Español1. Site leveling and soil compaction
Site flatness: The pass rate of flatness is above 95%, and the compacted density of plain soil is above 95%
2. Construction of cement concrete foundation
Site foundation acceptance
A. Conduct on-site measurement and inspection of the foundation, and compare it with your foundation acceptance
Construction can only be carried out when the data is verified and meets the construction requirements. For damaged foundations, repair plans should be proposed in a timely manner.
B. Site cleaning; Remove all debris from the foundation, rinse thoroughly, and then blow dry with a fan.
3. Surveying and setting out
A. To ensure the quality and flatness of artificial grass paving, in accordance with FIFA regulations
The regulations issued require that the quality and appearance of artificial grass be ensured in the future,
According to the drawing requirements, locate the longitudinal and transverse axes of the playground and locate the center position of the playground,
Locate the boundaries around the playground.
B. According to the specifications of the design drawings and the planning, measurement, and layout of the artificial turf sports field
4. Laying artificial turf damping cushion
A synthetic material elastomer laid under artificial turf that can absorb impact force,
It has high impact absorption, good drainage and moisturizing properties. Absorbing up to 55% of the impact of the court, increasing the elasticity of the artificial turf, making it closer to a good natural turf, can avoid sports injuries caused by sudden stops during the kicking process, and achieve a comfortable effect of good foot and ball sensation.
5. Paving artificial grass
A. After the setting out is completed, the artificial turf court will be arranged according to the specifications, horizontally and in order from the center
Lay and install on both sides.
B. Lay the entire roll of artificial turf on the court according to the manufacturer's laying plan.
C. It is advisable to overlap the dividing and joining areas by 10 to 500px.
D. Fix the bottom lining material under the cutting line to the foundation surface and place it on the joint surface
Apply bonding adhesive and wait for the contact surface to dry before making the joint. After joining, overlap and overlap
Trim the area flush.
6. Installation of football field markings
After the completion of the entire joint project, proceed with the drawing of the football field,
Strictly follow the design drawings and IAAF standards for line drawing engineering. Draw lines on
When cutting, pay attention to the straightness of the cutting. When bonding white lines, it is important to
Apply the adhesive evenly to ensure a stable adhesion.
Design according to FIFA stadium rules, set out various signage lines on the football field, etc.
After the completion of marking and paving, it is necessary to check whether each junction area is sturdy and whether the intersection angle and lines are flush.
7. Quartz sand filling
A. Quartz sand can be laid only after the artificial lawn playground is installed.
B. The special quartz sand paver for artificial grass shall be laid from outside to inside, and the paving amount shall be 26 ± 1kg/㎡. The forward speed of the paver and the paving amount shall be average.
C. After laying quartz sand, it is necessary to check whether it is flat and sufficient, and if it is insufficient, it is necessary to add it.
D. Quartz sand paving and the site must be kept dry to facilitate the flow paving of stone sand.
8. Environmentally friendly particle filling
A. Elastic particles can be laid only after quartz sand pavement is completed.
B. The laying of elastic particles is the same as that of quartz sand from the outside to the inside
The paving volume of 1 kg/㎡ should be evenly distributed, and the forward speed and paving volume of the paving machine should be averaged.
C. After laying the elastic particles, it is necessary to check whether they are flat and sufficient, and add them appropriately if there are any deficiencies.
9. Completion and site clearance
After all processes are completed, clean the site and remove impurities and garbage generated during construction.Clean up. Delivered for use after completion acceptance.
