近日，中國冶金科工集團華冶資源開發有限責任公司在武鋼大冶鐵礦東副井工程治理井筒涌水中，實施靜水止漿墊施工工藝獲得成功。
去年12月，武鋼礦業公司大冶鐵礦東副井工程當豎井掘至-41米時，因涌水量過大被迫停工。今年3月，華冶資源在業主招標治水中中標。
幾個月來，在工(gong)(gong)(gong)程施工(gong)(gong)(gong)難度(du)大、沒有(you)施工(gong)(gong)(gong)經驗可(ke)借(jie)鑒的情況下，針(zhen)對如何使(shi)井(jing)(jing)筒底部(bu)砼墊層達到所要求強度(du)、控制(zhi)水(shui)泥漿(jiang)液比例及(ji)(ji)輸(shu)送(song)管路(lu)如何下送(song)到水(shui)下工(gong)(gong)(gong)作(zuo)面等問題，工(gong)(gong)(gong)程技術人員(yuan)開(kai)展(zhan)治(zhi)水(shui)攻關。經過多(duo)種方案比較和(he)多(duo)次(ci)實驗后，對東副井(jing)(jing)實施了靜(jing)水(shui)止漿(jiang)墊施工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)，獲得(de)成(cheng)功。東副井(jing)(jing)工(gong)(gong)(gong)程已(yi)于8月份復工(gong)(gong)(gong)。目(mu)(mu)前(qian)，井(jing)(jing)筒涌水(shui)量已(yi)經控制(zhi)在3立方米(mi)/時(shi)，項目(mu)(mu)部(bu)將繼續對井(jing)(jing)筒明(ming)顯出水(shui)點進行封堵(du)及(ji)(ji)壁后注漿(jiang)工(gong)(gong)(gong)作(zuo)。
