A fire monitoring and fire extinguishing method applied to cable-stayed bridges

Abstract

The invention provides a fire monitoring and fire extinguishing method applied to cable-stayed bridges. It solves the technical problem that a fire accident occurring on the existing cable-stayed bridge cannot be quickly extinguished. This is a fire monitoring and fire extinguishing method applied to a cable-stayed bridge. The fire monitoring and fire extinguishing method includes the following steps: S1, turn on the power, and monitor the environment of the cable-stayed bridge deck in real time through the sensor control unit; S2, discover the fire : S3, the fire extinguishing step: S4, the fire extinguishing is completed; S5, the maintenance personnel clean up the fire site, and the sensing control unit continues to monitor. The invention can quickly extinguish the fire accidents on the cable-stayed bridge.

Description

technical field [0001] The invention belongs to the technical field of fire protection of cable-stayed bridges, and relates to a fire monitoring and fire-extinguishing method applied to cable-stayed bridges. Background technique [0002] Bridge transportation is an important part of my country's road transportation. As more transportation vehicles have been put into use in recent years, the increase in bridge traffic has also caused a significant increase in the probability of traffic accidents, especially when the vehicles carry flammable and When objects are exploded, fire accidents are also easy to occur on the bridge deck. [0003] The cable-stayed bridge is composed of cables, cable towers, main girders, and bridge deck. The load of the bridge deck is transmitted to the cables through the main girder, and then to the cable towers. The cable-stayed bridge is an important modern large structure. The form of spanning bridges, especially when erecting super-large bridges wi...

AI Technical Summary

Problems solved by technology

[0004] Fire accidents in cable-stayed bridges mainly have the following characteristics: due to the unclear flammability of vehicles and cargo, and the unknowable degree of traffic accidents, the nature of bridge fires is highly uncertain; when a fire accident occurs, rescue The difficulty is high, and it takes a long time for emergency vehicles to arrive at the scene; it is difficult to put out fires in municipal bridge projects, and traffic congestion is usually formed, making it difficult for rescuers to approach the fire source

Generally speaking, when a fire breaks out on a bridge, it takes a certain amount of time for professional firefighters and rescuers to arrive at the fire scene after the fire alarm facilities respond, and missing the best time to put out the fire causes the fire to further expand
