1, Site formation, soil consolidation
Site flatness: pass rate of flatness is above 95%, compaction density of plain soil is above 95%
2, Cement concrete foundation construction
Site acceptance
A. Conduct on-site measurement and inspection of the foundation and check against your basic acceptance Data verification, construction can only be completed when the construction requirements are met, and the foundation is damaged and propose a repair plan in time.
B. Clean up on site; remove all debris on the foundation and rinse. Blow dry the fan.
3, measurement lofting
A. In order to ensure the quality and flatness of artificial grass paving, it is in line with FIFA. Promulgated rules require that at the same time ensure the quality and perception of artificial grass in the future,
According to the requirements of the drawings, the vertical and horizontal axes of the playground should be located to locate the center of the playground. Position the perimeter of the playground.
B. According to the specifications of design drawings and artificial turf sports field planning, measurement and lofting
4, lay artificial grass cushion
Synthetic elastomer that can absorb impact under the artificial turf. With high impact absorption, good drainage and moisturizing properties.
So that the impact of the stadium can absorb up to 55%, increase the flexibility of the ball artificial grass, make it closer to a good natural turf to avoid an emergency stop during kicking.
The sports injuries that occur in turn turn into a comfortable feeling of sporty feeling and ball.
5. Paving artificial grass
A. The artificial turf court will be in accordance with the specifications after completion of lofting. Lay the installation on both sides.
B. Lay the entire roll of artificial grass on the court according to the layout of the manufacturer.
C, partitions and junctions must be overlapped 10 ~ 500px is appropriate.
D. Attach the bottom line of the cutting line to the base surface and join the base apply adhesive on the brush, dry the contact surface for bonding, and reattach office trims flush.
6, football field marking installation
After the completion of the joint project, the line drawing of the football field will be carried out.
Strictly follow the design drawings and the IAAF standards to draw lines. Line drawing When cutting, pay attention to the linearity of the cut. When bonding white lines, be sure to brush the adhesive evenly to make it stick. Designed according to the rules of the FIFA Sports Ground, setting out the various lines on the football field.
After the marking pavement is completed, it is necessary to check whether each junction area is firm and check whether the intersection angle and the line are even.
7, quartz sand filling
A. After the artificial grass sports field is installed and completed, quartz sand can be laid.
B. The artificial quartz sand paving machine for artificial grass lays from outside to inside, according to 26±1kg/m2. Laying the amount of paving, the paving machine forward speed and spread should be averaged.
C. After the quartz sand is laid, it is required to check whether it is smooth and sufficient.
D. Paving quartz sand and site shall be kept dry to facilitate the flow of stone sand.
8, environmental particle filling
A. After the paving of quartz sand is completed, the elastic particles can be laid.
B. Laying of elastic particles is laid from the outside to the inside like quartz sand, according to 4±, the paving amount of 1kg/m2 is laid, and the advance speed and paving amount of the paving machine should be averaged.
C. After the elastic particles are laid, check whether they are smooth and sufficient.
9. Completed clearance
After the completion of all processes, clean up the site and remove impurities and trash from the construction.
