The national teams of cross-country skiing, Nordic two, and biathlon will go to the ski resort for professional training in mid-April.

    The world's first use of the original civil air defense room reconstruction and expansion, the project scale, technical difficulty are the world's leading level

    According to Liu Yijun, director of the Ice Sports Center of Jilin City, the Beishan Four Seasons Cross-country Ski Resort is the world's first world-class project using the original civil defense caverns. The total construction area is 25,244 square meters and the total use area is 19,425 square meters. The extension meter is 1.8 km.

    The project is divided into two phases. The first phase includes 1308 meters of indoor snow roads, 1616 meters of outdoor snow roads, and about 3,000 square meters of athletes' departure hall. The effective height of the indoor track is 4 meters, the maximum slope is 8 degrees, and the overall line is 1 /3 Uphill, 1/3 downhill, 1/3 flat slope, the difference between the lowest point and the highest point is 21.3 meters. In addition, the indoor snowway consists of a shooting range and a penalty circle. The length of the shooting range is 65 meters and the width is 12.75 meters. The total area is 830 square meters. The length of the penalty circle is 53 meters and the width is 30 meters. The total area is 1590 square meters. Meter. The indoor snow track is equipped with a u-shaped track, mainly for professional skiers to use ski skills.
The second phase of the project includes indoor 500m viewing trails, 1,500 square meters of four seasons ice and snow experience pavilion and other supporting facilities, as well as athlete apartments.

    Mingxing provides a complete distributed snowmaking system, with a constant temperature of -6 °C in the cave, successfully creating a model of low-altitude snowmaking in the world.

    The connection point between the indoor snow lane and the outdoor snow lane in the departure hall of the ski resort is divided into two upper and lower floors. The basement of the departure hall consists of a reception hall, a refrigerating machine room, a transformer room, and an air-conditioning room. The reception hall is specially for trainers and visitors. The refrigeration room is the heart of the entire indoor snowway. It is specially designed to replace the traditional snowmaking technology with the sixth generation of “indoor distributed snowmaking system” independently developed by ES Ice and Snow. To achieve simulated natural snowfall, the snow conditions have reached the world-class professional skiing standards, ensuring that the indoor track maintains a constant temperature of -6 °C throughout the year, providing the best snow quality and venue for the athletes, and successfully creating the world's lowest snowfall. Create a model of low-altitude snowmaking in the world and help 2022 Beijing Winter Olympics!

    The variable electric machine room guarantees the power of the departure hall and provides power guarantee for the refrigerating machine room; the whole departure hall does not need heating, and the waste heat of the refrigerating machine room is heated by the air-conditioned machine room to heat the whole hall, so that it can reach the comfortable temperature of the human body. At the end of 2018, the State Sports General Administration sent an expert group to the scene to inspect the refrigeration, snowmaking and operation of the snow field, and highly praised and fully recognized the overall construction of the project.

    On the ground floor of the departure hall, there is a departure ski resort, a monitoring machine room and a snow-covered garage. The starting snow field connects the indoor snow road with the outdoor snow road, the floor is equipped with a cooling pipe, and there is an air conditioning unit above the air to ensure that the snow of the departure snow field meets the off-road requirement; there are 277 cameras in the indoor snow road, all connected with the monitoring machine room, monitoring The real-time situation of professional athletes trained in indoor snow trails and whether there is any injury during training can be called “outdoor eyes”; the width of the snow-covered garage door is 4 meters, ensuring that the snow-pressing car has a fixed stop, not Affect professional athlete training. It is reported that the snow trucks are all imported from Germany by environmentally friendly vehicles. Through the continuous cooling of the indoor professional snow roads, the snow snow trucks are used to complete the laying and compaction of all the bottom snow of the professional snow roads to meet the national team training standards.

    According to Feng Yuxin, the project investor and general manager of Wentou Jilin Sports Industry Investment Development Co., Ltd.: “The project was designed with the safety and comfort of the athletes in mind. The minimum turning radius of the snow road is 9 meters, ensuring that they are not Injured; professional snowy roads are equipped with professional facilities such as fire protection, fresh air, dehumidification, and snow making, which are much higher than European design standards; and the design of the shooting range and penalty circle ensures that athletes can reach actual combat training conditions."

    Prepare for the Beijing Winter Olympic National Cross Country Skiing Team Training Base, both professional and civilian

    Jilin Beishan Four Seasons Cross-country Ski Resort has 4 professional snow trails inside, which can accommodate 500 people at the same time. The trial operation began in early 2019. The professional cross-country ski team in Jilin City was invited to carry out the trial-slip training. The coaches and athletes were very satisfied with the snow quality, temperature, humidity, slope, camber and lighting on the track. They thought it was very close to the winter outdoor nature. snow Road. In January, in the winter camp organized by the State Sports General Administration, nearly 400 primary school students had experienced indoor skiing on the track, and the response was enthusiastic.

    The project is a key project of the State Sports General Administration to prepare for the Beijing 2022 Winter Olympics.
