[0028] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By providing the connecting belt 1, when the user needs to perform settlement monitoring on the pipeline, at this time, the connecting belt 1 is wound around the outside of the pipeline in the foundation pit. One end of the connecting belt 1 is passed through the inside of the fixed frame 24, the second limiting plate 25 is inserted into the inside of the fixed frame 24, and the threaded column 26 is rotated to squeeze the second limiting plate 25, thereby fixing the connecting belt 1 to the outside of the pipeline. Then, by providing the first connecting pipe 3, the first connecting pipe 3 is picked up to drive the second connecting pipe 27 at the bottom to move. The second connecting pipe 27 is aligned and inserted into the inside of the first fixing groove 7. At the same time, the first limiting plate 19 is aligned and inserted into the inside of the second limiting groove 18. Then, when the second connecting pipe 27 is inserted into the bottom of the first fixing groove 7, the clamping ring 14 presses down on the outer inclined surface of the moving plate 10, so that the moving plate 10 moves inside the second limiting hole 15 and squeezes and compresses the spring 22. At the same time, under the push of the spring 22, the moving clamping ring 14 is engaged with the clamping groove 13, thereby performing upper and lower limiting on the clamping ring 14 and the second connecting pipe 27. Thus, the connection between the first connecting pipe 3 and the fixing plate 2 is completed. By the same method, another first connecting pipe 3 is continuously connected to the top surface of the first connecting pipe 3 until the first connecting pipe 3 extends out of the ground from the foundation pit. By the same method, the moving pipe 4 is connected to the topmost first connecting pipe 3. When disassembly is required, the second rotating plate 23 is toggled to drive the first limiting hole 12 to rotate and push the moving column 11 and the moving plate 10 to move so that the clamping groove 13 is no longer engaged with the clamping ring 14, and the second connecting pipe 27 can be pulled out of the inside of the first fixing groove 7 to release the connection. After the pipeline to be monitored is buried, the measuring mechanism 5 is sleeved on the outside of the moving pipe 4 and fixed to the ground. Thus, the settlement condition of the pipeline is observed by the cooperation of the scale on one side of the measuring mechanism 5 and the moving pipe 4. The specific measurement method has been pointed out in the reference document, and the monitoring principle herein is the same as that, so it will not be elaborated. Thus, the effect of connecting the fixing plate 2, the first connecting pipe 3 and the moving pipe 4 is comprehensively achieved, so that the first connecting pipe 3 can be lengthened when the length is insufficient. When lengthening, only the second connecting pipe 27 needs to be inserted into the inside of the first fixing groove 7, and the second rotating plate 23 can be toggled for disassembly. The operation is relatively convenient, avoiding the inability to measure deeper pipelines, meeting the requirements of different measurement scenarios, and being relatively practical.
