In civil engineering construction work, for the calculating analysis of soil body stability, shearing strength is that most important of which calculates ginseng
Number.Soil classifiction can be measured by direct shear test.
Existing making in laboratory staight scissors sample passes through artificial closely knit method, this traditional approach system usually using common cutting ring
The sample compactness of work is uneven, and the height and surface smoothness of sample are not easy to hold, and are difficult completely to take out from cutting ring,
Then easily cause experimental error.
The content of the invention
Technical problem to be solved in the utility model is to be directed to lacking for the existing method for making sample of indoor direct shear test
There is provided a kind of light-duty manipulated soil staight scissors sample making device for point.During using this instrumentation staight scissors sample, easy to operate, density is equal
Even, highly equal, surface is smooth, and dismounting sample is easy.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of light-duty manipulated soil staight scissors sample
Sampling instrument, it is characterised in that：Including pressure-like plug, left sample preparation base, right sample preparation base, circular steel plate, location-plate, hex bolts,
Hex nut；The left sample preparation base, right sample preparation base and location-plate are connected；The pressure-like plug include bail,
Limiting plate, pressure-like consolidation of cutting somebody's hair are connected；The pressure-like is provided with two steam vents beyond the Great Wall；The pressure-like room by pressure-like plug,
Left sample preparation base, right sample preparation base, the space of circular steel plate formation are constituted.
The internal diameter of pressure-like room cylindrical space is 61.8mm, is highly 20mm.
The pressure-like is cut somebody's hair as solid patty, and the diameter that pressure-like is cut somebody's hair is equal with the internal diameter of pressure-like room.
The circular steel plate is solid patty steel plate, and diameter is equal with the internal diameter of pressure-like room.
The left sample preparation base, right sample preparation base and the location-plate of both sides are integral type structure.
The beneficial effects of the utility model are：Staight scissors sample is solved by this sampling instrument and makes Density inhomogeneity, examination
The different shortcomings different with surface smoothness of the height of sample everywhere；Effectively control the density of staight scissors sample, the surfacing of sample
Degree, meets the related standard specimen required precision of direct shear test, easy to operate, installation and removal sample is simple；Pass through pressure
The steam vent of sample beyond the Great Wall can discharge the air in pressure-like room, solve the exhausting problem during sample makes；The circle of pressure-like room bottom
Steel plate prevents that the splicing due to sample preparation base from interfering to compacted soil samples, it is ensured that the integrality of soil sample.

Embodiment
A kind of light-duty manipulated soil staight scissors sample making device, it is characterised in that：Including pressure-like plug 1, left sample preparation base 2, right system
Sample base 3, circular steel plate 4, location-plate 6, hex bolts 7, hex nut 8；The left sample preparation base 2, right sample preparation base 3 are with determining
Position plate 6 is connected；The pressure-like plug 1 includes bail 13, limiting plate 9, pressure-like 10 consolidations of cutting somebody's hair and is connected；It is described
Two steam vents 11 are provided with pressure-like plug 1；The pressure-like room 5 is by pressure-like plug 1, left sample preparation base 2, right sample preparation base 3, circle
The space of the formation of steel plate 4 is constituted；Have on described left sample preparation base 2 and the alignment splicing of right sample preparation base 3, the location-plate 6 of both sides
Bolt hole 12, penetrates hex bolts 7 and tightens fixation by hex nut 8；The internal diameter in the cylindrical type space of sample preparation chamber 5 is
61.8mm, is highly 20mm；It 10 is solid patty that the pressure-like, which is cut somebody's hair, and pressure-like is cut somebody's hair 10 diameter and the internal diameter of pressure-like room 5
It is equal；The circular steel plate 4 is solid patty steel plate, and diameter is equal with the internal diameter of pressure-like room 5；The left sample preparation base 2, the right side
