According to the utility model, the primary grouting pipe is freely installed in the circular support frame, the secondary grouting pipe is installed on the side part of the support beam, the support beam plays a role of supporting the secondary grouting pipe, and the primary grouting pipe is combined with the secondary grouting pipe, so that the grouting pipe can be pulled out while grouting is changed in the grouting process, and the grouting quality is ensured.
The support beam is a wave-shaped steel bar welded on the support frame at intervals, so that the support beam is convenient to fix with the support frame and is convenient to bind with the anchor cable. And the wavy reinforcing steel bars can be ensured to be contacted with the wall of the drilled hole to slide more easily when the anchor cable is inserted into the drilled hole.
The supporting beams can also be steel bar groups with radians welded on the supporting frame at intervals, so that the anchor cable can be well limited, and the supporting beams at the positions where the secondary grouting pipes are installed are symmetrical radian-type steel bar groups, so that the secondary grouting pipes can be limited under the condition that the anchor cable is limited and bound, and the stability of the secondary grouting pipes is ensured. The limiting disc is used for tensioning the anchor cable after grouting is completed.
