Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3A highway pavement drainage structure includes: a highway body 1, an asphalt pavement 7 on the upper surface of the highway body 1, and side drainage channels 2 on both sides of the asphalt pavement 7. A filter screen 3 is installed above the side drainage channels 2, the filter screen 3 being evenly distributed along the upper surface of the side drainage channels 2, and the side drainage channels 2 being symmetrically distributed about the vertical centerline of the highway body 1. The filter screen 3 facilitates the flow of rainwater from both sides of the pavement into the side drainage channels 2, while also trapping larger debris such as leaves and branches. The side drainage channels 2 are equipped with... The filter tank 5 is equipped with a coarse filter media 6 inside. A water flow channel 4 is provided at the bottom of the filter tank 5, and the bottom of the water flow channel 4 is connected to a main drain pipe 15. The filter tank 5 and the side drainage channel 2 are interlocked. The coarse filter media 6 is evenly distributed along the inside of the filter tank 5. The side drainage channel 2 is connected to the main drain pipe 15 through the water flow channel 4. The coarse filter media 6 in the filter tank 5 can filter the incoming rainwater. The filtered rainwater can be easily guided to the main drain pipe 15 through the water flow channel 4.

[0025] Please see Figure 1 , 3 4. A highway pavement drainage structure, comprising: a filter manhole cover 10, installed in the middle of an asphalt pavement 7, with drainage holes 11 inside the filter manhole cover 10; the filter manhole cover 10 interlocks with the highway body 1, and the drainage holes 11 are equidistantly distributed along the interior of the filter manhole cover 10; the filter manhole cover 10 facilitates the flow of rainwater from the middle of the highway body 1 into an interception box 8, and the drainage holes 11 can intercept larger debris such as leaves and branches; an interception box 8 is installed below the filter manhole cover 10, and filter holes 9 are provided at both ends of the interception box 8; the interception box 8 corresponds to the position of the filter manhole cover 10, and the filter holes 9 are equidistantly distributed along both ends of the interception box 8; the filter holes 9 can filter the rainwater in the interception box 8, facilitating further removal of debris from the rainwater; and a drainage channel 12, which is set in the interception box. Below the drainage channel 12, on both sides of the 8, a filter box 13 is installed, and the filter box 13 is filled with fine filter media 14. The fine filter media 14 in the filter box 13 in the drainage channel 12 can filter the mud and impurities in the rainwater, thereby preventing the impurities from clogging the main drainage pipe 15. The interception box 8 is connected to the main drainage pipe 15 through the drainage channel 12 and the filter box 13. The interception box 8 is detachably connected to the highway body 1, and the filter fence 3 and the filter well cover 10 are also detachably connected to the highway body 1.

[0026] Working principle: When using this highway pavement drainage structure, firstly, the main drainage pipe 15 within the highway is installed at its outer end, flowing to the river. Rainwater in the middle of the road surface flows through the filter manhole cover 10 into the interception box 8. Simultaneously, the drainage holes 11 intercept larger debris such as leaves and branches. Then, the rainwater in the interception box 8 is filtered through the filter holes 9 and the mesh surface at the bottom of the interception box 8, further removing debris. Next, the filtered rainwater flows through the drainage channel 12 into the filter box 13. The fine filter media 14 in the filter box 13 filters out mud and impurities in the rainwater, preventing blockage of the main drainage pipe 15. The filtered rainwater then flows into the main drainage pipe 15. Then, the road surface... When there is a lot of water, it will flow into the side drainage channels 2 on both sides. The rainwater flowing into the side drainage channels 2 can be filtered by the filter screen 3, which can intercept larger debris such as leaves and branches in the rainwater. Then, the rainwater will be filtered by the coarse filter packing 6 in the filter box 5. Finally, the filtered rainwater can be easily diverted to the main drainage pipe 15 through the water flow channel 4. The main drainage pipe 15 will then guide the rainwater to both ends until the rainwater is discharged into the rivers on both sides of the highway. By periodically disassembling the interception box 8, the filter screen 3, and the filter well cover 10 from the highway body 1 and cleaning the drainage structure inside the highway, the unobstructed flow of the drainage mechanism can be ensured. This is the working principle of the drainage structure of the highway pavement.
