Description
Technical field
The present invention relates to geotechnical investigations technical field, and in particular to a kind of for field vane shear test and the one of sampling
Makeup is put, and the device can obtain undisturbed soil sample, and and can measures natural rock-filled field vane shear test intensity level and pore water pressure force value.
Background technology
In engineer geological prospecting, to expect the physics and mechanical index of soil, rely primarily at present in drill sampling room
Experiment obtains.But in sampling, soil sample exists with sampler barrel inwall to rub；During laboratory test, soil-shifting process will again result in soil
Rubbed between sample and sampler barrel, so that being recompressed after stress relaxation, cause obtained mechanical strength index distortion.Vane-shear
Experiment is that scene applies torsion by the cross wrench inserted in soil, cross wrench constant speed in soil is reversed until the soil body is cut
Damage, the peak torque that cylinder surface is formed when measuring rotation, so as to calculate unearthed undrained shear strength cuValue.Before
Person, more real physical data can be obtained；The latter, real mechanical strength index can be obtained.Existing work pattern,
First drilled in place to be measured, soil sampler sampling is then put into out of hole or is put into cross wrench and implements in-situ test, how once
Drilling, can get undisturbed soil sample, and and can completes vane shear test, this problem long-standing problem Geotechnical Engineering circle.
The similar solution in part is disclosed in the prior art, and the Chinese invention such as Application No. 201110132843.3 is special
Profit discloses a kind of " a kind of vane-shear apparatus for reconnaissance survey ", proposes the protection sleeve pipe of suit sealing on the outside of main shaft, makes protective case
Pipe lower end is fixed on four-bladed vane, during torsion working-spindle not with soil friction, so as to improve field vane shear test measurement accuracy.
In addition, Chinese invention patent CN 104458445A disclose " shearing test device and experiment in a kind of in-situ soil body opening
Method ", experimental rig is put into bottom hole using after drill hole of drilling machine, applies air pressure and drive shearing cylinder bulging, make soil solidifying；Apply
Hydraulic pressure drives the shear knife shearing soil body, makes soil body failure by shear, by the Shear Strength Index that the soil body in situ is calculated.
In above-mentioned technology, the former is pressed for drilling rod in vane shear test, and sensor is replaced into conventional test methods, made
The soil body resistance moment of torsion accuracy of reading measured improves.In reality, the cross plate shearing instrument on ground or platform, to drilling rod one
End applies moment of torsion and is delivered on the cross wrench of distal end, can produce the elastic deformation such as bending or distortion, and the portion of drilling rod and hole wall
Centimorgan wipe, then the longer elastic deformation of drilling rod is bigger by Kong Yueshen, causes obtained field vane shear test data distortion.The latter is fully sharp
With drilling, the Natural gas composition index of soil is obtained using cutting method in in-situ soil body opening, but can not synchronously obtain soil water content,
The physical indexs such as void ratio and pore water pressure.
As the depths of foundation such as Geotechnical Engineering builds, bridge, harbour, man-made island tunnel constantly extend, people increasingly expect
A kind of low cost, high quality synchronously complete sampling, field vane shear test, the integration unit for measuring pore water pressure.

Method.Broadly, this method includes：Device → B field vane shear tests → C borehole cleanings → D samplings are put in A drillings, such a complete
Work flow.It is described as follows：
A, device is put in drilling：State A in reference picture 6, first in exploratory spot drill hole of drilling machine to projected depth, then will
The integrated apparatus of the present invention is connected to the lower end of drilling rod 52, and bottom hole is put into after being lengthened section by section by drilling rod 52；If not up to specify
Depth, then using flushing liquor wash boring (with reference to following steps C), bottom hole soil particle is carried out in drilling, it is ensured that device arrives
Up to designated depth.
B, field vane shear test：Then, starting lifting motor 13 drives screw mandrel 12 to rotate, and makes torsion motor 15 and cross wrench
16 move downwardly together, until cross wrench 16 exposes from the lower end of cylinder 11, and are inserted into the set depth of the bottom hole soil body, reference
State B in Fig. 6；If the lower end of cross wrench 16 is provided with pore water pressure sensor, pore water pressure sensor is first used
Measure the pore water pressure force value of the soil body；Then field vane shear test is carried out, starts and reverses the drive cross of motor 15 wrench 16 by initial
The speed of setting is reversed, and twisting resistance of the cross wrench 16 in the original state soil body is measured by the torque sensor being arranged on axostylus axostyle 26
Square, until obtaining torque peak or stationary value Cu of the cross wrench in the original state soil body；Then reverse motor 15 and drive four-bladed vane
First 16 continue to rotate, and the soil body around cross wrench is fully disturbed, then measure moment of torsion peak of the cross wrench in disturbed soil
Value or stationary value Cu '；Soil body undrained shear strength can be calculated according to maximum torque.
C, borehole cleaning：After the completion of field vane shear test, start lifting motor 13 and rotate backward, make torsion motor 15 and cross wrench
16 move upwardly together, and return to the top of sampler barrel, the state C in reference picture 6；Start flushing pump by flushing liquor from tap 51
Place's press-in drilling rod 52, flushing liquor injects cylinder lumen up to bottom hole along drilling rod, and is flowed out outside cylinder between hole wall, flows back to
Circulatory pool (not shown).The soil particle of bottom hole gradually flows to the outside in hole with flushing liquor, as drilling rod 52 is lifted and rinsed repeatedly
Liquid is impacted, and the perturbing area soil body formed after above-mentioned field vane shear test is cleaned out, until bottom hole is located on the original soil body.
D, sample：Rig uses plunging or is driven into method and will complete undisturbed soil in the sampler barrel injection soil of cylinder lower end and take
Sample.Drive torsion motor 15 and cross wrench 16 to continue to move up at this point it is possible to start lifting motor 13, make the top of torsion motor 15
The bottom surface of sealing gasket 25 and diaphragm plate 14 be in close contact, the state D in reference picture 6, prevent flushing liquor from flowing into cylinder lower chambers,
The lower chambers above soil sample is formed confined space simultaneously, if soil sample glides because of deadweight, vacuum will be formed on top,
So as to prevent soil sample from further gliding, it is ensured that soil sample will not fall off.Last rig lifting drilling rod 52, until the integration of the present invention
Ground is arrived in device lifting.Reference picture 4, cylinder hypomere and stage casing are separated, and screw off shoe 29, separated two semicircular cylinders 27, take
Go out the sampler barrel 50 (being undisturbed soil sample 55 in cylinder) of inside, cover 54 is added at the both ends of sampler barrel 50, in sampler barrel 50 and cylinder
Gap between lid 54 affixes strip of paper used for sealing, applies cured rear storage, finally send soil mechanics laboratory.
After completing above-mentioned test procedure, device is re-assemblied, can again drill to next depth, repeat above-mentioned
Step A puts device → B field vane shear tests → C borehole cleanings → D samplings, until whole drilling reaches projected depth.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and replacement can also be made, these improve and replaced
Also it should be regarded as protection scope of the present invention.
