一、發(fa)揮自(zi)身(shen)技(ji)術優勢，成(cheng)功打入地鐵隧道施工市場

近年(nian)來，中(zhong)煤集團五建公司(si)發揮(hui)礦建立(li)井凍結施工(gong)(gong)技(ji)術優(you)勢，從其他地鐵隧(sui)道施工(gong)(gong)企(qi)業(ye)最薄弱(ruo)而自身最擅長的凍結施工(gong)(gong)入(ru)手，成功進入(ru)城(cheng)市(shi)地鐵隧(sui)道旁通道施工(gong)(gong)，擠進地鐵隧(sui)道施工(gong)(gong)分包市(shi)場，推動了技(ji)術創(chuang)新和轉型發展(zhan)。

在凍結施(shi)(shi)(shi)工(gong)(gong)方面，地(di)鐵(tie)隧道凍結施(shi)(shi)(shi)工(gong)(gong)能力保持行業(ye)領先水(shui)平，搶占了全國地(di)鐵(tie)隧道凍結施(shi)(shi)(shi)工(gong)(gong)市場(chang)份額1/3。獨有的(de)平行作(zuo)業(ye)施(shi)(shi)(shi)工(gong)(gong)、始(shi)發接收(shou)段全封閉水(shui)平凍結加固工(gong)(gong)法被(bei)評為省部(bu)級工(gong)(gong)法，并獲施(shi)(shi)(shi)工(gong)(gong)企業(ye)管理協會科學技術創新成果(guo)二等(deng)獎(jiang)；授權發明專(zhuan)利3項(xiang)、實用新型專(zhuan)利13項(xiang)；已成長為長三(san)角地(di)區(qu)地(di)鐵(tie)旁(pang)通道施(shi)(shi)(shi)工(gong)(gong)的(de)主(zhu)力企業(ye)。

在(zai)盾構(gou)施工方面，熟練掌握了土壓平衡盾構(gou)在(zai)各種復(fu)(fu)雜環境下盾構(gou)推(tui)進(jin)(jin)施工技(ji)術、復(fu)(fu)合盾構(gou)推(tui)進(jin)(jin)施工技(ji)術。其中，無鉸接(jie)盾構(gou)極限小曲率半徑(jing)施工法被評(ping)為(wei)省部級工法。盾構(gou)最(zui)高(gao)月度單(dan)進(jin)(jin)442.5米，雙線同時推(tui)進(jin)(jin)月度最(zui)高(gao)進(jin)(jin)尺813米。

在(zai)隧(sui)道(dao)施(shi)工(gong)方面，在(zai)延安小砭溝公路隧(sui)道(dao)施(shi)工(gong)中，將礦山光面爆破技術(shu)成功應用(yong)于(yu)大斷面隧(sui)道(dao)施(shi)工(gong)，安全(quan)、質(zhi)(zhi)量(liang)、進度均得(de)到(dao)業主(zhu)認可，獲得(de)延安市市級文明工(gong)地(di)、陜(shan)西省省級文明工(gong)地(di)，正在(zai)申報陜(shan)西省工(gong)程質(zhi)(zhi)量(liang)最高獎“長安杯”。

二、開拓創新(xin)，轉型發(fa)展效果顯著

目前，該公司年可(ke)同時(shi)施(shi)工(gong)10條(tiao)地鐵盾構作業線，施(shi)工(gong)能力近10公里；年可(ke)同時(shi)施(shi)工(gong)凍結(jie)工(gong)程（聯絡通(tong)道、洞(dong)門）近百個；年可(ke)施(shi)工(gong)公路大斷面隧道工(gong)程2-3個。
