Abstract
The utility model discloses a sash green ecological protection structure. The protection structure comprises a side slope toe wall foundation and rectangular concrete sashes arranged from the side slope toe wall foundation to the side slope surface layer of a slope crest at intervals. The sash green ecological protection structure is characterized in that geo-grids parallel with the horizontal line are fixedly arranged inside the positions from the side slope toe wall foundation to the side slope surface layer of the slope crest and a filling layer, three-dimensional ecological water draining systems are arranged at the position, between the rectangular concrete sashes, inside the side slope surface layer, and the three-dimensional ecological water draining systems further comprise ecological bag embankments which are arranged in a stacked mode. The regular rectangular concrete sashes are adopted, so that paying off, slotting, formwork erecting, pouring and other constructions are convenient. Due to the fact that the structure is divided into independent units, ecological bags in several sashes can be inlaid at the same time and are not mutually interfered, and construction and maintenance are convenient.
