      Quest Winter Olympics Yanqing Division tube gallery project A 7.9 km tunnel, the water, electricity, telecommunications and other transmitted to the core area of the stadium - Quest Winter Olympics Yanqing Division tube Gallery engineering summer in July, 2022 Winter Olympics in Beijing Yanqing Division of infrastructure construction in full swing.Small sea Tuo south of the mountain, the National Alpine Ski Center, the National Center for two snowmobile sled race track and Yanqing Winter Games Village, Mountain News two non-competition venues are located here.Beijing 2022 Olympic Winter Games infrastructure projects totaling 31 projects, of which Division snowmaking water, domestic water, recycled water pipelines and electric power, telecommunications, cable television and other cable channels, is a division extending from the periphery of the core area of the reservoir to the stadium 7.9 km of underground pipe gallery.Recently, the reporter walked into the construction site of the construction is in full swing, visit Whats Pipe Gallery.Into Pipe Gallery Three main adit tunnel, I saw there are some pipe pieces on the ground, workers are busy.As the only construction unit Pipe Gallery installation of mechanical and electrical equipment, Railway First Lihui Song Jian, deputy party secretary told reporters: "Pipe Gallery is divided into two compartments by the structure of the board, on which the cabin compartment for the power and telecommunication cabin, set up high low voltage cables, wires, fiber optic communications and the like; the tank water tanks, water pipes laid parallel to two."Reporter noted, one side of the tunnel has been separated by the plate, the bracket is installed on the tank, to be erected weak systems, fire systems, electromechanical devices such as integrated devices, there are some on the lower cabin floor duct sheet, intermediate preform leaving the vehicle out of the travel path.And common urban underground pipe gallery different, this is the gallerys first Winter Olympics tube domestic mountains utility tunnel, the main tunnel entrance section elevation of 550 meters, 1,100 meters above sea outlet sections, vertical lift of 550 meters and a maximum gradient of 15%.Although the maximum gradient of up to 15% of all steel columns installed in accordance with design requirements must be perpendicular to the slope.For this purpose, before performing the processing of steel columns, steel columns skill first position is measured to determine the respective position of the steel column length, precise machining, to achieve the best use of the maximum.Design also requires a height error between the two adjacent steel column with layer holder shall not exceed 5 mm, while conventional handheld drill Artificial used because of a problem there will inevitably be errors.Project Department for this purpose the purchase of 10 sets of magnetic drill, accurate punching.After according to conventional procedures, only pipe rack plate finished pouring and achieve a certain strength, the power to carry out installation and construction of telecommunications equipment.Considering September 2020 to have water, electricity conditions of the target, the Ministry decided to advance the construction project planning, material stocks advance.The hardest part is crossing construction material transport.Erection water pipe gallery plate concrete pouring tanks applause scaffolding, when the longest stretch of 1 km.This causes scaffolding material can only reach the edge of the truck, and then manually secondary work surface to luck.Last winter, when the minimum temperature dropped to minus 27 degrees Celsius in just 45 days, participating in the construction project department staff will be more than 400 tons of steel columns, more than 300 tons bracket, and 15 tons of other materials delivered to the work surface to ensure on-site material supply.Pipe Gallery project is located in Beijing Songshan National Nature Reserve, fire and environmental requirements of high.To this end, the Ministry of Environmental Protection Project Participation in daily environmental education and fire prevention personnel before the site visit, fire lighters and other non-employees will bring up the hill, and urged everyone to work every day in front of the welding class construction garbage processing.Due to the geological conditions of Yanqing mountains, the destruction of vegetation recovery is extremely difficult.In order to protect the ecological environment, materials warehouse and processing plant project is not part of the construction site on the mountain, but several hundred thousand dollars invested at the foot lease for 11 acres of land for warehousing, materials to build warehouses and processing plants area.At the same time, vigorously promote green development, technology management efforts continue to strengthen efforts to promote resource conservation.Reporters learned that, as of now, the pipe rack construction tasks have been completed 55%, is expected in August this year, equipment installation, commissioning completed in late September, early next year will usher in a test match.Li Cheng Xu Fuping
