Fire stopping system of underground common utility tunnels having fire stopping room

摘要

The present invention relates to a fire protection compartment fire protection system of an underground co-operation zone that can block flame propagation in the event of a fire in the underground co-operation zone. In constructing underground co-located facilities that jointly accommodate underground underground facilities such as facilities and sewerage systems, a firewall that fireproofs the underground co-ground is installed to prevent the spread and spread of flames. It can block the propagation of flame for a long time, and it is excellent in fire resistance, and it can be installed in existing joint holes as well as new joint holes, so it is very economical. Reduce installation costs, reinforce fragility of flames, and expand volume It can actively block the flame to the refractory material, to detect the installation of fire doors that close automatically the passage has an effect to be able to completely avoid the transfer and diffusion of the flame.
