The utility model discloses can be applied to the experimental relevant parameter survey of maximum dry density (minimum hole than), through laying little modulus spring oscillator in a metal section of thick bamboo, the disturbance that is brought by the weight causes the spontaneous level of spring oscillator to the vibration, because of need vibrating tine and drive hammer simultaneous working when having solved the experiment, and must the above problem that could accomplish an experiment of two people.
Description
Technical field
The utility model belongs to the relative compaction determination techniques field of cohesiveless soil, more particularly to one kind measures inviscid
Native relative compaction laboratory apparatus.
Background technology
The most popular method that current China is not more than the cohesiveless soil of 5mm and energy free drainage for particle diameter is to hit manually
It is real.The instrument is difficult guarantee and drops hammer vertically in operation, cause hammer hit compaction cylinder mouthful experiment equipment is produced destroy and
Soil sample discontinuity causes to hit real not close phenomenon；The situation that casing and compaction cylinder often get stuck in experimentation, by force
Loosen compacted soil samples during extraction；Because needing vibrating tine and hammer to work simultaneously during experiment, then more than two people could must complete
One experiment, and increase experimenter's physical demands comparatively fast with number is hit, reduction hits actual effect really.
The content of the invention
The purpose of this utility model is to overcome prior art not enough, and purport is in a kind of measurement cohesiveless soil relative compaction of offer
Laboratory apparatus.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
One kind measurement cohesiveless soil relative compaction laboratory apparatus, including a support, are fixedly installed one on support
Handwheel and fixed pulley, are arranged with steel wire rope on handwheel, the free end of steel wire rope bypasses fixed pulley and is connected with a weight, weight
Bottom is provided with center identification；A base is provided with immediately below weight, the level(l)ing bubble for alignment, bottom are provided with base
A metal cylinder for containing cohesiveless soil is bolted to connection on seat, one is provided with metal cylinder internal base
Infrared collimater, the center identification of infrared collimator-alignment weight bottom；When using, cohesiveless soil is contained in metal cylinder, led to
Crossing operation handwheel makes weight that cohesiveless soil is hammered in metal cylinder.
Metal cylinder described in the utility model is double-decker, and spring has been radially arranged between inside and outside two-layer.
Metal cylinder inwall described in the utility model is provided with graduation mark.
Weight described in the utility model is high density cylinder iron hammer.
Compared with prior art, the beneficial effects of the utility model are：
The relevant parameter that the utility model can be applied to maximum dry density (minimum void ratio) experiment is determined, by metal
Small modulus spring oscillator is laid in cylinder, triggers spring oscillator spontaneous level to vibration from the disturbance that weight brings, solve experiment
Shi Yinxu vibrating tines and hammer work simultaneously, it is necessary to more than two people could complete a problem for experiment；
By the reading for inner tube wall high scale, realize can soil sample volume reading at any time, without compaction cylinder and
The combining structure of casing fixes volume of sample, therefore avoids the situation that casing and compaction cylinder in experimentation get stuck；
Ensure that impact each time in experimentation is all absolute upright, be it also avoid using the structure of vertical silk suspention weight
Hammer is caused to hit destruction of the compaction cylinder mouthful for experiment equipment because hammer seat is not disposed vertically；
The regulation that weight passes through jib-length and handwheel radius, adjusts the relative ratio of the arm of force, reaches labour-saving effect.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is metal cylinder structural representation.
Specific embodiment
Make the description into the utility model with specific embodiment below in conjunction with the accompanying drawings：
Such as Fig. 1,2, one kind measurement cohesiveless soil relative compaction laboratory apparatus, including metal cylinder 1, weight 2, base 3, spiral shell
The technical characteristics such as bolt 4, level(l)ing bubble 5, spring 6, infrared collimater 7 and handwheel 8.
One kind measurement cohesiveless soil relative compaction laboratory apparatus, including a support, are fixedly installed one on support
Handwheel and fixed pulley, are arranged with steel wire rope on handwheel, the free end of steel wire rope bypasses fixed pulley and is connected with a weight, weight
Bottom is provided with center identification；A base is provided with immediately below weight, the level(l)ing bubble for alignment, bottom are provided with base
A metal cylinder for containing cohesiveless soil is bolted to connection on seat, one is provided with metal cylinder internal base
Infrared collimater, the center identification of infrared collimator-alignment weight bottom；When using, cohesiveless soil is contained in metal cylinder, led to
Crossing operation handwheel makes weight that cohesiveless soil is hammered in metal cylinder.
Metal cylinder is double-decker, and spring has been radially arranged between inside and outside two-layer.The spring being radially arranged can reduce weight
The disturbance that hammer hammering brings.
Metal cylinder inwall is provided with scale, is easy to accurate measurement to contain the cohesiveless soil amount in metal cylinder.
Weight is high density cylinder iron hammer.
The method for measuring cohesiveless soil relative compaction, comprises the following steps：
A, by metal cylinder 1 and base 3 by three bolt connections and by spirit level leveling；
B, the relative position for placing metal cylinder 1 and weight 2, that is, open infrared collimater 7, is directed at weight center identification；
C, take 4000g air-dry or drying cohesiveless soil soil sample, be divided into two parts of uniform equivalent；
D, take a copy of it, be divided into three layers and pour into metal cylinder 1, every layer is poured into soil amount and is about 600-800g, with hairbrush or
Hand comforts to level of approximation soil sample；
E, shake weight 2 make cylindrical weight lifting to peak, and impact sample table is freely fallen with 30-60 times/min
Face.Impact repeatedly, vibration 5-10min is typically needed, untill the volume of sample no longer changes；
F, second, third time dress sample, repeat the step of d, e two；
G, the reading inner tube wall scale of metal cylinder 1, must hit soil sample volume after reality；
H, three layers impact after, bolt between metal cylinder 1 and base 3 is unclamped, soil sample is weighed in the lump together with metal cylinder 1,
After deducting compaction cylinder quality, according to soil sample volume and quality, the maximum dry density and minimum void ratio of soil sample are calculated；
I, portion soil sample repeat step d-h in addition is taken, carry out parallel determination.
Above-mentioned steps a spirit level leveling, it is therefore an objective to stand vertically metal cylinder 1, it is ensured that weight falls rear compacted soil samples water
It is flat.
Above-mentioned steps b is infrared, and collimater 7 is aligned, it is therefore an objective to make the center of metal cylinder 1 and weight center superposition, it is ensured that hit real point
In cylinder.
Above-mentioned steps i parallel tests, it is therefore an objective to exclude experiment contingency, if taken when result of the test is more or less the same twice compared with
Big value；Need to test again if the difference of result of the test twice is larger.
The undeclared part being related in the utility model is same as the prior art or is realized using prior art.
