近年來，煤炭(tan)產能(neng)嚴(yan)重過(guo)剩，煤炭(tan)基建(jian)市(shi)場(chang)(chang)大幅(fu)萎縮(suo)(suo)。特(te)別是隨著國家供(gong)給側結(jie)構(gou)性改革和(he)煤炭(tan)去產能(neng)的深入(ru)推(tui)進，煤炭(tan)基建(jian)市(shi)場(chang)(chang)進一步(bu)萎縮(suo)(suo)。面(mian)對嚴(yan)峻形勢，中煤集團五建(jian)公(gong)司發(fa)揮企業施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)技術優勢，著力把礦(kuang)建(jian)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)技術引入(ru)地(di)鐵(tie)隧(sui)道(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)領(ling)域(yu)，加快向地(di)鐵(tie)隧(sui)道(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)領(ling)域(yu)轉型，廣泛(fan)開(kai)(kai)展市(shi)政公(gong)用工(gong)(gong)(gong)(gong)程(cheng)、隧(sui)道(dao)工(gong)(gong)(gong)(gong)程(cheng)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)業務，在(zai)(zai)盾(dun)構(gou)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)、凍結(jie)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)和(he)隧(sui)道(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)方面(mian)積累了豐富(fu)的經驗，在(zai)(zai)市(shi)場(chang)(chang)開(kai)(kai)發(fa)、科技創(chuang)新(xin)和(he)管理創(chuang)新(xin)方面(mian)成果(guo)豐碩。截至(zhi)目前，該公(gong)司通過(guo)專業分包(bao)的方式，先后在(zai)(zai)上(shang)海、南京(jing)、寧波、天津、合肥累計完(wan)成地(di)鐵(tie)隧(sui)道(dao)盾(dun)構(gou)推(tui)進46公(gong)里，現(xian)有昆(kun)明、武漢、天津、合肥等盾(dun)構(gou)項(xiang)目；通過(guo)發(fa)展BT模(mo)式，總承(cheng)包(bao)了延安市(shi)小砭(bian)溝長1.977公(gong)里公(gong)路及(ji)隧(sui)道(dao)工(gong)(gong)(gong)(gong)程(cheng)；通過(guo)將礦(kuang)建(jian)凍結(jie)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)技術引入(ru)城(cheng)市(shi)地(di)鐵(tie)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)領(ling)域(yu)，開(kai)(kai)展專業承(cheng)包(bao)方式，在(zai)(zai)6個(ge)城(cheng)市(shi)完(wan)成25個(ge)凍結(jie)項(xiang)目施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)。

一、發揮自身技術優勢(shi)，成功打入地鐵隧道施工市(shi)場

近年(nian)來，中(zhong)煤集團五建(jian)公司發揮礦建(jian)立井凍結(jie)施工(gong)(gong)(gong)技(ji)術優勢，從(cong)其他地鐵(tie)隧道(dao)(dao)(dao)施工(gong)(gong)(gong)企業最(zui)薄弱而自身最(zui)擅長的(de)凍結(jie)施工(gong)(gong)(gong)入(ru)手，成功進入(ru)城市地鐵(tie)隧道(dao)(dao)(dao)旁通道(dao)(dao)(dao)施工(gong)(gong)(gong)，擠進地鐵(tie)隧道(dao)(dao)(dao)施工(gong)(gong)(gong)分包市場(chang)，推動了技(ji)術創新和轉型發展。

在凍(dong)結(jie)施(shi)(shi)工(gong)方(fang)面，地鐵(tie)隧道凍(dong)結(jie)施(shi)(shi)工(gong)能力保持(chi)行業領先水(shui)平，搶(qiang)占了(le)全(quan)國(guo)地鐵(tie)隧道凍(dong)結(jie)施(shi)(shi)工(gong)市場份額1/3。獨有(you)的平行作業施(shi)(shi)工(gong)、始發接收(shou)段全(quan)封(feng)閉水(shui)平凍(dong)結(jie)加固工(gong)法被評為(wei)(wei)省部級工(gong)法，并獲施(shi)(shi)工(gong)企業管理協會科學技術創新成(cheng)(cheng)果二等獎(jiang)；授權(quan)發明專(zhuan)利3項(xiang)、實用新型專(zhuan)利13項(xiang)；已成(cheng)(cheng)長為(wei)(wei)長三(san)角地區地鐵(tie)旁通道施(shi)(shi)工(gong)的主力企業。

在盾(dun)(dun)(dun)(dun)構(gou)施(shi)工(gong)方面，熟練(lian)掌握了土壓平衡盾(dun)(dun)(dun)(dun)構(gou)在各種復雜環境下盾(dun)(dun)(dun)(dun)構(gou)推(tui)進(jin)(jin)施(shi)工(gong)技術、復合盾(dun)(dun)(dun)(dun)構(gou)推(tui)進(jin)(jin)施(shi)工(gong)技術。其中，無鉸(jiao)接盾(dun)(dun)(dun)(dun)構(gou)極限(xian)小曲率半(ban)徑施(shi)工(gong)法被評(ping)為省部級工(gong)法。盾(dun)(dun)(dun)(dun)構(gou)最(zui)高月度單進(jin)(jin)442.5米(mi)，雙(shuang)線同(tong)時(shi)推(tui)進(jin)(jin)月度最(zui)高進(jin)(jin)尺813米(mi)。

在隧(sui)道(dao)施(shi)工方面，在延安小砭溝公路隧(sui)道(dao)施(shi)工中，將(jiang)礦(kuang)山光面爆(bao)破技術成功應用于大斷面隧(sui)道(dao)施(shi)工，安全、質量(liang)、進度均得到業主(zhu)認(ren)可，獲得延安市市級文明工地(di)、陜(shan)西(xi)省(sheng)省(sheng)級文明工地(di)，正在申報陜(shan)西(xi)省(sheng)工程質量(liang)最高(gao)獎“長安杯(bei)”。

二、開拓創(chuang)新，轉(zhuan)型發展效果顯著

目前，該(gai)公(gong)司年(nian)可同(tong)時(shi)施(shi)(shi)工(gong)10條地(di)鐵盾構(gou)作業線，施(shi)(shi)工(gong)能(neng)力(li)近(jin)10公(gong)里；年(nian)可同(tong)時(shi)施(shi)(shi)工(gong)凍(dong)結(jie)工(gong)程(cheng)（聯絡(luo)通道(dao)、洞(dong)門）近(jin)百個；年(nian)可施(shi)(shi)工(gong)公(gong)路大斷面(mian)隧道(dao)工(gong)程(cheng)2-3個。

一是市場(chang)開(kai)發成效明顯。2016年，該公(gong)司(si)加大(da)市場(chang)開(kai)發力度，抓(zhua)住中(zhong)鐵(tie)隧道(dao)開(kai)拓中(zhong)立井(jing)建設(she)的弱項(xiang)，以現(xian)有(you)玉磨(mo)隧道(dao)豎井(jing)合作為(wei)契機，打造(zao)精(jing)品(pin)工(gong)(gong)程，不(bu)斷(duan)擴大(da)合作市場(chang)。大(da)力拓展(zhan)城市管廊、海(hai)綿城市建設(she)、老城地(di)(di)下管網改造(zao)等(deng)新興市政工(gong)(gong)程。通過不(bu)懈(xie)努力，該公(gong)司(si)全年承攬(lan)工(gong)(gong)程22項(xiang)。其中(zhong)，地(di)(di)鐵(tie)隧道(dao)旁通道(dao)37個(ge)(ge)、洞門加固凍結工(gong)(gong)程9個(ge)(ge)；盾(dun)構推進(jin)項(xiang)目4個(ge)(ge)，長14.294公(gong)里；云(yun)南玉磨(mo)鐵(tie)路(lu)隧道(dao)工(gong)(gong)程1#斜井(jing)及(ji)主洞開(kai)挖支護(hu)工(gong)(gong)程1項(xiang)。

二是科技創新和生(sheng)產經(jing)營(ying)取得“雙(shuang)(shuang)豐(feng)收(shou)”。2016年，針(zhen)對上海(hai)(hai)海(hai)(hai)綿城(cheng)市(shi)埋(mai)深超70米、地連墻(qiang)垂(chui)直度(du)(du)掌控(kong)難度(du)(du)大的施工(gong)難題，開(kai)(kai)展海(hai)(hai)綿城(cheng)市(shi)大直徑垂(chui)直井凍(dong)(dong)結法(fa)施工(gong)研(yan)究(jiu)，將凍(dong)(dong)結法(fa)推廣應用(yong)(yong)于海(hai)(hai)綿城(cheng)市(shi)垂(chui)直井施工(gong)，成(cheng)(cheng)為(wei)上海(hai)(hai)海(hai)(hai)綿城(cheng)市(shi)建設唯一一家(jia)合作單位。研(yan)發了(le)(le)清水(shui)模板工(gong)藝，并成(cheng)(cheng)功在上海(hai)(hai)、常州等(deng)8個工(gong)地應用(yong)(yong)，提高(gao)(gao)了(le)(le)企業品牌形象。自行研(yan)制的打鉆簡易操作平臺(tai)，既提高(gao)(gao)生(sheng)產效率、降低了(le)(le)生(sheng)產成(cheng)(cheng)本(ben)，又促(cu)進了(le)(le)安全生(sheng)產、文(wen)明(ming)施工(gong)。首次應用(yong)(yong)凍(dong)(dong)結站云(yun)平臺(tai)監控(kong)系統，提高(gao)(gao)了(le)(le)凍(dong)(dong)結施工(gong)的安全可(ke)控(kong)度(du)(du)。研(yan)發了(le)(le)水(shui)平鉆孔(kong)高(gao)(gao)壓防噴裝置，開(kai)(kai)展了(le)(le)大體積凍(dong)(dong)土(tu)強制解凍(dong)(dong)融(rong)沉(chen)注漿先期(qi)試驗。全年取得2項國(guo)家(jia)發明(ming)專利(li)授權(quan)。同時，完成(cheng)(cheng)地鐵隧道施工(gong)5000米；提前60天實現延安隧道雙(shuang)(shuang)線精準(zhun)貫(guan)通；凍(dong)(dong)結工(gong)程(cheng)等(deng)項目圓滿完成(cheng)(cheng)施工(gong)進度(du)(du)目標(biao)；取得良好的經(jing)營(ying)業績。
