Embodiment 1

[0051] This embodiment provides a double-layer concrete ecological slope protection, which includes a first concrete layer and a second concrete layer.

[0052] Wherein, the first concrete layer is made of the first material, and the first material includes 1000 parts of the first aggregate, 150 parts of the first binder and 66 parts of the first aqueous solution. In addition, the weight ratio of the first binder to the first aqueous solution is 1:0.44. The particle diameter of the first aggregate is 20mm, and the average pore diameter is 4mm. The second concrete layer is made of the second material, and the second material includes 1000 parts of the second aggregate, 120 parts of the second adhesive material and 45 parts of the second aqueous solution. The particle diameter of the second aggregate is 5mm, and the average pore diameter is 0.001mm. That is to say, the first concrete layer is made of coarser first aggregate, while the second concrete layer is made of finer sec...

Embodiment 2

[0055] A double-layer concrete ecological slope protection provided in this embodiment includes a first concrete layer, a second concrete layer and a nutrient substrate poured into the first concrete layer.

[0056] Wherein, the first concrete layer is made of the first material, and the components of the first material include 800 parts of the first aggregate, 100 parts of the first adhesive material and 44 parts of the first aqueous solution. In addition, the weight ratio of the first binder to the first aqueous solution is 1:0.44. The particle diameter of the first aggregate is 40mm, and the average pore diameter is 6mm. The second concrete layer is made of the second material, and the components of the second material include 800 parts of the second aggregate, 100 parts of the second adhesive material and 24 parts of the second aqueous solution. The particle diameter of the second aggregate is 13 mm, and the average pore diameter is 0.01 mm. Since the first concrete laye...

Embodiment 3

[0059] A double-layer concrete ecological slope protection provided in this embodiment includes a first concrete layer, a second concrete layer, a first wire mesh layer and a second wire mesh layer.

[0060] Wherein, the first concrete layer is made of the first material, and the components of the first material include 800 parts of the first aggregate, 100 parts of the first adhesive material and 44 parts of the first aqueous solution. In addition, the weight ratio of the first binder to the first aqueous solution is 1:0.44. The particle diameter of the first aggregate is 30 mm, and the average pore diameter is 5 mm; the components of the second material include 800 parts of the second aggregate, 100 parts of the second binder and 24 parts of the second aqueous solution. The first screen layer is installed at 1 / 2 of the height of the first concrete layer. The second concrete layer is made of a second material, the particle size of the second aggregate is 8 mm, and the averag...

Abstract

The invention relates to the field of ecological slope protection, and provides double-layer concrete ecological slope protection. The double-layer concrete ecological slope protection comprises a first concrete layer and a second concrete layer, wherein the first concrete layer is made of first materials, the second concrete layer is made of second materials, the second concrete layer is poured to the surface of the first concrete layer, the first materials include first aggregates of which the particle size is 20 to 40 mm and the average pore size is 4 to 6 mm, and the second materials include second aggregates of which the particle size is 5 to 13 mm and the average pore size is 0.001 to 0.01 mm. The double-layer concrete ecological slope protection is favorable for plant growth, and the conditions of water and soil loss and the collapse of the slope protection are difficult to occur. In addition, the invention further provides a laying method of the double-layer concrete ecological slope protection. The laying method comprises the steps of preparing the first materials and the second materials according to the components, pouring the first materials to a foundation pit so as to form the first concrete layer, and pouring the second materials to the surface of the first concrete layer so as to form the second concrete layer.

Description

technical field [0001] The invention relates to the field of ecological slope protection, in particular to a double-layer concrete ecological slope protection and a laying method thereof. Background technique [0002] At the beginning of the 21st century, dry-laying, mortar-laying, and cast-in-place concrete were often used for slope protection of expressways and water areas. We certainly know that the slope protection is reliable in terms of erosion resistance and stability, but it causes serious water pollution and damages the ecological environment of animals and plants. It is getting worse and worse, and the overall appearance is not good. Nowadays, a consensus has been reached on water purification and increasing emphasis on the ecological environment, resulting in various ingenious ecological slope protection designs, such as plant residue-based ecological slope protection, mesh fiberglass geogrid paving fish pond slope protection, and vegetation concrete greening tech...
