介绍锚杆应用及常用的拆锚方法,针对现有前混合磨料射流退锚装置存在锚杆拆卸时间长、工人作业环境差、装置部件锈蚀维护性差等问题,提出了一种前混合磨料射流退锚改进装置,并进行现场试验,结果表明,所改进设计装置具有退锚时间短、对工人伤害小、操作简便、部件维护周期长和无需专门配备泵站等特点,对进一步提高锚杆拆除效率具有重要参考价值。
This paper introduces the application of anchor rod and the commonly used method of dismantling anchor. In view of the problems such as long bolt disassembly time, poor working environment of workers and poor corrosion protection of the components of the existing pre-mixed abrasive jet return anchor, a pre-mixed abrasive jet ejecting The results show that the improved design device has such advantages as short back-off time, less harm to workers, simple operation, long maintenance period of components and no need of specially equipped pump stations, which further improves the efficiency of bolt removal Has important reference value.
