Abstract

The invention discloses a soil sample stratified sampling device and method, and relates to the technical field of soil analysis, a sampling rod is connected with a handle, and a longitudinal through hole is formed in the sampling rod; a first through hole penetrates through the first fixing piece and the handle, and a second through hole penetrates through the second fixing piece and the handle; a transverse through hole is further formed in the sampling rod, a scraper mounting ring sleeves the periphery of the sampling rod, a scraper is mounted on the scraper mounting ring, and one end of the first scraper control line is connected with the scraper; one end of the second scraper control line is connected with the scraper; the sampling container is arranged on the periphery of the sampling rod in a sleeving mode and located below the scraper, and the anti-deflection ring assembly is connected to the outer side of the sampling rod in a threaded and sleeving mode. By arranging the sampling rod, the transverse and longitudinal through holes, the scraper mounting ring and other structures, the device has the advantages of high sampling precision, high efficiency, convenience in operation and transportation, no damage to the original soil layer structure, energy conservation and emission reduction, and can solve the technical problems of inconvenience in shallow soil stratified sampling operation and related technical problems in the existing soil sampling method.

Description

technical field [0001] The invention relates to the technical field of soil analysis, in particular to a soil sample stratified sampling device and method. Background technique [0002] With the wider application of geological engineering exploration, there are more and more corresponding exploration methods, such as soil sampling, near-surface hydrological observation, shallow ground temperature measurement, water supply and drainage pipeline layout, power communication and municipal engineering layout survey, etc. . Field geological soil samples are used for many purposes, for example, to study soil layer distribution, soil layer thickness, soil layer moisture content, soil density, soil layer temperature, hydrological status and material composition, etc., so to find out the physical and chemical properties of soil in underground soil layers seems particularly urgent. In order to accurately grasp the distribution of shallow soil, effectively develop, utilize and analyze...
