Description

Technical Field

[0001] This invention relates to the field of building insulation and protection, and more specifically to a seepage-proof and water-proof structure for urban rail construction and its construction method. Background Technology

[0002] With the rapid advancement of urbanization in my country, a large number of people have flocked to cities. Large and medium-sized cities across the country have generally experienced problems such as overcrowding, traffic congestion, energy shortages, and increased environmental pollution. Simple urban roads and bridges are no longer sufficient to meet today's transportation needs. More and more cities in my country are building urban tunnels and underground rail transit to solve traffic congestion problems. Nowadays, the construction technology of urban tunnel drainage systems is receiving increasing attention.

[0003] The tunnel itself has a large amount of seepage. Due to the limited capacity of the drainage ditch, water overflows onto the ground, affecting the normal work of construction workers, reducing construction efficiency, and shortening the tunnel's service life. Existing tunnel waterproofing and seepage prevention structures are too simple, relying solely on drainage ditches for drainage, resulting in poor drainage performance. Furthermore, because the tunnel is in a damp state for a long time and is not exposed to sunlight, the seepage points remain damp and are difficult to treat. Therefore, we propose a seepage-proof and water-proof structure and its construction method for urban rail construction. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a seepage-proof and water-proof structure and its construction method for urban rail construction. This can solve the problem of large seepage in the tunnel body, where the limited capacity of the drainage ditch causes water to overflow onto the ground, affecting the normal work of construction personnel, resulting in low construction efficiency and reduced tunnel service life. Existing tunnel waterproof and seepage-proof structures are too simple, relying solely on drainage ditches for drainage, which has poor drainage effect. Furthermore, because the tunnel is in a damp state for a long time and is not exposed to sunlight, the seepage points remain damp for a long time, making the problem difficult to deal with.

[0014] According to another aspect of the present invention, a method for waterproofing and seepage prevention in urban rail construction is provided, comprising the following steps:

[0015] S1. When using, the water collection layer is attached to the top of the inner side of the tunnel to collect seepage water, and the waterproof layer is attached to the inner side of the water collection layer for waterproofing.

[0016] S2. The water collection and concentration mechanism collects the water and then discharges it into the water collection and drying mechanism through the water collection pipe. The water collection and drying mechanism is used to collect the water collected in multiple water collection tanks opened above the water collection layer, which facilitates the collection of seepage water.

[0017] S3. By adjusting the connection direction of the water inlet concentrator, and then starting the drying function of the water collection and drying mechanism, the water collection tank is dried.

[0018] S4. When the water collection and drying mechanism is used, it blocks the exhaust hole. When the water collection and drying mechanism starts the air intake drying, the sealing mechanism automatically opens to facilitate exhaust.

[0019] The beneficial effects of the seepage-proof and water-proof structure for urban rail construction of the present invention are as follows:

[0020] This invention uses a water collection layer, a waterproof layer, a water collection trough, and an isolation plate to prevent seepage and water leakage. The water collection and drying mechanism is connected to the water collection and concentration mechanism by a water collection pipe, which serves to collect seepage water and facilitate the drying of seepage water. The connection between the water collection troughs allows the collected seepage water to be concentrated inside the water collection and concentration mechanism. The vent is provided to allow air to enter and exit the water collection trough during drying. The sealing mechanism is provided to prevent water from overflowing from the vent during normal water collection and drainage, thus ensuring a good seepage prevention and water barrier effect after the building wall is completed.

[0021] In this invention, the water collection and drying mechanism comprises a water collection tank, a concave partition, an L-shaped partition, a fan, a heating device, a translation plate, a turntable, a connecting rod, a connecting plate, and a connecting frame, along with matching docking holes one, a round hole, a connecting groove, and docking hole two. Under normal conditions, docking hole two is connected to docking hole one on the left side of the water collection tank. At this time, the water introduced by the water collection pipe flows into the water collection tank through docking holes one, docking hole two, and the connecting groove for collection. When the turntable is rotated, the connecting rod slides along the connecting frame, thereby pulling the translation plate at the bottom of the connecting plate to move, so that docking hole two is connected to docking hole one on the right side of the water collection tank. At this time, the fan and the heating device are activated, and the heated air can be injected into multiple water collection tanks through the water collection pipe to dry the water collection tanks, which is more conducive to the anti-seepage and water-proof effect.

[0022] This invention, through the design of an air inlet, recess, actuating groove, shaft, actuating plate, engaging plate, filter screen, pressure box, piston plate, spring, clamping block, clamping opening, elastic air bladder, and ventilation pipe, ensures that under normal conditions, when the water collection pipe collects seepage water and flows into the water collection tank, the clamping block moves away from the filter screen. At this time, the filter screen can be rotated and removed from the inside of the air inlet for easy cleaning. When the fan needs to be started for drying, the sliding plate squeezes the elastic air bladder, causing the piston plate to move along the pressure box. At this time, the clamping opening on the clamping block engages with the outside of the filter screen, restricting the movement of the filter screen. Thus, when the fan is started, the filter screen will not move easily, thereby achieving the effect of filtering impurities.

[0023] The water collection mechanism of this invention comprises a water collection box, a connecting pipe, a circular block, a one-way liquid inlet valve, a one-way exhaust valve, a horizontal movable plate, a vertical movable plate, and a backing plate. These components, along with a trapezoidal water collection cavity, a vertical movable opening, a wedge-shaped opening, a first through hole, a second spring, and a second through hole, allow the following features: Under normal conditions, when the water collection box is needed to collect seepage water, the circular block can be rotated so that its outer side contacts the backing plate. At this time, the one-way liquid inlet valve connects with the first through hole, allowing the seepage water collected in the water collection tank to enter the trapezoidal water collection cavity through the one-way liquid inlet valve and then enter the water collection pipe through the connecting pipe. When hot air from a heating device needs to be blown in by a fan for drying, the circular block is rotated so that the backing plate engages with the wedge-shaped opening. At this time, the horizontal movable plate moves under the pull of the second spring, allowing the first through hole and the one-way exhaust valve to release air. This facilitates the entry of the air blown in by the fan into the water collection tank for drying while preventing backflow of water in the water collection tank, thus achieving a better drying effect.

[0024] The sealing mechanism in this invention consists of a shell, a piston block, a sealing plate, and a spring. When the fan is started and gas is introduced into the water collection tank, the piston block is pressed and slides along the inner side of the shell, squeezing the spring. This causes the sealing plate to move, opening the exhaust port to allow gas to be discharged. Attached Figure Description

[0033] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0034] According to one aspect of the invention, such as Figure 1-6 As shown, a seepage-proof and water-proof structure for urban rail construction is provided, including a water collection layer 1, a waterproof layer 2, a water collection and drying mechanism 3, a water collection and concentration mechanism 4, and a sealing mechanism 5. The waterproof layer 2 is integrally formed on the inner side of the water collection layer 1. Two water collection and drying mechanisms 3 are arranged below the water collection layer 1.

A water collection pipe 6 is fixedly connected between the water collection and drying mechanism 3 on the same side. Multiple water collection troughs 7 are opened on the upper surface of the water collection layer 1 between the two water collection and concentration mechanisms 4. Multiple through-type connecting ports 8 are opened on both sides inside the water collection troughs 7. An isolation plate 9 is fixedly connected inside the water collection trough 7 located at the center line of the water collection layer 1. The inner front surface of the 7, and both sides of the isolation plate 9, are provided with exhaust holes 10. Both sides of the isolation plate 9 are fixedly connected with sealing mechanisms 5 near the two exhaust holes 10. The present invention uses the water collection layer 1, waterproof layer 2, water collection tank 7 and isolation plate 9 to prevent seepage and water. The water collection and drying mechanism 3 and the water collection and concentration mechanism 4 are connected by a water collection pipe 6, which is used to collect seepage water on the one hand and to facilitate the drying of seepage water on the other hand. The seepage water collected is easily concentrated into the water collection and concentration mechanism 4 through the connecting port 8 between the water collection tanks 7. The exhaust holes 10 are used to exhaust air when the water collection tank 7 is being dried. The sealing mechanism 5 is used to prevent water from overflowing from the exhaust holes 10 when the water collection tank 7 is normally collecting and draining water.

[0035] In this embodiment, the water collection and drying mechanism 3 includes a water collection tank 301, a concave partition 302, an L-shaped partition 303, a fan 304, a heating device 305, a translation plate 306, a turntable 307, a connecting rod 308, a connecting plate 309, and a connecting frame 310. The concave partition 302 is fixedly connected to the upper interior of the water collection tank 301. An L-shaped partition 303 is integrally formed between the interior of the water collection tank 301 and the lower surface of the concave partition 302. The fan 304 is fixedly connected to the lower inner surface of the L-shaped partition 303. The heating device 305 is fixedly installed on the outer wall of the water collection tank 301, and the output end of the heating device 305 extends to… Above the output end of the fan 304, a sliding plate 306 is slidably connected to the inner side of the concave partition 302. A turntable 307 is rotatably connected to the upper surface of the water collection tank 301 via a rotating shaft. A connecting rod 308 is fixedly connected to the upper surface of the turntable 307. A connecting plate 309 is fixedly connected to the upper surface of the sliding plate 306. A connecting frame 310 is fixedly connected to the outer wall of the connecting plate 309. The bottom end of the connecting rod 308 extends to the inner side of the water collection tank 301 and is slidably connected to the connecting frame 310. A through-hole 11 is symmetrically opened on the lower surface of the concave partition 302. A circular hole 12 is opened on the upper surface of the sliding plate 306. The inner surface of the circular hole 12... The lower surface of the component has an integrally formed connecting groove 13, and the inner lower surface of the connecting groove 13 has two integrally formed docking holes 14. In this invention, the water collecting and drying mechanism 3 is composed of a water collecting tank 301, a concave partition 302, an L-shaped partition 303, a fan 304, a heating device 305, a translation plate 306, a turntable 307, a connecting rod 308, a connecting plate 309, and a connecting frame 310, as well as docking holes 11, 12, 13, and 14, which are provided in a coordinated manner. Under normal conditions, docking holes 14 are connected to docking holes 11 located on the left side of the water collecting tank 301. At this time, the water introduced by the water collecting pipe 6 will pass through the docking holes 11. The water flows into the collection tank 301 through the connecting hole 11, connecting hole 2 14, and connecting groove 13. When the turntable 307 is rotated, the connecting rod 308 slides along the connecting frame 310, which in turn pulls the translation plate 306 at the bottom of the connecting plate 309 to move, so that connecting hole 2 14 connects with connecting hole 11 on the right side of the collection tank 301. At this time, the fan 304 and the heating device 305 are started, and the heated air can be injected into the multiple water collection tanks 7 through the water collection pipe 6 to dry the water collection tanks 7, which is more conducive to the anti-seepage and water-proofing effect, thus ensuring that the wall surface after the building construction is completed has a good anti-seepage and water-proofing effect.

[0036] In this embodiment, an air inlet 15 is integrally formed on the outer wall of the water collection tank 301. A recess 16 is formed on the inner rear surface of the air inlet 15, and a through-type actuating groove 17 is formed on the inner rear surface of the recess 16. A shaft 18 is rotatably connected to the inside of the recess 16 via a rotating shaft. An actuating piece 19 is provided on the outer wall of the shaft 18 inside the actuating groove 17. A locking piece 20 is symmetrically fixedly connected on the outer wall of the shaft 18 inside the air inlet 15. The inner sides of the two locking pieces 20 are located inside the air inlet 15. A filter screen 21 is engaged with the inner side of the air inlet 15. A pressure box 22 is fixedly connected to the outer wall of the water collection tank 301 in front of the air inlet 15.

When the holding block 25 is moved away from the filter screen 21, the filter screen 21 can be removed from the inside of the air inlet 15 by rotation, making it easier to clean. When the fan 304 needs to be started for drying, the translation plate 306 squeezes the elastic air bag 27, causing the piston plate 23 to move along the air pressure box 22. At this time, the clamping port 26 on the holding block 25 will engage with the outside of the filter screen 21, restricting the movement of the filter screen 21. Thus, when the fan 304 is started, the filter screen 21 will not move easily, thereby achieving the effect of filtering impurities.

[0037] In this embodiment, the water collection and concentration mechanism 4 includes a water collection box 401, a connecting pipe 402, a circular block 403, a one-way inlet valve 404, a one-way exhaust valve 405, a horizontal movable plate 406, a vertical movable plate 407, and a stop plate 408. The water collection box 401 has a trapezoidal water collection cavity 29 inside.

A vertical movable plate 407 is fixedly connected to the end of the horizontal movable plate 406 away from the spring 33, located inside the vertical movable opening 30. A stop plate 408 is integrally formed at the bottom of the vertical movable plate 407. The rear end of the stop plate 408 contacts the outer wall of the circular block 403.

These components, along with a trapezoidal water collection cavity 29, a vertical movable opening 30, a wedge-shaped opening 31, a first through hole 32, a second spring 33, and a second through hole 34, are arranged in a staggered and fixed manner. This allows the circular block 403 to be rotated to contact the stop plate 408 when water seepage needs to be collected using the water collection box 401 under normal conditions. At this time, the one-way inlet valve 404... The water collection tank 7 collects seepage water through the through hole 32 and then enters the trapezoidal water collection chamber 29 through the one-way liquid inlet valve 404. It then enters the water collection pipe 6 through the connecting pipe 402. When it is necessary to blow hot air into the heating device 305 by the fan 304 for drying, the round block 403 is rotated so that the abutment plate 408 is engaged in the wedge-shaped opening 31. At this time, the horizontal movable plate 406 is pulled by the spring 33, so that the through hole 32 and the one-way exhaust valve 405 exhaust air. This allows the air blown in by the fan 304 to enter the water collection tank 7 for drying while preventing the water in the water collection tank 7 from flowing back, thereby achieving a better drying effect.

[0038] In this embodiment, a positioning hole 35 is provided on the lower surface of the water collection box 401, and a positioning bolt 36 is slidably connected inside the round block 403.

[0040] In this embodiment, the sealing mechanism 5 includes a housing 501, a piston block 502, a sealing plate 503, and a spring 504. The piston block 502 is slidably connected to the inner side of the housing 501, and the spring 504 is fixedly connected between the piston block 502 and the housing 501. The spring 504 is fixedly connected to the side of the piston block 502 away from the spring 504. The sealing mechanism 5 of the present invention, through the housing 501, piston block 502, sealing plate 503, and spring 504, enables the fan 304 to start and fill the water collection tank 7 with gas. When the piston block 502 is pressed, it will slide along the inner side of the housing 501, squeezing the spring 504, thereby moving the sealing plate 503, causing the exhaust port 10 to open and allow gas to be discharged.

[0041] According to another aspect of the present invention, a method for waterproofing and seepage prevention in urban rail construction is provided, comprising the following steps:

[0042] S1. When in use, the water collection layer 1 is attached to the top of the inner side of the tunnel to collect seepage water, and the waterproof layer 2 is attached to the inner side of the water collection layer 1 for waterproofing.

[0043] S2. The water collection and concentration mechanism 4 collects the water and then discharges it into the water collection and drying mechanism 3 through the water collection pipe 6. The water collection and drying mechanism 3 is used to collect the water collected in the multiple water collection tanks 7 opened above the water collection layer 1, which facilitates the collection of seepage water.

[0044] S3. By adjusting the connection direction of the water inlet concentrator 4, and then starting the drying function of the water collection and drying mechanism 3, the water collection tank 7 is dried.

[0045] S4. When the sealing mechanism 5 is used for water collection, it seals the exhaust port 10. When the water collection and drying mechanism 3 starts air intake drying, the sealing mechanism 5 automatically opens to facilitate exhaust.

[0046] The working principle of this device is as follows: This invention uses a water collection layer 1, a waterproof layer 2, a water collection trough 7, and an isolation plate 9 to prevent seepage and water leakage. The water collection and drying mechanism 3 and the water collection and concentration mechanism 4 are connected by a water collection pipe 6, which is used to collect seepage water on the one hand and to facilitate the drying of seepage water on the other. The seepage water collected is concentrated into the water collection and concentration mechanism 4 through the connecting port 8 between the water collection troughs 7. The vent 10 is used to vent air when the water collection trough 7 is being dried. The sealing mechanism 5 is used to prevent water from overflowing from the vent 10 when the water collection trough 7 is normally collecting and draining water, thereby ensuring a good seepage prevention and water leakage effect after the wall surface is completed.

[0047] All electrical components mentioned in this article are real-world electrical components.
