Description
Technical field
The present invention relates to the indoor geotechnical testament fields of civil engineering subject, refer in particular to a kind of for the parallel of cutting ring demoulding
Electronic rotation release method.
Background technique
As the security requirement to building is continuously improved, need to just mechanical test be carried out to live sample at the beginning of design.
The main damage form of ground is failure by shear, and direct shear test is the common method of determining soil shear strength.In the test soil body
Shearing strength before, ready soil sample need to be put into cutting ring, the standard of diameter 61.8mm, high 20mm are made using hammering method
Cutting ring sample, then the standard sample in cutting ring is taken out in demoulding, carries out direct shear test and measures its mechanical property.Currently, test
Traditional stripping means are first the demoulding annulus for blocking cutting ring to be placed on direct shear apparatus box, then cutting ring sample is placed in demoulding circle
Ring.It by placing a cylindrical body on cutting ring sample, presses to cylindrical body, so that sample in cutting ring is pressed into direct shear apparatus box
In.During demoulding, it due to being unable to control the application pressure to cutting ring sample, is easy to sample strip come disturbing in varying degrees
It is dynamic, make lower with identity after a collection of staight scissors sample demoulding.Moreover, disposably to demould quantity single for traditional stripping means, so that
The demoulding time for completing whole samples is relatively long.
Following improvement is made that for these problems researcher: " geotechnological cutting ring demoulding device (application number:
CN201520392125.3) " drive hammer that pressure head pushing is made to improve demoulding efficiency by compression bar, but during demoulding still
Biggish disturbance can be generated to the not high sample of hardness." a kind of geotechnique's cutting ring stripper (application number: CN201520337465.6) "
" a kind of with soil test cutting ring stripper (application number: CN201720553147.2) ", fixed cutting ring is motionless, by very heavy
It pushes up and presses to the sample in cutting ring, the sample in cutting ring is made to eject cutting ring.This improved method can save manpower, improve demoulding
Efficiency, but to sample there are still certain perturbation.Since integrality and identity of the direct shear test to sample are more demanding, and
Existing release method is all that fixed cutting ring is motionless, applies vertical pressure to the sample in cutting ring, separates cutting ring with sample.This
A little release methods are done work indirectly to the sample in cutting ring, make it difficult to produce that difference is smaller, the lesser same batch of perturbation
Sample.
Therefore, the present inventor makes further research this, develops a kind of parallel electronic rotation for cutting ring demoulding
Thus release method, this case generate.
Summary of the invention
The purpose of the present invention is to provide a kind of parallel electronic rotation release methods for cutting ring demoulding, existing to solve
Identity after some demoulding equipments are excessive to the perturbation of sample during demoulding, cutting ring sample demoulds is lower, disposable
Demould the problems such as quantity is single.
To achieve the goals above, technical scheme is as follows:
