地鐵8號線“雙接頭”分線箱順利送電為1號線勝利橋站開閉所供電保駕護航

5月28日,青島地鐵8號線“雙接頭”分線箱順利完成送電,為地鐵1號線供電提供保障,也為8號線電流接入創造了條件。

地鐵8號(hao)線(xian)(xian)“雙(shuang)接(jie)頭”分(fen)線(xian)(xian)箱是(shi)1號(hao)線(xian)(xian)勝利橋站(zhan)(zhan)(zhan)(zhan)(zhan)開(kai)閉所(suo)(suo)、8號(hao)線(xian)(xian)閆(yan)家(jia)山(shan)(shan)站(zhan)(zhan)(zhan)(zhan)(zhan)開(kai)閉所(suo)(suo)供(gong)電(dian)(dian)共接(jie)工(gong)程(cheng)(cheng),由浩越(青島(dao))建設電(dian)(dian)力工(gong)程(cheng)(cheng)有限(xian)公(gong)司具體實施(shi),該工(gong)程(cheng)(cheng)屬于35千伏高(gao)壓施(shi)工(gong)項目,從國家(jia)電(dian)(dian)網虎(hu)山(shan)(shan)變電(dian)(dian)站(zhan)(zhan)(zhan)(zhan)(zhan)引出一路(lu)高(gao)壓電(dian)(dian)源(yuan)到(dao)分(fen)線(xian)(xian)箱,從分(fen)線(xian)(xian)箱輸(shu)出兩路(lu)電(dian)(dian)源(yuan)。一路(lu)為(wei)地鐵1號(hao)線(xian)(xian)勝利橋站(zhan)(zhan)(zhan)(zhan)(zhan)開(kai)閉所(suo)(suo)及周邊7站(zhan)(zhan)(zhan)(zhan)(zhan)8區間(jian)約11公(gong)里的范圍供(gong)電(dian)(dian);一路(lu)為(wei)地鐵8號(hao)線(xian)(xian)閆(yan)家(jia)山(shan)(shan)站(zhan)(zhan)(zhan)(zhan)(zhan)開(kai)閉所(suo)(suo)南昌路(lu)北站(zhan)(zhan)(zhan)(zhan)(zhan)至(zhi)紅島(dao)科技館站(zhan)(zhan)(zhan)(zhan)(zhan)6站(zhan)(zhan)(zhan)(zhan)(zhan)5區間(jian)約17公(gong)里的范圍供(gong)電(dian)(dian)。主(zhu)要工(gong)作為(wei)新(xin)建分(fen)線(xian)(xian)箱1座、敷設高(gao)壓電(dian)(dian)纜(lan)約420米和電(dian)(dian)纜(lan)設備的試驗調試,以及外(wai)部(bu)相應(ying)的配套工(gong)作。

本(ben)工(gong)程(cheng)采用(yong)(yong)的(de)(de)(de)電(dian)(dian)纜(lan)為目(mu)前青島地(di)鐵最高(gao)規格的(de)(de)(de)單芯高(gao)電(dian)(dian)壓(ya)電(dian)(dian)纜(lan),其直(zhi)徑(jing)達到(dao)7厘米,總重量達6.5噸,需(xu)要將(jiang)3根單芯電(dian)(dian)纜(lan)擺成“品”字形敷(fu)設至(zhi)2米高(gao)的(de)(de)(de)管廊(lang)支(zhi)架(jia)上(shang)固定,受管廊(lang)空間限(xian)制(zhi)(高(gao)2.2米,寬2米)無(wu)法使用(yong)(yong)機械,只能靠有限(xian)的(de)(de)(de)人力將(jiang)沉重的(de)(de)(de)電(dian)(dian)纜(lan)抬放到(dao)支(zhi)架(jia)上(shang),且管廊(lang)支(zhi)架(jia)上(shang)還(huan)有已經通電(dian)(dian)的(de)(de)(de)多條(tiao)高(gao)壓(ya)電(dian)(dian)纜(lan),施工(gong)危(wei)險系數(shu)高(gao),難度大。

“起跑即沖刺、開局(ju)即決戰”八(ba)號線公司(si)迎(ying)難而上(shang)絕不退縮,為滿足1號線勝利橋(qiao)開站閉(bi)所5月(yue)底外部(bu)電源引(yin)入的(de)(de)工(gong)(gong)期需求,從3月(yue)份開始著手準備(bei),僅在短短3個月(yue)時間內(nei)就完(wan)(wan)成(cheng)了方案研(yan)究、圖紙設(she)計、規劃及綠遷(qian)手續(xu)辦(ban)理(li)、洽商進場(chang)、設(she)備(bei)采購供貨、電力設(she)備(bei)安裝調試、施(shi)工(gong)(gong)驗(yan)收(shou)、送(song)電等全部(bu)工(gong)(gong)作。該項目位(wei)于綠化帶內(nei),地(di)理(li)位(wei)置特(te)殊,只能在有(you)限的(de)(de)范圍內(nei)進行施(shi)工(gong)(gong),且需要辦(ban)理(li)綠遷(qian)、占掘(jue)路(lu),施(shi)工(gong)(gong)過程困難大(da),手續(xu)程序繁多,但(dan)為了保證按(an)時完(wan)(wan)成(cheng)送(song)電,八(ba)號線公司(si)提(ti)前(qian)謀劃、精心組織、嚴格管理(li),在青島市(shi)各(ge)(ge)相關部(bu)門、地(di)鐵集(ji)團、供電公司(si)的(de)(de)大(da)力支持與(yu)幫助下,最終高質量高標準的(de)(de)提(ti)前(qian)完(wan)(wan)成(cheng)了各(ge)(ge)項工(gong)(gong)作并順利完(wan)(wan)成(cheng)送(song)電任務。

青島(dao)地(di)鐵(tie)(tie)8號(hao)線分線箱新建工程(cheng)順利送電是8號(hao)線建設(she)過程(cheng)中的(de)一個重大節點。展現了(le)地(di)鐵(tie)(tie)建設(she)者(zhe)攻堅(jian)克(ke)難的(de)精神,不僅為1號(hao)線供(gong)電提供(gong)了(le)保障,同時也為地(di)鐵(tie)(tie)8號(hao)線后(hou)續供(gong)電接入奠定了(le)堅(jian)實的(de)基礎,為建設(she)開放、現代(dai)、活力、時尚的(de)青島(dao)再(zai)添“新動(dong)能”。
