| 熱力隧道下穿既有地鐵線施工綜合防護(hù)技術(shù)(50 卷) |
| 英文標(biāo)題 |
| Comprehensive protective technology for existing metro line during construction of heat-supply tunnel passing underneath |
| 摘要 |
| 熱力隧道下穿北京2號(hào)線地鐵區(qū)間，結(jié)合工程的特點(diǎn)及根據(jù)周邊實(shí)際情況，采用全斷面超前深孔注漿進(jìn)行土體加固，同時(shí)在型鋼拱架上利用千斤頂對(duì)上部地鐵結(jié)構(gòu)進(jìn)行保護(hù)，地鐵結(jié)構(gòu)沉降控制在2.5 mm范圍內(nèi)，保證地鐵2號(hào)線在施工期間不減速。 |
