Description

Technical Field

[0001] This invention relates to the field of subway tunnels, and more specifically, to a reinforcement structure and construction method for a water-crossing section of a subway tunnel. Background Technology

[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. Trains run on fully enclosed tracks. Lines in urban centers are primarily located underground tunnels, while lines outside urban centers are generally located on elevated bridges or at ground level. Subways are high-density, high-capacity urban rail transit systems encompassing various underground and above-ground road rights in urban areas. Since subways spend most of their time in tunnels, they sometimes pass through water-filled tunnels. To ensure the safety of subway operation, tunnel reinforcement structures are required. Existing tunnel reinforcement components lack stability during use, easily causing the devices to sway, resulting in insufficient reinforcement of the tunnel sidewalls and roof, causing inconvenience to users. Summary of the Invention

[0003] This invention provides a reinforcement structure and construction method for water-crossing sections of subway tunnels, aiming to solve the problem that existing tunnel reinforcement components are not stable enough during use, which can easily cause the device to shake during use, resulting in insufficient reinforcement of the tunnel sidewalls and roof, and causing inconvenience to users.

[0004] The present invention is implemented as follows: a reinforcement structure for a water-crossing section of a subway tunnel, comprising a bottom net and a reinforcement mechanism installed above the bottom net, wherein the reinforcement mechanism comprises a fixing component and a supporting component;

[0005] The fixing assembly includes a central mesh, vertical ribs, surrounding ribs, a central filling opening, a fixing plate, a fixing column, a cement slab, fixing ribs, and a pressure plate. The central mesh is installed above the bottom mesh, and vertical ribs are installed inside the central mesh. Surrounding ribs are installed above the central mesh, and a central filling opening is provided above the surrounding ribs. A fixing plate is installed inside the central filling opening, and a fixing column is installed inside the fixing plate. A cement slab is installed on the rear side of the fixing plate, and fixing ribs are installed above the cement slab. A pressure plate is installed above the fixing ribs.

[0006] The support assembly includes side filling ports, side cement plates, fixing pads, fastening bolts, bottom gaskets, long support columns, connecting columns, and short support columns. The fixing columns have side filling ports on both the left and right sides, and side cement plates are installed inside the side filling ports. The fixing pads are installed inside the side cement plates, and fastening bolts are installed on the sides of the fixing pads. Bottom gaskets are installed at the bottom of the fixing pads, and long support columns are installed above the fixing pads. Connecting columns are installed at the rear of the long support columns, and short support columns are fixed at the bottom of the connecting columns.

[0007] Preferably, a track is installed above the pressure plate, a top plate is installed outside the central filling port, side plates are installed on the left and right sides of the top plate, and an installation groove is opened in front of the side plate. A connecting piece is installed inside the installation groove, a filling rib is installed behind the side plate, an arc plate is installed above the side plate, and an inner plate is fixed inside the side plate.

[0008] Preferably, the bottom mesh and the middle mesh are parallel to each other, and the middle mesh, the bottom mesh, and the vertical ribs are welded together. The vertical ribs are evenly distributed inside the bottom mesh. The fixing plate and the top plate are connected by grouting. The fixing columns are evenly distributed inside the fixing plate. The fixing plates are symmetrical about the center line of the top plate.

[0009] Preferably, the track forms a detachable structure with the cement slab through the cooperation between the pressure plate and the fixing rib, and the dimensions between the track and the fixing plate match each other, and the vertical rib and the fixing plate are connected by pouring.

[0010] Preferably, the long support column forms a detachable structure with the side filling port through the cooperation between the fastening bolt and the fixing pad, and the distance between the side cement plate and the bottom pad is equal to the thickness of the side filling port. Furthermore, the connecting column is welded to both the long support column and the short support column, and the long support columns are symmetrical about the center line of the top plate.

[0011] Preferably, the filling reinforcement includes horizontal reinforcement, side reinforcement and longitudinal reinforcement. The horizontal reinforcement is vertically mounted with side reinforcement, and longitudinal reinforcement is mounted on the upper and lower sides of the horizontal reinforcement. The horizontal reinforcement and side reinforcement are welded together, and the horizontal reinforcement and longitudinal reinforcement are perpendicular to each other. The top of the longitudinal reinforcement has an arc-shaped structure.

[0012] Preferably, the lifting mechanism includes a left protective plate, a sliding groove, a motor, a threaded rod, a lifting plate, a slot, a sliding shaft, a connecting plate, a lifting rod, a stabilizing slider, a fixed gear, a top groove, a rack, a bottom rotating shaft, and a stabilizing rod. The surface of the left protective plate has a sliding groove, and a motor is installed on the right side of the left protective plate. A threaded rod is installed at the bottom of the motor, and a lifting plate is engaged with the bottom of the threaded rod. Slots are formed on both sides of the lifting plate, and a sliding shaft is installed inside the slots. A connecting plate is installed on the other side of the sliding shaft, and a lifting rod is fixed to the end of the connecting plate. A stabilizing slider is installed inside the lifting rod, and a fixed gear is installed at the top of the lifting rod. A top groove is formed at the top of the left protective plate, and a rack is installed inside the top groove. A bottom rotating shaft is installed at the bottom of the lifting rod, and a stabilizing rod is installed on the right side of the bottom rotating shaft.

[0013] Preferably, the sliding shaft forms a lifting structure with the left protective plate via the threaded rod, and the connecting plate forms a rotating structure with the lifting plate via the cooperation between the sliding shaft and the slot, and the lifting rod forms a swing structure with the connecting plate and the lifting plate. This allows the motor to drive the threaded rod to move up and down inside the device. During the lifting and lowering process, the connecting plate swings up and down inside the slot via the sliding shaft. The connecting plate and the lifting rod are fixed to each other. Therefore, when the connecting plate swings, it drives the lifting rod to rotate inside the device, allowing the lifting rod to move up and down at its apex inside the device, thus lifting the top plate. This makes it easy to fix the top plate in water-crossing sections and prevents the top plate from getting wet and affecting its use.

[0014] Preferably, the lifting rod forms a rotating structure with the left protective plate via a bottom pivot, and the lifting rod meshes with a fixed gear and a rack, while the stabilizing slider forms a sliding structure with the left protective plate via a groove. This allows the lifting rod to rise and fall within the device as it rotates inside. The meshing of the fixed gear and rack at the top of the lifting rod improves the stability between the lifting rod and the top groove. Furthermore, the stabilizing slider slides within the rear groove when the lifting rod swings, further enhancing the device's stability. This facilitates the lifting rod lifting the top plate via the rack, preventing the top plate from getting wet and affecting the device's operation.

[0015] This invention provides a reinforcement structure and construction method for a water-crossing section of a subway tunnel, the method comprising the following steps:

[0016] S1. First, the user's bottom and middle nets support the vertical reinforcement bars, facilitating the filling of cement inside the bottom and middle nets and the vertical reinforcement bars. Then, the bottom, middle, and vertical reinforcement bars are buried underground to support the device. At the same time, the bottom and vertical reinforcement bars are also fixed at the water-crossing locations using cement filling, facilitating the reinforcement of water-crossing sections. Additionally, two sets of bottom and middle nets are installed at the bottom of the top plate to further improve the stability of the device and facilitate its reinforcement. Then, the fixing plate is fixed inside the top plate by cement pouring. At the same time, the fixing columns installed inside the fixing plate are also poured together with the fixing plate by cement pouring, which improves the stability of the device. The installation of different fixing columns inside the fixing plate further improves the stability of the device when installed in water-crossing sections, facilitating the reinforcement of tunnels in water-crossing sections. Afterward, the track is fixed above the device by pressure plates, thereby improving the stability of the track inside the tunnel and facilitating the use of the device. In addition, multiple fixing plates are installed at the bottom of the track to further improve the stability of the track and facilitate the reinforcement of the subway tunnel.

[0017] S2. Next, the mounting groove on the front side of the side plate facilitates the connection of the side plate in the front and back directions. At the same time, the top of the side plate is connected to the arc plate through the connecting piece. The arc plate has an arc structure and also supports the top of the tunnel. It not only reinforces the water-crossing part, but also reinforces the top of the tunnel, improving the stability of the device. After installation, the long support column supports the side plate. The long support column is fixed to the inside of the side cement plate by the bottom fastener and bottom gasket, which facilitates the use of the device. First, the long support column is installed inside the side filling port, and then the long support column is fixed by cement pouring. Then, the bottom gasket is fixed to the bottom of the long support column, which facilitates the long support column to support the device and improves the stability of the device, thereby improving the stability of the side. Finally, the horizontal bar is welded together with the side bar and the longitudinal bar, and then cement is filled into the inside of the filling bar between the side plates to fix the horizontal bar, side bar and longitudinal bar together, improving the stability of the device. At the same time, the cross-fixing method of the horizontal bar, side bar and longitudinal bar further improves the stability of the device, thereby reinforcing the entire tunnel.

[0018] S3. Finally, during use, the motor drives the threaded rod to rise and fall inside the device. During this rising and falling, the connecting plate swings and rises and falls inside the slot via the sliding shaft. The connecting plate and the lifting rod are fixed to each other. Therefore, when the connecting plate swings, it drives the lifting rod to rotate inside the device, causing the top of the lifting rod to rise and fall, thus lifting the top plate. This makes it easy to fix the top plate in water-prone sections, preventing the top plate from getting wet and affecting its use. When the lifting rod rotates inside the device, the top of the lifting rod rises and falls inside the device. Since the fixed gear and rack installed at the top of the lifting rod mesh with each other, the stability between the lifting rod and the top slot is improved. At the same time, when the lifting rod swings, the stabilizing slider slides inside the rear slot, further improving the stability of the device. This makes it easy for the lifting rod to lift the top plate via the rack, preventing the top plate from getting wet and affecting the use of the device.

[0019] The present invention provides a reinforcement structure and construction method for water-crossing sections of subway tunnels, which has the following beneficial effects when used:

[0020] 1. The present invention provides a reinforcement structure and construction method for a water-crossing section of a subway tunnel. In use, the installation of a bottom mesh, a middle mesh, and vertical bars allows the bottom mesh and middle mesh to support the vertical bars, facilitating the filling of cement inside the bottom mesh and vertical bars. The bottom mesh, middle mesh, and vertical bars are then buried underground to support the device. At the same time, the cement filling of the bottom mesh and vertical bars can also fix them at the water-crossing location, facilitating the reinforcement of the water-crossing section. In addition, the installation of two sets of bottom mesh and middle mesh at the bottom of the top plate can further improve the stability of the device and facilitate the reinforcement of the device.

[0021] 2. The present invention provides a reinforcement structure and construction method for a water-crossing section of a subway tunnel. In use, the fixing plate is poured into the inside of the top plate, so that the fixing plate can be fixed inside the top plate by pouring cement. At the same time, the fixing column installed inside the fixing plate can also be poured together with the fixing plate by cement, which can improve the stability of the device. The installation of different fixing columns inside the fixing plate can further improve the stability of the device when installed in the water-crossing section, making it convenient for the device to reinforce the tunnel in the water-crossing section.

[0022] 3. The present invention provides a reinforcement structure and construction method for a water-crossing section of a subway tunnel. In use, the horizontal and side bars are welded together, so that the horizontal bars are welded together with the longitudinal bars through the side bars. Then, cement is used to fill the interior of the filler bars between the side plates to fix the horizontal, side, and longitudinal bars together, which can improve the stability of the device. At the same time, the cross-fixing method of the horizontal, side, and longitudinal bars can further improve the stability of the device, thereby strengthening the entire tunnel.

[0023] 4. This invention provides a reinforcement structure and construction method for water-prone sections of subway tunnels. A motor drives a threaded rod to rise and fall within the device. During this rising and falling, a connecting plate swings and rises within the slot via a sliding shaft. The connecting plate and the lifting rod are fixed together. Therefore, when the connecting plate swings, it drives the lifting rod to rotate within the device, allowing the lifting rod to rise and fall at its apex, thus lifting the top plate. This facilitates fixing the top plate in water-prone sections, preventing water from affecting its use. Furthermore, as the lifting rod rotates within the device, its apex rises and falls within the device. Because the fixed gear and rack installed at the top of the lifting rod mesh with each other, the stability between the lifting rod and the top slot is improved. Simultaneously, when the lifting rod swings, a stabilizing slider slides within the rear slot, further enhancing the device's stability. This allows the lifting rod to lift the top plate via the rack, preventing water from affecting the device's use. Attached Figure Description

[0036] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] For examples, please refer to Figure 1-7 .

[0038] This embodiment provides a reinforcement structure for a water-crossing section of a subway tunnel, including a bottom net 1 and a reinforcement mechanism installed on top of the bottom net 1. The reinforcement mechanism includes a fixing component and a supporting component.

[0039] The fixing components include a central mesh 2, vertical ribs 3, surrounding ribs 4, a central filling opening 5, a fixing plate 6, a fixing column 7, a cement board body 8, fixing ribs 9, and a pressure plate 10. The central mesh 2 is installed above the bottom mesh 1, and vertical ribs 3 are installed inside the central mesh 2. The surrounding ribs 4 are installed above the central mesh 2, and a central filling opening 5 is opened above the surrounding ribs 4. The fixing plate 6 is installed inside the central filling opening 5, and a fixing column 7 is installed inside the fixing plate 6. The cement board body 8 is installed on the rear side of the fixing plate 6, and fixing ribs 9 are installed above the cement board body 8. The pressure plate 10 is installed above the fixing ribs 9.

[0040] The support assembly includes a side filling port 13, a side cement plate 14, a fixing pad 15, a fastening bolt 16, a bottom gasket 17, a long support column 18, a connecting column 19, and a short support column 20. The fixing column 7 has side filling ports 13 on both the left and right sides, and the side cement plate 14 is installed inside the side filling port 13. The fixing pad 15 is installed inside the side cement plate 14, and the fastening bolt 16 is installed on the side of the fixing pad 15. The bottom gasket 17 is installed at the bottom of the fixing pad 15, and the long support column 18 is installed above the fixing pad 15. The connecting column 19 is installed on the rear side of the long support column 18, and the short support column 20 is fixed at the bottom of the connecting column 19.

[0041] A track 11 is installed above the pressure plate 10. A top plate 12 is installed outside the central filling port 5. Side plates 21 are installed on the left and right sides of the top plate 12. An installation groove 22 is opened in front of the side plate 21. A connecting piece 23 is installed inside the installation groove 22. A filling rib 24 is installed behind the side plate 21. An arc plate 25 is installed above the side plate 21. An inner plate 26 is fixed inside the side plate 21.

[0042] The bottom mesh 1 and the middle mesh 2 are parallel to each other, and the middle mesh 2 is welded to the bottom mesh 1 and the vertical ribs 3. The vertical ribs 3 are evenly distributed inside the bottom mesh 1, so that the bottom mesh 1 and the middle mesh 2 can support the vertical ribs 3. It is convenient to fill the inside of the bottom mesh 1 and the vertical ribs 3 with cement, and then bury the bottom mesh 1, the middle mesh 2 and the vertical ribs 3 underground to support the device. At the same time, the bottom mesh 1 and the vertical ribs 3 can also be fixed at the water-crossing position by filling with cement, which is convenient for reinforcing the water-crossing section. At the same time, the installation of two sets of bottom mesh 1 and middle mesh 2 at the bottom of the top plate 12 can further improve the stability of the device and facilitate the installation of cement. The device is reinforced by a concrete pouring connection between the fixing plate 6 and the top plate 12. The fixing columns 7 are evenly distributed inside the fixing plate 6, and the fixing plates 6 are symmetrical about the center line of the top plate 12. This allows the fixing plate 6 to be fixed inside the top plate 12 by concrete pouring. At the same time, the fixing columns 7 installed inside the fixing plate 6 can also be poured together with the fixing plate 6 by concrete pouring, which can improve the stability of the device. The installation of different fixing columns 7 inside the fixing plate 6 can further improve the stability of the device when installed in water-crossing sections, making it convenient for the device to reinforce tunnels in water-crossing sections.

[0043] The track 11 forms a detachable structure with the cement slab 8 through the cooperation between the pressure plate 10 and the fixing rib 9. The dimensions between the track 11 and the fixing plate 6 are mutually matched, and the vertical rib 3 and the fixing plate 6 are connected by a grouting process. This allows the track 11 to be fixed above the device through the pressure plate 10, thereby improving the stability of the track 11 inside the tunnel and facilitating the use of the device. Furthermore, the multiple fixing plates 6 installed at the bottom of the track 11 can further improve the stability of the track 11 and facilitate the device to reinforce the inside of the subway tunnel.

[0044] The long support column 18 forms a detachable structure with the side filling port 13 through the cooperation between the fastening bolt 16 and the fixing pad 15. The distance between the side cement plate 14 and the bottom pad 17 is equal to the thickness of the side filling port 13. The connecting column 19 is welded to both the long support column 18 and the short support column 20. The long support columns 18 are symmetrical about the center line of the top plate 12, so that the long support column 18 can be fixed inside the side cement plate 14 by the fastening bolt 16 and the bottom pad 17. This facilitates the use of the device. First, the long support column 18 is installed inside the side filling port 13. Then, the long support column 18 is fixed by pouring cement. After that, the bottom pad 17 is fixed to the bottom of the long support column 18, which facilitates the long support column 18 to support the device and improves the stability of the device, thereby improving the stability of the side.

[0045] The filling reinforcement 24 includes horizontal reinforcement 2401, side reinforcement 2402, and longitudinal reinforcement 2403. The horizontal reinforcement 2401 is vertically connected to the side reinforcement 2402, and the longitudinal reinforcement 2403 is installed on the upper and lower sides of the horizontal reinforcement 2401. The horizontal reinforcement 2401 and the side reinforcement 2402 are welded together, and the horizontal reinforcement 2401 and the longitudinal reinforcement 2403 are perpendicular to each other. The top of the longitudinal reinforcement 2403 has an arc-shaped structure, so that the horizontal reinforcement 2401 is welded together with the side reinforcement 2402 and the longitudinal reinforcement 2403. Then, cement is used to fill the interior of the filling reinforcement 24 between the side plates 21, fixing the horizontal reinforcement 2401, side reinforcement 2402, and longitudinal reinforcement 2403 together, which can improve the stability of the device. At the same time, the cross-fixing method of the horizontal reinforcement 2401, side reinforcement 2402, and longitudinal reinforcement 2403 can further improve the stability of the device, thereby strengthening the entire tunnel.

[0046] The lifting mechanism 27 includes a left protective plate 2701, a slide groove 2702, a motor 2703, a threaded rod 2704, a lifting plate 2705, a slot 2706, a sliding shaft 2707, a connecting plate 2708, a lifting rod 2709, a stabilizing slider 2710, a fixed gear 2711, a top slot 2712, a rack 2713, a bottom rotating shaft 2714, and a stabilizing rod 2715. The surface of the left protective plate 2701 has a slide groove 2702, and the motor 2703 is installed on the right side of the left protective plate 2701. A threaded rod 2704 is installed at the bottom of the motor 2703, and the lifting plate 2705 is engaged with the bottom of the threaded rod 2704. The lowering plate 2705 has slots 2706 on both sides, and a sliding shaft 2707 is installed inside the slots 2706. A connecting plate 2708 is installed on the other side of the sliding shaft 2707, and a lifting rod 2709 is fixed to the end of the connecting plate 2708. A stabilizing slider 2710 is installed inside the lifting rod 2709, and a fixed gear 2711 is installed on the top of the lifting rod 2709. The top of the left protective plate 2701 has a top groove 2712, and a rack 2713 is installed inside the top groove 2712. A bottom rotating shaft 2714 is installed at the bottom of the lifting rod 2709, and a stabilizing rod 2715 is installed on the right side of the bottom rotating shaft 2714.

[0047] The sliding shaft 2707 forms a lifting structure with the left protective plate 2701 through the threaded rod 2704, and the connecting plate 2708 forms a rotating structure with the lifting plate 2705 through the cooperation between the sliding shaft 2707 and the slot 2706. The lifting rod 2709 forms a swinging structure with the connecting plate 2708 and the lifting plate 2705, so that the motor 2703 can drive the threaded rod 2704 to move up and down inside the device. During the lifting, the connecting plate 2708 will swing up and down inside the slot 2706 through the sliding shaft 2707. The connecting plate 2708 and the lifting rod 2709 are fixed to each other. Therefore, when the connecting plate 2708 swings, it will drive the lifting rod 2709 to rotate inside the device, so that the lifting rod 2709 can move up and down to the top point inside the device, which can lift the top plate 12, making it easy to fix the top plate 12 in water-crossing sections and prevent the top plate 12 from being affected by water.

[0048] The lifting rod 2709 forms a rotating structure with the left protective plate 2701 via the bottom pivot 2714. The lifting rod 2709 meshes with the rack 2713 via the fixed gear 2711, and the stabilizing slider 2710 forms a sliding structure with the left protective plate 2701 via the slide groove 2702. This allows the top of the lifting rod 2709 to rise and fall within the device as it rotates inside. The meshing of the fixed gear 2711 and rack 2713 on the top of the lifting rod 2709 improves the stability between the lifting rod 2709 and the top groove 2712. Furthermore, when the lifting rod 2709 swings, the stabilizing slider 2710 slides within the rear slide groove 2702, further enhancing the stability of the device. This facilitates the lifting rod 2709 lifting the top plate 12 via the rack 2713, preventing the top plate 12 from getting wet and affecting the device's operation.

[0049] This solution also provides a reinforcement structure and construction method for water-crossing sections of subway tunnels, the method including the following steps:

[0050] S1. First, the user uses the bottom mesh 1 and middle mesh 2 to support the vertical reinforcement 3, facilitating the filling of cement inside the bottom mesh 1 and vertical reinforcement 3. Then, the bottom mesh 1, middle mesh 2, and vertical reinforcement 3 are buried underground to support the device. At the same time, the bottom mesh 1 and vertical reinforcement 3 are also fixed at the water-crossing location using cement filling, facilitating the reinforcement of the water-crossing section. Additionally, two sets of bottom mesh 1 and middle mesh 2 are installed at the bottom of the top plate 12 to further improve the stability of the device and facilitate reinforcement. Then, the fixing plate 6 is fixed inside the top plate 12 by cement pouring. The internally installed fixing columns 7 are also poured together with the fixing plates 6 with cement, which improves the stability of the device. The different fixing columns 7 installed inside the fixing plates 6 further improve the stability of the device when installed in water-crossing sections, making it easier for the device to reinforce tunnels in water-crossing sections. Then, the track 11 is fixed above the device by the pressure plate 10, thereby improving the stability of the track 11 inside the tunnel and facilitating the use of the device. In addition, multiple fixing plates 6 are installed at the bottom of the track 11, which further improves the stability of the track 11 and facilitates the device to reinforce the inside of the subway tunnel.

[0051] S2. Next, the mounting groove 22 on the front side of the side plate 21 facilitates the connection of the side plate 21 in the front and rear directions. At the same time, the top of the side plate 21 is connected to the arc plate 25 through the connecting piece 23. The arc plate 25 has an arc-shaped structure and also supports the top of the tunnel, which not only reinforces the water-crossing interior but also the tunnel top, improving the stability of the device. After installation, the long support column 18 supports the side plate 21. The long support column 18 is fixed to the inside of the side cement plate 14 by the bottom fastening bolt 16 and the bottom gasket 17, which facilitates the use of the device. First, the long support column 18 is installed inside the side filling port 13, and then the cement is poured in. The long support column 18 is fixed in one step, and then the bottom pad 17 is fixed to the bottom of the long support column 18 to facilitate the support of the device by the long support column 18, thereby improving the stability of the device and thus improving the stability of the side. Finally, the horizontal reinforcement 2401 is welded together with the side reinforcement 2402 and the longitudinal reinforcement 2403, and then cement is used to fill the inside of the filling reinforcement 24 between the side plates 21 to fix the horizontal reinforcement 2401, the side reinforcement 2402 and the longitudinal reinforcement 2403 together, thereby improving the stability of the device. At the same time, the cross-fixing of the horizontal reinforcement 2401, the side reinforcement 2402 and the longitudinal reinforcement 2403 further improves the stability of the device, thereby reinforcing the entire tunnel.

[0052] S3. Finally, during use, the motor 2703 drives the threaded rod 2704 to rise and fall inside the device. During this rising and falling, the connecting plate 2708 swings and rises and falls inside the slot 2706 via the sliding shaft 2707. The connecting plate 2708 and the lifting rod 2709 are fixed to each other. Therefore, when the connecting plate 2708 swings, it drives the lifting rod 2709 to rotate inside the device, causing the lifting rod 2709 to rise and fall at its apex inside the device, thus lifting the top plate 12. This makes it easier to fix the top plate 12 in water-crossing sections and prevent the top plate 12 from getting wet. When the lifting rod 2709 rotates inside the device, its apex rises and falls within the device. Since the fixed gear 2711 and rack 2713 installed on the top of the lifting rod 2709 mesh with each other, the stability between the lifting rod 2709 and the top groove 2712 is improved. At the same time, when the lifting rod 2709 swings, the stabilizing slider 2710 slides inside the rear groove 2702, which further improves the stability of the device. This makes it easier for the lifting rod 2709 to lift the top plate 12 through the rack 2713, preventing the top plate 12 from getting wet and affecting the use of the device.

[0053] The working principle is as follows: First, the user's bottom mesh 1 and middle mesh 2 support the vertical ribs 3, facilitating the filling of cement inside the bottom mesh 1 and vertical ribs 3. Then, the bottom mesh 1, middle mesh 2, and vertical ribs 3 are buried underground to support the device. Simultaneously, the bottom mesh 1 and vertical ribs 3 are also fixed at water-contaminated locations using cement filling, facilitating the reinforcement of water-contaminated sections. Furthermore, two sets of bottom mesh 1 and middle mesh 2 are installed at the bottom of the top plate 12 to further improve the stability of the device and facilitate reinforcement. Then, the fixing plate 6 is fixed inside the top plate 12 by cement pouring. The internal fixing column 7 of the 6 is also poured together with the fixing plate 6 with cement, which improves the stability of the device. The different fixing columns 7 installed inside the fixing plate 6 further improve the stability of the device when installed in water-crossing sections, making it easier for the device to reinforce tunnels in water-crossing sections. Then the track 11 is fixed above the device by the pressure plate 10, thereby improving the stability of the track 11 inside the tunnel and facilitating the use of the device. In addition, multiple fixing plates 6 are installed at the bottom of the track 11, which further improves the stability of the track 11 and facilitates the device to reinforce the inside of the subway tunnel.

[0054] Then, the mounting groove 22 on the front side of the side plate 21 facilitates the connection of the side plate 21 in the front and rear directions. At the same time, the top of the side plate 21 is connected to the arc plate 25 through the connecting piece 23. The arc plate 25 has an arc-shaped structure and also supports the top of the tunnel, which not only reinforces the water-crossing interior but also the tunnel top, improving the stability of the device. After installation, the long support column 18 supports the side plate 21. The long support column 18 is fixed to the inside of the side cement plate 14 by the bottom fastening bolt 16 and the bottom gasket 17, which facilitates the use of the device. First, the long support column 18 is installed inside the side filling port 13, and then the long support column 18 is installed by pouring cement. After the support column 18 is fixed, the bottom pad 17 is fixed to the bottom of the long support column 18 to facilitate the support of the device by the long support column 18, thereby improving the stability of the device and thus improving the stability of the side. Finally, the horizontal reinforcement 2401 is welded together with the side reinforcement 2402 and the longitudinal reinforcement 2403. Then, cement is used to fill the inside of the filling reinforcement 24 between the side plates 21 to fix the horizontal reinforcement 2401, the side reinforcement 2402 and the longitudinal reinforcement 2403 together, thereby improving the stability of the device. At the same time, the cross-fixing of the horizontal reinforcement 2401, the side reinforcement 2402 and the longitudinal reinforcement 2403 further improves the stability of the device, thereby reinforcing the entire tunnel.

During the lifting, the connecting plate swings up and down inside the slot via the sliding shaft. The connecting plate and the lifting rod are fixed to each other. Therefore, when the connecting plate swings, it will drive the lifting rod to rotate inside the device, so that the lifting rod can move up and down to the top point inside the device, thus lifting the top plate. This makes it easy to fix the top plate in water-crossing sections and prevent the top plate from getting wet and affecting its use.

The lifting rod also has a fixed gear meshing with a rack, and a stabilizing slider forms a sliding structure with the left protective plate via a groove. This allows the lifting rod to rise and fall within the device as it rotates inside. The meshing of the fixed gear and rack at the top of the lifting rod improves the stability between the lifting rod and the top groove. Furthermore, the stabilizing slider slides within the rear groove when the lifting rod swings, further enhancing the device's stability. This allows the lifting rod to lift the top plate via the rack, preventing water from affecting the device's operation.

10. A construction method for a water-crossing section of a subway tunnel, using the reinforcement structure described in any one of claims 1-9, characterized in that, Includes the following steps: S1. First, the user's bottom and middle nets support the vertical reinforcement bars, facilitating the filling of cement inside the bottom and middle nets and the vertical reinforcement bars. Then, the bottom, middle, and vertical reinforcement bars are buried underground to support the device. At the same time, the bottom and vertical reinforcement bars are also fixed at the water-crossing locations using cement filling, facilitating the reinforcement of water-crossing sections. Additionally, two sets of bottom and middle nets are installed at the bottom of the top plate to further improve the stability of the device and facilitate its reinforcement. Then, the fixing plate is fixed inside the top plate by cement pouring. At the same time, the fixing columns installed inside the fixing plate are also poured together with the fixing plate by cement pouring, which improves the stability of the device. The installation of different fixing columns inside the fixing plate further improves the stability of the device when installed in water-crossing sections, facilitating the reinforcement of tunnels in water-crossing sections. Afterward, the track is fixed above the device by pressure plates, thereby improving the stability of the track inside the tunnel and facilitating the use of the device. In addition, multiple fixing plates are installed at the bottom of the track to further improve the stability of the track and facilitate the reinforcement of the subway tunnel. S2. Next, the mounting groove on the front side of the side plate facilitates the connection of the side plate in the front and back directions. At the same time, the top of the side plate is connected to the arc plate through the connecting piece. The arc plate has an arc structure and also supports the top of the tunnel. It not only reinforces the water-crossing part, but also reinforces the top of the tunnel, improving the stability of the device. After installation, the long support column supports the side plate. The long support column is fixed to the inside of the side cement plate by the bottom fastener and bottom gasket, which facilitates the use of the device. First, the long support column is installed inside the side filling port, and then the long support column is fixed by cement pouring. Then, the bottom gasket is fixed to the bottom of the long support column, which facilitates the long support column to support the device and improves the stability of the device, thereby improving the stability of the side. Finally, the horizontal bar is welded together with the side bar and the longitudinal bar, and then cement is filled into the inside of the filling bar between the side plates to fix the horizontal bar, side bar and longitudinal bar together, improving the stability of the device. At the same time, the cross-fixing method of the horizontal bar, side bar and longitudinal bar further improves the stability of the device, thereby reinforcing the entire tunnel. S3. Finally, during use, the motor drives the threaded rod to rise and fall inside the device. During this rising and falling, the connecting plate swings and rises and falls inside the slot via the sliding shaft. The connecting plate and the lifting rod are fixed to each other. Therefore, when the connecting plate swings, it drives the lifting rod to rotate inside the device, causing the top of the lifting rod to rise and fall, thus lifting the top plate. This makes it easy to fix the top plate in water-prone sections, preventing the top plate from getting wet and affecting its use. When the lifting rod rotates inside the device, the top of the lifting rod rises and falls inside the device. Since the fixed gear and rack installed at the top of the lifting rod mesh with each other, the stability between the lifting rod and the top slot is improved. At the same time, when the lifting rod swings, the stabilizing slider slides inside the rear slot, further improving the stability of the device. This makes it easy for the lifting rod to lift the top plate via the rack, preventing the top plate from getting wet and affecting the use of the device.
