Description
Technical field:
The present invention relates to a kind of high torque type release method for cutting ring demoulding, the interior geotechnique for belonging to civil engineering subject is real
Test field.
Background technique:
As the requirement to building safety and durability is continuously improved, the mechanical test of ground soil sample is required also increasingly
It is high.Since the main damage form of soil is failure by shear, direct shear test is the common methods of determining soil shear strength.It is testing
Before the shearing strength of the soil body, the standard cutting ring sample of diameter 61.8mm, high 20mm need to be made first with hammering method, then taken off
Mould takes out cutting ring and obtains standard sample, finally carries out direct shear test.And the standard for whether successfully directly affecting direct shear test demoulded
True property.Currently, the stripping means in laboratory are first demoulding annulus to be placed on direct shear apparatus box, then cutting ring sample is placed in demoulding
On annulus, by placing a round demoulding stone on cutting ring sample, press to circle demoulding stone, thus by cutting ring
Sample is pressed into direct shear apparatus box.Due to being unable to control the pressure to cutting ring sample during demoulding, it is possible to sample
It can still press to cutting ring sample after completing demoulding, cause this stripping means to exist more and to hard by artifical influence factor
The problems such as lower sample disturbance is excessive is spent, the accuracy of test result is influenced.
Following improvement is made that for these problems researcher: " geotechnological cutting ring demoulding device (application number:
CN201520392125.3) ", directly demoulded by using stripper and replace hand-stripping, improve demoulding efficiency, but demoulding
Still biggish disturbance can be generated to the not high sample of hardness in the process, while also more by the factor of man's activity.A kind of " geotechnique
Cutting ring stripper (application number: CN201520337465.6) " and " it is a kind of with soil test cutting ring stripper (application number:
CN201720553147.2) ", the fixed cutting ring of both strippers is motionless, is pressed by the sample in jack pair cutting ring by ring
Knife is separated with sample, and this improvement can avoid the influence of human factor to a certain extent, keeps the power of pressure relatively uniform, but
Disturbance is also easy to produce during the cutting ring sample after demoulding is put into the shear box of direct shear apparatus.Since direct shear test need to exist to sample
It is sheared under different vertical pressures, it is desirable that the difference between all samples is the smaller the better.And traditional release method is all fixed
Cutting ring is motionless, applies vertical pressure to the sample in cutting ring, so that cutting ring is separated with sample.This kind of release method, which all exists, to be difficult to
It accurately controls and applies the size of vertical pressure, can still apply vertical pressure to the sample that demoulding is completed and artificial disturbance is big etc. asks
Topic, so that sample differs greatly.Therefore, the present invention has done further research to this, develop it is a kind of for cutting ring demoulding
High torque type release method meets test demand.

Filter paper；Fitros is the cylindrical body permeable stone of overall diameter 61.8mm, thickness 5mm, is placed in sample card slot.
10. a kind of high torque type release method for cutting ring demoulding, which comprises the steps of:
(1) prepare cutting ring sample:
Cutting ring inner wall is uniformly smeared with vaseline, soil sample is layered in cutting ring using hammering method and hits reality, makes its shape in cutting ring
At sample, it is finally made standard cutting ring sample, while cutting the size of filter paper according to the interior diameter of cutting ring；
(2) fixed cutting ring sample:
The side outer wall of cutting ring sample is close to the connecting plate on rotation outer ring, is close to the another of cutting ring sample with pressure piece
Side outer wall；Pressure bolt is passed through into pressure bolt hole, pressure bolt is turned, so that it is held out against the power transmission slot of pressure on piece, by applying
Tabletting and power transmission slot transmit pressure, fix cutting ring sample；
(3) stripping station is assembled:
Demoulding cylinder is put on support cylinder, so that the two joggle, constitutes stripping station；
(4) it demoulds:
(4.1) locking ring device is placed:
The filter paper cut out in advance is first placed in the demoulding cylinder upper surface of stripping station, then the locking ring device that will fix cutting ring sample
It is placed on demoulding cylinder, is aligned demoulding cylinder center up and down with the cutting ring sample in locking ring device；
(4.2) cutting ring sample is separated:
It holds with a firm grip the stress slots of fixed cylinder two sides, is placed on the rotating handles of locking ring device on the other hand, to backspin drop snap ring dress on the other hand
It sets, drives cutting ring to rotate downwardly together by rotation drop locking ring device, separate cutting ring with sample；After cutting ring is separated with sample,
Continue the locking ring device rotation with cutting ring being down to support cylindrical base；
(5) sample is placed:
Filter paper and fitros are successively put on the sample separated, left hand, which is held with a firm grip, demoulds cylinder, and the right hand is held steadily direct shear apparatus box；First
Direct shear apparatus box is inverted and is placed on right above fitros surface, then direct shear apparatus box is slowly moved down, until fitros and sample fill up directly
Cut instrument box；After demoulding cylinder and direct shear apparatus box are finally spun upside down 180 ° together, demoulding cylinder is slowly removed, so that it is complete to fill sample
At；
(6) cutting ring is taken out:
Locking ring device with cutting ring is taken out from stripping station, unscrews pressure bolt, takes out cutting ring and pressure piece；
(7) instrument is arranged:
After the completion of operation, clean it up all appts equipment simultaneously restores its position.
