Combined ecological revetment structure and construction method thereof
A combined ecological revetment structure comprises a first-stage revetment (1) and a second-stage revetment (2), wherein the first-stage revetment (1) is of a ground frame gabion structure and comprises frame bodies (11) which are square plate frames with openings in the upper and lower portions, and the frame bodies (11) are made of concrete. The frame bodies (11) are regularly placed on a river bank, the tops of the frame bodies (11) are located below a normal water level, and the bottoms of the frame bodies (11) extend to a riverbed. Aquatic plants (13) are planted inside holes in the frame bodies (11), the second-stage revetment (2) is of a coconut fiber blanket structure (21) and is in a net shape, and a seed layer (22) and nutrient soil (23) are sequentially arranged on the upper surface of the second-stage revetment (2) from bottom to top. The coconut fiber blanket structure (21) is fixed to the normal water level and the part, flush with or higher than the normal water level, of the riverbank. The revetment structure is reasonable in structure, economical and practical. The construction method is simple, rapid to implement and capable of being widely applied to shore protection engineering of river channels, lakes and landscape water bodies.
