DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the application will be described clearly and completely below in conjunction with the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all the other embodiments obtained by the person skilled in the art without creative labor are involved in the scope of the application.

[0024] As Figures 1-6As shown, the embodiment discloses a road surface water passing device based on the concept of superficial flow, comprising a plurality of drainage grooves 2 arranged on the surface of the outer road paving layer 1, wherein the road paving layer 1 can also be paved with pervious concrete or pervious brick, having good bearing capacity and water permeability, and a plurality of drainage grooves 2 are distributed in parallel on the road paving layer 1, and are arranged through the width direction of the road paving layer 1.

[0025] As shown in the drawings, Figures 2-3 The parallel drainage grooves 2 arranged on the road paving layer 1 have trapezoidal cross sections and inner guide surfaces designed so that rainwater that has penetrated into the grooves is uniformly dispersed under the action of gravity along the designed slope and flows to the drainage outlets 4 at both ends, rather than being concentrated in a local area. This superficial flow of water layer greatly reduces the impact force generated by rainwater scouring the road surface due to its low flow speed and shallow flow depth, avoiding the phenomenon of deep water pits caused by concentrated water flow, thereby effectively ensuring the safety of road driving and pedestrians; at the same time, when the rainfall is small, the water flow on the ground can enter the drainage grooves 2, thereby reducing the height of the water on the road surface, avoiding the formation of deep water pits on the road surface, and allowing the slow-flowing water to penetrate to the underside of the road surface.

[0026] In addition, as shown in the drawings, Figure 2 The road paving layer 1 is also paved with a water permeable plate 3 above the drainage grooves 2, which is made of water permeable brick or water permeable concrete and has a plurality of microporous structures that allow rainwater to directly penetrate into the drainage grooves 2; then the water flow is discharged through the drainage outlets 4 at both ends of the drainage grooves 2 into the drainage mechanism 5, and the drainage mechanism 5 guides the water flow into the external drainage system to achieve rainwater discharge.

[0027] And as shown in the drawings, Figure 2 , 5 ​As shown, the drainage mechanism 5 includes a permeable water storage tank 51 connected to the drainage port 4, and the permeable water storage tank 51 is provided with an overflow port 52 located below the drainage port 4, and the permeable water storage tank 51 and the overflow port 52 are connected with the drainage system. Specifically, the permeable water storage tank 51 is composed of permeable bricks, and the water flow on the road surface enters the drainage groove 2 after passing through the permeable water plate 3, and is first guided into the permeable water storage tank 51. The permeable water storage tank 51 is paved with permeable bricks, and the outer surface is in communication with the underground soil or water storage layer, so that the rainwater entering the water storage tank can be released to the underground soil or water storage layer in a slow permeation manner, reducing the pressure of the urban drainage pipe network, and realizing the reuse of water flow; at the same time, the permeable water storage tank 51 can also buffer the water flow, avoiding the direct entry of large flow water into the drainage pipe network, causing excessive pressure of the drainage system; and the setting of the overflow port 52 can quickly guide the excess rainwater to enter the external drainage pipe network through the drainage pipe 53 when the rainfall exceeds the storage capacity of the water storage tank, thereby ensuring that the entire system can still operate efficiently under strong rainfall conditions.

[0028] As shown in Figure 3 , a shunt hole 6 is arranged between adjacent drainage grooves 2, and the shunt hole 6 is used to connect adjacent drainage grooves 2 with each other, so as to ensure that the water flow between the grooves can communicate with each other, thereby balancing the drainage pressure of the entire road surface and preventing the local drainage groove 2 from being overloaded to cause poor drainage.

[0029] Further, as shown in Figures 4-6 , a plurality of water seepage holes 7 are formed in the water permeable plate 3 and are in communication with the drainage groove 2, and a control valve 8 is arranged at the water seepage hole 7. The control valve 8 is used to control the opening and closing of the water seepage hole 7. When the accumulated water on the road paving layer 1 reaches a set height, the control valve 8 opens the water seepage hole 7, so that the water flows into the drainage groove 2 through the water seepage hole 7. Specifically, the control valve 8 includes a valve head 81 slidingly arranged in the water seepage hole 7, and a return spring 82 abuts between the valve head 81 and the inner wall of the water seepage hole 7. The return spring 82 is used to drive the valve head 81 to seal the water seepage hole 7.

[0030] The design of the water seepage hole 7 and the control valve 8 on the water permeable plate 3 can automatically control the opening and closing of the water seepage hole 7 according to the height of the accumulated water on the road. When the rainfall is large and the road surface appears to be accumulated with water, the water seepage hole 7 arranged on the water permeable plate 3 is embedded with the control valve 8 with the return spring 82. The control valve 8 can be automatically opened under the action of water pressure, rapidly guiding the accumulated water into the drainage groove 2, and can be sealed by the spring reset after the water level drops, thereby intelligently controlling the rainwater discharge process and avoiding the situation that the water permeable plate 3 cannot quickly discharge the accumulated water on the road surface due to excessive rainfall.

[0031] Further, the water seepage hole 7 is provided with a counterbore 11 at one end of the water permeable plate 3, the counterbore 11 is provided with a shielding cover 9 above the water seepage hole 7, the shielding cover 9 has an outer diameter larger than the inner diameter of the water seepage hole 7, a filter sheet 10 with filter holes is formed between the shielding cover 9 and the inner wall of the counterbore 11, the shielding cover 9 and the inner wall of the counterbore 11 form a mesh filter sheet 10, which effectively prevents road debris from entering the drainage system, thereby reducing the risk of blockage and reducing the cost of later maintenance; meanwhile, the shielding cover 9 also avoids the direct effect of the pressure on the road on the control valve 8, thereby preventing the control valve 8 from being damaged and prolonging the service life of the control valve 8.

[0032] Working principle: when it rains, the rainwater first seeps into the road paving layer 1 paved with water permeable concrete or water permeable bricks, and then enters the entire drainage system through the parallel drainage grooves 2 arranged on the road surface; the drainage grooves 2 have a trapezoidal cross section and an inner guide surface design, so that once the rainwater enters the groove, it is uniformly dispersed along the designed slope under the action of gravity, and slowly flows to the drainage outlets 4 at both ends, without concentrating in a local area to form a deep pit. At the same time, the micro-porous structure arranged on the water permeable plate 3 covering the drainage grooves 2 and the water seepage hole 7 arranged in the water permeable plate 3 work together, when the road surface water reaches a certain height, the control valve 8 embedded with a return spring 82 will be automatically opened under the action of water pressure, accelerating the water to enter the drainage groove 2; the water flow is then introduced into the permeable water storage tank 51 connected to the drainage groove 2 through the drainage outlets 4 at both ends of the drainage groove 2. The permeable water storage tank 51 is paved with water permeable bricks, and its outer surface is in communication with the underground soil or water storage layer, so it can gradually release the rainwater to the underground in a slow permeation manner, which not only reduces the pressure on the urban drainage pipe network, but also realizes the reuse of rainwater resources; when the rainfall is too heavy, the excess water flow is quickly discharged into the external drainage system through the overflow port 52 arranged below the water storage tank, ensuring the safe and stable operation of the entire system. The adjacent drainage grooves 2 in the system are connected through the shunt holes 6 to balance the water flow pressure between the regions and prevent local overload; in addition, the shielding cover 9 and the mesh filter sheet 10 arranged in the counterbore 11 on one side of the water seepage hole 7 can effectively intercept road debris, reduce the risk of blockage and reduce the cost of later maintenance. In summary, the present application adopts the concept of shallow flow, so that the rainwater forms a low-energy, uniformly dispersed shallow flow on the road surface, which not only greatly reduces the scouring effect of the water flow on the road surface and prevents the formation of deep pits, but also ensures that the rainwater can be discharged into the underground drainage system in a timely and efficient manner, realizing intelligent control and rational utilization of rainfall.

[0033] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
