[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 3 As shown, a hybrid EPDM plastic track structure includes a runway base layer 1, a waterproof base layer 2 is laid on the upper side of the runway base layer 1, an elastic granular layer 3 is laid on the upper side of the waterproof base layer 2, an infiltration mechanism 4 is laid on the upper side of the elastic granular layer 3, and an EPDM granular layer 5 is laid on the upper side of the infiltration mechanism 4.

[0025] It should be noted that the thickness of the EPDM particle layer 5 is greater than 10 mm, and the runway line needs to be sprayed on the upper side of the EPDM particle layer 5 .

[0026] like Figure 3-Figure 5 As shown, the infiltration mechanism 4 includes a structural layer 41, the lower side of the structural layer 41 is laid on the upper side of the elastic granular layer 3, and the lower side of the EPDM granular layer 5 is laid on the upper side of the structural layer 41, and a number of evenly distributed permeable grooves 42 are opened on the upper side of the structural layer 41, and a number of evenly distributed guide tube cavities 43 are opened on the inner side of the structural layer 41 near the bottom, and the lower side of the permeable groove 42 is connected to the inner side of the guide tube cavity 43, and the inner and outer sides of the structural layer 41 are fixedly connected with a water collection platform 44, and the two ends of the guide tube cavity 43 are connected with the inner side of the water collection platform 44, and the two water collection platforms 44 are fixedly connected with a water suction pipe 46 near the left side away from the structural layer 41.

[0027] It should be noted that when the EPDM granular layer 5 is laid, the EPDM granular layer 5 will enter the inner side of the permeable groove 42 by itself, and the form is similar to the characteristics of the guide block. When it rains, the rainwater will enter the guide tube cavity 43 along the guide block to its inner side, and then enter the inner side of the water collection platform 44, and then be discharged through the pumping pipe 46.

[0028] like Figure 4As shown, the water-permeable groove 42 and the diversion tube cavity 43 are made by using a mold.

[0029] It should be noted that the molds used for the water-permeable groove 42 and the diversion tube cavity 43 are made of paper. First, a structural layer 41 is laid to fix the mold, and then laid flush with the upper surface of the mold.

[0030] like Figure 5 As shown, the water collecting platform 44 is made of cement.

[0031] It should be noted that the material of the water collecting platform 44 allows the water collecting platform 44 to be quickly formed into a shaped structure according to processing and manufacturing.

[0032] like Figure 5 As shown, the inner lower surface of the water collecting platform 44 is an inclined surface, and the left middle part of the inner lower surface of the water collecting platform 44 is the lowest point.

[0033] It should be noted that the shape of the inner lower surface of the water collecting platform 44 causes the water flowing into the inner side of the water collecting platform 44 to gather toward the water pumping pipe 46 .

[0034] like Figure 5 As shown, a plurality of evenly distributed clay pieces 45 are fixedly sleeved on the inner lower surface of the water collecting platform 44 .

[0035] It should be noted that the clay pieces 45 can be made of broken pieces of pottery basins, which can allow water to penetrate slowly and avoid residual water stains remaining on the inner side of the water collection platform 44, causing the water stains to stink and affect the air quality around the runway.

[0036] The working principle of the present invention is as follows: first, when the EPDM granular layer 5 is laid, the EPDM granular layer 5 will automatically enter the inner side of the water-permeable groove 42, which is similar to the characteristics of the guide block. When it rains, the rainwater will enter the inner side of the guide pipe cavity 43 along the guide block, and then enter the inner side of the water collection platform 44, and then be discharged through the pumping pipe 46. The rainwater passes through the guide pipe cavity 43 and enters the water collection platform 44, and then is discharged by the pumping pipe 46, so that there is no water stain on the upper side of the EPDM granular layer 5, which is convenient for work and use, and avoids the use of heating steam. The form of Teng leads to the problem of hot air retention and large energy consumption. Finally, the mold used for the water-permeable trough 42 and the guide tube cavity 43 is made of paper. First, a structural layer 41 is laid to fix the mold, and then it is laid flush with the upper surface of the mold. The material of the water collection platform 44 allows the water collection platform 44 to be processed and manufactured to quickly form a modeling structure. The characteristic structure is quickly formed through the mold, which is convenient to construct and operate. The use of paper molds avoids the environmental pollution problem caused by the use of commonly used PVC pipes without affecting the formation of characteristics.
