Abstract
The utility model relates to a portable vane-shear apparatus capable of testing the undrained shear strength of a soil body in site and in real time. The portable vane-shear apparatus comprises a torque transducer, a vane head connected with the bottom end of a rotation rod, a limiting clamp for limiting the horizontal displacement of the rotation rod, a control cabinet arranged on a beam, and a rod clamping device arranged above the control cabinet. The portable vane-shear apparatus is characterized in that the apparatus also comprises a reducer in the control cabinet, the reducer is coaxially fixed with a driving wheel, and a driven wheel is coaxially fixed with the rotation rod. The torque transducer is fixed in the rotation rod to be in a whole with the rotation rod and is arranged below the limiting clamp. The portable vane-shear apparatus has relatively high precision and good portability, and can be well applied to testing the undrained shear strength of the soil body in a test for testing columnar samples of field superficial part soft clay in a sampling barrel, or an indoor model test.
Description
Technical field
The utility model relates to a kind of soil body proving installation, relates to a kind of portable vane apparatus of in-situ test soil body undrained shear strength specifically.
Background technology
The soil strength index is the important parameter of building foundation design and Slope Stability Evaluation.The soil body causes various disturbances easily in sampling, transportation, process of the test, especially for the strong soft clay of sensitivity macrostructure property, and the intensity index distortion in various degree that disturbance causes shop experiments such as staight scissors, three to obtain.Vane shear test is applicable to the undrained shear strength of the full water soft clay of in-site detecting, has avoided the change of soil sample disturbance and the natural stress state of the soil body.Vane shear test was brought into use in China from 1954, had become the wider soil strength in-situ testing method of a kind of application at present.Open-air four-bladed vane test apparatus heavy is operated inconvenience, is not suitable for real-time, quick, the accurately measurement of small scale soil strengths such as indoor model test.Existing miniature vane apparatus adopts index dial and artificial reading; There are various frictions in loading and the shear history; Test accuracy is not enough, and only is applicable to the inner soil strength test of columnar samples sample bucket, is difficult to use in the interior soil strength original position The real time measure of different vessels such as model test.Therefore, a kind ofly have degree of precision, vane apparatus portable, that be applicable to soil strength test in the various indoor model tests such as flume test is very necessary.
Summary of the invention
The utility model provides a kind of portable vane apparatus that is applicable to indoor model test, sampler barrel cylindrical appearance and not draining of the soft clay strength test of open-air superficial part stratum.Be to increase the dirigibility and the applicability of proving installation, improve measuring accuracy, this test unit has adopted portable design, has realized adjustable, the automatic control of shearing of shear rate and the automatic acquisition and recording of shearing moment of torsion.
The technical scheme that the utility model adopted:
A kind of portable vane apparatus; Comprise four-bladed vane wrench that torque sensor, bull stick bottom connect, the horizontal shift of restriction bull stick spacing card, be positioned at control box on the crossbeam, be positioned at the jamming rod device on the control box; It is characterized in that: also comprise the reductor in the control box; Said reductor is coaxial fixing with driving wheel, and follower is coaxial fixing with bull stick.
As the further improvement of present technique scheme, said torque sensor becomes one with bull stick in the middle of being fixed on bull stick, and is positioned at the below of spacing card.
The utility model adopts reductor to drive bull stick and four-bladed vane wrench through driving wheel and follower engagement; Realized the scalable of shear rate and to the uniform and automatic shearing of the soil body, be fixed on torque sensor in the middle of the bull stick and the acquisition system that is attached thereto and realized shearing the collection and the record of moment of torsion.Torque sensor is positioned at the below of follower and spacing card, directly tests the shearing moment of torsion of the soil body, has avoided mechanical friction to improve measuring accuracy.Total system shortage in weight 10kg has good portability.Crossbeam both can be erected at the test that realizes sampler barrel cylindrical appearance in the air; Can be fixed in the test of soil strength in all kinds of indoor model tests such as realizing flume test on the tank again, also available earth anchorage is to be used for the in site measurement of open-air not draining of superficial part soft clay intensity.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Among the figure: 1, four-bladed vane wrench; 2, bull stick; 3, torque sensor; 4, spacing card; 5, control box; 6, jamming rod device; 7, crossbeam; 8, follower; 9, driving wheel; 10, reductor.
Embodiment
As shown in Figure 1; The utility model comprises the acquisition system (omitting among the figure) that links to each other with torque sensor 3, four-bladed vane wrench 1 that bull stick 2 bottoms are connected, limits the spacing card 4 of bull stick 2 horizontal shifts, is positioned at the control box 5 on the crossbeam 7; Be positioned at the jamming rod device on the control box 5; It is characterized in that: also comprise the reductor 10 in the control box 5, said reductor 10 is coaxial fixing with driving wheel 9, and follower 8 is coaxial fixing with bull stick 2.
Said torque sensor 3 becomes one with bull stick 2 in the middle of being fixed on bull stick 2, and is positioned at the below of spacing card 4.
The edge of driving wheel 9 and follower 8 all has gear and is meshing with each other through gear, can drive bull stick 2 and then drive the at the uniform velocity shearing that four-bladed vane wrench 1 is realized the soil body through reductor 10; Regulate reductor 10 rotating speeds and can realize adjusting shear rate.1 of wrench changing different sizes can be to the strength test of the dissimilar soil bodys.But regulate jamming rod device 6 up-down adjustment four-bladed vane wrench 1 embedded depth, thereby realize the soil strength test of different depth.Be fixed on torque sensor 3 in the middle of the bull stick 2 and the acquisition system that is attached thereto, can measure and write down the moment of torsion in the shear history in real time.Control box 5 is placed on two crossbeams 7 so that displacement and fixing.
