The upper surface of the connecting disk 509 is fixedly connected with a positioning disk 513. The cross-section of the positioning disk 513 is "T"-shaped. The lower surface of the positioning disk 513 fits with the upper end of the piston rod 511. After the piston rod 511 is inserted into the inner wall of the connecting hole 510, the piston rod 511 can be made to abut against the lower surface of the positioning disk 513, thereby achieving the effect of enabling several piston rods 511 to be quickly moved to a neat position.

[0051] The effect achieved by the entire marking device 5 is that, by setting the marking device 5, the test position can be conveniently marked after the foundation bearing test, thereby facilitating personnel's subsequent evaluation and analysis of the foundation bearing capacity, thereby improving the practicability of the device.

[0052] The overall working principle is that before conducting a load-bearing test of a building foundation, the test tube 1 is first moved to a designated test position with the aid of a grip ring 6, and then the positioning pin 9 on the lower surface of the positioning ring 45 is inserted into the foundation to support and fix the test tube 1. When conducting the experiment, personnel can put their feet on the pedal 8, so that the test tube 1 can be supported and stabilized during the experiment. When it is necessary to use the adjustment device 3 to impact the foundation to conduct a foundation load-bearing test, the impact component 34 can be controlled with the aid of the adjustment component 33. The specific steps are: first operate the control panel 2 to start the servo motor 331 to rotate, and the servo motor 331 drives the turntable 332 to rotate. During the rotation, the boss 333 is driven to slide along the inner wall of the slide rail 336, and at the same time When the cam 333 is in motion, the slide rail 336 drives the sliding plate 335 to slide along the inner wall of the sliding hole 334. The continuous rotation of the turntable 332 can drive the sliding plate 335 to continuously reciprocate on the inner wall of the sliding hole 334. The sliding plate 335 drives the impact column 341, and the impact column 341 drives the counterweight block 342, so that the counterweight block 342 can continuously impact the foundation with the help of the rubber cam 37, so that the load-bearing capacity of the foundation can be experimentally tested. By setting the adjusting device 3, the counterweight block 342 can be automatically driven to continuously impact the foundation, and then the foundation load-bearing test operation can be carried out according to the situation of the foundation after the impact. The device has high automation, saves manpower, and is worthy of in-depth promotion.

[0053] Among them, when the sliding plate 335 drives the impact column 341 to move up and down, the positioning plate 35 fixed on the impact column 341 will move along the inner wall of the positioning groove 36 on the experimental tube 1, thereby achieving the effect of limiting the impact column 341, thereby making the reciprocating motion of the impact column 341 smoother. In addition, during the rotation of the turntable 332, the round rod 339 fixed at the centrifugal position of the turntable 332 will slide along the inner wall of the annular rail 338, thereby limiting the rotation process of the turntable 332 and making the rotation of the turntable 332 more stable.

[0054] When it is necessary to sample the foundation soil at the experimental location, first operate the control panel 2 to start the drive motor 442, the drive motor 442 drives the active gear 443 to rotate, the active gear 443 drives the driven gear 444 to rotate, the driven gear 444 drives the screw rod 445 meshing therewith to rotate, the screw rod 445 drives the sampling head 47 to enter the foundation soil, during the movement of the screw rod 445, the positioning ring 45 can limit it, so as to avoid rotational deviation during the movement of the screw rod 445, and at the same time the screw rod 445 will drive the sampling auger 46 to move synchronously with the sampling head 47, when the sampling auger 46 completely enters the foundation Then, the servo motor 331 is started to drive the driving gear 443 to rotate in the opposite direction, so that the sampling auger 46 takes the foundation sample out of the foundation, and then the sample can be taken out from the sampling hole 43 to complete the sampling operation, wherein, by setting one end of the sampling head 47 as a conical structure, the process of the sampling head 47 entering the foundation is achieved to be smoother, and by setting the sampling device 4, after the foundation bearing capacity test is carried out, the foundation soil at the test position can be automatically sampled, and then the sample can be tested to determine whether the foundation material is qualified and compliant, thereby improving the functionality of the building foundation bearing capacity test device.

[0055] When the experimental position needs to be marked after the foundation load-bearing experiment, first rotate the adjusting ring 506 to drive the rubber pad 507 to move along the arc surface of the limiting rod 505, so that the adjusting ring 506 drives the rubber pad 507 to separate from the fixing seat 501, and then rotate the connecting plate 503 to drive the connecting disk 509 to make the connecting disk 509 in a horizontal state, and then rotate the adjusting ring 506 to drive the rubber pad 507 and the fixing seat 501 foundation, and finally move the piston rod 511 with the help of the anti-slip groove, pull the piston rod 511 out of the connecting hole 510, and then move the suction cup 512 to adsorb on the foundation position after the test, so that the experimental position can be marked. After the piston rod 511 in the connecting hole 510 is used, a new piston rod can be replaced. By inserting the rod 511 into the connecting hole 510, the marking structure can be supplemented. After the rotating adjusting ring 506 is separated from the fixing seat 501, the coil spring 508 can drive the connecting disk 509 to quickly rotate in the direction close to the experimental tube 1, thereby achieving the effect of quickly storing the connecting disk 509. Among them, after the piston rod 511 is inserted into the inner wall of the connecting hole 510, the piston rod 511 can be abutted against the lower surface of the positioning disk 513, thereby achieving the effect of enabling several piston rods 511 to be quickly moved to an orderly position. By setting the marking device 5, after the foundation bearing test is carried out, the experimental position can be conveniently marked, which is convenient for personnel to evaluate and analyze the foundation bearing capacity at a later time, thereby improving the practicability of the device.
