[0032] Embodiment 1

[0033] As Figure 1 shown, the utility model provides a kind of breathable plastic track, it includes: from top to bottom sequentially includes surface layer 10, breathable layer 20, water-permeable layer 30, adhesive layer 40, base layer and ramming layer 60, wherein, the breathable layer 20 includes honeycomb structure, the honeycomb structure is made of multiple breathable units 210, each breathable unit 210 is equipped with a longitudinal air hole 211, and the cross section of each breathable unit 210 is regular pentagon or regular hexagon;Adjacent breathable unit 210 is connected by air hole 212 and communicates.

[0034] Specifically, the breathable plastic running track of this application is used in outdoor environments. The water inside the plastic running track will turn into gas when the temperature rises. In order to quickly expel the gas and avoid excessive local gas causing bulging, this application innovatively designs the breathable layer 20 as a honeycomb structure composed of multiple breathable units 210. Each breathable unit 210 can be breathable, and adjacent breathable units 210 can communicate with each other through small breathable holes 212, so that gas can flow in each breathable unit 210, avoiding excessive local gas, thereby preventing the plastic running track from bulging and solving the problem of poor breathability of plastic running tracks.

[0035] In this embodiment, the vent holes 212 are horizontally arranged relative to the longitudinal vent holes 211, and gas in one ventilated unit 210 flows through the vent holes 212 to the adjacent ventilated unit 210. Furthermore, one of the vent holes 212 is at the same height as the other vent hole 212.

[0036] Regarding the height position of the vent holes 212 on the vent unit 210, in other embodiments, one of the vent holes 212 and the other vent holes 212 are not at the same height, so that the gas in the two adjacent vent units 210 can flow in a staggered manner, avoiding mutual interference and crossflow when the gas flows.

[0037] In this embodiment, the ventilation unit 210 is formed by multiple walls 213; one or more of the walls 213 are provided with ventilation holes 212. Specifically, when the cross-section of the ventilation unit 210 is a regular hexagon, one ventilation unit 210 is connected by 6 walls 213. The 6 walls 213 can be shared with other ventilation units 210, or some walls 213 can be not shared (e.g., walls 213 near the edge of the plastic track). For example, the ventilation unit 210 located in the middle of the plastic track has a high usage rate, so the multiple walls 213 of the ventilation unit 210 at this location need to be provided with ventilation holes 212 to help the gas flow into the adjacent ventilation units 210.

[0038] In this embodiment, the breathable layer 20 is made of breathable silicone PU material, and the thickness of the breathable layer 20 is 7-10mm. Breathable silicone PU material (such as PU injection molding compound) is an elastomer and a material with good breathability. Setting the thickness of the breathable layer 20 to 7-10mm avoids the impact of excessively thick or thin breathable layers 20 on the surface of the plastic running track, ensuring the normal use of the plastic running track. Furthermore, because the breathable layer 20 uses a honeycomb structure, it enhances the support strength, allowing for a relatively thinner breathable layer 20 compared to the applicant's previous breathable plastic running track technology.

[0039] It should be noted that the permeable layer 20 described in this application is pre-formed using a mold and then laid on top of the permeable layer.

[0040] In this embodiment, the foundation layer includes a concrete layer 51 and a crushed stone layer 52, with the crushed stone layer 52 positioned below the concrete layer 51. Below the crushed stone layer 52 is a compacted layer 60, which is made of virgin soil or a mixture of soil, sand, and gravel, and the thickness of the compacted layer 60 is greater than the thickness of the crushed stone layer 52.

[0041] In this embodiment, the permeable layer 30 consists of at least one layer of plastic mesh, which is made of a mesh profile of polyethylene and polyvinyl chloride, and water permeability is achieved by utilizing the mesh structure of the permeable layer 30.

[0042] In this embodiment, the surface of the surface layer 10 is provided with a wear-resistant particle layer to greatly improve the wear resistance of the surface layer 10.

[0043] In this embodiment, the breathable layer 20 is connected to the surface layer 10 through a polyurethane layer.

[0044] Example 2

[0045] like Figure 2 As shown, this embodiment is basically the same as embodiment 1, except that in this embodiment, the vent hole 212 is inclined relative to the longitudinal vent hole 211. Specifically, the vent hole 212 is inclined from bottom to top so that the gas in the two adjacent vent units 210 can flow in a staggered manner, avoiding mutual interference when the gas flows.

[0046] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
