1. Foundation: The site foundation plays a crucial role in the artificial turf field. The flatness, stability, and drainage of the site foundation will all affect the use of the artificial turf field. Artificial turf has no standard regulations for the infrastructure. Currently used in artificial turf sports grounds are based on asphalt concrete, waterproof concrete type, gravel foundation, and foundations of PNS. What kind of foundation type and drainage system is selected is more about the functional requirements and economic conditions of the site. The requirements of the international football institutions for the playing field are stable and stable. It is recommended to use asphalt as the foundation, and more choices should be made for inner drainage of pipelines. In cold weather regions, it is hoped that geothermal systems will be increased. Ordinary stadiums or school playgrounds have actually chosen more than a turtle-type structure outside the drainage structure, taking into account the basis of the service life and the construction of the plastic foundation with the connection of the construction is convenient, the current application of asphalt concrete in domestic stadiums is more common. The design of the site should be based on the geological report of the site of the sports venue, the location of the annual precipitation and maximum precipitation, and the location of the site. Artificial turf sports ground is based on the carrier of artificial turf, and its quality will directly affect the performance of the entire artificial turf football field. The basis of the artificial turf football field is basically stable and does not collapse. According to its structure can be divided into a variety of surface: asphalt concrete surface, reinforced concrete surface, two gray stone surface and melon stone surface layer. Asphalt surface layer is more popular in the whole country, it has waterproof property, it can't make water directly infiltrate, and it can only rely on the slope of the slope. When the rainwater is relatively large, the water accumulated in the site will form a small stream of water, causing loss of quartz sand and rubber particles on the lawn, and there will be too much water at the edge of the site, making it difficult to discharge the accumulated water in a short time. The same problem exists with reinforced concrete surfaces. However, the gray number of the two gray stone surface itself can be adjusted to be small, and the melon stone itself has no ash number, so the seepage of the two surface layers is better. The size of the stone is the same as the size of the stone in the asphalt surface. The rainwater can directly penetrate into the gravel layer and the hard and hard soil layer below. This will reduce the loss of quartz sand-fat rubber particles on the lawn and relieve the water accumulation in the site. However, these two types of surfaces cannot be used in areas where the winter is relatively cold. Because the water that penetrates into the surface layer cannot be discharged in time, it will expand during the winter season, resulting in uneven surface appearance. The surface of the two gray stone mesa stone surface layer has good water permeability, and the surface layer is the same as the asphalt, and is relatively cheap in price. It is therefore advisable to use a tuffite face and a melon seed face as the site foundation for the artificial turf football field, but it is better to use bitumen or cement facings in areas that are colder in winter. The site foundation with asphalt or cement surface layer can refer to the construction requirements of the road surface. However, during the construction, attention should be paid to maintaining the overall shape, making the center low in the middle four weeks, and the slope should be uniformly maintained at 0.3% to 0.5%. Drainage should be established around the site. ditch. The site foundation of the limestone surface and the melange stone surface layer requires a pre-embedded drainage line. Regardless of the basis used, the quality of the product directly affects the quality of the surface. Therefore, in the foundation construction, the basic prime soil layer generally follows the “Technical Specifications for Highway Foundation Constructionâ€, and the reinforced concrete layer generally follows the “Construction Technical Specifications for Highway Cement Pavementâ€, and the asphalt concrete layer generally follows the “Construction Technical Specifications for Highway Asphalt Pavementâ€. 2. Take the line and find out the center of the site. According to the center point, determine the exact position of each point and line on the site. With reference to the field conditions on the sports grounds, site markings were drawn, and graphic design drawings and renderings were drawn to match the artificial turf with different properties and thicknesses. 3, carry out the basic treatment, repair, cleanup. The artificial turf is moved into the site and spread out in the direction of the transverse edge, and is sequentially pushed from one end of the longitudinal edge to one end of the crucible. Artificial turf must be laid by professionals using professional tools. After Chengyuan's materials arrive at the construction site, they are cut by construction personnel according to the requirements of the drawings. Each grass seam joint is glued with a special interface tape or sewed with a special machine to integrate the entire lawn. When installing, it is required that the humidity of the air should not be too large and construction on rainy or foggy days should be avoided. 4. Cut out the white grass line outside the lawn and set it aside for use. 5. Lay out 2cm~3cm from the joints of the green lawn and cut them with a lawn knife or a knife to make the lawns on both sides overlap as closely as possible. 6. Spread 20cm~30cm wide fiber cloth or non-woven fabric along the seam of the lawn. If it is wetted by water, it should be dried for a certain period of time to make it dry, and then the special glue should be evenly coated on the fiber cloth. Combine the lawns on both sides and glue them onto the fiber cloth. If there is a large gap in the joint, it can be cut at intervals of 2cm to 5cm and stretched toward the interface to ensure a beautiful appearance. 7. After the basic splicing of the lawn is completed, the position of each function line and point on the site shall be determined by pulling the cable again, cutting with a knife, drawing out the cut grass, putting fiber cloth, applying special glue, and preparing the original White straw is put back and the glue is pressed tight. It is more difficult to draw an arc in a narrow area such as a corner kick, and the entire corner area can be cut off, cut into small pieces, and then pieced back together. 8. After the turf is stitched, the part of the turf on the lawn needs to open with a knife, straighten the butt joint, remove the overlapped part, and then cement 9. After all the lawns have been processed, use the sand filling machine for sand injection, rubber injection, and bristles. Quartz sand is filled on the lawn to hide quartz sand from the roots of the grass and protect the grass. Then spread the rubber particles evenly on the quartz sand. The thickness of the filling quartz sand and rubber particles is determined according to different heights of the lawn, and the rubber particles are required to be about 10 mm below the surface of the grass. 10. Clean up the site, check the actual size of the site, strictly check whether the turf bonding is firm, and deal with the phenomenon of non-uniformity of quartz sand and rubber particles, and finish it.
