Plate load test kit

Type

Determination of the bearing capacity of a soil

Plate Load test is usually used for the verification of the bearing capacity of the land of the substrate, of the foundation layer and the base layer of the flooring, although it is not uncommon to its use to investigate the bearing capacity of the soil surface or to the state compaction of granular materials and road surfaces

The test consists in transmitting to the soil to be tested and the subsequent increasing load increments, detecting simultaneously the sagging and therefore allows to directly determine a form of deformation or compressibility of the soil. The load transmission takes place via the application of a force by means of a hydraulic system of thrust, of a circular plate. The subsidence induced by the ground plate are simultaneously detected by centesimal or digital data acquisition systems, integral with a frame of reference outside the area of influence of the applied load. Of fundamental importance, in any case, is the use of the proper contrast medium whose mass is a function of the expected load. 

Standards: CNR BU 146, SN 670 317 and 670317th, the LCPC method CT2.

DESCRIPTION
Plate Load test is usually used for the verification of the bearing capacity of the land of the substrate, of the foundation layer and the base layer of the flooring, although it is not uncommon to its use to investigate the bearing capacity of the soil surface or to the state compaction of granular materials and road surfaces.

\
These tests are generally conducted with metal plates of standard diameter D=300/750 millimeters, could be carried out from ground level and inside the wells whose depth is limited only by the size of the jack and related extensions.
