Abstract

The invention discloses an intelligent monitoring system for water inrush in deep tunnel construction, which includes a water inrush monitoring unit, a wireless communication unit and a background management center. The water inrush monitoring unit includes a pressure sensor and a controller for detecting water inrush pressure. The detection signal of the sensor is sequentially sent to the precision differential amplifier circuit, low-pass noise reduction adjustment circuit and filter conversion circuit for processing, reducing the impact of external interference and internal factors of the sensor on pressure detection, improving the accuracy of water pressure data collection, and finally processing The final detection signal is sent to the controller. The controller is used to remotely transmit the collected water pressure data information to the background management center through the wireless communication unit. Thereby effectively reducing the probability of water inrush disasters and ensuring the safety of tunnel construction.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an intelligent monitoring system for water inrush in deep tunnel construction. Background technique [0002] With the development of tunnel construction to large buried depth, long tunnel line and strong karst areas, water and mud inrush disasters have become one of the most common geological disasters in the construction of deep buried tunnels in karst areas, causing huge safety hazards and economic risks to tunnel construction. loss. At present, water inrush monitoring equipment mainly relies on sensors and cameras to form a tunnel monitor to monitor the construction status of the tunnel and the potential possibility of water inrush. The sensors mainly include surrounding rock pressure sensors and seepage water pressure sensors. Detect water pressure or water level data. Due to the different types and degrees of interference in the pressure detection process, for ...
