Measuring underground pressure

摘要

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.

主权项

1. A method for stabilizing soil comprising:
drilling at least one injection hole to at least one injection site located in in situ soil to be stabilized; drilling at least one monitoring hole in the in situ soil to be stabilized; placing, through the at least one monitoring hole, a pressure monitoring device in the in situ soil to be stabilized; injecting into the at least one injection site a soil stabilization agent; receiving, through the soil located between the pressure monitoring device and the at least one injection site, a measurement of the pressure of the soil as the soil stabilization agent is being injected; and terminating injection of the soil stabilization agent when the pressure monitoring device indicates the soil has exceeded a predetermined pressure.
