管棚与注浆技术在隧道突泥中的应用
The application of pipe roof and grouting technology in tunnel burst mud
【摘要】 针对某隧道在施工中发生的突泥灾害,借助TSP-203超前地质探测仪对掌子面前方的地质条件进行了探测,采用长管棚预支护结合小导管注浆对突泥体及周边围岩进行加固处理,经实际证明此方案对于治理隧道突泥是可行的,为今后在流塑状黏土地质中修建隧道积累了一定的经验。
【Abstract】 Aiming at the burst mud damage occurred in construction of tunnel,the geology condition before tunnel face was detected using TSP-203 advance geologic detection instrument,and the reinforcement treatment was carried out to burst mud and peripheral adjacent rock using long pipe roof pre-supporting combining with small guiding pipe grouting.It was verified that this scheme was feasible to treat tunnel burst mud by practice,which can accumulate experiences for future building tunnel in plastic flow clay geology.
