[0036] See also Fig.10 The detection device 2 includes a pressing support plate 44, a pressing column 45, a displacement sensor 46 and an indicator rod 47. The upper end of the pressing column 45 is fixedly connected to the middle of the bottom end of the second sliding adjustment block 18, the displacement sensor 46 and the indicator rod 47 are fixedly connected to the outside of the upper end of the pressing column 45, and the pressing support plate 44 is fixedly connected to the bottom end of the pressing column 45.

[0037] The upper end surface of the baffle block 21 is smoothly inclined at 45°, so that the baffle block 21 can block the counterweight block 22 when it is exposed from the conveying track plate 20. When the counterweight block 22 slides back to its original position, it contacts and squeezes the inclined end surface, causing the baffle block 21 to shrink into the conveying track plate 20.

[0038] The front end of the pulling control rope 40 is fixedly connected to the bottom end of the sliding adjustment plate 29 at the corresponding position after passing through the blocking rod blocking guide inside the second fixed frame plate 34. The blocking block 21 is located between the gap of the counterweight block 22. A water inlet pipe is provided at the upper end of the main pressure caisson 7, and a drainage pipe is provided at the bottom end of one side of the main pressure caisson 7. There is a gap between the limit card frame 36 and the first sliding adjustment block 14, so that it will not get stuck during the rotation process.

[0039] The height of one end of the conveying track plate 20 on which the counterweight 22 is installed is higher than the height of one end of the conveying track plate 20 connected to the connecting plate 19. Since the first track ring 6 and the second track ring 8 are concentric rings, the first sliding adjustment block 14 and the second sliding adjustment block 18 can rotate synchronously along the first track ring 6 and the second track ring 8, and the counterweight 22 can slide smoothly along the conveying track plate 20.

[0040] Working principle: The device is lifted by the lifting and carrying ring 3 through the lifting device and placed inside the designated detection area. A large amount of liquid can be injected into the main pressure caisson 7 through the water inlet pipe arranged on the main pressure caisson 7, so that the second sliding adjustment block 18 is pressed by the main pressure caisson 7. When the detected location sinks, the second sliding adjustment block 18, the conveying track plate 20 and the limit card frame 36 are rotated inside the first sliding adjustment block 14. At this time, the pressing support plate 44 and the pressing column 45 are displaced downward. Since the contact area between the support base 1 and the detected point is large, the amount of settlement can be accurately calculated by observing the amount of change of the scale line on the observation scale frame 10 indicated by the indicator rod 47 within a certain period of time, and the settlement amount can be automatically detected by the displacement sensor 46 to transmit the signal to the receiving end for real-time monitoring, and the detection device 2 is provided with three areas that can perform synchronous three-point detection, so that the detection result is more accurate;

[0041] When the detection pressure needs to be increased during the detection process, the second motor 31 in each adjustment control part 5 is started to drive the first control gear 32 and the second control gear 33 to rotate. The first control gear 32 and the second control gear 33 rotate in opposite directions, and the rotating first control gear 32 and the second control gear 33 can drive the two adjustment gears 28 to rotate synchronously through the driving wheel 25 and the driving belt 26. The rotating adjustment gear 28 drives the sliding gear plate 35 to slide and rise inside the limit card frame 36. At this time, the extrusion control plate 38 moves upward, and the upwardly displaced extrusion control plate 38 will squeeze the sliding adjustment plate 29 in turn and compress and stretch the return spring 30 at the corresponding position so that the sliding adjustment plate 29 is on the second fixed frame plate The interior of the conveying track plate 20 sequentially slides upward, and since the bottom ends of the sliding adjustment plates 29 are respectively fixedly connected to the corresponding front ends of the pulling control ropes 40, the sliding adjustment plates 29 that slide upward sequentially will sequentially pull the pulling control ropes 40, so that the pulling control ropes 40 pull the blocking blocks 21 downward under the blocking of the blocking guide rods 41, and the reset springs 42 are extended, at which time the blocking blocks 21 used for the blocking counterweight blocks 22 will sequentially contract from front to back into the interior of the conveying track plate 20, and since the height of one end of the conveying track plate 20 on which the counterweight blocks 22 are installed is higher than the height of one end of the conveying track plate 20 connected to the connecting plate 19, the counterweight blocks 22 can slide on the conveying track plate 20 sequentially and orderly, and by controlling the conveying track plate 2 0. The height of the extrusion control plate 38 at one end can control the number of the isolation control device 39 extruding and colliding the sliding adjustment plate 29, so as to control the number of expansion and contraction of the isolation block 21 from front to back into the conveying track plate 20, and finally control the specified number of counterweight blocks 22 to slide along the conveying track plate 20 to the end of the conveying track plate 20 connected to the second sliding adjustment block 18, thereby increasing the pressure on the second sliding adjustment block 18 and the upper end of the pressing column 45 so that the second sliding adjustment block 18, the conveying track plate 20 and the limit card frame 36 rotate inside the first sliding adjustment block 14, and at this time, the pressing support plate 44 and the pressing column 45 move downward, thereby completing the settlement amount detection of different pressures, and the three adjustment control parts 5 can be independently The number of times the counterweight block 22 slides on the conveying track plate 20 is controlled, so that the settlement detection of different pressure values ​​in the three areas can be completed. By starting the first sliding adjustment device 4 and the first motor 17 in the second sliding adjustment device 9, the winding shaft 12 can be driven to reel in the control rope 13, and the first sliding adjustment block 14 and the second sliding adjustment block 18 are pulled by the control rope 13 to slide closer on the first track ring 6 and the second track ring 8. At this time, the three detection devices 2 are close to each other and can be concentrated on a single-point detection of an area. At this time, the pressure of the counterweight blocks 22 in the three adjustment control parts 5 can all act on this detection point, so that the device can apply different detection pressures according to different construction sites to detect the settlement.After the detection of the device is completed, the second track ring 8 is pulled by the external lifting device to make the second track ring 8 rise, so that the height of the end of the conveying track plate 20 close to the second track ring 8 is greater than the height of the end of the conveying track plate 20 close to the first sliding adjustment block 14, so that the counterweight blocks 22 on each conveying track plate 20 can be slid and reset, and after reset, they can be locked and fixed by the blocking block 21.
