A device and method for tunnel vault settlement monitoring and early warning

Abstract

The invention discloses a tunnel vault subsidence monitoring and early warning device and method, which includes a housing in which a first processor and a rope sensor are arranged; the rope sensor is equipped with a remote controller for remote control Control; the first processor is connected to the pull rope sensor through a signal line, and is used to obtain the stretching amount of the pull rope in the pull rope sensor; the outer surface of the housing is provided with a fluorescent screen with adjustable brightness, and the fluorescent screen is connected to the first processor, and the fluorescent screen The scale format of the display scale is the same as the scale format of the indium steel scale. After the stretching amount of the pull rope of the pull rope sensor is processed by the first processor, the scale scale of the tunnel vault elevation after the distance of the pull rope displacement is displayed on the fluorescent screen, and the scale of the observation area of ​​the level gauge The scale is the actual elevation of the tunnel vault; the housing is also provided with a lithium battery, which is respectively connected to the rope sensor, the fluorescent screen, and the first processor through wires. The invention has simple operation and high precision, and improves the work efficiency and convenience of staff.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a tunnel vault settlement monitoring and early warning device and method. Background technique [0002] With the continuous development of the economy, the continuous improvement of comprehensive national strength and the continuous application of high-tech, the construction of tunnels and underground engineering in my country has achieved unprecedented development. In order to ensure the safety of tunnel construction, real-time and accurate monitoring and measurement of tunnels is very important. of. At present, there are many deficiencies in tunnel vault settlement monitoring, for example: ① the accuracy of the indium steel ruler is relatively high, but the length of the indium steel ruler is too low, which cannot meet the large-span monitoring requirements of the tunnel section; ② during the tunnel vault settlement monitoring process, the The light inten...

AI Technical Summary

Problems solved by technology

At present, there are many deficiencies in tunnel vault settlement monitoring, for example: ① the accuracy of the indium steel ruler is relatively high, but the length of the indium steel ruler is relatively low, which cannot meet the large-span monitoring requirements of the tunnel section; ② during the tunnel vault settlement monitoring process, the The light intensity requirements of the tunnel are high, and too strong or too weak light will affect the monitoring results and increase the difficulty of monitoring; ③The measurement form is generally in the form of measuring point hook + steel tape measure + plumb weight + telescopic rod. It is not easy to install and retract and fold during engineering measurement, and it will cause large errors after damage and replacement
