Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a road drainage structure. Background Art

[0002] After rainfall, water usually accumulates on the road. Water accumulation on the road surface will bring many effects. For example, water seeping into the road structure will soften the roadbed, reduce its bearing capacity, and cause road settlement, cracking and other problems. Water accumulation on the road surface will also reduce friction on the road surface, making it easy to slip, etc. Therefore, a good drainage system is essential for road safety.

[0003] The current road drainage structure is usually quantitative drainage, and the drainage speed cannot be changed according to the amount of water accumulation, resulting in the inability to drain quickly when there is a lot of water accumulation. Utility Model Content

[0004] The main purpose of the utility model is to provide a road drainage structure, which aims to quickly drain the accumulated water when there is a lot of water on the road.

[0005] In order to achieve the above-mentioned purpose, the road drainage structure proposed in the utility model comprises:

[0006] pavement;

[0007] a drainage channel, the drainage channel being opened at the edge of the road surface;

[0008] A cover plate, the cover plate is arranged on the drainage channel and is flush with the road surface;

[0009] A drainage board, wherein the drainage board is provided with drainage holes and covers the drainage channel, and the drainage board and the cover board are arranged alternately;

[0010] An elastic member supports the drainage board to be flush with the road surface.

[0011] Optionally, in an embodiment of the present utility model, the drainage channel has a limiting step, the limiting step is higher than the bottom end of the elastic member and lower than the drainage board, and the limiting step limits the drainage board.

[0012] Optionally, in an embodiment of the utility model, the drainage channel also includes a supporting portion, the supporting portion is connected to the drainage channel, the supporting portion is higher than the bottom wall of the drainage channel, one end of the elastic member is connected to the supporting portion, and the other end is connected to the drainage board.

[0013] Optionally, in an embodiment of the present invention, the drainage plate is connected to the elastic member.

[0014] Optionally, in an embodiment of the present invention, the drainage channel is provided with a receiving hole, and the elastic member is located in the receiving hole.

[0015] Optionally, in an embodiment of the present invention, a plurality of elastic members are provided.

[0016] Optionally, in an embodiment of the present invention, the elastic member is a spring.

[0017] Optionally, in an embodiment of the present utility model, the drainage board has a filter screen, and the filter screen is located in the drainage hole.

[0018] Optionally, in an embodiment of the present invention, the drainage holes and the elastic members are arranged alternately.

[0019] Optionally, in an embodiment of the present invention, the drainage hole is gradually tightened along the direction from the drainage plate to the drainage channel.

[0020] Compared with the prior art, the utility model can at least achieve the following beneficial effects. When water accumulates on the road, the accumulated water flows into the drainage channel through the drainage holes of the drainage board to achieve drainage. In the process of drainage, the water flow tends to converge in the direction of the drainage holes, which increases the amount of water accumulated at the drainage board. Under the action of the accumulated water pressure, the drainage board presses down the elastic part, gradually lowering it below the road surface to form a low-lying area, accelerating the flow of water to converge here and enter the drainage channel through the drainage holes, so that the accumulated water can be quickly discharged when there is too much water. As the accumulated water is gradually drained away, the accumulated water at the drainage board gradually decreases, and the elastic part drives the drainage board to gradually move up until it is flush with the road surface, ensuring the aesthetics of the road.

[0033] Reference Figure 1~Figure 4 The utility model provides a road drainage structure, the drainage structure comprising:

[0034] Pavement 100;

[0035] A drainage channel 200 is provided at the edge of the road surface 100;

[0036] A cover plate 300 , which is disposed on the drainage channel 200 and is flush with the road surface 100 ;

[0037] A drainage plate 400, the drainage plate 400 is provided with a drainage hole 410 and is covered on the drainage channel 200, and the drainage plate 400 and the cover plate 300 are arranged in a staggered manner;

[0038] The elastic member 500 supports the drainage board 400 to be flush with the road surface 100 .

[0039] When water accumulates on the road, the accumulated water flows into the drainage channel 200 through the drainage holes 410 of the drainage board 400 to achieve drainage. In the process of drainage, the water flow tends to converge in the direction of the drainage holes 410, so that the accumulated water at the drainage board 400 increases. Under the action of the accumulated water pressure, the drainage board 400 presses down the elastic member 500, gradually lowering it from the road surface 100 to form a low-lying area, accelerating the flow of water to converge there and enter the drainage channel 200 through the drainage holes 410, so as to achieve rapid drainage of the accumulated water when there is too much accumulated water. As the accumulated water is gradually drained away, the accumulated water at the drainage board 400 gradually decreases, and the elastic member 500 drives the drainage board 400 to gradually move up until it is flush with the road surface 100, ensuring the aesthetics of the road. In addition, in order to allow the accumulated water to flow quickly through the drainage holes 410, the structure of the drainage holes 410 is set to a structure that gradually tightens from top to bottom to increase the drainage speed.

[0040] Since the water discharged by road drainage is mostly rainwater, it is necessary to consider the corrosion of components by rainwater, especially the impact of rainwater on the elastic member 500, which is a core component.

[0041] Preferably, the elastic member 500 is selected as a spring, and multiple springs are provided. The material of the spring can be stainless steel with alloy elements such as Cr and Ni added to enhance its corrosion resistance. In addition, the spring is arranged to be staggered with the drain hole 410 to reduce the contact between the accumulated water and the spring when draining, thereby increasing the service life of the spring.

[0042] The drain plate 400 and the spring are designed as a connection structure. When the drain channel 200 needs to be cleaned, the drain plate 400 is moved to work on the drain channel 200. The drain plate 400 is connected to the spring. When the drain plate 400 is moved, the spring is taken out at the same time to reduce the impact of the spring on the cleaning work. The spring can be fixedly connected to the drain plate 400 or detachably connected. When the detachable connection is used, it can be replaced separately when one of the two has a problem. At the same time, a receiving hole 230 is opened in the drain channel 200 to position the spring and enable it to be stably located in the drain channel 200.

[0043] Furthermore, the drainage channel 200 has a limiting step 220 . The limiting step 220 is higher than the bottom end of the elastic member 500 and lower than the drainage board 400 . The limiting step 220 limits the drainage board 400 .

[0044] Since the drain plate 400 is suspended on the drain channel 200 under the support of the elastic member 500, a longer spring may cause the drain plate 400 to be unable to be stably suspended or the drain plate 400 may have difficulty in pressing down the spring. Therefore, a support portion 210 is provided in the drain channel 200. The connection between the support portion 210 and the drain channel 200 may be provided by providing a pillar or other components at the bottom of the drain channel 200 to support the support portion 210, or the support portion 210 may be provided as a structure connected to the inner wall of the drain channel 200, as long as the support portion 210 can be stably located in the drain channel 200. The support portion 210 is provided to reduce the length of the elastic member 500 and improve the stability of the elastic member 500 in supporting the drain plate 400. It is understandable that after the support portion 210 is provided, the accommodating cavity is opened in the support portion 210.

[0045] In addition, the suspension of the drain board 400 makes it impossible for the drain board 400 to provide stable support for objects on the drain board 400. In order to prevent pedestrians from stepping on the drain board 400 and causing sprains or jams, a limit step 220 is opened in the drain channel 200. The limit step 220 is higher than the bottom end of the elastic member 500 of the drain channel 200 and lower than the drain board 400. When the drain board 400 moves down to a certain extent, the limit step 220 provides support for the drain board 400 to prevent it from moving down excessively.

[0046] During the drainage process, the accumulated water on the road will flow into the drainage channel 200 along with a large amount of debris, which may easily cause the drainage channel 200 to be blocked, affecting drainage. Therefore, a filter 420 is provided at the drainage hole 410 to prevent debris from entering the drainage channel 200 and causing blockage. In addition, items such as keys and mobile phones may also fall into the drainage hole 410, and the filter 420 can also prevent these items from falling into it.

[0047] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
