既有线信号施工封锁的技术准备

Discussion on Technical Preparations of Signal Blocked for Construction on Existing Lines

既有线信号改造施工,要在短短几个小时的封锁时间内进行施工、试验、开通,顺利实现新旧设备的倒换,技术要求精,安全风险高,施工难度大,对铁路运输安全及效率影响极大。施工封锁前有效的技术准备,能够提前发现设计错误、施工错误以及为封锁顺利进行提供支持,确保信号施工封锁安全、正点开通。

For signal reconstruction of existing lines, it needs to fulfi ll construction, testing, commissioning and switching between new and existing equipment within few hours. So it is charactered with high technical requirements, high hazard, difficulties of construction and great effects on the railway transportation safety and effi ciency. The effi cient technical preparation before blocking for construction can fi nd errors in the design and construction early and provides the support for successful blocking to ensure the safety of construction blocking and commissioning on schedule.
