AI Technical Summary
Existing technologies are insufficient for monitoring the sidewalls of foundation pits, making it difficult to effectively monitor and prevent the collapse of the sidewalls, which affects the construction progress and the safety of surrounding buildings.
The system combines a sidewall insert rod with an infrared transmitter. The infrared transmitter emits a laser beam downwards into the pit, and the signal is reflected by a V-shaped groove to monitor the stability of the pit's sidewall. The receiver plate is fixed to the bottom of the pit by the ground insert rod, enabling precise monitoring.
This improved the sensitivity and reliability of pit sidewall monitoring, enabling timely detection of potential collapse risks and protecting the safety of workers and the surrounding environment.
