In the continuous exploitation in mine, cause the ecological environment in colliery, stone pit and metal and nonmetal deposits mountain poor, open
The barren rock stockyard formed during adopting and refuse dump, owing to destroying original Soil structure, create the loose of many accumulations
Garbage, causes rock-mass relaxing, loose garbage to pile up instability, and mining area breaking topography phenomenon is serious, and avalanche easily occurs
With natural disasters such as landslides；Also can produce substantial amounts of soil erosion, cause vegetation deterioration, water body and heavy metal pollution.
Barren rock stockyard and refuse dump loose media size differ, and loose media platform is layered by transport dregs vehicle
Tamp, cause its soil layer construction unreasonable, bad hydraulic permeability, it is unfavorable for plant growing.Under soil compression, ventilating slit can be caused
Degree reduces, defective aeration, increases soil volume quality, reduces soil permeability, and these impacts are growth and development of plants
Unfavorable factor.Compacted soil makes resistance of soil and mechanical resistance substantially increase, and the supply of oxygen and water-holding capacity reduce, plant photosynthesis speed
Rate declines, and these factors cause pricking under root system of plant being obstructed.Research is how under the conditions of different-grain diameter and different number of machine passes etc.
Soil function and application the Different Ways of Planting impact on plant growing, finally determine the Soil structure of optimum plant growing
And compaction process, the compaction test research carrying out incompact-deposit bodies is particularly important.
Hit the real equipment Indoor Impaction Test mainly for roadbed material at present, measure compacting soil optimum moisture content and
Its bulk density, as building roadbed and the basis controlling soil moisture and appointment least density when banketing.Not for
Mine Abandoned Land incompact-deposit bodies carries out compaction test and the research of plant growing impact effect, be not suitable for big particle diameter (<
The mensuration of the Compaction after gangue materials 50mm) and mixing with soil.
Utility model content
The purpose of this utility model is, it is provided that a kind of compaction test apparatus, and this compaction test apparatus simple in construction is easy to use, it is simple to wild
Outer operation, using effect is good, accurate for experimental test result.
For reaching above-mentioned purpose, this utility model have employed following technical scheme:
A kind of compaction test apparatus, described compaction test apparatus includes that base 1, described base 1 center vertical arrange center-pole 2, described center
Bar 2 lower end is sheathed hits real part 3；Described center-pole 2 upper end arranges drawing piece 4, described drawing piece 4 be used for pulling hit real part 3 along in
Core bar 2 moves up and down.
Further, described compaction test apparatus also includes that sleeve 5, described sleeve 5 are used for holding and waits to hit matter in kind.
Preferably, bottom described sleeve 5, drainage tube 51 is set.
Preferably, described sleeve 5 is cylindrical.Those skilled in the art can also select other shapes as required, only
Want its shape being suitable for hitting real part.Described sleeve 5 can select different-diameter as required, such as 10cm, 30cm or
Person 50cm.
Preferably, hit real part 3 described in and include that cake 31 and slide cartridge 32, described cake 31 are fixed on slide cartridge 32 bottom, and circle
Cake 31 and slide cartridge 32 are set on center-pole 2.
Preferably, described drawing piece 4 includes the cross bar 41 arranged with center-pole 2, described cross bar 41 two ends in decussation
Being respectively provided with pulley 42, arrange pulling rope 43 through pulley 42, pulling rope 43 two ends are fixed on to be hit on real part 3, pulls pulling rope
43, can make to hit real part 3 and move up and down along center-pole.
It is further preferred that also set up handle 44 on described pulling rope 43, described handle 44 is used for pulling pulling rope 43.
The principle contrast of this utility model and light power pre-test compaction test apparatus, the former is to hold by hitting the existing ground of making an excessive case more excessive
Carry force value；The latter is then to need to obtain foundation bearing capacity original value.Compaction test apparatus of the present utility model can measure particle size range (<
Compaction test after gangue materials 50mm) and mixing with soil, measures its optimum moisture content and maximum dry density.
