Abstract
The invention belongs to the technical field of sample soil sampling equipment, and especially relates to a tri-axial sample compression soil sampler. The tri-axial sample compression soil sampler is characterized in that the tri-axial sample compression soil sampler comprises an outer support frame, an inner support frame arranged in the outer support frame, a group of symmetrically-arranged sampling cylinders connected with the inner support frame, a support boot in threaded connection with a support leg at the bottom of the outer support frame, and a group of sampling cylinder boots in threaded connection with the bottom of the group of the sampling cylinders. The tri-axial sample compression soil sampler has the advantages of simple structure, low cost and use convenience. Specifications of onsite-taken samples satisfy test requirements, and test can be immediately carried out after the samples are sent to a laboratory, so operation reduction, construction period shortening and cost saving are realized.

Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of frame boots of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present invention.
As shown in Figure 1, 2, three axial compression contracting sample soil sample barrels of the present invention, it is characterized in that comprising outer support frame, be located at the inner support frame in this outer support frame, one group of sampler barrel 10 that inner support frame is connected and is arranged symmetrically with therewith, the frame boots 6 that are threaded with described outer support frame bottom shelf pin 13, the one group of sampler barrel cylinder boots 12 being connected with described one group of sampler barrel 10 bottom thread
Described outer support frame comprises one group of pillar 5, connects the collar tie beam 4 of this group of pillar 5, is located at the frame head 3 at described one group of pillar 5 intersection tops, is located at this one group of connecting hole 2 on 3, and this connecting hole 2 is in order to connect drilling tool and to match with existing general drilling tool,
Described inner support frame comprises through described 3 and the middle axostylus axostyle 7 that is threaded with bar head 1, the one group of upper strata sampler barrel pipe box 9 being connected with described middle axostylus axostyle 7 by connecting link 8, the Yi Zu lower floor sampler barrel pipe box 11 being connected with described middle axostylus axostyle 7 by connecting link 8, the top of one group of described sampler barrel 10 is threaded with corresponding described one group of upper strata sampler barrel pipe box 9, and the bottom of one group of described sampler barrel 10 is threaded with one group of described sampler barrel cylinder boots 12 through corresponding described Yi Zu lower floor sampler barrel pipe box 11.
Described sampler barrel 10 is comprised of two opposite opened semicanals.Sampler barrel 10 inside diameter must meet relevant native test sample geomery requirement in < < triaxial compression test > >.
Described frame boots 6 lower ends and the center of circle by described boots 6 are provided with cuts native cutter 14, the outside, lower end of described frame boots 6 is uniclinal declivous cutting edge, while fetching earth to facilitate, sting underground layer, reduce soil layer resistance, alleviate the disturbance to soil sample, by frame boots 6 centers of circle, lower end, be provided with and cut native cutter 14, after rotating to an angle, can cut off contacting between the soil body and the bottom soil body in soil sample barrel, the success ratio that fetches earth is high.
