This project involves the construction of the Chengdu to Lanzhou Railway, specifically the Chengdu to Chuanzhusi section, located within Sichuan Province. The main line has a length of 275.8 kilometers and is designed for a speed of 200 km/h. The Chenglan Railway starts in Chengdu and passes through Shifang, Mianzhu, Anxian, Maoxian, Songpan, and ends in Chuanzhusi. In 2017, our company undertook the task of supplying 12.6 kilometers of sound barriers for this project.

Upon completion of the sound barrier installation, the previously noise-exceeding residential areas, schools, and other sensitive areas along the railway can meet the railway noise emission standards as well as the functional zone standards of the sensitive points.
