System.The design principle of hollow cylinder small sample sample-pressing device described herein (other samples prepare close therewith).
1) pressure-like designs
When preparing three axis sample of remodeling, if sample is divided into dried layer generally according to correlation test specification, then uses and divide
Layer compacting process, sample compacting will be tried by larger hammer of conducting oneself with dignity in real time by hitting.However, the impact force due to hammer is larger, real mistake is hit
Journey inevitably generates Secondary Disturbance to the soil body, makes inside remodeling sample that there are microfissures, reduces the credible of follow-up test
Degree.The present invention is eliminated and is hit in fact to soil body Secondary Disturbance, reduced and artificially hit real error, maximum journey using layering pressure-like method
Degree simulation natural rock-filled deposits forming process, improves the quality of remodeling sample.
2) dynamical system designs
The present invention uses hydraulic power system, greatly reduces the intensity of manual labor.Traditional compacting process is dry in preparation
Density is larger, intensity higher sample when, it is not only time-consuming and laborious, but also sample mass is poor, since oil hydraulic system has pressure
Greatly, the features such as stability is good, easily controllable so that the pressure-like device has unique advantage when preparing such sample, improves
The applicability of sample preparation equipment.
3) power and Control System Design
It usually requires manually to estimate specimen height when preparing remodeling sample, comes the uniformity of Control Assay, this method
It can not reliably ensure the quality of sample.Inbuilt displacement meter and control mechanism 8 of the present invention, in real time detection move pressure-like platform
Position, and control mechanism, displacement meter and dynamical system are formed into a servo feedback system, target position is inputted by control mechanism
It moves, to control the position of removable pressure-like platform, strictly to control the height of every layer of sample, not only realizes the half of sample preparation
Automation, and the uniformity coefficient for improving sample of maximum possible.
4) pressure-like bar is designed with pressure-like hammer
The present invention transmits vertical pressure using pressure-like bar rather than pressure-like cylinder, reduce pressure-like system with it is inside and outside at mould cylinder
Between friction, moreover, by the gap between bar, can observe in real time it is inside and outside at mould cylinder position, pressure-like hammer and latex film whether there is or not
Situations such as whether scraping, soil sample particle squeeze out.Pressure-like bar 20 is three fan-shaped bars, and the stainless steel plate using thick 5mm, width 20mm is curved
Make, length with it is inside and outside identical at mould cylinder.20 lower end of pressure-like bar is connected with pressure-like hammer 21, and pressure-like is hammered into shape inside and outside bottom
Enlargement Design is done, so that sample upper surface uniform force when pressure-like.In addition, in order to avoid pressure-like hammer with inside and outside latex film it
Between phase mutual friction, latex film pullled deformation by pressure-like hammer and causes sample local defect, and pressure-like hammer stretches into cavity between the inside and outside cylinder at mould
Afterwards, need to retain between inside and outside latex film the gap of 1mm with convenient to operate.Inside and outside latex film is when for preparing hollow cylinder sample institute
Necessary auxiliary consumptive material has been widely applied in geotechnological field.
5) at mould cylinder valve designs
It is inside and outside to be all made of valve designs at mould cylinder, consider into mould cylinder globality and the convenience of dismounting, it is outer at mould cylinder
13 are made of three identical valves；It is interior to be made of with two small valves 26 two big valve 25 at mould cylinder 14, inside
There is the card slot 34 of fixed side arm 35.Inner bracing piece 15, outer garter spring 12 and specimen mount are inside and outside common at mould cylinder fixing groove 29,28
It supports and fixes inside and outside at modular system, prevents when pressure-like sample lateral expansion excessive and make into modular system and deform.
6) it is designed at mould cylinder top cap
When prepared by sample, soil particle can fall into it is inside and outside at the gap between mould cylinder lower end and specimen mount at, with pressure-like
The increase of pressure, soil particle are constantly squeezed into gap, are caused inside and outside at the inclination of mould cylinder.Thus, inside and outside at mould cylinder top
End, fixed by inside and outside supporting rod it is inside and outside at mould cylinder top cap, the two respectively with it is inside and outside at mould cylinder joint continuity, it is close.It is interior at
Mould cylinder top cap cuff inside at mould cylinder top, outside with it is interior identical at mould cylinder outside diameter；It is outer at mould cylinder top cap cuff outside
At mould cylinder top, inside with it is outer identical at mould cylinder inside diameter.Then, it is inside and outside at mould cylinder vertical pressure effect under, with examination
Sample pedestal closely connects, to prevent soil particle to be extruded.It is inside and outside at mould cylinder top cap in the embedded specimen mount part of deduction and insertion
It, should be contour with sample at mould cylinder and sample contacts section height behind part.Since last several layers of soil samples are fluffy before hitting in fact, because
And it is inside and outside also acted as at the extended effect of mould cylinder at mould cylinder top cap, the inside and outside height at mould cylinder top cap is can just accommodate
Last layer of soil is standard, rule of thumb 80,100, the sample top cap height of 200mm high be 25mm, the sample top cap of 400mm high
Height is 50mm.
7) sample one-pass molding designs
When preparing hollow cylinder sample, the solid cylindrical sample that generally use first prepares height and outer diameter is met the requirements,
Then, by solid sample coring, hollow cylinder sample is obtained.However, coring operation is larger to sample disturbance, and for intensity
Soil higher, particle is larger, sample coring become abnormal difficult.The present invention is when preparing hollow cylinder sample, using compacting,
Hollow cylinder sample is once made, to the Secondary Disturbance of sample when avoiding coring, improves the applicability of the pressure-like device.
8) applicability designs
In order to prepare the different sample of height, the top plate of pressure-like device can be by lifting with the screw thread on side lever so that can
The range of mobile platform can meet the requirement for preparing various sample.Cheng Mo and pressure-like system are detachable, according to made
Standby sample replaces corresponding device, in addition, mould and pressure-like system can be also customized to according to actual conditions.One-pass molding sample preparation,
