Abstract

The invention discloses a laser monitoring and alarming system for deep foundation pit displacement. The laser monitoring and alarming system comprises a laser monitoring system, wherein the laser monitoring system is connected with a processing system, and the processing system is connected with an automatic alarming system. According to the abovementioned scheme, the laser monitoring and alarming system has the beneficial effects of simple structure and rational design, and can be used for overcoming operation and judgment errors caused by subjective factors and objective factors of a person, monitoring in real time around the clock, monitoring alarming fault affected by subjective reasons and objective reasons can be monitored, and finding out potential safety hazards immediately and sending an alarm within the shortest time.

Description

technical field [0001] The invention relates to a deep foundation pit displacement monitoring system, in particular to a deep foundation pit displacement laser monitoring and alarm system. [0002] Background technique [0003] A foundation pit refers to the space below the ground excavated for the construction of the foundation and basement of a building or structure. Generally speaking, a deep foundation pit refers to a foundation pit with an excavation depth greater than or equal to 5m. During building construction, the displacement monitoring of the side wall of the foundation pit is very important for the construction safety and the safety of the surrounding buildings. The current deep foundation pit displacement monitoring is that a number of workers go to the edge of the foundation pit every day, monitor the deep foundation pit displacement through a total station, and then manually organize and record it. There are operational and judgment errors caused by subjectiv...
