1. Foundation engineering
About foundations, there are mainly two kinds: cement concrete foundation and cement stone powder foundation (point me, check the super-economic cement stone powder foundation construction program).
How to construct here is not to go into details. When construction is finished, attention must be paid to smooth and dense construction. "Thousands of miles of embankment destroyed in ant nests" truth we all know, once the foundation ground appears a variety of pits, even if very small, after laying the lawn not only affects the aesthetic, but also sprain the ankles of athletes, then rework, it is not so easy! The second is the drainage problem: the use of turtle back drainage, two courts drainage ditches connected to form a circular drainage ditch, to meet the site drainage requirements. The horizontal and vertical slopes are <3 per thousand, and the surface should be smooth and smooth to ensure drainage.
2. Lawn laying and paving.
This is a strength + technology job! There are about 3 kilograms of grass per square metre. The width of a roll of grass is 4 meters, which is 50 meters long. That is 600 kilograms. To fully spread, but also to ensure that the next bonding link smoothly, then the distance between the two lawns must be grasped.
3. Brushing glue
Apart from the quality of glue (of course, Huashang is the use of special glue lawn, through the national environmental testing standards, please rest assured to use), should pay attention to the thickness of the brush, drying time. Uneven thickness will make the lawn uneven; glue drying time is too short, the lawn sticky, too long, the lawn will open glue after bonding. These are summed up by the construction experience of the construction master.
4. Stick the lawn.
The lawn was trimmed and sewed with special tools according to specifications, and the artificial lawn was bonded with special seam adhesive and seam belt.
5. Mosaic function line
According to the site marking and pavement drawings, make the thread and bond it.
6. Filled quartz sand.
Sand laying machine and special tools are used to wash quartz sand into the lawn, which is even and flat. The quartz sand is added 15-25 kg per square meter.
7. Fill rubber particles.
Scatter the rubber particles evenly onto the lawn. The rubber particles are 2 to 3 kilograms per square metre, and the specifications are 1 - 3 mm.
8. Completion of construction
Clean the site thoroughly, check the specific size of the site, whether the lawn is bonded firmly, whether the quartz sand layer is even.
The lawn project is finished.
Then how do we maintain it?
And then look down.
1. Basic requirements for maintenance:
Artificial grass lawn, artificial grass field maintenance, artificial grass, football field maintenance, artificial grass basketball court, artificial grass tennis court when the stadium artificial turf installation is completed, it will take at least two weeks to stabilize the grass fiber. Although sports events can be held during this period, we recommend that all heavy equipment and unnecessary traffic vehicles not enter the stadium. And during this period of time, to minimize the number of cleaning, especially not in high temperature cleaning. In addition, unlike natural grasslands, man-made turf often takes weeks of use and weathering to achieve optimal performance. This period of time not only requires the straw fiber to be stable, but also requires appropriate particle filling to achieve a comfortable, suitable for long-term movement of the ideal state.
2, cleaning and decontamination:
Rain is the best cleaner for artificial grass. It can gently wash away the dust, pollen and other airborne pollutants from grass fibers. In any case, artificial grass sites need to clear away rubbish in time and reduce the following problems:
(1) place enough rubbish bins to avoid spillage.
(2) draw out a special parking lane to reduce dirt and vehicle prints on the playground.
(3) emphasize smoke-free environment. If possible, use chewing gum similar to cigarettes.
3, small-scale cleaning:
It will be easier to clean paper, peanut shells, melon seeds and tapes in time after the game. A satisfactory vacuum cleaner can suck into paper, food residue and surface dust.
When using these machines, there are several points to note:
(1) brush type
The cleaner must have a synthetic fiber brush, similar to nylon or polyolefin, with a minimum length of 2.5 inches. Brushes should not contain metal or metal wires.
(2) brush installation
Proper use of the cleaner will not take away the rubber particles filled in the turf, so brush installation deserves special attention. The specific installation method depends on the type of cleaner, which will work very well when the installed brush barely touches the top of the straw fiber. Do not install the brush so low that it can be inserted into grass fibers, stuffing or padding. When the brush installation is too low, it will damage the turf and affect the filling. We do not recommend cleaning the soil with the cleaning machine.
(3) temperature limitation
In summer, if the temperature exceeds 33 degrees, please do not use the cleaning machine.
(4) vehicle emission
To prevent fire or to melt grass fibers because of high temperatures, do not park vehicles on turf without stalling. No matter what vehicle you use, do not exhaust the vehicle's gas in the sports field.
(5) oil spill, etc.
Keep lubricants, greases, liquids from spilling over or dropping onto your turf surface during the cleaning process, as these liquids can discolor the turf fiber and must not spill battery-like acidic liquids onto the grass.
(6), frequency
Generally, loose garbage is cleaned only when it is needed. In the frequent use of artificial grassland, it is usually cleaned twice a month.
4. Remove stains:
In most antifouling fibers, polyethylene is well known because most stains are caused by moisture, but polyethylene itself does not absorb moisture. Therefore, "dirt" on polyethylene fibers
