随着城市人口的增长及经济建设的发展,供水缺口日益严重。长距离、跨流域输水工程,尤其是管输工程迫切需要给排水工程设计人员综合给排水新技术、新材料、新设备,力争使工程实施后能做到安全供水、节能降耗、节省投资、自动化程度高、故障减 With the growth of the urban population and the development of economic construction, the water supply gap is becoming increasingly serious. The long-distance and inter-basin water conveyance projects, especially the pipeline transportation project, urgently require water supply and drainage engineering designers to integrate new water supply and drainage technologies, new materials and new equipment so as to ensure safe water supply, energy saving and consumption reduction after the implementation of the project and save investment High degree of automation, fault reduction
