Abstract
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.
