The traditional tunnel drilling and blasting excavation is carried out manually. With the diversification of construction means, mechanizing the tunnel with three-arm rock drilling trolley can effectively improve the working efficiency and make the construction progress faster. This paper discusses the contents of the three-arm drilling trolley in the excavation of the highway tunnel, and discusses its construction mode, mechanical equipment and construction organization to provide reference suggestions for realizing the rapid and efficient construction scheme.
