From the specified soil sampling depth, including the safety sampling device for perennial frozen rock

摘要

A useful model is a device for safely drilling soil,Including perennial permafrost,It can be used to safely take various soil samples in the field for laboratory research,For scientific purposes,And the evaluation of technical land.The technical result of the practical model is that the extraction and research of soil samples have high safety,And improve the quality of the final research results of the selected samples,Reduce the labor intensity of sampling,Universality and operability are achieved through the compactness and mobility of the declared useful modes.The device comprises a cylindrical drill bit tube,It has several through holes on both sides of the guide rail wall,Their centers are at a certain distance and coincide with the hole center on the opposite guide rail wall,A process plug is installed on the top of the pipe,There is a tool at the bottom,The drill pipe is immersed and removed from the soil through a hot block with a gas burner,Heat shield and ash collection.
