Detailed explanation of the construction process of breathable plastic runway.
Breathable plastic runway is a kind of ground material widely used in various sports venues, and its construction process needs to be strictly controlled to ensure the quality and service life of the runway. The following is a detailed explanation of the construction process of the breathable plastic runway:
1. Preparation for entering and placing the construction site.
Before entering the construction site, the following preparations need to be made:
1.Prepare the necessary construction tools and materials such as adhesive tape, quartz clocks, rulers, stone pens, paints, wire boxes, etc.
2.Inspect the raw materials and synthetic materials entering the site to ensure that their quality is up to standard. Including environmental protection rubber particles, red rubber particles, green rubber particles, component A, component B, catalysts, thinners, barrels, etc., must be marked with the type and number.
3.Choose a reasonable location of the mixing plant, not only to facilitate the construction and short-distance transportation of raw materials, but also not to affect the construction, the ground needs to be paved with iron plates or plastic sheets to prevent pollution of the ground.
Second, the foundation of leveling.
Before laying a breathable plastic runway, the foundation needs to be leveled
1.Measure in sections with a three-meter ruler, measure the arc area and curve of the football field and the straight track longitudinally, and use a stone pen to indicate the depression, and the width of each measurement cannot be greater than 4 meters.
2.Use the prepared environmentally friendly rubber particles, use a straight ruler and a heated trowel to level the depression.
Third, the paving of the bottom layer.
After the foundation is leveled, the paving of the bottom layer is carried out
1.The whole site was cleaned, and the eyes on the gutter cover were sealed with a cut sand cloth and adhesive.
2.The paver is adjusted normally, the height of the trowel plate to the foundation ground is adjusted as required, and the paving starts longitudinally from the football field, and then the runway.
3.Add 20% adhesive with environmentally friendly rubber particles, add an appropriate amount of catalyst according to the temperature, and stir for 3 minutes through a blender.
4.The professional controls the keyboard and handles the seam with a trowel in one hand. The operation is correct, no leakage, not too high, no lack of material depression. The two people control the material, so that there is no shortage of material, uniformity, and does not affect the normal operation of the machinery.
5.After the shutdown, cut off the power supply and clean and clean the paver.
Fourth, the bottom layer of the grinding.
After the paving of the bottom layer is completed, the bottom layer is smoothed
1.Use a paper cutter to cut the gutter hole.
2.After the strength of the environmentally friendly rubber particles, the joints and uneven parts in the site are carefully and meticulously polished with a grinding machine to ensure that the next process is carried out normally.
5. Spraying of top adhesive.
After the bottom layer is smoothed, the top adhesive is sprayed
1.According to the put construction line, spray the football field first, and use steel nails to fix the plastic sheet at the red and green lap to prevent pollution.
2.Adjust the speed of factorization in strict accordance with the ratio of raw materials, and stir evenly. Guaranteed fastest delivery to the jet hopper.
3.A special person monitors the glue spraying machine, controls the viscosity of the material, and grasps the amount of material in time. Note that when the sun is direct and the temperature is high in summer, the hopper of the glue spraying machine must be covered with a cover plate to prevent the thinner material from volatilizing too quickly.
4.The personnel holding the spray gun have a strong sense of responsibility, and grasp the thickness of the glue as required, which is uniform and consistent. The ingredients are used up on the same day, and no shutdown is allowed to rest in the middle to ensure the quality of spraying.
5.After the shutdown, cut off the power supply, carefully clean the glue sprayer, pipeline, and spray gun with thinner material, and put the machine in the designated place to prepare for the next day's work.
Sixth, the line is drawn and put out.
After the finishing of the top adhesive spraying, the marking and pay-off work is carried out
1.Carefully check the positioning dimensions.
2.The wire box holder checks the width every day, and must ensure that it is 5 cm wide. Aim at the vacant position, take it lightly, put it lightly, and compact it at any time, clean up the line box at any time, and do not allow residual paint to drip, and the painting personnel should be serious and responsible, so that the sprayed paint is not piled up, and it is uniform and consistent, and the power supply of the air compressor should be cut off at noon and the night should be closed, and the spray gun should be cleaned before the end of work.
