摘要
针对疏解线、联络线在区间与正线接轨时,因条件限制无法设置安全线的情况,以新建宣绩铁路十里岩线路所为例,阐述特定地貌、地形限制下,对于无法设置安全线的线路所,信号工程设计中需要采取的安全防护措施;对比分析了"信号机外移"和"双红灯防护"2个方案,可为不设安全线的线路所的信号工程设计提供参考。
It is hard to set up a catch siding due to limited conditions in the section where an untwining line or a connecting line is connected to the main line.Taking Shiliyan block post on the newly-built Xuancheng-Jixi railway as an example,it is explored that the safety protection measures need to be taken in signal engineering design of the block post which cannot achieve the catch siding due to the constraints of specific landform and topography.Two solutions,moving signal toward outside and setting up double red lights for protection,are compared,providing reference for signal engineering design of other block posts without catch siding.
