FIELD: construction.
SUBSTANCE: invention relates to road construction, namely to bridges safety systems. Bridge safety ensuring device connecting two water area shores with bridge approaches on both sides, enclosed by U-shaped fences, includes operator workstation consisting of system unit, display, keyboard and “mouse” type manipulator, as well as security alarm module with guard board, which output is connected to system unit, and inputs are connected with safety control sensors, as well as radio locator control module, containing at least two radio locators connected via radio locator controller with system unit and installed on bridge approaches, also comprises sonar unit, containing sonar controller connected with sonars made in remote (underwater) part, consisting of active receiving-emitting modules combined into sections with length from 100 to 1,000 m each and connected by main cable with power supply sources, providing radiation and reception of probing signal, processing signal information, transmission of information on stationary surface observation point.
EFFECT: enabling bridge protection on water area side and situation awareness on large length bridges.
