Combined ecological revetment structure and construction method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the field of revetment protection for rivers, lakes and other landscape water bodies, in particular to an ecological revetment structure, in particular to a combined ecological revetment structure capable of planting aquatic plants in comprehensive river channel improvement projects and its construction method . Background technique [0002] The revetment is located at the junction of the water area and the land, and is a hydraulic structure that protects the river bank. The purpose of revetment construction is to stabilize the river and prevent bank collapse or hydraulic erosion. River revetment protection is an important part of comprehensive river improvement. Whether its design is reasonable or not is directly related to the safety and appearance of the entire river, and is of great significance to the prosperity of the city and the improvement of the surrounding environment. [0003] Previous revetment projects focused o...

AI Technical Summary

Problems solved by technology

This kind of revetment structure transforms the river bank into reinforced concrete and stone revetment, like an airtight wall, lacking the channel for the exchange of soil and water environment substances, blocking the communication between water and the bank, making the original growth on the bank slope The organisms cannot continue to grow, destroying the integrity of the ecosystem and causing adverse effects on the environment and ecology
