Menard pressuremeter MPM test instrument

 

The Menard pressuremeter is used to execute Pressuremeter (MPM) Test in in-situ investigation, it can be used for testing of Cohesive soil, silty soil, sandy soil, strongly weathered rock, soft rock.

The pressure test is to place a cylindrical pressure bystander into soil vertically, use the expansion of the pressure bystander to apply uniform pressure to the surrounding soil, thus measure the relationship between radial pressure and deformation, and then obtain the stress-strain relationship in the horizontal direction of foundation soil. The pressuremeter is divided into three types: pre-drilling type, self-drilling type and press-in type.
