Tunnel engineering is an important part of transportation, energy, water conservancy and other infrastructure construction, and its construction efficiency directly affects the engineering progress and cost. The traditional drilling and blasting method has problems such as large amount of

With the improvement of science, technology, and economic conditions, the level of mechanization in tunnel construction in China continues to rise. In tunnel construction, the development of fully mechanized construction is a new direction for future tunnel construction, using fully mechanized

Taking the III. and IV. grade surrounding rock construction section of Loushan Tunnel in Xinbin County, Fushun City, Liaoning Province as an example, mechanized supporting construction is carried out on the tunnel construction section. The design of the construction technology and the development

In view of the fact that the length of the hydraulic telescopic parallel boom of the traditional double-arm rock drilling rig can not meet the construction requirements of different excavation methods of large-section tunnels and is prone to the phenomenon of stuck drilling, and at the same time
