近日(ri)，中(zhong)鐵(tie)九局(ju)施(shi)工(gong)(gong)的(de)福廈鐵(tie)路控制工(gong)(gong)期(qi)工(gong)(gong)程黃(huang)(huang)石特(te)(te)大(da)橋實現(xian)全(quan)橋架(jia)(jia)通(tong)(tong)。黃(huang)(huang)石特(te)(te)大(da)橋全(quan)長2819.2米，橋墩臺89個，需架(jia)(jia)設(she)(she)箱梁(liang)85孔。是(shi)全(quan)線控制工(gong)(gong)期(qi)工(gong)(gong)程之一，為全(quan)標段“卡(ka)脖子工(gong)(gong)程”。黃(huang)(huang)石特(te)(te)大(da)橋地(di)(di)(di)形復(fu)雜，位(wei)于沿海地(di)(di)(di)區軟土路基段。地(di)(di)(di)質(zhi)(zhi)差(cha)異較大(da)，有流沙、孤石、斜巖等(deng)不(bu)良地(di)(di)(di)質(zhi)(zhi)條(tiao)件。與地(di)(di)(di)方道路交叉多，橫跨交通(tong)(tong)密集(ji)的(de)202省道及河流，施(shi)工(gong)(gong)難(nan)度大(da)。橋梁(liang)鉆(zhan)、挖孔樁721根(gen)，其中(zhong)最(zui)(zui)長61.5米，最(zui)(zui)短(duan)8米。為滿足設(she)(she)計要求，中(zhong)鐵(tie)九局(ju)項目部加大(da)投(tou)入，加設(she)(she)多臺沖擊鉆(zhan)機，克服地(di)(di)(di)質(zhi)(zhi)等(deng)不(bu)良因素影響。加強(qiang)與地(di)(di)(di)方溝通(tong)(tong)，協調交叉難(nan)題，加快了施(shi)工(gong)(gong)進程，創造單(dan)日(ri)架(jia)(jia)4孔32米900噸箱梁(liang)新紀(ji)錄，900噸架(jia)(jia)橋機成(cheng)功完(wan)成(cheng)4次(ci)變(bian)跨1次(ci)轉場(chang)，順利實現(xian)了全(quan)橋貫通(tong)(tong)。
