It is a kind of chemical product with natural grass movement performance. Grass synthetic fiber is implanted on woven base cloth, and the back is coated with fixed coating.
Its raw materials are mainly polyethylene (PE) and polypropylene (PP), as well as polyvinyl chloride and polyamide.
The leaves are as green as natural grass, adding ultraviolet absorbent and antistatic agent to ensure the high performance of grass silk.
Sand-free football field lawn is widely used in various sports venues, without filling particles and quartz sand, avoid gravel into shoes, reduce maintenance costs, improve sports experience.
Construction technology of lawn of sand-free football field:
Construction preparation, inspection and acceptance of foundation works. Remove debris from the foundation. If there is uneven, should be repaired in time. The construction site must be kept clean to ensure the cleanliness of the environment and the quality of construction
During the construction survey, the construction site shall be delimited according to the owner's requirements on the construction site, and the construction area shall be expanded by more than 5m according to the actual construction area.
According to the actual situation of the site, the original elevation point and the owner's requirements of the base plane or elevation, set up the water grid. That is, every 5 meters nail a steel drill pipe, uniform leveling line, and marked with red paint. In particular, a long drill pipe with obvious protective marks is nailed on the large corners of the four sides to avoid damage.
According to the direction and size of the site slope, adjust the corresponding elevation on the original elevation to reduce the deviation of the lower construction.
The first step: level the site, backfill and level the earthwork, and use the roller to fully roll to compactness;
The second step: lay 15cm graded gravel layer on the compacted soil layer (specific construction is determined according to the design), and roll it fully with a roller until it is compacted;
The third step: pouring 20cm commercial concrete (determined according to the design), fully vibrating and compacting with plane vibration plate, manually leveling the slope on the surface of concrete, and finally covering and curing with plastic film;
The fourth step: after the concrete is completely cured (specific curing time is analyzed according to the actual situation of the project), the uneven part of the concrete surface should be partially repaired to ensure the smoothness and compliance of the concrete surface;
The fifth step: Lay artificial lawn, each lawn seam should be pasted with special adhesive, paste the joint should be more than 10cm;
The sixth step: After laying the lawn, use the special roller for leveling treatment.
