In order to speed up the excavation of the tunnel, since the start of construction, the construction party has adopted a combination of excavation methods that conform to the change of the surrounding rock grade of the tunnel during the construction process, and strictly controlled all aspects such as excavation, artillery firing, and slag discharge to ensure the smooth and orderly progress of construction. At the same time, the project construction team insists on emphasizing safety regulations and standard operations before the daily shift to ensure that each construction process meets the design requirements and ensures the smooth progress of construction.
