Embodiment 1

[0027] A method for synergistically improving the strength and long-term repair function of ecological slope protection substrates by using zeolite and biochar, which is made of the following materials: 100kg of planting soil, 8kg of cement, 6kg of organic materials, and 4kg of habitat substrate improvers.

[0028] During preparation, the planting soil, cement, organic materials, and habitat base material improver are mixed with dry materials in proportion to obtain a mixed material; then it is used for spraying construction and maintenance.

[0029] According to experiments, the pH value of the ecological slope protection base material prepared by this preparation method is 7.9, the nutrient retention coefficient is 46.8%, and the soluble organic carbon content is 12.32 mg / kg.

Embodiment 2

[0031] A method for synergistically improving the strength and long-term repair function of ecological slope protection substrates by using zeolite and biochar, which is made of the following materials: 100kg of planting soil, 8kg of cement, 6kg of organic materials, 4kg of habitat substrate improvers, and biochar 2kg, zeolite 1kg.

[0032] During preparation, the planting soil, cement, organic materials, and habitat substrate improvers are mixed uniformly with dry materials in proportion to obtain material 1; then material 1 is mixed and stirred evenly with biochar and zeolite to obtain a mixed material; and then used for Spray construction and maintenance.

[0033] According to experiments, the ecological slope protection base material prepared by this preparation method has a pH value of 8.9, a 26% increase in strength, a 41% increase in nutrient retention capacity, and a 23% increase in soluble organic carbon content.

Embodiment 3

[0035] A method for synergistically improving the strength and long-term repair function of ecological slope protection substrates by using zeolite and biochar, which is made of the following materials: 100kg of planting soil, 8kg of cement, 6kg of organic materials, 4kg of habitat substrate improvers, and biochar 2kg, zeolite 2kg.

[0036] During preparation, the planting soil, cement, organic materials, and habitat substrate improvers are mixed uniformly with dry materials in proportion to obtain material 1; then material 1 is mixed and stirred evenly with biochar and zeolite to obtain a mixed material; and then used for Spray construction and maintenance.

[0037] According to experiments, the pH value of the ecological slope protection substrate prepared by this preparation method is 8.5, the strength is increased by 35%, the nutrient retention capacity is increased by 47%, and the soluble organic carbon content is increased by 24%.

Abstract

The invention relates to a method for synergistically improving the strength and a long-acting repairing function of an ecological slope protection base material by using zeolite and biomass charcoal and is applied to the technical field of slope protection and ecological repairing. The method comprises the following steps: the ecological slope protection base material is prepared from planting soil, cement, an organic material and a habitat base material modifier according to a dry material mass ratio, and then the biomass charcoal and the zeolite are uniformly mixed in proportion, stirred into the ecological slope protection base material, and subjected to spraying and seeding on the side slope by using an air compressor. According to the method, the ecological slope protection base material has the advantages of more hydrated cement, higher strength, higher nutrient immobilization capability and more lasting ecological restoration function, and has remarkable practical significance in engineering application of the ecological slope protection base material.

Description

technical field [0001] The invention relates to the technical field of slope protection and ecological restoration, in particular to a method for synergistically improving the strength and long-term restoration function of ecological slope protection substrates by utilizing zeolite and biomass charcoal. Background technique [0002] With the rapid development of economic construction, my country's infrastructure construction is in full swing, road construction, hydropower project construction, mining, etc. will inevitably form many damaged slopes, and ecological protection technology has emerged as the times require. In our country, after decades of development, the sustainable development of the ecological environment has become a consensus, and the restoration of ecological functions of damaged slopes is becoming an important indicator of regional ecological quality evaluation. At present, the most widely used and most effective ecological protection technologies in my cou...
