中(zhong)冶(ye)寶冶(ye)參與邯鄲(dan)市(shi)生態水(shui)網改造高級渠恢復趙王城改線工(gong)(gong)程，目(mu)前，各項施工(gong)(gong)任務按(an)施工(gong)(gong)計(ji)劃進展順利(li)，質量(liang)在(zai)控(kong)制之中(zhong)。
邯鄲(dan)市(shi)(shi)生態水(shui)網改造高級渠(qu)恢復(fu)工程，是邯鄲(dan)市(shi)(shi)政府根據城市(shi)(shi)發(fa)展的需要，對市(shi)(shi)西區(qu)太(tai)行山脈(mo)丘陵灌溉區(qu)域配套日益完善的整體規劃，是造福于民(min)的工程。中冶寶冶承擔高級渠(qu)恢復(fu)工程趙王城改線隧(sui)洞施(shi)(shi)工，施(shi)(shi)工工程為總承包項目(mu)，采(cai)用頂(ding)管(guan)施(shi)(shi)工方案，管(guan)道長度為2000米，采(cai)用DN2600頂(ding)進施(shi)(shi)工，用鋼筋混凝土(tu)專用管(guan)道，埋(mai)深8—27米左(zuo)右。
高(gao)級渠恢復(fu)工(gong)(gong)(gong)程趙王城改線隧道頂(ding)管(guan)(guan)(guan)工(gong)(gong)(gong)程地(di)處地(di)層復(fu)雜，為(wei)第三系沉(chen)積物和(he)第四系松散沉(chen)積物，以粘土(tu)、亞粘土(tu)、亞砂(sha)土(tu)夾砂(sha)層及礫石層為(wei)主，給頂(ding)管(guan)(guan)(guan)施(shi)工(gong)(gong)(gong)帶來(lai)極大不便。中冶寶冶施(shi)工(gong)(gong)(gong)項(xiang)目(mu)部(bu)克服(fu)各種不利地(di)質(zhi)因素，在2公里(li)長的(de)(de)(de)作業點采(cai)取多點開花、三個(ge)頂(ding)管(guan)(guan)(guan)井(jing)(jing)同(tong)時施(shi)工(gong)(gong)(gong)的(de)(de)(de)做(zuo)法(fa)(fa)，保(bao)證施(shi)工(gong)(gong)(gong)在節(jie)點期內迅速展開。面(mian)對由于地(di)質(zhi)條件(jian)的(de)(de)(de)復(fu)雜造成頂(ding)管(guan)(guan)(guan)井(jing)(jing)的(de)(de)(de)沉(chen)降不均(jun)，項(xiang)目(mu)部(bu)質(zhi)量技術(shu)人員就(jiu)所遇到(dao)的(de)(de)(de)工(gong)(gong)(gong)程問題進行攻關，并根據每(mei)個(ge)頂(ding)管(guan)(guan)(guan)井(jing)(jing)在施(shi)工(gong)(gong)(gong)過(guo)程中所遇到(dao)的(de)(de)(de)不同(tong)土(tu)質(zhi)結構(gou)采(cai)取不同(tong)的(de)(de)(de)施(shi)工(gong)(gong)(gong)方(fang)(fang)法(fa)(fa)。特別(bie)是對2#沉(chen)井(jing)(jing)的(de)(de)(de)糾偏方(fang)(fang)式，項(xiang)目(mu)部(bu)采(cai)用了液(ye)壓頂(ding)及井(jing)(jing)外土(tu)方(fang)(fang)卸載相結合(he)的(de)(de)(de)方(fang)(fang)式來(lai)使沉(chen)降不均(jun)勻(yun)的(de)(de)(de)沉(chen)井(jing)(jing)均(jun)勻(yun)下沉(chen)。
中(zhong)冶寶冶還對已(yi)施(shi)工的(de)各(ge)(ge)個頂(ding)管井進(jin)行(xing)量(liang)進(jin)行(xing)質(zhi)量(liang)評價。經檢查，各(ge)(ge)個頂(ding)管井的(de)施(shi)工質(zhi)量(liang)良好。在深基坑施(shi)工過程中(zhong)采用寶鋼(gang)的(de)標準(zhun)對現場施(shi)工隊伍進(jin)行(xing)了管理，各(ge)(ge)項安全措施(shi)到位。目前，第一節段2號井－1號井頂(ding)管工程11月初開頂(ding)，頂(ding)管管材已(yi)經生(sheng)產100條節。
