Description

Detachable undisturbed sample geotome

Technical Field

The utility model relates to a geotechnical test, concretely relates to detachable original state appearance geotome.

Background

In the geological exploration process, in order to master the physical and mechanical characteristics of the building soil body, the soil body needs to be taken out and conveyed to a laboratory for testing. In the process, the soil sample is inevitably disturbed, so that the final test result cannot reflect the real condition of the soil body. In order to reduce the disturbance to the soil sample, it is necessary to develop advanced sampling equipment and mature sampling methods.

At present, cutting rings are mostly adopted for soil sampling, because the cutting rings are small in size and poor in sampling representativeness, soil bodies are easy to break when taken out of the cutting rings, the cutting rings are very easy to be affected by broken stones and grass roots when used for soil sampling, soil sampling efficiency is low, and accordingly test results are not true.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that it is great to the disturbance of soil sample to current geotechnological sample, the poor problem of sample representativeness provides one kind to the disturbance of soil sample less, simple structure, accomodate convenient detachable original state appearance geotome.

The utility model discloses the technical scheme who adopts is: a detachable undisturbed sample sampler comprises a plurality of upright posts arranged on the periphery of the sampler, wherein the top ends of the adjacent upright posts are hinged with a first cross rod, guide rails are oppositely arranged on the adjacent upright posts, a first guide groove which is communicated up and down is arranged on the first cross rod, a first soil cutting knife is arranged on the guide rail adjacent to the upright posts in a sliding manner, and the top of the first soil cutting knife is inserted into the first guide groove; the bottom ends of the parts of the adjacent vertical rods are movably connected with a second cross rod, a second guide groove which is through from inside to outside is formed in the second cross rod, and a second soil cutting knife is inserted in the second guide groove.

The utility model discloses after the geotome is got, when taking out the soil sample from the geotome, can cut native sword and second horizontal pole with first, two earlier and dismantle, then take out pole setting and first horizontal pole and can follow the geotome and take out the soil sample again, therefore the disturbance to the soil sample is few, can not influence the test result basically. Additionally, the utility model is not only simple in structure, the pole setting forms with first horizontal pole is articulated moreover, and first, two soil cutters and second horizontal pole can be dismantled, accomodate the convenience.

In order to facilitate pressing of the vertical rod into a soil layer, the bottom of the vertical rod is arranged to be in a pointed conical shape.

The upright rod is connected with the first cross rod through a spherical hinge.

In order to facilitate the stripping and taking out of the soil block, the opening of the bottom cutting edge of the first soil cutting knife is arranged outwards.

The utility model discloses a concrete embodiment does, the pole setting is four, arranges respectively the four corners of geotome, four first soil cutters set up respectively adjacently in the pole setting, a second soil cutters sets up on the second horizontal pole.

The utility model discloses simple structure, easily operation adopts earlier fixed soil sample, cuts again, and the mode of protection at last has reduced the disturbance to soil sample effectively, because its first, two cut native sword and second horizontal pole all can dismantle, and is more convenient when accomodating and carrying.

The utility model discloses be particularly useful for the particle diameter is thinner, and intensity is lower, the great weak soil of moisture content.

In the figure: the soil cutting machine comprises a vertical rod 1, a first cross rod 2, a first soil cutting knife 3, a second soil cutting knife 4, a spherical hinge 5, a second cross rod 6, a guide rail 11, a first guide groove 21 and a second guide groove 61.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1-5, the utility model discloses detachable original state appearance geotome embodiment one sets up four pole settings 1 in geotome periphery four corners, but the articulated first horizontal pole 2 of spherical hinge 5 that can free rotation is passed through on the top of adjacent pole setting 1, sets up four first horizontal poles 2 altogether. The adjacent vertical rods 1 are oppositely provided with guide rails 11, and the first cross rod 2 is provided with a first guide groove 21 which is vertically penetrated. The guide rail 11 of the adjacent vertical rod 1 is provided with a first soil cutting knife 3 in a sliding manner, and the top of the first soil cutting knife 3 is inserted into the first guide groove 21. The bottom ends of the adjacent vertical rods 1 are movably connected with a second cross rod 6, a second guide groove 61 which is through inside and outside is formed in the second cross rod 6, and a second soil cutting knife 4 is inserted into the second guide groove 61. In the embodiment, four first soil cutting knives 3 and one second soil cutting knife 4 are arranged.

In order to facilitate pressing of the vertical rod 1 into a soil layer, the vertical rod 1 is made of steel, and the bottom of the vertical rod 1 is in a pointed conical shape.

The first and second cross bars 2, 6 are made of the same material as the vertical bar 1. The first cross rod 2 and the second cross rod 6 have six members, and the six members and the vertical rod 1 act together to ensure that the soil sampler is firm and stable. The second cross rod 6 is arranged at the bottom end of the outer vertical rod 1 after the outer soil body is stripped.

In order to facilitate the stripping and taking out of the soil block, the opening of the bottom cutting edge of the first soil cutting knife 3 is arranged outwards. The first and second soil cutting knives 3 and 4 need to be coated with vaseline before sampling, so that disturbance to soil is reduced.

The spherical hinge 5 needs to be frequently coated with lubricating oil to ensure that the upright rod 1 and the first cross rod 2 can rotate freely.

The utility model discloses detachable original state appearance geotome can be processed into different sizes according to actual need.

During specific implementation, the surface layer floating soil and the grass and trees are cleaned at the position needing sampling, the outer vertical face of the sampling position is exposed, the upright rods 1 and the first cross rods 2 are opened to enable the equipment to be firm and stable, the upright rods 1 are lightly pressed into the soil, the first soil cutting knives 3 are sequentially arranged between the adjacent upright rods 1, the first soil cutting knives 3 are sequentially pressed down to the bottom end to enable the inner soil body to be slightly stripped, the two second cross rods 6 are sequentially arranged between the outer upright rods 1, the second soil cutting knives 4 are further arranged, and the second soil cutting knives 4 are pressed in, so that soil sample cutting is completed.

The above description is only for the preferred embodiment of the present application and should not be taken as limiting the present application in any way, and although the present application has been disclosed in the preferred embodiment, it is not intended to limit the present application, and those skilled in the art should understand that they can make various changes and modifications within the technical scope of the present application without departing from the scope of the present application, and therefore all the changes and modifications can be made within the technical scope of the present application.
