铁路隧道二衬脱空原因及注浆补强对策分析
摘要
Abstract
With the rapid development of China's railway network construction,the number of tunnel projects has increased significantly.As a key measure for surrounding rock reinforcement,the quality of secondary lining has become increasingly prominent,posing a serious threat to the safety of railway operation.In this paper,through comprehensive inspection and in-depth investigation,it is found that defects such as secondary lining voids and voids are common in railway tunnels that have been opened and are about to be opened and operated,and the proportion of tunnel projects in railway projects under construction is significant,indicating that such problems will become more prominent.Through in-depth analysis of the causes of void and cavity of tunnel secondary lining,the key points of quality control are clarified.At the same time,the problems existing in the theoretical basis and construction technology of the current grouting treatment method are analyzed,and the corresponding improvement and improvement suggestions are put forward.The results show that:The source control of engineering quality and the reduction of defects are the most economical and effective way to rectify the defects of secondary lining,but it is difficult to completely avoid them.The problems of excessive rectification and lack of normative guidance are prominent.It is necessary to conduct in-depth research and introduce relevant policies,correctly understand the complexity and particularity of rectification,and seek more scientific and reasonable rectification strategies on the premise of ensuring quality and safety.The remediation of engineering defects is the key to quality management,and all those who are involved should attach great importance to it.The engineering quality supervision department should take it as the inspection point,strengthen the normative guidance,and ensure the scientificity,standardization and effectiveness of the rectification work.Surveying the application scope and optimization parameters of grouting from the aspects of design and analyzing the causes of defects and taking measures in the construction stage can realize the fundamental strategy of improving the quality and safety level of the project from the source,and provide strong support for the sustainable development of railway construction.关键词
