  • Method and device for measuring pressure exerted by earth material
    Patent number: 10060249
    Abstract: A method for measuring pressure exerted by earth material includes: providing a pipe with a longitudinal bore defining an inner diameter, providing a device with sensors to sense said inner diameter, wherein the device is to be moved within the pipe along the longitudinal bore, while a measurement of the inner diameter is taken in a first transversal direction at one longitudinal position of the pipe. Then a measurement of the inner diameter in a second transversal direction at the predetermined longitudinal position is taken, wherein the second transversal direction is oriented differently to the first transversal direction. Finally, an ovalization of the pipe is derived at that predetermined longitudinal position of the pipe through subtracting a diameter value of the first transversal direction from a diameter value of the second transversal direction.
