中(zhong)冶(ye)寶(bao)冶(ye)參與邯(han)鄲(dan)市生態水網改(gai)造高級渠恢復趙(zhao)王城改(gai)線工(gong)程，目前，各項施工(gong)任務按施工(gong)計劃進展順(shun)利，質量在控制之中(zhong)。
邯(han)鄲市(shi)生態水網改(gai)造(zao)高級渠(qu)恢復工(gong)程(cheng)，是邯(han)鄲市(shi)政(zheng)府根據城市(shi)發展的(de)需要，對(dui)市(shi)西(xi)區太行山脈(mo)丘(qiu)陵灌溉(gai)區域配套日(ri)益完善的(de)整體(ti)規(gui)劃，是造(zao)福于民的(de)工(gong)程(cheng)。中冶(ye)寶冶(ye)承擔高級渠(qu)恢復工(gong)程(cheng)趙王城改(gai)線隧(sui)洞施工(gong)，施工(gong)工(gong)程(cheng)為(wei)總承包項目，采(cai)用頂管(guan)施工(gong)方案，管(guan)道(dao)長度(du)為(wei)2000米，采(cai)用DN2600頂進施工(gong)，用鋼(gang)筋混(hun)凝土專用管(guan)道(dao)，埋(mai)深(shen)8—27米左(zuo)右(you)。
高級渠恢復工(gong)(gong)(gong)程(cheng)趙王城改線隧道頂(ding)管(guan)工(gong)(gong)(gong)程(cheng)地(di)處(chu)地(di)層(ceng)復雜(za)，為第(di)三(san)系沉(chen)積(ji)物(wu)和第(di)四系松散沉(chen)積(ji)物(wu)，以(yi)粘土(tu)、亞(ya)粘土(tu)、亞(ya)砂土(tu)夾砂層(ceng)及礫(li)石層(ceng)為主(zhu)，給頂(ding)管(guan)施(shi)(shi)工(gong)(gong)(gong)帶來極大不(bu)(bu)(bu)便。中冶寶冶施(shi)(shi)工(gong)(gong)(gong)項目部(bu)克服各種不(bu)(bu)(bu)利地(di)質(zhi)(zhi)因素(su)，在2公(gong)里長的(de)(de)作業(ye)點采(cai)取(qu)多點開(kai)花、三(san)個頂(ding)管(guan)井(jing)同(tong)時(shi)施(shi)(shi)工(gong)(gong)(gong)的(de)(de)做法，保(bao)證施(shi)(shi)工(gong)(gong)(gong)在節點期內迅速展開(kai)。面(mian)對(dui)由(you)于地(di)質(zhi)(zhi)條(tiao)件的(de)(de)復雜(za)造成(cheng)頂(ding)管(guan)井(jing)的(de)(de)沉(chen)降(jiang)不(bu)(bu)(bu)均，項目部(bu)質(zhi)(zhi)量技術人員(yuan)就所遇到的(de)(de)工(gong)(gong)(gong)程(cheng)問題進行攻(gong)關，并根據每(mei)個頂(ding)管(guan)井(jing)在施(shi)(shi)工(gong)(gong)(gong)過(guo)程(cheng)中所遇到的(de)(de)不(bu)(bu)(bu)同(tong)土(tu)質(zhi)(zhi)結構采(cai)取(qu)不(bu)(bu)(bu)同(tong)的(de)(de)施(shi)(shi)工(gong)(gong)(gong)方(fang)(fang)法。特別是對(dui)2#沉(chen)井(jing)的(de)(de)糾偏方(fang)(fang)式(shi)，項目部(bu)采(cai)用了(le)液壓頂(ding)及井(jing)外土(tu)方(fang)(fang)卸載相結合的(de)(de)方(fang)(fang)式(shi)來使(shi)沉(chen)降(jiang)不(bu)(bu)(bu)均勻的(de)(de)沉(chen)井(jing)均勻下沉(chen)。
中(zhong)冶寶冶還對已(yi)施(shi)工(gong)(gong)(gong)的各個(ge)(ge)頂管(guan)井(jing)進行量(liang)進行質量(liang)評價。經(jing)檢查(cha)，各個(ge)(ge)頂管(guan)井(jing)的施(shi)工(gong)(gong)(gong)質量(liang)良(liang)好(hao)。在深基坑施(shi)工(gong)(gong)(gong)過(guo)程(cheng)中(zhong)采用(yong)寶鋼的標準對現場施(shi)工(gong)(gong)(gong)隊伍進行了(le)管(guan)理，各項安全措施(shi)到位。目(mu)前，第一節(jie)段2號(hao)(hao)井(jing)－1號(hao)(hao)井(jing)頂管(guan)工(gong)(gong)(gong)程(cheng)11月(yue)初開頂，頂管(guan)管(guan)材已(yi)經(jing)生(sheng)產100條節(jie)。
