安全渡汛

2008年3月，為保證截流后(hou)庫(ku)區(qu)能安(an)全渡汛，保障庫(ku)區(qu)移民的生命和(he)(he)財產安(an)全。受國家電(dian)力(li)公司(si)貴(gui)陽勘(kan)測設(she)計研究院的委托，黃河(he)水(shui)(shui)(shui)文勘(kan)察測繪局(ju)承擔了(le)(le)沙沱水(shui)(shui)(shui)電(dian)站(zhan)庫(ku)區(qu)2008年汛期二十年一遇回水(shui)(shui)(shui)淹沒(mei)界樁的測量及(ji)埋(mai)設(she)工(gong)作。根據《水(shui)(shui)(shui)利(li)水(shui)(shui)(shui)電(dian)工(gong)程測量規范》SL197-97和(he)(he)設(she)計書的要求，黃河(he)水(shui)(shui)(shui)文勘(kan)察測繪局(ju)技(ji)術人員在國家電(dian)力(li)公司(si)貴(gui)陽勘(kan)測設(she)計研究院的協(xie)調幫助和(he)(he)沿(yan)河(he)、德江(jiang)縣移民局(ju)及(ji)當地鄉(xiang)（鎮(zhen)）、村組干部(bu)的積極配合下，順利(li)完成了(le)(le)庫(ku)區(qu)淹沒(mei)界樁的測設(she)工(gong)作，為沙沱水(shui)(shui)(shui)電(dian)站(zhan)08年安(an)全渡汛提供(gong)(gong)了(le)(le)有利(li)數據和(he)(he)保障。沙沱水(shui)(shui)(shui)電(dian)站(zhan)是國家“西電(dian)東送”工(gong)程的重要電(dian)源(yuan)點(dian)，2007年底(di)成功進(jin)行(xing)了(le)(le)大(da)江(jiang)截流。2008年以(yi)來，武警水(shui)(shui)(shui)電(dian)四支隊(dui)基礎(chu)處(chu)理項目部(bu)官兵們夜以(yi)繼日地對(dui)上下游截流圍堰進(jin)行(xing)堵水(shui)(shui)(shui)灌(guan)漿閉氣(qi)施工(gong)，確(que)保底(di)能正式轉入(ru)大(da)壩主體(ti)工(gong)程施工(gong)。然而，持(chi)續的雨雪(xue)冰凍使得工(gong)區(qu)水(shui)(shui)(shui)、電(dian)和(he)(he)物(wu)資供(gong)(gong)應全部(bu)中斷，圍堰閉氣(qi)施工(gong)也被迫停止。

電(dian)站建設的環節絲(si)絲(si)相扣，工(gong)期絕不(bu)允(yun)許(xu)隨(sui)意(yi)拖(tuo)延，否則，汛期到來(lai)，可(ke)能造成難(nan)以估量的損失。面對(dui)生產、生活上的困難(nan)，項目部黨委“一班人”身先(xian)士(shi)卒(zu)、沉著應戰，打響了“大干二月戰雪災，閉(bi)氣固堤搶工(gong)期”的攻堅戰。

通過分析施工形勢，項(xiang)目(mu)部(bu)提出了停(ting)(ting)電不停(ting)(ting)工、備戰(zhan)搶工期的(de)應對思路。在交通不暢的(de)情(qing)況(kuang)下，項(xiang)目(mu)部(bu)主任聶國旺帶(dai)領官兵(bing)冒雪步行(xing)(xing)20多公(gong)里購買了手套、儲水罐等(deng)生產(chan)生活(huo)必需品。在臨(lin)(lin)時電源未供電前，項(xiang)目(mu)部(bu)積極組織官兵(bing)維修(xiu)機械設備、準(zhun)備施工材料。工區臨(lin)(lin)時電源恢(hui)復供電后，項(xiang)目(mu)部(bu)立即組織官兵(bing)恢(hui)復生產(chan)，實行(xing)(xing)晝夜兩班倒施工，全體(ti)人員(yuan)吃住在施工一線(xian)。
