既有地铁车站电缆改造施工技术

Reconstruction Technology of Cable in Existing Metro Station

随着城市轨道交通建设的快速发展,网络化运行的地铁线路大量出现换乘车站,许多换乘车站是与早年建设的车站进行换乘,受当时的技术条件限制和现代建设标准的提高,实现既有车站与新建车站设备系统合理衔接难度很大。如何保证既有线的正常运行,对新线的建设施工存在很大的挑战。介绍北京地铁既有2号线车公庄站与新建6号线换乘引起的10 kV高压电缆路径改造施工。

Many new metro lines stations have transfer functions with early constructed stations, it is very difficult to achieve proper connection with existing stations and new stations in term of the interface of equipment systems. How to ensure the regular operation of existing lines, there are big challenges for new lines construction. The paper introduces the 10 kV high-voltage cable line reconstruction of the existing Chegongzhuang station on Beijing metro line 2 for connection to transfer to new Line 6.
