【摘要】：長(zhǎng)沙地鐵芙蓉廣場(chǎng)站受前期拆除立交橋引橋影響,導(dǎo)致主體施工進(jìn)度滯后,嚴(yán)重影響盾構(gòu)過(guò)站始發(fā)掘進(jìn),即使采用站外過(guò)站分體始發(fā)也要使盾構(gòu)停機(jī)等待7個(gè)月,無(wú)法滿足業(yè)主要求盾構(gòu)在五一廣場(chǎng)站吊出轉(zhuǎn)場(chǎng)后當(dāng)年還建立交橋要求,工期矛盾突出。采用先施工站臺(tái)層方案,運(yùn)用側(cè)墻和中板一次澆筑工藝和早強(qiáng)混凝土及時(shí)為盾構(gòu)提供接收條件。研發(fā)出曲線導(dǎo)軌滾輪整機(jī)過(guò)站實(shí)現(xiàn)了盾構(gòu)過(guò)站與站臺(tái)層平行施工。通過(guò)站臺(tái)層中板配筋加強(qiáng)解決了盾構(gòu)過(guò)站始發(fā)后再施工車站剩余主體難題。首次實(shí)現(xiàn)盾構(gòu)始發(fā)掘進(jìn)與車站主體工程平行施工,大大縮短建設(shè)工期。
[Abstract]:The subway station Changsha Furong square by the early removal of overpass bridge approach, leading to the main construction progress lag, seriously affected the originating station tunneling shield, even with the station outside the station separate launching will make the shield down to wait for 7 months, can not meet the requirements of shield hanging out transitions in 51 square station was built for interchange bridge, duration of contradiction. The construction of the platform layer scheme, side wall plate and the use of a casting process and early strength concrete to provide timely shield reception conditions. The development of curve rail roller machine had realized the station subway station and the platform layer. Through the parallel construction platform layer plate reinforcement strengthening solution station after the construction of the shield originating station for the first time. The main problem of the remaining shield original heading parallel with the main station construction project, greatly shorten the construction period.
