Problems solved by technology

[0008] However, in a large number of actual projects, it is also found that the vegetation concrete slope protection greening technology has some shortcomings. The main problem is that the greening base material is added with cement. After the cement is hydrated, the calcium hydroxide produced leads to a high early pH value of the base material. , greening base material compaction is not conducive to the activities of microorganisms i...

Embodiment 1

[0026] Embodiment 1: a kind of preparation method of improved vegetation concrete greening additive,

[0027] (1) Preparation of sulfur-rich bacterial powder A:

[0028] The sulfur bacteria are put into the sucrose solution for cultivation, and the powder A rich in sulfur bacteria is obtained after dehydration treatment; the addition amount of the sulfur bacteria and the sucrose solution is 1 part by weight of the sulfur bacteria, and 800-1200 parts of the sucrose solution, The concentration of sucrose solution was 2%. When the sulfur bacteria are cultured in the sucrose solution, the pH value of the solution is controlled to be 2-3, and the culture time is 24 hours.

[0029] (2) Preparation of mixture B:

[0030] In parts by weight, 10-18 parts of iron ore powder, 20-30 parts of calcium powder, 30-40 parts of phosphate rock powder, 10-20 parts of silicon ore powder, 2-3 parts of powder A rich in sulfur bacteria, 2 parts of sulfur powder -3 parts, 30-50 parts of compo...

Abstract

The invention discloses a preparation method of an improved greening additive for vegetation growing concrete. The additive is prepared by processing iron ore powder, calcium powder, phosphate ore powder, silicious ore powder, a compound fertilizer, a water-retaining agent, sulphur powder, an air entraining agent and sulphur bacteria. The improved greening additive is added into a vegetation growing concrete base material, so that the porosity of the vegetation growing concrete base material can be greatly increased, the pH value of the vegetation growing concrete base material can be reduced, a slope protecting greening base material of the vegetation growing concrete can be activated, and the process of recovering vegetation of a side slope can be speeded up.

Description

technical field [0001] The invention relates to the technical field of slope greening or slope ecological slope protection, in particular to a method for preparing an improved vegetation concrete greening additive capable of activating a vegetation concrete slope protection greening base material. Background technique [0002] Vegetation concrete slope protection and greening technology is to mix cement, loam, organic matter, plant seeds, fertilizers and vegetation concrete additives in an appropriate proportion to obtain vegetation concrete slope protection greening substrate (referred to as greening substrate, the same below), and then spray it with a concrete dry sprayer On the slopes that need to be greened, then the slope protection greening technology of sprinkling maintenance. On some slopes, anchor rods and hanging nets are often constructed before spraying to enhance integrity and stability. Since the technology came out around 2000, it has been popularized and app...
