介绍了盘形滚刀的基本情况及区间地质情况对刀具的磨损影响,全面总结了滚刀的失效形式以及原因,其以正常磨损为主,兼有偏磨、漏油、刀圈断裂、挡圈脱落等非正常磨损,结合重庆盾构项目的施工经验,重点研究了该项目试掘进期间滚刀大量异常磨损原因。根据TBM施工现场数据来研究刀具的消耗问题,定性分析了刀具磨损与刀具自身因素、地质因素、掘进参数等方面的关系。
This paper introduces the basic situation of disc cutter and the influence of interval geology on the wear of cutter. It summarizes the failure form of hob as well as its reason. The ring shedding and other non-normal wear and tear, combined with the construction experience of Chongqing shield project, focus on the reasons for the large number of hob abnormal wear during the trial boring. According to the TBM construction site data to study the consumption of the tool, qualitative analysis of the tool wear and the tool itself factors, geological factors, driving parameters and other aspects of the relationship.
