Description

Technical Field

[0001] This utility model mainly relates to the field of road drainage technology, specifically a highway drainage system. Background Technology

[0002] During the construction of highways, drainage ditches are typically excavated at the bottom of the slopes on both sides. These ditches run along the highway's direction, allowing rainwater from the road surface to seep into them, evaporate, or be diverted to water collection facilities for treatment and reuse. To ensure the safe operation of highways, these drainage ditches are quite wide and deep, requiring the use of a significant amount of arable land. Given that my country has hundreds of thousands of kilometers of highways, the construction of these ditches results in the substantial occupation of arable land.

[0003] Existing technologies include chutes installed along the slope direction and culverts buried underground on the outer side of the slope. Water from the highway is drained into the culverts through the chutes, eliminating the need for drainage ditches. However, the chutes are located on the outer wall of the highway, and their connection with the culverts is directly exposed. During use, they are susceptible to damage from wind, sun, and human interference, which can affect the stability of the drainage system. Utility Model Content

[0004] The purpose of this invention is to provide a highway drainage system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highway drainage system, comprising a highway body laid on the ground, water storage tanks on both sides of the top of the highway body, multiple drainage outlets formed on the water storage tanks, the drainage outlets extending towards the ground along the slope direction inside the highway body, culverts buried in the ground, water purification structures connected to the ends of the drainage outlets, and a drain outlet formed at the connection between any of the water purification structures and the culverts, and a cleaning and inspection trough formed on the slope of the highway body corresponding to the water purification structure, the cleaning and inspection trough being equipped with a switch window.

[0006] Preferably, the water purification structure includes an inlet pipe, a filter pipe, and an outlet pipe connected sequentially from top to bottom. The top end of the inlet pipe is connected to the drain outlet, and the bottom end of the filter pipe is connected to the drain outlet. A filter plate is provided on the inner wall of the filter pipe, which filters the water flow and accumulates impurities on the top of the filter plate.

[0007] Furthermore, the filter tube has a cleaning port corresponding to the cleaning tank. The inner walls of the cleaning port are L-shaped. Multiple rubber blocks are provided on the cleaning port. A sealing cap that fits the cleaning port is provided on the cleaning port. The sealing cap has a locking hole corresponding to the rubber block. Waterproof tape is provided at the connection between the sealing cap and the cleaning port. The cleaning port is sealed by the waterproof tape and the sealing cap.

[0008] Preferably, a manhole cover is provided on the top of the drain outlet, and the manhole cover is engaged with the bottom of the water storage tank to perform initial screening of the water in the water storage tank.

[0009] Preferably, the inner wall of the drain outlet is covered with a smooth coating, which is a smooth material with a low friction factor, preferably fiberglass. The smooth coating reduces the friction between the water and the drain outlet, thereby increasing the water flow rate.

[0010] Preferably, the drain outlet is provided with multiple guide plates, which are airfoil structures with their airfoil tips facing the end of the drain outlet. The guide plates guide the water in the drain outlet to increase the water flow velocity.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention provides a highway drainage system that discharges water from the top of the highway body to the culvert through a water storage tank and a drainage outlet. The water is protected by the outer wall of the highway body. The interior of the water purification structure is connected to the exterior of the highway body by a cleaning port and a cleaning tank, and is sealed and protected by a sealing cover, waterproof tape and a switch door arranged sequentially from the inside to the outside. This facilitates the cleaning and inspection of impurities accumulated inside the water purification structure. The drainage system has strong overall stability.

[0013] 2. The highway drainage system provided by this utility model reduces the friction of water flow by covering the inner wall of the drainage outlet with a smooth fiberglass coating. The airfoil guide plate inside the drainage outlet guides the water with its airfoil tip facing the bottom of the drainage outlet, further avoiding water collision with the smooth coating. The smooth coating and the guide plate work together to increase the water flow velocity in the drainage outlet, thereby improving drainage efficiency.

[0014] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 5 As shown, a highway drainage system includes a highway body 2 laid on the ground 1. Water storage tanks 3 are formed on both sides of the top of the highway body 2. Arc-shaped edges 10 are formed on the top of the side walls of the water storage tanks 3, guiding water from the highway body 2 into the water storage tanks 3. Multiple drainage outlets 7 are formed on the water storage tanks 3. Manhole covers 4 are installed on the top of each drainage outlet 7, and the manhole covers 4 are engaged with the bottom of the water storage tanks 3. The drainage outlets 7 extend from the highway body 2 along the slope towards the ground 1. A culvert 5 is buried within the ground 1. A water purification structure 12 is connected to the end of each drainage outlet 7. A drain outlet 22 is formed at the connection point between any of the water purification structures 12 and the culvert 5. A cleaning and inspection trough 11 is formed on the slope of the highway body 2 at a position corresponding to the water purification structure 12. A switch window 6 is provided on the cleaning and inspection trough 11.

[0027] The water purification structure 12 includes an inlet pipe 13, a filter pipe 14, and an outlet pipe 15 connected sequentially from top to bottom. The top end of the inlet pipe 13 is connected to the drain outlet 7, and the bottom end of the filter pipe 14 is connected to the drain outlet 22. The diameter of the filter pipe 14 is twice that of the inlet pipe 13. The inlet pipe 13 and the outlet pipe 15 have the same structure. A filter plate 16 is provided on the bottom inner wall of the filter pipe 14. After the water is filtered of impurities by the filter plate 16, it flows into the culvert 5 through the drain outlet 22. The impurities accumulate above the filter plate 16.

[0028] The filter tube 14 has a cleaning port 17 corresponding to the cleaning tank 11. The inner walls of the cleaning port 17 are L-shaped, and four rubber blocks 18 are arranged at a radial position perpendicular to any one of the L-shaped inner walls. There are a total of eight rubber blocks 18. A sealing cover 19 is provided on the cleaning port 17 to fit it. The sealing cover 19 has a locking hole 20, and the number of locking holes 20 is the same as the number of rubber blocks 18 and they correspond one-to-one. Waterproof tape 21 is pasted on the outside of the connection between the sealing cover 19 and the cleaning port 17. The drain outlet 7 and the water purification structure 12 are both protected inside the highway body 2. The inside of the water purification structure 12 is connected and sealed to the outside of the highway body 2 through the sealing cover 19, the cleaning port 17 and the switch window 6, which facilitates the cleaning and inspection of the impurities accumulated inside the water purification structure 12.

[0029] The inner wall of the drain outlet 7 is covered with a smooth coating 8. The smooth coating 8 is a smooth material with a low friction factor, preferably fiberglass. Multiple guide plates 9 are arranged inside the drain outlet 7 along the drainage direction. The guide plates 9 have an airfoil structure with the airfoil tip facing the end of the drain outlet 7. When the water flows in the drain outlet 7, it is guided by the guide plates 9 to flow towards the bottom of the drain outlet 7. There is less friction and collision between the water and the smooth coating 8, and the friction force generated by the water colliding with the smooth coating 8 is also low. The water flow velocity in the drain outlet 7 is fast.
