高速铁路盾构隧道接触网预埋槽道关键点设计研究

Design of Key Points of Pre-embedded Groove for Overhead Contact System in High Speed Railway Shield Tunnel

以某工程项目的盾构隧道为例,对盾构隧道接触网预埋槽道关键点进行研究,分析了盾构隧道特殊的衬砌结构对接触网预埋槽道平面布置及对接触悬挂下锚补偿装置的转向定滑轮安装的影响,提出了盾构隧道区段接触网预埋槽道布置的建议方案。

This paper reports the case design of key points of the pre-embedded groove for overhead contact system in an actual shield tunnel of a certain project under construction.It analyzes the impacts of special lining structure of shield tunnel on the layout of pre-embedded groove,and on the installation of turning fixed pulley of contact suspension anchor compensation device.A recommended scheme for the layout of pre-embedded groove for shield tunnel section contact network is proposed.
