DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-6 This application is described in further detail.
[0034] The present application embodiment discloses an anti-skid plastic track. Figure 1 The anti-skid plastic track is laid on a concrete base 1, a drainage ditch 2 is arranged on one side of the anti-skid plastic track, and a permeable cover plate is arranged at the mouth of the drainage ditch 2.
[0035] Reference Figure 1 , along the direction away from the concrete base 1, the anti-skid plastic track includes a waterproof base coat 3, a permeable brick layer 4, a rubber particle base layer 5, an EPDM particle surface layer 6, a marking layer 7 and a waterproof strip 11. In this embodiment, the anti-skid plastic track is also referred to as a plastic track.
[0036] Reference Figure 1 , the staff cleans the surface of the concrete base 1, and the staff can use a grinder to grind the surface of the concrete base 1; along the direction away from the drainage ditch 2, the elevation of the concrete base 1 increases gradually; that is, by performing slope treatment on the concrete base 1, it is beneficial to the drainage of the plastic track.
[0037] Reference Figure 1 Then, the staff rolls the waterproof coating onto the surface of the concrete base 1, and the waterproof coating solidifies and hardens to form a waterproof base coating 3.
[0038] Reference Figure 1 The permeable brick layer 4 is formed by laying a plurality of permeable bricks, and the permeable bricks and the concrete base layer 1 can be fixedly connected by cement mortar, glue, etc. The permeable bricks have good water permeability, so that the permeable brick layer 4 has good water permeability, and the water in the plastic runway can be discharged into the drainage ditch 2 in time.
[0039] Reference Figure 1 The rubber particle bottom layer 5 is formed by mixing rubber particles (generally particles from crushed rubber tires) and glue and paving them on the permeable brick layer 4.
[0040] Reference Figure 1 The EPDM particle surface layer 6 is formed by mixing and stirring EPDM (ethylene propylene diene monomer) rubber particles and glue and laying them on the rubber particle bottom layer 5.
[0041] Reference Figure 1 Finally, the staff uses marking paint to draw the runway line on the EPDM particle surface layer 6, thereby forming a marking layer 7.
[0042] Reference Figure 1 The particles in the rubber particle bottom layer 5 and the EPDM particle surface layer 6 have a rough surface structure, which can break the water film structure outside the water body; at the same time, the rubber particle bottom layer 5 and the EPDM particle surface layer 6 have abundant gaps. Therefore, the water in the rubber particle bottom layer 5 and the EPDM particle surface layer 6 can penetrate into the permeable brick layer 4 in time.
[0043] Reference Figure 1When rain falls on the surface of the plastic track, the water in the rubber particle bottom layer 5 and the EPDM particle surface layer 6 penetrates into the permeable brick layer 4, and the permeable brick layer 4 is used to divert the water to the drainage ditch 2; thereby reducing the accumulation of water on the surface of the plastic track and improving the anti-slip performance of the plastic track in rainy days or after rain.
[0044] Reference Figure 1 and Figure 2 The water barrier 11 is fixed on the permeable brick layer 4, and the water barrier 11 is buried in the rubber particle bottom layer 5. The water barrier 11 can be built with cement mortar, and the water barrier 11 is used to separate the water body. When rainwater falls on the plastic runway, the water barrier 11 can reduce the flow of water along the permeable brick layer 4 and the EPDM particle bottom layer; the water in the plastic runway penetrates downward into the permeable brick layer 4 and is discharged, thereby improving the drainage performance of the plastic runway.
[0045] Example 2
[0046] The difference between this embodiment 2 and embodiment 1 is that:
[0047] Reference Figure 3 and Figure 4 The permeable brick layer 4 is provided with a plurality of drainage grooves 41 at intervals on one side close to the concrete base layer 1, and the drainage grooves 41 are connected to the drainage ditch 2. The permeable brick layer 4 is provided with a plurality of limiting grooves 42 on one side close to the rubber particle bottom layer 5, and the limiting grooves 42 are used to accommodate the rubber particle bottom layer 5.
[0048] Reference Figure 3 and Figure 4 , the water in the permeable brick layer 4 is drained to the drainage ditch 2 through the drainage groove 41; thereby improving the drainage efficiency of the plastic track, further reducing the occurrence of water accumulation on the surface of the plastic track, and improving the anti-skid performance of the plastic track. At the same time, a limiting groove 42 for accommodating the rubber particle bottom layer 5 is provided on the surface of the permeable brick layer 4, so that the permeable brick layer 4 and the rubber particle bottom layer 5 are interlocked, improving the connection strength between the permeable brick layer 4 and the rubber particle bottom layer 5, thereby improving the overall stability of the plastic track.
[0049] Example 3
[0050] The difference between this embodiment 3 and embodiment 1 is that:
[0051] Reference Figure 5 The plastic track also includes a plurality of absorbent cotton strips 8, which are arranged in the drainage groove 41 and are connected to the drainage ditch 2. The absorbent cotton strips 8 have good water absorption performance, thereby further improving the drainage performance of the plastic track, reducing the accumulation of water on the surface of the plastic track, and improving the anti-skid performance of the plastic track.
[0052] Example 4
[0053] The difference between this embodiment 4 and embodiment 2 is that:

A plurality of water-permeable holes 91 are provided on the side of the drainage pipe 9 away from the concrete base 1; the geotextile 10 is wrapped around the outer periphery of the drainage pipe 9. The drainage pipe 9 can reduce the occurrence of the adhesive between the permeable brick layer 4 and the concrete base 1 blocking the drainage groove 41, which is beneficial to maintaining the drainage performance of the plastic track. The geotextile 10 can reduce the occurrence of the adhesive between the permeable brick layer 4 and the concrete base 1 blocking the drainage groove 41, which is beneficial to maintaining the drainage performance of the plastic track.
