长沙磁浮东延线信号系统接入既有线的改造方案
Renovation Plan for Connecting Signal System of Maglev East Extension Line to Existing Line in Changsha
摘要
Abstract
Traditional rail transit projects generally prepare for the conditions required for the extension line signal system to connect to the existing line from the beginning of the initial construction phase.However,accessing existing lines through the method of connection in specific sections faces more complex on-site conditions.In order to reliably and efficiently achieve the transformation of connecting the signal system to the existing line,while ensuring that the normal operation of the existing line is not affected during the transition period,a plan has been presented in this paper.Taking the East Extension Line Project of Changsha Metro Line S2 as an example(which is a maglev line),this paper analyzes the engineering difficulties as the starting point,and conducts research and analysis on project implementation timing,construction debugging difficulties,and coordination and cooperation ability.A renovation plan for connecting the signal system to existing lines has been proposed,providing a reference for future extension line renovation projects that adopt the method of connection in specific sections to access existing lines.关键词
