The present invention relates to an automatic and precise pressure control device for grouting anchor rods, comprising an upper clamp, a lower clamp, a bursting disc, a spring, a metal block and a high-pressure resistant metal pipe. The high-pressure resistant metal pipes on both sides of the device can be fixed on the grouting pipeline by quick plugging. When the grouting pressure in the pipeline is greater than the preset value of the bursting disc, the bursting disc is torn apart along the supporting edge and falls off as a whole. The spring returns to its original state, thereby pushing the metal block and the fallen bursting disc into the groove of the lower clamp, preventing the slurry from continuing to flow. The device realizes automatic pressure control, solves the problem that the grouting anchor rod (cable) is overly dependent on manual judgment of the grouting situation, effectively improves the effect of automatic and precise control of the grouting pressure, and ensures the safety of the grouting process.
