[0002] The plastic track has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to the athletes' speed and technology, can effectively improve sports performance and reduce the rate of falls. In some places with heavy rainfall, the efficiency of rainwater discharge is insufficient, causing the base layer of the plastic track to be soaked for a long time, resulting in cracks in the base layer and bubbling of the plastic track.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0016] A water-proof plastic runway, such as Figure 1 , 2As shown, it includes a concrete layer 1, a first hard layer 2 is fixedly installed on the concrete layer 1, a plurality of first grooves 3 are provided on the top of the concrete layer 1, a plurality of second grooves 4 are provided at the bottom of the first hard layer 2 corresponding to the first grooves 3, the first grooves 3 and the corresponding second grooves 4 can together form a cylindrical groove and a same drainage pipe 5 is fixedly installed, a through groove 6 is respectively provided on the drainage pipe 5, a plurality of first leakage holes 7 are provided on the inner wall of the second groove 4, the first leakage holes 7 are connected with the corresponding drainage pipe 5 through the through groove 6, a second hard layer 8 is movably provided on the first hard layer 2, a soft layer 9 is fixedly installed on the second hard layer 8, a plurality of second leakage holes 10 are respectively provided on the second hard layer 8 and the soft layer 9, a water seepage layer 11 is fixedly installed on the soft layer 9, a wear-resistant layer 12 is fixedly installed on the water seepage layer 11, and a water seepage layer Several seepage holes are respectively provided on 11 and the wear-resistant layer 12, and the seepage holes are interconnected with the corresponding second leakage hole 10, and are characterized in that: several plug rods 13 are fixedly installed at the bottom of the second hard layer 8, and several slots 14 are provided at the top of the first hard layer 2 corresponding to the plug rods 13, and the plug rods 13 are slidably installed in the corresponding slots 14, and the plug rods 13 are respectively connected to the first hard layer 2 through springs 15, and the springs 15 are sleeved on the outer periphery of the plug rods 13, one end of the spring 15 is fixedly connected to the outer periphery of the corresponding plug rods 13, and the other end of the spring 15 is respectively fixedly connected to the top of the first hard layer 2, and several pistons 16 are fixedly installed on the bottom of the second hard layer 8 through connecting rods, and the pistons 16 correspond to the first leakage holes 7 one by one, and the pistons 16 can be in airtight sliding contact with the corresponding first leakage holes 7. The utility model has a simple structure and ingenious design. When someone exercises on the runway, the second hard layer 8 moves up and down relative to the first hard layer 2, which can buffer the impact force generated when stepping on the second hard layer 8. At the same time, the second hard layer 8 drives the piston 16 to move up and down. When the piston 16 moves downward, it can flush out the dirt in the drain pipe 5, which can meet market demand and is suitable for promotion.When the utility model is used, in rainy weather, rainwater on the wear-resistant layer 12 enters the second leakage hole 10 through the seepage holes on the wear-resistant layer 12 and the water-permeable layer 11, and the water in the second leakage hole 10 enters the drain pipe 5 through the first leakage hole 7 and the through groove 6, and is uniformly discharged from the drain pipe 5. After long-term use, dirt is easily accumulated in the drain pipe 5, affecting the drainage effect of the drain pipe 5; when someone steps on the runway, the wear-resistant layer 12, the water-permeable layer 11, the soft layer 9 and the second hard layer 8 will move downward, thereby driving the insertion rod 13 to move downward along the corresponding slot 14, the spring 15 is compressed, and the second hard layer 8 will also drive the piston 16 to move downward along the corresponding first leakage hole 7 during the downward movement of the piston 16. During the downward movement of the piston 16, the space between the piston 16 and the dirt is reduced, the air is compressed, and the pressure gradually increases. The pressure is greater than the pressure of the outside air on the dirt, so in the process of the piston 16 moving downward, the pressure generated by the piston 16 gives a thrust to the dirt in the drain pipe 5, so that the dirt is discharged from the drain pipe 5 to prevent the drain pipe 5 from being blocked; when the person's foot is separated from the runway, under the action of the spring 15, the wear-resistant layer 12, the water-permeable layer 11, the soft layer 9 and the second hard layer 8 move upward, thereby driving the insertion rod 13 to slide upward along the corresponding slot 14, and the piston 16 moves out in the corresponding first leakage hole 7 until the person's foot steps on the runway again, and then repeats the above process to achieve the cleaning of the dirt in the drain pipe 5; at the same time, the insertion rod 13, the slot 14 and the spring 15 can achieve the effect of buffering and shock absorption; the second hard layer 8 moves up and down relative to the first hard layer 2, and the moving distance is within two millimeters, and no obvious drop will be formed, so it will not affect the runway on the second hard layer 8.

[0017] Specifically, as shown in the figure, the outer circumference of the plug rod 13 in this embodiment is respectively covered with a rubber tube 20, and the two ends of the rubber tube 20 are fixedly connected to the first hard layer 2 and the second hard layer 8 in sequence. The rubber tube 20 can prevent water or other impurities from entering the slot 14, and prevent water from being unable to be discharged in time and causing damage to the plastic track.

[0018] Specifically, as shown in the figure, the upper end of the first water leakage hole 7 in this embodiment is chamfered, and the diameter of the upper end of the first water leakage hole 7 is larger than the diameter of the lower end of the first water leakage hole 7. The chamfer of the upper end of the first water leakage hole 7 facilitates water to flow into the first water leakage hole 7.

[0019] Further, as shown in the figure, the upper end of the piston 16 of this embodiment is respectively provided with an inclined surface with a high middle and low surroundings. The inclined surface at the upper end of the piston 16 can prevent impurities from accumulating on the piston 16.

[0020] Further, as shown in the figure, the wear-resistant layer 12 of this embodiment is made of EPDM rubber, and the interior of the wear-resistant layer 12 is inlaid with anti-skid particles 50. The wear-resistant layer 12 is made of EPDM rubber to facilitate water penetration downward, and at the same time, the plastic track has good elasticity and resistance to heat and oxygen aging; the anti-skid particles make the plastic track have a good anti-skid effect.

[0021] Furthermore, as shown in the figure, the water-permeable layer 11 of this embodiment is made of resin-bonded rubber particles, the soft layer 9 is made of soft silicone, and the first hard layer 2 and the second hard layer 8 are made of hard silicone.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
