Description
Technical field
The utility model relates to a kind of earthwork test Instrument, espespecially a kind of full-automatic multi-functional soil test instrument.
Background technology
Two kinds of methods of the general employing of prior art, the one, utilize lever principle, by manually adding the mode of counterweight, sample is exerted pressure, manual read's note, Processing Test data; The 2nd, by boosting frame, piston, cylinder body, formed, adopt air pressure or hydraulic pressure to apply test pressure.The shortcoming that adopts counterweight to exert pressure: the one, manual operation, time-consuming, labour intensity is large, and test efficiency is low; The 2nd, human factor is many, affects experimental accuracy; The 3rd, limit by counterweight specification, cannot arbitrarily apply the gravity pressure of soil sample.The shortcoming that adopts air pressure (hydraulic pressure) mode to exert pressure: the one, support equipment is complicated, and pressure source noise is large, and energy consumption is high, and environment for use is restricted.The 2nd, many instruments can only apply identical test pressure, cannot apply to different soil samples different gravity pressures.
Utility model content
For solving the problems of the technologies described above, the utility model test figure of giving security is accurate, and test efficiency is high, can complete continuously, constant gradient or the loading of classification independence, and not need pneumatic supply or hydraulic power source.And for integrating traditional fixed, full-automatic multi-functional soil test instrument that precompressed is tested.
The utility model is a kind of full-automatic multi-functional soil test instrument, comprises boosting frame, load sensor, sample installation accessories, hoistable platform, electric pressing and Control & data acquisition system.Described load sensor is connected on boosting frame, and described sample installation accessories is arranged on hoistable platform, and is positioned at load sensor below.Hoistable platform is arranged on electric pressing top, carries out elevating movement under the driving of electric pressing, and described sample installation accessories is consolidation container or pre-pressure vessel.
Described pre-pressure vessel is comprised of pressure transmission plate, permeable stone, guide ring, guide frame, tank, and soil sample is between two permeable stones.
Useful technique effect of the present utility model is: 1, automatically to sample apply continuously, constant gradient or the loading of classification independence, automatically gather, Processing Test data, realized robotization.Compare with lever consolidometer, improved test condition, improved test efficiency.Avoid personal error, improved experimental accuracy; 2, adopt electric pressing, simple in structure.Compare with air pressure (hydraulic pressure) formula, need not piston, the optional equipment such as cylinder body and pressure source, realized device miniaturization, reduced the requirement to environmental baseline; 3, test pressure can be set arbitrarily within the scope of rated pressure, not only can meet the testing requirements of different soil properties, and can meet the testing requirements of different gravity pressures; 4, consolidation container is installed, can be carried out routine consolidation test; Pre-pressure vessel is installed, can be carried out precompressed test to soil sample, a tractor serves several purposes, reduces costs, and increases the benefit.
Accompanying drawing explanation

Fig. 2: consolidation container structural representation of the present utility model.
Fig. 3: precompressed structure of container schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model is a kind of full-automatic multi-functional soil test instrument, comprises boosting frame 1, load sensor 2, sample installation accessories 3, hoistable platform 4, electric pressing 5 and Control & data acquisition system.Described load sensor is connected on boosting frame, and described sample installation accessories is arranged on hoistable platform, and is positioned at load sensor below.Described hoistable platform is arranged on electric pressing top, carries out elevating movement under the driving of electric pressing, and the sample in sample installation accessories is exerted pressure.Because electric pressing can complete continuously, constant gradient or the loading of classification independence, and do not need pneumatic supply or hydraulic power source.Electric pressing can produce pulling force or compressive load.Compression system adopts closed-loop control, and test pressure can be set arbitrarily in rated range, and institute's plus-pressure size is measured by load sensor, and load sensor is connected with control, data acquisition system (DAS), automatically collection, deal with data.
Described sample installation accessories is consolidation container or pre-pressure vessel.Consolidation container as shown in Figure 2, soil sample 6 is arranged in tank 311, and the top of soil sample arranges pressure transmission plate 312.Pressure transmission plate is positioned at the below of load sensor 2.Consolidation container is installed, can be carried out routine consolidation test; Pre-pressure vessel as shown in Figure 3, is comprised of pressure transmission plate 321, permeable stone 322, guide ring 323, guide frame 324, tank 325.Soil sample 6 is arranged between upper and lower permeable stone.The pre-pressure vessel that accompanying drawing 2 is installed, can carry out precompressed test to soil sample, and a tractor serves several purposes, reduces costs, and increases the benefit.
Take precompressed test as example, before on-test, set the parameters such as testing load, test method, start thereafter electric pressing and start test.Hoistable platform rises, and under the effect of boosting frame counter-force, by 321 pairs of samples 6 of pressure transmission plate of sample installation accessories top, exerts pressure, and the water in soil sample 6 is discharged by permeable stone 322, and soil sample 6 produces fixed.Pressure size is measured by load sensor.In process of the test, according to set pressure, automatically stop loading, automatic decision is stable, automatic data collection, and whole process of the test is controlled automatically and is completed by microprocessor under unmanned condition.Routine consolidation test, sample is installed in consolidation container, and test method is tested with precompressed.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; the some improvement of electric pressing and modification can also be made to other pulling force or pressure apparatus, these improve and modification also should be considered as protection domain of the present utility model.
