A kind of underground urban comprehensive pipe gallery system and its fire extinguishing method

Abstract

The invention discloses an underground urban comprehensive pipe gallery system. The underground urban comprehensive pipe gallery system comprises an urban fire protection monitoring system arranged in an urban fire protection control center, a fire detecting and automatic alarming system arranged in an urban underground pipe gallery, and a fire extinguishing system arranged in the urban underground pipe gallery. The urban fire protection monitoring system comprises a main monitoring system arranged in the urban fire protection control center, and a plurality of secondary monitoring systems which are arranged in a plurality of secondary fire protection control centers and connected with the main monitoring system. The fire extinguishing system comprises high-pressure water mist fire extinguishing devices which are arranged in the urban underground pipe gallery and connected with a fire protection water pipeline, and portable fire extinguishers arranged in the urban underground pipe gallery at intervals. The high-pressure water mist fire extinguishing devices are arranged in a dotted manner, and the portable fire extinguishers are arranged at intervals. According to the underground urban comprehensive pipe gallery system, the response speed is increased by means of multi-level monitoring on a fire fighting system; and the dotted high-pressure water mist fire extinguishing devices and the portable fire extinguishers are arranged in cooperation, so that the fire fighting equipment mounting cost is reduced, and common resources are saved.

Description

technical field [0001] The invention relates to the technical field of urban underground pipe gallery, in particular to an underground comprehensive pipe gallery system and a fire extinguishing method thereof. Background technique [0002] Urban underground comprehensive pipe gallery, that is to build a tunnel space underground in the city, integrates various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, and has special inspection ports, hoisting ports and monitoring systems. Unified planning, unified design, unified construction and management are important infrastructure and "lifelines" to ensure urban operation. Once a fire occurs in the underground integrated pipe gallery, it will bring huge property losses and bring great inconvenience to people's lives. Therefore, it is particularly important to make an all-round arrangement for the urban underground urban integrated pipe gallery system. [0003] The fire extinguis...

AI Technical Summary

Problems solved by technology

However, due to the huge urban underground comprehensive pipe gallery system, if it is necessary to cover the entire underground urban pipe gallery in a full range, a large number of high-pressure water mist fire extinguishing devices are required, and the high-pressure water mist fire extinguishing device itself is relatively expensive, and the input cost is high, which is not conducive to the economy. Improvement of benefits; at the same time, the probability of fire at each location in the underground urban pipe gallery is not the same. If high-cost high-pressure water mist fire extinguishing devices are used in places with different fire probability, it will inevitably cause waste of resources. Design a Reasonably arranged underground urban pipe corridor fire protection system is particularly important
