Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, and in particular to a highway drainage facility. Background Technology

[0002] Highway drainage systems are categorized into side ditch drainage, transverse drainage, and longitudinal drainage. Side ditch drainage involves digging a ditch on both sides of the roadbed to drain surface water and rainwater from surrounding areas, keeping the road surface dry and improving driving safety. Side ditch drainage is suitable for highways with flat or naturally steep terrain. It drains water to the outside of the roadbed, reducing the load on the roadbed and increasing the road's load-bearing capacity. Transverse drainage involves setting up transverse drainage ditches to prevent water accumulation on the road surface, maintaining its flatness and strength. Transverse drainage ditches are typically installed along slopes, allowing water to drain quickly while maintaining road straightness and preventing mud accumulation. Longitudinal drainage involves setting up longitudinal drainage ditches to direct surface water to the outside of the roadbed, keeping both the roadbed and pavement dry. Longitudinal drainage is suitable for highways and mountain roads, draining surface water and rainwater from surrounding areas, reducing road surface moisture, and preventing safety hazards such as roadbed landslides.

[0003] Existing transverse drainage ditches generally employ drainage channels with an "Ω"-shaped cross-section. This type of drainage channel ensures both smooth water flow and vehicle passage. Its specific structure and installation scheme can be found in CN211142724U. Although the "Ω"-shaped drainage channel is widely used, there are still areas for improvement. Because its inlet is a narrow slit, the drainage speed is relatively slow, and it easily leads to road flooding during heavy rainfall, requiring further refinement. Summary of the Invention

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a highway drainage facility.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A highway drainage facility includes a plurality of first drainage channels and second drainage channels. The plurality of first drainage channels and second drainage channels are laid on the highway surface in a transversely staggered manner. The cross-section of the drainage channel of the first drainage channel is "Ω" shaped, and the cross-section of the drainage channel of the second drainage channel is "U" shaped. The bottom surfaces of the drainage channels of the plurality of first drainage channels and second drainage channels are located on the same virtual cylindrical surface. The top surfaces of the first drainage channels and second drainage channels are flush with the highway surface. The top openings of the plurality of first drainage channels and second drainage channels are combined to form a fishbone-shaped water inlet.

[0007] Furthermore, the length of the first drainage channel is 200mm, and the length of the second drainage channel is 50mm.

[0008] The beneficial effects of this utility model are as follows: by using several first drainage channels and second drainage channels to interlock, a fishbone-shaped water inlet is formed on the highway road surface. Without sacrificing vehicle passability, the area of ​​the water inlet is increased, thereby improving the drainage speed and improving the situation where the road surface is prone to water accumulation in rainy weather.

[0010] Figure 2 This is an exploded view of an embodiment of the present utility model.

[0011] Explanation of the attached diagram numbers: 1. First drainage ditch; 2. Second drainage ditch; 3. Highway pavement. Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0013] like Figure 1-2 As shown, a highway drainage facility includes several first drainage channels 1 and second drainage channels 2. The several first drainage channels 1 and second drainage channels 2 are laid on the highway surface 3 in a transversely staggered manner. The cross-section of the drainage channel of the first drainage channel 1 is "Ω" shaped, and the cross-section of the drainage channel of the second drainage channel 2 is "U" shaped. The bottom surfaces of the drainage channels of the several first drainage channels 1 and second drainage channels 2 are located on the same virtual cylindrical surface. The top surfaces of the first drainage channels 1 and second drainage channels 2 are flush with the highway surface 3. The top openings of the several first drainage channels 1 and second drainage channels 2 are combined to form a fishbone-shaped water inlet. The length of the first drainage channel 1 is 200 mm, and the length of the second drainage channel 2 is 50 mm.

[0014] Compared to the traditional method of using drainage channels with an "Ω" shaped cross-section as a lateral drainage measure, this device improves the drainage outlet to a fishbone shape. This not only does not sacrifice the vehicle's passability or the stability of the entire device, but also increases the area of ​​the water inlet, which can improve the water intake speed and improve the situation where the road surface is prone to water accumulation in rainy weather.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
