First, the construction process

Cleaning site (checking water) Testing water vapor Partially applying base oil Repairing potholes and thickening floor floors Making base materials Filling flats with surface materials Laminating the middle elastic layer Spraying the surface layer Streaking survives.

Second, the construction method

1. Repair the foundation: There are pits and cracks on the ground to make it flush with the ground.

2, The construction of the base material: According to the main agent: hardener ratio 3:1 After stirring evenly add 27% of black rubber particles, use the screw adjustment flat scraper, scraping about 10mm thickness. According to the principle of first in and out first: the main runway external auxiliary runway.

3. After the construction of the substrate is completed, test the water. If there is water accumulation, it shall be filled and the next process shall be performed.

4. After the construction surface material is fully stirred with the main agent: hardening agent ratio of 2:1, EPDM red particles and green particles are sprayed with a special sprayer, which is about 3 mm thick.

5, Runway marking

1. According to the standard 400-meter runway fixed point line. Line width 5 cm.

2. Use white urethane acrylate material and apply it with a line.

3. Use colored (yellow, blue, green, etc.) urethane acrylate materials, and paint them with different start lines and relay points to show the difference.

4. Clean up the on-site garbage and submit it to Party A for acceptance after survival.

4. Mixed plastic stadium construction process and method


 First, the construction process

Acceptance of site foundation basic treatment leveling paving middle elastic layer paving surface brushing or spraying wear-resistant anti-slip layer draw line to survive.

 

Second, the construction method

1. Acceptance of site foundation: According to the design standards, acceptance of the grass-roots flatness, slope and asphalt strength is mainly carried out.

2. Grassroots treatment: Properly repair a few uneven places, stir it with polyurethane glue and quartz sand, smooth the gap, and fill up the unevenness.

 

3. Leveling: Sprinkle water on all the sites, make a mark on the stagnant water, and wipe a little dent after glueing. The entire site will not have a large area of stagnant water.

4. The middle elastic layer of the paving: After the construction personnel arrives at the post, the mixing personnel starts the batching. The standard of the middle elastic layer is the prepolymer (Group A): the color paste (Group B) is equal to 1:2, and the mixture is uniform. Then, 25% of the total amount of black rubber particles were added and stirred. The trailer was sent to the site of the paving and was dumped on the base surface.

The paving personnel hold two teeth with a fixed height (1-8mm), spread the mixed glue and lay it flat, and do a defoaming treatment, using 5 kg of PU glue per square meter and 1.5 kg of rubber.

5, paving surface layer: stirring personnel according to Group A: Group B is equal to 1:1.5 ingredients, sent to the site, but also was a linear dumping.

The paving staff took a live 3mm gingivae, spread out the pure glue and laid out a defoaming treatment. The dosage per square meter was 3.3kg.

6, brush or spray wear non-slip layer: ingredients, use PU glue: acrylic paste equal to 1:

0.5 Mix the ingredients, add the appropriate amount of rubber, stir well, add the thinner to adjust the viscosity, and send it to the site.
