The Shandong section of Zhengji High speed Railway starts from Jinan West Station of Beijing Shanghai High speed Railway and travels westward to Huaiyin District, Shizhong District, Changqing District of Economic South City, Qihe County of Dezhou City, Chiping County, Dongchangfu District, Yanggu County and Shen County of Liaocheng City, to the border between Shandong Province and Henan Province. The total length of the main line is 168.583 kilometers.

Several HZS180 concrete mixing plants produced by Fangyuan Group are effective on various sections of the railway line. Each equipment is equipped with more than ten powder tanks and adopts a spiral overlap method to increase the powder storage capacity, achieve the longest continuous production time, and maximize the production capacity of each unit.

The construction of Zhengji Railway is progressing in an orderly manner, with several sets of Fangyuan Group mixing equipment quietly standing on each section, forming a unique scenic line, which will undoubtedly make greater contributions to China's high-speed railway construction.

Since 2007, more than 1000 sets of mixing plants from Fangyuan Group have been used for high-speed rail construction.
