排壩基故障

沙坨電站(zhan)大(da)壩(ba)(ba)10#壩(ba)(ba)段在開(kai)挖過(guo)程中出現多個巖溶管(guan)道，涌水(shui)量(liang)很大(da)，經原施工單位(wei)處理后(hou)，未能將漏(lou)水(shui)成功封堵(du)，采用在壩(ba)(ba)體內埋(mai)設集水(shui)鋼(gang)盒加排(pai)(pai)水(shui)鋼(gang)管(guan)的(de)方式將涌水(shui)引至基(ji)坑(keng)。涌水(shui)除大(da)部分從引水(shui)鋼(gang)管(guan)排(pai)(pai)出外，另有一部分經混(hun)凝土與基(ji)巖接觸面涌出。緊靠縱向圍堰的(de)10#壩(ba)(ba)段必須在2008年主(zhu)汛(xun)期到來前澆筑(zhu)到指定高程，10#壩(ba)(ba)段內外水(shui)位(wei)高差達(da)18米，滲漏(lou)途(tu)徑短且集中，涌水(shui)量(liang)達(da)10000m3/h，業(ye)主(zhu)委托水(shui)電八局(ju)基(ji)礎分局(ju)對涌水(shui)進行封堵(du)灌漿。

在堵(du)漏的(de)各項工(gong)作中(zhong)技(ji)術方(fang)案的(de)確定(ding)無疑(yi)是重(zhong)中(zhong)之重(zhong)。水(shui)頭(tou)高、滲徑短、工(gong)作面(mian)狹窄、溶蝕裂(lie)隙(xi)錯(cuo)綜復(fu)雜、灌注漿液大量流失，造成堵(du)漏目的(de)難(nan)以(yi)實現，這(zhe)是克服(fu)工(gong)程(cheng)(cheng)難(nan)題的(de)關鍵所在。接到工(gong)程(cheng)(cheng)信(xin)息后，公司經營(ying)人員(yuan)全(quan)力配合，及時做好咨詢(xun)服(fu)務(wu)，為最終施(shi)(shi)工(gong)方(fang)案的(de)確定(ding)提供了有力的(de)支撐。經業主、設計(ji)、監(jian)理、施(shi)(shi)工(gong)單位現場(chang)多(duo)(duo)次勘(kan)察、驗證，在對多(duo)(duo)個方(fang)案的(de)綜合比(bi)較、施(shi)(shi)工(gong)參數反復(fu)調整后最終確定(ding)以(yi)查找(zhao)涌(yong)(yong)水(shui)通道和封(feng)堵(du)涌(yong)(yong)水(shui)相結(jie)合、封(feng)堵(du)涌(yong)(yong)水(shui)采(cai)用(yong)模袋(dai)灌漿和HK-9105油溶性聚氨(an)酯化(hua)學灌漿相結(jie)合的(de)施(shi)(shi)工(gong)技(ji)術方(fang)案。

通過分析施(shi)工(gong)形(xing)勢，項目(mu)部提(ti)出(chu)了(le)停電不停工(gong)、備(bei)戰搶工(gong)期的(de)應對思路。在(zai)交(jiao)通不暢的(de)情況下(xia)，項目(mu)部主任聶(nie)國旺帶領官兵冒(mao)雪步行20多公里購(gou)買了(le)手套、儲水罐等生產生活必需品。在(zai)臨時電源(yuan)未供電前，項目(mu)部積極(ji)組織官兵維修機械設備(bei)、準備(bei)施(shi)工(gong)材料。工(gong)區臨時電源(yuan)恢復供電后，項目(mu)部立即組織官兵恢復生產，實行晝(zhou)夜兩班倒施(shi)工(gong)，全(quan)體人(ren)員吃住在(zai)施(shi)工(gong)一線。
