Aqualock

AquaLock is a soil sampler, vibrated down directly to sampling depth for a 1,5 m long virtually undisturbed sample. It can be used for continuous or discrete sampling. Prior to drilling, the AquaLock is pressurized with water to lock the piston down in the cutting shoe. When the desired sampling depth is reached, water pressure is released via push rods. Drilling continues an additional 1,5 meter. Vacuum holds the sample in the tube while retrieved. Above ground water pressure is applied such that the piston pushes the soil out of the tube.
