南水北调河南受水区供水配套工程总体设计理念

General design concept of ancillary water supply works for water service area of Middle Route Project of South-to-North Water Diversion in Henan Province

南水北调河南省受水区供水配套工程涉及范围广,线路长短、供水目标、供水方式差异大,是一个庞大的系统工程。针对供水配套工程具体情况,论述了供水配套工程总体设计理念,重点提出了长距离、大流量、多目标及高扬程输水工程的布置设计思路;考虑了输水工程的设计流量、水位势能利用问题;确定了输水线路及输水方式及保证输水安全的措施,为供水工程设计提供参考。

The ancillary water supply works of Middle Route Project of South - to - North Water Diversion for water service area in Henan Province is of huge systematic engineering and characterized as wide range and large differences of water conveyance line length, water supply users and water supply modes. In the light of the concrete conditions, this paper presents the general design concept of the ancillary water supply works, especially the design idea of water conveyance line characterized by long distance, large discharge, multiple water users and high lift. The utilization way of design discharge and water - level potential energy is discussed, and the water conveyance line and mode as well as the safety ensuring measures for water conveyance are proposed.
