Application of cantilever roadheader in tunnel construction
View through CrossRef
Abstract
Cantilever roadheader is widely used in coal roadway engineering, but it is rarely used in urban subway tunnels. The underground boring tunnel in Guiyang City is selected as the object. The background and purpose of the cantilever roadheader, the construction technology and method, the advantages and disadvantages analysis and the construction optimization are selected to study its application in the underground karst tunnel. Studies have shown that the use of cantilever type roadheader can speed up construction progress, reduce surrounding rock disturbances, reduce safety risks and improve excavation quality, which is unmatched by traditional drilling and blasting construction.
