20140161540 | MEASURING UNDERGROUND PRESSURE - The present invention relates to in-place soil stabilization. Specifically, the present invention relates a method and device for measuring the increase in subsurface earth pressure during the injection of a stabilizing agent into the soil. The rise in sensor pressure indicates an increase in soil strength and bearing capacity. Therefore, real-time monitoring of these pressures may serve as a guide during the injection process. | 06-12-2014 |
20100272518 | METHOD AND DEVICE FOR PROTECTING EARTH INJECTED MATERIALS FROM CONTAMINANTS - The present invention provides methods and apparatus for soil stabilization. First, a void is formed in the compromised soil strata. Then, an expandable member containing expandable materials is placed into the void. As the material expands to fill the void, the surrounding soil is compressed. This in situ compression if the soil increases the load bearing capacity and compressive strength of the soil. Additionally, the present invention provides a method for isolating the injected materials from the environment at the injection and/or polymerization point. | 10-28-2010 |
