9月21日，中國石(shi)油管道局(ju)西氣東輸(shu)二(er)線西段EPC項目西二(er)線西段共153處三(san)穿工程日前(qian)全部完工，為10月底(di)實(shi)現機械完工、11月底(di)具備(bei)置換投產(chan)條件(jian)贏得了時間。
西(xi)二線(xian)西(xi)段共有(you)153處(chu)(chu)單出圖(tu)穿(chuan)(chuan)越(yue)，其(qi)中隧道工程穿(chuan)(chuan)越(yue)10條、大中型河流穿(chuan)(chuan)越(yue)15處(chu)(chu)、鐵路(lu)穿(chuan)(chuan)越(yue)12處(chu)(chu)、高等(deng)級(ji)公路(lu)穿(chuan)(chuan)越(yue)89處(chu)(chu)，此外還有(you)古長城穿(chuan)(chuan)越(yue)、渠道穿(chuan)(chuan)越(yue)等(deng)。西(xi)二線(xian)西(xi)段三(san)穿(chuan)(chuan)穿(chuan)(chuan)越(yue)點經過(guo)西(xi)部戈壁、沙漠、黃土塬(yuan)和人文環境地點區(qu)域，施工協調難度大、技術(shu)要求高、工期緊迫，給(gei)施工人員帶來巨大壓力。
為(wei)了按期、優質(zhi)、安全完成(cheng)隧道、河流、公路、鐵路等(deng)穿越點(dian)工(gong)程(cheng)，管(guan)道局(ju)西二線西段EPC項目(mu)部(bu)設立協(xie)調組，由(you)項目(mu)部(bu)主管(guan)領導負責，實(shi)行(xing)管(guan)理(li)前置(zhi)制(zhi)度，協(xie)調人員在施(shi)工(gong)現場完成(cheng)報(bao)驗、界面確認、技術(shu)服(fu)務以(yi)及施(shi)工(gong)計劃督導。針對果子溝隧道施(shi)工(gong)塌方(fang)、中(zhong)毒、環(huan)保及洞內安裝(zhuang)有限空間作業等(deng)問題，項目(mu)部(bu)加強日檢制(zhi)度，及時發布QHSE緊(jin)急預警通知(zhi)，監(jian)督承(cheng)包商(shang)整改(gai)不合(he)格項目(mu)，為(wei)促進(jin)工(gong)程(cheng)建設進(jin)度創造有利條件。
在(zai)穿(chuan)越(yue)河流(liu)(liu)中(zhong)(zhong)，項(xiang)(xiang)目(mu)部(bu)和(he)(he)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)單位(wei)根(gen)據當地(di)水(shui)(shui)(shui)文資料，在(zai)河流(liu)(liu)枯(ku)水(shui)(shui)(shui)季節(jie)施(shi)行(xing)大開(kai)挖施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)，既保(bao)(bao)(bao)(bao)證工(gong)(gong)(gong)(gong)(gong)(gong)期不受(shou)影響，也保(bao)(bao)(bao)(bao)護(hu)(hu)河流(liu)(liu)水(shui)(shui)(shui)源(yuan)不受(shou)污染。項(xiang)(xiang)目(mu)部(bu)在(zai)三(san)穿(chuan)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)中(zhong)(zhong)重視(shi)環(huan)保(bao)(bao)(bao)(bao)措(cuo)施(shi)的落實，嚴格執行(xing)國家和(he)(he)地(di)方(fang)(fang)法(fa)律、法(fa)規、條例(li)，堅(jian)持“預防(fang)為(wei)主，防(fang)治結合(he)”方(fang)(fang)針，在(zai)果子溝、大東溝、賽里木(mu)湖、安西極(ji)旱自然(ran)保(bao)(bao)(bao)(bao)護(hu)(hu)區等重點(dian)區域施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)前，制訂并(bing)向(xiang)地(di)方(fang)(fang)環(huan)保(bao)(bao)(bao)(bao)部(bu)門(men)報(bao)審專項(xiang)(xiang)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)方(fang)(fang)案。施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)過程中(zhong)(zhong)，嚴格按設計技術(shu)要(yao)求(qiu)進行(xing)水(shui)(shui)(shui)工(gong)(gong)(gong)(gong)(gong)(gong)保(bao)(bao)(bao)(bao)護(hu)(hu)和(he)(he)地(di)貌(mao)恢復工(gong)(gong)(gong)(gong)(gong)(gong)作，持續完善(shan)水(shui)(shui)(shui)土保(bao)(bao)(bao)(bao)持和(he)(he)環(huan)境保(bao)(bao)(bao)(bao)護(hu)(hu)管理工(gong)(gong)(gong)(gong)(gong)(gong)作。在(zai)幾處古跡遺址穿(chuan)越(yue)中(zhong)(zhong)，項(xiang)(xiang)目(mu)部(bu)設計、外(wai)部(bu)協調(diao)及施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)單位(wei)多次現場(chang)踏勘，制訂頂管穿(chuan)越(yue)方(fang)(fang)式(shi)。該(gai)項(xiang)(xiang)目(mu)部(bu)采用(yong)經(jing)緯儀測出穿(chuan)越(yue)管段中(zhong)(zhong)心(xin)(xin)線(xian)，用(yong)水(shui)(shui)(shui)準儀測量校正液(ye)壓頂管機和(he)(he)穿(chuan)越(yue)套管位(wei)置，使套管中(zhong)(zhong)心(xin)(xin)線(xian)與設計中(zhong)(zhong)心(xin)(xin)線(xian)相吻(wen)合(he)，保(bao)(bao)(bao)(bao)證每一次穿(chuan)越(yue)均一次成功。
