中國建筑工程總公司襄樊漢江三橋項目近日圓滿完成“6483”節點目標（即完成主墩水上樁基64根、陸上樁基480根、產值3億元）。截至目前，項目累計完成主墩64根水上樁基、陸上530根樁基、39座承臺、9個橋墩墩身施工，完成產值3億元。
襄樊漢江三(san)橋(qiao)主(zhu)(zhu)(zhu)橋(qiao)為(wei)(wei)雙塔(ta)(ta)雙半(ban)(ban)索(suo)預應力混凝土(tu)半(ban)(ban)漂(piao)浮體(ti)系斜拉橋(qiao)，南索(suo)塔(ta)(ta)總高(gao)度(du)122.5米(mi)、北索(suo)塔(ta)(ta)總高(gao)度(du)120.3米(mi)。該工(gong)(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)有(you)五大(da)(da)難(nan)(nan)點：一是(shi)主(zhu)(zhu)(zhu)線(xian)橋(qiao)梁跨水面寬(kuan)、水中(zhong)(zhong)墩位(wei)多，水上施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)組織困難(nan)(nan)、措施(shi)費用(yong)高(gao)。二是(shi)水中(zhong)(zhong)基礎施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)難(nan)(nan)度(du)大(da)(da)，其(qi)承(cheng)臺設(she)計面標(biao)高(gao)均位(wei)于(yu)河床以下。三(san)是(shi)地(di)質情況復雜，地(di)層(ceng)中(zhong)(zhong)存在超(chao)厚(hou)的卵(luan)石層(ceng)，且(qie)下部巖層(ceng)中(zhong)(zhong)可能存在溶洞，給(gei)大(da)(da)直徑超(chao)長樁基施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)帶來難(nan)(nan)度(du)。四是(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)體(ti)量(liang)(liang)大(da)(da)，混凝土(tu)總量(liang)(liang)達30萬(wan)立(li)方米(mi)，施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)歷(li)時長、工(gong)(gong)(gong)(gong)(gong)(gong)(gong)期緊。五是(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)程(cheng)涉及多種(zhong)類型(xing)橋(qiao)梁結(jie)構，施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)藝多，其(qi)中(zhong)(zhong)主(zhu)(zhu)(zhu)跨310米(mi)的半(ban)(ban)漂(piao)浮體(ti)系斜拉橋(qiao)技術(shu)(shu)含量(liang)(liang)高(gao)、施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)難(nan)(nan)度(du)大(da)(da)。為(wei)(wei)確保(bao)質量(liang)(liang)和(he)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)期，項(xiang)目始終堅持(chi)以高(gao)起點、高(gao)定(ding)位(wei)、高(gao)標(biao)準組織施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)生產(chan)(chan)，及時組織精良(liang)設(she)備(bei)進場，10臺全液壓(ya)氣舉反循環(huan)鉆機、14臺德(de)國寶峨260旋挖鉆機等頂尖(jian)設(she)備(bei)為(wei)(wei)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)生產(chan)(chan)順利進行(xing)提供了有(you)力保(bao)障。同時，項(xiang)目聘(pin)請了多名行(xing)業(ye)專家作為(wei)(wei)現場駐地(di)指導(dao)，強化了項(xiang)目部技術(shu)(shu)力量(liang)(liang)，并積(ji)極尋求與高(gao)校和(he)兄弟單位(wei)開展(zhan)技術(shu)(shu)交流，確保(bao)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)方案達到最(zui)優。此外，項(xiang)目以黨員先(xian)鋒號(hao)、工(gong)(gong)(gong)(gong)(gong)(gong)(gong)人(ren)先(xian)鋒號(hao)、青年(nian)文明(ming)號(hao)“三(san)號(hao)聯(lian)創”為(wei)(wei)抓手(shou)，大(da)(da)力開展(zhan)勞(lao)動競賽。下半(ban)(ban)年(nian)，項(xiang)目將全力投入到主(zhu)(zhu)(zhu)塔(ta)(ta)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)之中(zhong)(zhong)，預計今年(nian)12月31日前(qian)完(wan)成主(zhu)(zhu)(zhu)橋(qiao)100個(ge)承(cheng)臺、80根墩柱(zhu)、2個(ge)主(zhu)(zhu)(zhu)塔(ta)(ta)下塔(ta)(ta)柱(zhu)施(shi)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)，完(wan)成產(chan)(chan)值2.8億元(yuan)。
