Abstract

The invention discloses a soil solidification complexing agent based on a synergistic effect of biological enzyme and microorganisms as well as a preparation method and application of the soil solidification complexing agent, and belongs to the technical field of microorganism soil solidification. The preparation method comprises the following steps: dissolving levodopa in purified water, adding a carboxylic acid activating agent, and mixing and activating for 20-30 minutes to obtain an activating solution; mixing the activating solution with biological enzyme, reacting for 5-7 hours in an environment with the temperature of 20 + / -2 DEG C, and dialyzing to obtain dialysate; mixing and stirring the dialysate and a microbial bacterial solution to obtain a mixed solution, adjusting the pH value of the mixed solution to 8.0 by using a weak base solution, and cross-linking for 14-18 hours in an environment at the temperature of 20-25 DEG C to obtain a weak cross-linked solution; adjusting the pH value of the cross-linking solution to be neutral by using a weak acid solution, adding a calcium salt solution, mixing, stirring and standing for 12-15 hours to obtain the soil composite curing agent. According to the invention, a cross-linked network structure is constructed by using levodopa, so that the protection on biological enzymes and microorganisms is realized, and the soil solidification capability of the levodopa is improved.
