今年以(yi)來，中國(guo)鐵建(jian)中鐵十九局(ju)集團二公司(si)哈牡(mu)客(ke)專項目部針對威虎山隧道工(gong)程建(jian)設中的難(nan)題，把科技創新作為施(shi)(shi)工(gong)“利(li)器”，廣泛采用(yong)新設備、新技術、新工(gong)藝，極大地加快了施(shi)(shi)工(gong)進度。
據了解，哈牡客(ke)運專(zhuan)線威虎山(shan)隧(sui)道(dao)工(gong)(gong)程(cheng)(cheng)線路全長7152米，是(shi)(shi)哈牡客(ke)專(zhuan)最早(zao)動(dong)工(gong)(gong)的(de)節點工(gong)(gong)程(cheng)(cheng)，也是(shi)(shi)重點、難點工(gong)(gong)程(cheng)(cheng)之一。項(xiang)目(mu)經理楊保(bao)旭(xu)介紹，面(mian)對工(gong)(gong)程(cheng)(cheng)地(di)質條件復雜，工(gong)(gong)期緊等難題，項(xiang)目(mu)部組建以21人為主力的(de)科研(yan)攻關團(tuan)隊，分(fen)(fen)成(cheng)三個小組，在(zai)隧(sui)道(dao)、橋梁等工(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)方面(mian)發(fa)起(qi)科研(yan)創(chuang)(chuang)(chuang)新(xin)(xin)攻關，先后研(yan)發(fa)出《移(yi)動(dong)式隧(sui)道(dao)仰(yang)(yang)(yang)(yang)拱(gong)模架》、隧(sui)道(dao)《新(xin)(xin)型液壓式二襯模板臺(tai)車》等五項(xiang)科研(yan)創(chuang)(chuang)(chuang)新(xin)(xin)成(cheng)果，解決了施(shi)(shi)工(gong)(gong)中(zhong)的(de)關鍵性技術難題，加快(kuai)了施(shi)(shi)工(gong)(gong)進度。《移(yi)動(dong)式隧(sui)道(dao)仰(yang)(yang)(yang)(yang)拱(gong)模架》科技創(chuang)(chuang)(chuang)新(xin)(xin)施(shi)(shi)工(gong)(gong)技術，配備可移(yi)動(dong)式12米長的(de)仰(yang)(yang)(yang)(yang)拱(gong)模架，在(zai)仰(yang)(yang)(yang)(yang)拱(gong)與二襯邊(bian)墻連接(jie)處設(she)置寬3米的(de)弧整體模板，滿足了仰(yang)(yang)(yang)(yang)拱(gong)砼一次澆筑(zhu)成(cheng)形(xing)的(de)施(shi)(shi)工(gong)(gong)要求，與傳統拼模相比，節省時間三分(fen)(fen)之一，減少(shao)拆裝次數。同時還杜絕(jue)了仰(yang)(yang)(yang)(yang)拱(gong)錯臺(tai)超(chao)限(xian)情況發(fa)生，為縮短仰(yang)(yang)(yang)(yang)拱(gong)循環作業次數提供技術支持。
為確保(bao)虎峰嶺隧(sui)道(dao)工(gong)(gong)期目(mu)標實現(xian)，項目(mu)部配備了國(guo)內最(zui)先進(jin)的(de)三臂鑿巖開挖臺(tai)車、噴漿機(ji)(ji)、自行(xing)(xing)式移(yi)動棧橋等各類設備共(gong)計100余臺(tai)套(tao)。目(mu)前，各科研成果都(dou)已在(zai)工(gong)(gong)程施工(gong)(gong)生產中(zhong)發揮主力(li)軍作用，其(qi)中(zhong)僅隧(sui)道(dao)施工(gong)(gong)采取的(de)全新濕(shi)噴工(gong)(gong)藝，全線就購置了4臺(tai)大(da)型(xing)的(de)濕(shi)噴機(ji)(ji)械手臂，還包括一些水溝電(dian)纜(lan)槽的(de)一個整體性臺(tai)車。另外，作為哈(ha)牡客專的(de)必(bi)備材料鋼構件加工(gong)(gong)廠(chang)，也(ye)大(da)力(li)推行(xing)(xing)安全生產標準化(hua)建設工(gong)(gong)作，使工(gong)(gong)程建設的(de)安全生產進(jin)一步規范化(hua)和標準化(hua)，生產水平得到(dao)不斷(duan)提升。
哈(ha)牡客專項目正按(an)照機械化、快速、高(gao)效(xiao)、節約(yue)人工的(de)(de)建設目標(biao)，力求(qiu)在最短工期內保證威虎山隧(sui)道的(de)(de)貫(guan)通，為哈(ha)牡客專全線的(de)(de)早日完工奠定良好基礎。
