Description

Technical Field

[0001] The present invention relates to the field of geotechnical experiments, and in particular to a device for vibrating and crushing tests of completely weathered granite soil mass. Background Art

[0002] Currently, the existing crushing test devices can only perform displacement or pressure control and are not suitable for complex working conditions, such as crushing under the influence of vibration loads from trains, automobiles, etc.

[0003] There is a lack of a crushing device for completely weathered granite (soil mass) that can simultaneously consider the static and dynamic effects, and the crushing characteristics of completely weathered granite (soil mass) under complex working conditions cannot be studied.

[0004] More specifically, due to the oscillating load, the box body will be damaged, and the static pressure load cannot be applied if the box is shaking because the result is meaningless. Summary of the Invention

[0005] Purpose of the Invention: To provide a device for vibrating and crushing tests of completely weathered granite soil mass with better effects. The specific purposes can be seen in multiple substantial technical effects in the specific implementation part.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for vibrating and crushing tests of completely weathered granite soil mass, characterized in that the device includes a bottom foundation box 1, and the bottom foundation box 1 is square;

[0008] The bottom foundation box 1 is symmetrically provided with a pull-out gap 9, a track 16 is arranged in the pull-out gap 9, and it further includes a push slider 7 that can move along the track 16. The push slider 7 is provided with a push hole 8, an oscillating load providing device 6 is arranged on the push slider 7, an oscillating load providing spring 12 is arranged on the power shaft of the oscillating load providing device 6, and an oscillating load providing plate 5 is above the oscillating load providing spring 12; by pulling the push slider 7 in and out, the position of the oscillating load providing device 6 can be adjusted;

[0009] The four peripheries of the bottom foundation box 1 include a circle of oscillating springs 11, a material bearing plate 10 is fixed above the oscillating springs 11, the material bearing plate 10 is the bottom plate of a material bearing box 2, and materials can be placed in the middle of the material bearing box 2; it further includes a vertical load applying device 3 that can provide a pressure load to the material bearing box 2. The vertical load applying device 3 is arranged downward and extends with a load bearing plate 4, and the load bearing plate 4 can extrude the materials in the material bearing box 2;

[0010] There are plate fixing holes 14 arranged on the material bearing plate 10, and there are box fixing holes 15 arranged on the bottom foundation box 1. The plate fixing holes 14 and the box fixing holes 15 can be aligned and bolts are inserted for relative fixation.

[0011] A further technical solution of the present invention is that the load bearing plate 4 fits the inner wall of the material bearing box 2.

[0012] A further technical solution of the present invention is that the test device includes an oscillating load state. In this state, the pushing slider 7 is pushed into the drawing gap 9. The oscillating load makes the plate 5 closely adhere to the material bearing plate 10, and the oscillating load providing device 6 is started. The vertical oscillating load can oscillate the materials in the material bearing box 2; at this time, the plate fixing holes 14 and the box fixing holes 15 are disengaged from relative fixation, and at this time the oscillating spring (11) provides auxiliary vibration.

[0013] A further technical solution of the present invention is that the test device includes a direct pressure state. In this state, the plate fixing holes 14 and the box fixing holes 15 are fixed by bolts. At this time, the load bearing plate 4 provides a pressure load downward for a crushing experiment.

[0014] A further technical solution of the present invention is that there are oscillating state fixing holes 17 arranged on the pushing slider 7, and the wall corresponding to the drawing gap 9 includes box fixing holes 15. The pushing slider 7 can be relatively fixed by bolts passing through the oscillating state fixing holes 17 and the box fixing holes 15.

[0015] A further technical solution of the present invention is that the pushing slider 7 is pulled out in the direct pressure state.

[0016] A further technical solution of the present invention is that the track 16 is a T-shaped track.

[0017] A further technical solution of the present invention is that the vertical load applying device 3 is a hydraulic device.

[0018] A further technical solution of the present invention is that the oscillating load providing device 6 is an oscillating motor.

[0019] A further technical solution of the present invention is that the material placed in the middle of the material bearing box 2 is granite or granite soil mass.

[0020] The present invention adopting the above technical solutions has the following beneficial effects compared with the prior art: It should be known that in the past, the above two modes were in conflict, but with this patent, the two loads can be achieved simultaneously. There is a spring during oscillation and it can be fixed during extrusion, solving the problems of the current technology. Brief Description of the Drawings

[0035] It includes the following two modes:

[0036] The first one: The test device includes an oscillating load state. In this state, the pushing slider 7 is pushed into the drawing gap 9. The oscillating load makes the plate 5 closely adhere to the material bearing plate 10, and the oscillating load providing device 6 is started. The vertical oscillating load can oscillate the materials in the material bearing box 2. At this time, the plate fixing hole 14 and the box fixing hole 15 are disengaged from the relative fixation, and at this time, the oscillating spring (11) provides auxiliary vibration.

[0038] The substantial technical effects achieved by the technical solution here and its implementation process, that is, the basic functions, are as follows: It should be noted that in the past, the above two modes were conflicting, but with this patent, the two loads can be achieved simultaneously. There is a spring during oscillation and it can be fixed during extrusion.

[0039] Embodiment 2: As a further improvable solution or a parallel solution or an alternative independent solution, the load bearing plate 4 fits the inner wall of the material bearing box 2.

[0042] Embodiment 5: As a further improvable solution or a parallel solution or an alternative independent solution, the track 16 is a T-shaped track.

[0043] Embodiment 6: As a further improvable solution or a parallel solution or an alternative independent solution, the vertical load applying device 3 is a hydraulic device. The oscillating load providing device 6 is an oscillating motor. The material placed in the middle of the material bearing box 2 is granite or granite soil body.

[0044] It is possible to study the fragmentation characteristics of soil under complex loads (dynamic and static), overcoming the defect that existing particle fragmentation devices can only be controlled by displacement or pressure, which is of great significance for the study of the fragmentation characteristics of easily fragmented soils (such as completely weathered granite, crushed brick miscellaneous fill, etc.). Pioneeringly, the above effects exist independently and can also be combined by a set of structures to achieve the above results.

[0045] It should be noted that the multiple solutions provided by this patent include the basic solutions of themselves, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve the co-realization of multiple effects.
