5月28日，青(qing)島(dao)地(di)鐵1號線(xian)(xian)勝利(li)(li)橋站開閉所及(ji)其外電源順利(li)(li)完成(cheng)送電，為青(qing)島(dao)地(di)鐵1號線(xian)(xian)后續(xu)“電通”提供前提條件。

工人進行開關合閘送電操作

地(di)鐵(tie)開閉(bi)(bi)所(suo)是(shi)電源接入地(di)鐵(tie)的“樞紐站(zhan)”，可以把它理(li)解(jie)成為(wei)地(di)鐵(tie)運行提供(gong)能(neng)量的“心臟”。勝利橋(qiao)站(zhan)開閉(bi)(bi)所(suo)承(cheng)擔著1號線7站(zhan)8區(qu)間總共約11公(gong)(gong)里的供(gong)電任務。青島市地(di)鐵(tie)一(yi)號線有(you)限(xian)公(gong)(gong)司(si)本著“精(jing)細管理(li)，爭創一(yi)流”理(li)念主動協調，克服了(le)前期(qi)設備進(jin)場(chang)難(nan)度(du)大、施(shi)工(gong)工(gong)期(qi)緊等諸多不(bu)利因素，通過科學合理(li)的施(shi)工(gong)組(zu)織(zhi)，有(you)效避免了(le)交叉施(shi)工(gong)。

外(wai)電(dian)源為(wei)公用變電(dian)站與(yu)地(di)鐵開(kai)閉所的(de)連接(jie)線路(lu)，是地(di)鐵運行(xing)的(de)“動力(li)血管”，為(wei)地(di)鐵的(de)動力(li)保駕護航。勝(sheng)(sheng)利橋(qiao)開(kai)閉所的(de)兩路(lu)外(wai)電(dian)源分(fen)別為(wei)水勝(sheng)(sheng)線、虎勝(sheng)(sheng)線，全線為(wei)單回35千(qian)伏高壓電(dian)纜(lan)線路(lu)。

由于工(gong)(gong)(gong)程全線位(wei)于老城(cheng)區，在實(shi)際施(shi)工(gong)(gong)(gong)過(guo)程中面臨重重困難(nan)：一是交(jiao)叉作業(ye)(ye)多、交(jiao)通干(gan)擾大(da)，基本在夜(ye)間施(shi)工(gong)(gong)(gong)，白天需(xu)恢復道(dao)路通車，特別(bie)是四流南路的拖(tuo)拉管(guan)(guan)施(shi)工(gong)(gong)(gong)需(xu)要穿越車道(dao)，地(di)下管(guan)(guan)線錯綜復雜且地(di)質不良等因素造成施(shi)工(gong)(gong)(gong)難(nan)度大(da)；二(er)是施(shi)工(gong)(gong)(gong)條件受到局限，作業(ye)(ye)空間小，管(guan)(guan)廊內每段電(dian)(dian)纜(lan)長度平均(jun)為420米、重達(da)6噸，且只(zhi)能靠(kao)人力將電(dian)(dian)纜(lan)抬放到2米高的支架(jia)上；三是利用(yong)已建(jian)的老舊管(guan)(guan)道(dao)轉彎多且半(ban)徑(jing)小，部(bu)分電(dian)(dian)纜(lan)井(jing)深度達(da)2.5米，積水多、管(guan)(guan)道(dao)淤(yu)堵，敷設(she)電(dian)(dian)纜(lan)時需(xu)要不間斷進行排水作業(ye)(ye)。

為保(bao)證兩條外電(dian)源線路如期送電(dian)，一號線公司及施(shi)工(gong)(gong)單(dan)位(wei)一方面提前謀劃統籌安(an)(an)排、嚴格管理責(ze)任到人(ren)，每(mei)日工(gong)(gong)程進(jin)(jin)度(du)(du)一匯(hui)報(bao)，保(bao)證了安(an)(an)全、質(zhi)量和(he)進(jin)(jin)度(du)(du)均(jun)衡有序推進(jin)(jin)工(gong)(gong)程；另(ling)一方面精心組織(zhi)施(shi)工(gong)(gong)單(dan)位(wei)投入更多的人(ren)力(li)、物力(li)、精力(li)保(bao)證安(an)(an)全、質(zhi)量和(he)進(jin)(jin)度(du)(du)，采取突擊(ji)式(shi)夜間加班、節假日不(bu)間斷施(shi)工(gong)(gong)、配(pei)備多套施(shi)工(gong)(gong)班組等多措并舉(ju)。在青島市各相關部門、供電(dian)公司的大(da)力(li)支(zhi)持(chi)與幫助下(xia)，工(gong)(gong)程僅用4個月的時間，保(bao)質(zhi)保(bao)量如期送電(dian)。

此外(wai)勝利橋開閉(bi)(bi)所(suo)外(wai)電(dian)源工程還肩負(fu)著3號線(xian)(xian)振(zhen)華路站(zhan)開閉(bi)(bi)所(suo)外(wai)電(dian)源水振(zhen)線(xian)(xian)改造(zao)(zao)任務和8號線(xian)(xian)閻家山開閉(bi)(bi)所(suo)外(wai)電(dian)源預留工作。水振(zhen)線(xian)(xian)是青島地鐵(tie)第(di)一條對(dui)已運營線(xian)(xian)路進(jin)行(xing)外(wai)電(dian)源改造(zao)(zao)的(de)線(xian)(xian)路。

勝利橋開閉(bi)所成功送(song)電(dian)作(zuo)為(wei)青島(dao)地(di)鐵(tie)1號線供電(dian)系統里程(cheng)碑節點，拉開了(le)1號線南段電(dian)通的序幕(mu)，宣告著青島(dao)1號線南段送(song)電(dian)工作(zuo)啟動，為(wei)后續中段各車站電(dian)通邁(mai)出了(le)堅實的一步，1號線各車站、區(qu)間(jian)設備聯調聯試(shi)工作(zuo)不再受任何外部環境影響(xiang)。
