Tunnel vault settlement monitoring and early warning device and method

Abstract

The invention discloses a tunnel vault settlement monitoring and early warning device and method. The tunnel vault settlement monitoring and early warning device comprises a shell, and a first processor and a pull rope sensor are arranged in the shell; the pull rope sensor is provided with a remote controller in a matched mode and used for achieving remote control. The first processor is connectedwith the pull rope sensor through a signal line and used for obtaining the telescopic amount of a pull rope in the pull rope sensor. A fluorescent screen with adjustable brightness is arranged on theouter surface of the shell; the fluorescent screen is connected with the first processor, the scale format displayed by the fluorescent screen is the same as the scale format of the indium steel ruler, after the stretching amount of the pull rope of the pull rope sensor is processed by the first processor, the scale of the tunnel vault elevation after the displacement distance of the pull rope isdisplayed on the fluorescent screen, and the scale of the level gauge observation area is the actual elevation of the tunnel vault; a lithium battery is further arranged in the shell and connected with the pull rope sensor, the fluorescent screen and the first processor through wires. The device is easy to operate and high in precision, and the working efficiency and convenience of workers are improved.

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
