由于许多人防地下室工程长期置于地下水的侵害之下,特别是工程往往受到地形条件的限制,地下水很难降到工程底板标高以下。因此,地下水对人防地下室工程的危害作用是相当大的。做好相应的人防地下室防水工程的质量控制至关重要。 Because many civil defense basement projects have been exposed to groundwater for a long period of time, and in particular, engineering is often limited by topographical conditions, groundwater can hardly drop below the elevation of the project floor. Therefore, the harmful effect of groundwater on the civil air defense basement project is considerable. It is very important to do a good job of quality control of the basement waterproofing project.
