Abstract

The invention relates to a fiber aid for slope spray-seeding greening, a preparation method and a matrix. The preparation method comprises the following steps: adding magnesium aluminum silicate or attapulgite into water at normal temperature, and fully swelling; adding a calcium chloride solution and fully mixing; adding a magnesium sulfate solution, fully mixing and reacting; adding a diammonium hydrogen phosphate solution, and adjusting the pH value to 6.5-7.5; and adding a sodium carboxymethyl cellulose solution, and uniformly stirring and mixing to form the fiber aid. By adding the fiber aid, the long-acting stability of the matrix material is improved, and the slope ecological protection effect is guaranteed. In addition, the addition of the fiber aid can optimize the proportion of the existing substrate, reduce the consumption of plant fibers on the basis of not influencing the anti-scouring performance of the substrate, and improve the technical economy of the spray-seeding technology.

Description

technical field [0001] The invention relates to the technical field of slope ecological protection matrix, in particular to a fiber aid for slope spraying greening, a preparation method and a matrix. Background technique [0002] The spraying ecological protection technology is widely used in the field of slope ecological protection due to its advantages of high construction efficiency and low cost. Due to the complexity of the soil composition and the differences in the natural environment, the matrix used in the slope ecological restoration process may degrade under the action of natural factors such as microorganisms and ultraviolet rays, making the construction effect unable to meet the ideal requirements. Especially on high and steep rock slopes and concrete slopes, it is difficult for the matrix material to adhere, and it is easy to delaminate, causing the whole piece to fall off. In addition, in order to improve the anti-scouring performance of matrix materials durin...
