On July 27th, the "Qinshan No. 1" TBM used in the Qinshan Nuclear Power Auxiliary Steam Networking Project rolled off the production line in Tangxing Technology Trenchless Industrial Park, and will soon be put into interval tunnel construction.

Wu Tao, Secretary of the Party Group of Huainan Federation of Industry and Commerce and Deputy Director of the United Front Work Department of Huainan City, Zhang Youxian, Secretary of the Datong District Committee, Ming Guanlei, Deputy Secretary of the District Committee and District Mayor, Duan Chuanmin, Director of the Standing Committee of the District People's Congress, Zeng Jing, Deputy Secretary of the District Committee, Chen Yongqiang, Deputy Secretary of the District Political Consultative Conference Chairman, Wang Pan, Section Chief of Qinshan Nuclear Power Engineering Management Office , Wang Xingzhou, Nuclear Engineering Division Manager , Yue Xin, CNNC Consulting Project Director , Yan Su, Nuclear Industry Shaft Qinshan Tunnel Project Manager, etc. attended and witnessed the Tangxing Technology "Qinshan No. 1 TBM ceremony.

The project tunnel is passing through tuff formations mainly composed of III, IV, and V surrounding rocks. If the traditional artificial drilling and blasting operation method is used, the process quality is not easy to control, and the safety risk is extremely high. In order to ensure the safety and efficiency of tunnel construction, the R&D team of Tangxing Technology adheres to the design and manufacture concept of safety, environmental protection and efficiency, integrates advanced technology into the equipment, and successfully completes the design and manufacture of the TBM.

The TBM has an excavation diameter of 4 meters, a total equipment weight of 220 tons, and a total length of 72 meters. TBM heavy-duty cutter head, multi-section shield body, three-dimensional slag discharge system and variable support system are specially configured to meet the requirements of long-distance hard rock efficient tunneling.

Tangxing scientific and technological workers anchored on the goal. They developed and manufactured a batch of groundbreaking, foundational, and milestone products, and promoted Tangxing products are moving towards a higher and farther goal.
