当前,高层小区地下人防建筑设计中,排水设计非常重要,其中排水横干管和排出管的设计是重中之重。在该类管道的设计、安装以及输水过程中会遇到一系列的问题。设计人员设计出了多套方案以解决该类问题。其中,在人防地下室顶板以上设置覆土层和管道层是两种常用的方案。采用对比研究的方法,对它们进行介绍,然后结合经验,提出具有可操作性的建议。 At present, drainage design is very important in the design of underground civil air defense buildings in high-rise buildings. Among them, the design of drainage cross-over pipes and discharge pipes is the most important. There are a series of problems encountered in the design, installation and water conveyance of such pipelines. Designers have designed a number of programs to solve this type of problem. Among them, the overburden and pipeline layer above the civil air defense basement roof are two commonly used programs. Adopting the method of comparative study, introducing them, and then combining the experience, put forward the feasible suggestion.
