Description

A kind of soil sample compaction test manufactures the instrument on coarse soil top layer
Technical field
The utility model belongs to the mechanical test field of geomaterial, it relates to a kind of soil sample compaction test manufactures the instrument on coarse soil top layer.
Background technology
When carrying out the research of the problems such as the Calculation on stability of the earth structure such as earth dam, side slope under quiet power and dynamic condition, earth pressure problem and bearing capacity of foundation soil, need the mechanics index of physics measuring the quiet power of soil sample and kinematic behavior, triaxial compression test and dynamic triaxial test are the routine tests measuring the quiet power of soil sample and kinematic behavior mechanics index of physics, and the cylindrical sample of preparation 3 to 4 proterties equal is tested usually. Therefore, the preparation of soil sample is the basis of success of the test.
At present, the preparation of soil sample generally adopts layering dress sample, layering hits real method, the soil sample compaction test apparatus that laboratory widely uses, and is be made up of components such as weight, tail rod and base plates. Embodiment is: hand-held weight arrives certain altitude so that it is free-falling, and weight base plate reaches the object of soil sample compacting, before carrying out subsoil dress sample, it is necessary to little iron shovel, the surface of sample is shoveled into uneven surface, then carry out the dress sample process of subsoil. But the process making uneven surface is random, causes the degree of roughness of every layer of soil sample contact surface not identical, and then causing the defect of different interface strength inequality one, the sign when result tested and soil sample being destroyed causes impact to a certain degree.
Summary of the invention
The technical problems to be solved in the utility model is to provide the instrument that a kind of soil sample compaction test manufactures coarse soil top layer, it is possible to each layering in the preparation of each soil sample is made the soil layer surface of identical roughness, makes each soil layer interface strength even.
In order to solve the problem, the technical solution of the utility model is: a kind of soil sample compaction test manufactures the instrument on coarse soil top layer, comprise base plate, revolving bar, tail rod and compaction hammer, a threaded pipe connecting of inner tool it is connected with at the middle part of base plate, it is provided with screw thread in one end of tail rod, tail rod is threaded with pipe connecting, the first through hole it is provided with in the middle part of compaction hammer, compaction hammer is socketed on the guide bar by the first through hole, it is provided with scale marks on the guide bar, it is provided with the 2nd through hole away from one end of pipe connecting at tail rod, revolving bar is placed in the 2nd through hole, on the end face of base plate, distribution is installed with multiple projection.
Further, the shape of described projection is cone.
The novel technique effect of the utility model is: soil layer is being hit real after, use the utility model to be hit on soil layer surface to beat, hit beat process in utilize scale marks ensure compaction hammer falling bodies height consistent, make the degree of depth of protruding embedding soil layer identical, utilizing revolving bar to rotate protruding, the protruding surface producing identical roughness on soil layer surface, makes each soil layer interface strength even, the utility model is easy to operate, and structure is simple.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is perspective view of the present utility model,
Fig. 2 is schematic front view during of the present utility model use,
Fig. 3 is schematic front view during of the present utility model use.
Embodiment
If Fig. 1 is to shown in 3, a kind of soil sample compaction test manufactures the instrument on coarse soil top layer, comprise base plate 1, revolving bar 4, tail rod 2 and compaction hammer 3, a threaded pipe connecting 11 of inner tool it is connected with at the middle part of base plate 1, it is provided with screw thread in one end of tail rod 2, tail rod 2 is threaded with pipe connecting 11, the first through hole 31 it is provided with in the middle part of compaction hammer 3, compaction hammer 3 is socketed on tail rod 2 by the first through hole 31, tail rod 2 is provided with scale marks 5, it is provided with the 2nd through hole 21 away from one end of pipe connecting 11 at tail rod 2, revolving bar 4 is placed in the 2nd through hole 21, on the end face of base plate 1, distribution is installed with multiple protruding 6.
Further, the described shape of protruding 6 is cone.
Using method of the present utility model: as shown in Figures 2 and 3,
The first step, methods according to points of 3 layers dress sample, first fetch soil sample 8 and be put in as the first layer soil in dress sample cylinder 7, and by smooth for the surface treatment of soil sample 8.
2nd step, piece bottom surface of fetching do not have the optical substrate 12 of protruding 6, tail rod 2 and optical substrate 12 are screwed, and it is pressed in soil sample 8, keep tail rod 2 vertical with soil sample 8, compaction hammer 3 slides into level altitude and falls along the axes normal of tail rod 2, the each hammering height of compaction hammer 3 controls by the scale marks 5 on tail rod 2, and requires that limit hammering, limit are rotated without protruding 6 optical substrates 12 in the way of turning circle.
3rd step, utilizing optical substrate 12 soil sample 8 hit real after, under optical substrate 12 is revolved from tail rod 2, change and there is protruding base plate 1, the one side that base plate 1 has protruding 6 is pressed in soil sample 8, and compaction hammer 3 vertically falls after moving to level altitude, carries out hammering to having protruding base plate 1, protruding 6 are forced to be embedded in soil sample 8, then revolving bar 4 is inserted in the 2nd through hole 21, hold revolving bar 4 and rotate a circle, utilize protruding 6 to produce a coarse top layer to soil sample 8 surface.
4th step, on the first layer soil, spread second layer soil, repeat the above-mentioned the first step to the 3rd step, second layer soil is hit real and manufacture the operation of coarse top layer, finally spread third layer soil, utilize optical substrate 12 that third layer soil hits practical operation to do, prepared by so far test soil sample.
