Expansive soil cutting slope reinforcing structure and construction method

The invention discloses an expansive soil cutting slope reinforcing structure. The expansive soil cutting slope reinforcing structure comprises a slope surface anti-scouring part arranged on the slopesurface of a slope and further comprises a plurality of reinforcing longitudinal beams which are arranged on the slope surface of the slope and transversely distributed, wherein the bottoms of the reinforcing longitudinal beams are in sawtooth shapes, and the parts, located at the top of the slope, of the reinforcing longitudinal beams are connected with a slope crest anchoring body; and a slopecrest anchoring part is anchored in a slope crest and connected with the slope crest anchoring body, and the parts, located at a slope toe, of the reinforcing longitudinal beams are connected with a reinforcing longitudinal beam foundation. The invention further discloses a construction method of the expansive soil cutting slope reinforcing structure. According to the expansive soil cutting slopereinforcing structure and t
