Abstract

A kind of penetration type soil sample barrel of improvement, relate to a kind of soil sample barrel of geotechnical investigation, the utility model be to solve existing soil sample barrel injection and on carry in process, and the problem of the larger rubbing action existed between surrounding soil, thus reduce the level of disruption of soil sample, reduce the distortion of soil sample, improve the quality fetched earth.Soil sample barrel comprises sampler barrel, cutting ring head, sampler barrel is threaded connection cutting ring head, described sampler barrel lower end is provided with screw thread, end, described cutting ring head upper end is provided with screw thread, cutting ring head lower end outside surface is provided with ring-type domatic flange and ring-type arc convex, and cutting ring head inside is provided with flexible springs pull bar and rotatable support bar.The utility model is used for the sampling of on-the-spot undisturbed soil.

Description

A kind of penetration type soil sample barrel of improvement
Technical field
The utility model relates to a kind of soil sample barrel of geotechnical investigation.
Background technology
Soil sample barrel is applied widely in Geological Engineering and Geotechnical Engineering field.The level of disruption relation that the accuracy of the Soil Parameters that laboratory soil test provides is subject to soil sample is very large.
Penetration type soil sample barrel causes comparatively large disturbances when injection stratum to the soil body, simultaneously penetration type soil sample barrel in soil layer circumgyration incision, on when putting forward soil sample, the disturbance of soil sample tension, specimen deformation is serious, can not meet the high request to quality of soil sample in engineering, thus soil body physical and mechanical parameter accurately can not be obtained.
Utility model content
The utility model to solve the existing penetration type soil sample barrel problem larger to soil sample disturbance, provides a kind of penetration type soil sample barrel of improvement.
The penetration type soil sample barrel of a kind of improvement of the utility model comprises sampler barrel, cutting ring head, sampler barrel is threaded connection cutting ring head, described sampler barrel lower end is provided with screw thread, end, described cutting ring head upper end is provided with screw thread, cutting ring head lower end outside surface is provided with ring-type domatic flange and ring-type arc convex, and cutting ring head inside is provided with pull bar and support bar.
Described cutting ring head lower end outside surface is provided with ring-type domatic flange.
Described cutting ring head lower end outside surface is provided with ring-type arc convex.
Described pull bar is flexible springs pull bar, and it is 2 right that quantity is at least.
Described support bar is rotatable support bar, and it is 2 right that quantity is at least.
The beneficial effects of the utility model:
Cutting ring lower end outside surface described in the utility model is provided with ring-type domatic flange and ring-type arc convex, when injection and upper earth extracting device, can reduce the surface of contact of sampler barrel outside surface and soil layer, reduces soil sample disturbance.
Cutting ring head inside described in the utility model is provided with flexible springs pull bar and rotatable support bar, and during injection soil sample barrel, spring pull bar compresses, and during upper earth extracting device, spring pull bar stretches, and support bar cuts and holds up soil sample, reduction soil sample is proposed the disturbance in process.
The utility model effectively can reduce the disturbance of penetration type soil sample barrel to soil sample.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment one: composition graphs 1 illustrates present embodiment, the penetration type soil sample barrel of a kind of improvement of present embodiment comprises sampler barrel 1, cutting ring head 3, sampler barrel 1 is by screw thread 2 abutment ring cutter head 3, described sampler barrel 1 lower end is provided with screw thread 2, end, described cutting ring head 3 upper end is provided with screw thread 2, cutting ring head 3 lower end outside surface is provided with flange 5 and projection 4, and cutting ring head 3 inside is provided with pull bar 6 and support bar 7.
Embodiment two: present embodiment and embodiment one difference are: described cutting ring head lower end outside surface is provided with ring-type domatic flange.Other are identical with embodiment one.
Embodiment two: present embodiment and embodiment one difference are: described cutting ring head lower end outside surface is provided with ring-type arc-shaped protrusions.Other are identical with embodiment one.
