Sinorock® self drilling anchor bolt products are used in several tunneling projects, such as Beijing-Fuzhou High-speed Railway, Shanghai-Kunming High-speed Railway, Xi’an-Chengdu High-speed Railway.

Beijing-Fuzhou High-speed Railway

The Beijing-Fuzhou High-speed Railway begins at Bengbu station of the Beijing Shanghai High-speed Railway line, and continue through Hefei (Anhui province), Huangshan (Anhui province), Shangrao (Jiangxi provice), Wuyishan (Fujian province), Nanping (Fujian province) and Fuzhou (Fujian province).

The Fuzhou-Hefei railway connects with the Fuzhou-Xiamen High-speed Railway in the south and Hefei-Bengbu High-speed Railway in the north. It is another high-speed railway designed to run at least 250 km/h and with a two-lane electrified standard following Beijing-Tianjin, Wuhan-Guangzhou and Zhengzhou-Xi’an high-speed railways.

The railway is completed in 2014. Upon completion, the journey time from Beijing to Xiamen by bullet trains is shortened to 9 hours from the past 31.5 hours.

Shanghai-Kunming High-speed Railway

The Shanghai-Kunming High-speed Railway is a high-speed railway line partially under construction in China. It is part of the CRH’s (CRH is short for China railway high-speed) system of passenger dedicated lines, beginning in Shanghai and ending in Kunming. It will parallel much of the current Lower-speed Shanghai-Kunming Railway. It will also pass through the cities of Hangzhou and Changsha.

Currently, the only section of the Shanghai-Kunming passenger dedicated line in operation is the section from Shanghai to Hangzhou, known as the Shanghai-Hangzhou Passenger Railway. The Hangzhou-Changsha section is scheduled to open at the end of 2014.

Xi’an-Chengdu high-speed Railway

Xi’an-Chengdu high-speed railway is a dual-track, high-speed rail line, under construction in western China between Xi’an and Chengdu. It will run 510 km through Shaanxi and Sichuan provinces and will accommodate trains traveling at speeds up to 250 km/h. Travel time between the two provincial capitals will be reduced from 13 to less than 3 hours.

The project was approved by the State Development and Planning Commission in October 2010. Construction of the Sichuan section of the railway started on November 10, 2010, and of the Shaanxi section, on October 27, 2012. It is scheduled to be completed by 2015. The line will traverse the rugged Qinling and Daba Mountains and connect the Guanzhong Plains and the Sichuan Basin.
