Problems solved by technology

The viscosity of acrylamide grouting material grout is similar to that of water. The grout can fill the water seepage parts below 0.1mm in the structural cracks. The grouting performance is far better than all current grouting materials, but the acrylamide monomer is toxic, thus limiting the scope of use of this material

Abstract

The invention relates to an organic / inorganic composition for consolidating quicksand and a preparation method thereof. The organic / inorganic composition comprises the following components: a component A, which comprises hydroxyethyl acrylate, acrylamide, N,N-methylene bisacrylamide, triethanolamine, glycerol triacetate and water; and a component B, which comprises water glass, an initiator, water and an emulsifier. The preparation method comprises the following steps: preparation of a composition A: dissolving acrylamide and N,N-methylene bisacrylamide into water, adding hydroxyethyl acrylate, triethanolamine and glycerol triacetate into the water after acrylamide and N,N-methylene bisacrylamide are completely dissolved, and uniformly stirring to obtain the composition A; preparation of the composition B: dissolving an initiator and an emulsifier in water to form a mixture dissolving solution, and adding the mixture dissolving solution into water glass to obtain the composition B; and mixing the composition A and the composition B through a grouting machine at the temperature of 10-25 DEG C and then injecting into quicksand. The mixture solution is forcibly diffused, permeated, reacted and solidified, and then the quicksand can be consolidated. The composition is nontoxic or is low in toxicity.

Description

technical field [0001] The invention belongs to the technical field of composite grouting materials, and in particular relates to an organic / inorganic composition for consolidating quicksand and a preparation method thereof. [0002] technical background [0003] Chemical grouting and sand fixation is to prepare a certain chemical material (inorganic or organic material) into a solution, and use a chemical grouting pump and other pressure-feeding equipment to pour it into the formation or gap to make it diffuse, gel or solidify, so as to increase the strength of the formation, It is a ground treatment and concrete building crack repairing technology to reduce the permeability of the ground and prevent the deformation of the ground. [0004] Chemical grouting and sand-fixing materials are widely used in infrastructure construction. It is mainly divided into inorganic grouting materials and organic grouting materials. Inorganic grouting materials are mainly cement and water g...
