soccer grass paving the preparatory work before

soccer grass paving the preparatory work before
        ① soccer grass pavers should be checked before template location, elevation, branch and grass-roots level set solid wetting templates inside coat degreasing agent, cement siding coated with asphalt concrete and steel erection and dowel bar, rod and other settings circumstances, qualified before paving.
        ② Channel and set the security fence, picket and so on.
        Two soccer grass paving construction points
        ① paving the maximum thickness of more than once, you should paving and tap twice, but two layers of plaster once paved the interval must not exceed 30min. Should be slightly larger than the thickness of the upper lower that the total thickness of the lower layer thickness is preferably 35.
        ② paving thickness should consider tap the top left height. This height should be concrete pavement testing to determine the initial pilot phase, generally about 10%.
        ③ spade paving, the application of anti-buttoned spade shovel law prohibits throwing and columbine rake.
        ④ Each warehouse concrete paving, vibration, leveling, surface should be done continuously without interruption. Such interruptions should be set construction joints, and design requirements should be established in joint position.
        4 vibrators leveling construction points
        A good paving concrete mixture shall forthwith insert plate vibrator peace evenly tap. The product eliminates the need for concrete plastic tablet tap processes.
        2 Insert the vibrator frequency should be greater than 6000 min.
        3 plate vibrator effective role of depth is generally 18-25cm. Tap should be used 2 ~ 2kW flat vibrator (available when using the vacuum suction technology power smaller plate vibrator). Zhenping available 1 ~ 1kW of plate vibrator.
        4 vibrators vibrators should be inserted in the template to use (or concrete siding) edges, corners or the whole area of ​​early Zhen Zhen once the order early. Vibration should not be less than the same location 20s. Insert vibrator moving distance not greater than the radius of action of 1 to 5 times, its distance from the template is not to be greater than the radius of action of 0 to 5 times, and avoid collisions and steel templates. Then, and then plate vibrator fully vibrators board and the board should overlap between l0 ~ 20cm. The same position vibrated time when water-cement ratio should be less than 0.45 less than 30s, when the water-cement ratio should not be less than 0.45 15s, with no bubbles emerge and prevail glow cement mortar. If conditions then a small power plate vibrator best overall vibration level again.

monofilament has also been evolving form different concepts synthetic turf

Simulation concept grass

Mainly from the synthetic turf's appearance to be considered, focusing on synthetic turf simulation performance, this change from recent years gradually replace monofilament mesh grass grass seen in the current monofilament has become the market mainstream, and monofilament has also been evolving form different concepts synthetic turf. The author collection, lists the following seven categories that appear in the industry "new concept" synthetic turf:

Concept One: "ribbed" monofilament grass

"Ribbed" monofilament grass to mimic the body's natural hastily tendons structure, stabilize and support to increase the elasticity effect. In fact, from the microscopic point of view does increase cursive simulation results, from a macro point of view is difficult to see the actual results, and for synthetic turf sports performance changed little.

Concept II: "Hollow" monofilament grass

"Hollow" monofilament grass, in addition to the tendons mimic natural grass, but also adds a hollow structure, mainly played the role of water, also known as the "breath of grass", but in fact this tiny hollow structure difficult to achieve due to capillary action of water and breathing purposes.

Concept III: "Warrior" monofilament grass

Cursive section S-shaped structure, and mimic the characteristics of natural grass bent, called "Warrior" monofilament grass. However, after use, this advantage is not obvious, back in less effective.

Concept Four: "Diamond" monofilament grass

Cobalt Stone monofilament, by definition, grass fiber cross-section was diamond structures that mimic natural grass prismatic structure, which can increase the stiffness grass fibers, but the lawn Friction force change, to become slippery.

Concept Five: "net list" mixed woven grass

This series of synthetic turf is mainly mimic the characteristics of natural grass uneven thickness, but can only do two different blades, not the same as natural grass can wire every blade of grass is not the same thickness.

Concept Six: aromatic synthetic turf

Mainly imitate the natural grass aroma, one from the grass fiber to increase air freshener, two from the filler to increase air freshener, but either way, this fragrance can only be maintained for a short time, the longest non- more than six months, so the practical value is not high.

Concepts seven: "Z-shaped", "wavy" synthetic turf

In addition to the six kinds of simulation concepts grass, there are "Z-shaped", "wave-type" go knitting needles synthetic turf, mimic natural grass plants arranged in irregular features. However, this synthetic turf can not be done without a rule, do not fundamentally improve the grass-line binding force. On the surface, such a weaving method and traditional weaving methods spread out the effect is not much difference.

artificial grass and natural turf different

artificial grass and natural turf different

Active function compared with natural grass, artificial grass mortal venue construction is much greater hardness, chemical fiber friction coefficient is often less than the lawn grass blades, in football activities on the show as a lead ball is too fast, bounce rate is too high, Then increase the activity of the control of the ball member of the difficulty.

artificial grass lawn activity characteristics relative to the natural advantage on the field homogeneity excellent flatness should be much better, you can prevent abundant due to weather, maintenance and other elements of adverse site conditions formed, and then affect competition.

The impact of the situation on the air condition affecting natural lawn constituted by the green plants, can be subjected to reasonable light collaboration with these lifelong metabolic process receives carbon dioxide and release oxygen, and can receive sulfur dioxide, hydrogen fluoride, ammonia, chlorine and other toxic gases, purify the effect of air. There are distinct natural turf blocking effects of dust, measured according marked life in scraping thirty-four wind, bare ground air dust concentration of 13 times over the lawn. Studies show, 25 square meters of lawn can be a small reception I fully exhaled carbon dioxide, is converted into oxygen, contentment human respiratory oxygen required for the process. artificial grass is made of polyethylene, polypropylene and other polymers made from non-living matter, can not introduce new movement for green plants, and not having a conditioning effect of atmospheric oxygen balance. Although artificial grass can be blocked to some extent, the dust, but does not have to receive toxic gas purification function of the atmosphere. In addition, low levels of artificial grass fiber technology often contain chlorine impurities at high temperatures, strong sunlight premise would differentiate and release chlorine and damage air quality.

The impact of weather natural turf rootzones is mixed sediment body structure has plenty of pore water and precipitation processes can accumulate water, play water cultivation effect. Hot weather, the turf grass with roots deep in the water received through transpiration effect take four weeks the situation a lot of heat, useful for lowering the ground temperature, conditioning necessarily within the confines of the small weather. artificial grass plateau bed constructed from rubber, concrete or asphalt composition, water simply can not play the cultivation effect, so can not reduce the surface temperature and the heat capacity is small, resulting in surface temperature significantly higher than the air temperature, especially in the block-style stadium this problem is more severe. Summer noon hours, artificial grass field adjacent to the surface can observe a distinct air heat distorted picture. For the implementation of the data indicated, 30 ℃ high temperature above premise, the appearance of natural turf uniform temperature below the temperature of 2 ℃ to 3 ℃, while the artificial grass surface temperature is higher than the temperature 6 ℃ to 11 ℃, and with rising temperatures, artificial grass surface temperature rise should be clear than natural turf. In the summer, artificial grass surface temperature is very high, if the attack at this time compared to its use by intense friction, contact with the skin will suffer severe damage.

The final product of natural grass hay residues that occur in the floor bed sediment microbial differentiation effect, the conversion of organic matter in the soil from the new back. Final scraps non-toxic, harmless sediment inclusion bodies, one can add organic matter to improve after another he used to do.

Irreplaceable natural turf synthetic turf development

Irreplaceable natural turf synthetic turf development

In the United States, the majority of synthetic turf by the use of artificial grass fiber material is a high grade nylon material, but also the use of multiple fibers, rather than filling sand synthetic turf can be divided into two kinds of water seepage and impermeable. The lawn in shape resembles natural grass, partly with a layer of shock-absorbing foam cushion layer, shock-absorbing layer has a variety of substandard density and thickness.

Since the domestic real skill to master synthetic turf laying few manufacturers, but more for foreign skills, therefore, is not sufficient in the laying of sand synthetic turf, the extraordinary shock-absorbing foam cushion layer is paved by the foreign experts will need to complete. A layer of shock-absorbing foam underneath to smooth asphalt as a basis for the following also covered with asphalt gravel, sand and gravel as a base, and a drainage system in the structure is the most critical aspect. This type of synthetic turf course in the installation must be dedicated to the use of artificial grass machinery, extraordinary in some professional sports perhaps costly laying of installation is particularly important, otherwise it will not reach ground leveling and uniformity requirements, for example exercises for the 2008 Olympic hockey venue Beijing Lu City Sports School hockey skills and some order to meet the extraordinary demand for removable artificial grass, artificial grass tiles and other venues are required according to the above requirements for construction grim.

synthetic turf drainage design and some synthetic turf design of drainage systems, lawn permeable cushion, the base layer in the design of drainage channels, the construction of such structure is more complex lawn, a higher cost. However, some systems did not design the drainage system, it would have to rely on the natural slope of the surface drainage, and therefore require a higher surface construction. In the actual project construction, various factors should be invested with the investment side of the economy, characteristics and other factors, the actual use of the lawn fully integrated with scientific theory and technology as the basis, the greatest degree of realization of economic, applicable and effective principle.

China's synthetic turf popular slower, but developed quickly, before the majority of fake grass and synthetic turf completely rely on imports, and now, a lot of domestic lawns are beginning to export it. Especially in some synthetic turf manufacturers in Wuxi. Such as green synthetic turf, now export volume has exceeded domestic sales, the Chinese most of the fake turf production comes from Wuxi, Wuxi false to say that the lawn is the best in China, is also the largest city.

synthetic turf in a non-life plastic fiber products as raw materials, the use of artificial turf to be produced by the method. It is the solution to the use of high intensity, extreme adverse growing conditions and other natural and should not be difficult to grow grass lawn planting an important way. Compared with natural grass, synthetic turf has a very distinct advantages and disadvantages. If you can weather use, subject to rain, snow weather affect small; easy maintenance, low maintenance costs; material environment, the surface layer is recyclable, etc., is the irreplaceable natural turf, so, synthetic turf is ideal for comparing the frequency of use high school sports, or a variety of training courses.

this new type of artificial turf will be safer than natural turf

Rubber particles are worth mentioning. Were frozen and pulverized in a circular shape of the particles, and these particles remain in the suspension with sand inside. Some athletes said that those tiny particles will bounce the ball splash in all directions, and some players will even eat into many particles. Obviously, it takes some time to adapt to it. However, manufacturers say that particles during a period of time after the game, will be below the settling down of the fiber. Different designs, different intensity and fiber length has been widely used in such a turf soccer, baseball, tennis or golf. Colorado a tourist attraction, there's an 18-hole golf course 72 applied artificial turf.

Injury existed in the past have solved the problem of increasing. Bill Bashir, - an orthopedic doctor in the 2003 Sports pharmaceutical research report said, in the long run, this new type of artificial turf will be safer than natural turf. Because the growth of natural turf inconsistency of natural turf will continue to wear, flexibility gradually decreased, thus increasing the ankle injury, or other parts of the possibility of injury.

artificial turf is more durable than natural turf, use period is 8-12 years. artificial turf will not have uneven situation, that kind of situation easily lead to athlete injuries. A company's product known as "will not rot, mildew, will not hurt the foot, not hydrolysis, does not pollute the air, and will not allow bacteria to invade", which is in stark contrast to the natural turf. Occasional scrub further demonstrates that artificial turf requires very little time and effort to maintain. However, we can not inspire prematurely, because not everyone is able to accept the outset of this new high-tech turf. Steve Tingley, England Wembley Stadium, the former manager, said: "Today's artificial turf no problem, they are more than 80 years we have seen those terrible artificial turf is indeed much better, but they can maintain not free in a dark place, they are still easy to grow moss and algae in cold climates, they are still frozen, so subsoil heating, washing, and drainage is very important. Moreover, when the validity of fast artificial turf end, how do you deal with those plastic it? "

According to media reports, the South Africa World Cup for the first time using artificial lawn

According to media reports, the South Africa World Cup for the first time using artificial lawn, in the city of South Africa Paul Guagni Peter Mokaba Stadium (Peter Mokaba Stadium) held in Algeria and Slovenia games, becoming the FIFA World Cup finals for the first time in "artificial lawn" competition venues.

According to Peter Mokaba Stadium "artificial lawn" laying German manufacturer DESSO's introduction, soccer turf is 100% natural grass, but the grass grow under 200mm implanted layer 20 million synthetic root fibers used to reinforce the natural grass roots, synthetic fibers about grass roots 3% of the total. Should belong to strengthen the roots of the natural grass, the purpose is to make the venue during the World Cup to meet the high frequency and high intensity game.

Put fashionable point is "pseudo artificial lawn".

Currently, we have seen artificial lawn are based on factory equipment will synthesize artificial grass fibers woven in the fabric factory products, and this is called "Desso GrassMaster" sucked artificial lawn products fibrous roots machinery "sik into "natural" fabric "---- planting layer which, also need watering, pruning and pest control and other means of conservation of natural grass, so that its" pseudo "It is not false.

According to the same technology, the same as the World Cup in South Africa (Nelspruit) City Mbombela stadium (Mbombela Stadium) turf planting photos show outside the stadium turf should be cut after planting brought into the stadium pavement, which is today as much as several natural turf stadium pavement almost the same.
