Seamless prefabricated plastic runway system and construction method thereof

Abstract

According to the seamless prefabricated plastic runway system and the construction method thereof, the base layer serves as the bottom face and is provided with the prime coat bonding layer, the prefabricated buffer layer and the anti-skid face layer from bottom to top in sequence, the buffer layer is prefabricated through a polyurethane material in a factory, and the technology of on-site construction of the face layer is combined; the problems that a prefabricated buffer layer is prone to cracking, poor in impact absorption performance, long in polyurethane construction period and the like are effectively solved, the uneven particle surface is adopted in the prefabricated buffer layer, and the bonding firmness between layers is greatly improved; white polyurethane foaming particles capable of improving the impact absorption capacity and rebound resilience of the system are added into the prefabricated buffer layer, impact on the feet in the running process is effectively absorbed, good prefabricated performance is provided for the feet, and a large amount of energy can be fed back through the high rebound effect of materials. And moreover, the environment-friendly sports shoe is more environment-friendly, better in elasticity, better in sports performance, long in service life and higher in comprehensive cost performance.

Description

technical field [0001] The invention relates to the field of road construction and pavement, in particular to a seamless prefabricated plastic track system applied to various sports centers and stadiums and a matching construction method thereof. Background technique [0002] The prefabricated plastic track is a kind of sports ground or track. This track usually has a flat structure, including a friction surface layer, a shock-absorbing bottom layer and an adhesive layer arranged between the shock-absorbing bottom layer and the foundation. The prefabricated plastic track is reliable in use. Maintenance hassles are reduced and service life is generally longer. [0003] The traditional prefabricated runway under the existing technology is usually made of rubber, which is about 13mm thick before leaving the factory, and then directly spliced ​​on site, and the gap at the splicing is covered by drawing white lines. After a long period of feedback from users, it is known that be...

AI Technical Summary

Problems solved by technology

After a long period of user feedback, it is known that because the traditional prefabricated runway is extruded from rubber raw materials after vulcanization, it is easily affected by temperature, thermal expansion and contraction will be severe, and it is very easy to cause cracks at the seams , and then warp

The prefabricated rubber track produced by the traditional vulcanization process is generally hard, especially after a period of use, its performance will become worse and worse with aging, and it will become harder and harder, and its ability to absorb impact will also become more and more Poor, unable to meet the requirements of protection during sports. In addition, with the serious aging phenomenon, cracks and edge warping will generally appear

[0004] There is also a polyurethane plastic runway in the prior art, all of which are paved, poured or sprayed on the construction site. The aging performance is relatively good, and the sports performance is not easy to lose. If there is a lot of rain, the construction period will be delayed for a long time, and the on-site construction, due to the level of operators, cannot control the thickness of the runway very well, and the impermeable plastic runway can easily cause water accumulation in some areas , and due to the uneven thickness, the physical properties are different, and the comfort of the foot will be very poor.

At the same time, during the construction of the polyurethane runway, each process is basically leveled with a paver or liquid self-leveling, and then the next process is carried out after curing, especially for the micro-foamed full-plastic or For mixed runways, if the bonding strength between layers is not good, it is easy to cause delamination, the performance of the runway is affected, the life is greatly reduced, and maintenance is difficult
