In any case, the length must be more than the width.

artificial lawn Gate Stadium draw lines: the venue should be in accordance with the plan to draw clear lines. The line width of not more than 12 cm, shall not be made \ U +201 CV \ U +201 D-shaped grooves. The longer of the two lines called edges, the shorter two lines called the goal line. The venue the middle to draw a line across the stadium, called midline. An obvious mark the center of the field should be done, and this point is the center of the circle, the radius of 9.15 m, draw a circle called the center circle. Each vertical side venues on each corner should not be less than the 1.50-meter-high flat-topped flagpole on the system flags side; similar flag and flagpole can each vertical side of in venues both sides are on the sidelines of the midline at least 1 meter.

the goal area of ​​the artificial lawn Gate Stadium: both ends of the venue from the goalposts inside of 5.50 meters at the goal line, a 5.50 m long vertical line and the goal line to the inside of each painting, one end in contact with the goal line, the other end of the draw a connecting line parallel to the goal line, the region called these three lines and the goal line within the goal area.

the artificial lawn Gate Stadium penalty area: away from the goalposts the inside of 16.50 meters at the goal line at both ends of the venue, a 16.50 m long vertical line and the goal line to the inside of each painting, the upper end of phase with the goal line, the other end of the draw a connecting line parallel to the goal line areas within these three lines and the goal line is the penalty area. 11 meters at each of the vertical to the floor at the midpoint of the two goal line to make a clear mark, called the penalty spot. The penalty spot for the center, to 9.15 m radius, draw an arc outside the penalty area, called the penalty arc.

Stadium corner area of ​​artificial lawn Gate: crossing point to the sideline and the goal line for the dots, 1 meter radius, field painting a period of a quarter of an arc, arc region called the corner area.

The artificial lawn gate the stadium goal: The goal should be located in the center of each goal line, and an equal distance from two distance of 7.32 meters, with both sides of the corner flag, along the upright post with a crossbar away from a level of 2.44 meters above the ground connected components, To ensure safety, whether it is a fixed goal or removable goal must be stable fixed presence on the ground. Doorpost and the width and thickness of the crosspiece should be symmetrically equal, should not exceed 12 cm. The net is attached behind the goal post and crossbar and the ground. Net should be properly sprung and to full activities goalkeeper space.

New artificial lawn gateball court in now standard door stadium size chart based on the column of a circle with a radius r 2M r 5M circle, forming a radius r 2M round pillars and an inner diameter r 3M annular area (in order to increase the technical difficulty of the radius of the column can be set as r 3M, ring outside the arc followed pushed to r 6M); point to the column axis, vertical four game line draw 4 perpendicular bisector of the stadium is divided into four ring outside the zone; four corners to angle vertex of a circle with radius r 1.5M arcs tangent edges to form four sectors protected areas. So gateball court divided into a column district, an annular zone, four ring outside the area, the four corners of protected areas, a total of 10 regions.

How to adapt to the artificial grass to become the biggest problem faced by the German team

The German team, the most talked about not Hiddink and his Russian team, but Moss Kolwezi Day Nicky Stadium piece of artificial grass. German internationals are accustomed to playing on natural turf this very strange, even the battle-hardened captain Michael Ballack said: "I do not have the artificial grass playing football, in the above, the number of training rarely."

How to adapt to the artificial grass to become the biggest problem faced by the German team coach Joachim Loew admitted: "Of course, this is a big change, we will have to adapt to this environment with the fastest speed." German team "moved" Mainz Bruch Road Stadium, where the artificial grass to find the state Tuesday afternoon, they kicked Mainz amateur team game "secret warm-up match to find the feeling.

This is not an official warm-up match, every 10 minutes or so, Loew will stop the match, according to the field in a timely manner and make new deployment. In order to adequately simulate the atmosphere of the Moscow decisive battle, Lufkin also require more turf watering, because he clearly when the Russian team will use this means to accelerate the running speed of the ball, so that the German team is difficult to control the strike. Whether it is the main, or substitute, get the opportunity to adapt to the venue.

However, just as the United States because of Mainz coach Tu Heer said: "only three days to adapt to this change is very difficult." Warm-up match, the German team pass the ball success rate is not too high, slippery venues, the ball becomes quickly. Time with Barak pass to Podolski, although known for its speed, Polti still could not catch up with the ball, let sidelines Loew looked straight frown, but his attitude is very firm: We must adapt to this change! "At the same time, he also pointed out that the German team to solve the two problems must be solved: both offensively and defensively, we must pursue passing accuracy as well as good control of the ball impact point."

Barak is still winning hand

33-year-old Barak will not forget, when he was able to lay a core position in the German team, the perfect performance of the two rounds of the 2002 World Cup qualifying play-offs against Ukraine contributed, and now he is facing from the former Soviet Union team severe test, and this time, he may not want to relive the experience of a playoff. Russia coach Guus Hiddink, Ballack is no stranger.

Chelsea during the two have worked for months to this battle, they did little to fight the "war of words". Last week, Hiddink suddenly appeared in London, was kind enough to Barak had a conversation. Barak explained: "This is a time not planned talks, nothing special and we talk about some chores, of course, due to Saturday's game, we have each other to open a bit of a joke, and we all know this the importance of the game. "Hiddink's coaching ability, Barak knows it, he is definitely a fox-like cunning coach.

Completely different quality artificial turf material with plastic track material

the quality and longevity of the artificial turf depends primarily on its production process and the quality of the grass fibers, poor quality grass fiber is easy to become brittle, ultraviolet radiation, temperature change, acid rain and other environmental weathering, the industry called "fibrosis" after stampede easily become powdery after exercise by inhaled will cause coughing, harmful to health. Primary school students inhalation lawn "hairy" product is inferior lawn fibrosis. Professor Chen reminded, buy artificial turf must choose a certified high-quality product, do not blindly covet cheap penny wise and pound foolish.

Completely different quality artificial turf material with plastic track material, polypropylene, nylon, polyethylene, are non-toxic materials, no effect on the movement of health through environmental certification lawn, even reached the end of its life, can also be processed by combustion and does not produce harmful gas, can also be used as road administrative works foundation filler waste utilization. Compared with natural turf with environmental wear-resistant, weatherproof to laying many convenient maintenance, security, economic and practical advantages.

Artificial turf has these advantages and features, the reporter learned that, in addition to the Nanjing Normal University and a few other schools have also cited proud of the natural lawn, about 95% of the institutions use from the artificial turf to Ning tertiary institutions . In addition to the university campus, National Fitness Ninghai Middle School, Zhujiang Road Primary Suojin Village Elementary schools and many cell site, "Shop and the artificial turf. But the reporter also learned that this industry is only 10 years to enter the domestic high-tech, not yet introduced a unified quality standards, the quality department can not its quality supervision.

Jiangsu production and sales of artificial turf to create artificial turf Limited chief engineer Li Jian, the research and development of artificial turf has entered the third generation, the turf performance has been very close to the natural grass, and because of the high the lawn cost-effective domestic product, foreign is slowly losing the advantages of the brand and gradually fade out of the mainstream domestic market. Right now the detection and evaluation of the Jiangsu create a company involved in the development of artificial turf standard has been drafted on to be promulgated after the approval of the national commission. The experts called for an early set the standards, effective supervision, to prevent the occurrence of of inferior lawn "wounding".

Give you a good synthetic turf tennis courts provide a long-term movement fun

Give you a good synthetic turf tennis courts provide a long-term movement fun, but the prerequisite for the rational design, in line with the actual situation, material and construction quality assurance.

Provisions in the the the tennis competition rules promulgated by the International Tennis Federation and the National Sports Commission, a the standard synthetic turf tennis courts covers an area of ​​not less than 36.58 meters (length) × 18.29 m (W), this size is also a standard tennis court surrounded Weidang net ground nets or indoor architectural interior dimensions. The standard in this area, effectively doubles venue size: 23.774 m (length) × 10.973 m (W), should remain free room for each end of the line after not less than 6.40 meters, each edge should stay free room for not less than 3.66 meters. Install the net post in the center of the pitch, measured at the center of the two columns, column spacing is 12.80 meters, the top of the net post from the ground plane is 1.07 meters, along the center of the net from the ground plane is 0.914 m.

My company has a professional experience of construction of various types of tennis courts, tennis venues around the world, we have the construction of various types of synthetic turf. Strict construction quality system and perfect after-sales service that you can rely on the tennis court to builders.

If it is connected to two or more than two tennis courts built parallel. The adjacent site distance between the edges is not less than 4.0 m. If indoor network end of the line outside over 6.40 m clear height of not less than 6.40 meters, indoor rooftop in the ball online empty the clear height of not less than 11.50 meters. Outdoor tennis courts the four weeks Weidang height is generally between 4 to 6 meters, depending on the stadium surroundings with the building height, may be appropriate to increase or decrease. Need to install lighting lighting tennis court, indoor roof lamps distribution over the outdoor tennis court and the end of the line on both sides should be social lamps. Outdoor stadium lights lamps should be set at more than 7.0 meters from the ground on both sides of the fence. Light towards the ground from the field on both sides of uniform irradiation. Lights and the stadium used for different purposes, electric light technicians specialized design. Experience tells us that the average illumination of every piece of synthetic turf tennis court lighting should be between 280lux ~ 1200lux.

the artificial lawn fiber tensile strength as high as possible?

the artificial lawn fiber tensile strength as high as possible?

Friends do not know much about a lot of artificial lawn, tensile strength, the stronger the better, procurement grass fiber has become important to determine the basis, in fact, there is there is a lot of misunderstanding.

This common but less accurate idea of ​​misinterpretation of tensile strength detection, detection of artificial lawn tensile strength in the international standard on an artificial lawn products through analog movement cycle, the tensile strength of the product is reduced percentage. Lower basis of the standard values ​​of tensile strength, tensile strength decreased amplitude test on behalf of the grass fibers the better the quality, rather than the higher the quality the better is often said that some products tensile strength. Common sense, high tensile strength of the wire, and is not suitable for the sport. Therefore, the blind pursuit of high tensile strength and ignore to bring users the comfort and safety performance is the practice of putting the cart before the horse.

Venue on the artificial lawn fiber abrasion resistance (durability) depends on many parameters, and not rely solely on the tensile strength to decide.
