| Summary: | A Mackintosh probe is a lightweight portable penetrometer that is designed to be a tool to investigate the soil bearing capacity. The tool consist of high yield steel rods, each of length approximately 120cm that are connected each other by 25mm outer diameter couplings with a 27.9mm diameter of a 30o –apex angle; 12.7 mm diameter solid rods and a 4.5 kg dead weight with standard drop height of 300mm. The applications of the Mackintosh probe are by assembling the equipment, marked on each 0.3m on the rods, set up the equipment on the ground, pulled up the hammer until maximum height, dropped freely to driven the rod and cone into the soil, continued until the blow reach more than 400 blows per 0.3m penetration or the depth reached 15m. Under any circumstances of the soil conditions, the rate of driven must be from 15 to 30 blows per minute and the deviation from the vertical of the first extension rod shall not be greater than 2%. |
