Description
Technical Field
[0001] The invention relates to the technical field of foundation pit engineering monitoring, and in particular to an automatic deep horizontal displacement measuring device and a measuring method. Background Art
[0002] As a basic project in urban construction, the deeper the excavation depth of the foundation pit, the higher the requirements for foundation pit safety monitoring. Therefore, the smaller the deformation of the foundation pit retaining structure due to the foundation pit excavation, the better. The deep horizontal displacement of the retaining structure, also known as wall inclinometer, can intuitively show the deformation of the foundation pit. Therefore, continuous monitoring during the foundation pit construction to obtain the change data of the foundation pit retaining structure is an important measure to ensure the safety of the foundation pit construction.
[0003] The deep horizontal displacement of the retaining structure is usually monitored manually. The monitoring personnel use an inclinometer to measure the inclinometer hole in the forward and reverse directions, and then process the measurement data to obtain the change in the deep horizontal displacement of the retaining structure. On the one hand, it is usually necessary to conduct a measurement once a day during the excavation of the foundation pit, which is a heavy monitoring task and high work intensity; on the other hand, the monitoring data has artificial errors and a certain lag. Once a dangerous situation occurs, it is difficult to confirm the deformation of the foundation pit in the first time.
[0004] The mainstream automated inclinometers currently used in the market are divided into fixed and pull-up types. On the one hand, fixed automated inclinometers generally place multiple sensors along the depth direction in the hole to test the data changes at different depths. This is difficult to install, and the errors of individual sensors can easily affect the overall calculation results. The orifice device of the pull-up automated inclinometer is large in size, difficult to install on site, and difficult to protect. On the other hand, the existing automated inclinometers only support single-direction data measurement, and cannot eliminate the measurement errors caused by long-term zero drift, temperature fluctuations, and movement in the hole, resulting in large errors in the measured data.

[0030] In this embodiment, the housing 201 is preferably waterproof and sealed to prevent water from accumulating in the openings from entering the device and causing damage to the electrical components inside the device.
[0031] Combination Figure 5 and Figure 6 As shown, the slide groove 2304 is located at one side of the inner wall of the housing 201 , the slide groove 2304 is installed with a slider 2302 , and the slider 2302 is installed with a pulley 2303 . The slide groove 2304 allows the slider 2302 to move only in the axial direction of the housing 201 .
[0032] Four shaft supports are fixed to the inner wall of the housing 201 by screws, wherein shaft support 202 is used to fix the motor 203; shaft support 204 and shaft support 207 are provided with bearing kits for fixing the rotating shaft 206; and shaft support 208 is used to fix the micro tension sensor 2401.
[0033] The motor 203 is fixed on the side of the shaft support 202 by screws. The motor 203 is connected to the rotating shaft 206, and the rotating shaft 206 is fixed at the center position of the housing through the shaft support 204 and the shaft support 207.

Pulleys 302 are respectively provided at both ends of the support rod 303. A spring is provided between the support rod 303 and the shell 301, so that the support rod 303 rotates around the support rod shaft 304 to open, thereby ensuring that the pulleys 302 at both ends of the support rod 303 are tightly attached to the wall of the inclinometer hole, which not only ensures the balance of the sliding unit in the inclinometer hole, but also ensures that the sensing unit is always in the center position of the inclinometer hole.
