日前，上(shang)海城(cheng)建(jian)(jian)(jian)隧(sui)道股(gu)份承建(jian)(jian)(jian)的(de)(de)(de)國(guo)內(nei)首個地(di)(di)面出(chu)入(ru)式(shi)盾構(gou)(gou)(gou)法(fa)(fa)隧(sui)道——南京(jing)地(di)(di)鐵(tie)(tie)機場線秣(mo)陵站～將軍路站區間右線順利貫通。“地(di)(di)面出(chu)入(ru)式(shi)盾構(gou)(gou)(gou)法(fa)(fa)”簡稱GPST工(gong)(gong)(gong)法(fa)(fa)，盾構(gou)(gou)(gou)始發、接收均在(zai)地(di)(di)面進(jin)行，無需工(gong)(gong)(gong)作井。該(gai)工(gong)(gong)(gong)法(fa)(fa)的(de)(de)(de)使用(yong)，有效減(jian)少了征地(di)(di)、拆遷和施(shi)工(gong)(gong)(gong)影響(xiang)范圍，實現(xian)了對土(tu)體和能(neng)源(yuan)的(de)(de)(de)高效利用(yong)，減(jian)少了建(jian)(jian)(jian)設資金的(de)(de)(de)投入(ru)，降低(di)了施(shi)工(gong)(gong)(gong)風險(xian)，縮短(duan)了施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期，對城(cheng)市(shi)軌交、隧(sui)道建(jian)(jian)(jian)設具有重大意義。南京(jing)地(di)(di)鐵(tie)(tie)機場線GPST工(gong)(gong)(gong)法(fa)(fa)隧(sui)道的(de)(de)(de)成功貫通，標志著隧(sui)道股(gu)份在(zai)地(di)(di)面出(chu)入(ru)式(shi)盾構(gou)(gou)(gou)法(fa)(fa)隧(sui)道施(shi)工(gong)(gong)(gong)領(ling)域中實現(xian)了重大突破(po)，隧(sui)道施(shi)工(gong)(gong)(gong)技術已達到世界先進(jin)水平，打破(po)了國(guo)外對GPST技術的(de)(de)(de)壟斷(duan)局面。
