項目(mu)總監趙瑞明(ming)介紹，該項目(mu)建設主要(yao)(yao)(yao)有著四(si)個(ge)方面的(de)(de)特(te)點和挑戰(zhan)，第(di)一，不利氣(qi)(qi)候條件。大(da)橋(qiao)地處烏蒙山區，四(si)季(ji)(ji)氣(qi)(qi)溫變化差異較大(da)，每年5～10月為雨季(ji)(ji)，加(jia)之(zhi)該地區雨雪霧、大(da)風(feng)等(deng)惡劣天氣(qi)(qi)較多，嚴重影響并(bing)(bing)對施(shi)(shi)工(gong)(gong)測量、鋼桁(heng)梁(liang)(liang)吊裝等(deng)施(shi)(shi)工(gong)(gong)作業及生產效率的(de)(de)提高(gao)(gao)都有很(hen)(hen)大(da)的(de)(de)影響，施(shi)(shi)工(gong)(gong)風(feng)險控(kong)(kong)(kong)(kong)制要(yao)(yao)(yao)求(qiu)高(gao)(gao)。第(di)二，施(shi)(shi)工(gong)(gong)場地受限。橋(qiao)址(zhi)處于(yu)峽谷中(zhong)，場地極(ji)(ji)為狹(xia)窄(zhai)，給鋼桁(heng)梁(liang)(liang)拼(pin)(pin)裝及運輸(shu)等(deng)施(shi)(shi)工(gong)(gong)組織(zhi)協調帶(dai)來極(ji)(ji)大(da)挑戰(zhan)，鋼桁(heng)梁(liang)(liang)采用纜索吊吊裝，起吊噸(dun)位達(da)350噸(dun)以上，在(zai)國內鋼桁(heng)梁(liang)(liang)施(shi)(shi)工(gong)(gong)中(zhong)屬于(yu)首例。第(di)三，施(shi)(shi)工(gong)(gong)精(jing)度(du)(du)要(yao)(yao)(yao)求(qiu)高(gao)(gao)。鋼桁(heng)梁(liang)(liang)采用大(da)節段、長懸(xuan)臂(bei)拼(pin)(pin)裝，最(zui)大(da)拼(pin)(pin)裝長度(du)(du)400米(mi)，線(xian)型(xing)控(kong)(kong)(kong)(kong)制尤為關(guan)鍵，長懸(xuan)臂(bei)拼(pin)(pin)裝狀態軸(zhou)線(xian)與標(biao)高(gao)(gao)的(de)(de)精(jing)度(du)(du)控(kong)(kong)(kong)(kong)制和調整都十分困難，軸(zhou)線(xian)偏差精(jing)度(du)(du)標(biao)高(gao)(gao)控(kong)(kong)(kong)(kong)制在(zai)10毫(hao)米(mi)以內，對施(shi)(shi)工(gong)(gong)質量控(kong)(kong)(kong)(kong)制要(yao)(yao)(yao)求(qiu)很(hen)(hen)高(gao)(gao)。第(di)四(si)、施(shi)(shi)工(gong)(gong)安(an)(an)(an)全(quan)(quan)(quan)(quan)風(feng)險大(da)。基于(yu)本工(gong)(gong)程施(shi)(shi)工(gong)(gong)特(te)點，我們(men)十分重視安(an)(an)(an)全(quan)(quan)(quan)(quan)生產管(guan)控(kong)(kong)(kong)(kong)與監理工(gong)(gong)作，并(bing)(bing)積極(ji)(ji)組織(zhi)召開有關(guan)加(jia)強質量、安(an)(an)(an)全(quan)(quan)(quan)(quan)技術(shu)交(jiao)底(di)和培(pei)訓教育的(de)(de)會議，使(shi)全(quan)(quan)(quan)(quan)體(ti)人(ren)員安(an)(an)(an)全(quan)(quan)(quan)(quan)思想從(cong)“要(yao)(yao)(yao)我安(an)(an)(an)全(quan)(quan)(quan)(quan)”自覺的(de)(de)轉變成“我要(yao)(yao)(yao)安(an)(an)(an)全(quan)(quan)(quan)(quan)”，養(yang)成變被動為主動的(de)(de)安(an)(an)(an)全(quan)(quan)(quan)(quan)質量意(yi)識。多種管(guan)理方式(shi)相結合，每個(ge)人(ren)都應及時的(de)(de)發現并(bing)(bing)排查(cha)自身周邊(bian)的(de)(de)安(an)(an)(an)全(quan)(quan)(quan)(quan)隱患，并(bing)(bing)予(yu)以排除，從(cong)而使(shi)整個(ge)工(gong)(gong)程項目(mu)的(de)(de)安(an)(an)(an)全(quan)(quan)(quan)(quan)生產和工(gong)(gong)程質量得以保持(chi)在(zai)一個(ge)可控(kong)(kong)(kong)(kong)的(de)(de)狀態。
為(wei)解決技(ji)術(shu)難(nan)題、保(bao)證(zheng)鴨池河大(da)橋建成優質(zhi)工程，大(da)橋建設(she)(she)者(zhe)們以“中國建設(she)(she)工程魯班獎”為(wei)目標，積極(ji)開(kai)展科技(ji)攻關，在“索塔(ta)節(jie)段鋼筋整(zheng)體(ti)吊(diao)裝施工技(ji)術(shu)”、“冬季高塔(ta)蒸養成套技(ji)術(shu)”、“350噸大(da)跨徑纜(lan)索吊(diao)工程應用技(ji)術(shu)”、“鋼桁梁(liang)組裝與整(zheng)體(ti)吊(diao)裝聯(lian)合施工技(ji)術(shu)”、“連體(ti)掛籃懸臂與落地大(da)鋼管支架施工工藝(yi)”五個方面取得重大(da)突破，實現(xian)了重大(da)創(chuang)新，保(bao)證(zheng)了大(da)橋建設(she)(she)順利(li)推進。
