5月28日，青島(dao)(dao)地鐵(tie)1號(hao)(hao)線(xian)勝利(li)橋站開閉所及其外電(dian)(dian)源順利(li)完(wan)成送電(dian)(dian)，為青島(dao)(dao)地鐵(tie)1號(hao)(hao)線(xian)后(hou)續“電(dian)(dian)通”提供前提條件。

工人(ren)進行開關合閘送電(dian)操作

地鐵開閉(bi)(bi)所是電源接入地鐵的“樞(shu)紐站”，可以把它理解成為地鐵運(yun)行(xing)提供(gong)能量(liang)的“心臟(zang)”。勝利橋(qiao)站開閉(bi)(bi)所承(cheng)擔(dan)著1號(hao)線7站8區間總共約11公(gong)里的供(gong)電任務(wu)。青島市地鐵一號(hao)線有(you)限公(gong)司本著“精(jing)細管理，爭創(chuang)一流”理念主動協調，克服了(le)前期(qi)(qi)設(she)備進場難度大、施工工期(qi)(qi)緊等諸(zhu)多不利因素(su)，通過科學合理的施工組織(zhi)，有(you)效避(bi)免(mian)了(le)交叉施工。

外電(dian)源為公用變電(dian)站與地鐵(tie)開閉(bi)所的連接線(xian)(xian)(xian)路，是(shi)地鐵(tie)運行的“動力血管”，為地鐵(tie)的動力保駕(jia)護航(hang)。勝利橋開閉(bi)所的兩路外電(dian)源分別為水勝線(xian)(xian)(xian)、虎勝線(xian)(xian)(xian)，全線(xian)(xian)(xian)為單回35千伏高壓電(dian)纜(lan)線(xian)(xian)(xian)路。

由于工(gong)程全線位于老城(cheng)區，在實(shi)際施(shi)工(gong)過程中面(mian)臨(lin)重重困難(nan)：一是(shi)交叉作(zuo)業多(duo)、交通(tong)干擾大，基本在夜間(jian)施(shi)工(gong)，白天需恢復道(dao)(dao)路(lu)通(tong)車，特別是(shi)四流南路(lu)的(de)拖拉管(guan)施(shi)工(gong)需要穿越車道(dao)(dao)，地(di)下(xia)管(guan)線錯綜復雜且地(di)質不良等因素造成施(shi)工(gong)難(nan)度大；二是(shi)施(shi)工(gong)條件受到(dao)局限，作(zuo)業空間(jian)小，管(guan)廊內(nei)每(mei)段電纜(lan)長(chang)度平均為(wei)420米、重達6噸(dun)，且只能靠(kao)人(ren)力將(jiang)電纜(lan)抬放到(dao)2米高的(de)支架上；三是(shi)利用已建的(de)老舊管(guan)道(dao)(dao)轉彎(wan)多(duo)且半徑小，部(bu)分(fen)電纜(lan)井深度達2.5米，積水(shui)多(duo)、管(guan)道(dao)(dao)淤堵，敷(fu)設電纜(lan)時需要不間(jian)斷進行排水(shui)作(zuo)業。

為保證(zheng)兩條外電(dian)源線(xian)(xian)路如(ru)期送電(dian)，一號線(xian)(xian)公司及施(shi)工(gong)(gong)(gong)(gong)單(dan)位一方(fang)面(mian)提前謀劃統籌(chou)安排、嚴格管(guan)理(li)責任到人，每日工(gong)(gong)(gong)(gong)程(cheng)進度一匯報，保證(zheng)了安全、質(zhi)量(liang)(liang)和進度均(jun)衡有序推進工(gong)(gong)(gong)(gong)程(cheng)；另(ling)一方(fang)面(mian)精心組織施(shi)工(gong)(gong)(gong)(gong)單(dan)位投入(ru)更多(duo)的人力(li)(li)(li)、物力(li)(li)(li)、精力(li)(li)(li)保證(zheng)安全、質(zhi)量(liang)(liang)和進度，采(cai)取突擊式夜間加班、節假(jia)日不(bu)間斷施(shi)工(gong)(gong)(gong)(gong)、配備多(duo)套(tao)施(shi)工(gong)(gong)(gong)(gong)班組等多(duo)措并舉。在(zai)青島市各相關部門、供電(dian)公司的大力(li)(li)(li)支持與幫助下，工(gong)(gong)(gong)(gong)程(cheng)僅用4個月(yue)的時間，保質(zhi)保量(liang)(liang)如(ru)期送電(dian)。

此外(wai)(wai)勝利橋開閉(bi)所(suo)外(wai)(wai)電(dian)(dian)源(yuan)工(gong)(gong)程還(huan)肩負著(zhu)3號(hao)線振華路站開閉(bi)所(suo)外(wai)(wai)電(dian)(dian)源(yuan)水振線改(gai)造任務和(he)8號(hao)線閻(yan)家山(shan)開閉(bi)所(suo)外(wai)(wai)電(dian)(dian)源(yuan)預留工(gong)(gong)作(zuo)。水振線是青島地鐵第一(yi)條對已運(yun)營(ying)線路進行外(wai)(wai)電(dian)(dian)源(yuan)改(gai)造的線路。

勝利橋開閉所(suo)成功送(song)電作(zuo)為青島地(di)鐵1號(hao)線(xian)供電系統里程碑(bei)節點，拉(la)開了(le)1號(hao)線(xian)南(nan)(nan)段電通(tong)的(de)序幕，宣告(gao)著青島1號(hao)線(xian)南(nan)(nan)段送(song)電工(gong)作(zuo)啟動，為后續(xu)中段各車站電通(tong)邁出(chu)了(le)堅實(shi)的(de)一步，1號(hao)線(xian)各車站、區間設備聯調(diao)聯試工(gong)作(zuo)不再受任何外部環境影響。
