4月11日,青(qing)島(dao)地鐵(tie)四號線06工(gong)(gong)區(qu)迎來建(jian)設新節點,隨著最后一方混凝土澆筑到位(wei),由中國鐵(tie)建(jian)投資集(ji)團投資、中鐵(tie)十七局(ju)集(ji)團承建(jian)的青(qing)島(dao)地鐵(tie)四號線洪山(shan)坡(po)站主體結構(gou)順利封頂。下一步(bu),該(gai)站點將全面進入附屬(shu)結構(gou)施工(gong)(gong)階段。截(jie)止目前,4號線全線累計封頂車站16座!
據了(le)解,洪山(shan)坡(po)站(zhan)為(wei)青(qing)島(dao)地鐵4號線的(de)第11座(zuo)車(che)(che)站(zhan),為(wei)地下(xia)兩層島(dao)式車(che)(che)站(zhan),車(che)(che)站(zhan)共(gong)設有2個出入口,2組風亭。車(che)(che)站(zhan)全長205.8m,共(gong)分為(wei)三(san)種(zhong)襯(chen)(chen)砌(qi)斷(duan)面,其中擴大段襯(chen)(chen)砌(qi)斷(duan)面二(er)襯(chen)(chen)主體跨度24m,高度17.856m;標準段襯(chen)(chen)砌(qi)斷(duan)面分為(wei)有柱(zhu)和無柱(zhu)兩種(zhong)斷(duan)面二(er)襯(chen)(chen)主體跨度20.3m,高度16.55m。
洪山坡站位(wei)于福遼(liao)立(li)交(jiao)交(jiao)叉口東(dong)側遼(liao)陽(yang)西路(lu)路(lu)中,沿遼(liao)陽(yang)西路(lu)東(dong)西向布(bu)置,遼(liao)陽(yang)西路(lu)為雙向8車(che)道,每日車(che)流量(liang)大,車(che)站西南側靠近醫院(yuan)、社(she)區,施工(gong)難度大。自開(kai)工(gong)建(jian)設以來,地鐵集(ji)團組織項目(mu)部不(bu)斷優化施工(gong)方案,在(zai)全(quan)力確(que)保施工(gong)安全(quan)質量(liang)的前提下,采取(qu)靜態爆破、打設減(jian)振孔(kong)、電(dian)子雷管等施工(gong)技術,控制震速(su)、減(jian)小震動,成功克服爆破、地質復雜(za)、地形西南低東(dong)北高,起伏較大等諸多難題(ti),確(que)保了車(che)站主體結構封頂。
“2020年(nian)受疫(yi)情(qing)(qing)影響(xiang),疫(yi)情(qing)(qing)期間嚴管控(kong),項目(mu)部(bu)開(kai)工(gong)(gong)(gong)(gong)即搶工(gong)(gong)(gong)(gong),專車接(jie)送工(gong)(gong)(gong)(gong)人(ren)返崗,全力調配人(ren)材機進(jin)場,高(gao)效(xiao)實現復工(gong)(gong)(gong)(gong)。今年(nian)項目(mu)部(bu)抓好疫(yi)情(qing)(qing)防控(kong),提倡就地過年(nian),春節期間不停工(gong)(gong)(gong)(gong),全力投(tou)入施(shi)工(gong)(gong)(gong)(gong)生產,截至目(mu)前,洪山坡(po)站(zhan)主體結構(gou)澆(jiao)筑混凝土1.455萬方,主體結構(gou)順利(li)封頂(ding),完成了項目(mu)‘保安(an)全、抓質量、促進(jin)度’的施(shi)工(gong)(gong)(gong)(gong)目(mu)標(biao),為(wei)后續施(shi)工(gong)(gong)(gong)(gong)奠定(ding)了基礎(chu)。”項目(mu)工(gong)(gong)(gong)(gong)程負責人(ren)介紹(shao)道(dao)。
接下(xia)來(lai),洪山坡站全(quan)面(mian)進(jin)入附(fu)屬(shu)結(jie)構(gou)施(shi)(shi)工,項目將(jiang)進(jin)一步優化施(shi)(shi)工方案,全(quan)面(mian)落實(shi)“保(bao)安(an)全(quan)、抓質量、促進(jin)度”的工作要求,保(bao)質保(bao)量完成(cheng)施(shi)(shi)工任務,力爭達到(dao)預定節點(dian)目標(biao),助力青(qing)島地鐵(tie)實(shi)現互聯互通(tong)。
