11月3日17時(shi)55分，四川成都電(dian)網220千(qian)伏尖長線跨(kua)越(yue)成昆(kun)鐵路(lu)貨車(che)外(wai)繞線府河(he)特大橋改造工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)順利竣工(gong)(gong)(gong)(gong)(gong)并恢復供電(dian)。該工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)不僅有力(li)(li)地支持了成昆(kun)鐵路(lu)貨車(che)外(wai)繞線工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)建設，而且開創了四川電(dian)力(li)(li)鐵路(lu)跨(kua)越(yue)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)史上施工(gong)(gong)(gong)(gong)(gong)難度最大、鋼管塔最高、最重、起用(yong)吊車(che)噸位最大四項紀錄。
在(zai)雙流(liu)縣(xian)公興鎮蘭溝村現(xian)場，正(zheng)在(zai)施工的(de)成昆鐵路貨(huo)車(che)外繞(rao)線(xian)橋墩兩側，已經立起(qi)兩座鋼管(guan)塔(ta)(ta)，其中81.5米高的(de)鋼管(guan)塔(ta)(ta)旁邊還(huan)有(you)一輛伸出90多米長臂的(de)吊車(che)。成都電(dian)(dian)業局(ju)輸(shu)電(dian)(dian)管(guan)理(li)所近百(bai)名員工正(zheng)在(zai)塔(ta)(ta)上緊張作業。
據(ju)工程負責人馬勇介紹，由于成(cheng)(cheng)昆鐵(tie)路貨車(che)外繞線(xian)府(fu)河(he)特大橋(qiao)將從220千伏尖(jian)長線(xian)下(xia)面(mian)穿過，需要(yao)對尖(jian)長線(xian)府(fu)河(he)特大橋(qiao)段進行(xing)升(sheng)高改造(zao)，以保證線(xian)路安(an)全。根(gen)據(ju)工程要(yao)求(qiu)，輸電所(suo)新(xin)建了兩座成(cheng)(cheng)都市目前(qian)最(zui)高的組合式鋼(gang)管鐵(tie)塔。
據了解，成昆(kun)鐵路貨車外(wai)繞線工程系“5?12”汶川(chuan)大(da)地震災后(hou)重(zhong)建重(zhong)點項目(mu)。
