Space-saving interlocking dock-type ecological retaining wall structure and construction method thereof

Abstract

The invention provides a space-saving interlocking dock-type ecological retaining wall structure and a construction method thereof. The structure comprises a water-permeable ecological dock-type retaining wall base; a base reverse filter structure and a retaining wall foundation are arranged under the base; multiple layers of ecological building blocks interlocked vertically are stacked on the base to the top of a bank slope; corresponding plantings is arranged on the surfaces of the ecological building blocks; a reverse filter structure behind a wall is arranged behind the building blocks; and railings and flood prevention channels are arranged at the top of the slope. The retaining wall base adopts a dock-type structure, the construction earth excavation volume of the retaining walls onthe two sides can be effectively reduced, and the impact of construction on the surrounding environment is reduced; support grade beams and diagonal bracing grade beams are arranged in a base riverbedarea for bearing structural bending moment and stress; the water permeability of the riverbed is improved while the material consumption is reduced, water and soil exchange of river channels is facilitated, and the water quality is improved; and the multiple layers of ecological building blocks interlocked vertically are arranged on the base, concave lock catches and convex lock catches are adopted by the upper building block layer and the lower building block layer for buckling and fixing, anti-sliding convex ridges are arranged on the front portions and the rear portions for sliding prevention, and the integrity and safety are improved compared with those traditional ecological building block retaining walls.

Description

technical field [0001] The invention relates to an ecological revetment structure, in particular to a space-saving interlocking dock type ecological retaining wall structure and a construction method thereof, which is suitable for situations where river channels are narrow and site excavation conditions are limited. Background technique [0002] In river engineering, it is often encountered that the river channel is narrow and the site excavation conditions are limited, such as close to houses on both sides of the river channel, important access roads, etc. Some retaining walls that can save construction space have begun to be applied. The dock-type retaining wall structure It is widely used, but it still has various problems: [0003] 1. The dock-type retaining wall is a fully enclosed reinforced concrete structure, the pattern is monotonous and repetitive, and no greening can be planted at all, and the landscape effect is very poor; [0004] 2. Dock-type retaining wall Th...

AI Technical Summary

Problems solved by technology

[0003] 1. The dock-type retaining wall is a fully enclosed reinforced concrete structure, the pattern is monotonous and repetitive, and no greening can be planted at all, and the landscape effect is very poor;

[0004] 2. Dock-type retaining wall The river bed and the retaining walls on both sides generally only have small-diameter drainage holes on the bottom plate and side walls, which are easy to block and easily isolate the water and soil exchange around the revetment. The water quality of the river is easily affected and the ecological effect is not good.

[0005] 3. The dock-type retaining wall is often a fully enclosed reinforced concrete structure. The amount of reinforced concrete is large, the cost is high, and it needs to be poured on site. The construction period is long, time-consuming and laborious

[0008] 5. For the greening effect, the blocks are often provided with holes, but the lack of effective soil fixation measures is likely to cause water and soil loss of the soil behind the wall, threatening the safety of the structure;

[0009] 6. The blocks generally only have holes on the upper part and the water side, and there are no holes on the soil side and the bottom plate of the block. Not only the amount of reinforced concrete is large, but also the soil water and soil exchange inside the block and behind the wall is insufficient, and the ecological effect is not good. good;

[0010] 7. At present, the main structure of most ecological blocks is a hard structure, and the diameter of the greening hole is small, the effect of vertical greening is not very ideal, and there is still room for improvement
