[0020] Working principle of this embodiment: when it is necessary to predict the settlement coefficient of soft soil foundation, the support component 2 and the mobile structure 3 can be controlled to be installed and used in advance, so that the bottom end of the inner rod component 204 is first subjected to force and contacts the ground. After the inner rod component 204 is subjected to force, the spring outside the top rod component 206 is squeezed to generate a force to support the support component 2. Even if the inner rod component 204 is inserted into the soil, a certain resistance will be generated. Then the bottom of the outer plate 202 contacts the ground to produce a positioning installation effect, improve the stability of the support component 2, and prevent the support component 2 from sinking. Then the mobile structure 3 is controlled to move downward by the winch, so that the bottom end of the mobile structure 3 contacts the ground.

Since the pushing plate structure 304 is a structure with adjustable movement amplitude, It can ensure the prediction accuracy and the detection effect. When the mobile structure 3 cooperates with various sensors to settle, the mobile structure 3 drives the sensor slider 208 to move, so that the prediction sensor 207 transmits the data to the sub-control module 106, and other sensors also transmit the detected data to the sub-control module 106. The sub-control module 106 transmits the data to the data aggregation module 102 through the wireless network. The data aggregation module 102 gathers the various groups of data together and then transmits them to the calculation module 101. After precise calculation and analysis, the settlement coefficient is calculated. Then the data center 104 transmits the values ​​in the database to the comparison module 103. The calculation module 101 transmits the predicted values ​​to the comparison module 103. The comparison module 103 determines the accuracy and precision of the prediction data according to its own algorithm and comparison performance, and automatically corrects it, and then transmits it to the main controller 1 and the settlement diagram simulation module 105 to obtain an accurate settlement coefficient. Finally, the settlement of the soft soil foundation is observed through the display.
