Beautifying and ecological restoration device and method of urban river hard revetment

The invention provides a beautifying and ecological restoration device of an urban river hard revetment, which comprises a hard revetment, a plurality of replaceable ecological brick boxes which are inlaid in the hard revetment and a water supply pipeline which is inlaid in the upper end of the revetment, wherein ecological soils and plant seedlings are arranged in the ecological brick boxes. With the adoption of the beautifying and ecological restoration device of the urban river hard revetment, by using the ecological brick boxes, a river and the soils can be communicated, conditions are also supplied for the growth of plants on the revetment, a riverway and soils of a riverside zone are not occupied, and the functions of water and soil shielding and sustaining, flood discharging and water drainage of the hard revetment are also kept; and by arranging the water supply pipeline, the plants in the ecological brick boxes are ensured to exit for a long term, the function of water quality purification similar to a surface flow wetland can also be fulfilled, and the purposes of water clearing and river returning are achieved, and therefore, the invention can provide a novel method which can carry out beautifying and ecological purification on the abrupt hard revetment in a city and is easy to operate, thus promoting the development of an ecological reconstruction technology of the hard riverway.
