500kV高压线下钻孔桩施工技术

On drilling pile construction technique under 500 kV high-voltage wire

以永定新河特大桥工程为例,从技术方案方面和设备配备方面介绍了如何近距离在500 kV高压线下安全快速进行钻孔桩施工技术,并阐述了相应的质量检查方法和安全保证措施,经实践取得了良好的经济效益。

Taking the super-large bridge on Yongding New river as the example,the paper introduces the ways of how to undertake the drilling pile technique under 500 kV high-voltage wire safely and quickly from the technical scheme and the equipment facilities,illustrates the respective quality checking methods and the safety guarantee measures,and achieves better economic benefits in practice.
