近年(nian)來，煤炭(tan)(tan)產(chan)能嚴重過剩(sheng)，煤炭(tan)(tan)基建(jian)市(shi)(shi)場(chang)大幅萎(wei)縮。特別是隨著國家供(gong)給側結(jie)(jie)構性改革和煤炭(tan)(tan)去產(chan)能的深入(ru)(ru)推(tui)進，煤炭(tan)(tan)基建(jian)市(shi)(shi)場(chang)進一步(bu)萎(wei)縮。面(mian)對嚴峻形勢(shi)，中煤集團五建(jian)公(gong)司(si)發(fa)揮企業(ye)施(shi)(shi)(shi)工(gong)(gong)(gong)技(ji)(ji)術(shu)優勢(shi)，著力把礦建(jian)施(shi)(shi)(shi)工(gong)(gong)(gong)技(ji)(ji)術(shu)引(yin)入(ru)(ru)地(di)鐵(tie)隧道(dao)(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)領域(yu)，加快(kuai)向地(di)鐵(tie)隧道(dao)(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)領域(yu)轉型，廣泛開(kai)展(zhan)(zhan)市(shi)(shi)政公(gong)用(yong)工(gong)(gong)(gong)程(cheng)、隧道(dao)(dao)工(gong)(gong)(gong)程(cheng)施(shi)(shi)(shi)工(gong)(gong)(gong)業(ye)務，在盾(dun)構施(shi)(shi)(shi)工(gong)(gong)(gong)、凍結(jie)(jie)施(shi)(shi)(shi)工(gong)(gong)(gong)和隧道(dao)(dao)施(shi)(shi)(shi)工(gong)(gong)(gong)方(fang)(fang)面(mian)積累(lei)了豐富的經驗，在市(shi)(shi)場(chang)開(kai)發(fa)、科(ke)技(ji)(ji)創新和管理創新方(fang)(fang)面(mian)成(cheng)果豐碩。截至目前，該(gai)公(gong)司(si)通過專業(ye)分(fen)包(bao)的方(fang)(fang)式(shi)，先后在上海、南京、寧波、天津、合肥(fei)累(lei)計(ji)完(wan)成(cheng)地(di)鐵(tie)隧道(dao)(dao)盾(dun)構推(tui)進46公(gong)里，現(xian)有昆明、武漢、天津、合肥(fei)等盾(dun)構項(xiang)目；通過發(fa)展(zhan)(zhan)BT模式(shi)，總承包(bao)了延安市(shi)(shi)小砭(bian)溝(gou)長1.977公(gong)里公(gong)路及隧道(dao)(dao)工(gong)(gong)(gong)程(cheng)；通過將(jiang)礦建(jian)凍結(jie)(jie)施(shi)(shi)(shi)工(gong)(gong)(gong)技(ji)(ji)術(shu)引(yin)入(ru)(ru)城(cheng)市(shi)(shi)地(di)鐵(tie)施(shi)(shi)(shi)工(gong)(gong)(gong)領域(yu)，開(kai)展(zhan)(zhan)專業(ye)承包(bao)方(fang)(fang)式(shi)，在6個城(cheng)市(shi)(shi)完(wan)成(cheng)25個凍結(jie)(jie)項(xiang)目施(shi)(shi)(shi)工(gong)(gong)(gong)。

一、發揮(hui)自身技(ji)術優勢(shi)，成功打入地鐵隧道施(shi)工(gong)市(shi)場(chang)

近年來，中煤集團五建(jian)公(gong)司發(fa)揮礦建(jian)立井凍結施工(gong)技(ji)術優勢，從其他(ta)地鐵隧(sui)道施工(gong)企業最(zui)薄弱而自身最(zui)擅長(chang)的(de)凍結施工(gong)入手，成(cheng)功進入城市(shi)地鐵隧(sui)道旁通道施工(gong)，擠進地鐵隧(sui)道施工(gong)分包市(shi)場，推動了技(ji)術創新和轉型(xing)發(fa)展(zhan)。

在凍結(jie)(jie)施(shi)工(gong)(gong)方面，地(di)鐵隧道凍結(jie)(jie)施(shi)工(gong)(gong)能力保(bao)持(chi)行業領先(xian)水平(ping)，搶占了全(quan)國地(di)鐵隧道凍結(jie)(jie)施(shi)工(gong)(gong)市場份額1/3。獨有的(de)平(ping)行作業施(shi)工(gong)(gong)、始發(fa)接收段全(quan)封閉(bi)水平(ping)凍結(jie)(jie)加固(gu)工(gong)(gong)法被評為省部級工(gong)(gong)法，并(bing)獲施(shi)工(gong)(gong)企業管理協會(hui)科學技術創新成果二(er)等獎；授權發(fa)明(ming)專(zhuan)利(li)3項、實(shi)用新型專(zhuan)利(li)13項；已(yi)成長為長三角地(di)區地(di)鐵旁通道施(shi)工(gong)(gong)的(de)主力企業。

在盾(dun)(dun)構施(shi)(shi)(shi)工方面，熟練掌握(wo)了土壓平衡盾(dun)(dun)構在各(ge)種復雜(za)環境(jing)下盾(dun)(dun)構推(tui)進(jin)施(shi)(shi)(shi)工技術(shu)、復合盾(dun)(dun)構推(tui)進(jin)施(shi)(shi)(shi)工技術(shu)。其中(zhong)，無(wu)鉸接盾(dun)(dun)構極(ji)限小曲率(lv)半徑施(shi)(shi)(shi)工法被評為省部級(ji)工法。盾(dun)(dun)構最高(gao)月度單進(jin)442.5米，雙線(xian)同時推(tui)進(jin)月度最高(gao)進(jin)尺813米。

在隧道(dao)(dao)施工(gong)(gong)方面(mian)(mian)，在延(yan)安小砭溝公路(lu)隧道(dao)(dao)施工(gong)(gong)中，將礦山(shan)光面(mian)(mian)爆破技術成功應用于大斷(duan)面(mian)(mian)隧道(dao)(dao)施工(gong)(gong)，安全(quan)、質(zhi)量、進度均得到(dao)業(ye)主認(ren)可，獲得延(yan)安市市級文明工(gong)(gong)地、陜西省省級文明工(gong)(gong)地，正(zheng)在申報(bao)陜西省工(gong)(gong)程(cheng)質(zhi)量最高獎“長安杯”。

二、開拓創新(xin)，轉型(xing)發展效果(guo)顯著

目前，該(gai)公司年可同(tong)時(shi)施工(gong)10條地鐵(tie)盾構作業線，施工(gong)能(neng)力近(jin)10公里；年可同(tong)時(shi)施工(gong)凍結工(gong)程(cheng)（聯絡通(tong)道、洞門）近(jin)百個(ge)；年可施工(gong)公路大斷面(mian)隧道工(gong)程(cheng)2-3個(ge)。

一是市(shi)場開(kai)(kai)發(fa)成效明顯。2016年(nian)，該公司(si)加(jia)大(da)市(shi)場開(kai)(kai)發(fa)力度，抓住中(zhong)鐵隧道(dao)開(kai)(kai)拓(tuo)中(zhong)立(li)井(jing)(jing)建(jian)設的弱(ruo)項(xiang)，以現有玉磨隧道(dao)豎井(jing)(jing)合作(zuo)為契機，打造精品工程(cheng)(cheng)(cheng)，不(bu)斷擴(kuo)大(da)合作(zuo)市(shi)場。大(da)力拓(tuo)展(zhan)城(cheng)市(shi)管廊、海綿城(cheng)市(shi)建(jian)設、老城(cheng)地下管網改造等新興(xing)市(shi)政工程(cheng)(cheng)(cheng)。通過不(bu)懈努力，該公司(si)全年(nian)承攬(lan)工程(cheng)(cheng)(cheng)22項(xiang)。其中(zhong)，地鐵隧道(dao)旁通道(dao)37個(ge)(ge)、洞(dong)門(men)加(jia)固(gu)凍(dong)結(jie)工程(cheng)(cheng)(cheng)9個(ge)(ge)；盾構(gou)推進項(xiang)目4個(ge)(ge)，長(chang)14.294公里；云南(nan)玉磨鐵路隧道(dao)工程(cheng)(cheng)(cheng)1#斜(xie)井(jing)(jing)及(ji)主洞(dong)開(kai)(kai)挖支護工程(cheng)(cheng)(cheng)1項(xiang)。

二是(shi)科(ke)技創新和生產(chan)(chan)經(jing)營取(qu)得(de)“雙豐(feng)收”。2016年，針對(dui)上(shang)(shang)海(hai)(hai)海(hai)(hai)綿(mian)城(cheng)市(shi)(shi)(shi)埋深超70米、地(di)連墻垂直度(du)(du)掌控難度(du)(du)大(da)的(de)施(shi)工(gong)(gong)難題，開展海(hai)(hai)綿(mian)城(cheng)市(shi)(shi)(shi)大(da)直徑垂直井(jing)凍(dong)結(jie)(jie)法(fa)施(shi)工(gong)(gong)研究，將凍(dong)結(jie)(jie)法(fa)推廣應用(yong)(yong)于海(hai)(hai)綿(mian)城(cheng)市(shi)(shi)(shi)垂直井(jing)施(shi)工(gong)(gong)，成(cheng)為上(shang)(shang)海(hai)(hai)海(hai)(hai)綿(mian)城(cheng)市(shi)(shi)(shi)建設(she)唯一(yi)一(yi)家合作(zuo)單(dan)位(wei)。研發了(le)清水模板工(gong)(gong)藝(yi)，并成(cheng)功在上(shang)(shang)海(hai)(hai)、常州等(deng)8個工(gong)(gong)地(di)應用(yong)(yong)，提高了(le)企業品牌形象。自行研制的(de)打鉆簡(jian)易操作(zuo)平臺，既提高生產(chan)(chan)效率、降低了(le)生產(chan)(chan)成(cheng)本，又促進了(le)安(an)全(quan)生產(chan)(chan)、文明施(shi)工(gong)(gong)。首次應用(yong)(yong)凍(dong)結(jie)(jie)站云平臺監控系統，提高了(le)凍(dong)結(jie)(jie)施(shi)工(gong)(gong)的(de)安(an)全(quan)可控度(du)(du)。研發了(le)水平鉆孔高壓(ya)防噴裝(zhuang)置(zhi)，開展了(le)大(da)體積凍(dong)土強制解凍(dong)融沉注漿先(xian)期(qi)試驗。全(quan)年取(qu)得(de)2項國家發明專利授權。同時(shi)，完成(cheng)地(di)鐵隧道(dao)施(shi)工(gong)(gong)5000米；提前60天實現延安(an)隧道(dao)雙線(xian)精準貫(guan)通；凍(dong)結(jie)(jie)工(gong)(gong)程等(deng)項目圓滿(man)完成(cheng)施(shi)工(gong)(gong)進度(du)(du)目標；取(qu)得(de)良好的(de)經(jing)營業績。
