Why is the Great Wall Station of Beijing-Zhangjiakou High-speed Railway called an underground maze?

It is reported that the Beijing-Zhangjia High-speed Railway Great Wall Station is located at the foot of the Great Wall in the depths of Yanqing Mountain in Beijing. After being reported by the media, it was called an "underground maze" similar to high-speed railway station by netizens.

According to the report, the underground station of Beijing-Zhangjia high-speed railway Great Wall Station subverts "high-speed rail common sense". According to media reports, hundreds of meters along the No.2 inclined shaft, various trunk and branch tunnels extend in all directions. Water, electricity, ventilation and other pipelines are intertwined, and construction machinery and transport vehicles shuttle back and forth. However, the "big guy" on weekdays is not tall in the tunnel.

According to the person in charge of China Railway Construction, the semi-arch tunnel has a maximum span of 32.7 meters and a height of 19.5 meters, making it the largest single-arch tunnel in China. Although the new Badaling tunnel with a total length of 12.05438+0 km is not the longest in China, the Badaling Great Wall Station located in the tunnel is the first case in the history of high-speed rail construction.

It is reported that Daling Great Wall Station has a building area of 36,000 square meters and a total length of 470 meters. It has two platforms, two main lines and four tracks, and the track surface is 102 meters from the ground. At present, it is the largest underground station of high-speed railway in China. The station is divided into three underground structures from bottom to top, namely, platform floor, entrance floor and exit floor (equipment floor).

I hope the Great Wall Station will be completed as soon as possible!
