Definition:

Monitoring equipment in tunneling and underground structures refers to the specialized devices and systems used to measure, record, and analyze various parameters and conditions during the construction, operation, and maintenance of tunnels and underground facilities. It includes a wide range of instruments and technologies designed to monitor geotechnical, structural, environmental, and safety aspects of the project.

Uses/benefits:

Safety: Monitoring equipment helps ensure the safety of workers and the surrounding environment by continuously monitoring factors such as ground movement, structural integrity, gas levels, ventilation, and other potential hazards. It enables early detection of risks and allows for timely interventions to prevent accidents.
Performance evaluation: Monitoring equipment provides data for assessing the performance of tunneling activities, support systems, and structural elements. It helps evaluate the effectiveness of construction methods, identify areas of concern, and optimize designs for future projects.
Risk management: By monitoring parameters such as ground settlement, deformation, water pressure, and gas levels, the equipment helps identify potential risks and allows for proactive risk mitigation measures. It enables project managers to make informed decisions to minimize disruptions and avoid costly damages.
Compliance with regulations: Monitoring equipment assists in meeting regulatory requirements for environmental, health, and safety standards. It helps monitor noise levels, air quality, vibration, and other environmental factors to ensure compliance and minimize impacts on nearby communities.
Data-driven decision-making: The data collected by monitoring equipment serves as a valuable resource for project managers, engineers, and stakeholders. It provides insights into the behavior of the project, facilitates data-driven decision-making, and supports ongoing analysis and optimization efforts.

Specifications:

Sensor technology: Monitoring equipment utilizes various sensor technologies, including accelerometers, strain gauges, inclinometers, pressure transducers, gas detectors, environmental sensors, and more. The selection of sensors depends on the specific parameters to be measured.
Data acquisition and transmission: Monitoring equipment is equipped with data acquisition systems to collect and process data from sensors. The systems may include wireless communication capabilities for real-time data transmission and remote monitoring.
