Construction method of ecological revetment

Abstract

The invention relates to a construction method of an ecological revetment formed by splicing and fixing ecological prefabricated bricks on a protection slope. The construction method comprises the following steps of: (1) mixing cinder, cement, yellow sand and crushed wheatstraw in a valume ratio of 0.4 to 0.1 to 0.3 to 0.2 and then stirring into ecological concrete; (2) making ecological prefabricated bricks with the ecological concrete and arranging trough holes on the prefabricated brick surfaces; (3) laying snail shells with the cut-through tails at one side of the prefabricated bricks before the concrete is dried to form the outer surface of the embankment, wherein the through holes formed on the embankment blocks are not blocked by snail shells; (4) fully drying, filling the through holes and the hollow cavities of the surface snail shells with silt containing herbaceous plant seeds and drying the silt to form the ecological prefabricated bricks; and (5) splicing and fixing a plurality of prefabricated bricks on the protection slope to form the ecological embankment. The invention is suitable for building ecological embankments for rivers and lakes reservoirs and can be also used for paving ecological walls and ecological roads.

Description

technical field [0001] The invention relates to the construction and repair of river courses, lakes, reservoirs and pond bank slopes, in particular to a construction method for ecological revetment, which belongs to the technical fields of environmental protection, water and soil conservation, ecology and landscape restoration. Background technique [0002] Due to the need for flood control and flood control and the weak awareness of ecological environment protection in the past, a large number of hard cement dams have been built on rivers, lakes and other water bodies in my country, which not only blocked the ecological continuity between the water ecosystem and the terrestrial ecosystem, but also destroyed the waterway. The original ecological environment of the ecotone has lost various ecological functions and biodiversity such as retention and digestion of pollutants in the riverbed slope and lakeshore zone, and is not conducive to water and soil conservation, reducing the...

Problems solved by technology

[0004] The ecological concrete of above-mentioned various prior art considers water permeability, porosity aspect more, also has to involve the research of adsorption, but all ignores the preset of water retention and soil retention and plant seed, is unfavorable for the rapid recovery of plant; Consider the environmental requirements for the growth of various plants. For example, emergent plants with creeping underground stems and thicker stems above the ground need larger pores to grow; and some concrete is added with various additives in non-original environments, which is not ecological. idea
