Foundations that can directly bear the load of a building without being treated are called natural foundations, whereas foundations that are treated by a foundation treatment technique are called artificial foundations. And determining the use site of the construction project according to the land property and the use right. Grouting is the process of pouring some solidified materials, such as cement, lime or other chemical materials, into the ground rock and soil within a certain range under the foundation to fill cracks and pores in the rock and soil, prevent the leakage of the foundation and improve the integrity, strength and rigidity of the rock and soil. In water-retaining buildings such as gates, dams, dikes and the like, a foundation impervious curtain is constructed by a grouting method, which is a main foundation treatment measure of hydraulic buildings. The grouting is that slurry with fluidity and gelling property is pressed into the stratum or the gap of the building according to a certain proportion requirement to be cemented and hardened into a whole through drilling (or embedding pipes), thereby achieving the engineering purposes of seepage prevention, consolidation and reinforcement. Grouting can be divided into curtain grouting, consolidation grouting, backfill grouting, contact grouting, joint grouting, reinforcement grouting, crack grouting and the like according to the functions of the grouting; the grouting material can be classified into cement grouting, clay grouting, asphalt grouting, chemical material grouting, and the like.
