近年來，煤(mei)(mei)炭產能嚴(yan)重過剩，煤(mei)(mei)炭基建(jian)市(shi)場大幅萎(wei)縮。特(te)別是(shi)隨(sui)著國(guo)家供給側結(jie)(jie)(jie)構性改革(ge)和(he)(he)煤(mei)(mei)炭去產能的(de)深入推(tui)進(jin)(jin)，煤(mei)(mei)炭基建(jian)市(shi)場進(jin)(jin)一步萎(wei)縮。面(mian)對嚴(yan)峻形勢，中煤(mei)(mei)集團五(wu)建(jian)公(gong)(gong)司(si)發(fa)揮企業(ye)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)技術(shu)優勢，著力把(ba)礦建(jian)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)技術(shu)引(yin)入地(di)鐵(tie)隧(sui)道(dao)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)領域(yu)(yu)，加快向地(di)鐵(tie)隧(sui)道(dao)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)領域(yu)(yu)轉(zhuan)型，廣(guang)泛開展(zhan)市(shi)政公(gong)(gong)用工(gong)(gong)(gong)程、隧(sui)道(dao)工(gong)(gong)(gong)程施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)業(ye)務(wu)，在盾構施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)、凍(dong)結(jie)(jie)(jie)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)和(he)(he)隧(sui)道(dao)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)方(fang)(fang)面(mian)積累(lei)了豐富的(de)經驗，在市(shi)場開發(fa)、科技創新(xin)和(he)(he)管理創新(xin)方(fang)(fang)面(mian)成(cheng)果(guo)豐碩。截至目(mu)前(qian)，該(gai)公(gong)(gong)司(si)通過專業(ye)分(fen)包(bao)的(de)方(fang)(fang)式(shi)(shi)，先后在上海(hai)、南(nan)京、寧波、天(tian)津(jin)、合(he)肥(fei)累(lei)計完成(cheng)地(di)鐵(tie)隧(sui)道(dao)盾構推(tui)進(jin)(jin)46公(gong)(gong)里，現有昆明、武漢(han)、天(tian)津(jin)、合(he)肥(fei)等(deng)盾構項(xiang)目(mu)；通過發(fa)展(zhan)BT模(mo)式(shi)(shi)，總(zong)承包(bao)了延安市(shi)小砭溝長1.977公(gong)(gong)里公(gong)(gong)路及(ji)隧(sui)道(dao)工(gong)(gong)(gong)程；通過將(jiang)礦建(jian)凍(dong)結(jie)(jie)(jie)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)技術(shu)引(yin)入城市(shi)地(di)鐵(tie)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)領域(yu)(yu)，開展(zhan)專業(ye)承包(bao)方(fang)(fang)式(shi)(shi)，在6個城市(shi)完成(cheng)25個凍(dong)結(jie)(jie)(jie)項(xiang)目(mu)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)。

一(yi)、發揮自身技術優(you)勢(shi)，成功打入地(di)鐵隧道施工市場

近年來，中煤集(ji)團五(wu)建公司發揮礦建立井凍(dong)結(jie)施工技術優勢，從其(qi)他(ta)地鐵隧(sui)(sui)道施工企業最(zui)薄弱而自(zi)身最(zui)擅長的(de)凍(dong)結(jie)施工入(ru)手(shou)，成(cheng)功進入(ru)城市地鐵隧(sui)(sui)道旁通(tong)道施工，擠進地鐵隧(sui)(sui)道施工分包市場，推動了技術創新和轉型發展。

在凍(dong)結施(shi)(shi)(shi)工(gong)(gong)方面(mian)，地(di)(di)鐵(tie)隧(sui)道(dao)凍(dong)結施(shi)(shi)(shi)工(gong)(gong)能力(li)保持行業(ye)(ye)領(ling)先水平(ping)，搶占了全國(guo)地(di)(di)鐵(tie)隧(sui)道(dao)凍(dong)結施(shi)(shi)(shi)工(gong)(gong)市場份(fen)額1/3。獨有的平(ping)行作業(ye)(ye)施(shi)(shi)(shi)工(gong)(gong)、始發接收段全封閉(bi)水平(ping)凍(dong)結加固工(gong)(gong)法被評為省部級工(gong)(gong)法，并(bing)獲施(shi)(shi)(shi)工(gong)(gong)企(qi)業(ye)(ye)管理(li)協會(hui)科學技術創新(xin)(xin)成果二等獎；授(shou)權(quan)發明專(zhuan)利3項(xiang)、實用新(xin)(xin)型(xing)專(zhuan)利13項(xiang)；已(yi)成長為長三角地(di)(di)區地(di)(di)鐵(tie)旁通道(dao)施(shi)(shi)(shi)工(gong)(gong)的主力(li)企(qi)業(ye)(ye)。

在盾構施(shi)(shi)工方面，熟練掌握了土壓平衡盾構在各種復雜環境下盾構推(tui)進(jin)(jin)(jin)施(shi)(shi)工技術(shu)、復合盾構推(tui)進(jin)(jin)(jin)施(shi)(shi)工技術(shu)。其中，無鉸(jiao)接(jie)盾構極限(xian)小曲(qu)率半徑施(shi)(shi)工法被(bei)評為省部級工法。盾構最高月(yue)度單進(jin)(jin)(jin)442.5米，雙線同時推(tui)進(jin)(jin)(jin)月(yue)度最高進(jin)(jin)(jin)尺813米。

在(zai)隧道施工(gong)方面(mian)(mian)，在(zai)延安小砭溝公路(lu)隧道施工(gong)中，將礦山光面(mian)(mian)爆破(po)技術成功應用于大斷面(mian)(mian)隧道施工(gong)，安全(quan)、質量(liang)(liang)、進(jin)度均(jun)得到業主認(ren)可，獲得延安市市級文明工(gong)地(di)、陜(shan)(shan)西(xi)省(sheng)省(sheng)級文明工(gong)地(di)，正在(zai)申報(bao)陜(shan)(shan)西(xi)省(sheng)工(gong)程質量(liang)(liang)最高獎“長(chang)安杯”。

二、開拓創新，轉型(xing)發展(zhan)效果顯(xian)著

目前，該公(gong)(gong)司年(nian)(nian)可同時(shi)(shi)施(shi)工(gong)10條地(di)鐵盾構作業線，施(shi)工(gong)能力近(jin)10公(gong)(gong)里；年(nian)(nian)可同時(shi)(shi)施(shi)工(gong)凍結工(gong)程(cheng)（聯絡(luo)通道(dao)、洞(dong)門）近(jin)百個(ge)；年(nian)(nian)可施(shi)工(gong)公(gong)(gong)路大斷面隧(sui)道(dao)工(gong)程(cheng)2-3個(ge)。

一(yi)是(shi)市場(chang)開(kai)發成效明顯(xian)。2016年，該公(gong)司加大(da)市場(chang)開(kai)發力度(du)，抓住中鐵(tie)隧道(dao)開(kai)拓中立井建設的弱項(xiang)，以現有玉磨隧道(dao)豎井合(he)作為(wei)契機(ji)，打(da)造(zao)(zao)精品(pin)工(gong)程，不斷擴大(da)合(he)作市場(chang)。大(da)力拓展城(cheng)市管廊、海綿城(cheng)市建設、老(lao)城(cheng)地(di)下管網改造(zao)(zao)等新興市政工(gong)程。通(tong)過不懈(xie)努力，該公(gong)司全(quan)年承攬工(gong)程22項(xiang)。其(qi)中，地(di)鐵(tie)隧道(dao)旁通(tong)道(dao)37個、洞門(men)加固凍(dong)結(jie)工(gong)程9個；盾構推進項(xiang)目4個，長14.294公(gong)里；云南玉磨鐵(tie)路隧道(dao)工(gong)程1#斜井及主(zhu)洞開(kai)挖支(zhi)護工(gong)程1項(xiang)。

二是(shi)科技創新和生產(chan)經營取(qu)得(de)“雙(shuang)豐收”。2016年(nian)，針對上海(hai)海(hai)綿(mian)城(cheng)市埋深超70米(mi)、地連墻垂(chui)(chui)直度(du)(du)(du)掌控難(nan)度(du)(du)(du)大(da)的(de)施工(gong)難(nan)題，開展海(hai)綿(mian)城(cheng)市大(da)直徑(jing)垂(chui)(chui)直井(jing)凍(dong)(dong)結法施工(gong)研究(jiu)，將凍(dong)(dong)結法推廣應(ying)用(yong)于海(hai)綿(mian)城(cheng)市垂(chui)(chui)直井(jing)施工(gong)，成為(wei)上海(hai)海(hai)綿(mian)城(cheng)市建(jian)設唯(wei)一一家合作單位。研發了清水(shui)模板工(gong)藝，并成功(gong)在上海(hai)、常州等(deng)8個工(gong)地應(ying)用(yong)，提(ti)高(gao)(gao)了企業品牌形象。自行(xing)研制(zhi)的(de)打鉆(zhan)簡易操(cao)作平(ping)臺，既(ji)提(ti)高(gao)(gao)生產(chan)效率、降低(di)了生產(chan)成本，又促進了安全(quan)生產(chan)、文明施工(gong)。首次應(ying)用(yong)凍(dong)(dong)結站云(yun)平(ping)臺監控系(xi)統，提(ti)高(gao)(gao)了凍(dong)(dong)結施工(gong)的(de)安全(quan)可控度(du)(du)(du)。研發了水(shui)平(ping)鉆(zhan)孔高(gao)(gao)壓防噴裝置，開展了大(da)體(ti)積凍(dong)(dong)土(tu)強制(zhi)解凍(dong)(dong)融(rong)沉注漿先(xian)期(qi)試驗。全(quan)年(nian)取(qu)得(de)2項國(guo)家發明專利授權。同時，完成地鐵隧道(dao)施工(gong)5000米(mi)；提(ti)前60天實現延安隧道(dao)雙(shuang)線(xian)精準貫通；凍(dong)(dong)結工(gong)程等(deng)項目(mu)圓滿(man)完成施工(gong)進度(du)(du)(du)目(mu)標(biao)；取(qu)得(de)良好(hao)的(de)經營業績。
