In the process of vigorously promoting the "Belt and Road" policy in my country, more and more engineering contracting companies have responded to the call of "going global" and participated in the competition in the international market. It has become a new normal for construction companies to

Taking a single-track tunnel of a plateau railway as the research background, the full-section with invert one-time excavation technology was studied in the weak surrounding rock section, which saved resources and avoided many problems caused by the secondary blasting of the traditional invert. The
