Description

Technical Field

[0001] The present application relates to the field of tunnels, and in particular to a tunnel drainage system and a construction method thereof. Background Art

[0002] Tunnels are engineering structures buried in the earth, a form of human utilization of underground space. Tunnels can be categorized as transportation tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. Tunnel structures consist of a main structure and ancillary facilities. The main structure consists of the tunnel body and portals, while ancillary facilities include car shelters, firefighting facilities, emergency communications, and drainage systems. Longer tunnels also have specialized ventilation and lighting equipment.

[0003] The utility model patent application CN205370641U discloses a highway tunnel structure, including a guard arch, which is arc-shaped and has stepped ends; main guard piles and auxiliary guard piles are provided below the ends of the guard arch; the main guard piles and auxiliary guard piles are connected together; a slide rail is provided in the middle of the guard arch, and a liftable crane is provided on the slide rail; the auxiliary guard piles are provided between the two main guard piles; a waterproof layer is provided on the inner side of the guard arch and the auxiliary guard piles; and a sewer pipe is provided at the bottom end of the waterproof layer.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when an engineering vehicle transporting mud and sand travels on the tunnel pavement, some mud and sand falls from the engineering vehicle. When it rains, rainwater carries the mud and sand into the sewer pipe, and the mud and sand accumulate in the sewer pipe and block the sewer pipe. The water on the tunnel pavement is not easy to be discharged from the sewer pipe, and the rainwater accumulates on the tunnel pavement, thereby affecting the driving of vehicles in the tunnel. Summary of the Invention

[0005] In order to improve the problem of tunnel pavement drainage, the present application provides a tunnel drainage system and a construction method thereof.

[0006] In the first aspect, the present application provides a tunnel drainage system, which adopts the following technical solutions:

[0007] A tunnel drainage system includes a drainage pipe arranged on the tunnel pavement, wherein a filter plate is connected to the inner wall of the drainage pipe close to the tunnel pavement, and the filter plate is used to filter water and sediment. A cleaning plate is connected to the drainage pipe, and the cleaning plate is used to clean the filter plate.

[0008] By adopting the above technical solution, when it rains, rainwater carries sediment along the tunnel pavement and enters the drainage pipe. The rainwater is discharged from the drainage pipe through the filter plate, while the sediment accumulates on the filter plate. The sediment is not easy to accumulate in the drainage pipe and clog the drainage pipe, thereby realizing the discharge of rainwater on the tunnel pavement and allowing the wheels to travel stably on the tunnel pavement. When too much sediment accumulates on the filter plate and poisons the filter plate, the staff drives the cleaning plate to operate and cleans the sediment accumulated on the filter plate, making it difficult for the sediment to clog the filter plate, thereby maintaining the stability of drainage in the drainage pipe.

[0009] Optionally, a control member is connected to the drainage pipe, and the control member is used to control the sliding of the cleaning plate. The control member includes a float and a transmission member. The float is slidably connected to the inner wall of the drainage pipe, and the transmission member is used to receive power from the float and drive the cleaning plate to slide. When the liquid level in the drainage pipe rises, the float slides away from the drainage pipe, and the transmission member receives power from the float and drives the cleaning plate to slide toward the filter plate. The outer wall of the cleaning plate abuts against the outer wall of the filter plate and scrapes off the mud and sand on the outer wall of the filter plate.

[0010] By adopting the above technical solution, when sediment accumulates on the surface of the filter plate, the water in the drainage pipe gathers in the drainage pipe, the liquid level in the drainage pipe rises, the water covers part of the volume of the float, and the buoyancy of the water on the float drives the float to slide away from the drainage pipe. The transmission part receives the power of the float and drives the cleaning plate to slide toward the filter plate. The outer wall of the cleaning plate abuts against the outer wall of the filter plate and scrapes off the sediment accumulated on the end face of the filter plate, thereby realizing automatic cleaning of the filter plate without the need for manual cleaning by staff, thereby reducing the use cost of the tunnel.

[0011] Optionally, it also includes a collecting pipe arranged on the tunnel pavement, the collecting pipe is located on the side of the drainage pipe close to the float, a connecting groove is opened on the inner wall of the drainage pipe close to the collecting pipe, the connecting groove is connected to the inner cavity of the collecting pipe, the outer wall of the float abuts against the notch of the connecting groove to form a seal, when the liquid level in the drainage pipe rises, the float slides in the direction away from the connecting groove, and the drainage pipe, connecting groove and collecting pipe are connected in sequence.

[0012] By adopting the above technical solution, when sediment blocks the filter plate, the liquid level in the drainage pipe rises, and the buoyancy of the water on the float drives the float to slide away from the drainage pipe. The inner cavity of the drainage pipe, the connecting groove and the inner cavity of the collection pipe are connected in sequence, and the water in the drainage pipe enters the collection pipe through the connecting groove, thereby realizing the diversion of the water in the drainage pipe and reducing the drainage pressure of the drainage pipe; at the same time, the transmission member drives the cleaning plate to slide in the direction close to the filter plate and scrape off the sediment on the outer wall of the filter plate, so that the sealing effect of the filter plate disappears, and the rainwater is discharged stably from the drainage pipe, so that the rainwater is not easily accumulated on the tunnel road surface, thereby ensuring the stability of vehicles driving in the tunnel.

[0013] Optionally, a scraper 1 is slidably connected to the inner wall of the collection pipe near the connecting groove, and the sliding direction of the scraper 1 is close to or away from the connecting groove. When the cleaning plate slides toward the filter plate, the end face of the cleaning plate is flush with the inner wall of the collection pipe. The scraper 1 slides toward the cleaning plate, and the outer wall of the scraper 1 abuts against the outer wall of the cleaning plate, and scrapes off the mud and sand adhering to the outer wall of the cleaning plate.

[0014] By adopting the above technical solution, when the cleaning plate slides toward the filter plate, the outer wall of the cleaning plate is flush with the inner wall of the collection pipe, and the scraper slides toward the cleaning plate, and the outer wall of the scraper abuts against the outer wall of the cleaning plate, and drives the mud and sand adhering to the outer wall of the cleaning plate to separate from the outer wall of the cleaning plate, thereby achieving cleaning of the cleaning plate and improving the cleaning efficiency of the cleaning plate on the filter plate.

[0015] Optionally, a buffer zone is also provided on the tunnel pavement.

[0016] By adopting the above technical solution, when vehicles are driving on the tunnel road surface, the buffer zone slows down the vehicles, making it difficult for vehicles to drive too fast and cause traffic accidents, thereby improving the safety of tunnel driving.

[0017] Optionally, the buffer belt is slidably connected to the tunnel pavement, and the sliding direction of the buffer belt is close to or away from the tunnel pavement. A connecting piece is connected to the buffer belt, and the connecting piece is used to receive the power of the buffer belt and drive the scraper to slide. When the buffer belt slides in the direction close to the tunnel pavement, the connecting piece is used to receive the power of the buffer belt and drive the scraper to slide in the direction away from the collection pipe.

[0018] By adopting the above technical solution, when a vehicle passes through the buffer zone, the gravity of the vehicle drives the buffer zone to slide toward the direction close to the tunnel road surface, and the connecting part receives the power of the buffer zone and drives scraper 1 to slide toward the direction close to the collection pipe, thereby realizing automatic sliding of scraper 1. There is no need for staff to manually control the sliding of scraper 1, thereby reducing the use cost of the tunnel.

[0019] Optionally, an elastic member 1 is provided between the buffer zone and the tunnel pavement, and the elastic force of the elastic member 1 drives the buffer zone to slide in a direction away from the tunnel pavement.

[0020] By adopting the above technical solution, when a vehicle passes through the buffer strip, the elastic force of the elastic member drives the buffer strip to slide in a direction away from the tunnel road surface, thereby achieving automatic reset of the buffer strip.

[0021] Optionally, a scraper 2 is slidably connected to the inner wall of the collection pipe, the sliding direction of the scraper 2 is parallel to the length direction of the collection pipe, and the outer wall of the scraper 2 abuts against the inner wall of the collection pipe and the outer wall of the scraper 1.

[0022] By adopting the above technical solution, scraper 2 is slidably connected to the inner wall of the collection pipe, and the outer wall of scraper 2 abuts against the inner wall of the collection pipe and the outer wall of scraper 1, driving the mud and sand adhered to the inner wall of the collection pipe and the outer wall of scraper 1 to accumulate at one end of the collection pipe, thereby realizing the collection of mud and sand in the collection pipe, thereby facilitating the cleaning of the collection pipe by the staff.

[0023] Optionally, a transmission member is connected to the collecting pipe, and the transmission member is used to drive the scraper 2 to slide. The transmission member includes a rotating screw, a bevel gear 1, a bevel gear 2 and a transmission screw, and the transmission screw is rotatably connected to the inner wall of the collecting pipe, and the axis of the transmission screw and the length direction of the collecting pipe are parallel to each other, and the bevel gear is coaxially fixed to one end of the transmission screw, and the scraper 2 is threadedly connected to the transmission screw, and the rotating screw is rotatably connected to the inner wall of the collecting pipe, and the axis of the rotating screw and the length direction of the collecting pipe are perpendicular to each other, and the end of the rotating screw protrudes from the end face of the collecting pipe, and the bevel gear 2 is coaxially fixed to one end of the rotating screw located in the collecting pipe, and the bevel gear 1 engages with the bevel gear 2. When the rotating screw rotates, it drives the scraper 2 to slide along the axis of the transmission screw.

[0024] By adopting the above technical solution, when the staff needs to clean the collection pipe, they rotate the rotating screw to drive the scraper 2 to slide along the axis of the transmission screw. The outer wall of the scraper 2 abuts against the inner wall of the collection pipe and the outer wall of the scraper 2, and drives the mud and sand on the inner wall of the collection pipe and the scraper 2 to gather on one side of the collection pipe. There is no need for the staff to walk along the tunnel pavement and drive the scraper 2 to slide in the collection pipe, thereby improving the convenience of the staff in cleaning the collection pipe.

[0044] The present application embodiment discloses a tunnel drainage system. Figure 1 A tunnel drainage system includes two drainage pipes 1 and two collection pipes 2 pre-buried in the tunnel pavement. The two drainage pipes 1 are located on either side of the tunnel pavement in the width direction. The notches of the drainage pipes 1 are flush with the tunnel pavement, and the lengths of the drainage pipes 1 and the tunnel pavement are parallel to each other. The collection pipes 2 correspond one to one with the drainage pipes 1, and are located on the side of the drainage pipes 1 away from the other drainage pipes 1.

[0045] Reference Figure 2 A sieve plate 3 is connected to the drainage pipe 1, and the outer wall of the sieve plate 3 is pressed against the inner wall of the drainage pipe 1 to fix it. A water flow channel 11 is opened on the inner wall of the drainage pipe 1 facing the sieve plate 3. A water pump 4 is pre-buried in the tunnel. The water inlet of the water pump 4 is connected to the water flow channel 11, and the water outlet of the water pump 4 is connected to the outlet pipe 5. The water pump 4 drives the water in the drainage pipe 1 into the inner cavity of the water pump 4 through the water flow channel 11 and is discharged from the outlet pipe 5, thereby draining rainwater from the tunnel road surface.

[0046] Reference Figure 1 and Figure 2 The notch of the collecting pipe 2 is higher than the notch of the drainage pipe 1. A cover plate 6 is rotatably connected to the collecting pipe 2. The rotation axis of the cover plate 6 and the length direction of the collecting pipe 2 are parallel to each other. When the cover plate 6 rotates toward the collecting pipe 2, the circumferential outer wall of the cover plate 6 presses against the inner wall of the collecting pipe 2 to achieve sealing. A handle 7 for the user to hold is welded and fixed to the outer wall of the cover plate 6.

[0047] Reference Figure 2A connecting groove 12 is provided on the inner wall of the drainage pipe 1 near the collecting pipe 2. The connecting groove 12 is a strip-shaped groove. The length direction of the connecting groove 12 is parallel to the length direction of the drainage pipe 1. The connecting groove 12 passes through the inner wall of the drainage pipe 1 toward the collecting pipe 2. The inner cavity of the drainage pipe 1, the connecting groove 12 and the inner cavity of the collecting pipe 2 are connected in sequence.

[0048] Reference Figure 2 A water filtering channel 21 is opened on the inner wall of the collecting pipe 2 facing the cover plate 6. The water filtering channel 21 is connected to the water flow channel 11. The water pump 4 drives the accumulated water in the collecting pipe 2 into the inner cavity of the water pump 4 from the water filtering channel 21 and is discharged from the water outlet pipe 5, thereby realizing the discharge of the accumulated water in the collecting pipe 2.

[0049] Reference Figure 2 A filter plate 8 is connected to the inner wall of the drainage pipe 1 near the water flow channel 11. A plurality of filter holes 81 are spaced apart on the filter plate 8. The water in the drainage pipe 1 is discharged from the filter holes 81, and the sediment gathers on the end face of the filter plate 8 to achieve the separation of sediment and water.

[0050] Reference Figure 2 A cleaning plate 9 is slidably connected to the inner wall of the drainage pipe 1, and the sliding direction of the cleaning plate 9 is close to or away from the connecting groove 12. When the cleaning plate 9 slides toward the connecting groove 12, the outer wall of the cleaning plate 9 abuts against the outer wall of the filter plate 8, and drives the mud and sand on the end face of the filter plate 8 into the inner cavity of the collection pipe 2 from the connecting groove 12, thereby cleaning the filter plate 8.

[0051] Reference Figure 2 and Figure 3 A control member 10 is connected to the drainage pipe 1, and the control member 10 is used to control the sliding of the cleaning plate 9.

When the outer wall of the float 101 abuts the notch of the connecting groove 12, the inner cavity of the drainage pipe 1 and the connecting groove 12 are separated. When the liquid level in the drainage pipe 1 rises, the buoyancy of the accumulated water on the float 101 drives the float 101 to slide in the direction away from the connecting groove 12, and the sealing effect of the float 101 on the connecting groove 12 disappears. The inner cavity of the drainage pipe 1, the connecting groove 12 and the inner cavity of the collection pipe 2 are connected in sequence.

The cleaning rack 1023 is welded and fixed to the side of the float 101 facing the cleaning gear 1022, and the cleaning gear 1022 engages with the cleaning rack 1023.

[0053] Reference Figure 2 and Figure 3 When the liquid level in the drainage pipe 1 rises, the accumulated water covers part of the volume of the float 101. The buoyancy of the accumulated water on the float 101 drives the float 101 to slide away from the drainage pipe 1. The cleaning gear 1022 rotates, driving the cleaning plate 9 to slide toward the filter plate 8. The outer wall of the cleaning plate 9 abuts against the outer wall of the filter plate 8, and drives the mud and sand on the cleaning plate 9 into the inner cavity of the collection pipe 2, realizing automatic cleaning of the filter plate 8; at the same time, the outer wall of the cleaning plate 9 abuts against the inner wall of the connecting groove 12 to achieve sealing, and the outer wall of the cleaning plate 9 is flush with the inner wall of the collection pipe 2.

The filter screen 13 is used to filter accumulated water and sediment. A scraper 14 is slidably connected to the inner wall of the collection pipe 2. The sliding direction of the scraper 14 is close to or away from the connecting groove 12. The scraper 14 is located on the side of the collection pipe 2 close to the drainage pipe 1.

The threaded hole 2 181 passes through the outer wall of the scraper 2 18 along its own axis. The transmission screw 194 is penetrated by the threaded hole 2 181, and the axis of the transmission screw 194 coincides with the axis of the threaded hole 191.

[0062] Reference Figure 2 and Figure 5 When a large amount of sediment accumulates in the inner cavity of the collection pipe 2, the staff drives the hand wheel 20 to rotate, drives the bevel gear 192 to rotate, and drives the scraper 2 18 to slide along the axis of the transmission screw 194. The outer wall of the scraper 2 18 abuts against the inner wall of the collection pipe 2 and the outer wall of the scraper 1 14, thereby cleaning the filter screen 13, the inner wall of the collection pipe 2 and the outer wall of the scraper 2 18, and drives the sediment in the collection pipe 2 to gather at one end of the inner wall of the collection pipe 2, thereby facilitating the staff to clean the sediment in the collection pipe 2.

[0063] The implementation principle of a tunnel drainage system in an embodiment of the present application is as follows: during rainfall, rainwater carries sediment along the tunnel pavement into the drainage pipe 1, and the rainwater passes through the filter hole 81, enters the inner cavity of the water pump 4, and is discharged from the outlet pipe 5, thereby achieving the separation of rainwater and sediment, making it difficult for sediment to block the water flow channel 11, thereby ensuring the stability of drainage in the drainage pipe 1, and making it difficult for water to accumulate on the tunnel pavement, thereby ensuring the stability of vehicles driving on the tunnel pavement.

[0064] When silt accumulates on the end face of the filter plate 8 and blocks the filter plate 8, the liquid level in the drainage pipe 1 rises, and rainwater covers part of the volume of the float 101. The buoyancy of the rainwater on the float 101 drives the float 101 to slide away from the connecting groove 12, and the cleaning gear 1022 rotates, driving the cleaning plate 9 to slide toward the filter plate 8. The outer wall of the cleaning plate 9 abuts against the outer wall of the filter plate 8, and drives the silt on the cleaning plate 9 into the inner cavity of the collection pipe 2, thereby realizing automatic cleaning of the filter plate 8.

[0065] At the same time, the outer wall of the cleaning plate 9 abuts against the inner wall of the connecting groove 12 to achieve sealing, and the outer wall of the cleaning plate 9 is flush with the inner wall of the collecting pipe 2. When the vehicle abuts against the end face of the buffer belt 15, the gravity of the vehicle drives the buffer belt 15 to slide toward the direction close to the tunnel road surface, and the buffer gear 172 rotates, driving the connecting gear 174 to rotate, driving the scraper 14 to slide toward the direction close to the connecting groove 12. The outer wall of the scraper 14 abuts against the outer wall of the cleaning plate 9 and drives the mud and sand to leave the end face of the cleaning plate 9, thereby realizing automatic cleaning of the cleaning plate 9.

[0066] The present application also discloses a tunnel drainage system construction method, comprising the following steps:

[0067] According to the designed position, build the portal arch and pour concrete;
