Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer toFigures 1-3 , the present utility model provides a technical solution: a sunken drainage structure for a road green belt, including a highway road surface 1, on which there is a green belt 7. The interior of the green belt 7 is filled with an isolation layer 13, and the isolation layer 13 is located on top of the second filter layer 15; on top of the isolation layer 13 is provided a planting soil 12, and on top of the planting soil 12 is provided a permeable layer 11; the material of the permeable layer 11 is vermiculite soil, and the material of the isolation layer 13 is crushed stones; this structure can improve the drainage performance by setting the permeable layer 11 to avoid water accumulation inside the green belt 7; the isolation layer 13 can isolate the planting soil 12 from the cover plate 14 to prevent the cover plate 14 from being blocked; at the bottom of the green belt 7 is provided a soakaway well 4, the interior of the soakaway well 4 is filled with a coarse sand layer 5, and on top of the coarse sand layer 5 is provided a fine sand layer 3; this structure can filter impurities and mud in rainwater by setting the coarse sand layer 5 and the fine sand layer 3; at the bottom of the soakaway well 4 is provided a water outlet pipe 10, the water outlet pipe 10 is of an inclined structure, and a first filter layer 2 is provided at both the top end of the water outlet pipe 10 and the top of the fine sand layer 3; the first filter layer 2 of this structure is non-woven fabric, and it can intercept and reduce particulate impurities to prevent the water outlet pipe 10 from being blocked; during use, one end of the water outlet pipe 10 can be connected to a municipal fountain pipeline, can also be used for the water supply of a public toilet, or can be used for the irrigation of green vegetation 6 to improve the utilization of rainwater; at the top end of the soakaway well 4 is provided a cover plate 14, the cover plate 14 is of a mesh structure, on top of the cover plate 14 is provided a second filter layer 15, on top of the second filter layer 15 is provided a planting soil 12, and green vegetation 6 is planted inside the planting soil 12. Drainage grooves 9 are provided on both sides of the green belt 7, convex blocks are provided on the inner side of the drainage grooves 9, and grid plates 8 are provided on the convex blocks; this structure can intercept leaves, impurities, etc. on the road surface through the grid plates 8 to reduce the occurrence of blockage of the drainage grooves 9; the drainage grooves 9 and the grid plates 8 are connected by concrete; on one side of the drainage grooves 9 is provided a drainage channel 18, one end of the drainage channel 18 is communicated with the soakaway well 4, one end of the drainage channel 18 is rotatably connected with a baffle 17, and a stop bar 16 is fixedly connected to the inner wall of the drainage channel 18, and the baffle 17 is located outside the stop bar 16; by setting the stop bar 16, a one-way interception effect can be achieved on the baffle 17, so that the baffle 17 can only rotate into the soakaway well 4 and cannot rotate into the drainage channel 18, thereby preventing backflow to the top of the highway road surface 1 through the drainage channel 18 when the water in the soakaway well 4 is full.

[0022] Working principle: When using this sunken drainage structure for road green belts, first, rainwater successively passes through the permeable layer 11, planting soil 12, isolation layer 13, second filter layer 15, and cover plate 14 and enters the infiltration well 4. After the rainwater enters the infiltration well 4, it successively passes through the first filter layer 2, fine sand layer 3, infiltration well 4, and coarse sand layer 5, and after filtration, it is discharged from the outlet pipe 10 for reuse. The surplus water on the top of the road surface 1 passes through the grid plate 8 and enters the drainage groove 9. Subsequently, the rainwater enters the drainage channel 18 and pushes the baffle 17 to rotate and open, allowing the rainwater to enter the infiltration well 4. When the water level in the infiltration well 4 is higher than the baffle 17, the rainwater exerts pressure on the surface of the baffle 17, causing the baffle 17 to close and preventing the rainwater from infiltrating back through the drainage channel 18.
