The invention relates to a 
cushioning-banking protection and construction method which comprises a reservoir area ploughing sandy gravel 
cushioning-banking ecological water-retention protection technology, a sliding track-based sand 
cushion cloth scraping and dense-vibrating 
system, a shaped hidden track-based 
towing mold large-area concrete panel construction technology, a movable slope surface horizontal mold plate, a belt-moving baffle plate chute concrete pouring 
system, a sliding vibration and flattening manner, a movable manual operation platform, a shaped track-based sliding type mold plate anti-scour tooth wall technology, a door type pouring, scraping and vibrating 
system, a stretching type vibration scraping beam, and a prefabricated combined type non-dismantling mold plate anti-scour tooth wall. The problems of poor integrality, poor compactness and complicated construction of a traditional 
cushioning-banking sand 
cushion, and complicated construction, safety quality potential, mold plate installation, complicated disassembly process and large project amount during slope surface concrete panel and 
retaining wall concrete pouring are effectively solved, the construction process is simple and practicable, the construction efficiency is greatly improved, and the method can achieve a good technique economic performance when being applied to practical 
engineering.
