Double-arch reinforced prestressed steel column high-strength passive protective net

A double-arch reinforced prestressed steel column high-strength passive protective net comprises a plurality of double-arch prestressed steel columns, the bottoms of the double-arch prestressed steel columns are mounted on a base through connecting screws, and one sides of the double-arch prestressed steel columns are fixed in a slope rock surface through anchoring mechanisms; the two adjacent double-arch prestressed steel columns are connected through a supporting mechanism, a rhombus steel rope net is arranged on the supporting mechanism, a grating net is laid and hung on the inner side of the rhombus steel rope net, the rhombus steel rope net and the grating net are matched to form a double-layer protective net structure, collapsed and slippery objects with small sizes can be effectively intercepted through the grating net, and the collapsed and slippery objects with small sizes can be effectively intercepted. Impact energy is transmitted to the rhombic steel rope net, large collapsing and sliding objects
