PDA Testing will provide prediction on the pile bearing capacity, pile integrity, driving stresses and hammer performance for a given pile penetration. It is a relative low cost type of pile testing compared to static load test (MLT or CRP). The testing technique is quick and accurate.PDA also can be used to perform high strain pile bearing monitoring to evaluate pile driving information for pile bearing capacity, pile integrity, driving stresses and transferred energy against pile penetration. The results are essential for the actual pile driving process and to obtain valuable data on the hammer, pile & soil system for re-design on the piled foundation(if necessary).

Automatic Coarse Soil Rock Sand Direct Shear And Triaxial Test Apparatus This product is used to test and analyze the stress-strain relationship, deformation and strength characteristics of coarse grained soil under triaxial unequal stress conditions, and to study the numbering rule of deviatoric stress, volumetric strain and internal friction angle with S2 coefficient of intermediate principal stress. Because the conventional triaxial only considers the stress in S1 and S3 directions, and does not consider the influence of the intermediate principal stress, it cannot truly reflect the stress characteristics of the soil mass. In order to obtain the actual stress state of coarse-grained soil in the project, only through the true triaxial testing machine can the triaxial unequal stress be applied to the coarse-grained soil sample, and the actual stress characteristics of the land can be truly and accurately reflected.

Standard: EN 1097-2, Also conforming to NF P18-573, UNE 83 114, UNI 8520-19, CNR No. 34, ASTM C131 Los angeles abration machine consists of a rolled steel drum having an inside diameter of 710 mm and internal length 510 mm. The drum is rotated by a speed reducer driven by an electric motor at a speed of between 30 and 33 r.p.m. The machine is equipped with an automatic counter, which can be preset to the required number of revolutions of the drum. The unit is supplied with the abrasive charge.
