Problems solved by technology

The gabion gabion is also a gravity-type straight wall structure, but because the wall is mainly made of pebbles and stones, even if the water connection between the front and back of the wall can be ensured, it is difficult to form an overall vegetation cover on the surface of the wall. From an ecological point of view It is not much different from the traditional gravity retaining wall
The self-embedded retaining wall adopts self-embedded blocks, and the filling soil is connected by geogrid to form a composite wall. The wall is equipped with planting holes and other structures to plant aquatic plants and provide places for fish to spawn and take refuge. However, the wall The material is still mainly concrete, and as a flexible structural wall, the strength is low, subject to certain height restrictions
[0005] The conventional ecological straight-wall slope protection based on the above two structures is difficult to achieve both wall stability, ecological protection, and ecological restoration, and both have a certain barrier effect on the water bank slope ecosystem, resulting in ecosystem degradation.

Embodiment 1

[0031] Such as figure 1 As shown, a kind of planting type retaining wall ecological revetment structure described in the present embodiment, a kind of planting type retaining wall ecological revetment structure, it comprises water body bank slope 1 and is located at the water body bank slope 1 facing water surface The retaining wall includes a wooden frame structure 2 spliced ​​by natural wood, a base layer 5, a transition layer 6, an ecological soil layer 7, and a slope that are sequentially arranged in the wooden frame structure 2 from bottom to top. Surface vegetation 8; wherein, the base layer 5 and the transition layer 6 are filled with block fillers, the water level line is not higher than the transition layer 6, and the ecological soil layer 7 is arranged at intervals in the up and down direction Several vegetation soil layers, and some biological branches 9 inserted between two adjacent layers of the vegetation soil layers, the slope vegetation 8 is smoothly connected ...

Embodiment 2

[0039] On the basis of Embodiment 1, the present embodiment further provides a manufacturing method for the above-mentioned ecological revetment structure of a planting retaining wall, which includes the following steps:

[0040] S1, building and fixing natural wood to form a wooden frame structure 2;

[0041] S2. Excavate deeply the toe of the water body bank slope 1, and embed the wooden frame structure 2 in the toe of the slope to fill the base area 5 and the water level change area 6 of the wooden frame structure 2;

[0042] S3, lay earthwork layers layer by layer to the ecological zone 7 of wooden frame structure 2, and place some biological branches 9 between adjacent two layers of earthwork layers;

[0043] S4. Lay the ecological surface layer 8, and make the ecological surface layer 8 and the original bank slope of the water body bank slope 1 smoothly connected.

[0044] In this embodiment, in step S1, steel bar binding or rivets can be used to form the natural wood f...

Abstract

The invention discloses a plant growing type retaining wall ecological bank protection structure. The plant growing type retaining wall ecological bank protection structure comprises a water body bank slope and a retaining wall arranged on waterside face the water body bank slope. The retaining wall comprises a wood frame structure, a base layer, a transition layer, an ecological soil layer and slope vegetation, wherein the wood frame structure is formed in the manner that natural wood is spliced, and the base layer, the transition layer, the ecological soil layer and the slope vegetation are sequentially arranged in the wood frame structure from bottom to top. The normal water level does not exceed the transition layer. The ecological soil layer comprises plant growing soil layers, and a plurality of biological branches are flatly laid between the plant growing soil layers. The slope vegetation is arranged on the top of the vegetation growing soil layers and is in smooth connection with the original bank slope of the water body bank slope. The plant growing type retaining wall ecological bank protection structure meets the bank protection stability requirement, and the plant growing soil layers have the water flow scouring resistance; internal matter exchange between the water body and a soil body cannot be blocked, living space is provided for bank slope organisms, and the ecological system of the water body bank slope is completed; the wood frame structure provides a living site and nutrients for aquatic life, and the improvement of the biocenosis diversity is facilitated; and the plant growing type retaining wall ecological bank protection structure is suitable for water body bank slope protection and meets the requirements for wall stability and ecological remediation performance.

Description

technical field [0001] The invention relates to the field of ecological slope protection, in particular to an ecological revetment retaining wall structure suitable for water body bank slope protection, and a manufacturing method of the ecological revetment retaining wall structure. Background technique [0002] Ecological revetment is a revetment technology that integrates the basic knowledge of engineering mechanics, soil science, ecology and botany to support the slope and form a comprehensive revetment system composed of plants or engineering and plants. After the excavation slope is formed, by planting plants, the interaction between plants and rock and soil (root system anchorage) is used to protect and reinforce the surface of the slope, so that it can not only meet the requirements for the stability of the slope surface, but also can The revetment method to restore the destroyed natural ecological environment is an effective means of revetment and slope consolidation...
