Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen transportation, in particular to a plastic runway which is easy to maintain. Background Art

[0002] The plastic track, also known as the track and field sports track, is generally laid on an asphalt or cement foundation. The surface flatness of the foundation is required to be high to ensure that the thickness of the plastic surface layer is consistent and the elasticity is uniform. After laying, it usually requires a period of maintenance before it can be used. It is widely used in kindergartens, schools, stadiums, training halls, parks, communities and other activity venues. It is internationally recognized as the best all-weather outdoor sports field floor material.

[0003] During the use of the plastic track, it will be worn due to the friction between the soles of the athletes and its surface. If the worn position needs to be repaired, the entire plastic track needs to be closed to prevent the repair material from being damaged again by the athletes during the drying and curing process. This will undoubtedly delay the athletes' training and affect their performance. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A plastic track that is easy to maintain, comprising a splicing block 5, wherein the splicing block 5 is divided into a rubber layer 1, a buffer layer 2 and a hydrophobic layer 3 from top to bottom, the head ends of the rubber layer 1 and the buffer layer 2 are fixedly connected with a connecting block 4, the tail ends of the rubber layer 1 and the buffer layer 2 are provided with a connecting groove 401, the connecting block 4 and the connecting groove 401 are convex-shaped, and the size and thickness are adapted, there are multiple splicing blocks 5, the splicing block 5 at the head end is not provided with a connecting block 4, and the splicing block 5 at the tail end is not provided with a connecting groove 401.

[0020] By adopting the above design, when laying the plastic track, the grooves adapted to the splicing blocks 5 can be dug according to the length of the track to be laid, and then the corresponding number of splicing blocks 5 can be transported to the position, and the laying operation can be carried out by docking the connecting blocks 4 and the connecting grooves 401. By laying in the above manner, when the plastic track is damaged, the corresponding splicing blocks 5 can be removed according to the damaged position and replaced with spare splicing blocks 5, so that the subsequent maintenance operations are more convenient, and the dismantled plastic track can be separately maintained and repaired.

[0021] Specifically, refer to Figure 1 and Figure 2 By fixing the connecting pin 402 on the bottom surface of the connecting block 4, a connecting slot 403 adapted to the connecting pin 402 is opened on the top surface of the hydrophobic layer 3. In the connected state, the connecting pin 402 is inserted into the connecting slot 403, so that the connection relationship between the connecting block 4 and the connecting slot 401 is more closely connected, and the splicing block 5 is less likely to loosen after the connection is completed. By symmetrically arranging the two connecting blocks 4 and the connecting slot 401 along the left and right central axes of the rubber layer 1, there are more connecting points and the force is more uniform, so that the stress is not concentrated, and the splicing of the splicing block 5 is more stable.

[0022] Further, refer to Figure 3 The hydrophobic layer 3 is composed of a high-density polyethylene film, which has good waterproof properties and is tilted. The angle can be freely selected between 3° and 8° depending on the area. The lowest point of the hydrophobic layer 3 is connected to a drainage ditch, so that when rainwater penetrates into the hydrophobic layer 3, due to the tilted setting of the hydrophobic layer 3, the rainwater will be guided to the drainage ditch. The hydrophobic layer 3 can also prevent groundwater from penetrating into the buffer layer 2 from below, thereby soaking the bottom surface of the rubber layer 1 and causing bubbling.

[0023] The buffer layer 2 is composed of a mixture of rubber particles and polyurethane. The rubber particles and the polyurethane mixture have a shock-absorbing effect, which can reduce the impact force on the joints and muscles of athletes during running and reduce the risk of sports injuries. The bottom surface of the buffer layer 2 is provided with a plurality of support columns 202 from low to high along the inclination direction of the hydrophobic layer 3, and the top surface thereof is provided with a plurality of water transfer holes 201 at equal intervals in a linear array, so that when rainwater penetrates into the top surface of the buffer layer 2, it will enter the top surface of the hydrophobic layer 3 through the water transfer holes 201, and because of the provision of the support columns 202, the bottom surface of the buffer layer 2 is no longer in contact with the top surface of the hydrophobic layer 3, so that the drainage effect of the hydrophobic layer 3 is better.

[0024] The rubber layer 1 is composed of multiple materials such as polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles. The rubber layer 1 composed of the mixed materials has multiple tiny holes. When it rains, rainwater can enter the buffer layer 2 along the micropores from the top surface of the rubber layer 1, and then enter the hydrophobic layer 3 for discharge, and its top surface is provided with anti-slip grooves 101.

[0025] Working principle:

[0026] When laying the plastic track, grooves adapted to the splicing blocks 5 can be dug according to the length of the track to be laid, and then the corresponding number of splicing blocks 5 can be transported to the location, and the laying operation can be carried out by docking the connecting blocks 4 and the connecting grooves 401. By laying in the above manner, when the plastic track is damaged, the corresponding splicing blocks 5 can be removed according to the damaged position and replaced with spare splicing blocks 5, thereby making the subsequent maintenance operations more convenient, and the dismantled plastic track can be separately maintained and repaired.

[0027] During use, if the plastic track is worn or has other problems, the front and rear connections of the splicing block 5 at that location can be separated from the whole according to the location of the damaged plastic track, thereby separating the damaged splicing block 5 from the whole. The spare splicing block 5 is then transported to that location to replace the damaged splicing block 5, and the connecting block 4 and the connecting groove 401 on it are docked with the overall plastic track, so that the damaged plastic track can be replaced simply and quickly, making the later maintenance work of the plastic track more convenient.

[0028] When it rains, because the rubber layer 1 has multiple micropores, rainwater on the top surface will penetrate through the micropores, making the rainwater contact with the buffer layer 2, and then fall into the hydrophobic layer 3 from the water transfer hole 201, and flow into the sewer pipe on the side along the inclination angle of the hydrophobic layer 3, so that no water will accumulate on the surface and below the rubber layer 1, thereby preventing the rubber layer 1 from being soaked in water and bubbling, making the subsequent maintenance work of the staff more convenient.
