures the support force of the impact pressure plate under normal conditions.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a crushed stone disposal module, the device can crush the crushed stone into extremely small particles, which can then flow with the water into the normal municipal pipe network without clogging the filter system of the municipal pipe network. This eliminates the need for regular manual cleaning of the device, which reduces the amount of manual labor and the economic expenditure of the tunnel to a certain extent. At the same time, the extremely small particles will not affect the normal water intake and drainage of the device, nor will they affect the filtration and drainage system of the municipal pipe network. This reduces the possibility of poor drainage and disruption of normal tunnel drainage caused by the accumulation of large crushed stones.

[0016] By setting up pipeline modules, after the device is installed in the tunnel, it can automatically distribute the water flow according to the amount of water entering the device after extreme weather occurs. This allows the water in the tunnel to be discharged smoothly, which reduces the probability of vehicles being unable to pass through the tunnel normally due to the pipeline flow not matching the water flow under extreme weather conditions. This also reduces the pressure on traffic and municipal command to some extent. Attached Figure Description

The wire rope 311 is placed on the first fixed pulley 308 and the second fixed pulley 310. Cylindrical lead block 312 and cylindrical iron block 313 are welded to both ends of steel wire rope 311.

[0035] Water in the tunnel first enters the gravel disposal module 3 through the first rain grate 2. Part of the water first enters the second rain grate 302 on the first U-shaped plate 301, and the other part of the water is diverted to the first U-shaped plate 301 through the triangular diverter plate 303. The diverted water enters the porous cylinder 316 after the mushroom head 317 pushes open the first opening and closing plate 305, and then enters the water injection counterweight box 315 to add weight to the water injection counterweight box 315. When the weight of the water injection counterweight box 315 increases, the water injection counterweight box 315 will press down. After the water injection counterweight box 315 presses down, the wire rope 311 and the first fixed pulley 308 or the second fixed pulley 310 move down, thereby lifting the components such as the pressure box 321. When the water-filled counterweight box 315 falls onto the square groove on the second U-shaped plate 327, the short column 329 will push open the second opening plate 320, and the water in the water-filled counterweight box 315 will fall into the third U-shaped plate 330 through the water leakage hole on the square groove. When the weight of the water-filled counterweight box 315 is gone, the pressure box 321 will fall directly into the water in the third U-shaped plate 330. The water enters the pressure box 321 through the water injection hole. As the water in the pressure box 321 gradually increases, the weight above its pressure plate 324 increases, and the pressure plate 324 presses down, thereby driving the crushed stone pressure plate 326 to crush the crushed stone in the third U-shaped plate 330. When the water-filled counterweight box 315 is refilled with water, it will pull up the pressure box 321 again. The water in the pressure box 321 will be discharged through the outlet hole, thus restoring the pressure plate 324 to its original state. The inclined plate 331 of the third U-shaped plate 330 is responsible for letting the gravel flowing into the water in the third U-shaped plate 330 roll onto the horizontal surface of the third U-shaped plate 330. The isolation net 333 is responsible for isolating the larger gravel, waiting for it to be crushed again. The smaller gravel will pass through the isolation net 333 with the water flow and then be flushed into the pipe module 4 from the second drain, and enter the municipal pipe network through the pipe module 4.

[0036] By incorporating the gravel disposal module 3, the device can crush gravel into extremely small particles, allowing it to flow into the municipal pipe network without clogging the network's filter system. This eliminates the need for regular manual cleaning, reducing labor and tunnel costs. Furthermore, the tiny particles do not affect the device's normal drainage or the municipal pipe network's filtration system, minimizing the possibility of large gravel accumulation causing drainage problems and disrupting the tunnel's drainage.

The first rigid pipe 403 is welded to the fourth U-shaped plate 401. A corrugated pipe 404 is installed between the first rigid pipe 403 and the elbow 405. The corrugated pipe 404 and the elbow 405 are assembled together using a nut and screw assembly 406. A first horn cover 407 is welded to the surface of the elbow 405, and a first inlet pipe 408 is welded to the end of the elbow 405. The vertical cylindrical base 410 is welded to the fifth U-shaped plate 409. At the top, a vertical cylinder 411 is welded between the fourth U-shaped plate 401 and the vertical cylinder base 410.

[0041] After the water is treated by crushed stone, it flows into the fourth U-shaped plate 401. Under normal weather conditions, the water flow into the device is small and the impact force is insufficient. The water volume in the fourth U-shaped plate 401 is small and the weight of the water is light. At this time, because the force of the second spring 414 is strong, its upward force is strong. The impact force of the water flow and gravity will not cause the pressure plate 413 to drop. The corrugated pipe 404 can be lengthened according to actual needs. The elbow 405 can be installed on the upper surface of the municipal pipe network. A round hole will be opened on the upper surface of the municipal pipe network first. Then, the first inlet pipe 408 will be inserted into the round hole. Then, the first horn cover 407 will be placed on the round hole on the upper surface of the municipal pipe network. Finally, waterproof and high-strength concrete will be used to seal the edge. Water flows into the municipal pipe network through the fourth U-shaped plate 401, the first rigid pipe 403, the corrugated pipe 404, the elbow 405, and the first access pipe 408. Under extreme weather conditions, the amount of water entering the pipe module 4 increases dramatically. At this time, the water flow is turbulent and the water impact force is strong. The water in the fourth U-shaped plate 401 surges, and the weight of the water increases. At this time, the impact force and weight of the water exceed the force of the second spring 414. At this time, the impact pressure plate 413 will be pressed down. The vertical cylinder 411 is used to regulate the downward path of the impact pressure plate 413. After the impact pressure plate 413 is pressed down, the water in the fourth U-shaped plate 401 will be diverted to the fifth U-shaped plate 409. The water entering the fifth U-shaped plate 409 enters the municipal pipe network through the fifth U-shaped plate 409, the second rigid pipe 415, and the second access pipe 417. The second access pipe 417 needs to be directly connected to the municipal pipe network. The second horn cover 416 needs to be covered at the end of the municipal pipe network, and then the edges are sealed with waterproof and high-strength concrete.

[0042] By setting up pipeline module 4, after the device is installed in the tunnel, it can automatically distribute the water flow according to the amount of water entering the device after extreme weather occurs. This allows the water in the tunnel to be discharged smoothly, which reduces the probability of vehicles being unable to pass through the tunnel normally due to the pipeline flow not matching the water flow under extreme weather conditions. This also reduces the pressure on traffic and municipal command to some extent.

[0043] A construction method for a tunnel drainage device includes the following steps: Step 1: Water in the tunnel flows into the gravel disposal module 3 through the first rain grate 2. The gravel flowing in with the water is crushed in the gravel disposal module 3. The crushed gravel will be smaller in volume. The smaller gravel will follow the water flow into the pipe module 4 and be discharged into the municipal pipe network from the pipe module 4. In extreme weather conditions, when the flow rate is large, the gravel will be diverted through the pipe module 4 after being processed in the gravel disposal module 3, reducing the probability of backflow caused by the inability of a single-diameter pipe to handle a large flow of water. Step 2: The first opening plate 305 is opened by the top mushroom head 317, allowing water to enter the porous cylinder 316, thereby adding water to the water-filling counterweight box 315 and increasing its weight. After the water-filling counterweight box 315 is increased in weight, it pulls the wire rope 311 to move on the first fixed pulley 308 or the second fixed pulley 310, which in turn lifts the lower pressure box 321. The second opening plate 320 is opened by the short column 329, allowing water to flow out of the water-filling counterweight box 315 and reducing its weight. This causes the lower pressure box 321 to fall, water to be filled into the water-filling counterweight box 315, and the lower pressure plate 324 to press down, thereby causing the crushed stone pressure plate 326 to crush the crushed stone. The processed crushed stone enters the second drain trough through the isolation net 333 and is discharged. Step 3: Under normal weather conditions, the treated gravel follows the water flow into the fourth U-shaped plate 401. Because the water flow is not large, it directly enters the external municipal pipe network through the first rigid pipe 403, corrugated pipe 404, elbow 405, and first inlet pipe 408. Under extreme weather conditions, the gravel in the turbulent water flow will also be treated. The turbulent water flow has a large impact force, and the fourth U-shaped plate 401 also contains a lot of water. Under the pressure of the impact force and weight, the impact pressure plate 413 moves vertically on the vertical cylinder 411 through the vertical cylinder adapter 412, so that the water can be diverted. This eliminates the need to worry about the pipe being "unable to drain" or "unable to drain". The second spring 414 ensures the support force of the impact pressure plate 413 under normal conditions.

[0044] The working principle of the technical solution provided by this invention is as follows: Water in the tunnel flows into the gravel disposal module 3 through the first grate 2. The gravel flowing in with the water is crushed in the gravel disposal module 3, resulting in smaller gravel volume. The smaller gravel then flows into the pipe module 4 with the water flow and is discharged into the municipal pipe network from the pipe module 4. In extreme weather conditions with large flow rates, the gravel is diverted through the pipe module 4 after being processed in the gravel disposal module 3, reducing the probability of backflow caused by the inability of a single-diameter pipe to handle large flow rates. The extruded polystyrene board 6 minimizes the erosion of the side panel 5 by water from the concrete. Water in the tunnel first enters the gravel disposal module 3 through the first grate 2, and a portion of the water first enters the second grate on the first U-shaped plate 301. Inside 302, another portion of the water is diverted through the triangular diverter 303 to the first U-shaped plate 301. The diverted water, after the mushroom-shaped head 317 pushes open the first opening plate 305, enters the porous cylinder 316 and then the water-filling counterweight box 315, adding weight to it. As the weight increases, the water-filling counterweight box 315 presses down. This pressure causes the wire rope 311 and either the first fixed pulley 308 or the second fixed pulley 310 to move, lifting components such as the pressure box 321. When the water-filling counterweight box 315 falls onto the square groove on the second U-shaped plate 327, the short column 329 pushes open the second opening plate 320, allowing water in the water-filling counterweight box 315 to flow out from the square groove. The water drain hole on the trough falls into the third U-shaped plate 330. When the weight of the water-filling counterweight box 315 disappears, the pressure box 321 will fall directly into the water in the third U-shaped plate 330. Water enters the pressure box 321 through the water inlet. As the water in the pressure box 321 gradually increases, the weight above the pressure plate 324 increases, and the pressure plate 324 presses down, thereby driving the crushed stone pressure plate 326 to crush the crushed stone in the third U-shaped plate 330. When the water-filling counterweight box 315 is refilled with water, it will pull the pressure box 321 up again, and the water in the pressure box 321 will drain out through the water outlet, thus restoring the pressure plate 324 to its original state. The inclined plate 331 of the third U-shaped plate 330 is responsible for causing the crushed stone flowing into the water in the third U-shaped plate 330 to roll into the third U-shaped plate. At a horizontal level of 330, the isolation net 333 is responsible for isolating larger gravel particles, which are then crushed again. Smaller gravel particles pass through the isolation net 333 along with the water flow and are then flushed into the pipe module 4 from the second drain. From there, they enter the municipal pipe network. After being processed by the gravel, the water flows into the fourth U-shaped plate 401. Under normal weather conditions, the water flow into this device is small, resulting in insufficient impact force. The water volume in the fourth U-shaped plate 401 is small, and its weight is relatively light. Because the second spring 414 has a strong force, its upward pushing force is strong. The normal water flow impact force and gravity will not cause the pressure plate 413 to descend. The corrugated pipe 404 can be lengthened according to actual needs, and the elbow 405 can be installed on the upper surface of the municipal pipe network.A circular hole is first drilled on the surface of the municipal pipeline network. Then, the first inlet pipe 408 is inserted into the circular hole, followed by the first horn cover 407 covering the circular hole on the surface of the municipal pipeline network. Finally, waterproof and high-strength concrete is used to seal the edges. Water flows into the municipal pipeline network through the fourth U-shaped plate 401, the first rigid pipe 403, the corrugated pipe 404, the elbow 405, and the first inlet pipe 408. Under extreme weather conditions, the amount of water entering the pipe module 4 increases dramatically. At this time, the water flow is rapid and the water impact force is strong. The water in the fourth U-shaped plate 401 surges, and the weight of the water increases. At this time, the impact force and weight of the water exceed those of the second U-shaped plate 401. The force of spring 414 causes the impact pressure plate 413 to be pressed down. The vertical cylinder 411 regulates the downward path of the impact pressure plate 413. After the impact pressure plate 413 is pressed down, the water in the fourth U-shaped plate 401 is diverted to the fifth U-shaped plate 409. The water entering the fifth U-shaped plate 409 passes through the fifth U-shaped plate 409, the second rigid pipe 415, and the second inlet pipe 417 into the municipal pipe network. The second inlet pipe 417 needs to be directly connected to the municipal pipe network. The second horn cover 416 needs to be placed over the end of the municipal pipe network, and then sealed with waterproof and high-strength concrete.

10. The construction method of the tunnel drainage device according to claims 1-9, characterized in that, Includes the following steps: Step 1: Water in the tunnel flows into the gravel disposal module through the first rain grate. The gravel flowing in with the water is crushed in the gravel disposal module. The crushed gravel will be smaller in volume. The smaller gravel will follow the water flow into the pipe module and then be discharged into the municipal pipe network. In extreme weather conditions, when the flow rate is large, the gravel will be diverted through the pipe module after being processed in the gravel disposal module, reducing the probability of backflow caused by the inability of a single-diameter pipe to handle a large flow of water. Step 2: The first opening plate is opened by the mushroom-shaped top, allowing water to enter the porous cylinder, thus adding water to the water-filled counterweight box and increasing its weight. After the water-filled counterweight box is increased in weight, it pulls the steel wire rope to move on the first or second fixed pulley, which in turn lifts the lower pressure box. The short column opens the second opening plate, allowing water to flow out of the water-filled counterweight box, reducing its weight and causing the lower pressure box to fall. Water is then added to the water-filled counterweight box, and the lower pressure plate presses down, causing the crushed stone plate to crush the crushed stone. The processed crushed stone is discharged into the second drain through the isolation net. Step 3: Under normal weather conditions, the treated gravel follows the water flow into the fourth U-shaped plate. Because the water flow is not large, it directly enters the external municipal pipe network through the first rigid pipe, corrugated pipe, elbow, and first inlet pipe. In extreme weather conditions, the gravel in the turbulent water flow will also be treated. The turbulent water flow has a large impact force, and the fourth U-shaped plate also contains a lot of water. Under the pressure of the impact force and weight, the impact pressure plate moves vertically on the vertical cylinder through the vertical cylinder adapter, so that the water can be diverted. This eliminates the need to worry about the pipe being "unable to drain" or "unable to drain". The second spring ensures the support force of the impact pressure plate under normal conditions.
