Penetrometer Design

Dph Penetrometer

1 P Dimensions and masses of the components of the driving device are given in table 6.1. The following requirements shall be fulfilled - the steel hammer must be conveniently guided to ensure minimal resistance during the drop - the automatic release mechanism shall ensure a constant free fall, with a negligible speed of the hammer when released and no induced parasitic movements in the drive rods - the steel drive head or anvil shall be rigidly connected to the top of the drive rods. 1 P The...

Dilatometer Probe Rod

1 P The vane shall consist of four rectangular plates fixed at 90 angles to each other, see figure 8.1. The blades shall be parallel with the extension rods and no distortion is allowed. 2 P The relation between the height h and the diameter o of the vane shall be 2,0 for standard vanes. 3 A maximum vane size cfx h of 100 mm x 200 mm for very soft soils and a minimum vane size of 40 mm x 80 mm for dense soils are commonly used for standard vanes. 4 P The blade thickness shall not exceed 3,0 mm...
