8月21日，工作人员在利用城市道路真空高速排水系统进行模拟试验。2．5分钟就能将300立方米的积水排净，排水速度可达到3—6立方米／秒，是普通排水系统的3—6倍；管道拥堵和系统瘫痪几乎不会发生；仅需要对道路进行“微创”手术即可完成系统的安装建设。由中国北车山东华腾环保科技有限公司研制的我国首套道路真空高速排水系统21日发布，这款真空排水系统主要解决的是城市下雨积水，特别是下凹式立交桥下积水的问题。目前，国内普遍采用的排水系统是重力式排水系统，主要依靠积水自身重力作用排水，排水动力远不如真空动力。一旦有淤泥、碎石等杂物，极易堵塞管道。新华社发（刘长龙 摄）     August 21，Staff in the use of urban road vacuum high-speed drainage system simulation test。2.5 minutes to 300 cubic meters of water exhaust net，Drainage rate can reach 3-6 cubic meters/seconds，Is common drainage system of 3-6 times；Pipeline jam and system paralysis almost won't happen；Only need to road for“Minimally invasive”Surgery can complete the installation of the system construction。By the China north car shandong China environmental protection science and technology co., LTD., who developed the country's first set of high-speed road vacuum drainage system 21 release，This type of vacuum drainage system is mainly to solve the urban rain water，Especially under the concave type overpass water problem。At present，Domestic widely adopted drainage system is gravity drainage system，Rely mainly on water its own gravity drainage，Drainage power than vacuum power。As soon as silt、Gravel etc sundry，Pipeline easily。The xinhua news agency hair（LiuChangLong perturbation）
