July twenty seventh，Applied to Qinshan Nuclear Power Auxiliary Steam Interconnection Project Tunnel Project“Qinshan No.1”TBMSuccessfully offline in Tangxing Science and Technology Trenchless Industrial Park，It will be put into the construction of the interval tunnel.。

Party Secretary of Huainan Federation of Industry and Commerce、Wu Tao, Vice Minister of United Front Work Department of Huainan City，Zhang Youxian, Secretary of Datong District Party Committee，Deputy Secretary of the District Committee、District chief Ming Guanlei，Duan Chuanmin, Director of the Standing Committee of the District People's Congress，Zeng Jing, Deputy Secretary of the District Committee，CPPCC Vice Chairman Chen Yongqiang，Wang Pan, Chief of Qinshan Nuclear Power Engineering Management Office，Wang Xingzhou, manager of nuclear engineering department of nuclear industry well and lane，Yue Xin, Project Director of China Nuclear Consulting，Yan Su, the project manager of Qinshan Tunnel in the nuclear industry, attended and witnessed Tangxing Science and Technology.“Qinshan No.1”TBMOffline ceremony。

The tunnel of the project is mainly composed ofIII、IV、VTuffaceous formation dominated by wall rock。If the traditional manual drilling and blasting method is used,，Process quality is not easy to control，Extremely high security risk。In order to ensure the safety of tunnel construction、High efficiency，Tangxing Technology R & D Team upholds safety、Environmental protection、Efficient design and manufacturing concept，Integrate advanced technology into equipment，Completed successfullyTBMDesign and manufacture of。

ThisTBMExcavation diameter 4m，Total weight of the equipment is 220 tons.，The total length is 72 meters。Targeted configurationTBMHeavy duty cutterhead，Multi-section shield，Three-dimensional slag-tapping system，Variable support system，Meet the requirements of long-distance hard rock high-efficiency tunneling。

Struggle in the summer，Live up to the time，Tangxing Science and Technology Workers Anchor Goals，Hurry up，Take advantage of the situation，Run out of acceleration，Draw a map of the scenic spot，R & D and manufacturing of a number of pioneering、Foundational、A landmark product，It has pushed Tangxing products to a higher level.、Move forward to a more distant goal。
