Problems solved by technology

At the same time, hole-type slope protection also has disadvantages. If the hole design is too small, the plant growth space will be small and the green area will be small; if the hole is too large, the soil in the hole will be easily scoured, causing loss and affecting the stability of the slope.

Abstract

The invention discloses vegetation concrete for slope protection and a preparation method of the vegetation concrete. The vegetation concrete comprises the following components in parts by weight: 78-94 parts of cement, 75-86 parts of gravels, 23-27 parts of a mineral mixture, 33-38 parts of a plant-growing matrix, 31-34 parts of grass seeds, 85-100 parts of water and 0.3-0.5 part of a water reducing agent. The mineral mixture is mainly prepared from 11 parts of fly ash, 9 parts of blue algae, 8 parts of zeolite, 7 parts of attapulgite, 7 parts of magnesium silicate and 6 parts of polypropylene. The plant-growing matrix is prepared from natural soil, plant ash, ferrous sulfate and zeolite. By stirring and mixing the cement, the gravels, the mineral materials, the water and the water reducing agent step by step, flattening by a press machine, curing to form porous concrete, pouring the vegetation matrix slurry, and sowing grass seeds to obtain vegetation concrete, the vegetation concrete has the characteristics of high porosity and high compressive strength, and can be applied to slope protection.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to plant-growing concrete for slope protection and a preparation method thereof. Background technique [0002] At present, the following three technologies are mainly used in the field of slope protection in my country: natural vegetation slope protection technology, hard dense slope protection technology, and hole type slope protection technology; the construction technology of these three slope protection technologies is relatively mature and has been widely used. There are also problems of varying degrees, mainly reflected in; [0003] 1. The natural vegetation slope protection technology is to plant plants on the slope, and use the plant root system to entangle in the soil to improve the soil shear strength and insect resistance, so as to maintain the stability of the slope. Although vegetation slope protection has excellent greening effect and certain slope protection effect, ...
