Slope protection and greening material and preparing and application method thereof

Abstract

The invention discloses a slope protection and greening material and a preparing and application method thereof. The slope protection and greening material is prepared from 35-45% of sludge, 30-40% ofstone powder, 5-15% of attapulgite powder, 5-10% of lignosulfonate, 5-10% of pregelatinized starch, 2-5% of potassium polyacrylate, 1-5% of polyvinyl alcohol and 0.1-0.5% of plant seeds, and raw materials are uniformly mixed and stirred into a pasty finished product. By means of the slope protection and greening material, on one hand, urbane sludge can be digested, on the other hand, rich organicmatter and mineral elements are provided for the growth of slope protection landscape grass. The added stone powder, the attapulgite powder, lignosulfonate, the pregelatinized starch, potassium polyacrylate and polyvinyl alcohol achieve the functions of improving the structure of the material, improving the viscosity of the material, retaining water and the like respectively; the added plant seeds are matched according to the construction site spontaneous growth advantage community structure, so that final plants are reasonable in ecological structure.

Description

technical field [0001] The invention belongs to the field of environmental resources, and in particular relates to a slope protection greening material and a preparation and application method thereof. Background technique [0002] Traditional slope engineering reinforcement measures include dry rubble, concrete blocks, anchoring slope protection and sprayed soil and other projects. These measures are costly and damage the natural ecological environment. With the enhancement of people's awareness of ecological environment, ecological slope protection technology has begun to be applied to engineering construction. The commonly used ecological slope protection technology is artificial grass slope protection, that is, the traditional slope plant protection measures of sowing grass seeds on the slope surface. However, the artificial grass slope protection technology is only suitable for slopes with low slope height and small slope suitable for grass growth, and grass seeds are...
