METHOD FOR CONSOLIDATING FOUNDATION SOILS OR FOR LIFTING VERY HEAVY OR VERY LARGE STRUCTURES REQUIRING THE APPLICATION OF A PRESSURE OF MORE THAN 500 kPa

摘要

A method for consolidating foundation soils or for lifting very heavy or very large structures requiring the application of a pressure of more than 500 kPa, which consists in injecting into the soil to be consolidated or into the soil below the foundations of the structure to be lifted substances which expand as a consequence of a chemical reaction and are suitable to generate, during expansion, a pressure of more than 500 kPa.
