Abstract
The utility model relates to a soil sampler used for soil drilling and sampling and particularly relates to a soil sampler which can obtain undisturbed soil samples. The soil sampler comprises a handle and is characterized in that a soil sampling tube is fixedly connected with the handle, the lower part of the soil sampling tube is provided with a semi-closed tube, a semi-closed cover is connected with the semi-closed tube through a hinge, open ends of the semi-closed tube and the semi-closed cover are provided with buckles for fixing, and the length of the semi-closed tube is 1/2 to 1/3 of that of the whole soil sampling tube. When the soil sampler is used, the buckles arranged at the open ends of the semi-closed tube and the semi-closed tube are fixed, the handle is tightly held to insert the soil sampler into soil, then soil sampling is conducted along with soil, the buckles on the semi-closed tube are slowly opened to expose the soil, and soil samples are cut by using a cutter to obtain the intact undisturbed soil samples. The soil sampler has the advantages of being simple in structure, simple and convenient in operation, labor-saving, high in undisturbed degree of the obtained soil samples, and small in disturbance of the soil samples.
Description
Technical field
The utility model relates to a kind of soil sample barrel that soil drills through sampling that is used for, especially a kind of soil sample barrel of taking undisturbed soil sample.
Background technology
The undisturbed soil sampling is an element task in engineering geological investigation, environmental engineering, agricultural engineering, the Hydraulic and Hydro-Power Engineering.Undisturbed soil is meant the natural structure of taking should keep in the process style in soil sample, and promptly the physical property of soil sample, mechanical property, chemical property etc. all remain unchanged in sampling process.If the natural structure of sample is damaged, just be called " disturbance appearance ".The disturbance of soil sample is not allowed maybe and should be avoided as far as possible in some engineering geologic investigations, the medium many fields of experimental study.
Soil sample barrel is claimed soil sample collector again, is that structure, composition and the content thereof of the soil sample of a certain degree of depth of soil that collects through analysis is studied corresponding soil layer soil physical, mechanical property, chemical property etc.Be widely used in industries such as engineering geological investigation, environmental engineering, agricultural engineering, Hydraulic and Hydro-Power Engineering.The structure of soil sample barrel and type are influence one of the principal elements of quality that fetches earth, so in the design of soil sample barrel, manufacture process, be to make institute's soil sampling not receive or receive less disturbance as far as possible to the basic demand of soil sample barrel; Can successfully cut in the soil layer and take out soil sample; Simple in structure, easy to use.
Original state sampling method commonly used has core cutter method and the original state pipe method that fetches earth.Core cutter method fetches earth to be needed to excavate the section hole earlier, exists shortcomings such as complicated operation, labour intensity is big, soil extracting efficiency is low; Tiretube process once can be obtained the soil sample of a plurality of soil layers though original state fetches earth, and soil extracting efficiency is higher, exists shortcomings such as the soil sample release is difficult, soil sample is separated precision ground, error is big.Therefore; The problem that exists to present soil basketing method anatomizes the whole process of soil sample barrel work, analyzes and fetches earth, cuts have which disturbance in each link such as soil, sampling; How to reduce disturbance to greatest extent, keeping the original state property of soil sample is most critical.
Summary of the invention
The utility model ground purpose is to provide a kind of simple in structure, easy and simple to handle, laborsaving, institute soil sampling original state degree high, the little soil sample barrel of soil sample disturbance.
The utility model discloses a kind of soil sample barrel, comprise handle, it is characterized in that being fixedly connected with the pipe that fetches earth with handle, the pipe bottom of fetching earth is provided with the pipe that narrows, and with the pipe lid that narrows that has been connected through the hinge that narrows, narrows and manages and the cover gab end that narrows is provided with snap fit.
The said length that narrows pipe is one of whole Guan Erfen of fetching earth between 1/3rd.
During use, the pipe that will narrow is good with the snap fit that the tube opening end that fetches earth is provided with, the handle of holding with a firm grip,, soil sample barrel is inserted in the soil, fetch earth together with soil then, slowly open the buckle on the pipe that narrows, soil exposes, and cuts soil sample with cutter, obtains intact undisturbed soil sample.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Embodiment
As shown in Figure 1; This soil sample barrel comprises handle 1, and handle 1 is fixedly connected with the pipe 2 that fetches earth; Fetch earth the pipe 2 bottoms be provided with narrow the pipe 6; Be connected with to narrow through hinge 5 with the pipe 6 that narrows and cover 3, the pipe 6 that narrows cover 3 openends to be provided with buckle 4 fixing with narrowing, said narrow manage 3 length be whole fetch earth manage 2 1/3rd.
During use, the pipe 6 that will narrow covers the buckle 4 that 3 openends are provided with and fixes the handle 1 of holding with a firm grip with narrowing; Soil sample barrel is inserted in the soil, fetch earth together with soil then, slowly opening narrows covers the buckle 4 on 3; Soil exposes, and cuts soil sample with cutter, obtains intact undisturbed soil sample.
Claims (2)
1. a soil sample barrel comprises handle, it is characterized in that being fixedly connected with the pipe that fetches earth with handle, and the pipe bottom of fetching earth is provided with the pipe that narrows, and with the pipe lid that narrows that has been connected through the hinge that narrows, narrows and manages and the cover gab end that narrows is provided with snap fit.
2. soil sample barrel according to claim 1 is characterized in that the said length that narrows pipe is one of whole Guan Erfen of fetching earth between 1/3rd.
