How to renovate artificial turf? How to replace an aging lawn

Refurbishment means removing the old one and replacing it with the new one. Then the first step is demolition, which is the key part. The first thing to pay attention to in the demolition process is not to destroy the original foundation, the foundation is generally cement, asphalt, or other ash cushion, the lawn is bonded to the ground or seam belt by adhesive during the installation process, the non-woven fabric is above, the lawn and the bonding layer are removed with tools in the demolition process, and the potholes and potholes that do not destroy the foundation are used.

Pay attention to the handling and cleaning of old turf, quartz sand, rubber particles, the old materials can not be used, after many years of use of the old materials have long lost their inherent properties, which are mixed with a lot of dust and other garbage and dirty things. These waste materials are dismantled in tons, so in the process of full consideration, many novices to see the site, looking at the lawn of the site is close to bald, thinking that the need to carry and clean up the garbage will be less, in fact, this is not the case. Because when building a new site, the filled particles, quartz sand is almost unchanged, take a standard football field as an example, the quartz sand it fills is about more than 200 tons, this is a very large garbage cleaning work, so when making a budget, it is necessary to fully consider the site before paving the new artificial turf, be sure to clean up the site, and if there is a condition, it is better to wash it with water, clean up the floating soil dust on the site, and then start paving construction.

Usually artificial turf is damaged and then applied through the relevant renovation process, and the same is true for natural turf, which is degraded or damaged. While these may not be applicable to artificial turf, it's good to have a little more knowledge. In order to prolong the service life of natural lawn, renewal and rejuvenation is one of the ways to ensure the durability of the lawn, mainly involving three types: strip renewal, root regeneration and replanting.

The so-called strip renewal method is to dig up a 50-centimeter-wide strip of grass with stolons and root in sections every 50 centimeters, then add peat soil or compost soil, and flatten the strip of land from scratch. Therefore, unlike artificial turf, this kind of turf will age and degrade after a certain age line, so it can be regrown.

Due to the influence of soil, climate and other factors, the natural lawn will gradually degrade, at this time, it is necessary to use a hole punch to make many holes in the lawn, the depth of the holes is about 10 cm; Fertilizer is also applied to the holes to encourage the growth of new roots. Or it is directly used to cut off the roots of rotary tillage, so that the turfgrass will grow a lot of new seedlings, obviously artificial turf does not need to do this. If some areas of the natural lawn are encroached upon by weeds, it is necessary to remove the weeds and carry out off-site seedling replanting in time, it should be noted that the turf must be trimmed before transplanting, and after replanting, it should be stepped on, so that the turf and the soil are closely connected, which is the same as the principle of close integration of artificial turf and foundation.

The renovation of artificial turf fields requires the removal of the old artificial turf and the replacement of the artificial turf with a new one. The first step is to remove the artificial turf, which is a key part. The first thing to pay attention to in the process of dismantling artificial turf is not to destroy (remove) the original artificial turf foundation, the artificial turf foundation is generally made of cement, asphalt, or other ash cushion, and the artificial turf is bonded to the ground or seam belt and non-woven fabric through adhesives during the installation process.

In addition, these waste materials are dismantled in tons, so in the process of full consideration, many novices to see the site, see the artificial lawn of the site is close to bald, thinking that the need to carry and clean up the garbage will be less, but this is not the case. Because the amount of particles and quartz sand filled in the construction of a new artificial turf field is basically unchanged, taking a standard football field as an example, the amount of quartz sand filled is about 200 tons, so this is a very large garbage removal work, so it must be fully considered when making a budget. After many years of use, these old materials have long lost their inherent properties, which are mixed with a lot of dust and other garbage and dirty things, and no longer have safety performance.

Before paving a new artificial turf, be sure to clean the site first, if possible, it is best to rinse it with water to clean up the floating soil and dust on the site, and then further start to pave the artificial turf.

Every year, lawns suffer from alopecia areata caused by human trampling, pest and disease damage, local drought, flooding and management errors, which greatly affects the grassland landscape. Alopecia areata repair technology is an effective measure to compensate for lawn alopecia areata and maintain a good density of grass, and the specific operation methods are as follows:

Alopecia areata is large, clearly exposed to the surface or has a diameter of more than 10 cm, and should be repaired at any time. When the rate of alopecia areata is more than 10, it should be repaired intensively.

The right time for repair

1.In spring, grass seeds are replanted with watering and green water. First of all, loosen the bald topsoil, sprinkle the seeds in, cover the soil and compact, and grow new seedlings after watering.

2.Patching during the rainy season. Use rainy days to loosen the topsoil in the bald area, and use a small shovel to dig into a small ditch or pit, plant grass blocks or grass blankets in it, compact and water, it is easy to survive.

In the growing season of the grass, combined with the irrigation of the grass, it is found that the larger alopecia areata can be sprinkled into the grass seeds for reseeding at any time.

Although turfgrass is perennial, its life span is relatively short, and we should take necessary technical measures to extend the life of turf as much as possible. Rejuvenation is an important part of the care to ensure the longevity of the lawn, and it can be done in the following ways:

Strip renewal method: for the grass with stolons and branching roots, such as knotweed, dogtooth roots, etc., after growing to a certain age, the grass roots are densely aged, and the spreading ability is degraded, and a 50-centimeter-wide strip can be dug up every 50 centimeters, and peat soil or compost soil is added, and the empty strip of land is re-leveled, and it can be full after one or two years, and then the remaining 50 centimeters are dug up, so that the cycle repeats itself, and it can be fully renewed once in 4 years.

Broken root renewal method: 1Due to the degradation of the lawn caused by soil compaction, we can regularly use a hole punch to tie the lawn floor into many holes in the built lawn.

The depth of the hole is about 10 cm, and fertilizer is applied to the hole to promote the growth of new roots. In addition, it can also be rolled with a nail tube with a tooth length of three or four centimeters, which can also play the role of loosening the soil and cutting off the old roots, and then sprinkle fertilizer on the lawn to promote its germination and new sprouts, so as to achieve the purpose of renewal and rejuvenation.

2.For some plots with thick dead grass layer, soil compaction, uneven turfgrass density and long growth period, rotary tillage and root cutting cultivation measures can be adopted. The method is to use a rotary tiller to rotate once, and then water and fertilize, which not only achieves the effect of cutting off the old roots, but also makes the turfgrass grow many new seedlings.

Replanting turf: For slight bald or local weed infestation, remove weeds and carry out off-site seedling replanting in time. The turf should be pruned before transplanting, and stepped on after replanting, so that the turf and the soil are tightly combined.

One-time renewal method: If the lawn is degraded and bare up to 80 or more, it can be replanted after turning it with a tractor. After planting, the maintenance management is strengthened, and the replanted lawn will soon be revived.

Oh, and the general word is to replant the grass and then water more, fertilize more, and prune frequently.

Key points for the maintenance of artificial turf fields

Point 1: Artificial turf needs to be kept clean.

Under normal circumstances, all kinds of dust in the air do not need to be deliberately cleaned, and natural rain can play a washing role. However, for some empty sports venues, such an ideal state is rare, and it is still necessary to clean up all kinds of residues on the turf in time, such as confetti, melon and fruit drinks, etc. Lightweight garbage can be disposed of with a vacuum cleaner, larger ones can be removed with a brush, and stains can be treated with a liquid of the corresponding ingredient and quickly rinsed with water.

Point 2: The pressure per unit area should be controlled.

No vehicles are allowed on the artificial turf field, and heavy objects must not be piled up. Artificial turf has its own upright and resilient nature, but it can also crush the grass if it is too heavy or too long. Artificial turf fields cannot be used for sports such as javelins that require the use of sharp sports equipment.

Spikes cannot be worn in soccer matches, and can be replaced by spikes.

Point 3: Daily supervision and inspection.

It is important that the field manager walks along the field frequently to inspect and clean up any damage to the field, and that any problems found should be assessed and dealt with appropriately to avoid athletes tripping due to turf damage. For fields without filler, special attention should be paid to the growth of algae plants in sports fields, especially in some areas with warm climates.

Frequency of maintenance of professional artificial sports turf fields

Professional artificial sports turf fields can be scheduled for seasonal or annual maintenance, depending on the use, and regular inspections can determine the daily needs of each specific area. Here, FIFA's artificial turf maintenance guide provides us with some suggestions and methods.

1. Cleaning and maintenance.

1. Use a vacuum cleaner to clean the paper, husks and other debris on the artificial turf in time after the race.

2. Use a special rake to level the quartz sand or rubber pellets of the artificial turf once a month or after frequent competitions.

3. Comb the grass seedlings on the artificial turf with a special brush every two weeks to remove dirt and leaves and other debris on the artificial turf.

4 Dust on artificial turf will be washed away when it rains, or washed by hand.

5 When it is hot in summer, you can sprinkle artificial turf with water to cool down and keep athletes cool and comfortable.

2. Removal of stains.

When it comes to sports artificial turf, rain is your best washer. Rainwater gently washes away dust, pollen and scattered contaminants from grass fibers. The most important cleaning of artificial turf is to remove the garbage generated in the use of the site in time.

It will be easier to vacuum the paper, peanut shells, melon seeds, tape, etc. on the artificial turf in time after the race.

1. For "watery" stains such as juice, milk, ice cream, and blood stains, scrub the artificial turf with soapy water first, and then rinse the artificial turf with soapy water for the length of water; If necessary, blot dry with an absorbent towel.

2 nail polish, which can be wiped with acetone.

3 Paraffin, asphalt and asphalt, vigorously wipe or wipe the artificial turf with a sponge dipped in perchloroethylene.

4. Shoe polish, sunscreen oil, ballpoint pen oil, etc., can be dipped in perchloroethylene sponge to wipe the artificial turf, and the artificial turf can be blotted dry with a towel with strong adsorption.

5 If the artificial turf is stained with chewing gum, you can spray it into small pieces with Freon and then remove the residue.

6 Paints, coatings, etc., can be wiped with turpentine or paint remover, and decontaminated with detergent and water. Then rinse the detergent with cold water and wipe the artificial turf vigorously, and wipe the artificial turf with a sponge dipped in perchloroethylene.

7. If there is fungus or mildew spots on the artificial turf, you can pour 1% hydrogen peroxide into the water, and soak it thoroughly with water after wiping.

3. Check and repair.

1. Carefully check whether the sutures of the artificial turf are loose, and whether the bottom of the entire artificial turf is damaged, torn, burned, etc. Major repairs should be made in time to contact the pavement company.

2 Heavy rain erosion and cleaning will cause a small amount of filling of artificial turf to be lost. The place where the artificial turf needs to be filled can be sprinkled with some quartz sand and rubber particles, and completely swept into the artificial turf.

Summary. The easiest way to remove old lawn is to turn it over with a plough, so the roots die in the sun, and pesticides such as paraquat must not be used, as this can pollute the land.

The easiest way to remove old lawns is to turn the entire lawn over with a plow, as the roots of the grass will die completely after exposure to the sun, and pesticides such as paraquat must not be used, otherwise the land will be polluted.

How do you prepare the ground before planting a lawn?

Thank you. The backfill is full and slightly higher than the design elevation, and the general height difference is within 3 5 cm of collapse. Remove all small rocks and other objects within 30cm of the site.

If you design a grass with terrain, make sure that the terrain is smooth and full. Sprinkle perlite and humus, river sand, etc. to improve the soil, if the soil after the wooden strip is rolled out and sprinkled with river sand, in order to ensure the subsequent growth of the grass pat, you can also sprinkle some compound fertilizer appropriately, and apply foot fertilizer at the same time as preparing the land. Hu Yan.

Lawn planting: Before planting, the uneven soil layer will be flattened, and when planting, the pull line should be used to keep the lawn flat, tidy and neat.

Rolling: Generally, it is necessary to carry out three times of rolling to ensure that the sand layer and the turf are fully connected and touched, and there are many ways to tremble and roll: if the turf area is large, you can use a roller car, if the area is average, you can make your own drum, and you can also pull it by manpower.

If it is a sporadic turf field, you can let the workers pat it vigorously with an iron eggplant spade.

Watering: If it is a large grassland such as parks, golf meadows, etc., an automatic sprinkler irrigation system will generally be installed, and the grass will be opened immediately after the completion of the laying. In the case of manual watering, it is important to pay attention to the first watering to water thoroughly, and to consider the settlement of soil, sand, and sand on the turf.

Daily pruning: Generally, the grass that has just been laid is a fine chain that does not need to be grassed, because after rolling and watering, the grass is compact. It takes about 10 days to start mowing.
