袁(yuan)占亭(ting)在(zai)(zai)儀式上(shang)致辭時說，蘭州(zhou)水(shui)(shui)(shui)(shui)(shui)源(yuan)(yuan)地項目既是(shi)(shi)民生工程，也是(shi)(shi)在(zai)(zai)實(shi)踐(jian)中(zhong)不斷探索的(de)(de)創(chuang)新工程。由中(zhong)鐵工程裝(zhuang)備(bei)集團(tuan)聯合黃河(he)勘測規劃設(she)計有限公司、中(zhong)國水(shui)(shui)(shui)(shui)(shui)利(li)水(shui)(shui)(shui)(shui)(shui)電四局共同設(she)計研發制造的(de)(de)TBM，專門為蘭州(zhou)水(shui)(shui)(shui)(shui)(shui)源(yuan)(yuan)地項目量(liang)身定制，在(zai)(zai)隧洞開(kai)挖(wa)上(shang)能(neng)(neng)夠(gou)根(gen)據地質(zhi)情況靈活(huo)選用不同的(de)(de)掘進(jin)(jin)模式。隨著這一(yi)新設(she)備(bei)的(de)(de)投入(ru)(ru)使用，蘭州(zhou)水(shui)(shui)(shui)(shui)(shui)源(yuan)(yuan)地項目建設(she)一(yi)定能(neng)(neng)夠(gou)進(jin)(jin)入(ru)(ru)施工的(de)(de)快(kuai)車道，一(yi)定能(neng)(neng)夠(gou)加快(kuai)建成造福人民的(de)(de)精品工程，一(yi)定能(neng)(neng)夠(gou)讓安(an)全(quan)、優質(zhi)、干凈的(de)(de)水(shui)(shui)(shui)(shui)(shui)源(yuan)(yuan)早日流進(jin)(jin)蘭州(zhou)的(de)(de)千(qian)家萬戶。

據悉，蘭州市水(shui)(shui)(shui)(shui)(shui)(shui)(shui)源地(di)(di)建(jian)設工(gong)(gong)程(cheng)(cheng)包括取水(shui)(shui)(shui)(shui)(shui)(shui)(shui)口、輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)隧(sui)洞(dong)(dong)主(zhu)洞(dong)(dong)、分水(shui)(shui)(shui)(shui)(shui)(shui)(shui)井、蘆家(jia)坪(ping)輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)支線、彭(peng)家(jia)坪(ping)輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)支線及(ji)其調(diao)流調(diao)壓(ya)站、蘆家(jia)坪(ping)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)廠和彭(peng)家(jia)坪(ping)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)廠以及(ji)兩(liang)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)廠與現(xian)有市政管(guan)網銜接的(de)(de)管(guan)線工(gong)(gong)程(cheng)(cheng)等。該工(gong)(gong)程(cheng)(cheng)輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)隧(sui)洞(dong)(dong)主(zhu)洞(dong)(dong)全(quan)(quan)長31.57km，輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)洞(dong)(dong)涇4.6m。自8月(yue)20日(ri)輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)隧(sui)洞(dong)(dong)工(gong)(gong)程(cheng)(cheng)開(kai)工(gong)(gong)至(zhi)今，短短5個月(yue)時(shi)間里，整(zheng)個工(gong)(gong)程(cheng)(cheng)29個工(gong)(gong)作面已全(quan)(quan)面開(kai)工(gong)(gong)。輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)主(zhu)隧(sui)洞(dong)(dong)是控制水(shui)(shui)(shui)(shui)(shui)(shui)(shui)源地(di)(di)項(xiang)目工(gong)(gong)程(cheng)(cheng)工(gong)(gong)期(qi)的(de)(de)關鍵工(gong)(gong)作，通(tong)過(guo)技術比較，選用兩(liang)臺TBM快速施(shi)工(gong)(gong)主(zhu)隧(sui)洞(dong)(dong)，對于輸(shu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)主(zhu)洞(dong)(dong)上3個不良地(di)(di)質(zhi)地(di)(di)段，采用鉆爆(bao)法(fa)的(de)(de)方(fang)式(shi)提前挖出，TBM和鉆爆(bao)法(fa)聯合(he)施(shi)工(gong)(gong)的(de)(de)方(fang)式(shi)，以此保障工(gong)(gong)程(cheng)(cheng)快速順(shun)利(li)施(shi)工(gong)(gong)。

另悉，此次采用的設(she)備是(shi)國產首臺雙護盾TBM，從制造(zao)到(dao)下線，僅用時6個月(yue)，約(yue)為正常制造(zao)周期的一半。輸水(shui)(shui)主洞采用壓(ya)力(li)洞形式，為國內首條(tiao)TBM施工管片(pian)襯砌(qi)條(tiao)件下的壓(ya)力(li)輸水(shui)(shui)隧(sui)洞，將(jiang)為工程建成后運行管理(li)提供極大的便利。同(tong)時，首條(tiao)壓(ya)力(li)隧(sui)洞襯砌(qi)管片(pian)流(liu)水(shui)(shui)線預(yu)制場建成，將(jiang)為TBM快速掘進提供充(chong)足(zu)的“彈(dan)藥”。

始發儀(yi)式(shi)結束(shu)后，虞(yu)海燕一行看望慰問施工現(xian)場的一線工作人員，送去(qu)了(le)慰問品，并致以(yi)新春(chun)的祝福。
