中(zhong)冶寶冶參與邯鄲(dan)市生態(tai)水網改(gai)造高(gao)級渠恢復趙(zhao)王城(cheng)改(gai)線工(gong)程，目前，各項施工(gong)任務按施工(gong)計劃進(jin)展順利，質(zhi)量在(zai)控制之中(zhong)。
邯鄲市生態(tai)水網改(gai)造高級(ji)渠(qu)(qu)恢復工(gong)(gong)(gong)程，是邯鄲市政府根據城市發展的需要，對市西(xi)區太行山(shan)脈丘陵灌(guan)溉區域(yu)配套日益完善的整體規劃，是造福于(yu)民的工(gong)(gong)(gong)程。中(zhong)冶寶冶承(cheng)擔高級(ji)渠(qu)(qu)恢復工(gong)(gong)(gong)程趙王城改(gai)線隧洞(dong)施工(gong)(gong)(gong)，施工(gong)(gong)(gong)工(gong)(gong)(gong)程為(wei)總承(cheng)包項(xiang)目，采(cai)用頂管施工(gong)(gong)(gong)方案，管道長度為(wei)2000米(mi)，采(cai)用DN2600頂進施工(gong)(gong)(gong)，用鋼筋混凝土專用管道，埋深8—27米(mi)左(zuo)右。
高(gao)級渠(qu)恢復工(gong)(gong)(gong)程趙王城改(gai)線隧道頂(ding)管(guan)工(gong)(gong)(gong)程地(di)處(chu)地(di)層(ceng)復雜(za)，為第(di)三系(xi)沉(chen)積物(wu)(wu)和第(di)四系(xi)松散沉(chen)積物(wu)(wu)，以粘土(tu)、亞粘土(tu)、亞砂土(tu)夾砂層(ceng)及(ji)礫石(shi)層(ceng)為主(zhu)，給頂(ding)管(guan)施(shi)(shi)工(gong)(gong)(gong)帶來極大不(bu)便。中(zhong)冶(ye)寶冶(ye)施(shi)(shi)工(gong)(gong)(gong)項目(mu)部克服各種(zhong)不(bu)利地(di)質(zhi)(zhi)因素(su)，在(zai)(zai)2公里(li)長的(de)作業點采取多點開花、三個(ge)頂(ding)管(guan)井(jing)(jing)(jing)同時施(shi)(shi)工(gong)(gong)(gong)的(de)做法(fa)，保(bao)證施(shi)(shi)工(gong)(gong)(gong)在(zai)(zai)節點期內迅速展開。面對(dui)由(you)于地(di)質(zhi)(zhi)條(tiao)件的(de)復雜(za)造成頂(ding)管(guan)井(jing)(jing)(jing)的(de)沉(chen)降不(bu)均(jun)，項目(mu)部質(zhi)(zhi)量技(ji)術人(ren)員就所遇(yu)到的(de)工(gong)(gong)(gong)程問題進行攻關，并(bing)根據每個(ge)頂(ding)管(guan)井(jing)(jing)(jing)在(zai)(zai)施(shi)(shi)工(gong)(gong)(gong)過(guo)程中(zhong)所遇(yu)到的(de)不(bu)同土(tu)質(zhi)(zhi)結(jie)構采取不(bu)同的(de)施(shi)(shi)工(gong)(gong)(gong)方法(fa)。特別是對(dui)2#沉(chen)井(jing)(jing)(jing)的(de)糾偏方式，項目(mu)部采用(yong)了液(ye)壓頂(ding)及(ji)井(jing)(jing)(jing)外土(tu)方卸載相結(jie)合(he)的(de)方式來使沉(chen)降不(bu)均(jun)勻(yun)的(de)沉(chen)井(jing)(jing)(jing)均(jun)勻(yun)下沉(chen)。
中冶寶(bao)冶還對(dui)已(yi)施工(gong)(gong)的(de)(de)各(ge)個頂(ding)管井進(jin)行量(liang)進(jin)行質量(liang)評價。經檢(jian)查(cha)，各(ge)個頂(ding)管井的(de)(de)施工(gong)(gong)質量(liang)良好(hao)。在(zai)深(shen)基(ji)坑(keng)施工(gong)(gong)過程(cheng)中采用寶(bao)鋼的(de)(de)標準對(dui)現場施工(gong)(gong)隊伍進(jin)行了管理，各(ge)項安全措施到(dao)位。目前，第(di)一節(jie)段2號(hao)井－1號(hao)井頂(ding)管工(gong)(gong)程(cheng)11月初開頂(ding)，頂(ding)管管材已(yi)經生產100條節(jie)。
