[0026] As shown in Figs. 1 to 4 The present embodiment provides a ground subsidence monitoring device, which is pre-buried on the ground to be observed. Here, the present embodiment lists a ground subsidence monitoring device using three dynamic settlement sensor assemblies, and other types such as four or more are not listed one by one. In addition, the pressure sensor 15 of the present embodiment is a mature product.
[0027] In the embodiment, the ground settlement monitoring device comprises a mounting support disc 6 fixedly attached to the ground, an outer pipe 1 arranged at the lower part of the mounting support disc 6, an inner pipe 2 arranged through the mounting support disc 6 and the outer pipe 1, a plurality of lower pre-buried support rods 3 arranged at the lower part of the inner pipe 2, an upper mounting cover 4 arranged on the mounting support disc 6, an observation point 18 arranged at the top center of the upper mounting cover 4, an upper support disc 7 arranged at the top of the inner pipe 2, a plurality of strip-shaped grooves 5 opened along the longitudinal direction at the peripheral edges of the upper mounting cover 4, a plurality of expansion screw assemblies 8 arranged on the mounting support disc 6, and a dynamic settlement sensor assembly arranged between the upper support disc 7 and the mounting support disc 6 and corresponding to the strip-shaped grooves 5. Here, the lower pre-buried support rods 3 and the outer pipe 1 are buried under the ground to be monitored. When the lower part of the ground where the mounting support disc 6 is located is settled, the lower pre-buried support rods 3 and the inner pipe 2 pull the upper support disc 7 downward, and the dynamic settlement sensor assembly is used to obtain the change in the settlement stress. In addition, when the area where the lower pre-buried support rods 3, the inner pipe 2, the mounting support disc 6 and the outer pipe 1 are located is not settled, but the peripheral part of the mounting support disc 6 is settled, the hollow ball 13 is used to transmit the change in the stress.
[0028] Specifically, the dynamic settlement sensor assembly comprises a support rod 9 arranged in a ring around the peripheral edge of the upper support disc 7 and arranged vertically to the strip-shaped grooves 5, a sleeve 11 sleeved on the support rod 9, a linkage swing lever 12 arranged at one end of the sleeve 11 and arranged through the strip-shaped grooves 5 at the middle part, a hollow ball 13 arranged at the other end of the linkage swing lever 12 and in contact with the ground, an upper connecting column 14 arranged at the bottom of the linkage swing lever 12 and placed in the upper mounting cover 4, a pressure sensor 15 fixedly arranged on the mounting support disc 6 and placed at the lower part of the upper connecting column 14, and a spring 19 hung between the upper connecting column 14 and the pressure sensor 15. When the ground where the mounting support disc 6 is located is not settled, but the peripheral part of the mounting support disc 6 is settled (or when the mounting support disc 6 is settled at the location where it is installed and the peripheral part of the mounting support disc 6 is not settled), the hollow ball 13 drives the linkage swing lever 12 to swing along the longitudinal direction of the strip-shaped grooves 5, and squeezes or pulls the spring 19, so that the measured data of the pressure sensor 15 changes, reminding the artificial collection of the position of the observation point 18. In addition, when the peripheral part of the mounting support disc 6 is not settled, but the lower part of the inner pipe 2 is settled, the inner pipe 2 pulls the upper support disc 7 to move along the longitudinal direction, which can also squeeze or pull the spring 19, so that the measured data of the pressure sensor 15 changes. When the data collected by the pressure sensor 15 changes by more than a preset threshold value, a reminder signal is given to the user. The user can then manually measure the position information of the observation point 18.
[0029] In the embodiment, in order to ensure reliable installation of the pressure sensor 15, a plurality of sensor installation grooves 10 are formed on the installation support disc 6, and a first through hole is formed in each sensor installation groove 10. In addition, a threaded hole 16 corresponding to the first through hole is arranged at the bottom of the pressure sensor 15, and the threaded hole 16 is connected with the installation support disc 6 by a screw rod. In addition, a spring hanging hole 17 is formed on the upper connecting column 14 and the pressure sensor 15, respectively, and the two ends of the spring 19 are hung in the spring hanging hole 17, so as to reliably install the spring 19 and transmit the force of the spring 19.
