Double-layer concrete ecological slope protection and laying method thereof

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...

[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

However, the existing ecological slope protection is not conducive to the growth of plants. In addition, its structural strength is insufficient, and it is prone to soil erosion and slope protection collapse.
