Description
Technical field
Soil sample sample field is the utility model is related to, is cut more particularly to a kind of true triaxial test cube weak soil soil sample
Device.
Background technology
With the development in epoch, scientific and technological innovation, the research that Geotechnical Engineering subject is especially done in terms of weak soil research is got over
Come more accurate, but accurately one of instrument is exactly true triaxil tester, it be study weak soil property and mechanical response it is important
Technological means.When practical true triaxial instrument does weak soil testing experiment, it is necessary to weak soil is cut into cube, in order to true triaxial
Axially loaded plate and vertical load plate are with cube soil sample parallel contact, and otherwise test result will misalignment.True triaxial instrument pair
The cross sectional dimensions and longitudinal section flatness requirement of soil sample are very high, then now just need one kind to be applied to true triaxial test cube
Body weak soil soil sample cuts native device.
In the prior art, do when true triaxial test cuts soil sample, it is necessary to instrument be a finer wire, one ruler and
One set square, using ruler in the good size of the blank standard soil sample upper bottom surface amount i.e. cross section length of side fetched, then with cutting soil
Knife marks four diatoms respectively along measured four sides, and two terminals of every line fall on the circumference of blank soil sample upper bottom surface,
Just there are eight terminals so on circumference, the side of blank soil sample is leaned against with set square, respectively along eight points in side vertical
Eight lines are marked, the starting point of every line is the upper bottom surface of blank soil sample, and terminal is in bottom surface.Two people are finally needed to haul respectively
The four edges and side that the both ends of finer wire have measured along upper bottom surface pull line, move bottom to from top to bottom, such a
Cube soil sample is just cut.But the above method has disadvantages that, do not ensured that first when upper bottom surface measures four edges
The length of each edge reaches standard size.Next cannot guarantee that the interior angle of four edges reaches 90 degree, so be possible to make to cut
Soil sample out turns into four bank or ridge, rather than a cube, cannot guarantee that when testing load plate certainly and cuts
The good parallel contact of soil sample.3rd, two people are when hauling finer wire from top to bottom, due to the speed of two people's bracing wires
Difference and it cannot be guaranteed that the flatness hair of the longitudinal section for the soil sample that two people cut out along the line (deviations) pulled and making well
It is raw to destroy, it is possible to make longitudinal section outwardly convex or cave inward, it is also possible to make longitudinal section run-off the straight, the 4th, it is above-mentioned
Cutting indigenous method wastes time and energy, and cutting a soil sample at least needs half an hour.
Therefore, how a kind of simple in construction and precise and high efficiency true triaxial test cube weak soil soil sample cutter device is provided
It is the current technical issues that need to address of those skilled in the art.
