preparation example Construction

[0035] In a second aspect, the application provides a method for preparing the modified expansive soil described in the first aspect, such as figure 1 As shown, the method includes the following steps:

[0036] S1. obtain the dried expansive soil powder;

[0037] S2. mixing the expansive soil powder with cement to obtain a mixture;

[0038] S3. Add water retaining agent, organic fertilizer, peat and polyacrylamide into the mixture and mix to obtain modified expansive soil.

[0039] As an optional embodiment, the fineness of the expansive soil powder is 3-20 mesh.

[0040] Specifically, the expansive soil sample can be dried and crushed. Preferably, the fineness of the expansive soil powder is sieved through a 5mm sieve. The reason for controlling the fineness of the expansive soil powder is to mix it uniformly with other admixtures.

[0041] In a third aspect, the present application provides a cement-modified expansive soil ecological substrate, the components of which inc...

Abstract

The invention relates to the field of expansive soil slope treatment and ecological slope protection, in particular to cement modified expansive soil, a preparation method of the cement modified expansive soil and a cement modified expansive soil ecological base material. The modified expansive soil comprises the following components: 3%-10% of cement, 1%-2% of ferrous sulfate, 0.05%-0.2% of a water-retaining agent, 0.5%-2% of an organic fertilizer, 3%-10% of peat, 0.05%-0.2% of polyacrylamide and the balance of expansive soil. The water-retaining agent is used for realizing water storage and soil conservation capabilities, the organic fertilizer and the peat are used for realizing fertility, the physical and chemical properties and biological activity of soil are improved, and polyacrylamide is used for promoting the formation of a granular structure of a base material mixture, so that fertility factors such as water, fertilizer, gas and heat are coordinated, and the soil-retaining agent has certain fertility and water storage and soil conservation capabilities, can promote the growth of plants, keeps the ecological function of natural soil, and is beneficial to the vegetation growth and ecological restoration of the side slope.

Description

technical field [0001] The application relates to the field of expansive soil slope treatment and ecological slope protection, in particular to a cement-modified expansive soil, a preparation method thereof, and an ecological base material of the cement-modified expansive soil. Background technique [0002] Expansive soil is a kind of clay with expansion and contraction properties, many cracks and high plasticity. Expansive soils are widely distributed in my country, and projects such as high-speed railways, highways, and water delivery channels often pass through expansive soil areas. The special engineering characteristics of expansive soil are easy to damage the houses, roads, channels and other projects built in the distribution area, thereby damaging people's lives and property safety, and engineering circles often call it disastrous soil. The strength of expansive soil in the natural state is usually very high, but due to the complex and combined effects of its expans...
