The Application of Pressure Grouting Technology in Foundation Treatment of Clarifiers

Abstract:

Basing on diffusion radius formula of pressure grouting which was deduced by the Darcy's law in groundwater dynamics and connecting with engineering example, this article introduces the construction parameters and analyzes results of pressure grouting. Several methods including Re-grouting, coring method and SPT were used in the effect detection, it turns out that the slurry owns a consolidation and filling effect around the grouting holes when it is injected into soil. This effect can reduce the porosity and moisture content of soil, then the foundation bearing capacity is improved and the settlement can be reduced. Practice has proved the feasibility of pressure grouting in repairing soft foundation of important buildings, so it is a valuable reference to foundation reinforcement under similar conditions.
