雙層下穿地道疊合段完成施工
今天（9月2日），繼宿松路快速(su)(su)化改造(zao)工(gong)(gong)程首個放行節點——花園(yuan)大道跨線(xian)橋放行通車后，由安徽(hui)省(sheng)交通建設股份有(you)限公司承(cheng)建的宿松路快速(su)(su)化改造(zao)改造(zao)工(gong)(gong)程2標段工(gong)(gong)程再次(ci)迎(ying)來重要節點——雙層下穿(chuan)地(di)道疊合段完成(cheng)主體結(jie)構(gou)施工(gong)(gong)，三(san)期導改圓(yuan)滿結(jie)束！
宿(su)松路2標段北起繞城高(gao)速南至(zhi)慈光路，長2.815km。雙層下穿疊合段長32m、寬34m，開(kai)挖(wa)深度17m，現場作業空間狹小、支(zhi)撐密集、土(tu)方開(kai)挖(wa)量大、多工(gong)序交叉作業，需完成樁基、支(zhi)撐、土(tu)方開(kai)挖(wa)、墊(dian)層、防水、底板、側墻及中墻、換(huan)撐、中板、頂板、拆撐、回(hui)填等多道工(gong)序，作業危(wei)險(xian)(xian)因素多，現場施工(gong)風(feng)險(xian)(xian)高(gao)。
開工(gong)(gong)以來，安徽交(jiao)建宿松路2標段(duan)充(chong)分發揮科技引(yin)領作用，為工(gong)(gong)程建設高質量(liang)推(tui)進提供“加速(su)度”。為控制施(shi)工(gong)(gong)安全(quan)風險，保障項(xiang)目(mu)順(shun)利推(tui)進，項(xiang)目(mu)部(bu)利用BIM+GIS技術模(mo)擬推(tui)演(yan)，優化空(kong)間布置及施(shi)工(gong)(gong)時序安排，同(tong)時采用智(zhi)能(neng)物聯網技術實(shi)現(xian)對(dui)深基坑的(de)動態監測、通過智(zhi)慧工(gong)(gong)地平臺實(shi)施(shi)風險預警，確保施(shi)工(gong)(gong)安全(quan)。
本次(ci)導改完(wan)成后，將進(jin)行疊合段南側5個(ge)(ge)暗(an)埋段施(shi)工(gong)(gong)。截止目(mu)前，宿松(song)路下穿已(yi)完(wan)成32個(ge)(ge)節段底(di)板、16個(ge)(ge)節段頂板施(shi)工(gong)(gong)，各項工(gong)(gong)作穩步推(tui)進(jin)，力爭(zheng)春(chun)節前完(wan)成宿松(song)路地道主體結構施(shi)工(gong)(gong)。（通訊員 楊帆）
