As an important part of the anchor rod support system, the performance of the anchor rod tray directly affects the support effect of the anchor rod. The function of the tray is to transfer the thrust generated by the locking torque of the nut to the top wall to generate initial anchoring force, and at the same time, to transfer the pressure of the tunnel top wall to the anchor rod, generating working resistance, jointly reinforcing the surrounding rock, and preventing the displacement of the tunnel top wall. So when choosing a tray, one thing is to meet the matching of the strength between the anchor rod tray and the anchor rod body, in order to avoid the phenomenon of anchor rod perforation caused by insufficient strength of the anchor rod tray. The second is to meet the matching between the anchor rod tray and the anchor rod body on the support structure, to avoid uneven stress on the anchor rod body and nut caused by the mismatch between the anchor rod body and the tray on the support structure.
