摘　　要：排水系统是综合管廊工程不可缺少的部分,综合管廊内排水对象是管廊内渗漏水及管道检修放空水,其特点是水量小且不定、难以准确计算。目前综合管廊常规排水方式是通过集水坑收集并由潜污泵提升排出,存在设备多、排水点分散及施工难度较大等问题。针对上述问题并结合真空排水系统的优点,以实际工程为例,对常规排水系统和真空排水系统进行了多方面分析比较,研究表明真空排水系统既可满足综合管廊内排水要求,又可显著降低工程投资和施工难度,工程效果和经济效益良好。The drainage system is necessary in utility tunnel project. The drainage water of the utility tunnel consists of leakage water from the pipelines and emptying water produced during pipeline maintenance. The flow of drainage water is small, uncertain, and hard to calculate. At present, the conventional drainage is collected by sump pits and pumped out by submersible sewage pumps. The problem existed in the conventional drainage mode is necessary of more facilities, scattered drainage points and difficulty in construction. With regard to the issues above and the advantages of vacuum wastewater system, the contrast between vacuum and conventional drainage system has been conducted on basis of the real project. The results showed that vacuum drainage system not only met the drainage requirements of utility tunnel, but also reduced project investment and construction difficulty. Therefore, the favorable and economic benefit can be achieved when vacuum drainage system is applied to utility tunnel.
