Integrated pipe gallery (called "common ditch" in Japan, and "common pipeline" in Taiwan), It is the underground urban pipeline comprehensive corridor, that is, a tunnel space is built underground in the city, which integrates various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, and has special inspection ports, hoisting ports and monitoring systems. The implementation of unified planning, unified design, unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city.
First: Features
Power cable fire accidents due to the large number of power cables in the integrated pipeline gallery, dense laying, and heating of the power cables under operating conditions, and the special structure and relative concentration of cables in the cable trenches. When a cable fails, it will cause surrounding areas. Other cables caused major fire accidents.

Second: The fire characteristics of the integrated pipe gallery
　　

Hidden Sex

underground integrated pipe The corridor is underground, unattended, and it is not easy to be found in the event of fire.

Complexity

underground integrated pipe There are many corridors and pipelines, and municipal pipelines such as water supply, drainage, electricity, communication, heating, radio and television, and gas are integrated.

Linkage

Electrical fire , Gas leak and explosion…… It is precisely because of the complexity of the underground comprehensive pipe gallery that the uncertainty and diversity of the hazard sources are caused. If a security incident occurs, it is very likely to cause a "chain reaction".

Difficult to save

underground integrated pipe The corridor space is closed, and pipelines and cables are stacked and arranged in a concentrated manner. Fires will generate a large amount of high temperature, smoke and toxic gases, and it is difficult to implement general public fire protection measures.

Third: Smart Fire Fighting Solution:
1) Establish a set of "perception-assessment-warning-disposal-optimization" fire prevention and control solutions combined with intelligent iterative optimization and improvement to continuously improve the fire risk self-prevention and control capabilities of key firefighting units;
Perception: integrated monitoring of smoke, temperature and fire; remote visual supervision; mobile phone monitoring;
Assessment: regional fire risk assessment; single building fire risk assessment;
Early warning: early warning of fire area; early warning of unit area fire; emergency preparation plan to assist decision-making
Disposal: call the fire control center; management of fire-fighting duty personnel; fire-prevention monitoring management; fire-fighting system start-up management
Optimization: accident data analysis; fire protection publicity and education; fire protection supervision improvement; fire simulation drill
　　

2) Use 5G Internet of Things information technology, fire technology, New technologies for smart firefighting achieve the seven goals of comprehensive perception, dynamic monitoring, intelligent early warning, unified command, rapid disposal, precise supervision, and data analysis, and effectively improve the fire prevention and control capabilities and actual command level of fire rescue agencies and key firefighting units themselves , Create a good fire safety environment for social and economic development, and escort the continuous stability of the society and the sustainable health of the people.
Comprehensive perception: Comprehensive perception of smoke, temperature, and fire
All-weather monitoring: HD camera 360° all-weather monitoring
Intelligent warning: fire control center warning; wireless terminal transmission warning; mobile terminal warning
Scientific command: Make scientific decisions through visual monitoring; initiate relevant emergency preparedness plans;
Quick disposal: emergency evacuation of personnel; activation of fire extinguishing system;
Precision supervision: precise fire area scope; division of risk areas to organize evacuation in an orderly manner;
Data analysis: risk assessment; simulation exercise
