[0002] With the continuous development of urban infrastructure, most municipal pipelines are currently buried underground to reduce the interference caused by the external environment. However, the problem of underground pipeline settlement is becoming increasingly prominent. Pipeline settlement not only affects the integrity of the road surface, but also poses a potential threat to other underground facilities. Pipeline settlement may also cause cracks in the road surface and eventually collapse. This collapse not only threatens people's lives and safety, but may also cause a certain degree of damage to road traffic and other power, communication and other pipelines, thereby increasing unnecessary repair and maintenance costs. In order to avoid deformation of the pipeline caused by excessive settlement, it is necessary to use a detection device to detect the settlement of the pipeline.

[0003] At present, the main methods for measuring pipeline settlement are: leveling method, that is, by setting level points above or near the pipeline, using a level to measure the elevation difference between each point, so as to determine whether the pipeline has settled. The leveling method requires precise instruments and professional operators. During the measurement process, multiple stations, observations and records are required. The operation is highly complex and requires high skills and experience of the operators. Its accuracy is greatly affected by weather conditions. For example, severe weather conditions such as strong winds, heavy fog, and rain can make observations difficult, thereby reducing measurement accuracy. The cost of these devices is usually high. At the same time, in order to maintain the accuracy and stability of the equipment, regular maintenance and calibration are required, which will also increase additional costs. Utility Model Content

[0024] The pipeline settlement detection device of the present utility model is described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0026] The pipeline settlement detection device of this embodiment, see Figure 1-Figure 5 The device detects the position of the pipeline at that location through multiple groups of detection components set at both ends of the underground pipeline support components, and transmits data through displacement sensors and combines with computers for detection. No manual work is required during the measurement process, no station setting, observation and recording are required, and it is not affected by weather conditions. The device has high detection efficiency, simple structure, low cost, and low maintenance and calibration costs. It mainly includes multiple pipeline support components 2, the pipeline support component 2 includes a pipeline base 21, a hoop 22 is fixedly provided on the top of the pipeline base 21, the hoop 22 includes two symmetrically abutted pipe clamps 221, a pipeline 1 is arranged in the hoop 22, and bolts 222 are provided on the hoop 22 to fasten the two pipe clamps 221. The pipeline base 21 and the hoop 22 fix and limit the pipeline 1, and mounting holes 223 are vertically opened on the wing plates at both ends of the hoop 22.

[0027] In order to conveniently detect the settlement of the pipeline, in this embodiment, refer to Figure 2-Figure 5 , the installation through hole 223 is provided with a detection component 3, the detection component 3 includes a shell 31, the shell 31 is detachably fixedly arranged in the installation through hole 223, the shell 31 passes through the hoop 22, the upper end of the shell 31 is located above the upper surface of the hoop 22, and the lower end of the shell 31 is located below the lower surface of the hoop 22. A settlement detection tube 35 is fixedly arranged at the upper end of the shell 31, and the settlement detection tube 35 is connected with the shell 31. The shell 31 is in a cylindrical structure. The internal cavities of the shell 31 and the settlement detection tube 35 are both cylindrical structures. The inner diameter of the settlement detection tube 35 is smaller than the inner diameter of the shell 31, which is convenient for the displacement sensor 39 to transmit data more accurately.

[0028] The shell 31 contains liquid water, and the top surface of the liquid water is always in the sedimentation detection tube 35. A piston plate 32 is provided inside the shell 31 at the bottom of the liquid water. The upper and lower ends of the side walls of the piston plate 32 are provided with sealing rings to increase the sealing of the liquid water in the chamber. A sedimentation detection rod 34 is fixedly connected to the center of the bottom of the piston plate 32. The bottom of the sedimentation detection rod 34 penetrates the bottom wall of the shell 31 and is slidably arranged outside the shell 31, and a sealing belt is provided at the penetration point. A spring 33 is fixedly sleeved around the subsidence detection rod 34 between the bottom of the piston plate 32 and the bottom wall of the inner cavity of the shell 31, and the top of the spring 33 is fixedly connected to the bottom of the piston plate 32, and the bottom of the spring 33 is fixedly connected to the inner wall of the shell 31. A detection moving block 36 is slidably arranged in the subsidence detection tube 35, and the detection moving block 36 floats on liquid water. A displacement sensor 39 is arranged on the top wall inside the subsidence detection tube 35 to transmit the recorded position of the detection moving block 36, and different positions represent different amounts of subsidence. A limit block 37 is fixedly arranged on the upper inner wall of the subsidence detection tube 35, and a buffer pad is arranged at the bottom of the limit block 37 to prevent the detection moving block 36 from hitting the displacement sensor 39 and prevent the displacement sensor 39 from being damaged.

[0029] In order to make the sedimentation data more accurate, in this embodiment, see Figure 3 and Figure 4 The inner diameter of the sedimentation detection tube 35 is smaller than the inner diameter of the shell 31. When the piston plate 32 moves upward a short distance inside the shell 31, the detection moving block 36 can move upward a longer distance, which amplifies the sedimentation data, thereby facilitating the displacement sensor 39 to transmit data more accurately.

[0030] It can be understood that the cross-sectional area of ​​the inner cavity of the sedimentation detection tube 35 is a, and the cross-sectional area of ​​the inner cavity of the shell 31 is 8a. When the piston plate 32 rises 1mm, the detection moving block 36 rises 8mm, thereby transmitting data more accurately. Multiple pipeline support components 2 can be set on the pipeline 1. The two data detected by the detection components 3 set at both ends of each pipeline support component 2 are a group, and multiple groups of data can be generated. By modeling the position of the pipeline 1 through multiple groups of data, the degree of sedimentation can be seen more accurately, and then a more appropriate solution to the sedimentation problem can be found, which improves efficiency and avoids causing greater losses.

[0031] A limit protection shell 4 is provided outside the detection component 3 to protect the structure of the detection component 3 from being corroded and damaged by other underground substances. The bottom surface height of the limit protection shell 4 is higher than the bottom surface height of the pipeline base 21. In this way, when the pipeline base 21 below the pipeline 1 sinks, the detection components 3 in the limit protection shells 4 on both sides can monitor the sinking of the pipeline 1. A protective plate 38 is fixedly provided on the bottom wall of the limit protection shell 4 directly below the sinking detection rod 34 to reduce damage to the bottom of the limit protection shell 4.

[0032] The working principle of the pipeline settlement detection device of the present invention is as follows: when the buried pipeline 1 settles, at this time, the pipeline base 21 moves downward together with the pipeline 1, and at this time, the shell 31 of the detection component 3 moves downward at the same time, and the lower end of the settlement detection rod 34 always keeps in contact with the bottom wall of the limit protection shell 4 and the position remains unchanged, that is, the piston plate 32 and the spring 33 move upward relative to the shell 31 and squeeze the liquid, so that the detection moving block 36 moves upward, and the displacement sensor 39 on the top of the settlement detection tube 35 records the rising distance of the detection moving block 36, so that the settlement height of the detection point corresponding to the detection component 3 can be understood, and through multiple groups of detection data, the settlement of a certain range of the pipeline 1 can be analyzed, thereby improving the detection efficiency, and no manual labor, station setting, observation and recording are required during the measurement process, and it is not affected by weather conditions. The device has high detection efficiency, simple structure, low cost of the device, and low maintenance and calibration costs.
