Ecological structure and reconstruction method of vertical type bund in tidal river reach

Abstract

The invention discloses an ecological structure and reconstruction method of a vertical type bund in a tidal river reach. The ecological structure comprises a river bed, a retaining wall and a plurality of planting platforms with different heights, the river bed is provided with a presser foot platform and a slope, the retaining and the planting platforms are all located on the presser foot platform, the plurality of planting platforms are distributed in a ladder-like order, the highest planting platform is located at one side close to the retaining wall, the lowest planting platform is located at one side away from the retaining wall, and plants are respectively planted on each planting platform. The ladder-like distribution of the plurality of planting platforms can adapt to the tidal river reach with frequent fluctuations, combined with the typical tide level characteristics, riverine wetlands are built to provide abundant habitats for river biology, thereby improving the diversityof the river biology and landscape space; in addition, the plurality of planting platforms further serve as temporary multistage rescue platforms to facilitate the standing and climbing of drowning persons and rescue workers, thereby improving the safety of the tidal river reach. The ecological structure and reconstruction method of the vertical type bund in the tidal river reach are used in the field of urban river construction and reconstruction.

Description

technical field [0001] The invention relates to the field of construction and transformation of urban rivers, in particular to an ecological structure and a transformation method of a vertical embankment of a tidal river section. Background technique [0002] With the rapid development and construction of the city, the land for urban construction is becoming increasingly scarce, and a large number of river sections in the central urban area are on guard, that is, urban river sections, and retaining walls are often used to defend against the threat of tides and floods. Tidal river section refers to the river section whose flow and water level are affected by tides, that is, the high tide level and low tide level often change, and the river surface height often fluctuates. The retaining wall rises vertically from the platform at the foot of the embankment to the flood control level of the top of the embankment, and there are no slopes and intermediate platforms on the side.

AI Technical Summary

Problems solved by technology

Although the retaining wall provides a wide and flat embankment platform as a space for civic activities, the river bank is a rigid concrete vertical surface, which makes it difficult for vegetation to grow, the ecological landscape effect is poor, and the ecological system is unstable; it is also not conducive to the rescue of people who fell into the water
