Description
Technical field
It is especially a kind of to be applied to the standard examination of energy accurate calibration rock-like materials the present invention relates to a kind of new processing mold
Sample ruler cun, the interrupted Built-Up Crack of rock-like materials standard specimen that and can processes any discontinuously Built-Up Crack on the same device add
Tool and mould.
Background technology
A large amount of cracks more developed in natural rock medium be present, under the complicated geological environments such as high temperature, high stress, split
Gap easily extends, penetrated, and forms large-scale water flowing fractured zone, aggravates underground engineering draining difficulty, hinders engineering construction to enter
Degree.Therefore from basis, research multidimensional Crack Extension, insertion rule, can be provided for the preventing and treating of its correlation engineering disaster important
Theoretical foundation.However, discontinuity and uncertainty due to natural rock media interior structure, it is more difficult to determine crackle combination side
Formula, influence of the discharge other factors to result of the test, therefore using can extemporaneous preparation more uniform mechanical property it is similar
Rock-like materials replace natural rock medium to carry out correlative study.But prepare at the scene rock-like materials standard specimens (50 ×
It during 100mm), according to common mould, when the rock-like materials excess of perfusion, can only manually be acted upon, grasp
It is complex, inconvenient to make, and can not accurate calibration standard specimen height, it is difficult to prepare more accurate 50 × 100mm standards
Sample, have a strong impact on the accuracy of result of the test.On the other hand, specific crack spacing and relative angle are being prepared using common die
During the interrupted Built-Up Crack of degree, one set of die can only prepare the interrupted crackle of one group of particular combination mode, and this just needs processing more
Individual mould come meet experiment requirement, utilization is more inconvenient, thus design one kind can accurate calibration rock-like materials standard examination
Sample ruler cun, and can process the novel die of any discontinuously Built-Up Crack to carrying out crack propagation, insertion rule on the same device
Experimental study it is most important.
The content of the invention
Technical problem：The purpose of the present invention is to be directed to weak point of the prior art, there is provided a kind of easy to process, conveniently
Operation, the rocks material for being used for crack propagation law research that standard specimen size can be accurately positioned, change crack combination
Expect the interrupted Built-Up Crack processing mold of standard specimen.
Technical scheme：For achieving the above object, the interrupted Built-Up Crack of rock-like materials standard specimen of the invention adds
Top cover on tool and mould, including base, the separable frame mould being located on base, separable frame mould, the separable frame mould is interior
Open semicircle groove symmetrically fastens to be formed for the module of interior circular groove, and it is tight through steel plate and bolt that interior open semicircle groove symmetrically fastens two side seams
It is solidified as a whole；Both sides are symmetrically embedded with two rail sliding blocks of different size before and after the inwall of the interior circular groove, and two rails are slided
Rectangle steel disc can be made to different rotary angle and the rectangle sipes of size between being through at two sliding blocks by being arranged with block, can be pre-
Make the interrupted Built-Up Crack of different spacing and relative angle；The top of described separable frame mould is provided with inclining by top closure
Positioning discharge gate obliquely.
Described top cover is identical with understructure, is formed by rectangular steel plates and ears disk, and ears disk is with separating
The sliding block of frame mould both sides matches.
The opening lowest part of described positioning discharge gate is away from base 100mm.
Fixed handle is symmetrically set on described separable frame mould outer wall.
Beneficial effect：By adopting the above-described technical solution, the present invention can directly prefabricated different crack combinations class
Rock standard specimen, simple in construction, specification is rigorous.Mould can primary concreting into the intermittent joints available for compression test of rock
Cylinder rocks test specimen, compared with prior art, has the following advantages that：
1) can primary concreting obtain rock-like materials standard specimen, by reserved positioning discharge gate, system can be effectively reduced
Influenceed during standby as manual operation error to caused by specimen size；
2) top cover uses special ears disc-shape with base, while sealing is ensured, makes integral disassembly, assembly convenient；
3) the separable frame mould part used, the both sides that circular groove is opened in it embed the rail sliding block of different size, and rail is slided
Block is provided with the rectangle sipes of different rotary angle and size, rectangle steel disc can by rectangle sipes to be through at two sliding blocks it
Between, by changing rail sliding block stacked system and specification, you can the rock-like materials standard specimen of prefabricated intermittent joints combination, and
Crack is not easy to misplace in prefabrication process.
