Detailed description of the invention
As Figure 1-4, a kind of compaction test device preparing manipulated soil ring-shaped sample, including hitting real plate 1, guide post 2 and weight 3, the described reality plate 1 that hits includes low bottom-disc 4 and top bottom-disc 5, low bottom-disc 4 and top bottom-disc 5 are arc, width adapts with the width of ring specimen, are wherein provided with screwed hole 6 in the middle of top bottom-disc 5；Described guide post 2 include guide rod main body 7, guide rod main body 7 lower end be provided with match with screwed hole 6 thread segment 8, interlude is provided with scale 9, upper end is provided with handle 10, described weight 3 is enclosed within guide rod main body 7.
As it is shown in figure 1, the angle at sideline, described low bottom-disc 4 two ends and ring specimen center is 120 degree, top bottom-disc 5 is 60 degree with the angle at ring specimen center.
As it is shown on figure 3, described weight 3 is column.
As shown in Figure 4, described weight 3 is bow, about guide rod main body 7 centrosymmetry about bow.
As shown in Figure 5, on described guide post 2, guiding mechanism 11 is installed, guiding mechanism 11 includes cross bar 12, vertical pole 13, cross bar 12 one end is connected with guide rod main body 7, the other end is socketed with vertical pole 13 by sleeve, described vertical pole 13 is arranged on ring specimen center, and vertical pole 13 bottom is provided with that sucker 14 upper end is uniform is surrounded with three indicating arms 15.During hitting soil, after often having impacted once, need to rotate 120 degree of corners, density unevenness is caused for avoiding some position to be hit twice in the shots of a week, indicated by the indicating arm above guiding mechanism, make the angle turned in rotary course accurate, it is ensured that after rounding, ring specimen everywhere is all impacted once, so that it is guaranteed that density of soil sample uniformity consistency.
Operation principle and process:
1), according to the soil sample needed for testing program calculating, soil sample is put in the shear box of ring shear apparatus, and the surface of soil is patted whole.
2), hit actual load and put installation: weight 3 is threadeded with top bottom-disc 5 through guide rod main body 7, guide rod main body 7 lower end, and handle 10 is installed in upper end.
3), by this hit actual load and be placed in above soil layer, make low bottom-disc 4 contact with soil sample, and keep guide rod main body 7 vertical with soil sample top layer.
4), first, this is hit actual load and puts and rotate a circle, compacted samples under the conditions of it is conducted oneself with dignity；Then, being fallen by weight self-retaining high perpendicular, each hammering height can be controlled by the scale of labelling in guide rod main body, and every hammering the most just rotates once in the way of turning circle, to ensure soil sample compacting uniformly.Often soil sample being compacted one week, i.e. with vernier caliper measurement and calculate soil sample height, thus control density of soil sample, to reach requirement of experiment, prepared by sample.
5), after prepared by sample, ring shear apparatus shear box is arranged on ring shear apparatus device, after installing, checks that each component settings of ring shear apparatus device is the most correct, confirm errorless after, carry out the ring shear test work of manipulated soil according to the requirement of testing program.
