Discussion on overall layout and key technologies about water supply project from Songhua River to middle citys

吉林省中部城市引松供水工程属于大型引水工程,从第二松花江上丰满水库引水至中部地区,向长春市、四平市、辽源市等11个市(县、区)供水,同时退还和增加农业用水及河道生态用水,保障地下水合理开采,改善生态环境,文中主要就工程的总体布局及输水总干线中的关键技术作了简要的介绍。

Water supply project from Fengman reservoir of the second Songhua River to middle citys of Jilin province belongs to large-scale division project.Water supply range involves 11 cities(counties,regions) such as Changchun city,Siping city,Liaoyuan city,and so on.Furthermore,agricultural water and river ecological water are handed back and increased so that it couldensure the groundwater rational exploitation and improve the ecological environment.This paper briefly introduces the overalllayout of engineering and key technologies of water conveyance general main line.
