6月2日上(shang)午(wu)，中國電建(jian)(jian)集團以BT模式投資建(jian)(jian)設的(de)成都地(di)鐵(tie)4號線(xian)二期工程正(zheng)式通(tong)(tong)車載客(ke)試運營。這(zhe)是繼深圳地(di)鐵(tie)7號線(xian)后，中國電建(jian)(jian)承建(jian)(jian)開通(tong)(tong)運營的(de)又一(yi)條地(di)鐵(tie)線(xian)工程。

成都地鐵4號線二期工(gong)程采用“投融資+設(she)計施工(gong)總承包+回報(bao)”的(de)建設(she)模(mo)式，實際合同額約(yue)(yue)為(wei)69億元(yuan)。項目全長約(yue)(yue)22公(gong)里，分為(wei)東、西延(yan)線。共設(she)14座車(che)(che)站。單程運行時(shi)間約(yue)(yue)為(wei)69分鐘，旅行速度(du)約(yue)(yue)為(wei)每小時(shi)36公(gong)里，高峰上線列車(che)(che)43列，最小行車(che)(che)間隔3分10秒(miao)。

該項(xiang)(xiang)目是(shi)中(zhong)國(guo)電建(jian)(jian)集成設計(ji)、施工(gong)(gong)、裝備制造等優勢資(zi)源，發揮全(quan)產業鏈優勢實施的地鐵項(xiang)(xiang)目之一。工(gong)(gong)程(cheng)自(zi)開(kai)工(gong)(gong)以來，中(zhong)國(guo)電建(jian)(jian)確立了“一個理(li)念、兩部建(jian)(jian)設、三化(hua)建(jian)(jian)設、四維推動(dong)”的項(xiang)(xiang)目建(jian)(jian)設舉措，堅持“全(quan)力(li)以赴(fu)攻難關，一絲(si)不茍做細節(jie)，精工(gong)(gong)良建(jian)(jian)鑄完美，把握今天創未來”的建(jian)(jian)設理(li)念，抓好(hao)指揮部和標(biao)段項(xiang)(xiang)目經理(li)部“兩部”建(jian)(jian)設，推進專(zhuan)業化(hua)、規(gui)范化(hua)和標(biao)準(zhun)化(hua)“三化(hua)”管理(li)，通(tong)過(guo)施工(gong)(gong)進度、現場管理(li)、綜(zong)合評比、市(shi)場拓展四個維度，確保了精品質量和工(gong)(gong)程(cheng)進度，優質高效(xiao)地實現了開(kai)通(tong)試(shi)運營的總體目標(biao)。

該工(gong)(gong)程具(ju)有工(gong)(gong)期緊、接(jie)口(kou)多(duo)(duo)、地(di)(di)質(zhi)復(fu)雜(za)、施(shi)工(gong)(gong)難(nan)度大等特(te)點(dian)(dian)。特(te)別是(shi)西延線地(di)(di)質(zhi)具(ju)有大粒徑、高(gao)強(qiang)度、高(gao)富水(shui)、強(qiang)透水(shui)以(yi)及無膠(jiao)結松(song)散(san)漂卵(luan)(luan)石(shi)地(di)(di)層的(de)(de)難(nan)點(dian)(dian)，在(zai)全國(guo)乃至國(guo)際(ji)上(shang)都(dou)(dou)是(shi)極(ji)為罕見(jian)復(fu)雜(za)地(di)(di)質(zhi)，稍有不(bu)慎就極(ji)易造成(cheng)地(di)(di)面坍(tan)塌、陷(xian)落。中國(guo)電(dian)建利用“推(tui)力(li)脫困法(fa)(fa)”、“渣土改(gai)良法(fa)(fa)”等先進工(gong)(gong)藝，有效解決了在(zai)松(song)散(san)漂卵(luan)(luan)石(shi)富水(shui)地(di)(di)質(zhi)條(tiao)件(jian)下(xia)(xia)盾構(gou)機快速脫困，連續掘進和漂卵(luan)(luan)石(shi)頻繁卡刀盤的(de)(de)難(nan)題，攻克(ke)了汛期下(xia)(xia)穿(chuan)約50多(duo)(duo)米(mi)寬的(de)(de)江安(an)河等重大風(feng)險(xian)源(yuan)，創下(xia)(xia)了盾構(gou)機在(zai)松(song)散(san)砂礫石(shi)富水(shui)地(di)(di)質(zhi)條(tiao)件(jian)下(xia)(xia)成(cheng)功下(xia)(xia)穿(chuan)河道、盾構(gou)一(yi)(yi)(yi)日(ri)掘進25環(huan)兩項第(di)一(yi)(yi)(yi)。在(zai)成(cheng)都(dou)(dou)地(di)(di)鐵建設(she)史上(shang)第(di)一(yi)(yi)(yi)次(ci)(ci)實現(xian)了全線整(zheng)體(ti)移交；第(di)一(yi)(yi)(yi)次(ci)(ci)首站綜合聯調通(tong)過(guo)(guo)率超(chao)過(guo)(guo)99%，首站消防檢測(ce)一(yi)(yi)(yi)次(ci)(ci)性通(tong)過(guo)(guo)；第(di)一(yi)(yi)(yi)次(ci)(ci)正線軌行區(qu)與停車場同步整(zheng)體(ti)移交，被驗(yan)收專家(jia)認為推(tui)動軌道工(gong)(gong)程質(zhi)量邁上(shang)新臺階。

在(zai)工(gong)程施工(gong)中(zhong)，中(zhong)國(guo)電建采用了最新(xin)的(de)(de)“BIM技術應(ying)用管理系統(tong)(tong)”，通過收(shou)集施工(gong)圖紙、現場測量數(shu)(shu)據、設備選型尺(chi)寸(cun)、材料選型尺(chi)寸(cun)等各(ge)類數(shu)(shu)據，在(zai)統(tong)(tong)一(yi)(yi)(yi)的(de)(de)3D平臺進行繪制(zhi)，用于分析、研(yan)判(pan)各(ge)管線、設備的(de)(de)相互位置(zhi)關(guan)系，具有(you)信(xin)(xin)息完備性、信(xin)(xin)息關(guan)聯性、信(xin)(xin)息一(yi)(yi)(yi)致性、可(ke)視化、協調性、模擬性、優化性和可(ke)出(chu)圖性八(ba)大(da)特點，極(ji)大(da)提高了地(di)鐵投運后運營(ying)維護管理的(de)(de)效率。該工(gong)程車站(zhan)裝修在(zai)標準化、統(tong)(tong)一(yi)(yi)(yi)化基礎上，根據車站(zhan)所處(chu)地(di)域環境派(pai)生出(chu)文化個性，在(zai)“整體(ti)統(tong)(tong)一(yi)(yi)(yi)、各(ge)有(you)表達(da)、藝(yi)術點睛、一(yi)(yi)(yi)站(zhan)一(yi)(yi)(yi)景”藝(yi)術理念(nian)指(zhi)導下，實現個性與共性的(de)(de)統(tong)(tong)一(yi)(yi)(yi)。

地(di)鐵4號(hao)線(xian)是成(cheng)(cheng)都(dou)軌道(dao)交通線(xian)網中的(de)東(dong)西(xi)向骨(gu)干線(xian)路，二(er)期(qi)工(gong)(gong)程在一(yi)期(qi)工(gong)(gong)程的(de)基礎上延(yan)城(cheng)市(shi)(shi)東(dong)西(xi)軸(zhou)線(xian)，完善了4號(hao)線(xian)的(de)東(dong)西(xi)向骨(gu)干功(gong)能。此次二(er)期(qi)工(gong)(gong)程的(de)如期(qi)開通，對于加(jia)快成(cheng)(cheng)都(dou)城(cheng)市(shi)(shi)軌道(dao)交通加(jia)速(su)(su)成(cheng)(cheng)網建(jian)設，實(shi)現“雙核共(gong)興、一(yi)城(cheng)多市(shi)(shi)”網絡城(cheng)市(shi)(shi)群大(da)都(dou)市(shi)(shi)發(fa)展格局，方便沿線(xian)市(shi)(shi)民出行具(ju)有重要的(de)現實(shi)意(yi)義。同時推動中國(guo)電建(jian)以地(di)鐵4號(hao)線(xian)二(er)期(qi)工(gong)(gong)程的(de)優異(yi)現場換得了優質市(shi)(shi)場，實(shi)現了從(cong)BT模式向PPP模式的(de)成(cheng)(cheng)功(gong)跨越，成(cheng)(cheng)功(gong)簽約成(cheng)(cheng)都(dou)最(zui)長(chang)的(de)軌道(dao)交通項(xiang)(xiang)目——18號(hao)線(xian)工(gong)(gong)程PPP項(xiang)(xiang)目，參(can)與到成(cheng)(cheng)都(dou)市(shi)(shi)加(jia)速(su)(su)成(cheng)(cheng)網的(de)地(di)鐵建(jian)設中。
