high-speed rail tunnel engineering Comparative Study on the Technical and Economic Performance of Two Rock Drilling Machinery in High-speed Rail Tunnel Engineering 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
rock drilling trolley Research and Application of Drilling Induction Device Based on Rock Drilling Trolley 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 engineering Research on Full-Section-Micro-Bench Rapid Conversion Construction Technology in Tunnel Engineering 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
Intelligent Research and Prospect of Intelligent Construction Technology of Xi-Yan High-speed Railway Tunnel 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
seawater corrosion Seawater Corrosion Conditions Analysis and Anti-Corrosion Scheme Design for Rock Drilling Jumbo 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
tunnel engineering Economic Comparative Analysis of Artificial Drilling and Blasting Method and Trolley Method in Tunnel Support Construction 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
