Construction technology of breathable plastic runway

Abstract

The invention discloses a construction technology of a breathable plastic runway, and belongs to the field of plastic runways, the construction technology of the breathable plastic runway comprises the following steps: S1, before the runway is laid, the ground needing to be constructed needs to be integrally cleaned, after cleaning is completed, cement concrete is laid on the ground, acid pickling is performed with 5%-8% diluted hydrochloric acid, then washing is performed with clean water, after the rough, the convex part or the concave part of the surface is polished and flattened, an air guide chain is added between the primer and the black rubber particle layer to guide water vapor at the bottom to the outside, so that the purpose of ventilation is achieved, and the water vapor generated at the bottom enters the ventilation cavity through the air inlet pipe and is guided into the drainage ditch through an exhaust pipe; the accumulation of water vapor is reduced, thereby the bubbling problem is effectively reduced, the extrusion cavity is compressed by utilizing the downward pressure of treading of a person, so that the water vapor discharge speed is accelerated, the water at the bottom is absorbed by utilizing the high water absorption of the capillary tube, the generation of the water vapor is reduced, and the bubbling problem of the runway is further reduced.

Description

technical field [0001] The invention relates to the field of plastic runways, and more specifically, relates to a construction technique of a breathable plastic runway. Background technique [0002] The good elasticity and anti-slip properties of plastic can effectively protect the leg joints of athletes, prevent accidental injuries, reduce physical exertion, and improve competition performance; plastic can moderately absorb the impact of feet and reduce sports injuries. Appropriate; the plastic field can also prevent sports injuries caused by falls. [0003] Plastic track, also known as all-weather sports track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance,...

Problems solved by technology

[0004] Blistering is one of the common problems of plastic runways. The reason for foaming is that there is water seepage at the bottom, and water vapor is generated under the sun, which causes blistering on the surface layer. At present, most of the ways to solve the problem of foaming are to use porous materials for laying , although the problem of ventilation has been solved, the production cost of porous materials is high, coupled with the uneven laying process, it is easy to cause water seepage on the runway, not only does not solve the problem of ventilation, but aggravates the foaming
