Further, the steel arch frame and the vertical supporting frame are fixedly connected through a connecting plate; the steel arch frame and the vertical supporting frame are made of I-shaped steel.
Furthermore, the connecting plate is of a hollow I-shaped steel structure, the end parts of the steel arch frame and the vertical support frame are inserted into the hollow I-shaped steel structure of the connecting plate, and the edge of the connecting plate is welded with the steel arch frame and the vertical support frame; the inner side wall of the connecting plate is completely attached to the outer side walls of the steel arch frame and the vertical supporting frame.
Furthermore, the number of the anchor rods is five, two vertical supporting frames are respectively provided with one anchor rod, and the number of the anchor rods on the steel arch frame is three at equal intervals.
Furthermore, through holes are arranged on the steel arch frame and the vertical support frame which are provided with anchor rod positions, stabilizing hooks are arranged in the through holes, one ends of the stabilizing hooks penetrate through the through holes and are inserted into the surrounding rock, and the other ends of the stabilizing hooks are hooked on the steel arch frame or the vertical support frame; the stabilizing hook is connected with the anchor rod in a welding way.
Compared with the prior art, the utility model discloses there is following technological effect:
the utility model adopts an assembly structure, which is convenient for structure transportation and simple in assembly;
the utility model combines the support main body with the anchor rod, and concrete is sprayed between the support main body and the surrounding rock, thereby effectively increasing the contact area between the support main body and the surrounding rock and enhancing the support effect;
the utility model discloses strut the main part and still consolidate through firm hook, further strengthen the stability of strutting the main part.
