220kV高压架空线下地连墙施工安全控制措施

Safety Management and Control Measures for Underground Wall Construction under 220kVHigh-voltage Overhead Line

南京地铁7号线某车站部分地下连续墙施工受到220kV架空高压线影响,本文主要从施工方案确定、机械设备的选择与改造、施工过程技术与质量管理、安全管控措施等方面,详细叙述邻近架空高压线下地连墙施工的关键控制要点。通过本次顺利实施地连墙施工的案例,为以后类似工况条件的地连墙施工提供成功的经验。

The construction of underground diaphragm wall in a station of Nanjing Metro Line 7 is affected by 220kV overhead high-voltage line.This paper mainly describes the key control points of underground diaphragm wall construction under adjacent overhead high-voltage line from the aspects of construction scheme determination,selection and transformation of mechanical equipment,construction process technology and quality management,safety control measures and so on.Through the successful implementation of the diaphragm wall construction case,it provides successful experience for the diaphragm wall construction under similar working conditions in the future.
