Tunneling Engineering

TBM (Tunnel Boring Machine), also known as a Hard Rock Tunnel Boring Machine, uses a rotating cutterhead on a circular cutting surface to compress and shear rock during construction. It picks up the excavated material (slag) through bucket teeth on the cutterhead, which is then transported backwards via a main conveyor belt and moved outside the tunnel using hauling trucks or a continuous conveyor belt.

In the field of TBM technology research and its application in China, Beijing Vibro has established a high reputation in hydraulic tunnel construction for water conservancy and hydropower engineering due to its early investments and long-term expertise. The company closely follows the global progress of TBM development and has cooperated extensively with leading international companies, including Robbins (USA), Herrenknecht (Germany), CMC (Italy), SELI (Italy), Philippe Holzmann (Germany), and Witt (Germany), promoting the worldwide use of TBM technology. The company has undertaken numerous major TBM projects both domestically and internationally. These include:
  • The Dahuofang Reservoir Water Supply Project in Liaoning, China
  • The Jinping Hydropower Station Diversion and Drainage Tunnel Project
  • The NY Hydropower Station Project in Pakistan
  • The Jilin Songyin Water Supply Project
  • The Yunding Tunnel Project in Malaysia
The tunnel diameters in these projects range from 7.2 meters to 12.4 meters, with a maximum construction tunnel length of 24.3 kilometers. These projects have set numerous records in China and internationally, earning awards such as the Luban Award, Dayu Award, and Zhan Tianyou Award, along with multiple provincial and ministerial scientific and technological progress awards.
On November 22, 2002, the State Economic and Trade Commission and the Ministry of Finance of China entrusted Beijing Vibro with a special research contract under the “15th Five-Year Plan” for TBM technology and equipment development. BJ Vibro collaborated with Wuhan University to carry out geological exploration, design prediction, and TBM equipment development for the South-to-North Water Diversion Project. The company has also participated in technical and economic consultation meetings related to TBM engineering in water conservancy and hydropower, providing essential data for the advancement of TBM technology.
