Prefabricated prestressed concrete anchor pier for slope reinforcement

The utility model discloses a prefabricated prestressed concrete anchor pier for slope reinforcement. The prefabricated prestressed concrete anchor pier comprises a prestressed concrete anchor pier unit, concrete ribs and anchor head parts, wherein the prestressed concrete anchor pier unit is provided with a cross beam and a longitudinal beam which are intersected into a cross shape; the concreteribs are positioned around the prestressed concrete anchor pier unit; and prestressed reinforcements are arranged in the cross beams and the longitudinal beams. According to the prefabricated prestressed concrete anchor pier, the prestressed concrete lattice beam is adopted, the section performance of the beam can be improved, larger anchoring force can be borne, and the defect that when a traditional cast-in-place reinforced concrete lattice beam encounters large anchoring force of an anchor cable, the traditional cast-in-place reinforced concrete lattice beam can be pulled apart at the midspan position, and conseque
