2019 paying and fixing of Lawn

1. Check and accept the foundation works.

Remove debris from foundation. If there is any roughness, it should be repaired and leveled in time. Construction sites must be cleaned to ensure environmental cleanliness and construction quality.

2. Measurement and lofting

2.1 according to the plan of the design, perform measurement and lofting.

2.2 Use theodolite or other precision measuring instruments to measure whether the surrounding facilities meet the size of the stadium. If there is an unsuitable place, it should be modified immediately, allowing the error of 5 millimeters.

2.3 Pavement paving:

2.3.1 the lawn will be laid on the ground in accordance with the original specifications, and the 3~8 mesh should be lapped between the turf.

2.3.4 cut up the turf with lawn cutter. The joint should not be greater than 3 mm.

2.3.5 lay overlapping cloth under the cutting area, and use glue applicator to brush glue on the joint surface, referring to the dry touch after joining and knocking firmly.

3. Construction instructions for turf adhesion

3.1. It is necessary to clean and clean the turf bottom and interface cloth that needs to be bonded, and the surface is dry and moisture free.

3.2. The ambient temperature should be chosen above 5, and the construction should not be carried out in rainy and mildew weather, otherwise the bonding time will be too long or even cause non-sticking phenomenon.

4. the specific construction process:

4.1 glue: Require to use the glue applicator on the surface of the coating thickness uniform, can not repeatedly glue, otherwise there will be bubbling phenomenon, or even fall. The bottom cloth uses glue applicator, strictly control the thickness of glue, pay attention to the appropriate speed of glue coating, glue coating should be applied on the two bonded surface.

4.2 Viscosity: According to the actual influence of temperature, humidity, air pressure and other conditions at that time, reasonably control the drying time. Generally, 10 to 30 minutes after gelatinization, eight or nine of the glue is dry, and the touch is not sticky. When bonding, it requires a one-time alignment of the adhesive, and must not be glued and then moved back to the bonded object.

4.3 Pressure: After bonding, remove the surface debris, use a special rubber hammer from the bonding place to both sides of the hammer, so that the surface of the full contact compact, bonding more firmly.

4.4 curing: the curing time is usually three days, and the final strength is usually ten days. During curing, attention should be paid to maintaining, avoiding exposure, flooding and moving, reaching the best state of adhesion.

4.5 No quartz sand and rubber particles were bonded after bonding.
