[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-4 A scalable urban land subsidence monitor includes a device base 1, a device top plate 12 is arranged above the device base 1, a measurement control box 2 is arranged on the top of the device top plate 12, the top of the measurement control box 2 is rounded, a wireless transmitter is installed on the measurement control box 2, such as an NB-IOT module, for transmitting signals, the measurement control box 2 is fixedly connected to the device top plate 12, a plurality of pressure sensors 3 are arranged on the top of the device base 1, and the pressure sensors 3 are arranged in a matrix, the pressure sensors 3 are fixedly connected to the device base 1, the pressure sensors 3 are electrically connected to the measurement control box, and two groups of four limit blocks 7 are arranged on the top of the device base 1, The two telescopic rods 9 correspond to the following ones, and each limit block 7 is fixedly connected to the equipment base 1. Two limit columns 5 are provided on the top of the equipment base 1, and the two limit columns 5 are the same size. Two telescopic rods 9 are provided on the top of the equipment base 1, and the two telescopic rods 9 are fixedly connected to the equipment base 1. Two connecting rods 4 are provided on the top of the telescopic rod 9, and each connecting rod 4 is the same size. The connecting rod 4 completely passes through one side of the telescopic rod 9. A device top plate 12 is provided on the top of the equipment base 1, and a rotating wheel 6 is provided on the top of the equipment top plate 12. A limit strip 8 is provided on the top of the equipment base 1, and a threaded column 10 is provided at the bottom of the rotating wheel 6, and a settlement plate 11 is provided at the bottom of the threaded column 10.

[0028] When the user is in use, by installing the measurement control box 2 and the pressure sensor 3 on the top of the equipment top plate 12 and the equipment base 1, it is realized that when using the expandable urban ground subsidence monitor, the data can be measured by installing the pressure sensor 3 and the signal can be transmitted by the wireless transmitter. In this way, a large number of monitoring equipment will not be used to work when in use, which greatly increases the efficiency of the use of the subsidence monitor. In this way, a rotating wheel 6 is provided on the top of the equipment top plate 12, so that when using the expandable urban ground subsidence monitor, the threaded column 10 can be moved downward by the rotating wheel 6 to drive the subsidence plate 11, so that it can be more convenient when in use, and the installation is simpler and more convenient. At the same time, a subsidence plate 11 is provided at the bottom of the rotating wheel 6, so that when using the expandable urban ground subsidence monitor, more accurate data can be provided, so that the durability of the subsidence plate 11 is stronger, and the construction efficiency is improved at the same time. The subsidence plate 11 produced by the manufacturer of the subsidence plate 11 can improve the construction efficiency. Since the installation of the subsidence plate 11 is simple and convenient, the construction time can be reduced.

[0029] At the same time, the user monitors the ground subsidence by measuring the elevation change of the ground through the measurement control box 2 and the pressure sensor 3. The expandable urban ground subsidence monitoring system is usually composed of multiple measurement units, each of which can independently measure the ground subsidence of an area, and then summarize and analyze the data of multiple measurement units to obtain the ground subsidence of the entire city. At the same time, the pressure sensor 3 and the measurement control box 2 measure the pressure and displacement of the ground and other parameters to calculate the ground subsidence. Therefore, when installing the sensor, it is necessary to pay attention to the sensitivity and accuracy of the sensor to ensure the accuracy of the measurement results. The equipment base 1 is buried in the ground, and the settlement plate 11 is fitted and connected to the ground to perform a positioning connection with the ground. The limit strip 8 runs through the telescopic rod 9, and the limit strip 8 is fixed by two limit columns 5. In this way, it can be well fixed when the ground settles, and the telescopic rod 9 will not be forced to move due to ground settlement. Specific embodiment 2:

[0031] Reference Figure 1-4 , a vibration detector is installed on the equipment base 1, and the vibration detector is electrically connected to the measurement control box 2. The vibration sensor is used to detect the deformation of the building structure. The vibration sensor can convert the vibration changes of the building into electrical signals and accurately measure the settlement. The advantage of vibration monitoring technology is that the data is accurate and reliable, and more detailed deformation information can be obtained.

[0034] 2. By adding a limit block 7 on one side of the telescopic rod 9, the telescopic rod 9 can be stably fixed by two limit blocks 7 when the expandable urban land subsidence monitor is used. At the same time, the limit column 5 completely penetrates the limit block 7 and the telescopic rod 9, so that it can be assembled and disassembled faster when in use, which greatly increases the convenience;

[0035] 3. A rotating wheel 6 is provided on the top of the top plate 12 of the device, so that when the expandable urban land subsidence monitor is used, the threaded column 10 can be moved downward by the rotating wheel 6 to drive the subsidence plate 11, which is more convenient when used and easier to install;

[0036] 4. A settlement plate 11 is provided at the bottom of the rotating wheel 6, so that more accurate data can be provided when using the expandable urban ground settlement monitor, so that the durability of the settlement plate 11 is stronger, and the construction efficiency is improved. The settlement plate 11 produced by the settlement plate 11 manufacturer can improve the construction efficiency. Since the settlement plate 11 is simple and convenient to install, the construction time can be reduced.
