Description
Technical field
It the utility model is related to ring shear test test sample-producing die.
Background technology
In recent years, ring shear test has turned into the main method to the research of soil strength under the conditions of large deformation, many countries
Also the long-term and in-depth study of the exploitation to ring shear apparatus and application start, to reach the mesh of increase experimental result accuracy
's.But prepared for ring shear test sample and do not carry out deep probe into.The preparation of sample still uses traditional preparation method.
Traditional preparation method of sample is mainly：Remoulded sample needed for being prepared first with compacting process or concretion method, then with thin-walled type ring
Knife cuts upper and lower unnecessary part, and removes center section with small size cutting ring and be allowed to form hollow sample.
Traditional research technique and method will produce many inevitable errors in operation.First, sample
The control that can not be refined of volume, this can produce very big error for the higher experiment of density requirements, secondly, grasp
During work extruding can be produced to the soil body.The soil body is set to be deformed before being tested；Finally for types such as Foam lightweight soils
Soil sample, its structure has macrovoid, is not suitable for cutting, therefore the method for conventional cut-away can also have inwall to the outer wall of soil sample
Cause damage, it is impossible to make specimen size more accurate etc..
Based on the above situation, it is necessary to study a kind of simple to operate, precisely and the soil sample minimal damage that is prepared to needs
Ring shear test test sample-producing die, the needs of scientific research are met with this.
Utility model content
The purpose of this utility model is to provide a kind of ring shear test test sample-producing die, effectively solves above-mentioned biography with this
The shortcomings that prepared by ring shear test sample of uniting, the operating error of sample making course is reduced, improve the accuracy of experiment.It is above-mentioned in order to realize
Purpose, the technical solution of the utility model are as follows：
A kind of ring shear test test sample-producing die, including base 3, it is characterised in that described mould also include inner ring 1,
Outer shroud 2, base 3 and ring cover 4, offered on base respectively accommodating outside the annular trough of inner ring 1 and outer shroud 2 and annular
Groove, annular trough and annular water jacket are concentric, and described inner ring 1 and outer shroud 2 are spliced by two semi-rings respectively；Ring cover 4
Internal diameter and the external diameter of inner ring 1 match, and the internal diameter of external diameter and outer shroud 2 matches.
Preferably, multiple through holes are distributed with inner ring 1, outer shroud 2 and ring cover 4.Described ring cover 4 is also associated with energy
Enough fixed pillars on the base 3.
The advantages of the utility model is compared with traditional technology is：
First, the sample demoulding is simpler, avoids conventional specimen from needing stripper to disturbing caused by the end pressure of sample one
It is dynamic；
Second, meet the preparation condition of manipulated soil, avoid tradition cutting bulk specimen from just obtaining the artificial mistake of ring specimen
Difference, and the perturbation to the soil body；
3rd, the foamed light soil for meeting to expand foaming in prescribed volume, and volume-tunable；In mould
The attached permeable watertight film of wall, so meet sample gas permeability in maintenance processes, keep internal and external temperature consistent.
In a word, ring shear test caused mistake in sample making course can be efficiently controlled by preparing sample using this mould
Difference.

Embodiment
In order to further appreciate that utility model content, feature and effect of the present utility model, embodiment is hereby enumerated, and
Accompanying drawing is coordinated to describe in detail as follows：
Fig. 1, Fig. 2, two kinds of ring shear test test sample-producing dies of offer of the present utility model are referred to, one kind can make foaming
Sample such as solidified light soil, another kind can make non-foamed sample (such as manipulated soil), by inner ring 1, outer shroud 2, base 3 and
Ring cover 4 forms.
Mould uses stainless steel material, reaches some strength with intensity, ensures the accuracy of sample.
The inner ring 1 of mould, outer shroud 2 divide equally two halves, and sample directly breaks mould into two with one's hands and takes out sample after conserving, avoid routine
It is stripped the extruding to sample.
Inner ring 1, outer shroud 2 are fixed on base in the form of inlaying, and it is 3-4mm that base, which inlays trough (to be not drawn into) depth in figure,
Left and right, mould is directly extracted after being molded in order to sample.
The ring cover 4 of mould connects two pillars 5 that can be fixed in steel plate base 3, and the pillar 5 is consolidated with thread forms
It is fixed that ring cover be connected with branch intercolumniation with 2mm wide walls on the base 3, thus caused by space use between semicircle breathe freely it is impermeable
Water paper subsidizes on the inside of annular outer wall.While ensureing that soil sample will not flow out, in order to adjust the height of ring cover 4 to reach
The purpose of Control Assay volume.
The mould of foaming sample is prepared, gathers and punches in inner ring 1, outer shroud 2 and ring cover 4, in order to which sample is being supported
The circulation of gas during shield.And spread an equal amount of permeable watertight paper at ring inwall and bottom, with ensure sample it is ventilative but
Will not current lose, the permeable watertight paper capping of same loop size is bonded after the completion of preparation on ring cover.
Now exemplified by preparing the ring of manipulated soil and solidified light soil and cut sample, illustrate that the utility model prepares different examinations respectively
The specifically used process of sample, specific implementation operation are as follows：
