摘要: 为解决盾构螺旋机驱动密封故障问题,以重庆地区盾构施工情况为依托,结合多台盾构螺旋输送机驱动密封的修复经验,重点分析螺旋输送机驱动密封产生故障的原因: 螺旋机设计不合理、螺旋机螺杆倾斜、筒体连接面磨损、螺杆向前蹿动、油脂注入量不足。总结出新的故障处理(螺旋机结构优化、渣土改良、合理选择螺旋机转速、防止空仓掘进、严控加工工艺等)与预防措施(螺旋机叶片修复、改善油脂注入量、更换损坏部件)。为今后盾构施工中处理螺旋输送机驱动密封故障处理与防护技术提供依据。

Abstract: The causes for the malfunctions of the drive sealing of screw conveyors of shield machines, such as irrational screw conveyor design, inclining of screw rod, damage of contacting surface of the screw conveyor case, leaping forward of the screw rod and inadequate grease injection, are analyzed, and countermeasures, including screw conveyor structure optimization, ground conditioning, rationally selecting the screw conveyor speed, avoiding boring with empty chamber and controlling the manufacturing process, are proposed, with the practice in Chongqing as an example. The paper can provide reference for the coping with the malfunctions of the drive sealing of screw conveyors of shield machines in similar projects in the future. 
