Abstract
It is used for frozen soil experiment sampling die the utility model discloses one kind, belongs to frozen soil mechanics experimental technique field, be mainly made up of bed die, side form, three parts of fastener, it is characterised in that：The bed die includes base and upper die face, it is fixedly connected between the two by cylinder, cylinder circumference leaves groove, the side form is made up of two pairing semicircular cylinders, bottom is circumferentially interior added with circular arc bar, the fastener includes hex nut and hexagon socket head cap screw, and wherein hex nut is fixed on side form edge.The utility model after the completion of frozen soil sample freezes when being stripped, the instrument of being required for beats side form sampling, realizes fast demoulding, prevents that sample is caused to damage and destroyed, avoid demoulding time long simultaneously so that frozen soil specimen surface melts, causing sample preparation to fail or produced on result of the test influences.
Description
Technical field
The utility model belongs to frozen soil mechanics experimental technique field, is related to a kind of for frozen soil experiment sampling die.
Background technology
According to MT/T 593.1-2011 standards, in Artificial Frozen Soil uniaxial compressive strength test and Artificial Frozen Soil single shaft creep
In experiment, the preparation for freezing remolding soil specimens, the general sample from specification Φ 50*100, sampling die is correspondingly-sized
Cast iron die, sample freezes under required test temperature together with mould after the completion of preparing, carried out after the completion of freezing artificial
The demoulding.Traditional mould has a semicircle side form to be fixed with bed die, and another side form can be dismantled, the sample when temperature is very low
Meeting could be sampled smoothly together with die bonds, it is necessary to tap side form by instrument, and so sample can be produced to a certain degree
Damage, or even sample can be destroyed, can melt specimen surface while striking time is long, caused sample preparation failure or experiment is tied
Fruit produces influence.
The content of the invention
The purpose of this utility model is to overcome problem above to be used for frozen soil experiment sampling die there is provided one kind, convenient de-
Mould, reduces the destruction to sample.
The utility model is achieved through the following technical solutions：
One kind is used for frozen soil experiment sampling die, is mainly made up of bed die, side form, three parts of fastener, its feature exists
In：The bed die includes base and upper die face, is fixedly connected between the two by cylinder, cylinder is placed in the center of base
Place, leaves groove around it, the side form is made up of two pairing semicircular cylinders, and bottom is circumferentially interior added with circular arc bar, side form
Circular arc bar is sticked into groove after pairing, and the fastener includes hex nut and hexagon socket head cap screw, and wherein hex nut amounts to 4
Individual, specification is just as being individually fixed on side form edge, hexagon socket head cap screw amounts to 2, and specification is identical, with hex nut size phase
Matching.
As the preferred embodiment of above-mentioned technical proposal, the hex nut is after side form pairing between two nuts of homonymy
Distance be 6mm.
The utility model has advantages below compared with prior art：
What the utility model was provided is used for frozen soil experiment sampling die, when being stripped after the completion of frozen soil sample freezes, it is not necessary to
Side form is beaten using instrument to sample, and is realized fast demoulding, is prevented from that sample is caused to damage and destroyed, while avoiding demoulding time mistake
It is long that frozen soil specimen surface is melted, cause sample preparation failure or influence is produced on result of the test.Structure design is simple, it is easy to grasp
Make.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1 to Fig. 7, one kind that the present embodiment is provided is used for frozen soil experiment sampling die, mainly includes bed die 1, side
Mould 2,3 three parts of fastener, bed die 1 include base 11 and upper die face 14, fixed connect by cylinder 13 between the two
Connect, cylinder 13 is placed in the center of base 11, leave groove 12 around it, side form 2 (including side form (1) 21 and side form (2)
22) it is made up of two pairing semicircular cylinders, bottom is circumferentially interior added with circular arc bar 4, circular arc bar 4 sticks into groove after the pairing of side form 2
In 12, fastener 3 includes hex nut 31 and hexagon socket head cap screw 32, and wherein hex nut 32 amounts to 4, and specification is just as respectively
It is fixed on the edge of side form 2, the distance after the pairing of side form 2 between two nuts of homonymy is 6mm, hexagon socket head cap screw 32 amounts to 2,
Specification is identical, matches with the size of hex nut 31.
The embodiment provided using the utility model, is distinguished the circular arc bar 4 of side form (1) 21 and side form (2) 22 before sample preparation
Stick into the groove 12 of bed die 1, screw the hexagon socket head cap screw 32 of both sides after being folded successively using inner hexagon spanner, then carry out
Sample preparation.When sample freezes completion and needs form removal, hexagon socket head cap screw 32 is outwarded winding with inner hexagon spanner, remove successively half side form and
Bed die 1, you can convenient to take out sample.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
