Description
Technical field
The present invention relates to civil engineering soil test field, particularly relate to a kind of multi-joint reinvent saturated soil sample preparation device；Tool
Body relates to a kind of saturated reinventing fine grained soil sample preparation device for preparing, it is adaptable to the physico mechanical characteristic of research water soil chemical field
Prepared by test remoulded sample.
Background technology
In engineering practice, a series of laboratory test will be carried out in order to obtain the physical and mechanical parameter of the soil body.At present, room
The soil sample that interior test is used can be divided into undisturbed soil sample and indoor remoulded sample.Although undisturbed soil sample can reflect the soil body more truly
Prototype structure, but affected by restriction and the environment of sampling technique, its result of the test is unsatisfactory, and discreteness is bigger.On the contrary,
Indoor remoulded sample not only character is relatively uniform, experimental result discreteness is less, and the condition of sample is controlled, it is simple to specific
Experimental study；Therefore, the most selected at civil engineering soil test field manipulated soil.
Existing remoulded sample technology of preparing can be roughly divided into two classes:
1, compacting process, i.e. uses the weight of certain mass, a certain height fall, and one or more layers compacted soil samples is to required
Size, this method is simple to operate, and the sample preparation time is fast, but the density of soil sample prepared is uneven, and its underpart compaction rate is more than top；
2, concretion method, the thin mud that will stir pours sample preparation cylinder into, accelerates soil sample consolidate by adding static load, and this method can
Obtain the uniform soil sample of moisture content, effectively overcome the defect of compacting process.
At present, although having got well several by the manipulated soil sample preparation device of concretion method principle design, but still suffer from certain
Limitation.Such as, when indoor are by the control variate method research soil body and chemical solution interphase interaction, need to prepare dry density phase
With and the different remoulded sample of solution concentration or preparation solution concentration is identical and remoulded sample etc. that dry density is different, due to the soil body
Reaction with chemical solution is very slow, and January at least, at most several months, the most longer, the sample preparation cycle is considerably long.By existing system
Sampling device, if in order to shorten the sample preparation cycle, then needing to prepare to overlap sample preparation device more；And pressure to keep steady during whole
Fixed, hydraulic jack is not accomplished, preferable solution is exactly preloading.Large area soil is prepared under higher consolidation pressure
Sample, the weight of preloading is the biggest, very waste counterweight and dangerous and relatively costly, uneconomical.
Summary of the invention
The purpose of the present invention is that the shortcoming and defect overcoming prior art to exist, it is provided that one is multi-joint reinvents saturated soil
Sample preparation device, is particularly well-suited to that variable is many, the soil test of sample preparation cycle length.
In order to achieve the above object, the technical scheme is that
This device includes soil sample, brandreth, stock, hook, steel wire rope, sample preparation device and counterweight, and its annexation is:
At the rectangle steel plate being provided above with band circular groove of brandreth, sample preparation device is placed in circular groove；Rectangular
The right and left of shape steel plate is respectively arranged with quarter butt and fixed pulley thereof；Left surface at brandreth is provided with left cross bar, steel wire rope
One end is fixed on left cross bar；Right flank at support is provided with right cross bar, is provided with jaw on right cross bar, the right-hand member of stock
Connect with jaw；The other end of steel wire rope is connected with the middle-end of stock after sequentially passing through the fixed pulley of brandreth and sample preparation device, counterweight
Being carried on hook, the left end of hook and stock connects, and forms and loads sample preparation device and the structure of power transmission；
Sample preparation device includes cover plate, base, sample preparation cylinder, lower permeable stone, upper dankness stone, montant and cross bar；In sample preparation cylinder, from
Under to upper, base, lower permeable stone, soil sample, upper dankness stone, cover plate, montant and cross bar are sequentially connected with, the inwall of cover plate and sample preparation cylinder
Form being slidably matched of movement, form the structure to soil sample experiment.
Compared with prior art, the present invention has following advantages and a good effect:
1. lever principle and fixed pulley group is utilized the thin mud in sample preparation device to be applied vertical pressure, even if consolidating higher
Prepare large area soil sample under knot pressure, the most only need a small amount of counterweight, effectively prevent preloading expense counterweight and hidden danger；Separately
On the one hand, sample preparation device material uses lucite, processes relatively steel easy, and more resistant to corrosion.
2. simultaneously up to four sample preparation devices can be installed on brandreth, be largely that variable is many, the geotechnique of sample preparation cycle length
Test saves test period；And revise brandreth size slightly, more sample preparation device can be installed, for more multivariate, longer system
The facility that the soil test in sample cycle provides.
3. according to predetermined dry density, sedimentation value can be extrapolated, then set the bolt height at split round mould top, work as horizontal stroke
When bar sinks down into target sedimentation value, just supported, it is impossible to sink again, can be prepared by uniform, up to standard reinventing saturated soil sample,
Effectively reduce the labor intensity of personal monitoring's sedimentation.
The most whole sample preparation device has only to a set of loading system, for existing technology, effectively reduces cost,
There is preferable economic and practical.
