Highway Tunnels

The construction of highway tunnels is an important part of transportation infrastructure development, and the construction technology directly affects the quality, safety, and efficiency of the project. With the continuous expansion of tunnel project scale and the increasing complexity of

This paper takes the tunnel designed by New Italian Tunneling Method in Georgia as the research object, and analyzes the effect of multi-functional drilling rig, multi-arm rock drilling trolley and wet spray manipulator on the use of large-scale machinery such as multi-purpose drilling rig

With the advancement of mechanized construction of highway tunnels, various new technologies and new equipment are gradually introduced into highway tunnel construction. This requires construction units to continuously improve their own mechanized construction levels of highway tunnels to ensure the

Based on the background of the highway tunnel under construction, this article expounds that the use of a fully computerized three-arm rock drilling jumbo (ZYS113) to excavate in the surrounding rock of grade IV of the tunnel not only ensures the excavation and blasting footage
