cone rock bolt volcanic plate

The cone rock bolt volcanic plate is to transmit the thrust generated by the locking torque of the nut to the top side to generate the initial anchor force, and at the same time to transmit the pressure of the top side of the roadway to the bolt to generate working resistance, strengthen the surrounding rock together.

Product Description

When choosing a pallet, firstly, it is necessary to meet the strength matching between the anchor pallet and the anchor rod body, so as to avoid the phenomenon of anchor rod perforation caused by insufficient strength of the anchor rod pallet. The second is to meet the matching of the anchor rod tray and the anchor rod body on the supporting structure, so as to avoid uneven force on the anchor rod body and nut due to the mismatch between the anchor rod rod body and the tray on the supporting structure, which will affect the support of the roadway. protection effect.
