What is a bolt support?

Bolt support is to drill the anchor eye into the surrounding rock, then install the anchor in the anchor eye, connect the broken rock body into a whole, and artificially strengthen the surrounding rock to maintain the stability of the roadway. The process is to first fill the anchor eye with cement mortar and then insert the steel bar. It anchors the rock layer with the adhesion of mortar and steel, mortar and hole walls. In the actual application process, the steel wire rope can also be used instead of the steel bar. Other anchor further comprises an inverted wedge anchor metal, wood bolt, bolt resin, rapid hardening cement anchors, anchor pipe joints, retractable bolt and the like.
