排壩基故障

沙坨電站(zhan)大壩10#壩段(duan)在開挖過程中(zhong)出現多個巖(yan)溶管道，涌(yong)(yong)水(shui)(shui)量很大，經原施工單(dan)位處理后，未能將漏水(shui)(shui)成功(gong)封堵，采用在壩體內埋(mai)設集(ji)水(shui)(shui)鋼盒加排(pai)水(shui)(shui)鋼管的(de)方式將涌(yong)(yong)水(shui)(shui)引至(zhi)基(ji)坑。涌(yong)(yong)水(shui)(shui)除大部分(fen)(fen)從引水(shui)(shui)鋼管排(pai)出外，另有一部分(fen)(fen)經混凝土(tu)與基(ji)巖(yan)接(jie)觸面(mian)涌(yong)(yong)出。緊靠(kao)縱向圍堰的(de)10#壩段(duan)必須(xu)在2008年主(zhu)汛(xun)期到來前澆筑到指定高(gao)程，10#壩段(duan)內外水(shui)(shui)位高(gao)差達18米(mi)，滲(shen)漏途徑短(duan)且集(ji)中(zhong)，涌(yong)(yong)水(shui)(shui)量達10000m3/h，業(ye)主(zhu)委托水(shui)(shui)電八局基(ji)礎分(fen)(fen)局對(dui)涌(yong)(yong)水(shui)(shui)進行封堵灌漿。

在堵漏(lou)的(de)(de)各項工作中技術方(fang)(fang)案(an)(an)的(de)(de)確(que)定(ding)無疑是(shi)重中之重。水(shui)頭高、滲徑短、工作面狹窄、溶(rong)蝕裂隙錯綜(zong)復雜、灌(guan)注(zhu)漿(jiang)液大量流失，造成堵漏(lou)目的(de)(de)難(nan)以實現，這是(shi)克(ke)服工程(cheng)難(nan)題的(de)(de)關(guan)鍵所在。接到工程(cheng)信息后，公司經營人員(yuan)全(quan)力配合(he)，及時做好咨詢服務，為最終施(shi)(shi)工方(fang)(fang)案(an)(an)的(de)(de)確(que)定(ding)提供了有力的(de)(de)支撐。經業主(zhu)、設計(ji)、監理、施(shi)(shi)工單(dan)位現場多(duo)次勘察(cha)、驗證(zheng)，在對(dui)多(duo)個(ge)方(fang)(fang)案(an)(an)的(de)(de)綜(zong)合(he)比較、施(shi)(shi)工參數反復調整(zheng)后最終確(que)定(ding)以查(cha)找涌(yong)(yong)水(shui)通道(dao)和封(feng)堵涌(yong)(yong)水(shui)相(xiang)結合(he)、封(feng)堵涌(yong)(yong)水(shui)采用模(mo)袋灌(guan)漿(jiang)和HK-9105油溶(rong)性聚氨酯化學灌(guan)漿(jiang)相(xiang)結合(he)的(de)(de)施(shi)(shi)工技術方(fang)(fang)案(an)(an)。

安全渡汛

2008年(nian)(nian)3月，為保證截流后庫區(qu)(qu)能安全渡汛(xun)，保障(zhang)庫區(qu)(qu)移民的生命和(he)(he)(he)財(cai)產(chan)安全。受國(guo)家電(dian)力公司貴(gui)陽勘(kan)測(ce)設計研究院(yuan)的委托，黃河(he)水(shui)文(wen)勘(kan)察測(ce)繪局(ju)(ju)承擔了沙沱(tuo)水(shui)電(dian)站庫區(qu)(qu)2008年(nian)(nian)汛(xun)期二十(shi)年(nian)(nian)一遇回水(shui)淹沒(mei)界樁的測(ce)量(liang)及埋設工(gong)作。根據《水(shui)利水(shui)電(dian)工(gong)程測(ce)量(liang)規范》SL197-97和(he)(he)(he)設計書(shu)的要求，黃河(he)水(shui)文(wen)勘(kan)察測(ce)繪局(ju)(ju)技術人(ren)員在國(guo)家電(dian)力公司貴(gui)陽勘(kan)測(ce)設計研究院(yuan)的協調(diao)幫(bang)助(zhu)和(he)(he)(he)沿河(he)、德江縣移民局(ju)(ju)及當地鄉（鎮）、村組干部(bu)(bu)(bu)的積極配合(he)下(xia)，順利完成了庫區(qu)(qu)淹沒(mei)界樁的測(ce)設工(gong)作，為沙沱(tuo)水(shui)電(dian)站08年(nian)(nian)安全渡汛(xun)提供了有利數據和(he)(he)(he)保障(zhang)。沙沱(tuo)水(shui)電(dian)站是國(guo)家“西(xi)電(dian)東送”工(gong)程的重(zhong)要電(dian)源點，2007年(nian)(nian)底成功(gong)進行(xing)了大(da)江截流。2008年(nian)(nian)以來，武警水(shui)電(dian)四支(zhi)隊基礎處理項目部(bu)(bu)(bu)官(guan)兵(bing)們夜以繼日(ri)地對(dui)上下(xia)游截流圍堰(yan)進行(xing)堵(du)水(shui)灌(guan)漿閉氣施(shi)工(gong)，確保底能正式轉入大(da)壩主(zhu)體工(gong)程施(shi)工(gong)。然而，持續的雨雪冰凍使得工(gong)區(qu)(qu)水(shui)、電(dian)和(he)(he)(he)物資(zi)供應全部(bu)(bu)(bu)中斷，圍堰(yan)閉氣施(shi)工(gong)也被迫(po)停止。

電站(zhan)建設的(de)(de)環節絲絲相扣，工(gong)期絕不允許隨(sui)意(yi)拖延，否則，汛期到來(lai)，可(ke)能造成難(nan)以估量的(de)(de)損失。面對(dui)生產、生活上的(de)(de)困難(nan)，項目部黨委“一班人”身先(xian)士卒、沉著應戰(zhan)，打響了“大(da)干二月戰(zhan)雪災，閉氣固堤搶工(gong)期”的(de)(de)攻堅戰(zhan)。

通過分析施(shi)工(gong)形勢，項(xiang)目(mu)部(bu)提(ti)出了(le)停電不停工(gong)、備(bei)(bei)戰搶工(gong)期的應對思(si)路。在(zai)交通不暢的情況下，項(xiang)目(mu)部(bu)主任(ren)聶國(guo)旺帶領官(guan)兵冒雪步行(xing)20多公里購買了(le)手(shou)套、儲水罐等(deng)生產(chan)(chan)生活必需品(pin)。在(zai)臨時電源未供電前，項(xiang)目(mu)部(bu)積極(ji)組織官(guan)兵維修機械(xie)設備(bei)(bei)、準(zhun)備(bei)(bei)施(shi)工(gong)材料。工(gong)區臨時電源恢(hui)復供電后，項(xiang)目(mu)部(bu)立即(ji)組織官(guan)兵恢(hui)復生產(chan)(chan)，實行(xing)晝夜兩班倒施(shi)工(gong)，全體人員吃(chi)住在(zai)施(shi)工(gong)一(yi)線。

2008年自2月(yue)上(shang)(shang)旬恢(hui)復生(sheng)產以來(lai)，項目部(bu)共(gong)完(wan)(wan)成了(le)2100噸水(shui)(shui)泥、粗沙(sha)1300立方米(mi)的(de)(de)堵水(shui)(shui)灌(guan)漿閉(bi)氣任(ren)務，搶回因雨(yu)雪耽(dan)誤的(de)(de)工(gong)(gong)(gong)(gong)期(qi)(qi)17天。2008年2月(yue)19日(ri)下(xia)午，項目部(bu)傳(chuan)出喜(xi)訊，上(shang)(shang)下(xia)游(you)圍堰的(de)(de)主(zhu)要漏(lou)水(shui)(shui)點已閉(bi)氣完(wan)(wan)畢，按期(qi)(qi)完(wan)(wan)成了(le)灌(guan)漿施工(gong)(gong)(gong)(gong)任(ren)務。沙(sha)沱(tuo)水(shui)(shui)電站(zhan)今年左岸已實現二(er)期(qi)(qi)大(da)(da)江(jiang)截流，截流后，如(ru)(ru)果遭遇二(er)十年一遇洪(hong)水(shui)(shui)將(jiang)(jiang)淇灘集鎮老街(jie)及彭華下(xia)下(xia)兩(liang)村(cun)全(quan)(quan)部(bu)淹(yan)沒(mei)。因此(ci)，為(wei)了(le)廣(guang)大(da)(da)移(yi)(yi)(yi)民(min)群眾(zhong)生(sheng)命財(cai)產安全(quan)(quan)，確保(bao)(bao)在汛(xun)(xun)期(qi)(qi)來(lai)臨之前，將(jiang)(jiang)淹(yan)沒(mei)線下(xia)的(de)(de)移(yi)(yi)(yi)民(min)群眾(zhong)在2010年5月(yue)底(di)全(quan)(quan)部(bu)搬(ban)出淹(yan)沒(mei)區(qu)外(wai)。為(wei)了(le)加(jia)大(da)(da)度(du)(du)汛(xun)(xun)搬(ban)遷工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)力(li)度(du)(du)，成立了(le)以縣(xian)委副書記冉敏為(wei)指揮長(chang)的(de)(de)度(du)(du)汛(xun)(xun)搬(ban)遷工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)領(ling)(ling)導小(xiao)組，并實行干(gan)部(bu)包(bao)保(bao)(bao)責(ze)任(ren)制(zhi)，將(jiang)(jiang)對(dui)320戶度(du)(du)汛(xun)(xun)移(yi)(yi)(yi)民(min)實行搬(ban)遷。縣(xian)直機(ji)關主(zhu)要負責(ze)人和(he)淇灘鎮干(gan)部(bu)職工(gong)(gong)(gong)(gong)共(gong)同包(bao)保(bao)(bao)，確保(bao)(bao)5月(yue)底(di)前全(quan)(quan)面完(wan)(wan)成度(du)(du)汛(xun)(xun)搬(ban)遷任(ren)務，并由(you)縣(xian)紀委和(he)縣(xian)委、政(zheng)府督(du)(du)查(cha)(cha)室對(dui)責(ze)任(ren)單位和(he)包(bao)保(bao)(bao)干(gan)部(bu)的(de)(de)工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)開(kai)展進行跟蹤(zong)督(du)(du)查(cha)(cha)，并將(jiang)(jiang)督(du)(du)查(cha)(cha)情況向全(quan)(quan)縣(xian)通報，對(dui)辦事較差、工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)滯后且(qie)嚴(yan)(yan)重影響度(du)(du)汛(xun)(xun)搬(ban)遷工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)的(de)(de)單位和(he)個(ge)人將(jiang)(jiang)嚴(yan)(yan)格追究相關責(ze)任(ren)人的(de)(de)責(ze)任(ren)。做好移(yi)(yi)(yi)民(min)度(du)(du)汛(xun)(xun)搬(ban)遷工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)，關系到人民(min)群眾(zhong)生(sheng)命財(cai)產安全(quan)(quan)，沙(sha)沱(tuo)電站(zhan)2011年能否如(ru)(ru)期(qi)(qi)實現第一臺機(ji)組投產發(fa)(fa)電和(he)事關全(quan)(quan)縣(xian)移(yi)(yi)(yi)民(min)工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)大(da)(da)局(ju)。一要加(jia)強(qiang)(qiang)領(ling)(ling)導，密切配合(he)。各級各部(bu)門要切實加(jia)強(qiang)(qiang)對(dui)度(du)(du)汛(xun)(xun)搬(ban)遷工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)的(de)(de)領(ling)(ling)導，落實責(ze)任(ren)，明確工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)任(ren)務。二(er)要加(jia)大(da)(da)宣傳(chuan)氛圍。繼續(xu)廣(guang)泛深(shen)入(ru)開(kai)展移(yi)(yi)(yi)民(min)政(zheng)策(ce)和(he)相關法(fa)(fa)律法(fa)(fa)規宣傳(chuan)，積極引(yin)導移(yi)(yi)(yi)民(min)群眾(zhong)理(li)解、支持和(he)配合(he)度(du)(du)汛(xun)(xun)工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)。三要強(qiang)(qiang)化責(ze)任(ren)，嚴(yan)(yan)肅(su)(su)紀律。深(shen)入(ru)到移(yi)(yi)(yi)民(min)家中(zhong)開(kai)展思(si)想(xiang)發(fa)(fa)動，溝(gou)通思(si)想(xiang)、理(li)順情緒(xu)，盡力(li)幫(bang)助(zhu)移(yi)(yi)(yi)民(min)在搬(ban)遷過程中(zhong)遇到的(de)(de)困難。四要依法(fa)(fa)行政(zheng)，維護穩定。要深(shen)入(ru)開(kai)展矛(mao)盾糾紛排查(cha)(cha)工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)，做到早(zao)發(fa)(fa)現、早(zao)預防、早(zao)處(chu)理(li)，確保(bao)(bao)消滅在萌芽狀態。五要加(jia)強(qiang)(qiang)督(du)(du)促檢查(cha)(cha)。切實加(jia)大(da)(da)對(dui)度(du)(du)汛(xun)(xun)搬(ban)遷工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)的(de)(de)督(du)(du)促檢查(cha)(cha)力(li)度(du)(du)，對(dui)思(si)想(xiang)認識不到位、工(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)不力(li)的(de)(de)要作(zuo)(zuo)(zuo)出嚴(yan)(yan)肅(su)(su)處(chu)理(li)。
