Problems solved by technology

The outer edge of the solidified polyurethane slurry will hinder the diffusion of the internal uncured slurry, so it is impossible to get an accurate displacement diffusion limit
In addition, the viscosity of polyurethane slurry cannot be adjusted in a wide range, and the test cannot obtain the influence of slurry viscosity on displacement diffusion

Embodiment 1

[0022] The high-viscosity anti-dispersion grouting material is prepared from polyacrylamide base material, water and dyeing agent. The mass ratio range of polyacrylamide base material to water is 1:30, and the mass ratio of dyeing agent to water is 1:100. The dyeing agent is made by mixing polyacrylamide solution and poinsettia solution at a mass ratio of 1:1 and then drying; the mass ratio of polyacrylamide and water in the polyacrylamide solution is 1:8; the mass ratio of poinsettia and water in the poinsettia solution is 1:2. (Poinsettia is actually acid fuchsin, molecular weight: 566.48)

[0023] Preparation method: first mix polyacrylamide and dyeing agent evenly, then sprinkle the mixed material into water evenly while stirring, let stand for 5-10 minutes to fully dissolve the base material, and re-stir evenly to complete the preparation of the slurry.

[0024] During the slurry preparation process, the materials must be evenly sprinkled while stirring to avoid the form...

Abstract

The invention relates to a high-viscosity dispersion-resistant grouting material, which is prepared from a polyacrylamide substrate, water and a dyeing agent, wherein the mass ratio of the polyacrylamide substrate to the water is 1:(30-500); the mass ratio of the dyeing agent to the water is 1:(100-300); and the dyeing agent is prepared by mixing a polyacrylamide solution with a poinsettia solution in the mass ratio of 1:1 and drying. The high-viscosity dispersion-resistant grouting material has the advantages of large viscosity adjusting range, small change of density, high dispersion resistance, high grouting property, easiness for cleaning and the like, is mainly applied to indoor grouting experiments, and is taken as substitute serous fluid for researching the displacement diffusion mechanism of serous fluid in flowing water.

Description

Technical field: [0001] The invention relates to a high-viscosity anti-dispersion grouting material, which is mainly used for indoor research on the theory of grout displacement and diffusion. Background technique: [0002] At present, the development of grouting theory is seriously behind the grouting technology. The existing grouting theory is difficult to play an effective guiding role in the treatment of water inrush grouting under complex conditions. The theory of hydrodynamic grouting, especially the theory of grout displacement and diffusion is insufficient, and more in-depth research is needed. [0003] The process of grouting is also the displacement of groundwater by grout. At present, most of the researches on the displacement and diffusion theory of dynamic water grouting adopt the method of field test. There are two types of grouting materials, one is easily soluble in water, such as acrylate and water glass; the other is insoluble in water, such as epoxy res...
