Description

Portable soil sampling equipment

Technical Field

The utility model relates to the field of geotechnical test equipment, in particular to portable soil sampling equipment.

Background

The ring knife method is the traditional method for measuring the field density. The volume of the cutting ring adopted by the domestic habit is usually 200cm3, and the height of the cutting ring is usually about 5 cm. The density measured by the ring cutter method is the average density of the soil sample in the ring cutter within the depth range. It does not represent the average density of the entire laminate. Since the density of the rolled soil layer generally decreases from top to bottom, if the cutting ring is disposed at the upper part of the rolled soil layer, the obtained value tends to be large, and if the cutting ring is disposed at the bottom part of the rolled soil layer, the obtained value tends to be significantly small, and in terms of checking the compaction degree of the roadbed soil and the pavement structure layer, we need the average compaction degree of the whole rolled soil layer rather than the compaction degree of a certain part of the rolled soil layer, and therefore, when the density of the soil is measured by the cutting ring method, the obtained density should represent the average density of the whole rolled soil layer. However, this is difficult in actual detection; the ring cutter method may produce results that are about the same as the sand-cast method only if the soil taken by the ring cutter is exactly the soil in the middle of the rolled layer. In addition, the ring cutter method has a narrow application range and cannot be used for stabilized soil containing granules and loose materials.

Traditional cutting ring method sample of getting soil, the use is loaded down with trivial details, and the instrument that needs is more, and sampling efficiency is lower, can not satisfy large-scale earthwork construction progress requirement, and the sampling process receives human factor's influence moreover great, influences the testing result in later stage.
