1. It is strictly prohibited to damage the slope surface at will.
2. Accurately understand the conditions of the water supply and drainage pipelines within 10m of the foundation pit edge, dredge the sewage pipelines to ensure smooth water flow, avoid damaging the water supply pipelines, and eliminate the phenomenon of water inrush inside the slope.
3. Pay attention to waterproofing and drainage at the slope crest and toe. Various construction and domestic water and rainwater must not be discharged directly onto the unpaved ground within 10m of the foundation pit edge, to prevent surface water from entering the slope surface. Ponding water at the slope crest and toe shall be drained promptly; long-term soaking of the slope toe is strictly prohibited.
4. Within 2m of the slope crest, no materials shall be stacked and no large heavy-duty trucks shall pass. The outrigger support points of heavy cranes must be more than 4m away from the slope crest.
