Xinjiang Tacheng Area Water Conservancy and Hydropower Investigation and Design Institute

结合托里县那仁苏供水工程两处取水点位置选择5种供水总布置方案进行比选,从河道生态环境要求、供水水量、工程投资、施工工期、施工难度及运行管理等方面考虑,方案五(下游取水点首部加压方案)具有管线总长度短、隧洞段短、施工难度小、工程一次性投资小,满足生态和远期需水要求,后期运行管理方便等优势。

The five water supply general layout schemes were compared in combination with the two water intake points of Narensu Water Supply Project in Torri County.Considering the ecological environment requirements of the river,water supply,project investment,construction period,construction difficulty and operation management,etc.,Scheme 5(Pressurizing the head of the downstream water intake)has the advantages of short total pipeline length,short tunnel section,low construction difficulty,and low investment,meeting ecological and long-term water requirements,and convenient operation and management in the later stage.
