Jiehui Railway Baijiling Tunnel Import Entry Exit exceeds thousands of meters

On June 15th, the Guangdong Provincial Key Project under the 25th of China Railway's Twenty -five Bureau Jiehui Railway Control Project Baijiling Tunnel was imported by 1002.6 meters, which exceeded the kilometer mark, marking a new breakthrough in the project construction.

The positive line of the Jiehui Railway is 88.66 kilometers long. The line starts to Jieyang Station of Meishan Railway. China Railway Twenty -five bureaus undertake the construction tasks of 2 tunnels and 1 bridge of the railway. Among them, the Baijiling Tunnel with a length of 9.815 kilometers is the key control project.

According to Chen Pengzhou, the person in charge of the project of the 25th Bureau of the China Railway, the Baijiling Tunnel crosses the fracture belt, the terrain geology and hydrological weather conditions are complicated, and the geological structure is affected by the construction process. The safety risk is extremely high. Faced with complex geological conditions such as partial pressure, shallow burial, water riches, and broken intrusion bands, the project technical team responded to the deformation of the rock body by shortening the cycling ruler, timely adjusting the excavation work method, and advanced reinforcement to ensure the safety of the tunnel. In response to the subsequent tunnels, there will be more complex geology of fracture bands. The project builders have developed a special construction plan in advance to strengthen the surveillance measurement of tunnels and advance geological forecasting work, and make every effort to ensure the safety and quality of construction, and ensure the orderly progress of the project construction.

Up to now, the tunnel has a total of 1606.4 meters in the tunnel, and the exports have been excavated by 1606.4 meters. It is reported that one of the key projects in the Jiehui Railway as the "14th Five -Year Plan for the Comprehensive Transportation System of Guangdong Province" will be with the Beijing -Kowloon Railway, Guangmeishan Railway, Meishan Railway, Shanshan Railway, and Yingmei Railway. The connection of the Perisia Railway has become an important path for the exchanges of the domestic transportation and residents along the Jieyang Port. After the project is completed, it will further meet the needs of the Jieyang Port Area, improve the construction of interconnected intercity railway networks in eastern Guangdong, and promote the in -depth implementation of national strategies such as the Belt and Road and transportation powers. pole.
