Pipeline fire prevention smoke suppression device for underground pipe gallery

Abstract

The invention discloses a pipeline fire prevention smoke suppression device for an underground pipe gallery. The pipeline fire prevention smoke suppression devices are mounted in pipeline channels ofan underground comprehensive intelligent pipe gallery in a distributed manner; a pipeline fire prevention component is formed through combination of a plurality of independent frame body structures; at least two grid units are arranged in each of the frame body structures; a fire prevention grid frame and a frame clamping groove for placing the fire prevention grid frame are arranged between everytwo adjacent grid units; and the space of each of the grid units is used for collecting pipes in the pipeline. The pipeline fire prevention smoke suppression device is simple in structure, and a plurality of pipeline fire prevention smoke suppression devices can be conveniently combined for application. In addition, honeycomb core plate structures and external porous steel plates are arranged inthe fire prevention grid frames, and the core plates are filled with polymers and inorganic salt particulate matters, so that on one hand, effective flame retardance and smoke suppression are carriedout to stop oxygen supply, and on the other hand, smoke in the fire disaster area can effectively diffuse and be collected to carry out site disposal.

Description

Technical field: [0001] The invention relates to the technical field of underground pipe corridors, in particular to a pipeline fire and smoke suppression device for underground pipe corridors. Background technique: [0002] With the rapid development of the urban networked municipal pipe network system, repeated excavation of roads due to pipeline expansion, renewal, maintenance, etc. is very common, which not only causes inconvenience to the normal life of residents, but also brings environmental pollution, noise pollution and Other social costs such as pipeline crossing damage, urban traffic congestion, and loss of commercial interests have increased significantly, which has become a bottleneck restricting urban infrastructure development and environmental improvement. In addition, due to the newly built subways in major cities, the original pipeline network facilities are destroyed or pipeline reconstruction often occurs. In this context, as a new model that effectively solv...

AI Technical Summary

Problems solved by technology

[0004] However, because there are currently many lines and pipelines involving heat energy, heat supply, and heat in the interior of the pipe gallery, such as electricity, communication, gas, and heating, and the isolation between them is relatively incomplete. External pressure, vibration and other influences can also cause accidental leakage, aging and other factors to cause smoke and fire, which can easily cause serious consequences

Smoke detection and alarm devices are often designed in the pipelines of existing underground comprehensive utility corridors, but there are still deficiencies in the response measures after a fire occurs
