接触网过渡施工技术

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。

Transitional Construction Technologies of Overhead Contact Line

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 trac...
