富水地层条件下盾构机铰接密封保护技术研究

Research on Protection Technology of Shield Machine's Articulation Seal in Water-rich Strata

以南昌地铁1号线6标为背景,为预防盾构机穿越南昌地区富水地层时铰接密封的渗漏,通过分析其结构及工作原理,研究了铰接密封损坏的原因,对原设备系统进行了优化并形成铰接密封保护关键技术,提高了铰接密封的可靠性及可用性。

In order to protect articulation seal of shield tunneling machine from leaking in water-rich strata based on the project of Nanchang Metro Line 1, through analysis of the structure and the operational principle of articulation seal and the reason that articulation seal loses effectiveness, the key protection technology of articulation seal is formed by optimizing the original equipment system, which improves reliability and availability of articulation seal.
