Apageo Menard Pressuremeter
Country : France
A Pressuremeter test is an in -situ stress controlled loading test performed on the wall of a bore hole using a cylindrical probe which can expand radially.From the test r eadings (volume variation based on Controlled pressure), a stress strain curve can be obtained, in the case of plane deformation, which yields :
- The Ménard Pressuremeter modulus Em
- The creep pressure Pf
- The Menard limit pressure PL
Control Unit (C.U.) tubing and 3-cells probe to perform in situ Pressuremeter test in soils according to the ISO 22476-4 and ASTM D-4719-07 Standards.The borehole is drilled so as to minimize wall disturbance and keep acavity diameter compatible with the probe size.The probe is lowered into the borhole to the required test depthand the pressure is applied by equal increments. Pressure and volume readings are taken on the Control Unit.

The control unit
Equipped with devices to precisely regulate the pressure applied to the probe and to read its volume changes with pressure increments and time. A nitrogen cylinder provides the pressure source.
The plastic tubing
This coaxial or twin tubing, flexible, high resistance with small dilatation, connects the probe to the monitoring box.
The 3-cell probe
It includes a central measuring cell, filled with water. It volume changes are read on the Control Unit volumeter
