Description

Technical Field

[0001] The utility model relates to the field of concrete pavement, in particular to an ecological breathable concrete pavement. Background Art

[0002] Ecological concrete pavement refers to a pavement with cement concrete slabs as the surface layer. It refers to a pavement structure composed of cement concrete slabs as the surface layer, with a base layer and a cushion layer underneath. It is usually a porous, lightweight, new type of environmentally friendly ground paving material mixed in a certain proportion with small stones, high-grade concrete, mixed with permeable admixtures, water, color enhancers and stabilizers. It has good air permeability and water permeability, allows rainwater to flow into the ground, effectively replenishes groundwater, and makes the city's environmental construction more natural and harmonious.

[0003] Most of the existing ecological breathable concrete pavements only rely on the gaps between material aggregates to achieve water permeability and air permeability. Although good water permeability and air permeability effects can be achieved, after the ecological breathable concrete pavement has been used for a long time, the gaps therein are very likely to become clogged, which can easily affect the overall air permeability and water permeability of the ecological breathable concrete pavement, resulting in the good use effect of the ecological breathable concrete pavement still not being ideal for a long time. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an ecological breathable concrete pavement with double air permeable passages to ensure a good use effect for a long time in view of the current status of the prior art.

[0005] The utility model is achieved through the following technical scheme: the utility model proposes an ecological breathable concrete pavement, including a rammed soil layer and breathable concrete, a crushed stone cushion layer is laid on the upper end of the rammed soil layer, breathable concrete is poured on the upper end of the crushed stone cushion layer, the breathable concrete includes a breathable concrete base layer located on the upper end of the crushed stone cushion layer and a breathable concrete surface layer located on the upper end of the breathable concrete base layer, leakage holes are opened on the upper end surface of the breathable concrete surface layer, there are multiple leakage holes and they are evenly distributed, and drainage grooves are opened on the upper end surface of the breathable concrete surface layer between the leakage holes.

[0006] By adopting the above technical solution, the rammed earth layer and the crushed stone cushion layer can provide a stable bearing foundation for the breathable concrete, thereby ensuring the structural stability of the breathable concrete.

[0007] Furthermore, the air permeability of the breathable concrete surface layer is greater than that of the breathable concrete base layer.

[0008] By adopting the above technical solution, the breathable concrete has good air and water permeability effects.

[0009] Furthermore, the drainage groove has a certain slope, and is higher in the middle, while both ends adjacent to the leakage holes are in a downhill position.

[0010] By adopting the above technical solution, the drainage effect of the drainage groove on the water is ensured.

[0011] Furthermore, the water leakage holes are of a staggered distribution structure, and the hole diameter of the water leakage holes is 3-6 cm.

[0012] By adopting the above technical solution, specific specifications and dimensions of the water leakage hole are proposed.

[0013] Furthermore, the drainage grooves are distributed in a staggered manner in a mesh, and the width of the grooves of the drainage grooves is 1-2 cm.

[0014] By adopting the above technical solution, specific specifications and dimensions of the drainage groove are proposed.

[0015] Furthermore, a plurality of diversion bottom holes are opened in the middle of the bottom end of the leakage hole, and the diversion bottom holes are evenly distributed. A plurality of diversion side holes are opened on the side walls of the bottom end of the leakage hole, and the diversion side holes are evenly distributed. The diversion bottom hole and the diversion side holes are hole structures that expand outward to drain.

[0016] By adopting the above technical solution, the drainage and ventilation effect of the water leakage hole is diffused, so that the drainage and ventilation range of the water leakage hole can be wider.

[0017] Furthermore, the diversion bottom holes and the diversion side holes all penetrate the air-permeable concrete surface layer, and the lower end surface of the air-permeable concrete surface layer is formed with evenly distributed water-permeable micropores.

[0018] By adopting the above technical solution, the diversion bottom hole and the diversion side hole have excellent air and water permeability effects.

[0019] Furthermore, a filter cup can be placed in the water leakage hole, the filter cup is made of a steel structure material, and the upper end surface of the filter cup is not higher than the bottom end surface of the drainage groove.

[0020] By adopting the above technical solution, the filter cup can filter the water entering the water leakage hole to avoid clogging the diversion bottom hole and the diversion side hole.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The utility model provides a group of auxiliary water-permeable and air-permeable structures composed of a breathable concrete surface layer, leakage holes, drainage grooves, diversion bottom holes, diversion side holes, filter cups, and water-permeable micropores, so that the ecological breathable concrete pavement can be formed with additional air-permeable and water-permeable holes on the basis of the air-permeable and water-permeable material aggregates, and the hole structure is a diffusion-like structure, so that the ecological breathable concrete pavement can still have a relatively wide area of ​​air-permeable and water-permeable effect after the aggregate gaps are blocked after long-term use, avoiding excessive scouring of the foundation soil by a single vertical permeable hole, thereby ensuring the good use effect of the ecological breathable concrete pavement for a long time.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figure 1-Figure 3As shown, an ecological breathable concrete pavement in this embodiment includes a rammed earth layer 1 and breathable concrete 3, a crushed stone cushion layer 2 is laid on the upper end of the rammed earth layer 1, and breathable concrete 3 is poured on the upper end of the crushed stone cushion layer 2, and the breathable concrete 3 includes a breathable concrete base layer 302 located at the upper end of the crushed stone cushion layer 2 and a breathable concrete surface layer 301 located at the upper end of the breathable concrete base layer 302, and the upper end surface of the breathable concrete surface layer 301 is provided with leakage holes 4, and there are multiple leakage holes 4 and they are evenly distributed, and the upper end surface of the breathable concrete surface layer 301 is provided with drainage grooves 5 between the leakage holes 4, wherein the crushed stone cushion layer 2 can further disperse the water that passes through the breathable concrete surface layer 301 and the breathable concrete base layer 302, so as to avoid excessive scouring of the rammed earth layer 1.

[0033] like Figure 1-Figure 3 As shown, the air permeability of the breathable concrete surface layer 301 is greater than that of the breathable concrete base layer 302, the drainage groove 5 has a certain slope, and is high in the middle, and both ends adjacent to the leakage holes 4 are in a downhill situation, ensuring the drainage effect of the drainage groove 5 on the water, the leakage holes 4 are a staggered distribution structure, the hole diameter of the leakage holes 4 is 3-6cm, the drainage grooves 5 are staggeredly distributed in a mesh, and the notch width of the drainage grooves 5 is 1-2cm, which can ensure that the leakage holes 4 and the drainage grooves 5 have excellent effects.

[0034] like Figure 4-Figure 5 As shown, a plurality of diversion bottom holes 6 are provided in the middle of the bottom end of the leakage hole 4, and the diversion bottom holes 6 are evenly distributed. A plurality of diversion side holes 7 are provided on the side walls of the bottom end of the leakage hole 4, and the diversion side holes 7 are evenly distributed. Both the diversion bottom hole 6 and the diversion side holes 7 are hole structures that expand outward for drainage, thereby ensuring the air permeability and water permeability of the diversion bottom hole 6 and the diversion side holes 7. Both the diversion bottom hole 6 and the diversion side holes 7 penetrate the breathable concrete surface layer 301, and the lower end surface of the breathable concrete surface layer 301 is formed with evenly distributed water-permeable micropores 8, thereby making the air permeability and water permeability of the diversion bottom hole 6 and the diversion side holes 7 more extensive and uniform.

[0035] like Figure 6 As shown, a filter cup 9 can be placed in the leakage hole 4. The filter cup 9 is made of a steel structure, and the upper end surface of the filter cup 9 is not higher than the bottom end surface of the drainage groove 5. The filter cup 9 can provide a protective effect for the leakage hole 4, and the filter cup 9 can be disassembled, replaced, cleaned, and maintained.

[0036] The specific implementation process of this embodiment is as follows: the gap between the material aggregates of the breathable concrete surface layer 301 and the breathable concrete base layer 302 is relatively large, so that the breathable concrete surface layer 301 and the breathable concrete base layer 302 have the effect of air permeability and water permeability in terms of materials, and the crushed stone cushion layer 2 can further dilute the water that passes through the breathable concrete surface layer 301 and the breathable concrete base layer 302 to avoid water flow scouring the plain soil rammed layer 1. After the breathable concrete surface layer 301 has been used for a long time, the gap between the material aggregates will be blocked by the fine particles accumulated for a long time, causing the breathable concrete surface layer The overall air permeability and water permeability of 301 is poor, while the water and air on the breathable concrete surface layer 301 can enter the leakage hole 4 through the drainage groove 5, and then enter the breathable concrete base layer 302 through the diversion bottom hole 6 and the diversion side hole 7 respectively, and then flow into the plain soil rammed layer 1 through the gravel cushion layer 2 and enter the underground soil. Since the holes of the diversion bottom hole 6 and the diversion side hole 7 are diffused, the breathable concrete surface layer 301 can still have a relatively wide air permeability and water permeability effect after the gap between the material aggregate is blocked, thereby ensuring the good use effect and longevity of the ecological breathable concrete pavement.
