[0017] The following components are marked as follows: road base 1, soft base 2, bearing layer 3, support column 4, settlement sleeve 5, settlement plate 6, wireless transmission ranging component 7, breadboard 71, development board 72, ultrasonic rangefinder 73, power supply 74. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the soft base settlement monitoring device of this utility model includes a support column 4, a settlement sleeve 5, a settlement plate 6, and a wireless transmission ranging component 7. The support column 4 is vertically installed in the soft base 2, and the bottom of the support column 4 is installed on the bearing layer 3. The settlement sleeve 5 is provided with an installation through hole, which is arranged along the vertical central axis of the settlement sleeve 5. The settlement sleeve 5 is vertically fitted onto the support column 4 through the installation through hole. The settlement sleeve 5 can move up and down along the support column 4. The settlement plate 6 is horizontally installed on the top of the settlement sleeve 5 and the top of the soft base 2. The middle part of the settlement plate 6 is located at the upper opening of the installation through hole.

[0020] The wireless transmission ranging component 7 is mounted on the support column 4 and is located in the mounting through hole.

[0021] The geological strata, from top to bottom, consist of a roadbed 1, a soft base 2, and a bearing layer 3. The bottom of the support column 4 is placed on the bearing layer 3, ensuring the installation strength of the entire settlement monitoring device. The settlement plate 6 is horizontally installed on top of the soft base 2, which is also the bottom of the roadbed 1. When the soft base 2 settles, the settlement plate 6 and the settlement sleeve 5 also descend downwards along the support column 4 by a corresponding distance. The distance that the settlement plate 6 descends is the distance that the soft base 2 settles.

[0022] The wireless transmission ranging component 7 has two main functions. One function is to measure the distance between it and the settlement plate 6. When the distance between the wireless transmission ranging component 7 and the settlement plate 6 decreases, it means that the soft base layer 2 has settled. The settlement distance of the soft base layer 2 is the difference in distance between the wireless transmission ranging component 7 and the settlement plate 6. The other function is to transmit the measured data to an external computer receiver so that the monitoring personnel can know it.

[0023] Specifically, to ensure the effectiveness of the wireless transmission ranging component 7, a preferred structure for the wireless transmission ranging component 7 is as follows: For example... Figure 1 , Figure 2 As shown, the wireless transmission ranging component 7 includes a breadboard 71, a development board 72, an ultrasonic rangefinder 73, and a power supply 74. The breadboard 71 is horizontally mounted on top of the support column 4. The development board 72, ultrasonic rangefinder 73, and power supply 74 are all mounted on the breadboard 71. The development board 72 is electrically connected to the ultrasonic rangefinder 73, and the power supply 74 is connected to the development board 72 and the ultrasonic rangefinder 73 respectively via power cables. The ultrasonic rangefinder 73 is used to measure the distance between itself and the settlement plate 6 and transmits the measured data to the development board 72, which then transmits the measured data to an external computer receiver. To ensure the accuracy of the ultrasonic rangefinder 73's measurement, the ultrasonic rangefinder 73 is located on the vertical central axis of the mounting through hole. The development board 72 is preferably an ESP32 development board, which has a simple structure, high stability, and can be programmed.

[0024] To facilitate the installation and use of the wireless transmission ranging component 7, for example... Figure 1 As shown, the wireless transmission ranging component 7 is installed on the top of the support column 4.

[0025] To ensure the service life of the support column 4, settlement sleeve 5, and settlement plate 6, all support columns 4, settlement sleeve 5, and settlement plate 6 are made of steel.

[0026] To further improve the measurement accuracy of the ultrasonic rangefinder 73, the settling plate 6 is circular or rectangular in shape, and the center of the settling plate 6 is located at the upper opening of the mounting through hole.

[0027] In order to effectively reduce the possibility of the settlement sleeve 5 shifting, the installation through hole of the settlement sleeve 5 is connected to the support column 4 by clearance fit. The clearance fit can ensure that the settlement sleeve can move up and down along the support column.

[0028] To reduce the possibility of groundwater intrusion into the settlement casing 5 and causing damage to the wireless transmission ranging component 7, for example... Figure 1 As shown, a waterproof tape 8 is provided between the settlement sleeve 5 and the support column 4. The waterproof tape 8 is located below the wireless transmission ranging component 7. Preferably, the waterproof tape 8 is wrapped around the outer circumferential surface of the support column 4.
