2008年(nian)(nian)3月,為保證截流后(hou)庫(ku)區(qu)(qu)能安(an)全渡汛,保障庫(ku)區(qu)(qu)移(yi)民(min)的(de)(de)生命(ming)和(he)(he)財產安(an)全。受國(guo)家電(dian)(dian)力公(gong)司貴陽(yang)勘(kan)(kan)測(ce)(ce)設(she)計研究(jiu)院(yuan)的(de)(de)委(wei)托,黃(huang)河(he)水文勘(kan)(kan)察(cha)測(ce)(ce)繪(hui)局(ju)承擔了(le)(le)沙沱(tuo)水電(dian)(dian)站(zhan)庫(ku)區(qu)(qu)2008年(nian)(nian)汛期二十年(nian)(nian)一遇回水淹(yan)沒(mei)界(jie)樁的(de)(de)測(ce)(ce)量及埋設(she)工(gong)作。根據(ju)《水利水電(dian)(dian)工(gong)程測(ce)(ce)量規范》SL197-97和(he)(he)設(she)計書的(de)(de)要(yao)求(qiu),黃(huang)河(he)水文勘(kan)(kan)察(cha)測(ce)(ce)繪(hui)局(ju)技術人員在國(guo)家電(dian)(dian)力公(gong)司貴陽(yang)勘(kan)(kan)測(ce)(ce)設(she)計研究(jiu)院(yuan)的(de)(de)協調幫助和(he)(he)沿河(he)、德江(jiang)(jiang)縣移(yi)民(min)局(ju)及當地鄉(xiang)(鎮)、村組干(gan)部(bu)的(de)(de)積極配(pei)合下(xia)(xia),順利完成了(le)(le)庫(ku)區(qu)(qu)淹(yan)沒(mei)界(jie)樁的(de)(de)測(ce)(ce)設(she)工(gong)作,為沙沱(tuo)水電(dian)(dian)站(zhan)08年(nian)(nian)安(an)全渡汛提供了(le)(le)有利數據(ju)和(he)(he)保障。沙沱(tuo)水電(dian)(dian)站(zhan)是國(guo)家“西電(dian)(dian)東送”工(gong)程的(de)(de)重要(yao)電(dian)(dian)源點(dian),2007年(nian)(nian)底(di)(di)成功(gong)進行了(le)(le)大江(jiang)(jiang)截流。2008年(nian)(nian)以來(lai),武警水電(dian)(dian)四(si)支隊基礎(chu)處理項目部(bu)官兵們(men)夜以繼(ji)日(ri)地對上下(xia)(xia)游截流圍堰進行堵水灌(guan)漿閉氣(qi)施(shi)工(gong),確保底(di)(di)能正式轉(zhuan)入(ru)大壩主體工(gong)程施(shi)工(gong)。然而,持續的(de)(de)雨雪冰(bing)凍(dong)使得工(gong)區(qu)(qu)水、電(dian)(dian)和(he)(he)物資供應全部(bu)中斷,圍堰閉氣(qi)施(shi)工(gong)也被迫停止。
電站建設(she)的(de)環節絲絲相(xiang)扣,工期絕不允(yun)許(xu)隨意拖延(yan),否則(ze),汛期到來(lai),可能造成難以估量的(de)損失。面對生產、生活上的(de)困難,項目部黨委“一班人”身先(xian)士卒、沉著(zhu)應戰(zhan),打響(xiang)了“大干二(er)月戰(zhan)雪災,閉氣固(gu)堤搶工期”的(de)攻堅戰(zhan)。
通(tong)過分析施工(gong)(gong)(gong)形勢,項(xiang)目部(bu)提出了(le)停電(dian)(dian)不停工(gong)(gong)(gong)、備戰搶工(gong)(gong)(gong)期的應對思路(lu)。在交(jiao)通(tong)不暢的情況下,項(xiang)目部(bu)主任聶(nie)國旺(wang)帶(dai)領官(guan)兵冒(mao)雪步(bu)行20多公(gong)里(li)購買了(le)手套、儲水(shui)罐(guan)等生產生活必需品。在臨時電(dian)(dian)源(yuan)(yuan)未供(gong)電(dian)(dian)前(qian),項(xiang)目部(bu)積極(ji)組織(zhi)官(guan)兵維(wei)修(xiu)機械設備、準備施工(gong)(gong)(gong)材(cai)料(liao)。工(gong)(gong)(gong)區(qu)臨時電(dian)(dian)源(yuan)(yuan)恢復供(gong)電(dian)(dian)后,項(xiang)目部(bu)立即組織(zhi)官(guan)兵恢復生產,實行晝(zhou)夜兩班(ban)倒施工(gong)(gong)(gong),全(quan)體人員吃(chi)住在施工(gong)(gong)(gong)一線。
