Description
Technical field
The present invention relates to a kind of anti-disturbance sample erecting device, belong to indoor soil mechanics experiment field.
Background technology
Before the present invention, in the specimen of experiment installation indoors, typically rubber membrane is enclosed on outside sample with holding film cylinder, from
Suction hole air-breathing, be adjacent to film and hold film cylinder inwall, after by soil sample and hold film cylinder and be placed on base, upset rubber membrane lower end encases
Base, overturn rubber membrane upper end and remove and hold film cylinder, tightened sample bottom with elastic tape with film cylinder is held, in addition using split circle
Shape mold cramping sample, rubber membrane upper end inversion boot is held on film cylinder split, sample top cap, upset rubber membrane upper end bag are installed
Firmly top cap, film jacket casing will be held again and will tighten rubber membrane and top cap on sample, and with elastic tape.As can be seen here, traditional examination
In sample installation fixation procedure, holding film cylinder needs time that it is fixed on sample, and completes rubber membrane and base and top cap
Tighten work, therefore the device has following defect：1st, rubber membrane upper end is repeatedly stirred in sample installation process, these
Process can cause to disturb to soil sample, so influence soil sample related experiment accuracy, particularly with bury, silt soil,
The installation of the original state weakness soil sample such as muck soil, because the intensity of sample is relatively low, slight disturbance i.e. can to sample produce compared with
Big influence；2nd, said sample installation process is extremely cumbersome, operation inconvenience；3rd, whole operation process needs repeatedly fixed examination manually
Sample, operation difficulty is big, is unfavorable for the integrality of sample.
The content of the invention
In view of insufficient existing for background technology, the technical problems to be solved by the invention, which are to provide one kind, sample is existed
The disturbance to soil sample is reduced in installation process and sample installs easier anti-disturbance sample erecting device.
The present invention is adopted the following technical scheme that to complete：Anti- disturbance sample erecting device, it is characterized in that：Including top
Cap, rubber membrane, film cylinder, the first lock ring, the second lock ring, fixed mount and base are held, the film cylinder that holds divides film cylinder to be spliced into by more valves
Type simultaneously carries aspirating hole by the first lock ring banding, described hold on film cylinder, the base has upward lug boss, the fixed mount
By left fixed mount and right fixed mount spicing forming type and by the second lock ring banding, fixed mount is interior to carry inner chamber, the fixed mount lower end
With the lower jack that diameter and lug boss are close and matchs, what the fixed mount upper end approached with holding film cylinder and matched with diameter
Upper jack, the lower jack sleeve of the fixed mount are connected on the lug boss of base, described to hold the upper jack of film cylinder insertion and go deep into inner chamber
In, offered in fixed mount side wall and arrange hole, the film cylinder that holds is lined with the rubber membrane, and rubber membrane upper end is enclosed in top cap simultaneously
Tightened with elastic tape, lower end is enclosed on lug boss and is tightened with elastic tape.
Advantages of the present invention and effect：1st, the installation to sample be by more valves divide film cylinder form hold what film cylinder was carried out,
Repeatedly entangle sample and be fixed unlike needing to hold film cylinder in traditional test method and tighten work with elastic tape, can greatly reduce
The disturbance that soil sample is subject to；2nd, increase fixed mount and be supported fixation to holding film cylinder, and the arrangement hole of fixed mount sidepiece can be used for inciting somebody to action
Rubber membrane lower end is enclosed on the lug boss of base, is reduced because artificially repeatedly stirring disturbance of the rubber membrane to soil sample；3rd, tradition examination
Need film forming cylinder and split circular die supporting in sample installation, only need that more valves divide that film cylinder forms in the present invention holds film cylinder, right
Experimental rig has carried out simplifying optimization；4th, fixation of the fixed mount to sample is more firm during its experiment, can reduce people's reality
The operation that personnel fix manually is tested, reduces the operation difficulty of experimenter.Above-mentioned anti-disturbance sample erecting device is applicable to more
Kind laboratory soil test, such as triaxial test, resonant column test etc., both can effectively shorten the sample set-up time, and can subtracts significantly
Few manual operation disturbs to caused by soil sample, substantially increases test accuracy.
