Miniature pile bridge structure for surface mine slope support

The invention discloses a micro pile bridge structure for surface mine slope supporting, and belongs to the technical field of slope supporting engineering, the micro pile bridge structure comprises a bridge deck, micro piles and pre-stressed anchor cables which are arranged on a slope crest walking platform, the micro piles are vertically arranged, pile bodies of the micro piles penetrate through a fault structure, the bridge deck is arranged at the tops of the micro piles, and the pre-stressed anchor cables are arranged at the bottoms of the micro piles. The micro piles and the bridge deck form a reinforced concrete supporting structure, and the pre-stressed anchor cables are arranged on the slope surface of the surface mine slope and penetrate through a potential sliding surface and a fault structure developed in the slope body. According to the method, a plurality of pre-stressed anchor cables are implemented on the slope surface at the initial stage of formation of the surface mine slope and before geolo
