Description

Undisturbed soil sampler

Technical Field

The utility model belongs to the technical field of soil sampler, and more particularly relates to an undisturbed soil sampler.

Background

The original form and structure of the original soil need to be ensured by the original soil on-site sampling, and disturbance cannot be generated. The common soil sampling drill is easy to lead the soil sample to be compact and deformed and the structure to be damaged; the traditional on-site undisturbed soil sampling is that the method of beating into soil frame with the hammer is sampled, the soil sample of taking out still needs the form stripping, can make the soil sample produce very big disturbance like this, the operation is complicated, work efficiency is low, be difficult to guarantee that the appearance of cylindricality undisturbed soil sample is complete, a lot of geotomes are carried out the soil sampling now, generally tubular structure inserts in the soil, take out the earth pillar and take out the sample, but the device is taken out the earth pillar after, usually need extrude from upper portion and make the earth pillar in the tubular structure extrude, then carry out follow-up research experiments etc. because earth pillar and inner wall friction, need use great power to extrude and just make the earth pillar fall, extrusion at this moment can destroy the undisturbed soil, extrusion makes its deformation.

The application number is that the soil sampler with the structure has the defect that the extrusion can damage the original shape of original soil and deform the original soil.

In view of this, we design a structure that can complete the sampling without damaging the earth column after soil sampling.
