The utility model discloses can be used to indoor or field measurement inviscid coarse grained soil's angle of repose, as long as stack enough amount of coarse grained soil for a cone, through a lot of measurements, just can guarantee the accuracy that angle of repose calculated, have convenient and fast, accurate, advantage that the test cost is low.
Description
Technical field
The utility model relates to a kind of for measuring the experimental rig at inviscid coarse-grained soil angle of repose, belong to the angular measurement that stops
Technical field is in the angle of repose of the coarse-grained soil material heap of dormant state suitable for indoor or field measurement.
Background technique
Angle of repose refers to that discrete material carries out free accumulation under the effect of gravity, the particle sliding in the freedom of accumulation body
When suffered gravity and particle between frictional force reach balance and the maximum angular measured that remains static down.Angle of repose reflects scattered
Frictional behavior between body material granule reflects the shape feature and its mechanical property of particle to a certain extent, therefore in rock
It is a need parameter to be tested in soil test.
Current angle of repose test method is only for fine grained soils such as sand, granules.The method at test fine grained soil angle of repose has
Two kinds, one kind is injection method, i.e., fine is fallen within by funnel outflow and forms cone in plane, and cone base angle is angle of repose.
Another kind is discharge method, and bulk granular material is from container bottom row's gap discharge, and material inclined surface and bottom are flat after material stops flowing
The angle in face is angle of repose.
Both the above is the method for testing the angle of repose of fine grained soil, and instrument size used is smaller.For coarse-grained soil
Speech, grain diameter maximum need to manufacture and coarse-grained soil maximum grain up to several tens cm with the measurement method at fine grained soil angle of repose
The measuring instrument that diameter matches, the size that this will lead to measuring instrument is very huge, and makes manufacturing cost huge, therefore uncomfortable
It is suitable for the angle of repose for measuring inviscid coarse-grained soil.
Utility model content
In order to solve the above technical problems, the utility model provide it is a kind of for measuring the examination at inviscid coarse-grained soil angle of repose
Experiment device, this is used to measure the experimental rig at inviscid coarse-grained soil angle of repose, can the inviscid coarse-grained soil of rapid survey angle of repose,
And the result obtained is more accurate, has the characteristics that quick, accurate, experimentation cost is low.
The utility model is achieved by the following technical programs.
It is provided by the utility model a kind of for measuring the experimental rig at inviscid coarse-grained soil angle of repose, including cross bar and branch
Frame；There are two the brackets and arranged in parallel, and one is equipped on bracket can measure the branch of horizontal and vertical direction length
Support；The cross bar is connect by sleeve with support frame；The cross bar, support frame are equipped with scale；The sleeve is equipped with one
Vertical window.
Support frame as described above and bracket form T-type rigid fixation structure.
The scale of one end that support frame as described above is connect with bracket is zero.
The sleeve is movably fixed on support frame by bolt.
The cross bar, sleeve, bracket, support frame form an overall structure.
The cross bar, sleeve, rigid movable connection between support frame.
The utility model has the beneficial effects that: can be used for indoor or the inviscid coarse-grained soil of field measurement angle of repose, only
It is a cone that the coarse-grained soil of sufficient amount, which is stacked, by repeatedly measuring, so that it may guarantee the accuracy that angle of repose calculates, have
Advantage convenient and efficient, accurate, experimentation cost is low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the operation schematic diagram of the utility model；
In figure: 1- cross bar, 2- sleeve, 3- bracket, 4- support frame.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of for measuring the experimental rig at inviscid coarse-grained soil angle of repose, including cross bar 1 and bracket 3；
There are two the brackets 3 and arranged in parallel, and one is equipped on bracket 3 can measure the support of horizontal and vertical direction length
Frame 4；The cross bar 1 is connect by sleeve 2 with support frame 4；The cross bar 1, support frame 4 are equipped with scale, and support frame 4 is for reading
Height is taken, cross bar 1 is for reading length；The sleeve 2 is equipped with a vertical window, it can be seen that the scale on support frame 4, side
Just it reads.
Support frame as described above 4 and bracket 3 form T-type rigid fixation structure and cross bar 1 forms a set of clothes-horse form together
Overall structure.
The scale of one end that support frame as described above 4 is connect with bracket 3 is zero, and up reading is positive.
The sleeve 2 is movably fixed on support frame 4 by bolt, can according to need the height of adjustment sleeve 2.
The cross bar 1, sleeve 2, bracket 3, support frame 4 form an overall structure；Two support frames 4 are at work in
It is trapezoidal to stand on ground；Cross bar 1 is the biggish rigid rod of a rigidity.
The cross bar 1, sleeve 2, rigid movable connection between support frame 4, so that cross bar 1 can be arbitrarily flexible in the horizontal direction
Mobile, 2 can slide up and down on support frame 4, and two support frames 4 will not tilt and collapse when also may make work.
Embodiment
As described above, present apparatus test process is as follows:
When test, need inviscid coarse-grained soil specimen to be tested is piled to the coniform material of suitable size by code requirement
Heap is unfolded by the present apparatus, so that the distance between two support frames 4 are slightly larger than material heap diameter, cross bar 1 is highly slightly above material heap top
Portion is pushed into material heap from side by device, stands on two support frames 4 vertically on ground；Then the distance between two stands 3 is adjusted,
Keep 3 foot of bracket and material heap edge tangent, i.e. diameter of the distance between two stands 3 equal to material heap；The height for finally adjusting cross bar 1 makes
Itself and material heap tip contact.
The distance between two support frames 4, as the diameter D of material heap are read from cross bar 1 at this time, is read from support frame 4 horizontal
The height of bar 1, as the height H of material heap, then convert three different locations and measure D and H respectively, as shown in Fig. 2, be denoted as D1, D2,
D3 and H1, H2, H3, and the angle of repose α of surveyed coarse-grained soil specimen is calculated according to the following formula.
In conclusion using the present apparatus can the inviscid coarse-grained soil material heap diameter of rapid survey and height, it is at work, whole
What can be consolidated stands on ground, and the horizontal distance of two support frames, 4 staight scissors can arbitrarily change in 1 length range of cross bar, cross bar 1
Height can also arbitrarily be fixed on any position on support frame 4 by adjusting the bolt on sleeve 2.
