Bolt machine, also known as soil nail machine, anchor drilling machine or pneumatic impact machine, is mainly used for rock and soil anchor, roadbed, slope treatment, underground deep foundation pit support, tunnel surrounding rock stability, prevention of landslide and other disasters, underground engineering support and high-rise building foundation treatment. It is also suitable for non-prestressed anchor support of deep foundation pit spray protection and slope soil nailing engineering. Bolting machine is suitable for soil nails made of various materials (such as angle steel, threaded steel, steel pipe, etc.).
