Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic runways, in particular to a runway system with double-layer sprayed polyurethane. Background Art
[0002] Plastic runways are generally applied to schools, stadiums and professional sports fields. Athletes can effectively reduce the impact on joints and muscles and reduce the risk of injury by using plastic runways for training and competitions. Moreover, the friction coefficient of the runway optimizes the grip and stability of running, which helps to improve speed and performance. Existing plastic runways are generally single-layer polyurethane. Although it can increase the overall performance of the plastic runway to a certain extent, the relative degree is relatively low. Therefore, a runway system with double-layer sprayed polyurethane is proposed.
[0003] Most existing plastic runways drain water through the drainage channels on both sides of the plastic runway during the rainy season. However, when the rainfall is large, the rainwater in the middle of the plastic runway cannot effectively flow into the drainage channels quickly, which may cause the rainwater to invade the interior of the plastic runway, and thus may cause the plastic runway to be damaged in advance. At the same time, existing plastic runways directly spray polyurethane on the upper end of the surface layer. However, during long-term use, the subsequent layers inside may fall off. Therefore, technical improvement is urgently needed now. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a runway system with double-layer sprayed polyurethane is proposed. The plastic runway provides a solid foundation and strong adhesion for the plastic runway through the set polyurethane bottom layer, ensuring the adhesion effect of the subsequent layers and reducing the risk of delamination and peeling. Then, through the set polyurethane surface layer, it provides additional protection for the plastic runway, enhancing the overall wear resistance and weather resistance. Finally, through the set gain mechanism, the waterproof primer can reduce the degradation of the base layer caused by moisture, improving the durability and stability of the overall runway. The antibacterial coating can effectively reduce the growth of bacteria and microorganisms on the runway surface, reducing the health risks caused by bacterial reproduction. Through the set wear-resistant layer, it can effectively withstand high-intensity use and friction, extending the service life of the runway.
[0005] To achieve the above object, the utility model provides the following technical solutions:
[0006] A double-layer spray polyurethane runway system includes an asphalt layer and a drainage mechanism. The upper surface of the asphalt layer is provided with a polyurethane bottom layer.

[0012] Further, a wire mesh is fixedly connected to the upper end of the inner wall of the circulation pipe;
[0013] Through the above technical solution, by fixedly connecting a wire mesh to the upper end of the inner wall of the circulation pipe, the wire mesh can provide partial support for the elastic sponge, avoiding the problem that the elastic sponge intrudes into the circulation pipe due to too long time.
[0014] Further, elastic sponges are fixedly connected to the upper surfaces of the circulation pipes;
[0015] Through the above technical solution, by fixedly connecting elastic sponges to the upper surfaces of the circulation pipes, some impurities can be effectively filtered out, avoiding blocking the circulation pipes.
[0016] Further, the diameter of the circulation pipe is 1.5 CM, and the diameter of the diversion pipe is 8 CM;
[0017] Through the above technical solution, the rainwater on the plastic runway can flow out better, the circulation pipes do not affect the normal use of the plastic runway, and at the same time the diversion pipes can store some rainwater.
[0018] The utility model has the following beneficial effects:
[0019] 1. A double-layer sprayed polyurethane runway system proposed by the utility model. Compared with the existing plastic runway, through the arranged circulation pipe and diversion pipe, in the rainy season, the water on the upper end of the plastic runway can enter the inside of the circulation pipe through the elastic sponge, then enter the inside of the diversion pipe through the circulation pipe, and then be stored inside the diversion pipe. When the weather is dry, the soil of the lawn in the middle of the plastic runway can absorb the water inside the diversion pipe for growth, so as to realize the reuse of rainwater. At the same time, in the rainy season, the rainwater on the plastic runway can be better drained.
[0020] 2. A double-layer sprayed polyurethane runway system proposed by the utility model. Compared with the existing plastic runway, through the arranged polyurethane bottom layer, a solid foundation and strong adhesion can be provided for the plastic runway, ensuring the adhesion effect of the subsequent layer and reducing the risk of delamination and peeling.

Moreover, through the antibacterial coating, the growth of bacteria and microorganisms on the runway surface can be effectively reduced, lowering the health risks caused by bacterial reproduction. Additionally, through the arranged wear-resistant layer, it can effectively withstand high-intensity use and friction, extending the service life of the runway. Description of the Drawings

[0034] The waterproof primer 201 is sprayed on the upper surface of the polyurethane surface layer 4. The antibacterial coating 202 is sprayed on the upper surface of the waterproof primer 201. The wear-resistant layer 203 is sprayed on the upper surface of the antibacterial coating 202, so as to better extend the overall service life of this plastic runway.
[0035] The waterproof primer 201 is made of acrylic material. The antibacterial coating 202 is an antibacterial agent. The wear-resistant layer 203 is made of EPDM particles. By making the waterproof primer 201 made of acrylic material, the antibacterial coating 202 an antibacterial agent, and the wear-resistant layer 203 made of EPDM particles, each coating can better play its role. A wire mesh 303 is fixedly connected to the upper end of the inner wall of the circulation pipe 302. By fixedly connecting the wire mesh 303 to the upper end of the inner wall of the circulation pipe 302, the wire mesh 303 can provide partial support for the elastic sponge 304, avoiding the problem that the elastic sponge 304 invades the inside of the circulation pipe 302 due to too long time.

When the weather is dry, the soil of the lawn in the middle of the plastic runway can absorb the water inside the diversion pipes 301 for growth. At the same time, during the rainy season, the rainwater on the plastic runway can be better drained. At the same time, the diversion pipes 301 can be connected to the upper end of the outer wall of the sewer pipe according to needs, so that the water inside the diversion pipes 301 can be drained, and at the same time, the problem of the water in the sewer pipe flowing back into the diversion pipes 301 is avoided. During daily use, through the provided polyurethane bottom layer 4, a solid foundation and strong adhesion can be provided for the plastic runway, ensuring the adhesion effect of the subsequent layers and reducing the risk of delamination and peeling. Then, through the provided polyurethane surface layer 6, additional protection can be provided for the plastic runway, enhancing the overall wear resistance and weather resistance. Finally, through the provided gain mechanism 2, the waterproof primer 201 can reduce the degradation of the base layer caused by moisture, improving the durability and stability of the overall runway. Then, through the antibacterial coating 202, the growth of bacteria and microorganisms on the runway surface can be effectively reduced, reducing the health risks caused by bacterial reproduction. Finally, through the provided wear-resistant layer 203, it can effectively withstand high-intensity use and friction, extending the service life of the runway.
