Research on Excavation Construction Technology of Cantilever Roadheader in Hydraulic Tunnel
The total length of the three sections of the Hutuo River Connection Project on the Wanjiazhai Yellow River South Main Line is 8.27 km.Each construction site is located within a 200-meter radius of residential areas,the rock layers intersect the tunnel axis at a small angle,predominantly displaying a horizontal thin-layer structure.To avoid construction interference and reduce the occurrence of adverse geological disasters such as collapses mud gushing and water gushing,the tunnel excavation strategy has been revised.This article mainly elaborates on the ex-cavation construction technologies and control measures of cantilever roadheaders.The use of cantilever roadheader instead of traditional drilling and blasting methods ensures construction safety,accelerates construction progress,and reduces project costs.The use of cantilever tunneling machines instead of traditional drilling and blasting methods ensures construction safety,accelerates construction progress,and reduces project costs.
