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(xiang)樊漢江(jiang)三(san)橋(qiao)主(zhu)(zhu)橋(qiao)為雙塔(ta)(ta)雙半索預應力(li)混凝土半漂(piao)浮體(ti)系斜拉(la)橋(qiao)，南(nan)索塔(ta)(ta)總高(gao)度(du)122.5米(mi)、北索塔(ta)(ta)總高(gao)度(du)120.3米(mi)。該(gai)工(gong)(gong)(gong)程施(shi)(shi)(shi)工(gong)(gong)(gong)有(you)五大(da)(da)難(nan)點：一是主(zhu)(zhu)線橋(qiao)梁(liang)(liang)跨水面(mian)寬、水中(zhong)墩位多(duo)，水上施(shi)(shi)(shi)工(gong)(gong)(gong)組(zu)織(zhi)(zhi)(zhi)困(kun)難(nan)、措施(shi)(shi)(shi)費用高(gao)。二是水中(zhong)基礎施(shi)(shi)(shi)工(gong)(gong)(gong)難(nan)度(du)大(da)(da)，其承(cheng)臺(tai)設計面(mian)標高(gao)均位于河床以(yi)下(xia)。三(san)是地質情況復雜(za)，地層中(zhong)存(cun)在(zai)超厚的(de)卵石(shi)層，且下(xia)部(bu)(bu)巖層中(zhong)可能(neng)存(cun)在(zai)溶洞(dong)，給大(da)(da)直徑超長樁(zhuang)基施(shi)(shi)(shi)工(gong)(gong)(gong)帶來難(nan)度(du)。四是工(gong)(gong)(gong)程體(ti)量大(da)(da)，混凝土總量達30萬立(li)方米(mi)，施(shi)(shi)(shi)工(gong)(gong)(gong)歷時長、工(gong)(gong)(gong)期緊。五是工(gong)(gong)(gong)程涉(she)及(ji)多(duo)種類型橋(qiao)梁(liang)(liang)結構，施(shi)(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝多(duo)，其中(zhong)主(zhu)(zhu)跨310米(mi)的(de)半漂(piao)浮體(ti)系斜拉(la)橋(qiao)技術(shu)含量高(gao)、施(shi)(shi)(shi)工(gong)(gong)(gong)難(nan)度(du)大(da)(da)。為確(que)保質量和(he)工(gong)(gong)(gong)期，項(xiang)目始終堅持以(yi)高(gao)起點、高(gao)定(ding)位、高(gao)標準組(zu)織(zhi)(zhi)(zhi)施(shi)(shi)(shi)工(gong)(gong)(gong)生產，及(ji)時組(zu)織(zhi)(zhi)(zhi)精良設備(bei)進場(chang)，10臺(tai)全液壓氣舉(ju)反循環鉆(zhan)機、14臺(tai)德國寶峨260旋(xuan)挖(wa)鉆(zhan)機等頂尖設備(bei)為施(shi)(shi)(shi)工(gong)(gong)(gong)生產順利進行(xing)提供了(le)有(you)力(li)保障(zhang)。同時，項(xiang)目聘請了(le)多(duo)名行(xing)業專家(jia)作為現(xian)場(chang)駐地指(zhi)導，強化了(le)項(xiang)目部(bu)(bu)技術(shu)力(li)量，并積極尋求與(yu)高(gao)校和(he)兄弟單位開(kai)展技術(shu)交流，確(que)保施(shi)(shi)(shi)工(gong)(gong)(gong)方案達到最優。此外(wai)，項(xiang)目以(yi)黨員先鋒(feng)號(hao)、工(gong)(gong)(gong)人(ren)先鋒(feng)號(hao)、青年文明(ming)號(hao)“三(san)號(hao)聯創”為抓手(shou)，大(da)(da)力(li)開(kai)展勞動競賽。下(xia)半年，項(xiang)目將全力(li)投入到主(zhu)(zhu)塔(ta)(ta)施(shi)(shi)(shi)工(gong)(gong)(gong)之中(zhong)，預計今年12月31日前完成主(zhu)(zhu)橋(qiao)100個承(cheng)臺(tai)、80根墩柱、2個主(zhu)(zhu)塔(ta)(ta)下(xia)塔(ta)(ta)柱施(shi)(shi)(shi)工(gong)(gong)(gong)，完成產值(zhi)2.8億元。
