The miracle of the Super League in three days
On August 15th, there was a heavy rain in Dalian. The match between Dalian Ren and R&F that was originally scheduled to be held at the Dalian Sports Center that night was postponed to the next day, and the venue was changed to the base stadium.
In fact, on the 15th, the Base Stadium just undertook the match between Shenzhen Football Team and Luneng. The match between Dalian People and R&F was the third China Super League held in this venue within three days.
The heavy rain fell sharply and the Dalian Sports Center Stadium was unable to compete, but the base stadium had three matches in three days, which was a miracle. Recently, this newspaper walked into this base.
The base is located on the north side of Lingxi Road and the east side of Zhuqi Road in Ganjingzi District. The gate of the base is less than 300 meters away from the main entrance of Crowne Plaza Dalian where the 8 Super League teams are staying. That is to say, training and competition are here. In fact, the team can be reached in less than 10 minutes on foot, but there is a municipal road between the two, and the team still takes a team bus to get there.
The base has 23 football fields, 13 of which are standard natural grass fields, lined up in sequence along the slope, and the first field is the Chinese Super League venue that fans saw during the live broadcast.
There are spectator stands on the side of the podium and on the opposite side of the venue, but due to the need of closure, the stands opposite the podium are not open to the audience, and only a camera position is provided for the TV broadcast.
After going upstairs, you can directly enter this field that has passed the test of heavy rain and continuous competition. Although the first stage of the Super League has ended and the second stage has not yet begun, it still feels very exciting.
Tall turf and drainage system
The reporter asked the base staff, what made this venue accept three games in the Super League within three days? What made the venue after the heavy rain show no trace of water on the broadcast screen? The staff only said, "You can feel it yourself!"
The reporter touched the turf and found that it was not all real grass, but a mixture of natural grass and artificial grass. This is the secret.
In the center of the venue, the reporter met the staff from Shenzhen Jiameiyin Sports Engineering Technology Co., Ltd. The company undertook the construction and maintenance of two natural turf and two artificial turf in the base. Before the game began, they had to make up the field.
According to the company’s staff, the base uses the most advanced hybrid anchoring turf system in the world. The anchored hybrid grass is calculated and arranged by a computer program through precise potential calculations, and the automatic robotic arm system is controlled to uniformly distribute 20 million 20 cm tall grass fibers. With a spacing of 2 cm, they are implanted in a grid of 18 cm underground and 2 cm above the ground. And 20 million anchored grasses are equivalent to 20 million conduits, which drain rainwater to the underground drainage layer, which plays a role of rapid drainage. The site added to the anchored grass system has a water seepage capacity of more than 8 times that of natural turf.
The base staff said that during the construction of the base, a special construction plan was formulated for the rainy weather in Dalian. The drainage system was constructed with fish bones, and the drainage performance was more efficient than conventional. Among them, the main drainage pipe in the site was a double-wall corrugated pipe with a diameter of 200mm. Four pipelines are arranged along the entire circumference of the football field; the drainage branch pipe has a diameter of 110mm double-wall corrugated pipe, which is connected to the main drainage pipe and is arranged perpendicular to the main drainage pipe with a spacing of 5 meters. The surface of the football field is turtle-backed water, with a slope of 0.4% in the middle and low in the periphery, so there will be no water accumulation.
The reporter experienced the "highness" of the turf system and drainage system on the spot, while the staff of the base introduced the superb competition reception ability of the stadium from a scientific and practical perspective.
At the scene, the reporter found another point worthy of attention, which was a "turf line" that the lineman stepped on when he ran back and forth on the sidelines, that is, a slightly damaged foot line.
Zhang Xiaohuan, general manager of Jiameiyin, who was communicating with the base staff on the spot, took out a few artificial grass from his backpack and placed them at the intersection of the midline and the sideline that the linesman often stepped on during the running process. A line of different colors appears, especially where the center line and the side line meet. In order to increase the perception, we will weave this position." Zhang Xiaohuan said, "We started the construction of professional football fields ten years ago. And management. In order to maintain the turf of the base, we spent more than 20 million yuan to purchase a full set of international top equipment such as the anchored hybrid grass planter imported from Germany and other football fields, such as this Chinese Super League turf, referees or player tread lines At the time, we can use the anchored hybrid grass silk planting machine for on-site weaving and quickly maintain the site."
"There is no chance of passing by"
The Chinese Super League game field at the base is not large. From the reporter's field measurement, the distance from the sideline to the stands is only 5 meters. Therefore, during the live broadcast, everyone sees the bench position, usually only the head coach, or two more team doctors, while the others sit in the stands.
Through the middle passage under the podium, you can directly return to the function rooms under the stands. Four hours before the game, the staff must arrange the marking of the game field, the team’s changing room, the referee’s room, and the game supervision room. Then, these important places will enter the blue zone. All green zone personnel must contact Keep your distance and wear a mask.
Although the team’s locker room and referee’s room are very compact, they are all equipped in accordance with the Chinese Super League standard. For example, the table in the middle of the team’s locker room is equipped with various fruits and tactical boards for the coach to make tactical arrangements. It is a history worth engraving on the base.
After walking through the playing field and walking up the slope, the team emblem logo of Deepfoot and R&F appeared about 100 meters away. After passing through a piece of turf, two pieces of standard natural turf next to each other appeared in front of you, one of which was hanging around With a lot of eye-catching banners, such as "Enlighten the deep meaning, enter the perfect world", "Shenzhen GOAL is wonderful", "Love to fight to win", etc., this venue is the deep training ground, and next door is the R&F training ground.
The staff of the base told reporters that natural turf and artificial turf are built by multiple companies, two of which are from Shenzhen.
Shenzu and R&F club executives said that their training bases in Shenzhen and Guangzhou are also maintained by these two companies. “Even in Dalian, we feel like at home in terms of venues.” Shenzu executives said.
In the deep foot training ground, the reporter met seven or eight staff members who were performing maintenance under the scorching sun. The homemade forks in their hands were very special.
"We have specially made maintenance tools according to the characteristics of the turf. Before the team trains every day, we will carry out maintenance." A staff member who came to Dalian from Guangdong said, "We are also Green Zone personnel. Those who don’t have the team will come after they leave. We wanted to cheer for the hometown team on the spot, but we need safety. Although we are on the same field, we don’t even have a chance to pass by."
For these behind-the-scenes workers, the Dalian Division Organizing Committee spoke highly of them, “It is precisely with these professional maintenance teams that they work hard day and night and work meticulously to make the ‘stage’ in the rainstorm still colorful.”
