7. A construction method for an ecological retaining wall according to any one of claims 1 to 6, comprising the steps of:
s1, removing accumulated sludge on the surfaces of a river channel and a river channel side slope, and digging out partial original soil of the river channel side slope so as to enable the upstream surface of the river channel side slope to be arranged in a step shape;
s2, pouring broken stone particles into a part of the river channel, which is close to the side slope of the river channel, and paving the broken stone particles to form a bearing platform (5);
s3, sequentially placing all the pieces of the bases on a bearing platform (5), reserving gaps between the bases and the river side slopes, and backfilling the backfilling material (3) in the gaps between the base (1) and the river side slopes after the pieces of the bases are installed;
s4, installing each first baffle (21) on a base (1) formed by each base, enabling the water back side of each first baffle (21) to extend out of the water back side of the base, and enabling the water back side of each first baffle (21) above the foundation to be lapped on the backfill (3) formed in the step S3;
s5, backfilling the backfilling material (3) in a gap between the first baffle (21) and the river side slope after the first baffles (21) are installed;
s6, installing each second baffle body (22) between any two first baffle bodies (21) which are adjacently arranged, enabling the water back side of each second baffle body (22) to extend out of the water back side of the first baffle body (21), and enabling the water back side of each second baffle body (22) above a foundation to be lapped on the backfill (3) formed in the step S5;
s7, backfilling the backfilling material (3) in a gap between the second baffle (22) and the river side slope after the second baffles (22) are installed;
and S8, paving a reinforced concrete member (41) on the top of the finally formed backfill (3) to form the river bank pavement cover plate.
