Bundle stack ecological slope protection structure and construction method thereof

Abstract

The invention provides a bundle stack ecological slope protection structure and a construction method thereof. The bundle stack ecological slope protection structure comprises piles and soil blockingbundle stacks, wherein the piles are driven into a soil body; the soil blocking bundle stacks are leaned onto the piles driven into the soil body, and are flatly laid onto the slope surface in an end-to-end connection way to form strip-shaped soil blocking structures; a certain included angle is formed between the strip-shaped soil blocking structures and the slope surface contour line; the strip-shaped soil blocking structures are in layered arrangement along the slope surface; the lower end of each soil blocking bundle stack is connected with a water flow groove; the water flow groove can also be replaced by a water discharge bundle stack; bottom layer filling soil and upper layer filling soil cover the slope surface between the soil blocking bundle stacks; a three-dimensional screen padis buried in the upper layer filling soil; grass seeds are spread in the upper layer filling soil; and non-woven fabric or plant fiber blanket covers the upper layer filling soil. The bundle stack ecological slope protection structure and the construction method provided by the invention have the advantages that the problems of flushing of precipitation on bank slopes and vegetation growth nonuniformity can be effectively solved; the stability of slope roadbeds is ensured; and the covering layer can also achieve the moisture preservation and heat insulation effects. When the bundle stack ecological slope protection structure and the construction method are applied to slope ecological protection engineering, good ecological slope protection effects can be achieved.

Description

technical field [0001] The invention relates to an ecological slope protection structure, which belongs to the field of ecological slope protection. Background technique [0002] Many slopes (especially embankment slopes) are filled with sand and gravel, which cannot meet the conditions for plant growth; although some slopes are made of soil or soil mixed with rocks, they often lack nutrients and microorganisms, and did not grow in the early stage. It is conducive to the growth of plants. In the early stage of construction, these slopes lacked the necessary measures to maintain water and soil on the slopes due to the fact that the slopes were not covered by plants. After being washed by rainfall, dense gullies were formed, which seriously affected the integrity and safety of the slopes. . [0003] For the treatment of this type of slope, because the slope is mostly between 30°-60°, the actual project often adopts mortar rubble slope protection, primary lining arch + six-edg...

AI Technical Summary

Problems solved by technology

[0004] For slopes with traffic conditions at the top of the slope, when the technical scheme of dumping topsoil at the top of the slope and letting the topsoil roll down and cover the slope, and then sow greening, most of the topsoil rolls to the foot of the slope during the rolling down process, and only a small amount The topsoil is kept on the slope. In order to make the entire slope reach the required covering soil thickness, a large amount of topsoil is required, which leads to an increase in treatment costs and unsatisfactory restoration of the slope.

And when this scheme is adopted, the entire slope surface is exposed loose topsoil in the early stage, which is prone to serious soil erosion or surface sliding during rainfall, which affects the stability of the soil and is not conducive to the establishment of a stable ecosystem on the slope surface.
