A ground reinforcement grouting material

Abstract

The invention provides a grouting material for foundation reinforcement. Slurry is prepared by selecting Portland cement a main material and adding admixtures of sulfate aluminium cement, slag micropowder, coal ash, gypsum, lime, sodium silicate, calcium carbonate powder, calcium hydroxide, low-viscosity cellulose and the like; the original loose soil bodies or cracks are cemented and solidified to form a new consolidation body, so that the constituents, the seepage performance, the chemical stability, the mechanical property and the like of the soil body structure are changed, and higher engineer properties are achieved.

Description

technical field

[0001] The invention relates to a ground reinforcement grouting material. Background technique

[0002] Grouting, also known as grouting, uses pressure feeding equipment to inject a certain proportion of slurry-like solidified material into the soil layer or cracks by means of pressure, and spreads, gels and solidifies it to form new stones, which are used to reinforce the soil layer and prevent it. Seepage and plugging to meet the construction requirements of civil engineering projects.

[0003] Grouting technology has a history of more than 200 years, and its development has gone through four stages: (1802-1857) the development stage of the original clay slurry, (1858-1919) the primary cement slurry development stage, (1920-1969) Year) Intermediate chemical grout grouting development stage, (after 1969) modern grouting development stage. Grouting methods mainly include infiltration grouting, filling or crack grouting, splitting grouting, compaction grouti...
