排壩基故障

沙坨電站大(da)(da)壩(ba)(ba)10#壩(ba)(ba)段在開挖過程(cheng)中出現多個巖(yan)溶管道(dao)，涌(yong)水(shui)(shui)量很(hen)大(da)(da)，經原施工(gong)單位處理后，未能將(jiang)漏水(shui)(shui)成(cheng)功封堵，采用在壩(ba)(ba)體內埋設集水(shui)(shui)鋼(gang)盒加排水(shui)(shui)鋼(gang)管的方式將(jiang)涌(yong)水(shui)(shui)引至基坑。涌(yong)水(shui)(shui)除大(da)(da)部分(fen)從引水(shui)(shui)鋼(gang)管排出外(wai)，另有一部分(fen)經混(hun)凝(ning)土(tu)與基巖(yan)接觸面涌(yong)出。緊(jin)靠(kao)縱向(xiang)圍堰的10#壩(ba)(ba)段必須在2008年主汛(xun)期到來前澆(jiao)筑到指定高程(cheng)，10#壩(ba)(ba)段內外(wai)水(shui)(shui)位高差(cha)達(da)18米，滲漏途(tu)徑(jing)短且集中，涌(yong)水(shui)(shui)量達(da)10000m3/h，業主委托水(shui)(shui)電八(ba)局(ju)基礎分(fen)局(ju)對涌(yong)水(shui)(shui)進行封堵灌漿。

在堵(du)漏(lou)的(de)各項工作中(zhong)技(ji)術(shu)方(fang)(fang)(fang)案(an)的(de)確定無疑(yi)是重中(zhong)之重。水(shui)頭高、滲徑(jing)短、工作面狹窄、溶蝕裂(lie)隙錯(cuo)綜復雜、灌注漿(jiang)液(ye)大量流失(shi)，造成堵(du)漏(lou)目的(de)難以實(shi)現，這是克(ke)服工程難題的(de)關鍵所在。接(jie)到工程信息后，公(gong)司經營人(ren)員(yuan)全力(li)配合(he)(he)，及時做好咨(zi)詢服務，為最終(zhong)施(shi)(shi)工方(fang)(fang)(fang)案(an)的(de)確定提供(gong)了有力(li)的(de)支(zhi)撐。經業主、設計、監理、施(shi)(shi)工單位現場多(duo)次勘察、驗證，在對多(duo)個(ge)方(fang)(fang)(fang)案(an)的(de)綜合(he)(he)比較、施(shi)(shi)工參數反復調整后最終(zhong)確定以查找涌(yong)水(shui)通道和(he)封堵(du)涌(yong)水(shui)相結合(he)(he)、封堵(du)涌(yong)水(shui)采用模袋灌漿(jiang)和(he)HK-9105油(you)溶性聚氨酯化學灌漿(jiang)相結合(he)(he)的(de)施(shi)(shi)工技(ji)術(shu)方(fang)(fang)(fang)案(an)。

2008年7月初在采用以上方案對10#壩(ba)(ba)段(duan)既有涌(yong)水(shui)(shui)進(jin)行了(le)封堵后(hou)，12#壩(ba)(ba)段(duan)基(ji)(ji)坑又(you)出(chu)現了(le)新的(de)(de)(de)涌(yong)水(shui)(shui)點，施工局迅速調整施工工藝及方案，采用對10#壩(ba)(ba)段(duan)上游(you)(you)廊(lang)道(dao)和靠(kao)近(jin)11#壩(ba)(ba)段(duan)基(ji)(ji)礎面澆筑的(de)(de)(de)2m寬混凝土條(tiao)帶，進(jin)行群孔灌注砂漿(jiang)和HK-9105油溶性(xing)聚氨酯材料，起到了(le)較好的(de)(de)(de)堵漏(lou)效果。12#壩(ba)(ba)段(duan)基(ji)(ji)坑內大涌(yong)水(shui)(shui)封閉后(hou)，未出(chu)現新的(de)(de)(de)涌(yong)水(shui)(shui)點，8月初，下游(you)(you)側排水(shui)(shui)鋼管(guan)被漿(jiang)液自行封閉。8月中旬，11#壩(ba)(ba)段(duan)條(tiao)帶與消(xiao)力(li)(li)池附近(jin)又(you)出(chu)現了(le)大的(de)(de)(de)涌(yong)水(shui)(shui)點。由(you)于11#壩(ba)(ba)段(duan)與消(xiao)力(li)(li)池之間條(tiao)帶段(duan)主(zhu)要為浮(fu)渣層，項目部通過在10#壩(ba)(ba)段(duan)邊墻體以及下游(you)(you)廊(lang)道(dao)鉆(zhan)斜孔，仍然采用同樣的(de)(de)(de)方法(fa)進(jin)行堵漏(lou)補強施工，2008年8月29日下午，11#壩(ba)(ba)段(duan)條(tiao)帶與消(xiao)力(li)(li)池附近(jin)大涌(yong)水(shui)(shui)點封堵結束(shu)。經過半個多月的(de)(de)(de)觀(guan)察，10#、11#、12#壩(ba)(ba)段(duan)均未再次(ci)出(chu)現涌(yong)水(shui)(shui)點，宣告此(ci)次(ci)壩(ba)(ba)基(ji)(ji)堵漏(lou)灌漿(jiang)施工任務圓滿結束(shu)。
