項(xiang)(xiang)目總監(jian)趙瑞明介紹，該項(xiang)(xiang)目建設主(zhu)(zhu)要(yao)(yao)有著四個方面(mian)的(de)(de)(de)特點和(he)挑戰(zhan)，第(di)(di)一，不利氣候條件。大(da)橋地處(chu)烏蒙山(shan)區，四季(ji)氣溫變化差異較大(da)，每(mei)年(nian)5～10月為(wei)雨季(ji)，加(jia)之該地區雨雪霧、大(da)風(feng)(feng)等惡(e)劣天氣較多(duo)，嚴重影(ying)響并對施(shi)(shi)(shi)(shi)工(gong)測(ce)量(liang)、鋼(gang)(gang)桁(heng)梁吊(diao)裝(zhuang)(zhuang)(zhuang)等施(shi)(shi)(shi)(shi)工(gong)作(zuo)業(ye)及生(sheng)產(chan)效率的(de)(de)(de)提高(gao)都(dou)有很大(da)的(de)(de)(de)影(ying)響，施(shi)(shi)(shi)(shi)工(gong)風(feng)(feng)險控(kong)(kong)制要(yao)(yao)求高(gao)。第(di)(di)二(er)，施(shi)(shi)(shi)(shi)工(gong)場地受限。橋址處(chu)于(yu)(yu)峽谷中，場地極為(wei)狹窄，給鋼(gang)(gang)桁(heng)梁拼(pin)裝(zhuang)(zhuang)(zhuang)及運輸等施(shi)(shi)(shi)(shi)工(gong)組織協(xie)調帶(dai)來極大(da)挑戰(zhan)，鋼(gang)(gang)桁(heng)梁采用(yong)纜索吊(diao)吊(diao)裝(zhuang)(zhuang)(zhuang)，起(qi)吊(diao)噸位達350噸以(yi)(yi)上，在(zai)(zai)國(guo)內鋼(gang)(gang)桁(heng)梁施(shi)(shi)(shi)(shi)工(gong)中屬于(yu)(yu)首例。第(di)(di)三(san)，施(shi)(shi)(shi)(shi)工(gong)精度(du)要(yao)(yao)求高(gao)。鋼(gang)(gang)桁(heng)梁采用(yong)大(da)節段(duan)、長懸(xuan)(xuan)臂(bei)拼(pin)裝(zhuang)(zhuang)(zhuang)，最大(da)拼(pin)裝(zhuang)(zhuang)(zhuang)長度(du)400米，線(xian)型控(kong)(kong)制尤為(wei)關鍵(jian)，長懸(xuan)(xuan)臂(bei)拼(pin)裝(zhuang)(zhuang)(zhuang)狀(zhuang)態軸(zhou)線(xian)與標高(gao)的(de)(de)(de)精度(du)控(kong)(kong)制和(he)調整(zheng)都(dou)十分(fen)(fen)困難，軸(zhou)線(xian)偏差精度(du)標高(gao)控(kong)(kong)制在(zai)(zai)10毫米以(yi)(yi)內，對施(shi)(shi)(shi)(shi)工(gong)質(zhi)量(liang)控(kong)(kong)制要(yao)(yao)求很高(gao)。第(di)(di)四、施(shi)(shi)(shi)(shi)工(gong)安(an)全(quan)(quan)風(feng)(feng)險大(da)。基(ji)于(yu)(yu)本(ben)工(gong)程施(shi)(shi)(shi)(shi)工(gong)特點，我(wo)(wo)們(men)十分(fen)(fen)重視安(an)全(quan)(quan)生(sheng)產(chan)管控(kong)(kong)與監(jian)理工(gong)作(zuo)，并積極組織召開有關加(jia)強質(zhi)量(liang)、安(an)全(quan)(quan)技術交底(di)和(he)培訓教育的(de)(de)(de)會議，使全(quan)(quan)體人員安(an)全(quan)(quan)思想從(cong)“要(yao)(yao)我(wo)(wo)安(an)全(quan)(quan)”自覺的(de)(de)(de)轉變成(cheng)“我(wo)(wo)要(yao)(yao)安(an)全(quan)(quan)”，養成(cheng)變被動(dong)為(wei)主(zhu)(zhu)動(dong)的(de)(de)(de)安(an)全(quan)(quan)質(zhi)量(liang)意識。多(duo)種(zhong)管理方式相結合，每(mei)個人都(dou)應及時(shi)的(de)(de)(de)發現并排查自身周邊的(de)(de)(de)安(an)全(quan)(quan)隱患，并予以(yi)(yi)排除，從(cong)而(er)使整(zheng)個工(gong)程項(xiang)(xiang)目的(de)(de)(de)安(an)全(quan)(quan)生(sheng)產(chan)和(he)工(gong)程質(zhi)量(liang)得以(yi)(yi)保持在(zai)(zai)一個可控(kong)(kong)的(de)(de)(de)狀(zhuang)態。
為(wei)解決(jue)技(ji)術(shu)難題、保證鴨池河大(da)橋(qiao)建(jian)成(cheng)優質工程(cheng)，大(da)橋(qiao)建(jian)設者們以“中國建(jian)設工程(cheng)魯班獎”為(wei)目標，積極開展科技(ji)攻關，在“索(suo)(suo)塔節(jie)段鋼(gang)筋整體吊(diao)(diao)裝(zhuang)施(shi)工技(ji)術(shu)”、“冬季高塔蒸養成(cheng)套(tao)技(ji)術(shu)”、“350噸(dun)大(da)跨徑纜(lan)索(suo)(suo)吊(diao)(diao)工程(cheng)應用技(ji)術(shu)”、“鋼(gang)桁梁組裝(zhuang)與整體吊(diao)(diao)裝(zhuang)聯合施(shi)工技(ji)術(shu)”、“連體掛籃懸臂(bei)與落(luo)地大(da)鋼(gang)管(guan)支架施(shi)工工藝(yi)”五個(ge)方面取(qu)得重(zhong)大(da)突(tu)破，實(shi)現了重(zhong)大(da)創新，保證了大(da)橋(qiao)建(jian)設順利推進。
