Description

Technical Field

[0001] This utility model relates to the field of tunnel drainage technology, specifically a drainage structure for tunnels. Background Technology

[0002] Tunnels are typically located underground, surrounded by rock and soil. Groundwater can seep into the tunnel through various pathways, such as pores and fissures in the rock and soil. If the water inside the tunnel cannot be drained in time, it can seriously affect the tunnel's structural safety and normal operation.

[0003] A search revealed a utility model patent with Chinese patent publication number CN214247407U, which discloses a drainage structure for tunnels, including a drainage pipe, a secondary drainage pipe, a fixing component, and a seepage trough. The drainage pipe is arranged longitudinally along the bottom of the tunnel, and its bottom end is fixedly connected to the fixing component. A pipe placement groove is arranged longitudinally on the outer side of the drainage pipe. The seepage trough is located below the bottom wall of the tunnel and is V-shaped.

[0004] As the branches of the drainage system, secondary drainage pipes, especially in mountain tunnels, often suffer from blockages caused by crystallization. These crystals can cause various problems, and in severe cases, they can affect the structural safety of the tunnel. For concealed drainage structures, the cleaning process is inconvenient, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a drainage structure for tunnels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for tunnels, including a road surface, with a water collection trough on both sides of the top outer wall of the road surface, a drainage transverse trough inside the road surface, both water collection troughs being connected to the drainage transverse trough, a drainage longitudinal trough inside the road surface, the drainage transverse trough and the drainage longitudinal trough being connected, a cleaning component installed inside the drainage transverse trough and the two water collection troughs, the cleaning component including two conveying longitudinal pipes fixedly connected to the inner wall of the two water collection troughs on opposite sides, one end of the two conveying longitudinal pipes being fixedly connected to a conveying transverse trough, the conveying transverse trough being inside the drainage transverse trough, and several cleaning nozzles evenly distributed at the bottom of the conveying transverse trough and the two conveying longitudinal pipes.

[0007] As a further preferred embodiment of this technical solution, a pre-buried well is placed on the top of the road surface and is located inside the tunnel. A water pump is fixedly installed on the top of the pre-buried well by a bracket. The water inlet of the water pump extends into the interior of the pre-buried well, and a water outlet is fixedly connected to the water outlet of the water pump. The water outlet is connected to two longitudinal conveying pipes through a connecting pipe.

[0008] It can clean crystals in the drainage system. The working process is simple and convenient. It can also push other settled mud and sand and other impurities into the drainage trough, which helps to improve the service life of the drainage system. The solution enters the two conveying longitudinal pipes through the outlet pipe and connecting pipe, and then enters the conveying transverse trough. Subsequently, it is sprayed outward through the cleaning nozzles at the bottom of the conveying longitudinal pipes and the conveying transverse trough. The solution can dissolve the crystals that are generated.

[0009] As a further preferred embodiment of this technical solution, several of the cleaning nozzles are arranged at an angle, with the top cleaning nozzle facing the direction of the drainage horizontal channel and the bottom cleaning nozzle facing the direction of the drainage vertical channel.

[0010] As a further preferred embodiment of this technical solution, both of the water collection tanks are equipped with a grid assembly. The grid assembly includes two extension strips provided on the inner walls of both sides of the water collection tank. Several grid bodies are slidably inserted into the water collection tank, and the several grid bodies are all located at the top of the two extension strips.

[0011] As a further preferred embodiment of this technical solution, each of the several extension strips has a limiting groove at one end, and each of the several extension strips has a locking block that cooperates with the limiting groove at the other end, and the several locking blocks are slidably inserted into the several limiting grooves respectively.

[0012] The grating assembly is located at the top of the conveying longitudinal pipe. Its presence ensures that the conveying longitudinal pipe will not be damaged by external factors. Accumulated water can enter the water collection tank through the through hole. The limiting groove and the locking block of the grating body cooperate with each other, so that the relevant components can support each other and prevent them from falling out of the water collection tank at will. The disassembly operation is also relatively convenient.

[0013] As a further preferred embodiment of this technical solution, a supporting horizontal pipe is provided inside the drainage horizontal channel, and a supporting vertical pipe is provided inside the drainage vertical channel, with the supporting horizontal pipe and the supporting vertical pipe connected together.

[0014] As a further preferred embodiment of this technical solution, both the supporting horizontal tube and the supporting vertical tube are made of carbon steel and are covered with stainless steel.

[0015] This utility model provides a drainage structure for tunnels, which has the following beneficial effects:

[0016] (1) By setting up a cleaning component, this utility model can clean the crystals in the drainage system. The working process is simple and convenient. It can also push other settled mud and sand and other impurities into the drainage longitudinal channel, which is conducive to improving the service life of the drainage system. The solution enters the two conveying longitudinal pipes through the outlet pipe and the connecting pipe, and then enters the conveying transverse channel. Subsequently, it is sprayed outward through the cleaning nozzles at the bottom of the conveying longitudinal pipes and the conveying transverse channel. The solution can dissolve the generated crystals. And because the cleaning nozzles are in an inclined state, the solution flow sprayed from the top cleaning nozzle can gradually push the mud and sand debris inside the water collection tank into the drainage transverse channel. The solution flow sprayed from the bottom cleaning nozzle can push the mud and sand debris inside the supporting transverse pipe into the supporting longitudinal pipe.

[0017] (2) By setting up a grid assembly, the grid assembly is set at the top of the conveying longitudinal pipe. Its existence can ensure that the conveying longitudinal pipe will not be damaged by external factors. Accumulated water can enter the water collection tank through the through hole. The limiting groove and the locking block of the grid body cooperate with each other, so that the relevant components can help each other and avoid being arbitrarily removed from the water collection tank. The disassembly operation is also relatively convenient. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 4As shown, in this embodiment, a drainage structure for a tunnel includes a road surface 1. A water collection trough 4 is provided on both sides of the top outer wall of the road surface 1. A drainage transverse trough 5 is provided inside the road surface 1. Both water collection troughs 4 are connected to the drainage transverse trough 5. A drainage longitudinal trough 6 is provided inside the road surface 1. The drainage transverse trough 5 and the drainage longitudinal trough 6 are connected. The same cleaning component 7 is installed inside the drainage transverse trough 5 and the two water collection troughs 4. The cleaning component 7 includes two conveying longitudinal pipes 701 fixedly connected to the inner wall of the two water collection troughs on opposite sides. One end of the two conveying longitudinal pipes 701 is fixedly connected to a conveying transverse trough 702. The conveying transverse trough 702 is located inside the drainage transverse trough 5. Several cleaning nozzles 703 are provided at equal intervals at the bottom of the conveying transverse trough 702 and the two conveying longitudinal pipes 701.

[0025] A pre-buried well 705 is placed on the top of the road surface 1 and is located inside the tunnel. A water pump 706 is fixedly installed on the top of the pre-buried well 705 by a bracket. The water inlet of the water pump 706 extends into the interior of the pre-buried well 705, and a water outlet pipe 704 is fixedly inserted into the water outlet of the water pump 706. The water outlet pipe 704 is connected to two longitudinal conveying pipes 701 through a connecting pipe.

[0026] Several cleaning nozzles 703 are all set at an angle, with the top cleaning nozzle 703 facing the direction of the drainage horizontal channel 5 and the bottom cleaning nozzle 703 facing the direction of the drainage vertical channel 6.

[0027] If crystallization occurs inside the water collection tank 4 and the supporting horizontal pipe 2, water and de-crystallizing agent are added to the pre-buried well 705. After dissolution, the water pump 706 at the top of the pre-buried well 705 is started. The solution enters the two conveying vertical pipes 701 through the outlet pipe 704 and the connecting pipe, and then enters the conveying horizontal trough 702. Subsequently, it is sprayed outward through the cleaning nozzles 703 at the bottom of the conveying vertical pipes 701 and the conveying horizontal trough 702. The solution can dissolve the crystals generated. Furthermore, since the cleaning nozzles 703 are in an inclined state, the solution flow sprayed from the top cleaning nozzles 703 can gradually push the mud and sand debris inside the water collection tank 4 into the drainage horizontal trough 5, and the solution flow sprayed from the bottom cleaning nozzles 703 can push the mud and sand debris inside the supporting horizontal pipe 2 into the supporting vertical pipe 3.

[0028] like Figure 1 and Figure 3 As shown, both water collection tanks 4 are equipped with a grid assembly 8. The grid assembly 8 includes two extension strips 801 set on the inner walls of both sides of the water collection tank 4. Several grid bodies 802 are slidably inserted into the water collection tank 4, and the several grid bodies 802 are all located at the top of the two extension strips 801.

[0029] Each of the extension strips 801 has a limiting groove 803 at one end and a locking block 804 that cooperates with the limiting groove 803 at the other end. The locking blocks 804 are slidably inserted into the limiting grooves 803 respectively.

[0030] The grid assembly 8 is set on the top of the conveying longitudinal pipe 701. Its presence ensures that the conveying longitudinal pipe 701 will not be damaged by external factors. Accumulated water can enter the water collection tank 4 through the through hole. The limiting groove 803 and the locking block 804 of the grid body 802 cooperate with each other so that the relevant components can help each other and prevent them from falling out of the water collection tank 4 at will. The disassembly operation is also relatively convenient.

[0031] like Figure 1 and Figure 2 As shown, a supporting horizontal pipe 2 is installed inside the drainage horizontal channel 5, and a supporting vertical pipe 3 is installed inside the drainage vertical channel 6. The supporting horizontal pipe 2 and the supporting vertical pipe 3 are connected.

[0032] Both the horizontal support pipe 2 and the vertical support pipe 3 are made of carbon steel and are covered with stainless steel. This prevents the water collection trough 4 and the drainage horizontal trough 5 from shrinking due to road surface settlement during use and also prevents them from being damaged by rainwater corrosion.

[0033] This utility model provides a drainage structure for tunnels, the specific working principle of which is as follows:

[0034] When the device is working, the accumulated water above the road surface 1 falls through the through holes of the main body 802 of the grid into the water collection tanks 4 on both sides. Then, it flows along the water collection tanks 4 into the supporting horizontal pipes 2 of the drainage transverse trough 5, and finally into the supporting vertical pipes 3 of the drainage longitudinal trough 6. If crystallization occurs inside the water collection tanks 4 and the supporting horizontal pipes 2, water and de-crystallizing agent are added to the pre-buried well 705. After dissolution, the water pump 706 at the top of the pre-buried well 705 is started. The solution enters the two conveying vertical pipes 701 through the outlet pipe 704 and the connecting pipe, and then enters the conveying transverse trough 702. Subsequently, it is sprayed outward through the cleaning nozzles 703 at the bottom of the conveying vertical pipes 701 and the conveying transverse trough 702. The solution can dissolve the crystals produced, and due to the cleaning... The nozzle 703 is tilted. The solution flow sprayed by the top cleaning nozzle 703 can gradually push the mud and debris inside the water collection tank 4 into the drainage horizontal channel 5. The solution flow sprayed by the bottom cleaning nozzle 703 can push the mud and debris inside the support horizontal pipe 2 into the support vertical pipe 3. The concentrated solution flow can also dissolve the crystals inside the drainage vertical channel 6. The grid assembly 8 is set on the top of the conveying vertical pipe 701. Its presence can ensure that the conveying vertical pipe 701 will not be damaged by external factors. Accumulated water can enter the water collection tank 4 through the through hole. The limiting groove 803 and the locking block 804 of the grid body 802 cooperate with each other so that the relevant components can help each other and prevent them from falling out of the water collection tank 4 at will. The disassembly operation is also relatively convenient.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
