Description

Liner tube type vertical compression undisturbed soil soil sample barrel
Technical field
The present invention relates to a kind of soil sample barrel, a kind of liner tube type vertical compression undisturbed soil soil sample barrel specifically, this soil sample barrel is used to gather the soil analysis sample of different depth, not being only applicable to scientific research undisturbed soil samples, also be applicable to soil test sampling, be suitable for and soil, geotechnological relevant scientific research, teaching and production division.
Background technology
Soil sample barrel gathers soil analysis sample as one, for soil analysis sampling, the aid of soil test sampling is by the scientific research relevant with it, teaching and production division are used widely, soil sample barrel of the prior art, the formerly patented claim that for example patent No. is 200410073303.2, because its structure is unreasonable, so there is many shortcoming and defect parts, be in particular in: 1., owing to adopting threaded drillpipe that soil sample barrel is pressed in soil, utilizing screw thread rotation pressure to promote soil sample barrel moves down, in folding process, soil sample barrel can not rotate with threaded drillpipe, so the plate that is pressed into of threaded drillpipe lower end is bearing, its anti-pressure ability is less, when threaded drillpipe is pressed into, easily pressure break bearing, affect its fetch earth degree of depth and scope that fetches earth, 2., soil sample overcoat press-in device design is unreasonable, a little less than anti-pressure ability, takes out difficulty after being pressed into soil.
Develop a new structure soil sample barrel in order to address the above problem applicant, and apply for utility model patent, the patent No. is 200920094990.4, this soil sample barrel is mainly used in gathering the topsoil soil sample of 20cm left and right, the section larger for the depth ratio that fetches earth fetches earth, as gather scientific research, teaching undisturbed soil and the soil test soil sample of deep layer more of 40cm-100cm, because manpower is limit, fetch earth more difficult.
Summary of the invention
The present invention seeks to provide a kind of simple and reasonable, easy to operate, time saving and energy saving, it is little that soil sample barrel enters soil layer resistance, utilizes lifting jack that soil sample barrel is pressed into the high-level efficiency liner tube type vertical compression undisturbed soil soil sample barrel in soil.
The object of the present invention is achieved like this, this soil sample barrel comprises soil sample barrel main body, is arranged on internal lining pipe and the block of soil sample barrel body interior, be arranged on the block of soil sample barrel main body upper end, be arranged on the A-frame above soil sample barrel main body, be arranged on the lifting jack between soil sample barrel main body and A-frame.
The soil sample barrel of described soil sample barrel main body comprises the section of fetching earth, bushing pipe canned paragraph and three parts of block canned paragraph, and the outside leading portion of the described section of fetching earth is that perpendicular cylinder, back segment are centrum shape, and the inside of the section of fetching earth is perpendicular cylinder; One end of the close section of fetching earth in outside of described bushing pipe canned paragraph, with an annular protrusion, is connected in a side of annular protrusion and the centrum shape of the section of fetching earth; Described bushing pipe canned paragraph is inner to be connected by a rounding off section with the section of fetching earth perpendicular cylinder.
Described internal lining pipe is arranged in the bushing pipe canned paragraph of soil sample barrel body interior, withstand in ring-type rounding off section, described in the internal diameter that fetches earth mouthful be less than the internal diameter of internal lining pipe.
Described block front end is cylindrical tube shape, and rear end is stiff end, and described block is made up of with the column type sleeve that is connected plate body the disc plate body of a side.
In the time that the degree of depth is fetched earth in increase, by realizing to pad pipe is set between A-frame and lifting jack.
The present invention, owing to plastic inner lining pipe being set in the inside of soil sample barrel main body, has overcome soil difficulty of soil sample barrel in prior art, and soil sample can not approach the shortcoming and defect of virgin state, and soil sample barrel is more convenient in the time fetching earth; Utilize lifting jack that soil sample barrel is pressed in soil, the outside annular protrusion of the section of fetching earth has reduced soil resistance, be beneficial to lifting jack soil sample barrel is pressed into soil, having overcome soil sample barrel in prior art, to enter the resistance of soil layer large, firming effort, and soil sample barrel takes out difficult shortcoming and defect from the soil body, it is simple and reasonable, time saving and energy saving to have, efficiency advantages of higher, is and soil, the relevant scientific research of geotechnique, teaching and production division gather pedotheque the first-selection of the carrying out soil sample analysis utensil that fetches earth.

Embodiment
Shown in accompanying drawing 1,2: this soil sample barrel comprises soil sample barrel main body 1, is arranged on internal lining pipe 2 and the block 3 of soil sample barrel main body 1 inside, be arranged on the block 4 of soil sample barrel main body 1 upper end, be arranged on soil sample barrel main body 1 A-frame 5 above, be arranged on the lifting jack 6 between soil sample barrel main body 1 and A-frame 5.
Shown in accompanying drawing 3,4: the soil sample barrel of described soil sample barrel main body 1 comprises the section of fetching earth 7, bushing pipe canned paragraph 8 and 9 three parts of block canned paragraph, one end of the close section of fetching earth 7 in outside of described bushing pipe canned paragraph 8 is with an annular protrusion 10, a side at annular protrusion 10 is connected with the centrum shape 11 of the end 7 that fetches earth, and described bushing pipe canned paragraph 8 is inner to be connected by a rounding off section 13 with the section of fetching earth 7 perpendicular cylinders.
Described internal lining pipe 2 is arranged in the bushing pipe canned paragraph 8 of soil sample barrel main body 1 inside, withstand in ring-type rounding off section 13, described in fetch earth mouthfuls 12 internal diameter be less than the internal diameter of internal lining pipe 2.
