Plank rode type ecological bank protection

Abstract

The invention belongs to the field of river channel bank protection design and environmental ecological engineering, and particularly provides a plank road type ecological bank protection. According to the technical scheme, the ecological bank protection is a step-type composite slope, and a lower-level gentle slope, a higher-level gentle slope and a water bank slope are outwards and upwards arranged along a navigation area of a river channel in sequence; a lower-level retaining wall is arranged between the navigation area and the lower-level gentle slope, and the higher-level retaining wall is arranged between the lower-level gentle slope and the higher-level gentle slope; and a pile leg of a first fixed supporting pile is poured into the lower-level retaining wall, an anti-wave baffle isarranged on the outer side of the first fixed supporting pile through an anti-wave baffle fixing rod, a pile leg of a second fixed supporting pile is buried into a slope base in the range of the lower-level gentle slope and the higher-level gentle slope in an inserted mode, and an anti-wave plank road is arranged on the first fixed supporting pile and the second fixed supporting pile. The plank road type ecological bank protection is suitable for a navigable river channel and a river bank or lake bank violently scoured by winds and waves, can be used for recovering and reconstructing rivers and lakeside zone aquatic plant communities, preventing the adverse effects of ship wave on growth of aquatic plants, and has good landscape performance and hydrophilicity.

Description

technical field [0001] The invention belongs to the field of river revetment design and environmental ecological engineering, and relates to a revetment structure suitable for navigable rivers and river banks or lake banks with severe wind and waves washing, and having ecological, landscape and economic benefits. Background technique [0002] At present, the bank revetment construction schemes adopted by navigable rivers basically adopt the channel design of the vertical high retaining wall, the inclined or stepped design of the hardened slope surface, to resist the impact of the water flow and the wave of the ship on the bank slope, so as to ensure flood passage and navigation. security purposes. This design scheme has the following negative effects: 1. The hardened revetment isolates the connection between the river channel and the coastal zone, blocking the water cycle; The integrity of the river ecosystem; 3. The habitat of aquatic plants is encroached and destroyed, an...

AI Technical Summary

Problems solved by technology

These types of revetments solve the problems of excessive hardening of traditional revetment structures, blockage of land and water circulation, encroachment of aquatic plant habitats, weakening of self-purification ability of water bodies, and poor landscape effects.

However, there are also the following problems: first, there is no wave-absorbing structure, and it is difficult to eliminate the impact of ship waves on aquatic plants, making it difficult for aquatic plants to survive; second, the design of aquatic plant planting areas is not reasonable enough

In the technical scheme disclosed by the application publication number CN108677869A, there is no distinction between submerged plants and emergent plants in terms of water depth. In the technical scheme disclosed by the application publication number CN108978590A, the submerged plant planting area is too narrow, which is not conducive to optimizing aquatic life. The structure of plant communities and the construction of complex water ecosystems; the third is the lack of hydrophilic platforms and insufficient hydrophilicity
