Embodiment

[0046] According to the above steps 1 and 2, 26 groups of phosphogypsum-based vegetation concrete with the same amount were prepared, and 5 groups of control groups were prepared. The specific formulations of each group are shown in Table 1.

[0047] Each group concrete formula of table 1

[0051] 2. Select the grass species as ryegrass, and the grass content is 90g / m 2 After preparing the base phosphogypsum-based vegetation concrete slurry and the surface layer phosphogypsum-based vegetation concrete slurry, spray according to the method of step 3. Bind the straw on the barbed wire, the distance between adjacent straws is 30cm, and the width between the net and the net is 15cm. The average thickness of the base layer concrete is 7cm, and the average thickness of the surface layer concrete is 3cm.

[0052] 3. The construction time is from March to June, and the average outdoor temperature is 10-23°C. After one week of spraying, the compress...

Abstract

The present invention belongs to the technical field of water and soil protection, and particularly relates to phosphogypsum-based vegetation concrete and a construction method thereof. The specific technical solution is as follows: the phosphogypsum-based concrete comprises phosphogypsum, soil, rice husk ash, humic acid, a retarder, plant fibers, brucite fibers, a water retaining agent and water.A large amount of the phosphogypsum and rice husk ash are used; high bonding strength between the concrete and slopes is high; anti-pressure and anti-tensile abilities are strong; an anti-erosion ability is strong; the phosphogypsum-based vegetation concrete also provides nutrient elements required for growth of various surface layer grass seeds; the humic acid further helps quick ecological recovery; and long fibers and short fibers are also combined to improve the own performance of the concrete, help vegetation to grow rapidly and exist for more than ten years or even decades, continuouslystrengthen and toughen the concrete, and improve the crack resistance and durability of the concrete.

Description

technical field [0001] The invention belongs to the technical field of water and soil protection, and in particular relates to a phosphogypsum-based vegetation concrete and a construction method thereof. Background technique [0002] In recent years, during the construction of infrastructure projects such as water conservancy, electric power, highways, and railways, a large number of slopes are often excavated. The development of the slope destroyed the original vegetation cover, resulting in the exposure of a large number of rocks and land, resulting in a series of ecological environment imbalance problems, such as soil erosion, landslides, mudslides, deterioration of local microclimate and destruction of the biological chain, etc. . If the exposed slopes caused by these projects rely solely on natural forces, it will often take a long time to restore the ecological balance. Soil slopes can achieve ecological restoration in a short period of time through artificial protec...
