Light retaining structure for treating cut slope slump

The utility model relates to a light supporting and retaining structure for treating slip collapse of a cutting slope. The light supporting and retaining structure comprises a slope top intercepting ditch, slope surface backfill grouted rubble or rubble concrete, an anchor rod frame beam, a drainage pipe and a slope bottom intercepting ditch. The slope crest intercepting ditch has the functions of stopping water and avoiding rainwater infiltration, and secondary damage to the slope surface caused by rainwater infiltration during construction can be effectively avoided. The whole slope surface is backfilled with mortar rubbles or rubble concrete, the anti-scouring capacity of the surface of the slope body is greatly improved, the anchor rod frame beams are applied, the integrity of the slope body is improved, and the anchor rod frame beams serve as a counter-force device to counteract sliding force generated by a sliding and slump body; the intercepting ditch is applied to the slope toe so as to quickly drain
