DAMES AND MOORE SAMPLER

Introduction:

• Highly useful for sampling soils.
• The sample collects into rings inside the sampler.
• These rings along with the specimen can be directly placed in a consolidometer cell assembly, thereby reducing the number of operations to extract the sample from a sampler, trimming to size and transferring into the ring etc.
• The possible disturbance in these operations is eliminated.

General Description and Specifications:

• The area ratio for this sampler is 81 percent and it meets with the specifications of sub-surface Exploration and Sampling of Soils for Civil Engineering Purposes by M.J. Hvorslev.
• Consists of a split tube accommodating ten thing brass rings 60 mm x 25.4 mm long.
• A shoe with hardened cutting edge is screwed at one end.
• A driving head with ball check valve is fitted at the other end.
• The flaps mounted inside the cutting shoe prevent the cohesion less soil falling down while lifting the sampler.

Spares: Body consisting of split pipe threaded at both the ends and shoe.

Head Assembly: Set of 10 rings 60 mm O.D. and 25.4 mm long.
