It is mobile；
The sample transfer ring is made of muti-piece sample transfer piece, and the sample transfer piece is connect by elongation bar with the telescopic rod, described
Telescopic rod is the extensible member driven by hydraulic oil, and fluid pressure drive device is connected to by the first oil circuit and telescopic rod inside,
Sample transfer piece lower end, which is equipped with, bores sample notch；
The elongation bar is the extended part driven by hydraulic oil, and fluid pressure drive device passes through in the second oil circuit and the elongation bar
Portion's connection.
Fidelity method for making sample in situ includes positioning sampling, the forming of ring test mouth；
Positioning sampling is drilled sampling in pre- sample position with sample bar is bored, after boring the decentralization in place of sample bar, stops sampling and simultaneously fix
Sample bar is bored, is protected using sample bar is bored to boring sample；
The ring test mouth forming, extends driving sample transfer ring using telescopic rod and moves from top to bottom along sample bar is bored, utilize simultaneously
Elongation bar elongation driving sample transfer piece expands outwardly, and shapes ring test mouth.
A kind of Rock And Soil original position fidelity sample preparation device of the present invention and method have advantage:
(1) after sample required for taking by brill sample bar drill, locking button is tightened, so that sample bottom is not separated with Rock And Soil, is protected
The original position for holding sample is gradually bored using sample transfer ring except the Rock And Soil around sample；Elongation bar is controlled, so that boring on sample ring
Piece elongation is bored, gradually removes the Rock And Soil around sample, expands the space around sample, live shearing resistance can be carried out according to the later period
Strength test and space required for torsion shear apparatus is installed, and control the length of elongation bar.
(2) easy to operate, it is applicable in Rock And Soil, the soil body, structural plane etc. on site, by boring sample bar and boring the combination of sample ring,
Field influence with a varied topography is overcome, the operability of field test is realized, is established for the research of rock mechanical performance
Basis, and bore sample bar and bore between sample ring and have certain interval hole makes to bore sample ring and not make in the process of running to sample
At damage, guarantee the original position of sample.
