Briefly describe the general situation and geological structure of a tunnel project in a bid section of the Xi'an-Chengdu high-speed railway, select three-arm rock drilling trolley and other rock drilling machinery for the tunnel project of the bid section, and formulate the drilling and blasting

After excavation and blasting, tunnels constructed by drilling and blasting often have large over-excavation and difficult to control. In this regard, the impact of over-excavation on tunnel construction and the reasons for over-excavation are deeply analyzed, and combined with the existing

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

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

Mechanization of tunnel construction has become an important direction for the development of tunnel construction． Based on the construction of Dading Tunnel of Zhu-Zhao High-speed Ｒailway，the characteristics of mechanized tooling equipment involved in the standardized process of tunnel

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
