Description
Technical field
The utility model belongs to highway construction technology field, particularly a kind of mould preparing unconfined compression strength test sample.
Background technology
Unconfined compression strength test is widely used in other each fields such as highway subgrade basic unit, subbase, and important technology directive function is played in the control of its test findings to project under construction quality.So it is regular for detecting this index in testing.
The basic operation process of this test is that the sample got ready is in advance loaded die trial; then compressing in a press; the demoulding is carried out in ingot stripper; again according to the requirement of standard at certain hour, certain wet, (temperature of Standard Curing is 20 DEG C ± 2 DEG C to temperature; humidity is for >=95%) carry out maintenance under controlled condition; soak one day, finally on pressing machine, carry out compression test, obtain its compression strength value.
The test method that unconfined compression strength test is the physics of stabilized with inorganic binder material, mechanical test often will be used.The starting material of unconfined compression strength test are divided into coarse-grained soil, middle grain soil and fine grained soil, have cement, lime, flyash etc. according to the stabilizing material that the requirement of construction is conventional.If stablize other material with cement, that its first final setting time of just first will knowing for sure, the in good time demoulding, thus ensure the complete of test specimen, to die trial itself also without damaging.If do not considered this parameter setting time of cement, the demoulding immediately after product, can have a greatly reduced quality to the shaping of test specimen, the integrality of test specimen can not be guaranteed; Otherwise; demould time exceeds the final setting time of cement; be bonded to one directly causing test specimen and die trial inwall; test specimen also cannot intactly be deviate from by ingot stripper; integrity degree and the corresponding quality requirements of test specimen all do not reach guarantee; cause the undesirable situation of test specimen to occur, also delay the detection time of whole test, delay is reported the result.
Therefore, prepare in test specimen process at unconfined compression strength test, due to die trial inside surface coarse cause product material adhesion on die trial inwall and upper lower cushion block or die trial clean not thorough, cause made test specimen breakage or test specimen quality to run off, cause the appearance of the undesirable situation of test specimen.
Summary of the invention
The utility model for solve in known technology the technical matters that exists and provide a kind of can the mould preparing unconfined compression strength test sample of qualification rate of test specimen.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
A kind of mould preparing unconfined compression strength test sample, comprise die trial, described die trial is tubular structure, described die trial inwall is provided with inwall machine oil layer, described die trial inner bottom part is provided with lower lock block, the top plane of described lower lock block is provided with one deck lower end machine oil layer, machine oil layer top, described lower end is provided with the first filter paper layer, described first filter paper layer contacts with sample layer, described sample layer upper end contacts with the second filter paper layer, described second filter paper layer contacts with upper end machine oil layer, and described upper end machine oil layer is arranged on the baseplane of upper holder block.
Described first filter paper layer and/or the second filter paper layer can be substituted by plastic sheeting.
Described upper holder block and lower lock block one side center is toward the outer side provided with circular hole.
The advantage that the utility model has and good effect are: the utility model is by arranging machine oil layer at die trial inwall and upper holder block bottom surface, lower lock block end face, at upper and lower briquetting and sample contacts place, filter paper or plastic sheeting are set, solve the sticky and die trial of product material and clean halfway problem, and improve the qualification rate preparing test specimen, decrease and cause product again because manual operation reason causes error in process of the test, avoid the waste of manpower and materials.
Accompanying drawing explanation
Fig. 1 is the utility model perspective cross-sectional structural representation.
In Fig. 1,1. upper holder block, 2. upper end machine oil layer, 3. inwall machine oil layer, 4. the second filter paper layer, 5. die trial, 6. the first filter paper layer, 7. lower end machine oil layer, 8. lower lock block, 9. sample layer.
Embodiment:
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See Fig. 1, a kind of mould preparing unconfined compression strength test sample, comprise die trial 5, die trial 5 is tubular structure, the inwall of die trial 5 is provided with inwall machine oil layer 3, die trial 5 inner bottom part is provided with lower lock block 8, the top plane of lower lock block 8 is provided with one deck lower end machine oil layer 7, machine oil layer 7 top, lower end is provided with the first filter paper layer 6, first filter paper layer 6 contacts with sample layer 9, sample layer 9 upper end contacts with the second filter paper layer 4, and the second filter paper layer 4 contacts with upper end machine oil layer 2, and upper end machine oil layer 2 is arranged on the baseplane of upper holder block 1.
Preferably, the first filter paper layer 6 and/or the second filter paper layer 4 can be substituted by plastic sheeting.
Preferably, upper holder block 1 and lower lock block 8 one side center is toward the outer side provided with circular hole.
When the utility model uses, its step is as follows:
(1) maintaining the stage at ordinary times, soaking putting into machine oil after the die trial inwall brush cleaning preparing test specimen; The one side of upper holder block and lower lock block and sample contacts adheres to one deck upper end machine oil layer and lower end machine oil layer;
(2) prepare the product stage at sample, die trial taken out from machine oil, clean with rag, now can adhere to one deck inwall machine oil layer at die trial inwall, inwall machine oil layer plays lubrication and reduces the effect of material adhesion inwall in product process;
(3) preparing the test specimen stage, between the upper cushion block and sample at the upper and lower two ends of die trial, between lower cushion block and sample, adding a filter paper or plastic sheeting, the adhesion of material to upper lower cushion block can be reduced;
(4) state that big-and-middle-sized test specimen just should allow sample keep smooth in die trial when charging is as far as possible made, thus ensure compressing on pressing machine on lower lock block energy smooth vertical press-in die trial in, make sample uniform force, to guarantee the integrality of test specimen;
(5) after experiment, with rag and hairbrush thoroughly clean die trial, then put into machine oil and maintain.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that and still can modify to the embodiment of utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology of the utility model request protection.
