Walking into the world's deepest high-speed railway station at the foot of the Great Wall
On December 30, 2019, the world's most advanced 350km / h intelligent high-speed railway, Beijing Zhangjiakou high speed railway, was put into operation. From 35km / h to 350km / h, it shows the glory of "dream building" for a century. The world's first intelligent EMU with a speed of 350 km / h, Fuxing, passes through the Badaling Great Wall 102 meters underground, giving people a magic sense of crossing history. It is located in Badaling Great Wall Station, the deepest and largest underground high-speed railway station in the world. A 6031 a 6031 high speed railway tunnel at the foot of the Great Wall, high speed railway station at the foot of the Great Wall Our reporter will show you today. A 6031 a 6031 amazing: building a high-speed railway station 102 meters underground a 6031 a 6031 if it is a miracle to build the great wall above Badaling in ancient times, then building a high-speed railway station under Badaling today is a modern creation.
Badaling Great Wall Station is located on the ground near the mountain. The building is in harmony with the Great Wall. Through the natural transition between the three-dimensional greening and the mountain, the forms are scattered and correspond with each other. The underground part of the Great Wall Station is hidden at the foot of the mountain. It is the only underground station among the 10 stations in the whole line. It is located under the guntiangou parking lot of Badaling scenic area, adjacent to the great wall of Badaling. The largest underground building is 41000 square meters, creating four "the most in China" and three "the first time" in China. The great wall of
Badaling was built in the 18th year of Hongzhi reign of the Ming Dynasty (1505 A.D.) for more than 80 years. It has a history of more than 500 years. It was called "the danger of the mediocrity is not in the pass but in Badaling". The mountains here are overlapping and the terrain is dangerous. It's not easy to dig roads and roads here. A 6031 a 6031 "Beijing Zhangjiakou high speed railway new Badaling tunnel has a total length of 12 kilometers, and Badaling Great Wall Station is also located in the tunnel. Badaling Great Wall Station is the most complex underground tunnel group station in China at present. Because the station is 102 meters underground, it is necessary to build not only three underground structures, but also 78 large and small caverns in the tunnel. There are 88 kinds of different construction sections, which makes the construction difficult. " Chen Bin, commander of the North China headquarters of China Railway fifth bureau group, said. How to protect the cultural relics and avoid the immovable cultural relics and historical relics in the process of construction? How to ensure that no harm will be caused to the core area of Badaling Great Wall world cultural heritage? How to protect the underground soil and water environment? One by one, the major construction problems were successfully solved by the builders with craftsman spirit, craftsman wisdom and craftsman courage.
acme: challenge many world-class problems
"this station has created many acme, with a maximum buried depth of 102 meters. It is the underground station of high-speed railway with the largest buried depth in China, the station with the largest number of main tunnels and the most complex underground excavation group in China, and the underground station of high-speed railway with the largest height for domestic passengers to enter and leave the station. The tunnel where the station is located is the largest underground railway tunnel with single arch span in China, and the excavation span is 32.7m. " Duan Shijun, manager of Beijing Zhangjiakou high speed railway project Department of China Railway fifth bureau group, said proudly. During the interview, Duan Shijun left a deep impression on the reporter. He came out from Yunnan Dashan and majored in civil engineering. In his mind, Dashan seems to have a kind of natural intimacy and familiarity.
in order to protect Badaling Great Wall and centenary Qinglongqiao station, the railway people used precise micro damage blasting technology, the vibration speed of operation can be reduced to 1.6mm per second, to meet the requirement of zero settlement of construction surface, each blasting is only equivalent to a little foot stamp on the Great Wall. A 6031 a 6031 fast: the coolest route to climb the Great Wall a 6031 a 6031 January 1, the first day of 2020, Ms. Liu and her family from Henan choose to take the Beijing Zhangjiakou high-speed rail train to Badaling Great Wall for the new year. "As soon as the ticket is released on December 28, 2019, I will get the ticket! I've been looking forward to this high-speed railway for a long time. Less than 20 minutes from Xizhimen to Badaling Great Wall, too fast! " Said Ms Liu excitedly. After the operation of the
Beijing Zhangjiakou high speed railway, it takes less than 20 minutes for passengers to take the Beijing Zhangjiakou high speed railway from Beijing North Station to Badaling Great Wall. However, how can passengers get to such a deep underground high-speed railway station?
in fact, passengers don't have to climb any stairs. Get off from the underground station, just take the "super long" elevator to the Great Wall scenic area. After the reporter's experience, he found that passengers need to leave the station in two sections after arriving. First, take the elevator to lift 20 meters from the platform to the exit passage, and then go out through the long escalator with 3 lengths of 84 meters and 42 meters of lifting height. The whole process takes 8 minutes. At the same time, the station also has a car type inclined vertical ladder for the disabled. When
arrives at the station, the passenger passes the real name system ticket verification, takes the escalator to the waiting hall after arriving at the security checkpoint, and takes three long escalators with a length of 80 meters and a lifting height of 42 meters to enter the station. The reporter takes this kind of long escalator to have a kind of feeling of "flying" to the sky. A 6031 a 6031 110 years later, the intelligent Beijing Zhangjiakou high-speed railway and the century old Beijing Zhangjiakou Railway meet here. The word "human" written by Zhan Tianyou with steel rails has evolved into the word "big". 47 minutes activate the century old time. Badaling Great Wall Station is like a bright pearl inlaid between the mountains, adding another beauty to the beautiful Badaling.
