Abstract
The utility model relates to the technical field of engineering geological investigating technical equipment, and discloses a ring soil sampler with thin-walled extension of shoe. The ring soil sampler comprises a catcher, a piston, a surplus soil tube and a soil sampling tube, wherein the catcher and the piston are mutually connected; the catcher is used for pulling up the piston; the surplus soil tube is arranged at the upper part of the soil sampling tube; the internal diameter of the shoe of the soil sampling tube with thin-walled extension of shoe is the same as the external diameter of a cutting ring; and the cutting ring is built-in the soil sampling tube. The ring soil sampler with thin-walled extension of shoe has the advantages of simple structure, convenient use, easy maintenance, and capability of easily and successfully sampling I stage undisturbed soil sample required by non-static and dynamic triaxial tests.
Description
Technical field
The utility model relates to the technical field of engineering geological investigation technical equipment aspect, particularly relates to the technical field of the equipment aspect that undisturbed soil fetches earth.
Background technology
Undisturbed soil is exactly the intact soil of structure, and manipulated soil is the random perturbation to undisturbed soil.To test and test the structure of undisturbed soil, only get undisturbed soil.Nation-building portion has made relevant requirement to the undisturbed soil technical standard of having taken a sample out to the sampling of undisturbed soil, and existing sand extractor structure does not meet gathers I level undisturbed soil sampling device technical standard.
Creeping into boring in the pure mine tailing layer of sand of loosely organized nothing gluing very easily caves in, the easy disturbance of taking a sample, sampling back testing laboratory can't the secondary sample preparation, and existing cutting ring sand extractor has solved the problem that sand sample does not need the secondary sample preparation, but structure does not meet " undisturbed soil sampling technique standard " requirement.
The utility model content
The utility model purpose aims to provide a kind of bundle joint formula cutting ring soil sample barrel, can successfully collect non-quiet, the moving needed I level of triaxial test undisturbed soil.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bundle joint formula cutting ring soil sample barrel, comprise catcher and piston, catcher is connected with piston, draw piston on the catcher, described bundle joint formula cutting ring soil sample barrel comprises Yu Tuguan and the pipe that fetches earth, and the pipe top of wherein fetching earth is Yu Tuguan, described bundle joint formula fetch earth the pipe shoe internal diameter be consistent with the cutting ring external diameter, cutting ring is built in the pipe that fetches earth.
Bundle joint formula cutting ring soil sample barrel, this bundle joint formula cutting ring soil sample barrel is provided with puts ring.
Described bundle joint formula cutting ring soil sample barrel, this bundle joint formula cutting ring soil sample barrel is provided with the cutting ring bulldozing device.
Described bundle joint formula cutting ring soil sample barrel is provided with shadoof between this bundle joint formula cutting ring soil sample barrel catcher and the piston.
Described bundle joint formula cutting ring soil sample barrel, the Yu Tuguan of this bundle joint formula cutting ring soil sample barrel is provided with vent port.
The utility model beneficial effect
This bundle joint formula cutting ring soil sample barrel is applicable to that boring takes to carry out the required I level original state sample of non-quiet, moving triaxial test test in the glued pure mine tailing layer of sand of loosely organized nothing.The more important thing is that to us the prospecting on mining tailing wasteland and similar stratum later on provides reliable sampling technique means.This bundle joint formula cutting ring soil sample barrel is simple in structure, easy to use, is easy to safeguard, is easy to success and takes non-quiet, the moving needed I level of triaxial test original state sample.
Description of drawings
The structural representation of Fig. 1 bundle joint formula cutting ring soil sample barrel
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, a kind of bundle joint formula cutting ring soil sample barrel mainly comprises catcher 1, shadoof 2, piston 3, surplus soil pipe 4, the pipe 5 that fetches earth, shoe 7, cutting ring 6, puts ring and form.Comprise catcher 1 and piston 3, catcher 1 is connected with piston 3, draws piston 3 on the catcher 1, described bundle joint formula cutting ring soil sample barrel take over 1 and piston 3 between be provided with shadoof 2.Described bundle joint formula cutting ring soil sample barrel comprises the surplus soil pipe 4 and the pipe 5 that fetches earth, and pipe 5 tops of wherein fetching earth are surplus soil pipe 4, and the Yu Tuguan of this bundle joint formula cutting ring soil sample barrel is provided with vent port; The fetch earth internal diameter of pipe shoe of described bundle joint formula is consistent with cutting ring 6 external diameters, and cutting ring 6 is built in to fetch earth manages 5.This bundle joint formula cutting ring soil sample barrel is provided with the cutting ring bulldozing device.Restrainting this bundle joint formula cutting ring soil sample barrel 5 is provided with and puts ring.
Get the enforcement principle of undisturbed soil, design and produce inside clearance ratio and be 0, blade angle 10%, area satisfy the bundle joint formula thin-walled of the taking I level original state sample shoe that fetches earth than 10%, on the structure, make internal diameter and test with the consistent pipe that fetches earth of cutting ring external diameter, cutting ring is built in the pipe that fetches earth, the pipe top of fetching earth is the disturbed soil of surplus soil pipe splendid attire soil sample barrel when being pressed into, the soil sample barrel catcher is pulled on the surplus soil pipe of piston closes upper discharge hole during trip-out, in soil sample barrel, form local decompression, adsorb the loose unlikely soil sample barrel of sand sample and in the last process of carrying, fall sample.Because in the direct indentation test cutting ring of sand sample, cutting ring take out the back just can be directly on machine test needn't the secondary sample preparation, solved the problem that loose sand sample can not the secondary sample preparation.
Specifically get the implementation method and the flow process of undisturbed soil
(1) be drilled into the need sampling depth, following clear hole drill tool is removed surplus soil in the boring;
(2) should restraint joint formula cutting ring soil sample barrel with drilling rod hangs to foot of hole;
(3) soil sample barrel is connected with the pressing mechanism rigidity of rig by drilling rod, is pressed into layer of sand sampling continuously by the rig soil sample barrel of exerting pressure, and it be beneficial that compression distance surpasses 9 long 15cm of sample, about 30～35cm, and it is undisturbed soil that assurance enters the liner soil sample that fetches earth;
(4) be depressed into the degree of depth and rise and unload drilling rod, draw the surplus soil pipe of piston closes upper discharge hole during trip-out on the soil sample barrel catcher, in soil sample barrel, form local decompression, adsorb the loose unlikely soil sample barrel of sand sample and in the last process of carrying, fall sample;
(5) soil sample barrel proposes fetch earth under the unloading behind the face of land shoe, Yu Tuguan, the cutting ring that sample will be housed with autocratic cutting ring bulldozing device release one by one the pipe that fetches earth can obtain testing laboratory directly installation non-quiet, move triaxial test I level original state sample.
Claims (5)
