摘要
为配合线路施工,接触网就涉及到过渡工程,接触网过渡工程依据线路改造的不同情况,采取区间曲内拨转、区间曲外拨转、区间双线同时拨转、车站过渡施工。区间上下行换边、新建网与既有网接火等方案合理组织,为配合轨道改建工程创造施工开通条件,并保证接触网改造施工顺利进行。
To coordinate with line constructions,transitional engineering is needed in the overhead contact line,which depends on the different situations of line transformations,adopting toggling inside the section,toggling outside the section,sectional double-line simultaneous toggling,and station transitional construction.Schemes of side change in up-and-down traffic and fire exchange between the newly-built lines and existing lines are rationally organized,so as to create construction operation conditions for track rebuilding projects,and ensure the smoothness of overhead contact line rebuilding construction.
