以某市地铁长顺街站~骡马市站盾构区间盾构姿态出现异常为例,对盾构纠偏面临的主要风险进行了分析,给出了盾构机纠偏的具体技术措施;实践证明,通过补勘、降水、换刀、盾构掘进控制、盾尾管片注浆封环、房屋预处理及调线等技术可解决盾构机姿态偏离问题,保证盾构施工顺利进行,并为今后类似工程提供借鉴和参考。
Taking the unusual appearance of the shield posture of the Shunchangjie station to the Luomashi station of a certain city as an example, the main risks to the deflection correction of the shield are analyzed, and the specific technical measures for the correction of the shield machine are given. , The problems of attitude deviation of the shield machine can be solved through the technologies of complementing, precipitation, tool change, shield tunneling, grouting ring of shield tail pipe, house pretreatment and transfer line, etc., to ensure the smooth progress of shield construction and Similar projects in the future to provide reference and reference.
