DETAILED DESCRIPTION

[0019] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0020] Reference Figures 1-3 The wear-resistant plastic track comprises a cement base layer 1, a waterproof layer 2 arranged on the top surface of the cement base layer 1, and a wear-resistant surface layer 3 arranged on the top surface of the waterproof layer 2. The waterproof layer 2 is arranged to facilitate the drainage of rainwater on the wear-resistant surface layer 3, so that the subsequent accumulation of rainwater on the wear-resistant surface layer 3 does not affect the track. The wear-resistant surface layer 3 is made of polyurethane material, which has high wear resistance and can effectively resist the wear caused by the running of athletes on the track. In addition, polyurethane has good elasticity and can provide effective cushioning effect to reduce the impact of exercise on joints and muscles.

[0021] In some embodiments, the waterproof layer 2 comprises an intermediate shell 4, a water inlet hole 5, a reinforcing support 6, and a drainage hole 7. The top surface of the cement base layer 1 is provided with the intermediate shell 4, and the inner bottom surface of the intermediate shell 4 is arched. A plurality of reinforcing supports 6 are arranged at equal intervals in the interior of the arched intermediate shell 4. The reinforcing supports 6 are arranged to support the interior of the intermediate shell 4 and improve the overall structural stability of the intermediate shell 4. The intermediate shell 4 serves as the middle body of the track and can provide better support for the track, so that the track will not easily deform during subsequent use. The inner bottom surface of the intermediate shell 4 is arched to facilitate the drainage of rainwater inside.

[0022] In some embodiments, the top surface of the intermediate shell 4 is provided with a plurality of water inlet holes 5, the interior of the intermediate shell 4 is fixedly provided with reinforcing supports 6, and the left and right sides of the intermediate shell 4 are respectively provided with drainage holes 7. Rainwater on the wear-resistant surface layer 3 penetrates the top surface of the intermediate shell 4 and enters the interior of the intermediate shell 4 through the plurality of water inlet holes 5. Since the inner bottom surface of the intermediate shell 4 is arched, the rainwater can be drained into the sewer through the drainage holes 7 on both sides, thereby achieving the drainage effect of the track and preventing the rainwater from accumulating on the wear-resistant surface layer 3 for a long time.

[0023] In some embodiments, the top surface of the wear-resistant surface layer 3 is provided with a plurality of wear-resistant protrusions 8 arranged at equal intervals. The wear-resistant protrusions 8 and the wear-resistant surface layer 3 are both made of polyurethane material, which can further improve the wear resistance of the track.

[0024] In some embodiments, the top surface of the intermediate shell 4 is provided with an adhesive layer I 9, the top surface of the adhesive layer I 9 is fixedly installed with a grid layer 10, the top surface of the grid layer 10 is fixedly installed with an elastic layer 11, and the top surface of the elastic layer 11 is fixed with the bottom surface of the wear-resistant surface layer 3. The adhesive layer I 9 is provided to facilitate the adhesion and fixation of the grid layer 10, so that the grid layer 10 is firmly located on the top surface of the intermediate shell 4. The adhesive layer I 9 is made of epoxy resin material. The elastic layer 11 is provided to provide good cushioning effect, thereby improving the comfort and safety of athletes. The elastic layer 11 is usually made of polyurethane, rubber or foaming material, which has excellent elasticity and shock absorption performance. By effectively dispersing impact force, the elastic layer 11 can not only reduce the impact of exercise on joints and muscles, but also increase the overall stability of the track to create a comfortable exercise environment.

[0025] In some embodiments, the bottom surface of the intermediate shell 4 is provided with an adhesive layer II 12, the bottom surface of the adhesive layer II 12 is fixedly installed with a waterproof layer 13, and the bottom surface of the waterproof layer 13 is fixed with the top surface of the cement-based layer 1. The adhesive layer II 12 is also made of epoxy resin material. In this way, the waterproof layer 13 can be adhesively fixed to the bottom of the intermediate shell 4. The waterproof layer 13 can provide waterproof effect at the bottom, so that water generated at the bottom does not move upward.

[0026] In some embodiments, the top surface of the wear-resistant surface layer 3 is provided with an acrylic coating 14. The acrylic coating 14 is usually a colored coating, which can not only add aesthetic appearance, but also provide certain wear resistance to improve the appearance of the track.

[0027] Working principle: Rainwater on the wear-resistant surface layer 3 can smoothly penetrate the elastic layer 11 and the grid layer 10, penetrate to the top surface of the intermediate shell 4, and flow into the interior of the intermediate shell 4 through the water inlet hole 5 in the top surface of the intermediate shell 4. Since the bottom surface of the intermediate shell 4 is arched, rainwater can be smoothly drained into the sewer through the drainage holes 7 on both sides, achieving efficient drainage effect. In this way, rainwater will not accumulate on the wear-resistant surface layer 3 for a long time. At the same time, the reinforcing support 6 effectively enhances the support strength of the intermediate shell 4 and improves its overall stability. The device has a simple structure and is convenient to operate. The intermediate shell 4 is located in the middle of the track and serves as a support to ensure that the track is not easily deformed during long-term use. In addition, the intermediate shell 4 can effectively drain the accumulated rainwater on the wear-resistant surface layer 3, further improving the drainage performance and avoiding long-term retention of rainwater on the track.

[0028] The above examples are only used to illustrate the technical solutions of the present application, but not to limit the same; although the present application has been described in detail with reference to the foregoing examples, it should be understood by those of ordinary skill in the art that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
