近年來，煤炭(tan)產能嚴(yan)重(zhong)過剩，煤炭(tan)基建(jian)市(shi)場(chang)大幅萎縮(suo)。特別是隨著國家供給側結(jie)構性改(gai)革和煤炭(tan)去產能的(de)深入(ru)推進(jin)，煤炭(tan)基建(jian)市(shi)場(chang)進(jin)一步萎縮(suo)。面(mian)對(dui)嚴(yan)峻形勢，中(zhong)煤集團五建(jian)公(gong)司(si)發(fa)揮企業(ye)施(shi)工(gong)(gong)(gong)(gong)技術(shu)優勢，著力把礦建(jian)施(shi)工(gong)(gong)(gong)(gong)技術(shu)引入(ru)地(di)鐵(tie)隧道(dao)施(shi)工(gong)(gong)(gong)(gong)領域，加快(kuai)向地(di)鐵(tie)隧道(dao)施(shi)工(gong)(gong)(gong)(gong)領域轉型，廣泛開展市(shi)政公(gong)用工(gong)(gong)(gong)(gong)程(cheng)、隧道(dao)工(gong)(gong)(gong)(gong)程(cheng)施(shi)工(gong)(gong)(gong)(gong)業(ye)務(wu)，在盾(dun)構施(shi)工(gong)(gong)(gong)(gong)、凍結(jie)施(shi)工(gong)(gong)(gong)(gong)和隧道(dao)施(shi)工(gong)(gong)(gong)(gong)方(fang)(fang)面(mian)積累(lei)了豐(feng)富的(de)經驗(yan)，在市(shi)場(chang)開發(fa)、科技創(chuang)新和管理(li)創(chuang)新方(fang)(fang)面(mian)成(cheng)果豐(feng)碩(shuo)。截至目前，該(gai)公(gong)司(si)通(tong)過專(zhuan)業(ye)分包(bao)的(de)方(fang)(fang)式(shi)，先后在上海、南京、寧(ning)波、天津、合肥累(lei)計完(wan)成(cheng)地(di)鐵(tie)隧道(dao)盾(dun)構推進(jin)46公(gong)里(li)，現有昆明、武漢、天津、合肥等盾(dun)構項目；通(tong)過發(fa)展BT模式(shi)，總(zong)承包(bao)了延安市(shi)小(xiao)砭溝長1.977公(gong)里(li)公(gong)路及隧道(dao)工(gong)(gong)(gong)(gong)程(cheng)；通(tong)過將礦建(jian)凍結(jie)施(shi)工(gong)(gong)(gong)(gong)技術(shu)引入(ru)城(cheng)市(shi)地(di)鐵(tie)施(shi)工(gong)(gong)(gong)(gong)領域，開展專(zhuan)業(ye)承包(bao)方(fang)(fang)式(shi)，在6個(ge)城(cheng)市(shi)完(wan)成(cheng)25個(ge)凍結(jie)項目施(shi)工(gong)(gong)(gong)(gong)。

一、發揮自身技術優(you)勢(shi)，成功打(da)入地鐵隧道施工市場(chang)

近(jin)年來，中煤集團五建(jian)公(gong)司發(fa)揮礦建(jian)立井凍結施(shi)(shi)工技(ji)術優勢，從(cong)其他地(di)(di)鐵(tie)隧(sui)道施(shi)(shi)工企業(ye)最(zui)薄弱(ruo)而(er)自身(shen)最(zui)擅長(chang)的(de)凍結施(shi)(shi)工入(ru)手(shou)，成(cheng)功進入(ru)城市(shi)地(di)(di)鐵(tie)隧(sui)道旁通道施(shi)(shi)工，擠(ji)進地(di)(di)鐵(tie)隧(sui)道施(shi)(shi)工分包(bao)市(shi)場(chang)，推動了技(ji)術創新和(he)轉型發(fa)展。

在(zai)凍結施(shi)工方面，地(di)(di)鐵(tie)隧(sui)(sui)道(dao)凍結施(shi)工能力保(bao)持行(xing)業領先水平(ping)，搶占(zhan)了(le)全國地(di)(di)鐵(tie)隧(sui)(sui)道(dao)凍結施(shi)工市場份額1/3。獨(du)有的平(ping)行(xing)作(zuo)業施(shi)工、始發接收段全封閉水平(ping)凍結加(jia)固工法被評(ping)為省部級工法，并獲施(shi)工企(qi)業管(guan)理協會科學(xue)技術創(chuang)新成果(guo)二等獎；授權(quan)發明專利(li)3項、實用新型專利(li)13項；已成長為長三角地(di)(di)區地(di)(di)鐵(tie)旁(pang)通道(dao)施(shi)工的主力企(qi)業。

在盾(dun)構(gou)施工方(fang)面，熟練掌握了(le)土壓平衡盾(dun)構(gou)在各種復(fu)雜環(huan)境下盾(dun)構(gou)推進(jin)(jin)施工技(ji)術、復(fu)合盾(dun)構(gou)推進(jin)(jin)施工技(ji)術。其中(zhong)，無鉸接盾(dun)構(gou)極限小曲率半徑(jing)施工法(fa)被評為省部級(ji)工法(fa)。盾(dun)構(gou)最(zui)高月(yue)度(du)(du)單(dan)進(jin)(jin)442.5米(mi)(mi)，雙線(xian)同時推進(jin)(jin)月(yue)度(du)(du)最(zui)高進(jin)(jin)尺813米(mi)(mi)。

在(zai)隧(sui)道施工(gong)(gong)方面，在(zai)延安小砭(bian)溝(gou)公路(lu)隧(sui)道施工(gong)(gong)中(zhong)，將礦山光面爆破(po)技術成功應用于大斷面隧(sui)道施工(gong)(gong)，安全(quan)、質(zhi)量、進度均(jun)得到(dao)業主認可，獲得延安市市級文(wen)明工(gong)(gong)地(di)、陜(shan)(shan)西(xi)省省級文(wen)明工(gong)(gong)地(di)，正在(zai)申報(bao)陜(shan)(shan)西(xi)省工(gong)(gong)程質(zhi)量最(zui)高獎(jiang)“長(chang)安杯(bei)”。

二、開拓創新，轉型(xing)發(fa)展效果顯著(zhu)

目前，該公(gong)司年(nian)(nian)可(ke)(ke)同(tong)時(shi)施工10條地鐵(tie)盾構作業(ye)線，施工能(neng)力近(jin)10公(gong)里；年(nian)(nian)可(ke)(ke)同(tong)時(shi)施工凍(dong)結工程（聯絡通道、洞門）近(jin)百個；年(nian)(nian)可(ke)(ke)施工公(gong)路大(da)斷(duan)面隧道工程2-3個。

一是市(shi)場(chang)開(kai)發成效明顯。2016年，該公(gong)司加(jia)大市(shi)場(chang)開(kai)發力(li)度，抓住中鐵(tie)隧道開(kai)拓中立井(jing)建(jian)設(she)的弱項(xiang)，以現(xian)有玉磨隧道豎井(jing)合作為契機，打(da)造精品工(gong)程(cheng)，不斷擴大合作市(shi)場(chang)。大力(li)拓展城(cheng)市(shi)管(guan)(guan)廊(lang)、海綿城(cheng)市(shi)建(jian)設(she)、老(lao)城(cheng)地(di)下管(guan)(guan)網改造等新興市(shi)政工(gong)程(cheng)。通(tong)過不懈努力(li)，該公(gong)司全年承攬(lan)工(gong)程(cheng)22項(xiang)。其中，地(di)鐵(tie)隧道旁通(tong)道37個、洞(dong)門(men)加(jia)固凍結工(gong)程(cheng)9個；盾構(gou)推進項(xiang)目4個，長(chang)14.294公(gong)里(li)；云(yun)南玉磨鐵(tie)路隧道工(gong)程(cheng)1#斜井(jing)及主洞(dong)開(kai)挖支護工(gong)程(cheng)1項(xiang)。

二是科技創新(xin)和生(sheng)(sheng)(sheng)產(chan)經(jing)營取(qu)得(de)“雙(shuang)豐收”。2016年，針對上海海綿城(cheng)市埋深超(chao)70米、地連(lian)墻垂直度掌控(kong)難(nan)度大(da)的(de)施(shi)工(gong)難(nan)題，開展(zhan)(zhan)海綿城(cheng)市大(da)直徑垂直井凍(dong)(dong)結(jie)法(fa)(fa)施(shi)工(gong)研究，將(jiang)凍(dong)(dong)結(jie)法(fa)(fa)推廣應(ying)用(yong)于海綿城(cheng)市垂直井施(shi)工(gong)，成(cheng)為上海海綿城(cheng)市建設唯一一家(jia)合(he)作(zuo)單位。研發(fa)了(le)(le)清(qing)水模板工(gong)藝，并成(cheng)功(gong)在上海、常州等8個工(gong)地應(ying)用(yong)，提(ti)高(gao)(gao)了(le)(le)企(qi)業(ye)品牌形(xing)象。自行(xing)研制的(de)打鉆簡(jian)易操作(zuo)平臺，既提(ti)高(gao)(gao)生(sheng)(sheng)(sheng)產(chan)效率、降低了(le)(le)生(sheng)(sheng)(sheng)產(chan)成(cheng)本(ben)，又(you)促進(jin)了(le)(le)安全生(sheng)(sheng)(sheng)產(chan)、文明施(shi)工(gong)。首次應(ying)用(yong)凍(dong)(dong)結(jie)站云(yun)平臺監(jian)控(kong)系統，提(ti)高(gao)(gao)了(le)(le)凍(dong)(dong)結(jie)施(shi)工(gong)的(de)安全可控(kong)度。研發(fa)了(le)(le)水平鉆孔(kong)高(gao)(gao)壓(ya)防噴裝(zhuang)置，開展(zhan)(zhan)了(le)(le)大(da)體積凍(dong)(dong)土(tu)強制解凍(dong)(dong)融(rong)沉注漿先(xian)期試驗。全年取(qu)得(de)2項(xiang)國家(jia)發(fa)明專(zhuan)利授權。同時，完(wan)成(cheng)地鐵隧(sui)道(dao)(dao)施(shi)工(gong)5000米；提(ti)前60天實現延(yan)安隧(sui)道(dao)(dao)雙(shuang)線精準貫通；凍(dong)(dong)結(jie)工(gong)程等項(xiang)目圓滿完(wan)成(cheng)施(shi)工(gong)進(jin)度目標(biao)；取(qu)得(de)良好的(de)經(jing)營業(ye)績(ji)。
