Description
Technical field
The utility model belongs to construction project technical field, relates to current velocity controller prepared by a kind of indoor sand sample, the current velocity controller of especially sand rain method sample preparation.
Background technology
According to the needs of engineering and scientific research, usually will do indoor sand model test, wherein the preparation of sand sample is important sport technique segment, and the quality of sample preparation directly affects the success or failure of sand model test.At present, prepare the method that sand sample often uses to have vibratory drilling method, compacting process, plug and pound method and sand rain method.Vibratory drilling method, compacting process can the sandy soils of simulate backfill, but it is often applied to the unit sample experiment such as sound three axle, Resonant Column, can not directly apply to large-scale model experiment; Sand rain method can be carried or the natural sand soil layer of current deposition by simulate wind, and its shaping sample is more close with actual natural layer of sand, and be convenient to application in large-scale model experiment, the method extensively adopts in all kinds of model tests of sand.But the flow velocity of the uncontrollable sand export of sand rain method sample preparation device in the past and uninterrupted, and along with the outflow of sand, in the collection sand device of upper end, sand face declines gradually, sand export flow velocity and flow change, cause preparing sand sample uneven, poor repeatability, is not well positioned to meet testing requirements.
Summary of the invention
Uneven deficiency is scattered in order to overcome existing sand rain method sample preparation device uncontrollable sand export flow velocity and uninterrupted, maintenance flow velocity and constant flow and sand.The utility model provides a kind of sand rain method current velocity controller, this current velocity controller can not only control sand export flow rate and uninterrupted, keeps constant flow rate, and makes sand scatter evenly, homogeneity and the good sand sample of repeatability can be prepared, improve sample quality.
The technical solution of the utility model is: a kind of sand rain method current velocity controller comprises: hose adapter, filter tip sheet, stucco cylinder, dispersion tube and screen cloth.Stucco cylinder is the uncovered cylinder in top seal, bottom, and has the circular hole being less than hose adapter internal diameter at its top; Hose adapter one end is connected and fixed with the flexible pipe that shakes out, and the other end is connected with stucco cylinder, and is placed on the circular hole at stucco cylinder top; The flexible pipe upper end that shakes out is connected with collection sand device; Place filter tip sheet between hose adapter and stucco cylinder, filter tip sheet is the perforated disk of band, and for changing the size of stucco flow velocity and flow, filter tip sheet perforation size is selected according to flow rates demand; Dispersion tube is the cylinder of open at both ends, and is provided with screen cloth at its two ends, and dispersion tube is placed in bottom stucco cylinder, wherein sieve mesh size according to needed for prepare the grain size of sand sample and select.
When using sand rain legal system for sand sample, the sand in the collection sand device of upper end flows downward, and flows through the flexible pipe that shakes out and arrives hose adapter inside; Through the control of filter tip film perforation eye size, sand enters in stucco cylinder with certain flow rate, scatters on the screen cloth at dispersion tube top; By the peptizaiton of screen cloth, sand enters dispersion tube inside, drops on the screen cloth of bottom, further by the dispersion of screen cloth, scatters out flow velocity and constant flow, uniform sand.
Effect of the present utility model and benefit are: device is simple, conveniently be connected with sand rain legal system sampling device, sand export flow velocity and uninterrupted can be controlled, keep stucco flow velocity and constant flow, and the sand of whereabouts can be disperseed, sand is scattered evenly, prepares homogeneity and the good sand sample of repeatability, improve sample quality.
Accompanying drawing explanation
Accompanying drawing is structure composition diagram of the present utility model.
In figure: 1 collection sand device; 2 shake out flexible pipe; 3 hose adapters; 4 filter tip sheets; 5 stucco cylinders; 6 screen clothes; 7 dispersion tubes; 8 model casings.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with technical scheme (and accompanying drawing).
In the accompanying drawings, collection sand device 1 and the flexible pipe 2 that shakes out all belong to a part for sand rain method sample preparation device; Stucco cylinder 5 is the uncovered cylinder in top seal, bottom, and has the circular hole being less than hose adapter 3 internal diameter at its top; The flexible pipe 2 that shakes out of hose adapter 3 one end and sand rain method sample preparation device is connected and fixed, and the other end is connected with stucco cylinder 5; Place filter tip sheet 4 between hose adapter 3 and stucco cylinder 5, filter tip sheet 4 is the perforated disk of band, and can change stucco flow velocity and uninterrupted, the size of filter tip sheet 4 eyelet is selected according to flow rates demand; Dispersion tube 7 is the cylinder of open at both ends, and at its two ends parcel screen cloth 6, entirety is positioned over bottom stucco cylinder 5, wherein screen cloth 6 mesh size according to needed for prepare the grain size of sand sample and select.
Concrete operation step: pour a certain amount of sand in collection sand device 1, when starting to prepare soil sample, sand flows downward, flows through the flexible pipe 2 that shakes out and arrives hose adapter 3 inside; Through the control of filter tip sheet 4 barrel hole size, sand enters in stucco cylinder 5 with certain flow rate, scatters on the screen cloth 6 at dispersion tube 7 top; By the peptizaiton of screen cloth 6, it is inner that sand enters dispersion tube 7, drops on the second layer screen cloth 6 of bottom, disperse further, scatter in model casing 8, prepares flow velocity and constant flow, uniform sand sample.
