日前，上海(hai)城建(jian)(jian)隧(sui)道股(gu)(gu)份(fen)承建(jian)(jian)的(de)國內(nei)首個(ge)地(di)面出(chu)入(ru)(ru)式(shi)盾構(gou)法(fa)(fa)(fa)隧(sui)道——南京(jing)地(di)鐵(tie)機場線秣陵站～將軍路站區間右線順(shun)利貫(guan)通(tong)。“地(di)面出(chu)入(ru)(ru)式(shi)盾構(gou)法(fa)(fa)(fa)”簡稱GPST工(gong)(gong)(gong)法(fa)(fa)(fa)，盾構(gou)始發(fa)、接(jie)收均(jun)在地(di)面進(jin)行，無需工(gong)(gong)(gong)作井。該工(gong)(gong)(gong)法(fa)(fa)(fa)的(de)使用(yong)，有效(xiao)減(jian)少了(le)(le)(le)征地(di)、拆遷(qian)和(he)施(shi)工(gong)(gong)(gong)影響范圍，實現(xian)了(le)(le)(le)對土體和(he)能源的(de)高效(xiao)利用(yong)，減(jian)少了(le)(le)(le)建(jian)(jian)設資(zi)金(jin)的(de)投入(ru)(ru)，降低了(le)(le)(le)施(shi)工(gong)(gong)(gong)風險，縮(suo)短了(le)(le)(le)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期，對城市軌交(jiao)、隧(sui)道建(jian)(jian)設具有重(zhong)大意義。南京(jing)地(di)鐵(tie)機場線GPST工(gong)(gong)(gong)法(fa)(fa)(fa)隧(sui)道的(de)成功貫(guan)通(tong)，標志著隧(sui)道股(gu)(gu)份(fen)在地(di)面出(chu)入(ru)(ru)式(shi)盾構(gou)法(fa)(fa)(fa)隧(sui)道施(shi)工(gong)(gong)(gong)領(ling)域(yu)中(zhong)實現(xian)了(le)(le)(le)重(zhong)大突破(po)，隧(sui)道施(shi)工(gong)(gong)(gong)技術(shu)已達到世界先(xian)進(jin)水平，打破(po)了(le)(le)(le)國外對GPST技術(shu)的(de)壟斷局面。
