超高压线下城市轨道交通现浇梁施工安全防护体系浅析

Construction Security System of Urban Rail Transit Cast-in-Site Beam of Ultra-High-Voltage Power Lines

我国城市基础设施建设处于大规模、高速度发展阶段,现浇桥梁在城市轨道交通建设中应用已很广泛,但施工过程中常会遇到超高压线路障碍影响,极大地增加了施工难度及安全风险,甚至无法施工。论文通过工程实例,分析采用合理、安全的防护体系对超高压线下桥梁施工加以防护,可以解决迁改周期长而导致工程延期的难题。

China＇s urban infrastructure construction in the large-scale, high speed development stage, cast-in-place bridge in urban rail transit construction is widely applied, but ultra-high voltage circuitry obstacles may happen in the construction process, it greatly increases the difficulty of construction and security risks, and even lead to can＇t construction. This paper taking an project example to analyze that adopting reasonable and safe protection system to protect the bridge construction under the ultra-high voltage power lines, can solve engineering problem of delay caused by moving change cycle is long.
