Description

Compound plastic course

Technical Field

The utility model relates to the field of runways, in particular to a composite plastic runway.

Background

The plastic track is also named as all-weather track for track and field sports and consists of polyurethane prepolymer, mixed polyether, waste tyre rubber, EPDM rubber grain or PU grain, pigment, assistant and stuffing. The plastic track has the characteristics of good flatness, high compressive strength, proper hardness and elasticity and stable physical performance.

At present, the foundation bed of stadium plastic course generally uses traditional cement concrete foundation bed or pitch foundation bed, traditional concrete foundation bed, do not have the energy-absorbing function as the rigidity material, in long-time use, the plastic surface course is out of shape easily, damage, form individual pit, and adopt the pitch foundation bed, the pitch material rigidity is not enough, easy deformation, the condition that caves in appears easily in the runway, adopt traditional cement concrete foundation bed or pitch foundation bed in addition, it is also outstanding on both's drainage performance, use for a long time ground basic unit easily by rainwater erosion damage planarization, thereby lead to the condition that the runway seeped water or swell.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects in the prior art, the utility model provides a composite plastic track which is provided with a ground base layer and a track layer, wherein the track layer is laid on the ground base layer, the track layer is provided with a breathable environment-friendly plastic surface layer, a semi-rigid permeable upper base layer is arranged below the breathable environment-friendly plastic surface layer, a rigid lower base layer is arranged below the semi-rigid permeable upper base layer, a waterproof layer is arranged between the rigid lower base layer and the semi-rigid permeable upper base layer, a water chute is arranged on the rigid lower base layer, and a rigid lower base layer is arranged on the ground base layer.

Further, wear-resisting surface course below is equipped with the elasticity bottom, wear-resisting surface course is formed by the spraying of polyurethane finish paint mixing EPDM environmental protection granule, the elasticity bottom is the elastic layer of PU mixed rubber granule, and wear-resisting surface course is wear-resisting, difficult fading, and the elasticity bottom provides buffering energy-absorbing effect, makes whole life increase.

Furthermore, the semi-rigid permeable upper base layer is made of permeable asphalt concrete, and has certain energy absorption capacity to contact with the elastic bottom layer while considering rigidity, so that two layers of energy absorption are provided.

Further, the rigid lower base layer is made of waterproof concrete.

Furthermore, the water chute is a circular arc-shaped groove on the rigid lower base layer.

Furthermore, the waterproof layer is formed by laying waterproof materials on the rigid lower base layer, the waterproof layer is attached to the reserved water guide groove of the rigid lower base layer and forms two layers of waterproof with the rigid lower base layer, water flow is finally concentrated in the water guide groove to be discharged, and the condition of water accumulation is avoided.

The utility model has the beneficial effects that:

the composite plastic track adopts the permeable asphalt concrete as the material of the upper base layer, and has both rigidity and energy absorption effects, water flow in the permeable asphalt concrete can directly permeate through the permeable asphalt concrete, the drainage function is excellent, the permeable asphalt concrete is contacted with the elastic bottom layer in the permeable environment-friendly plastic surface layer, and has double-layer energy absorption effect, impact received by the wear-resistant surface layer is absorbed, the track is not easy to deform and damage, the service life of the track is prolonged, and the track is not easy to sink due to the rigidity effect of the permeable asphalt concrete;

the base layer adopts waterproof concrete material and lays the waterproof layer under the rigidity, and base layer flow direction ground base layer under the unable rigidity of two-layer waterproof construction rainwater prevents that the rainwater from destroying ground base layer, and through the guiding gutter of reserving at the base layer under the rigidity again, rainwater accessible guiding gutter directly drains away.
