The difference between left-handed and right-handed bolt
The characteristics of the left-handed bolt: The left-handed non-longitudinal rib threaded steel resin bolt has high strength, reasonable structure and large pre-tightening force; it can actively adjust the direction of the force, increase the binding force on the surrounding rock, and complete the mechanized fast device. It can be end anchor, lengthened anchor and full anchor. It is mainly used for high-strength support of large-deformed roadways in high ground pressure mines, and can also be used for high-strength roadway support of various projects such as railways and hydropower.
Introduction and characteristics of right-handed resin rock bolt?
Right-handed bolt, also known as equal-strength threaded steel bolt, is a tool for determining the anchoring force. It has the characteristics of small size, light weight, easy portability, and simple operation. It is widely used in coal, national defense, tunnels and transportation. Plant tunnel work.
Features of right-handed resin rock bolt:
(1) The structure is reasonable, and the full length of the bolt's full thread is strengthened to deal with the shortcomings of the low strength of the reverse twist bolt thread and the flattened part.
(2) The bearing capacity of the same standard anti-twist bolt is improved by 40%.
(3) Simple operation and low price, it is widely used in various types of roadway support in coal mines, railways, hydropower and other projects.
