Abstract
The utility model discloses a shallow undisturbed soil sampler. The shallow undisturbed soil sampler comprises an upper sleeve (1), a lower sleeve (2) and a pressing device (3), wherein the upper sleeve and the lower sleeve are both hollow cylinders; a plurality of rectangular grooves I (6) are formed between inner and outer arms of the upper sleeve; a plurality of rectangular grooves II (10) having the same number with that of the rectangular grooves I (6) of the upper sleeve and corresponding to the rectangular grooves I (6) of the upper sleeve are formed between inner and outer arms of the lower sleeve; a plurality of grooves (11) having the same number with that of the rectangular grooves II (10) and communicated with the rectangular grooves II (10) are formed between inner and outer arms of the bottom of the lower sleeve; the upper sleeve and the lower sleeve are in threaded connection; the pressing device adopts a flat long metal rod; the top of the metal rod takes the flat shape; the middle part of the metal rod takes the slender flat rod shape; the bottom of the metal rod takes the bent hook type iron sheet shape; and the pressing device is mounted in the rectangular grooves I, the rectangular grooves II and the grooves. The soil sampler is adopted to sample soil with simple soil sampling method and accurate test results.
Description
technical field:
The utility model relates to a kind of soil sample barrel, specifically the shallow soil soil sample barrel of a kind of soil test undisturbed soil sample used.
background technology:
Along with developing rapidly of national economy, civil engineering work industry is constantly progressive, and along with the increase of its scale, the problem relating to is also more and more, and the undisturbed soil collection before geotechnological shop experiment is exactly one of them.Mostly the collection of traditional soil test shallow-layer soil sample is, after the soil sample gathering by boring is taken laboratory to, the soil pressure of required soil layer is entered to cutting ring, in this process, not only surface soil layer has been caused to very large disturbance, and because soil is pressed into cutting ring again, lose the implication of undisturbed soil, cannot reach actual Expected Results by test.Therefore the soil sample barrel of, inventing a kind of shallow surface soil has actual meaning.
summary of the invention:
The purpose of this utility model is to provide a kind of shallow-layer undisturbed soil soil sample barrel, and to solve that current shallow-layer fetches earth and the soil layer perturbed problem that produces adopts this soil sample soil sample barrel to fetch earth, soil basketing method is simple, and test findings is accurate.
For realizing above-mentioned purpose of the present utility model, the technical scheme adopting is: a kind of shallow-layer undisturbed soil soil sample barrel, it is characterized in that containing upper sleeve, lower sleeve portion and hold-down devices, described upper sleeve and lower sleeve portion are all a hollow cylinder, between the cylinder inner arm of upper sleeve and cylinder outer arm, be provided with several rectangular slot I, between the cylinder inner arm of lower sleeve portion and tin outer arm, being also provided with several equates and corresponding rectangular slot II with the rectangular slot I quantity of upper sleeve, between lower sleeve portion bottom cylinder inner arm and cylinder outer arm, be also provided with several equal with rectangular slot II quantity and communicate grooves, upper sleeve and lower sleeve portion are threaded togather, described hold-down devices is the Metallic rod of a prolate, the top of Metallic rod is flat, middle part is elongated flat bar shape, bottom is crooked hook-type iron plate shape, hold-down devices is installed on rectangular slot I, in rectangular slot II and groove.
Described upper sleeve and the internal diameter of lower sleeve portion are more bigger with cutting ring external diameter than soil test.
Described lower sleeve portion and soil test are close with cutting ring height.
Using method of the present utility model is: first test is inserted in the lower sleeve portion of shallow-layer undisturbed soil sample soil sample barrel with cutting ring, determine the shallow-layer soil sample that will get, by ground surface soil local excavation to required soil layer, then the shallow-layer undisturbed soil sampling device with cutting ring is pressed into stratum, when compression distance is during a little more than the height of cutting ring, press sleeve Metallic rod around, Metallic rod bottom is separated with its underpart soil layer by the soil of lower sleeve portion bottom by the iron plate by transverse shifting, again soil sample barrel is brought up, detachable lower sleeve portion is disassembled, then take off cutting ring.This shows, the state when soil in cutting ring is keeping fetching earth always, and can not produce disturbance, and adopt soil sample barrel of the present utility model to fetch earth, soil basketing method is simple, and test findings is accurate, is worthy of popularization.
