Description

Technical Field

[0001] The utility model belongs to the technical field of fire protection facility management, and in particular relates to a fire protection facility management system for a highway tunnel. Background Art

[0002] Highway tunnels are generally flat and large-section, and are mostly designed with double holes. Compared with the usual road and bridge structures, tunnel structures are relatively closed, with narrow spaces, and poor brightness, ventilation, and climate in the tunnel. Therefore, once a fire accident occurs in a tunnel that is open to traffic, it is easy to cause traffic congestion, and people and vehicles in the tunnel face difficulties in evacuation, which is not conducive to timely rescue measures; with the continuation of the fire accident, the burning, high temperature or explosion in the tunnel can easily cause hypoxia, poisoning, or object collision and other malignant accidents to the personnel on site. Therefore, in the early stage of a fire, the fire-fighting facilities in the tunnel can monitor and detect the fire accident in time, and the personnel on site can promptly use fire hydrants, fire extinguishers and other equipment to extinguish the fire in the bud stage, quickly and effectively control and eliminate the fire accident, and reduce the damage caused by the fire accident.

[0003] Combined with the characteristics and management status of tunnel fire safety, highway tunnel fire protection construction is designed strictly in accordance with national safety standards, focusing not only on tunnel structural safety, but also on additional safeguards to ensure operational safety. For example, in order to improve the fire resistance of the building itself in the tunnel, fire retardant coatings are added to the tunnel walls and ancillary buildings to improve the wall's ability to withstand high temperatures. At the same time, the decorative materials in the tunnel are designed to release no toxic gases at high temperatures to avoid harm to stranded personnel. However, due to the special narrow space of the tunnel, when a fire accident occurs, it is often impossible to extinguish the fire in a timely and rapid manner. Utility Model Content
