The invention discloses a method for mounting and applying a road, bridge and
tunnel safety comprehensive detection, monitoring and early warning device. The device comprises components as follows: control processors, a central processor, warning devices, side slope and heading slope displacement detection sensor, a bridge entrance superelevation and
overweight detection sensor, a bridge structure displacement and gravity detection sensor, a bridge anti-
collision detection sensor, a tunnel lining transformation detection sensor, a
wind power detection sensor, a rain,
snow,
fog visibility,
humidity and temperature detection sensor, road, bridge and tunnel
virtual model or
entity model, a memory and the like. The device can achieve all-round and full-time detection, monitoring and early warning of roads, bridges, tunnels and the like, stores data in a management and maintenance center for analysis, executes warning in a
pile number position corresponding to the road, bridge and tunnel model, achieves
network data share, and detects, monitors and manages the facilities at any nodes of a network, facilitates the analysis of safety accidents, timely processes potential hazards, reduces accidents, and has functions of intelligent traffic,
intelligent management, intelligent maintenance and the like.
