The main purpose of these structures is to prevent rainwater accumulation, reduce the flood risk, maintain road facilities and ensure the normal operation of urban traffic.
[0003] In the existing road surface drainage ditch, the openings in the upper drainage plate are of a fixed structure. In the later stage, when it does not rain, the odor in the drainage ditch will flow out from the drainage plate, affecting the surrounding air. And when the rain is getting heavier on a rainy day, the fixed water inlet drainage holes will, to a certain extent, affect the speed of rainwater flowing into the drainage ditch. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a road drainage structure for municipal engineering, which can block the water outlet holes when it does not rain, reduce the overflow of peculiar smell from the drainage ditch, and can change the size of the water outlet holes according to the impact of rainwater.
[0005] To achieve the above object, the utility model provides the following technical solution: A road drainage structure for municipal engineering is applied to a road. A sewer is arranged vertically on the road. An outer protection box and an inner anti-slip box are arranged in the sewer.

[0025] Embodiment 1:
[0026] Please combine Figures 1 to 3As shown in the figure, the utility model provides a road drainage structure for municipal engineering, which is applied to Road 1. A sewer 2 is arranged vertically on Road 1. An outer protection box 5 and an inner anti-slip box 6 are arranged in the sewer 2. The inner protection box 6 is fixedly connected to the inner side wall of the outer anti-slip box 5. A plurality of through hydrophobic holes 51 are arranged on the bottom side wall of the outer protection box 5. A plurality of through hydrophobic holes 9 are arranged on the side wall of the inner protection box 6. Filter nets 91 are fixedly connected to the side walls of the plurality of hydrophobic holes 9.
[0027] A plurality of connecting springs 7 are fixedly connected to the inner bottom wall of the inner protection box 6. The upper ends of the plurality of connecting springs 7 are fixedly connected to a sealing plate 8. The sealing plate 8 can slide up and down on the side wall of the inner protection box 6.
[0028] When it rains, the impact force of the rainwater flushes the sealing plate 8 to move downward, exposing the plurality of hydrophobic holes 9. The greater the rain, the greater the impact force of the rain, the greater the pressure on the connecting springs 7, and the larger the exposed area of the hydrophobic holes 9, so that the rainwater flows out faster. If the impact force of the rainwater is small, as the rainwater accumulated on the sealing plate 8 becomes heavier and heavier, it will also press the connecting springs 7 to contract, exposing the hydrophobic holes 9 to allow the internal water to flow out. When there is no rainwater, the sealing plate 8 is located above the plurality of hydrophobic holes 9 under the elastic force of the connecting springs 7, making the opening of the inner protection box 6 in a closed state, thereby preventing the odor in the drainage channel 3 from overflowing and affecting the surrounding environment.
[0029] On the basis of Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods. For details, see the following description.
[0030] Embodiment 2:
[0031] A hanging structure is arranged at the upper end of the outer protection box 5. The hanging structure includes two hanging ears 12. The two hanging ears 12 are respectively fixedly connected to the two upper side walls of the outer protection box 5. Connecting ropes 13 are arranged on the two hanging ears 12. A connecting ring 14 is arranged between the two connecting ropes 13. A connecting rope 15 is arranged on the connecting ring 14. The upper end of the connecting rope 15 is fixedly connected to a locking hook 16.
[0032] By hanging the locking hook 16 at the groove 41 on the manhole cover 4, when some items such as coins, key rings, etc. fall into the sewer 2 and land on the sealing plate 8, when it is necessary to fish them out, only need to pull the connecting rope 15 upward, and the entire outer protection box 5 will move upward, then the dropped things can be taken out.
[0033] A drainage channel 3 is horizontally arranged on Road 1. The sewer 2 communicates with the drainage channel 3. An anti-backflow structure is provided in the drainage channel 3. The anti-backflow structure includes an anti-backflow plate 10. The anti-backflow plate 10 is connected to the drainage channel 3 through a hinge. A first limiting plate 11 is fixedly connected to the side wall of the drainage channel 3.
[0034] Due to factors such as overdevelopment, imperfect drainage systems, and the possible blockage of drainage outlets for various reasons, in the case of heavy rainfall and other large amounts of precipitation, the water in the sewer flows back into people's living areas or buildings. When the water is flowing normally in the drainage channel 3, the impact force of the water will cause the anti-backflow plate 10 to rotate upward, ensuring the smoothness of the drainage channel 3. Once the water flow reverses, the anti-backflow plate 10 will be in a vertical state under the action of its own gravity, blocking the drainage channel 3 to prevent water from flowing back. And under the action of the first limiting plate 11, the reverse water flow will not cause the anti-backflow plate 10 to rotate left and upward.
[0035] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any ordinary technician in the industry can smoothly implement the present invention according to the illustrations in the specification and the above description. However, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention, by using the technical content disclosed above and making some modifications, decorations, and evolutions, are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the substantial technology of the present invention still fall within the protection scope of the technical solution of the present invention.
