The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
1-catcher 2-shadoof
The surplus soil pipe of 3-piston 4-
5-tube connector 6-connects hoop
7-fetches earth and manages the 8-liner
Quiet, moving three soil samplers of lined thin-walled mainly comprise catcher 1, shadoof 2, piston 3, surplus native pipe 4, tube connector 5, connection hoop 6, the pipe 7 that fetches earth, boots association, liner 8 compositions.Quiet moving three soil samplers of a kind of lined thin-walled comprise catcher 1 and piston 3, and catcher 1 connects piston 3, are provided with shadoof 2 between quiet moving three soil samplers catcher 1 of this lined thin-walled and the piston 3; Quiet moving three soil samplers of described lined thin-walled comprise the surplus soil pipe 4 and the pipe 7 that fetches earth, wherein fetching earth and managing 7 tops is surplus soil pipe 4, surplus soil pipe 4 and fetch earth and be provided with tube connector 5 between the pipe 7 is provided with to be connected between fetch earth pipe 7 and the tube connector 5 of quiet moving three soil samplers of this lined thin-walled and binds round 6; Liner 8 internal diameters of quiet moving three soil samplers of described lined thin-walled are consistent with quiet, moving triaxial test sample external diameter, are built in the pipe 7 that fetches earth in the quiet liner 8 that moves three soil samplers of described lined thin-walled.The surplus soil pipe 4 of quiet moving three soil samplers of this lined thin-walled is provided with steam vent, and the quiet moving three soil samplers catcher 1 of this lined thin-walled is pulled on the surplus soil pipe of piston 3 sealings 4 upper discharge hole during trip-out.Quiet moving three soil samplers of this lined thin-walled are provided with boots association.Quiet moving three soil samplers of this lined thin-walled are provided with the liner that retainer ring is inserted in the pipe exposure of fetching earth.Quiet moving three soil samplers of this lined thin-walled are provided with the liner that retainer ring is inserted in exposure in the boots association.Quiet moving three soil samplers of lined thin-walled are simple in structure, easy to use, are easy to safeguard, are easy to success and take quiet, the moving needed I level of triaxial test original state sample.Quiet, moving three soil samplers of lined thin-walled are applicable to that boring takes to carry out the required I level original state sample of quiet, moving triaxial test test in the glued pure mine tailing layer of sand of loosely organized nothing.For the prospecting on mining tailing wasteland and similar stratum later on provides reliable sampling technique means.
The lined thin-walled is quiet, moving three soil sampler courses of work are: design and produce inside clearance ratio and be 1%, blade angle 10%, area than 13%, on the structure the satisfied thin-walled of taking I level original state sample fetch earth pipe, boots association, make the internal diameter liner consistent and place the pipe that fetches earth with quiet, moving three sample external diameters, the pipe top of fetching earth is the disturbed soil of surplus soil pipe splendid attire soil sampler when being pressed into, the soil sampler catcher is pulled on the surplus soil pipe of piston closes upper discharge hole during trip-out, in soil sampler, form local decompression, adsorb the loose unlikely soil sampler of sand sample and in the last process of carrying, fall sample.Because the liner internal diameter is consistent with quiet, moving triaxial test sample external diameter, in liner sample 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.
The process that fetches earth specific embodiment
(1) be drilled into the need depth selection, following clear hole drill tool is removed surplus soil in the boring;
(2) with drilling rod " quiet, moving three soil samplers of lined thin-walled " are hung to foot of hole;
(3) soil sampler is connected with the pressing mechanism rigidity of rig by drilling rod, is pressed into layer of sand sampling continuously by the rig soil sampler of exerting pressure, and it be beneficial that compression distance surpasses 2 long 15cm of sample, 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 sampler catcher, in soil sampler, form local decompression, adsorb the loose unlikely soil sampler of sand sample and in the last process of carrying, fall sample;
(5) soil sampler proposes fetch earth under the unloading behind the face of land pipe, boots association, the retainer ring (3～4) of autocracy is inserted in the liner of exposure in the pipe that fetches earth, the boots association, liner is taken out sealing (the slip retainer ring is to keep the liner shape while pulling out) can obtains directly quiet, the moving triaxial test I level original state sample of installation of test room with the autocratic lining device that pulls out.
