(1) with the soil layer surface of protective screen auxiliary device setting near protective screen setting area, operating personnel adjusts sleeve slide rail to accurate position about through sleeve slide rail system 3.

(2) The switching knob 536 is adjusted to be in a descending state, the power supply is connected, the control switch 23 is turned on, the motor rotor drives the transmission gear 441 to rotate at the moment, then the transmission gear 441 drives the vertical gear 47 to rotate, the vertical gear 47 drives the connecting rod 46 to rotate in a vertical plane, so that the connecting rod 46 can move up and down, due to the existence of the vertical rotating device 43, only the upper end of the vertical swinging rod 45 is allowed to rotate relative to the connecting rod 46, the rest directions of the vertical swinging rod 45, up, down, left, right, front and back, form constraint, the rotation of the vertical gear 47 can cause the lower end of the vertical swinging rod 45 to transversely swing in the vertical plane through the connecting rod 46, the lower end of the vertical swinging rod 45 only needs to. The bolt passes through the bolt hole 492 to fix the slanting rod 49 on the side of the sleeve sliding rail, so as to realize the vertical rotation of the slanting rod 49 around the bolt hole 492 to form a lever, the vertical swing rod 45 transmits the vertical displacement to the transverse rod 41, so that the two ends of the transverse rod 41 move up and down, the sliding chuck 491 of the slanting rod 49 rotates in an arc under the lever action of the slanting rod 49, the generated transverse displacement will cause adverse effect on the lifting device 5, so the transverse cavity is arranged in the bearing platform 51 to counteract the transverse displacement of the sliding chuck 491, at the same time, the vertical displacement is smoothly transmitted to the articulator 53 through the connecting rod 54, the articulator sliding rail 56 enables the articulator 53 to only perform the vertical displacement, the switching knob 536 rotates clockwise, then the descending crankshaft 5372 will push out the lower occlusal plate 5321 through the first bearing rod 5325 and the first telescopic rod 5322, at this time, the lower occlusal plate 5321 is embedded in the descending slot 132, so as to drive, the soil cutting knife 12 has a shearing effect on soil, so that the descending of the sleeve 1 can be accelerated, the articulator 53 repeatedly moves up and down, the lower occlusal plate 532 is retracted into the vertical surface of the articulator 53 due to the inclined cutting surface of the lower occlusal plate 5321 and the existence of the left spring piece 538 and the right spring piece 535 in the ascending process, and when the articulator 53 returns to the highest position again, the lower occlusal plate 5321 automatically pops up, the action is repeated, and the descending power is repeatedly provided for the sleeve.

(3) After the sleeve 1 descends to a designated position, the switching knob 536 is rotated to switch to an upper gear, at the moment, the upper bite plate 5331 automatically pops, the lower bite plate 5332 is retracted into the articulator 53 under the action of the second spring 5324, the ascending process is not affected, the articulator 53 moves up and down in the ascending process, the principle is the same as that of the descending process, a soil sample is taken out of the surface due to frictional resistance generated by the contact of the soil body and the inner arm of the sleeve 1, and a cavity is formed in the soil body.

(4) And placing vibration isolation materials, placing the vibration isolation materials in the hollow cavity, and carrying out vibration isolation test research.

(5) After the test is completed, the vibration isolation material is taken out and the taken earth is filled back to the original position.
