Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, specifically to a municipal sponge-type road paving structure. Background Technology

[0002] Sponge roads are an important component of sponge city construction. Their main purpose is to use specific designs and materials to give roads a certain degree of permeability and stormwater runoff control, thereby achieving ecological and environmental protection effects. The design concept of sponge roads emphasizes the natural accumulation, infiltration, and purification of rainwater, reducing the pressure of stormwater runoff on urban drainage systems, lowering the risk of urban flooding, and improving water quality. Essentially, sponge roads are roads that can absorb, store, infiltrate, and purify water like a sponge, and release the stored water for use when needed.

[0003] While sponge-type roads facilitate rainwater filtration and storage, reducing the pressure on urban drainage systems, they inevitably have shortcomings in practical use. One such shortcoming is the lack of multi-layer diversion mechanisms, which makes the road surface prone to saturation due to short-term infiltration, leading to water accumulation. Therefore, a municipal sponge-type road paving structure is proposed to address these existing problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a municipal sponge-type road paving structure, which solves the problem that the lack of a multi-layer diversion mechanism in the device leads to easy saturation of the road surface due to seepage, resulting in easy water accumulation on the road surface.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a municipal sponge-type road pavement structure, comprising a soil layer, a crushed stone cushion layer, a permeable concrete base layer, and a permeable concrete surface layer, wherein the soil layer, crushed stone cushion layer, permeable concrete base layer, and permeable concrete surface layer are distributed from bottom to top, and curb stones are provided on both sides of the top of the permeable concrete surface layer, wherein a confluence channel is formed inside the curb stone, and a number of irregularly shaped guide channels are equally spaced on the top of the permeable concrete surface layer, and a number of external drainage outlets are equally spaced on one side of the curb stone.

[0006] Preferably, a collection well is provided between the crushed stone cushion layer, the permeable concrete base layer, and the permeable concrete surface layer, and two collection wells are arranged symmetrically in the transverse direction. A coarse filter screen is installed inside the collection well. Two water storage channels are symmetrically opened inside the crushed stone cushion layer. The water storage channels on the same side are connected to the collection well. Several first discharge pipes connected to the water storage channels are installed at equal intervals on both sides of the crushed stone cushion layer, and several first discharge pipes are arranged at equal intervals.

[0007] Preferably, the crushed stone cushion layer has an infiltration water storage tank inside, and a filter hole frame is provided inside the infiltration water storage tank. Both sides of the filter hole frame are connected to a second external drain pipe, and several second external drain pipes are provided on the same side. One end of the second external drain pipe extends to the outside of the crushed stone cushion layer.

[0008] Preferably, the inner wall of the filter hole frame is fixedly connected with several reinforcing frames at equal intervals.

[0009] Preferably, a number of speed bumps are provided at equal intervals on the top of the permeable concrete surface layer.

[0010] Beneficial effects

[0011] This utility model provides a municipal sponge-type road pavement structure. Compared with existing technologies, it has the following advantages: By setting a filter frame, a second external drainage pipe, a reinforcing frame, and an infiltration and water storage tank inside the crushed stone subbase, and setting a water storage channel inside the crushed stone subbase to be used in conjunction with the manifold, the road can achieve fine filtration and collection of rainwater through the infiltration and water storage tank and coarse filtration and collection of rainwater through the water storage channel. This facilitates the rapid diversion and control of rainwater on the road surface, preventing water accumulation. Secondly, by setting a manifold and an external drainage outlet inside the curbstone, and setting a special-shaped guide channel on the top of the permeable concrete surface layer, the road surface can be quickly diverted and drained when encountering heavy rain, ensuring rapid drainage of water from the road surface.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a municipal sponge-type road pavement structure, including a soil layer 1, a crushed stone cushion layer 2, a permeable concrete base layer 3 and a permeable concrete surface layer 4, wherein the soil layer 1, the crushed stone cushion layer 2, the permeable concrete base layer 3 and the permeable concrete surface layer 4 are distributed from bottom to top, and curb stones 5 are provided on both sides of the top of the permeable concrete surface layer 4, and several speed bumps 16 are provided at equal intervals on the top of the permeable concrete surface layer 4.

[0019] Furthermore, to facilitate the diversion and control of water accumulation on the road surface, a confluence channel 6 is provided inside the curbstone 5, and several irregularly shaped diversion channels 7 are provided at equal intervals on the top of the permeable concrete surface layer 4. Several external drainage outlets 8 are provided at equal intervals on one side of the curbstone 5. As explained in detail, the irregularly shaped diversion channel 7 is formed by two symmetrical trapezoidal inclined channels connected together.

[0020] Furthermore, to facilitate the fine and coarse filtration and diversion control of rainwater, and to avoid the problem of road surface saturation due to short-term infiltration during rainwater infiltration and purification, resulting in water accumulation, a collection well 9 is provided between the crushed stone subbase 2, the permeable concrete base course 3, and the permeable concrete surface course 4. Two collection wells 9 are symmetrically arranged laterally. A coarse filter screen 10 is installed inside the collection well 9. Two water storage channels 11 are symmetrically arranged inside the crushed stone subbase 2, and the water storage channels 11 on the same side are connected to the collection well 9. On both sides of the 2, several first discharge pipes 12 connected to the water storage channel 11 are installed at equal intervals, and several first discharge pipes 12 are arranged at equal intervals. The inside of the crushed stone cushion layer 2 is provided with a seepage water storage tank 17. The inside of the seepage water storage tank 17 is provided with a filter hole frame 13. Both sides of the filter hole frame 13 are connected with second external discharge pipes 14, and several second external discharge pipes 14 are arranged on the same side. One end of the second external discharge pipe 14 extends to the outside of the crushed stone cushion layer 2. Several reinforcing frames 15 are fixedly connected at equal intervals on the inner wall of the filter hole frame 13.

[0021] When it rains, some rainwater passes through the permeable concrete surface layer 4, permeable concrete base layer 3, crushed stone cushion layer 2 and filter frame 13, and is then finely filtered and collected into the interior of the infiltration storage tank 17, and then transferred through the second external discharge pipe 14.

[0022] Water that fails to penetrate and filter in time from the road surface is coarsely filtered by the coarse filter screen 10 and collected inside the water storage channel 11, and then discharged through the first discharge pipe 12.

[0023] Secondly, the water that the coarse filter screen 10 failed to drain in time is simultaneously diverted to the inside of the confluence channel 6 through the special-shaped guide channel 7. The remaining water collected inside the confluence channel 6 is discharged to both sides of the road through the external discharge outlet 8.
