Benefits & Features
As an important part of the anchor support system, the performance of the anchor tray directly affects the support effect of the anchor. The function of the tray is to transfer the thrust generated by the tightening torque of the nut to the top wall, developing the initial anchor force, and at the same time, 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 fence. Therefore, when selecting a tray, the first thing to consider is the matching of the anchor tray and the anchor rod body in strength, to avoid the phenomenon of anchor rod perforation due to insufficient strength of the anchor tray. The second thing to consider is the matching of the anchor tray and the anchor rod body in the support structure, to avoid uneven force on the anchor rod body and nut due to the mismatch between the anchor rod body and the tray in the support structure, which affects the support effect of the tunnel.
