1. Check and accept basic engineering:
Remove the debris from the foundation. If there is any unevenness, it should be repaired and leveled in time. The construction site must be clean to ensure the cleanliness of the environment and the quality of construction.
2. Measurement and stakeout:
According to the plan of the design drawing, perform measurement and stakeout. Use theodolite or other precision measuring instruments to measure whether the surrounding facilities meet the size of the sports field. If there is any unsuitability, it should be corrected immediately, and the allowable error is 5 mm.
Pavement: Pave the turf on the ground according to the original specifications, and overlap between the turf by 3~8 mm.
Cut the overlapped turf evenly with a lawn cutter. The seam should not be larger than 3 mm. Lay the lap cloth under the cutting area, and use a glue applicator to brush the bonding glue on the bonding surface. After the fingers are dry, they are bonded and knocked firmly.
3. Description of turf bonding construction process:
The bottom surface of the turf to be bonded, the interface cloth, etc. must be cleaned, and the surface must be dry and moisture-free.
The ambient temperature should be above 5℃ for construction. Furthermore, it is not suitable for construction under rain and mildew weather, otherwise it will lead to long bonding time or even non-sticking phenomenon.
4. Specific construction process:
Gluing: It is required to use a glue applicator to apply a uniform thickness on the surface, and do not apply the glue repeatedly, otherwise blistering or even falling will occur. Use a glue applicator at the bottom to strictly control the thickness of the glue, pay attention to the appropriate speed of glue application, and apply the glue to the two bonding surfaces to be bonded separately.
Stickiness: According to the actual influence of the temperature, humidity, air pressure and other conditions at the time, reasonably control the drying time. Generally, within 10-30 minutes after gluing, the glue should reach 80% to 90% dry and it is better to touch it without sticking. When bonding, it is required to align and stick firmly at one time, and must not move the bonded objects back and forth after bonding.
Pressure: After bonding, remove the debris on the surface, and use a special rubber hammer to hammer hard from the bonding point to both sides, so that the surface is fully contacted and dense, and the bonding is stronger.
curing: the curing time is generally three days, and the final strength of the test is generally ten days. During the curing period, attention should be paid to maintenance, avoid exposure to the sun, water immersion and movement, and it has reached an excellent state of bonding.
After bonding, before sprinkling quartz sand and rubber particles, an imported cleaner should be used to clean the turf cut fragments of the field.
