The survey and design technology of irrigation and water supply engineering with high lift, large flow and multi-stage pumping stations, represented by Jingtaichuan electric power pumping project, has been built in Gansu Province since the 1960s and 1970s to solve the land irrigation on both sides of the Yellow River in Central Gansu Province and solve the problems of survival, food and clothing and poverty caused by drought and water shortage in Gansu Province For irrigation project, Gansu Institute has successively completed the design of electric power pumping and irrigation projects, such as Jingtaichuan, Sanjiaocheng, Jinghui, xingbaozichuan Xicha, Gansu special part of Yanhuanding Yellow River lifting t-project, among which Jingtaichuan electric power irrigation project is the representative. Jingtaichuan electric power pumping irrigation project I is located in the central part of Gansu Province. The project is composed of Jingdian phase I project, Jingdian phase I project and Jingdian phase I project extending to Gansu Minqin water diversion project. It is a large-scale high lift, large flow and multi-stage electric water pumping irrigation project. The maximum water lifting height is 713 meters. There are 43 pumping stations with an installed capacity of 259700 kilowatts. The Yellow River is a famous muddy river, and there are many technical difficulties in engineering construction. Gansu Institute of energy conservation and consumption reduction measures in high lift irrigation area, head distribution of multi-stage pumping stations, inter stage matching of multi-stage pumping stations, erosion and wear of pumps, safety protection of equipment in case of power failure of pumping stations, design scheme of gentle slope and long pipeline, anti siltation of pump station forebay near desert canal in high lift irrigation area A series of technical innovations have been made in sand control measures of road sections, which has formed the technical advantages and characteristics of Gansu Institute in the high lift electric pumping irrigation project. After nearly 50 years of construction and operation, Jingdian project has become a model of domestic construction of high lift I project, and has become the "most in China" named by comprehensive evaluation. Since this century, in order to solve the urban and rural water difficulties in the arid areas represented by the central and Eastern Gansu Province, achieve the goal of poverty alleviation and consolidate the achievements in poverty alleviation, Gansu Province has invested and constructed a large number of pumping stations to raise water Gansu Institute has successively completed Jingyuan Shuangyong water supply project, North Huining water supply project in Taohe River Diversion period, and water supply project for urban and rural areas The design of Linxia Yellow River Diversion Project, Jishishan water diversion project, phase II supporting urban and rural water supply project of Taohe River Diversion Project, and water supply project for poverty alleviation and development of ecological immigrants in Central Gansu Province have solved many technical problems in the design and operation of water supply projects mainly composed of pumping stations and complex pipe networks, and the progress has enhanced the technical advantages of our company in the high lift water lifting project.
