Abstract

The invention discloses a dual-purpose microstructure frozen heating sampler and a cutting device which is composed of a sampler and a cutting device, wherein the sampler and the cutting device are used alone. According to the device disclosed by the invention, soil layers of different states and types can be sampled, different equipment does not need to be replaced, expenditure is saved, disturbance of a soil sample in a flow condition is small, and sampling un-disturbance is ensured; the device disclosed by the invention realizes frozen sampler type sampling and sample preparation integration, comprises a heating device and a cutting device, reduces the manual operation and is labor-saving and high in safety; and the sampler disclosed by the invention is simple in structure and convenient to carry and is applicable to laboratory simulation test and field sampling.

Description

technical field [0001] The invention relates to the field of a sampler, in particular to a dual-purpose microstructure freezing and heating sampler and a cutting device. Background technique [0002] In the projects of land reclamation from the sea, improvement and dredging of rivers and waterways, the problem of self-weight consolidation of the dredged fill soil in a flowing state and a flow-plastic state will be encountered. The newly filled dredged fill has high moisture content, high plasticity index, large void ratio, low gravity and low permeability coefficient, and its consolidation process is particularly long. In order to speed up the consolidation speed of dredger fill, various consolidation methods such as vacuum preloading method and heap loading method have emerged as the times require. In order to study its consolidation characteristics, reduce the consolidation time of dredger fill, and increase economic benefits, many scholars have studied the self-weight co...
