沖刺四季(ji)度(du)、確保全(quan)年紅，沈(shen)陽地鐵(tie)咬(yao)定目標、堅(jian)定信(xin)心(xin)、全(quan)力(li)攻堅(jian)，拉滿“進度(du)條”，確保在建地鐵(tie)項目高質量推進。
在(zai)沈陽(yang)地鐵(tie)1號(hao)線東延線東陵公園站施工現場，各個(ge)作業(ye)面一片忙碌景象(xiang)，盾構機(ji)在(zai)巖土中(zhong)掘進，車站附屬結構也(ye)在(zai)有序施工中(zhong)。
沈陽地鐵(tie)1號線東延線5標(biao)由中鐵(tie)九(jiu)局承(cheng)建，項(xiang)目包含東陵(ling)公(gong)(gong)園站和水(shui)泉(quan)站兩座車(che)(che)站、區(qu)(qu)間風井及(ji)東陵(ling)公(gong)(gong)園站至水(shui)泉(quan)站區(qu)(qu)間盾(dun)構(gou)(gou)施(shi)(shi)工(gong)。東水(shui)盾(dun)構(gou)(gou)區(qu)(qu)間全長2700米，期間需貫穿(chuan)長白山(shan)余(yu)脈天柱山(shan)，途經東陵(ling)公(gong)(gong)園、荷花池、賽特奧萊商(shang)圈(quan)和多個住宅區(qu)(qu)，為1號線東延線最長盾(dun)構(gou)(gou)區(qu)(qu)間。施(shi)(shi)工(gong)中，為進(jin)一步加(jia)快(kuai)施(shi)(shi)工(gong)進(jin)度(du)，項(xiang)目采用4臺土壓平衡式盾(dun)構(gou)(gou)機，由東陵(ling)公(gong)(gong)園和水(shui)泉(quan)站兩站雙向對發，掘進(jin)至區(qu)(qu)間風井處匯(hui)合并進(jin)行(xing)接(jie)收。截止8月底，兩座車(che)(che)站及(ji)區(qu)(qu)間風井明挖主體結(jie)構(gou)(gou)施(shi)(shi)工(gong)已順利完成(cheng)封頂。目前(qian)，項(xiang)目正(zheng)全力攻堅盾(dun)構(gou)(gou)區(qu)(qu)間施(shi)(shi)工(gong)，有(you)序(xu)推(tui)進(jin)車(che)(che)站附屬(shu)結(jie)構(gou)(gou)施(shi)(shi)工(gong)。
作為(wei)(wei)(wei)項(xiang)目(mu)施(shi)工(gong)(gong)重點(dian)，此次盾(dun)構區間穿(chuan)越(yue)地(di)(di)(di)層(ceng)上部主要(yao)為(wei)(wei)(wei)圓礫和(he)(he)全風(feng)化(hua)花(hua)(hua)崗巖，下部主要(yao)為(wei)(wei)(wei)強(qiang)風(feng)化(hua)和(he)(he)中風(feng)化(hua)花(hua)(hua)崗巖，屬于(yu)典型的上軟(ruan)下硬地(di)(di)(di)層(ceng)，施(shi)工(gong)(gong)過(guo)程(cheng)中容(rong)易出(chu)現(xian)地(di)(di)(di)面塌(ta)陷、盾(dun)構機(ji)姿(zi)態不易控制、掘(jue)(jue)進(jin)速度緩慢等(deng)情況，掘(jue)(jue)進(jin)過(guo)程(cheng)中還需解決(jue)刀具偏磨(mo)、噴(pen)涌(yong)、渣(zha)(zha)土改良、小半(ban)徑掘(jue)(jue)進(jin)等(deng)技(ji)術難(nan)題(ti)，對施(shi)工(gong)(gong)要(yao)求較高，施(shi)工(gong)(gong)難(nan)度和(he)(he)挑戰較大。為(wei)(wei)(wei)此，地(di)(di)(di)鐵集團和(he)(he)中鐵九局項(xiang)目(mu)部多(duo)次進(jin)行專題(ti)技(ji)術研究交(jiao)流，有針對性(xing)的選(xuan)擇施(shi)工(gong)(gong)工(gong)(gong)法，科(ke)學組織施(shi)工(gong)(gong)，加強(qiang)現(xian)場技(ji)術指導，嚴抓施(shi)工(gong)(gong)安(an)全和(he)(he)質(zhi)量(liang)，全力攻堅克難(nan)。目(mu)前，針對各(ge)項(xiang)難(nan)點(dian)，項(xiang)目(mu)已采取(qu)氣(qi)壓(ya)輔(fu)助、渣(zha)(zha)土改良、道具優化(hua)、提前預加固、地(di)(di)(di)質(zhi)補勘、管線超前探測等(deng)多(duo)項(xiang)措(cuo)施(shi)確(que)保項(xiang)目(mu)能夠安(an)全有序建設，奮力實現(xian)區間雙線貫通(tong)目(mu)標。
下一步，地(di)鐵集團將與(yu)中鐵九局項目部一道，全(quan)力(li)以赴(fu)、攻堅克難(nan)，苦干(gan)實干(gan)、大干(gan)快干(gan)，深入實施全(quan)面(mian)(mian)振興新(xin)突破三年行動(dong)及(ji)“振興新(xin)突破、我要當先鋒”專項行動(dong)，始終保持拼勁、闖勁、韌(ren)勁，為沈(shen)(shen)城市民建(jian)設(she)精品地(di)鐵工程，奮力(li)譜寫沈(shen)(shen)陽全(quan)面(mian)(mian)振興新(xin)篇章。
