高速铁路接触网隧道预埋槽道全生命周期提前介入策略研究
摘要
Abstract
The tunnel catenary foundation is used to fix the catenary suspension column and additional wire supports and other equipment.It mainly comes in two forms,post-positioned chemical anchors and tunnel pre-embedded channels.The post-mounted chemical anchor bolt foundation is perforated and poured on the formed tunnel main body by the Fourth Electric Power Company construction unit.Because the internal structure of the tunnel cannot be detected,problems such as poor positioning accuracy and high construction difficulty exist,concealing defects and even endangering operation safety;The tunnel pre-embedded channels are simultaneously implemented and integrated by the construction unit in front of the station during the construction of the secondary lining of the tunnel,which not only ensures that the main structure of the tunnel is not twice damaged,but also meets the positioning accuracy of the catenary foundation.Starting from the perspective of early intervention by newly-built railway equipment management units,this paper focuses on studying the intervention priorities and intervention methods for the entire life cycle of tunnel pre-embedded channels,including design,construction,and inspection,so as to ensure the operation safety of the high-speed railway after its opening.关键词
