The rotating steering wheel 130 is turned, and the rotating steering wheel 130 drives the rotating internal threaded tube 120 to rotate. The rotating internal threaded tube 120 drives the threaded column 290 through the principle of thread transmission, and the threaded column 290 is gradually inserted into the threaded rod sliding end 250. Since the second limit pin 264 can slide in the installation groove 263, the threaded rod sliding end 250 can fall on the top of the connecting seat 270 under the action of gravity, reducing the external force shared by the pressing connecting rod seat 260, so that the pressure of the threaded column 290 can be fully transmitted to the pressure sensor 280, reducing the situation where the pressure actually measured by the pressure sensor 280 is too small due to the pressure on the pressing connecting rod seat 260.

[0033] Specifically, the working principle of the flat plate sinkage meter is as follows: when the three sets of leg structures 300 are unfolded, the double-ear seat 312 at the upper end of the support rod 311 is connected to the second single-ear seat 140 on the outer wall of the bearing cylinder 111 through a pin shaft, and the double-ear seat 312 at the lower end of the support rod 311 is pinned to the bottom plate 331 through the first single-ear seat 332 through a pin shaft, and the two ends of the first rod body 411 are connected to the first connecting plate 320 on the adjacent support rod 311 through the first mounting seat 412, and the first mounting seat 412 and the first connecting plate 320 are fixed by bolt connection, and the three support rods 311 are spread apart by the first rod body 411, and the pressure transmission structure 200 is kept stable through the support of the second rod body 421, so that the flat plate sinkage meter is fixed in a triangular shape to ensure its structural stability. The second connecting plate 213 on the fixed cylinder seat 210 is connected to the second mounting seat 422 on the second rod body 421 through bolts, and the cylinder seat 210 is fixed through the support of the second rod body 421 to keep the fixed cylinder seat 210 stable. In this way, the state of the pressure transmission structure 200 is maintained. By removing the connecting bolts of the first pull rod 410 and the second pull rod 420, the legs 310 can be folded up for storage, reducing the storage space, and the legs 310 can be removed by pulling out the pins at the upper ends of the legs 310. The flat plate subsidence instrument is assembled by assembling, and each component is light in weight, and a single person can complete the handling work, which is convenient for assembling the flat plate subsidence instrument with less manpower.

[0034] After the three sets of leg structures 300 are unfolded, the flat plate sink meter is placed on the ground to be tested, and the leg structures 300 are fixed by steel chisels, anchor bolts or loading weights. Under the action of gravity, the pressure plate contacts the ground, and the threaded rod sliding end 250, the connecting seat 270, the pressure sensor 280, the pressure rod sliding end 240 and the pressure rod 230 are pressed in sequence. Thereafter, the pressure sensor 280 and the display are powered on and zeroed, and the second limit pin 264 can slide up and down in the installation groove 263 with a movement margin. The upper end of the connecting plate 261 is stabilized on the threaded rod sliding end 250 by the first limit pin 262 and the fastener 265, and the pressure rod sliding end 240 and the threaded rod sliding end 250 are connected to each other by the connecting rod seat 260, so as to reduce the occurrence of the pressure rod sliding end 240 and the threaded rod sliding end 250 being separated from each other. The rotating steering wheel 130 is turned, and the rotating steering wheel 130 drives the rotating internal threaded tube 120 to rotate. The rotating internal threaded tube 120 drives the threaded column 290 through the principle of threaded transmission. The threaded column 290 is gradually inserted into the sliding end 250 of the threaded rod. Since the second limit pin 264 can slide in the installation groove 263, the external force shared by the compression connecting rod seat 260 is reduced, so that the pressure of the threaded column 290 can be fully transmitted to the pressure sensor 280, and the pressure sensor 280 actually measures a small pressure due to the pressure on the compression connecting rod seat 260. The rotating steering wheel 130 is continued to be turned, and the rotating steering wheel 130 drives the threaded column 290. The threaded column 290 drives the pressure rod 230 to move downward, and the pressure rod 230 drives the pressure plate to move downward and sink into the soil. The depth of the pressure plate sunk into the soil is measured by the scale structure 500. At the same time, the threaded column 290 applies pressure to the threaded rod sliding end 250, and the rotation of the threaded rod sliding end 250 is limited by the pressure connecting rod seat 260, thereby reducing the rotation of the pressure rod sliding end 240, thereby reducing the rotation of the pressure rod 230 and the pressure plate, and the threaded rod sliding end 250 transmits pressure to the connecting seat 270 and the pressure sensor 280, and the pressure on the pressure sensor 280 is then transmitted to the pressure rod sliding end 240 and the pressure rod 230, and finally the pressure is transmitted to the pressure plate. The applied pressure is measured by the pressure sensor 280. The depth of the corresponding pressure plate sunk into the soil and the pressure data measured by the pressure sensor 280 are recorded, and the accurate land bearing capacity can be obtained by analyzing and calculating the measured data.

[0035] It should be noted that the specific model specifications of the pressure sensor 280 and the display need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.

[0036] The power supply and principle of the pressure sensor 280 and the display are clear to those skilled in the art and will not be described in detail here.
