簡介

紅花爾基水(shui)(shui)利樞紐工(gong)程(cheng)是(shi)內(nei)蒙古自治(zhi)區“十五”期間水(shui)(shui)資源開發項目，位于呼倫(lun)貝爾市鄂溫克(ke)旗(qi)境內(nei)，是(shi)伊敏河上唯一的控制(zhi)性樞紐工(gong)程(cheng)。工(gong)程(cheng)總庫容3.2億(yi)立方米，規模為大(da)Ⅱ型。工(gong)程(cheng)由大(da)壩、非常(chang)溢洪道(dao)、泄洪導流(liu)洞、工(gong)業供水(shui)(shui)洞、水(shui)(shui)電站等組(zu)成(cheng)，以供水(shui)(shui)、防洪為主，兼顧防凌、灌溉(gai)、發電、旅游等功(gong)能(neng)。

參(can)建各方(fang)在(zai)施工之(zhi)初就本著(zhu)“科學管理、創(chuang)造精品”的(de)原則(ze)，制定(ding)創(chuang)優規(gui)劃，且通力(li)合作(zuo)嚴(yan)格落實(shi)規(gui)劃要(yao)求，最終打(da)造了這個“管理規(gui)范(fan)、施工先進(jin)、設計(ji)優秀(xiu)、質量優良、運行(xing)可靠、效益顯(xian)著(zhu)”的(de)精品工程。
