October 17-The "Shenshan No. 7" Double Shield TBM, developed by CREG, has successfully completed factory acceptance and will be deployed on the Shenshan Cooperation Zone Water Diversion Project, supporting the integrated allocation of water resources between Huizhou and Shenzhen.
The water diversion project draws water from the Baipenzhu Reservoir in Huizhou and conveys it via tunnel to the Shenshan Cooperation Zone. The "Shenshan No. 7" TBM will launch from the No. 1 Distribution Pool and bore toward the intake of Baipenzhu Reservoir, covering a drive length of over 10 kilometers. The alignment traverses complex geological conditions and will pass beneath the Yongguan Expressway, the upper reservoir of Da'an River, and Baima River — key infrastructure and water bodies along the route.
With an excavation diameter of 7 meters, the "Shenshan No. 7" TBM has been specially reinforced by CREG's design team across multiple dimensions to ensure safe and efficient long-distance hard rock boring, enhancing the machine's adaptability and reliability under complex geological conditions.
Once completed, the project will address domestic, industrial and ecological water demand for the medium- and long-term development of the Shenshan Special Cooperation Zone, strengthen urban development resilience, and carry significant importance for the high-quality development of the zone.
