AI Technical Summary

Technical Problem

Existing fire protection design codes are ill-suited to the complex spatial structures of deep underground caverns, resulting in inadequate fire safety and evacuation plans, and an inability to effectively control the spread of fire and ensure personnel safety.

Method used

Multiple fire control zones are divided within the deep underground cavern, firewalls and fire doors are installed to form independent fire-resistant compartments, and safe evacuation routes and life-saving cabins are designed to ensure that the fire does not spread and that personnel can be evacuated quickly in the event of a fire.

Benefits of technology

It effectively controls the spread of fire, provides safe evacuation routes, and ensures that personnel can quickly evacuate deep underground caverns in emergencies, thereby improving the fire safety and evacuation efficiency of deep underground caverns.

Abstract

This utility model discloses a fire safety and personnel evacuation facility for deep underground caverns. The deep underground cavern space is divided into multiple fire control zones. Different experimental halls correspond to different fire control zones, with each experimental hall constituting one or more fire control zones. Each service tunnel is an independent fire control zone, and each auxiliary tunnel is divided into two or more fire control zones. Firewalls are installed between adjacent fire control zones. External safety exits are provided at both ends of the auxiliary tunnels where they connect to drainage and traffic tunnels. Each fire control zone has at least two internal safety exits, and adjacent fire control zones are connected through these internal safety exits, which include fire doors installed on the firewalls. This solution, while meeting the functional requirements of underground spaces, provides a method for dividing fire control zones and setting up safety exits, thus solving the problem of controlling the spread of fire in underground spaces.
