On June 2nd, a series of high-speed comprehensive test trains departed from Baoji South Station and headed west to Lanzhou West Railway Station, marking the entry of the Baolan High Speed ​​Rail (Baolan Passenger Line) into the Latong pilot phase, laying the foundation for the smooth opening of the entire line. Solid foundation.
According to the plan, Baolan High Speed ​​Rail will be open to traffic throughout the July 1st.
Baolan High Speed ​​Rail is the “last mile†of the Xulan High Speed ​​Rail in China’s high-speed rail network. It has a total length of 401 kilometers, a total investment of 56.45 billion yuan, and a design speed of 250 kilometers per hour. Construction began in October 2012, and the railway was built in the collapsible loess in western China. In the mountainous area, the bridge and tunnel accounted for 92.5% of the total.
The Baolan High Speed ​​Rail is connected to Xi'an-Baoji high-speed rail and Lanzhou-Xinjiang high-speed rail from the east and west respectively. It will be able to reach Urumqi directly from Xuzhou in the future and form a “high-speed wire roadâ€. The eastern, central and western high-speed rails in China are realized. Fully interoperable.
After Baolan High Speed ​​Rail opened, the time from Baoji to Lanzhou will be reduced from 6 hours to 2 hours, and Xi'an to Lanzhou will be shortened from 8 hours to 3 hours.
Today, the Lanzhou Railway Bureau officially announced the train schedule after the opening of the Baolan High Speed ​​Rail.
Bao Baolan high-speed rail:
The tallest bridge: the gully bridge, with a length of 779 meters and a bridge height of 55 meters, the main span continuous beam spans the Bohai Railway and is located in Dingxi City.
The longest bridge: the Shehe River Bridge, with a total length of 11392 meters, the main span (80+128+128+80) meters continuous spans the Weihe River, and the main span (72+120+120+72 meters) continuous beam spans the Tianshui River. Huangdao Avenue is located in Tianshui City.
The longest tunnel: Zhujiashan Tunnel, a total length of 14.949 kilometers, crossing the big god Liangshan, located in Qinshui County, Tianshui City.
The tunnel with the largest depth: the Bijiashan tunnel, with a total length of 14.751 kilometers and a maximum depth of 715 meters, is located in Dongji Town, Maiji District, Tianshui City, and passes through the middle and high mountains between Jiaochuangou and Qinlinggou.
The top four: the topography and landform along which the route passes, with the strongest collapsibility of loess, the most developed loess depression, the most serious and most developed geological disasters in the Loess Plateau, and along the Tianshui-Lanzhou seismic belt and the east-west direction. The Weihe seismic zone has a high frequency of activity and a high intensity, forming the "four most powerful" engineering geological environment characteristics.
