Description
Technical field
The utility model relates to a kind of soil sample barrel, especially a kind of opposite opened cutting ring soil sample barrel.
Background technology
Laboratory soil test is an existing Geotechnical Engineering test method commonly used when estimating, and main pilot project comprises permeability test, consolidation test, the test of shear test collapsibility of loess etc.Purpose is to obtain all kinds of physical mechanical property index of foundation soil, in order to engineering propertiess such as the intensity of estimating foundation soil, distortion, for the designer provides necessary design parameter.
The soil sample preparation process that test is adopted: be drilled in the predetermined depth soil layer with drilling tools, adopt common soil sample barrel to take a big soil sample.Then soil sample is transported to the laboratory.The cutting ring cutting edge is to being placed down in vertical depression on the soil sample, and with cutting native cutter along cutting ring outside cutting soil sample, transformation becomes to cut to the soil sample upper end and exceeds cutting ring, then with fret-saw or cut native cutter and along the cutting ring downside soil sample is cut off, and leveling cutting ring two ends soil sample, finish the preparation work of a soil sample.At last cutting ring and inner soil sample thereof are put into and carry out corresponding experiment work on the test apparatus.
Existing problems: relatively poor with the soil sample sealing that common soil sample barrel is taked, the natural aqueous rate of soil sample, natural density etc. there are considerable influence; In the virgin state of soil sample that has been transported to testing laboratory's process vibration influence, make the sample data distortion; In the laboratory preparation during test sample operation numerous and diverse and success ratio is lower, caused great waste in expense with on the duration.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple structure, easy to use, good airproof performance, success of the test rate height, opposite opened cutting ring soil sample barrel that expense is low are provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of opposite opened cutting ring soil sample barrel, comprise the soil sample barrel of forming by two opposite opened semicanals, the soil sample barrel upper end links to each other with the soil sample barrel head, fixedly connected with connector in soil sample barrel head upper end, the soil sample barrel lower end is connected with shoe, some annular undercuts are set on the soil sample barrel inwall, are provided with cutting ring in the undercut, the soil sample barrel head is provided with some openings.
Described soil sample barrel upper end links to each other with the soil sample barrel head by screw thread.
Described soil sample barrel lower end links to each other with shoe by screw thread.
The outside, described shoe lower end is the uniclinal declivous cutting edge.
The utility model utilizes existing general drilling equipment to carry out work.Be drilled in the predetermined depth soil layer with drilling tools, utilize the static pressure mode that opposite opened cutting ring soil sample barrel is pressed in the boring bottom solum and carry out soil sampling.Place several cutting rings in advance in opposite opened cutting ring soil sample barrel inside, can obtain the standard soil sample that several satisfy the test sample specification requirement simultaneously.From boring, take out opposite opened cutting ring soil sample barrel then, open soil sample barrel, cutting ring is taken out from soil sample barrel one by one, and cutting ring is placed in the soil sample preservation case compresses, seal and be sent to the laboratory with cutting native cutter.Again other a collection of cutting ring is placed into the work of next time fetching earth in the soil sample barrel.
Because testing crew can directly utilize the cutting ring sample that takes out from soil sample barrel to test, guaranteed accuracy, the success ratio of test, improved work efficiency.
The utlity model has following characteristics:
1. prepare soil sample efficient height.Utilize this soil sample barrel, can disposablely successfully make the required soil sample of several laboratory soil tests.Traditional sampling mode is: the cutting ring cutting edge is to being placed down in vertical depression on the soil sample, and with cutting native cutter along cutting ring outside cutting soil sample, the transformation change is cut to the soil sample upper end and is exceeded cutting ring, then with fret-saw or cut native cutter and soil sample is cut off along the cutting ring downside, and leveling cutting ring two ends soil sample, finish the preparation work of a soil sample.
2, the kind of preparation test specimen is many.Utilize this soil sample barrel, can successfully make loosely organized test specimens such as silt, sand.The traditional preparation process method can't be shaped for loosely organized samples such as silt, sands, makes whole soil sample structure cave in cutting native cutter when soil sample is cut in the cutting ring outside, can't make the sample of test usefulness.
3, little to the test sample disturbance, test accuracy height.Adopting the obtained sample of opposite opened cutting ring soil sample barrel is disposable in-situ preparing, reduced manually repeatedly with fret-saw with repair native cutter working angles, reduced degree to the soil sample disturbance.
Because the protection of cutting ring and the sealed at both ends lid of cutting ring is arranged, all kinds of influences that the former body structure of soil sample, the content of water etc. are subjected to are less from the scene to the laboratory handling process.
There are some open areas in the soil sample barrel head, and the foot of hole relict soil is extruded from this, and soil sample is not produced compacted influence.Soil sample barrel top commonly used is for sealing, when the foot of hole relict soil produces artificial compacted effect to soil sample more easily.
The design of the cutting edge of shoe effectively reduces the resistance of soil layer in the process of fetching earth and to the pressure influence of soil sample, makes the sample that the fetches earth structure that maintains the original state as far as possible.
Employing is cut native cutter and can be cut off the soil sample section fully when cutting apart cutting ring, reduces the disturbance to soil sample.
4, simple to operate, easy to use.This soil sample barrel adopts removable built-in cutting ring, uses very easy.
Because soil sample barrel adopts opposite opened structure and inside that some undercuts are set, fetch earth finish after, open half soil sample barrel, can cut apart in the soil body between each cutting ring very easily.Adopt when cutting apart soil sample and cut native cutter and easily separate each sample cutting ring.
5, expense is low, the work efficiency height.Opposite opened cutting ring soil sample barrel is simple in structure, and cost is lower.Because on-the-spot specification of being materialsed satisfies testing requirements, can test immediately after delivering to the laboratory, shortened the duration, improved work efficiency.
