PY-6 Field Pressuremeter For Soil Testing--ASTMD4719
PY Field Pressuremeter For Soil Testing


Test Description:
A pressuremeter test is an in-situ stress controlled loading test performed on the wall of a borehole using a cylindrical probe which can expand radially.

For the test readings (volume variation based on controlled pressure), a stress-strain curve can be obtained, in the case of plane deformation, which yields:
-the Menard pressuremeter modulus
-the creep pressure
-the Menard limit pressure

Test procedure
The borehole is drilled so as to minimize wall disturbance and keep a cavity diameter compatible with the probe size.
The probe is lowered into the borehole to the required test depth and the pressure is applied by equal increments.
Pressure and volume readings are taken on the Control Unit.
In gravely soils and/or under water table level where the borehole would cave-in, the probe can be inserted in a specially designed slotted tube which is hammered or ibrodriven into the soil.
Used without acquisition, the C.U. meets the requirements of the EN ISO 22476-4 standard part A.
