Grassman artificial grass turf supplier’s artificial turf paving, transportation, maintenance and maintenance instructions
A. The foundation is generally cast-in-place cement concrete or asphalt, which has certain strength and stability.
B. The foundation must not have cracks and peeling or sanding caused by freezing.
C. the flatness of the foundation, the error of a 3-meter ruler is less than 4mm, and it has a certain slope, generally 3-5%, to facilitate drainage in rainy days.
D. In freezing areas, anti-freezing technology should be adopted. Generally, a layer of geotextile is added between the asphalt layer and the gravel layer to buffer, and the foundation of the trench along the water should be treated with special waterproofing.
E. The surface of the foundation should be kept clean and dry. After the asphalt foundation is completed, a maintenance period of about 30 days should be guaranteed to make the low boiling point components of the asphalt surface volatilize and ensure that the foundation surface layer has sufficient bonding strength.
F. The concrete foundation should also have a maintenance period of about 30 days. For large-scale use, it should be considered to reserve expansion joints, and the surface layer should be smoothed.
G. basic technical indicators of asphalt concrete
1) The compactness of the foundation after rolling is greater than 95%
2) The compaction density of subgrade graded sand and gravel is more than 2.3kg/cm2, the surface is smooth, and it is solid without sand nests and plum blossoms.
3) The asphalt surface should be free of oil, cracks, cracks, cracks, and water blocking.
⒉ Acceptance procedure
A. Check the flatness and slope of the site first, and correct the unqualified parts.
B. Check the acceptance against the data, and the construction unit shall provide the completion data.
C. Prepare a material plan according to the amount of the project to ensure the quality and duration of the construction.
D. Clean up the site, clean up the site where the lawn needs to be laid, and remove oil, debris, mud and other garbage.
E. The area around the site should be kept clean, and garbage is strictly prohibited from entering the site.
F. For old sites that have been constructed for a long time, the expansion joints must be cleaned up and filled with new materials.
(Two). paving steps
Ⅰ. Clean the bottom of the lawn, non-woven fabric, seam cloth, etc. that need to be bonded, and the surface is dry and moisture-free.
Ⅱ. The temperature of the construction environment should be between 10℃-40℃. It is not suitable to construct in rainy and humid weather, otherwise it will lead to the phenomenon of weak bonding.
Specific construction steps:
It is required to use a brush to apply a uniform thickness on the bottom of the lawn. Do not apply the glue repeatedly, otherwise it will cause blistering or even falling. Strictly control the thickness of the glue, pay attention to the appropriate speed of glue, and apply them to the two bonding surfaces to be bonded. superior. (2). Bonding:
According to the temperature, humidity and other conditions at the time, the drying time should be reasonably controlled. Generally, it is appropriate to apply the glue for 10-15 minutes. When bonding, it is required to align and stick firmly at one time. Never move the bonded objects back and forth after bonding.
After bonding, remove the debris on the surface, and use a special rubber hammer to hammer hard from the bonding point to both sides to make the surface fully bonded and tighter.
The curing time is generally three days, and the final strength of the test is generally ten days. Therefore, it is necessary to pay close attention to its maintenance during the curing period to avoid excessive exposure, water invasion and movement to achieve the best bonding state.
(5). After bonding, clean the cut pieces of the site before filling with quartz sand and rubber pellets.
(three), engineering quality inspection requirements
A. After the completion of the site, the markings should be accurate and the colors should be consistent;
B. There should be no obvious seams and height differences in the venue;
C. The joints of the lawn should be firmly bonded without air bubbles;
D. The filling should be uniform, smooth and dense;
E. At the same time, refer to the relevant inspection methods of the national artificial material sports venues use requirements and inspection methods (Grassman artificial grass turf supplier’s artificial turf field).
(4) Safety and civilized measures
A. Fireworks are strictly prohibited in the construction site.
B. It is strictly forbidden to enter the construction site by persons irrelevant to the construction.
C. The garbage generated during daily construction shall be cleaned up in time and transported to an appropriate place for unified treatment after the completion of the project.
special attention items:
A. During the construction period, attention should be paid to weather changes, work arrangements should be adjusted in time, attention should be paid to the solidification period of the glue, and it is strictly forbidden to use dehydration in rainy weather or when the glue does not meet the instructions for use.
B. Construction personnel are strictly required to pay attention to safety when using knives. When replacing the blades, do not throw waste blades in the field to prevent the occurrence of scratches during the use of the field.
C, glue and other items are flammable. During the construction period, fireworks are strictly prohibited.
D. When using, strictly control the amount of glue used to ensure the strength of the lawn.
E. Before using the quartz sand, please make sure that the quartz sand is dry.
Grassman artificial grass turf supplier’s artificial turf is generally transported by car: In the loading stage before transportation, the factory is responsible for the loading process of the goods to ensure that the lawn does not wrinkle during the loading process. When the ropes of the fixed goods are in contact with the goods, a soft object should be used in the middle of the lawn roll. Separate it to reduce the strangulation of the lawn roll.
During the transportation, the freight company is responsible for the safety of the lawn. It must not be exposed to rain, fire, or damage.
After the goods arrive at the site, the receiving party is responsible for the safety of the lawn. During the unloading process, keep the lawn packaging intact and prevent the lawn from being damaged (a special forklift is recommended).
Three, maintenance and maintenance
1. Basic requirements for maintenance:
A. Keep the site clean and control the use of the site.
B. Establish signs of “No Smoking” and “No Food in the Site” shall be erected around the grass.
C. motor vehicles and animals should not enter the sports field.
D. reduce the number of cleaning, clean at high temperature.
E. set up enough trash cans.
F. Small damages should be repaired in time.
2. Cleaning and maintenance:
A. After the game, use a vacuum cleaner to clean up paper, nut shells and other debris in time.
B. Use a special brush to comb the grass seedlings every two weeks to remove the sundries on the lawn.
C. Use a special rake to entrain quartz sand or rubber pellets once a month or after frequent competitions.
D. the dust on the turf will be washed away when it rains, or washed manually.
E. When the summer is hot, you can sprinkle the lawn with water to cool down to keep the athletes cool and comfortable.
3. Removal of stains:
