　　穿黃(huang)(huang)工(gong)(gong)程是(shi)南水(shui)北調(diao)中線干線的關鍵工(gong)(gong)程，隧(sui)洞內(nei)徑(jing)7米，外徑(jing)8.7米，深埋于(yu)黃(huang)(huang)河(he)河(he)床下23至35米處，采(cai)用盾構(gou)(gou)技術開挖掘進。這(zhe)是(shi)我國首(shou)(shou)次(ci)采(cai)用大直徑(jing)盾構(gou)(gou)機穿越黃(huang)(huang)河(he)，也(ye)是(shi)我國首(shou)(shou)次(ci)采(cai)用盾構(gou)(gou)技術在軟基進行(xing)長距離輸水(shui)隧(sui)道工(gong)(gong)程，具有極大的技術挑戰性。葛洲壩集團(tuan)五公司承擔了穿黃(huang)(huang)隧(sui)洞II-A標(biao)的施工(gong)(gong)。該標(biao)段的穿黃(huang)(huang)隧(sui)洞全(quan)長4250米，使用泥水(shui)平衡式盾構(gou)(gou)機自北向南推進。工(gong)(gong)程于(yu)2005年(nian)9月開工(gong)(gong)，計劃于(yu)2010年(nian)3月完工(gong)(gong)，總工(gong)(gong)期(qi)54.7個月。

　　工(gong)(gong)(gong)(gong)程開工(gong)(gong)(gong)(gong)以來，葛洲壩穿黃(huang)項目(mu)部(bu)按照“營造(zao)和諧文(wen)(wen)明(ming)建設環境，創建世(shi)紀(ji)一流精(jing)品工(gong)(gong)(gong)(gong)程”的(de)思路，狠抓安全(quan)、文(wen)(wen)明(ming)施(shi)工(gong)(gong)(gong)(gong)，嚴(yan)格施(shi)工(gong)(gong)(gong)(gong)質量控(kong)制，使工(gong)(gong)(gong)(gong)程建設順利推(tui)進。目(mu)前，項目(mu)部(bu)已完成(cheng)質量評(ping)定(ding)的(de)單元工(gong)(gong)(gong)(gong)程達134個，評(ping)定(ding)優(you)良率(lv)為96.2%；項目(mu)部(bu)全(quan)年(nian)無安全(quan)責任事故發生；文(wen)(wen)明(ming)施(shi)工(gong)(gong)(gong)(gong)也受(shou)到(dao)上級主管部(bu)門的(de)好評(ping)，先(xian)后被國務(wu)院南水北(bei)調(diao)工(gong)(gong)(gong)(gong)程建設委(wei)員會辦公室授予(yu)“文(wen)(wen)明(ming)施(shi)工(gong)(gong)(gong)(gong)單位(wei)”、“文(wen)(wen)明(ming)工(gong)(gong)(gong)(gong)地”稱(cheng)號(hao)。
