Tunnel construction often encounters complex geological conditions. Due to the changes in construction methods, it is necessary to frequently change the excavation trolley, which is easy to delay the construction progress, increase the cost and cause safety risk accidents. Based on this, this paper

This paper studies the intelligent construction technology of the Xi-Yan of the high-speed rail tunnel, analyzes the problems and challenges existing in the construction of the high-speed rail tunnel, introduces the application status of the intelligent tunnel construction technology, and puts

China's gold mines are mainly concentrated in Shandong's Jiaodong Peninsula, and its underground gold mines are affected by seawater corrosion, causing frequent failures and reduced service life of rock drilling jumbo, which significantly affects construction efficiency and production costs. As a

Since the reform and opening up, China's rail transportation has developed rapidly, especially in the fields of tunnels and underground engineering in recent years. With the construction of century old projects such as the Hong Kong Zhuhai Macao Bridge and the Shenzhen Zhongshan Expressway

Inheriting the tradition, combined with the actual situation, on the basis of enriching and improving the "valveless" pneumatic rock drill mechanical simulation concept, the "three control" design concept is supplemented; In terms of structure, the implementation of one modification, three

With the continuous improvement of the design and manufacturing technology of large-scale tunnel machinery and its intelligence, the large-scale mechanized construction technology of drill-and-blast tunnels is becoming more and more mature. In this paper, the fully computerized 3-arm rock drilling

Rock drilling rig has a wide range of applications in inclined shaft tunnels, which uses the system to achieve automatic control, which can greatly improve the efficiency and safety of tunnel construction. In inclined shaft tunnel construction, rock drilling rigs are mainly used for drilling

The article compiles diameter data of 11 dual-control rock drills and 4 rear-control rock drills from Epiroc. The ratio range of stressed areas of the piston in return and power strokes is determined. Based on the analysis of ratio data, the article points out using the design variables based on 3-
