Product Description

Driving Ground Rod SPT Sampler Standard Penetration Test Equipment  

SPT Drive Rods are manufactured to connect with the SPT Split Tube Sampler and comply with the BS 1377: Part 9: 1990.
The rod O.D. is 54 mm with solid 1-1/2" B.S. Whitworth male and female tool joints on each end. The tool joints are friction welding with the Rods and has a pair of spanner flats to facilitate handling.   


The rod weighs only 8.8 kg per meter but is both stronger and stiffer. It has four kinds of standard lengths, like 3.0m, 1.5m, 1.0m and 0.75m.   


The Automatic Trip Hammer comprises following parts:  


a) A weight made of steel and provided with an axial hole with a diameter which is 3 mm to 4 mm larger than that of the guide rod. It is of 63.5 kg.

b) A pick-up and release mechanism to ensure that the weight has a free fall of 760 mm and shall not influence the acceleration and deceleration of the weight or the rods.   

c) An inner guide shaft to permit the weight to drop with minimal resistance, and to ensure the weight strikes the anvil squarely.   

d) An anvil made of steel with an integral threaded portion to connect squarely and rigidly on to the top of the uppermost extension rod.
