U100 sampling systems for Geotechnical Site Investigation and Soil Sampling

U100 sampling systems

This equipment is designed for taking samples in clay and other soft formations. The sample tubes are each 18″ long and are driven into the ground using a sliding hammer with U100 drive head (bell housing) attached. The drive head contains a ball valve to allow air to be released from the upper part of the sample tube as it is being driven into the ground.

Product Description

This equipment is designed for taking samples in clay and other soft formations. The sample tubes are each 18″ long and are driven into the ground using a sliding hammer with U100 drive head (bell housing) attached. The drive head contains a ball valve to allow air to be released from the upper part of the sample tube as it is being driven into the ground.

Two types of sampling systems are currently manufactured:

Standard system
Consists of aluminium or cadmium-plated steel sample tubes, an optional corecatcher and a case-hardened drive shoe. The drive shoes can be supplied with either a plain or serrated edge. Plastic push-on caps or screw-on aluminium caps can be provided for the sample tubes and a special sealing wax for long-term storage.

Plastic liner system
Consists of a steel body tube, containing a removable plastic liner, an optional core- catcher, a spacing ring (used only with the corecatcher) and a case-hardened drive shoe. Plastic push-on caps are supplied for the plastic liners.
