Description
Technical field
The utility model relates to a kind of multi-functional sample preparation device that is applicable to soil body triaxial test, belong to soil test testing tool technical field.
Background technology
Triaxial test for the soil body, the different tests project often need adopt different samples, under the ordinary triaxial test, cylindrical sample is adopted in test, and for cohesive soil, mix the triaxial consolidation shearing test of gravel clay, because the cohesive soil infiltration coefficient is very low, draining is extremely slow, adopt conventional cylindrical sample, its test period is oversize, in order to shorten test period, need to adopt a kind of rapid triaxial test, the sample of rapid triaxial test is that the center is provided with the cylindrical sample (being called the sand-core cylinder sample) of being filled the cylindrical core that forms by sand grains.
More than in two kinds of samples, cylindrical sample can adopt existing standard sample preparation device to carry out sample preparation, the sand-core cylinder sample does not then have ready-made sample preparation device.The standard sample preparation device of existing cylindrical sample can not be used to make the sand-core cylinder sample, needs the sample preparation device of redesign and configuration sand-core cylinder sample; But it is cylindrical that two kinds of samples are, and its height, diameter dimension are all consistent, and the sample preparation device of sand-core cylinder sample must have many parts identical with cylinder sample sample preparation device, and repeated configuration then causes the wasting of resources.
Summary of the invention
The purpose of this utility model is to provide a kind of sample preparation device that can make cylindrical sample and sand-core cylinder sample simultaneously, can save resource, avoid sample preparation to think highly of composite putting.
The multi-functional sample preparation device that is applicable to soil body triaxial test comprises test specimen tube and hits sample device two parts.Test specimen tube comprises base, three-part pattern, lower clamp, upper clamp and casing; The test specimen tube base is provided with three-part pattern, and the three-part pattern outer lower portion has anchor clamps that base and three-part pattern are fixed together, and three-part pattern top is fixed by anchor clamps.Hit the sample device and comprise force transmitting board, compaction hammer, guide rod, stop; Guide rod is provided with compaction hammer, and the guide rod upper end is provided with stop.The test specimen tube base is two-sided base, and its edge is two-sided all the screw-type circular hole, and the base middle part is the circular fixed groove of the threaded type circular hole in center for circular fixed groove, another side simultaneously.Three-part pattern is 120 ° circular arc sheet metal by three central angles and forms.Lower clamp is an annular, and its edge has circular hole, can be fixed together with key screw base and three-part pattern by lower clamp; Upper clamp is a clamshell type, and two strip terminals place are with holes and connect with screw.Force transmitting board has two kinds, and a kind of is the sheet metal of the threaded circular hole of end face, another kind of sheet metal for the centre perforation.Guide rod is cylindrical straight-bar, and its bottom is threaded, and can be fixed together with the base of the threaded circular hole of hammer power transmission base plate or center of the threaded circular hole of end face.
The utility model has solved the problem that the sand-core cylinder sample does not have the sample preparation device, makes the sample preparation device can be applicable to the making of conventional cylinder sample simultaneously, has avoided the repeated configuration of different sample preparation devices a plurality of same parts, has effectively saved resource; In the sample making course of after this cylinder sample and sand-core cylinder sample, this sample preparation device is not only simple and direct in the use, is convenient to operation, has saved test period, has more reached good effect producing on cylinder sample even, up to standard and the sand-core cylinder sample.
