With the rapid development of science and technology in China, great changes have taken place in the construction technology of tunnels. "Mechanization, informatization and intelligence" has become the inevitable trend of future development. Combined with the application of multi-arm rock

A single-arm rock drilling jumbo rig is used to drill holes in Ganyue Road, Chongqing, and then the rock stratum is split by hydraulic fracturing machine, and then removed by excavator. Large-diameter drilling increases the drilling tool loss of single-arm rock drilling jumbo.

For development of large equipment，such as drill jumbos，digitalization and intelligence are the trends in future. In order to clarify the research direction of the self-developed drill jumbo，combined with the current status of the drill jumbos applied in China's underground mine，where the drilling

The three-arm rock drill trolley is an important large machinery and equipment in the tunnel excavation, and its remarkable environmental protection, high eff iciency and safety features make the trolley more and more widely used, especially indispensable in the construction of long tunnels

As a new type of tunnel construction tool，the three-arm drilling rig is widely used in excavation，anchor construction and auxiliary operation of highway，railway tunnel，underground cavern excavation and other large section construction projects. This paper mainly combines the engineering practice

Through the analysis of the mechanism of small excavator and rock drill, the advantages and disadvantages of the two and their correlation degree are found.Adding various auxiliary tools on the excavator can not only expand the application scope of the excavator, but also adapt to
