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)樊漢江三橋(qiao)主(zhu)橋(qiao)為(wei)雙(shuang)塔(ta)雙(shuang)半索(suo)(suo)(suo)預(yu)應力(li)混(hun)凝土半漂浮(fu)(fu)體系斜拉橋(qiao)，南索(suo)(suo)(suo)塔(ta)總(zong)高度(du)(du)122.5米(mi)、北索(suo)(suo)(suo)塔(ta)總(zong)高度(du)(du)120.3米(mi)。該工(gong)(gong)(gong)(gong)(gong)程(cheng)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)有五大(da)難(nan)(nan)點：一是主(zhu)線橋(qiao)梁(liang)跨水(shui)(shui)面(mian)寬、水(shui)(shui)中墩(dun)(dun)位(wei)多(duo)，水(shui)(shui)上施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)組織困難(nan)(nan)、措施(shi)(shi)(shi)(shi)費用(yong)高。二是水(shui)(shui)中基礎(chu)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)難(nan)(nan)度(du)(du)大(da)，其(qi)承臺設(she)計面(mian)標(biao)高均位(wei)于河床以(yi)下(xia)(xia)。三是地(di)質情況復雜(za)，地(di)層中存在超厚的卵石層，且(qie)下(xia)(xia)部巖層中可(ke)能存在溶洞，給大(da)直徑超長(chang)樁基施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)帶來難(nan)(nan)度(du)(du)。四是工(gong)(gong)(gong)(gong)(gong)程(cheng)體量(liang)大(da)，混(hun)凝土總(zong)量(liang)達30萬(wan)立方(fang)米(mi)，施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)歷時長(chang)、工(gong)(gong)(gong)(gong)(gong)期(qi)緊。五是工(gong)(gong)(gong)(gong)(gong)程(cheng)涉(she)及多(duo)種類(lei)型橋(qiao)梁(liang)結構(gou)，施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝多(duo)，其(qi)中主(zhu)跨310米(mi)的半漂浮(fu)(fu)體系斜拉橋(qiao)技術含量(liang)高、施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)難(nan)(nan)度(du)(du)大(da)。為(wei)確保(bao)(bao)質量(liang)和工(gong)(gong)(gong)(gong)(gong)期(qi)，項(xiang)目(mu)始終(zhong)堅持以(yi)高起(qi)點、高定位(wei)、高標(biao)準組織施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)生(sheng)(sheng)產(chan)，及時組織精良設(she)備進(jin)(jin)場，10臺全液壓氣舉(ju)反循環鉆(zhan)機、14臺德國寶峨260旋(xuan)挖鉆(zhan)機等(deng)頂(ding)尖設(she)備為(wei)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)生(sheng)(sheng)產(chan)順利進(jin)(jin)行(xing)提供了有力(li)保(bao)(bao)障。同時，項(xiang)目(mu)聘請了多(duo)名行(xing)業專(zhuan)家作為(wei)現場駐地(di)指導，強(qiang)化了項(xiang)目(mu)部技術力(li)量(liang)，并積(ji)極尋(xun)求與高校(xiao)和兄弟(di)單位(wei)開展技術交流，確保(bao)(bao)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)方(fang)案達到最優(you)。此(ci)外，項(xiang)目(mu)以(yi)黨員(yuan)先(xian)鋒號(hao)、工(gong)(gong)(gong)(gong)(gong)人先(xian)鋒號(hao)、青年文明號(hao)“三號(hao)聯創”為(wei)抓手，大(da)力(li)開展勞(lao)動競(jing)賽。下(xia)(xia)半年，項(xiang)目(mu)將全力(li)投入(ru)到主(zhu)塔(ta)施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)之中，預(yu)計今(jin)年12月31日前(qian)完成主(zhu)橋(qiao)100個承臺、80根墩(dun)(dun)柱、2個主(zhu)塔(ta)下(xia)(xia)塔(ta)柱施(shi)(shi)(shi)(shi)工(gong)(gong)(gong)(gong)(gong)，完成產(chan)值2.8億元。
