Immerseable embankment high slope interlocked ecological brick flexible protection structure and construction method

Abstract

The invention relates to an immerseable embankment high slope interlocked ecological brick flexible protection structure and a construction method. The immerseable embankment high slope interlocked ecological brick flexible protection structure comprises a gravity type retaining wall, an anchor rod anchoring system, a geogrid reinforced embankment, an ecological gabion broken stone hardcore, an interlocked ecological brick surface layer and the like. The construction method sequentially comprises the steps of surface leveling construction, basic retaining wall enlargement construction, horizontal anchor rod layered construction, laying of geogrid, anti-filtration geotechnical cloth and a gabion mesh, filling of embankment filling materials and broken stone bodies near water, and laying of slope interlocked ecological bricks. The geogrid is connected with anchor rods through connection devices; each connection device comprises a vertical groove-shaped component, a horizontal pressing connection plate, a pressing connection bolt, an anchoring body and the like. The immerseable embankment high slope interlocked ecological brick flexible protection structure and the construction method have the beneficial effects of being applicable to embankment filling construction with changes of the water level on the embankment slope side, especially applicable to embankment filling construction having the ecological slope protection requirement, and obtaining good technical and economic benefits.

Description

technical field [0001] The invention relates to a flexible protection construction method of interlocking ecological bricks for high side slopes of flooded embankments, which belongs to the field of embankment filling construction of road engineering, and is suitable for embankment filling construction where water level changes exist on the embankment side slope side, and is especially suitable for ecological bricks. Embankment filling construction required for slope protection. Background technique [0002] The high-slope embankment filled in the section where the water level fluctuates greatly will seep through the pore water in the embankment as the water level fluctuates up and down during road operation. On the one hand, under the action of seepage force, the fine particles in the embankment have Gradually brought out the trend, when the hydraulic gradient is large, the hydraulic gradient near the slope may exceed the allowable hydraulic gradient of the slope soil and c...

Problems solved by technology

[0003] Under the conditions of this project, the method of filling high slope embankments is to set up concrete retaining walls. This method has a good protective effect on high embankment slopes, but the cost is high, and the ecological connection is completely isolated, which is not in line with the development of ecological environmental protection. trend; there are also slopes that use ecological bricks for slope protection. By planting vegetation, etc., good ecological and aesthetic effects have been achieved, the living environment of aquatic animals and plants has been improved, and the quality of water has been purified. However, the protection of slopes is limited, and it is easy to Landslide instability or large deformation occurs; in addition, reinforcement materials such as geogrid are often used inside the embankment to enhance the overall stability and deformation resistance of the embankment, but the interface between the newly filled embankment and the original stratum is a weak surface

[0004] To sum up, although the existing filling construction methods of flooded embankments have achieved certain results under similar construction conditions, there are still some areas for improvement.
