今年以來，中國鐵(tie)建中鐵(tie)十九(jiu)局集(ji)團二公(gong)司哈牡(mu)客專項目部針(zhen)對(dui)威虎(hu)山隧道工(gong)程(cheng)建設(she)中的難題，把科(ke)技(ji)創新作為(wei)施工(gong)“利器(qi)”，廣泛采用新設(she)備、新技(ji)術、新工(gong)藝，極大地加快了施工(gong)進度。
據了(le)解，哈牡客(ke)運(yun)專(zhuan)線威虎山隧(sui)(sui)道(dao)(dao)工(gong)(gong)(gong)程線路全長(chang)7152米(mi)，是(shi)哈牡客(ke)專(zhuan)最早動(dong)(dong)工(gong)(gong)(gong)的(de)節(jie)點(dian)(dian)工(gong)(gong)(gong)程，也是(shi)重點(dian)(dian)、難點(dian)(dian)工(gong)(gong)(gong)程之一(yi)。項(xiang)目經理楊保旭介紹，面對工(gong)(gong)(gong)程地質條件復雜，工(gong)(gong)(gong)期(qi)緊等(deng)(deng)難題(ti)，項(xiang)目部組建以(yi)21人為主力的(de)科(ke)研(yan)(yan)攻關(guan)(guan)團隊(dui)，分成三個小組，在隧(sui)(sui)道(dao)(dao)、橋(qiao)梁等(deng)(deng)工(gong)(gong)(gong)程施工(gong)(gong)(gong)方面發起科(ke)研(yan)(yan)創(chuang)新攻關(guan)(guan)，先后(hou)研(yan)(yan)發出《移(yi)動(dong)(dong)式(shi)隧(sui)(sui)道(dao)(dao)仰(yang)拱(gong)模(mo)架(jia)》、隧(sui)(sui)道(dao)(dao)《新型液壓(ya)式(shi)二襯模(mo)板(ban)臺車》等(deng)(deng)五項(xiang)科(ke)研(yan)(yan)創(chuang)新成果，解決了(le)施工(gong)(gong)(gong)中的(de)關(guan)(guan)鍵性技(ji)術(shu)難題(ti)，加快了(le)施工(gong)(gong)(gong)進(jin)度(du)。《移(yi)動(dong)(dong)式(shi)隧(sui)(sui)道(dao)(dao)仰(yang)拱(gong)模(mo)架(jia)》科(ke)技(ji)創(chuang)新施工(gong)(gong)(gong)技(ji)術(shu)，配備(bei)可移(yi)動(dong)(dong)式(shi)12米(mi)長(chang)的(de)仰(yang)拱(gong)模(mo)架(jia)，在仰(yang)拱(gong)與(yu)二襯邊墻連接處設置寬3米(mi)的(de)弧整(zheng)體(ti)模(mo)板(ban)，滿足(zu)了(le)仰(yang)拱(gong)砼一(yi)次(ci)澆筑成形的(de)施工(gong)(gong)(gong)要求，與(yu)傳統拼模(mo)相比，節(jie)省時(shi)間三分之一(yi)，減少拆裝(zhuang)次(ci)數。同時(shi)還杜絕了(le)仰(yang)拱(gong)錯臺超限情況(kuang)發生，為縮(suo)短仰(yang)拱(gong)循環(huan)作業次(ci)數提供技(ji)術(shu)支持。
為確保虎(hu)峰嶺隧道工(gong)(gong)期(qi)目標實(shi)現，項目部配備(bei)了國內最(zui)先進的(de)三臂鑿巖(yan)開挖臺(tai)車(che)、噴(pen)漿機、自行式移動棧橋等(deng)各類設備(bei)共計100余臺(tai)套。目前，各科研成(cheng)果都(dou)已在工(gong)(gong)程施工(gong)(gong)生產(chan)(chan)中發揮主(zhu)力軍作(zuo)用，其中僅隧道施工(gong)(gong)采取的(de)全(quan)新濕(shi)噴(pen)工(gong)(gong)藝，全(quan)線就購置了4臺(tai)大(da)型的(de)濕(shi)噴(pen)機械手(shou)臂，還包括一(yi)些水(shui)溝電纜槽(cao)的(de)一(yi)個整體性臺(tai)車(che)。另外(wai)，作(zuo)為哈牡客專的(de)必備(bei)材料鋼構件加工(gong)(gong)廠，也大(da)力推行安全(quan)生產(chan)(chan)標準(zhun)化建設工(gong)(gong)作(zuo)，使(shi)工(gong)(gong)程建設的(de)安全(quan)生產(chan)(chan)進一(yi)步規范化和標準(zhun)化，生產(chan)(chan)水(shui)平得到不(bu)斷(duan)提升(sheng)。
哈(ha)牡客(ke)專項目(mu)正按照機械化、快速、高效、節(jie)約人工的(de)建設目(mu)標，力求在最短工期內保證(zheng)威虎(hu)山隧道的(de)貫通，為哈(ha)牡客(ke)專全線(xian)的(de)早日完工奠定良好(hao)基(ji)礎。
