Undisturbed sediment sampling and contrast imaging system

Abstract

The invention is applicable to the field of silt sediment sampling and provides an undisturbed sediment sampling and contrast imaging system. The system comprises a double-pipe silt collecting device, a slicing device, drilling equipment and a contrast imaging system, wherein the double-pipe silt collecting device is used for collecting a silt sediment sample; the slicing device is positioned inside the silt collecting device and is used for slicing the frozen silt sediment; the drilling equipment is used for drilling the silt collecting device to a set depth and controlling the slicing device to rotate and move downwards; the contrast imaging system is used for performing contrast imaging on the silt sediment slices. According to the system, the silt sediments in fan deltas or wet lands can be sampled, frozen, sliced and subjected to contrast imaging, and the functions of sampling, freezing, slicing and performing contrast imaging on the in-situ silt sediments can be realized in the silt sediment system. Compared with the traditional technology, the system has the advantages that intuitive silt sediment image data can be acquired, relatively complete, rich and accurate geological information can be reflected by the image data, and the system has the advantages that the disturbance on the geological information of the silt sediments is low, the system can be used for field research for a long time, and the like.

Description

technical field [0001] The invention belongs to the field of muddy sediment sampling, in particular to an undisturbed bottom mud sampling and imaging system. Background technique [0002] Extracting information about nature, environment and human activities from muddy sediments, studying regional environmental changes, and predicting future climate change cycles are new research methods emerging at the end of the last century in the world. Among them, the collection and radiography of muddy sediments are effective methods. Acquisition and imaging analysis of silt deposits includes acquisition, freezing, sectioning and imaging of silt deposits. [0003] At present, the collection of muddy sediments all adopts grabbing samplers or drilling samplers to obtain muddy sediments from rivers, lakes or wetlands. Freezing measures can be carried out after removing the muddy sediment, and the muddy sediment can also be frozen in the sampler. The sections of sectioning and radiograph...
