核电工程建造阶段的雨水防漏问题的处理

The Treatment for Protection against Rain & Water Leakage in Nuclear Power Engineering Construction Period

本文针对核电现场的实际建造情况,分析了目前工程各厂房在大雨、暴雨或台风引起的瞬时强降雨而导致漏水的主要原因。从厂房屋面的施工质量控制、孔洞封堵、预留口的设置、厂房内排水系统管道的施工、室内的防雨水淹措施的制定等方面,提出了适用于核电施工现场的各类管控措施,可以有效减少厂房内重要设备、电气仪控设备、阀门、电机等的被水淹现象,从而减小重要、关键设备的浸泡受潮损坏现象。工程防水措施的制定,对各个核电的施工及其他工程建造均有很强的借鉴意义;同时也可以促进主要关键部位施工及工艺系统安装的顺利进行。

Based on the construction, the paper analyzes the main causes of heavy rain as well as water leakage caused by heavy rain, storm or typhoon. In view of the quality control for the roof during building construction, hole plugging, reserved hole setting, plant drainage pipeline construction, indoor flood prevention measures and other aspects, the paper puts forward for the nuclear power construction site of various control measures, which can effectively reduce the flooded phenomenon of plant important equipment, electrical equipment, instrument control valves, motor, etc. , so as to reduce the soaking damp damage phenomenon of important and key equipment. The establishment of engineering water-proof measures is of great significance to the construction in various nuclear power plants and other projects, and can also promote the smooth construction of key parts and the installation of the process system.
