Steel structural self-drilling hollow anchor rod reinforcing existing line support check protective structure

The utility model discloses a steel structural self-drilling hollow anchor rod reinforcing existing line support check protective structure. The protective structure is arranged at side slopes at two sides of a road bed; angle steel nets are horizontally vertically crossed at the surfaces of side slope protective walls from the side slope bottoms to the side slope tops along the direction of the road bed; cushion plates are arranged at the nodes of the angel steel nets; hollow anchor rods penetrating through the cushion plates and the nodes and deepening into the stratums of the side slopes are arranged to be vertical to the side slope protective walls; hollow cavities are arranged in the hollow anchor rods. Anchoring force is generated for a reinforcing body by the self-drilling hollow anchor rods in the stratums behind the existing check walls and protective walls, the anchoring force is uniformly distributed to the wall surface of the reinforcing body by the cushion plates and the angle steel, and the form
