Basic practice and construction of artificial turf football field

Foundation requirements: The artificial lawn building foundation can be divided into three materials: cement concrete foundation, asphalt foundation and lime-soil foundation. Before the construction of artificial lawn, the foundation quality must be checked and accepted, and the company will designate a special person to check and accept, and form a foundation acceptance report. Construction can only be started after it is qualified, and construction is prohibited if it is unqualified.

A, construction preparation:

1. Prepare the construction plan and submit it to the company for review.

2. Plan the amount of engineering materials to ensure the construction quality and time limit for a project.

Second, the construction process:

1, basic processing

2. Clean up the site, clean up the site that needs to be mowed, and remove oil, dirt and other garbage.

3, the scene around should be kept clean, it is forbidden to garbage.

4. For the old site that has been built for a long time, the expansion joints must be cleaned and filled with new materials.

5, tape laying

6. The tapes shall be laid in a single layer and arranged in the forward direction, and each tape must be spliced completely.

7, the underlying tape must be laid flat, there can be no wrinkling phenomenon.

8, both ends of the tape must be fixed.

Third, the lawn laying:

1, artificial grass arrived at the construction site, calculated according to the drawings.

2. Use special tools to lay, level, trim and sew the lawn, and the direction of grass seedlings must be consistent, otherwise it is easy to produce visual color difference.

3. Connect the lawn joint with special joint waterproof glue and adhesive tape, and then compact it after the glue produces adhesive force.

4. After bonding, check whether it is smooth and firm.

5, according to the requirements of drawings on the surface of the line, splicing and inspection.

6. Quartz sand and rubber particles must be inspected and verified before filling. Quartz sand is injected into the lawn to hide it in the roots of grass hairs, thus protecting the grass hairs and making the lawn more durable. The thickness of the injected quartz sand depends on the different heights of the lawn, and the best effect is that the quartz sand surface is about 5mm lower than the grass surface.

7. Filling method of quartz sand and rubber particles:

(1) mechanical filling (grinding machine).

(2) artificial paving.
