地下构筑物的防水问题是建筑设计中的薄弱环节之一。它的优劣直接关系到厂房结构的使用年限和稳定性,而且也影响着设备的使用和工人操作条件。因此,近几年来有关单位根据防水工程存在的问题进行了一系列的调查和研究,取得了不少经验。在所调查的一些地下构筑物中,渗水漏水的情况是十分普遍的,某些工程的渗漏情况还相当严重,已为生产带来许多不 Waterproofing of underground structures is one of the weak links in architectural design. Its advantages and disadvantages are directly related to the service life and stability of the plant structure, but also affect the use of equipment and workers operating conditions. Therefore, in recent years, the relevant units have conducted a series of investigations and studies based on the problems existing in the waterproofing project, and have gained a lot of experience. In some of the underground structures under investigation, leakage of seepage water is very common. The leakage of certain projects is still quite serious, and many
