Mechanization of tunnel construction has become an important direction for the development of tunnel construction． Based on the construction of Dading Tunnel of Zhu-Zhao High-speed Ｒailway，the characteristics of mechanized tooling equipment involved in the standardized process of tunnel

Inheriting the tradition, combined with the actual situation, on the basis of enriching and improving the "valveless" pneumatic rock drill mechanical simulation concept, the "three control" design concept is supplemented; In terms of structure, the implementation of one modification, three

Rock drilling rig has a wide range of applications in inclined shaft tunnels, which uses the system to achieve automatic control, which can greatly improve the efficiency and safety of tunnel construction. In inclined shaft tunnel construction, rock drilling rigs are mainly used for drilling

The article compiles diameter data of 11 dual-control rock drills and 4 rear-control rock drills from Epiroc. The ratio range of stressed areas of the piston in return and power strokes is determined. Based on the analysis of ratio data, the article points out using the design variables based on 3-
