[0031] refer to Figures 1 to 2 The beach stormwater channel structure according to the embodiment of the utility model is described.

[0032] like Figure 1 to Figure 2As shown, the beach stormwater channel structure includes a stormwater channel 100, which is arranged between the beach 10 and the coastal highway 20, and extends along the boundary line between the beach 10 and the coastal highway 20; a plurality of stormwater inspection wells 200, which are arranged on the stormwater channel 100, and are evenly distributed along the extension direction of the stormwater channel 100, and the wellhead elevations of the stormwater inspection wells 200 are lower than the elevation of the beach 10; a rainwater green belt 300, which is arranged between the stormwater channel 100 and the coastal highway 20, and is arranged along the extension direction of the stormwater channel 100, and is connected to the stormwater channel 100, and is used to filter rainwater on the road surface.

[0033] like Figure 1 As shown, the beach 10 and the coastal highway 20 are arranged from left to right in sequence, and both the beach 10 and the coastal highway 20 extend in the front-to-back direction. Correspondingly, the stormwater channel 100 is located between the beach 10 and the coastal highway 20, and extends along the boundary line between the beach 10 and the coastal highway 20. The stormwater channel 100 is evenly provided with a plurality of rainwater inspection wells 200 along the extension direction, and the wellhead of each rainwater inspection well 200 is lower than the elevation of the beach 10, that is, the beach 10 covers the wellhead of the rainwater inspection well 200. A rainwater green belt 300 is arranged between the rainwater channel 100 and the coastal highway 20, and the rainwater green belt 300 extends along the boundary line between the rainwater channel 100 and the coastal highway 20. Rainwater on the coastal highway 20 flows into the rainwater green belt 300, and enters the rainwater channel 100 after being filtered by the rainwater green belt 300, thereby filtering and purifying the surface source pollution of the coastal highway 20, thereby achieving the treatment of surface source pollution of surrounding roads. At the same time, the rainwater inspection well 200 is buried below the surface of the beach 10, which not only maintains the water environment of the beach 10, but also reduces the landscape impact of the rainwater channel 100 on the beach 10.

[0034] In some specific embodiments of the present invention, a retaining wall 400 is further included. The retaining wall 400 is arranged between the stormwater channel 100 and the rainwater green belt 300. The retaining wall 400 is located at the upper end of the stormwater channel 100. The retaining wall 400 is arranged along the extension direction of the stormwater channel 100. The retaining wall 400 is used to prevent the water in the rainwater green belt 300 from directly entering the beach 10.

[0035] like Figure 1 and Figure 2As shown, the retaining wall 400 is arranged between the rainwater channel 100 and the rainwater green belt 300, and is arranged at the upper end of the rainwater channel 100 in the front-to-back direction. When the rainwater on the coastal highway 20 flows toward the beach 10, the retaining wall 400 can prevent the collected rainwater from further spreading toward the beach 10 to a certain extent. It should be noted that in order to ensure the drainage safety of the coastal highway 20, the elevation of the retaining wall 400 is lower than the elevation of the coastal highway 20. Specifically, the distance between the elevation of the retaining wall 400 and the elevation of the coastal highway 20 should be no less than 200 mm. Therefore, rainwater within the standard range can enter the rainwater channel 100 after being disposed by the rainwater green belt 300, and rainwater exceeding the disposal standard of the rainwater green belt 300 can overflow the retaining wall 400 and be discharged to the beach 10.

[0036] In some specific embodiments of the utility model, an indicator 410 is provided on the retaining wall 400, the number of the indicator 410 corresponds to the number of the rainwater inspection wells 200, and multiple indicator 410 are arranged in the extension direction of the retaining wall 400, and the indicator 410 is used to indicate the position of the rainwater inspection well 200.

[0037] like Figure 1 As shown, the retaining wall 400 is provided with indicator members 410 corresponding to the number of the rainwater inspection wells 200. In this specific embodiment, each rainwater well is provided with an indicator member 410. Of course, each rainwater well may also be provided with two or three indicator members 410.

[0038] It should be noted that the wellhead elevation of the inspection well of the stormwater channel 100 should be 500mm below the elevation of the beach 10, which is convenient for cleaning the sand surface for inspection and maintenance, and does not affect the effect of the surrounding beach 10. Furthermore, the width of the inspection well of the stormwater channel 100 is not less than 1000mm, so that personnel can enter the stormwater channel 100 from the side, and at the same time, it does not affect the use of the plank road at the upper end of the stormwater channel 100.

[0039] In some specific embodiments of the utility model, the indicator 410 is a bench 420, and the bench 420 is located on the side of the retaining wall 400 close to the beach 10. Furthermore, in order to facilitate the later maintenance, the number of the inspection wells of the rainwater channel 100 corresponds to the number of the benches 420, and the positioning is performed in combination with the landscape, that is, each bench 420 is corresponding to a rainwater inspection well 200, and is aligned with the inspection well of the rainwater channel 100, thereby serving as a mark of the rainwater inspection well 200. Specifically, the distance between two adjacent inspection wells of the rainwater channel 100 is not greater than 100m.

Specifically, the planting trough 310 is provided with a filter layer 311 and a planting layer 312 from bottom to top. The permeable blind pipe 320 is located in the filter layer 311 and is arranged close to the bottom of the planting trough 310. In this specific embodiment, the planting layer 312 is planting soil for planting, so as to form a landscape belt arranged between the beach 10 and the coastal highway 20. The filter layer 311 is gravel. After the rainwater on the road passes through the rainwater green belt 300, it infiltrates through the planting soil, is filtered by the gravel, and is collected by the permeable blind pipe 320 and discharged into the stormwater channel 100.

[0043] Specifically, the bottom elevation of the planting trough 310 is lower than the elevation of the 10th surface of the beach, that is, the distance between the bottom elevation of the rainwater green belt 300 and the elevation of the 10th surface of the beach is not less than 100 mm, the diameter of the permeable blind pipe 320 is not less than 400 mm, and the rainwater green belt 300 should meet the characteristics of flood resistance and salt resistance. The planting soil in the planting layer 312 should have good permeability to ensure that rainwater can pass through the planting layer 312 and flow into the filter layer 311.

[0044] In some specific embodiments of the present invention, a plank road assembly 500 is provided at the upper end of the stormwater channel 100, and the plank road assembly 500 includes a plate channel gap channel 540, which is located at the top of the stormwater channel 100 and is used to facilitate the flow of sand on the beach 10.

[0045] like Figure 1 As shown, a plank road assembly 500 is arranged on the rainwater channel 100, and the plank road assembly 500 is covered and arranged on the top of the rainwater channel 100, wherein the plank road assembly 500 includes imitation wood grain bricks 510 and precast concrete panels 520, which are arranged in sequence from top to bottom, and the imitation wood grain bricks 510 are arranged on the precast concrete panels 520 by mortar bonding to form a plank road for people to walk on, and a concrete pad 530 is arranged between the concrete panel and the well body outlet end, thereby, a plate channel gap channel 540 is provided between the concrete panel and the well body, so as to facilitate the flow of beach sand 10, and also reduce the thickness of the precast concrete panel 520. Specifically, the thickness of the plate channel gap channel 540 is not less than 150 mm.

[0048] Specifically, the thickness h3 of the plate channel gap channel 540 is determined according to the structural function, while ensuring that the thickness h3 of the plate channel gap channel 540 is 150 mm to facilitate the flow of surface sand.

[0049] Specifically, the elevation H1 of the manhole of the storm drain 100 is 500 mm below the elevation H0 of the beach 10, and the width B1 of the manhole of the storm drain 100 is 1000 mm. The manhole of the storm drain 100 corresponds to the bench 420, and the distance L1 between them is 100 m.
