Embodiment

[0044] Example: An environmentally friendly plastic runway, such as figure 1 with figure 2 As shown, the annular foundation pit 11 is excavated on the foundation design size, and then the open both sides of the foundation pit 11 is symmetric to form a broadening groove 12, and a plurality of support components are fixed vertically in the bottom of the foundation pit 11. 3. The concrete layer 4 and the gravel layer 5 are sequentially laid in the foundation pit 11, and the support assembly 3 is distingurated from the bottom wall of the widening groove 12 on the same horizontal plane, support assembly 3 supports support plate 6. The end portion of the support plate 6 abuts the widening groove 12 and fixed, and the support plate 6 is sequentially laid, and the top surface of the plastic layer 2 is flush, and the plastic layer 2 is fixed. There is a block 8.

[0045] reference figure 2 with image 3 The support assembly 3 includes a support base 31 that is fixedly coupled to the bas...

Abstract

The invention discloses an environment-friendly plastic runway and a construction process thereof, and relates to the technical field of plastic runways. The environment-friendly plastic runway comprises a plurality of supporting assemblies vertically fixed in an annular foundation pit, a supporting plate and a plastic layer are sequentially fixed on the supporting assemblies, and the plastic layer is connected with the supporting plate in an adhesive mode. Each supporting assembly comprises a supporting base and a lifting table in threaded connection with the supporting base, and a supportingplatform is fixed to each lifting table. The plastic layer comprises a plurality of plastic modules used for being spliced to form the plastic runway. The plastic runway and the construction processhave the effects of improving the construction efficiency of the plastic runway and achieving environment-friendly construction.

Description

Technical field [0001] The present invention relates to the technical field of plastic runways, in particular, involving an environmentally friendly plastic runway and its construction processes. Background technique [0002] The plastic runway is also known as a 24-day track and field runway, which is constructed of a polyurethane prepolymer, a mixed polyether, a waste tire rubber, an EPDM rubber or PU particles, a pigment, auxiliary, a filler. The plastic runway has a good flatness, high compressive strength, proper hardness flexibility, and stable physical performance, which is conducive to the speed of athletes and technology. At present, the mixed plastic runway construction process is carried out by three-step construction method. First, the appropriate amount of rubber particles are added to the gel, and the soled shelf thickness is 8 mm. After it is solidified, the thickness is paved over. The 2 mm gel, sprinkled with red particles with artificial, recovered excess plashe...
