中冶寶冶參與(yu)邯鄲市生態水網改造高級渠恢復趙王城(cheng)改線工程，目前(qian)，各項施工任(ren)務按施工計劃進展順利，質(zhi)量在控制之中。
邯鄲市生態水(shui)網改造高級(ji)渠恢(hui)復工(gong)(gong)(gong)程(cheng)，是邯鄲市政府根(gen)據城市發展的(de)(de)需要，對市西區(qu)太行山脈丘陵灌(guan)溉區(qu)域配套日益(yi)完善的(de)(de)整體規劃，是造福于民的(de)(de)工(gong)(gong)(gong)程(cheng)。中冶寶冶承擔高級(ji)渠恢(hui)復工(gong)(gong)(gong)程(cheng)趙(zhao)王城改線隧洞(dong)施工(gong)(gong)(gong)，施工(gong)(gong)(gong)工(gong)(gong)(gong)程(cheng)為(wei)總(zong)承包(bao)項目(mu)，采(cai)用(yong)頂管(guan)施工(gong)(gong)(gong)方(fang)案，管(guan)道長(chang)度為(wei)2000米，采(cai)用(yong)DN2600頂進(jin)施工(gong)(gong)(gong)，用(yong)鋼筋混凝土專用(yong)管(guan)道，埋(mai)深8—27米左(zuo)右。
高級渠恢復(fu)工(gong)程(cheng)趙王(wang)城改線(xian)隧道頂(ding)管(guan)(guan)工(gong)程(cheng)地(di)處地(di)層(ceng)復(fu)雜，為第三系沉積物和第四系松散沉積物，以(yi)粘土(tu)、亞(ya)(ya)粘土(tu)、亞(ya)(ya)砂(sha)土(tu)夾(jia)砂(sha)層(ceng)及(ji)礫(li)石層(ceng)為主(zhu)，給頂(ding)管(guan)(guan)施(shi)工(gong)帶來極大不便。中冶寶冶施(shi)工(gong)項目(mu)部克服各種不利(li)地(di)質(zhi)因素，在2公里長的(de)作業點采(cai)取多點開花、三個(ge)頂(ding)管(guan)(guan)井(jing)同時施(shi)工(gong)的(de)做法，保(bao)證施(shi)工(gong)在節(jie)點期內迅速展(zhan)開。面對由于地(di)質(zhi)條件的(de)復(fu)雜造成頂(ding)管(guan)(guan)井(jing)的(de)沉降(jiang)不均，項目(mu)部質(zhi)量技術人員就所(suo)遇到的(de)工(gong)程(cheng)問題進行(xing)攻關，并(bing)根據每個(ge)頂(ding)管(guan)(guan)井(jing)在施(shi)工(gong)過程(cheng)中所(suo)遇到的(de)不同土(tu)質(zhi)結(jie)構(gou)采(cai)取不同的(de)施(shi)工(gong)方法。特別(bie)是對2#沉井(jing)的(de)糾偏方式，項目(mu)部采(cai)用了(le)液壓頂(ding)及(ji)井(jing)外土(tu)方卸載相結(jie)合的(de)方式來使沉降(jiang)不均勻(yun)的(de)沉井(jing)均勻(yun)下沉。
中冶寶冶還對已施工(gong)(gong)的各(ge)(ge)個(ge)頂(ding)(ding)管(guan)井進(jin)行量進(jin)行質(zhi)量評價。經檢(jian)查，各(ge)(ge)個(ge)頂(ding)(ding)管(guan)井的施工(gong)(gong)質(zhi)量良好。在深基坑施工(gong)(gong)過程中采用寶鋼的標準對現場施工(gong)(gong)隊伍進(jin)行了管(guan)理，各(ge)(ge)項安全措施到位。目(mu)前，第一節段2號(hao)井－1號(hao)井頂(ding)(ding)管(guan)工(gong)(gong)程11月初開頂(ding)(ding)，頂(ding)(ding)管(guan)管(guan)材已經生產100條節。
