Problems solved by technology

However, isolation equipment is installed in the radial direction of the tunnel. Due to the wide width of the tunnel, it is obviously not suitable to use traditional fire doors or protective shutter doors; when a fire occurs in the tunnel, the smoke will spread along the longitudinal direction of the tunnel. The inability of vehicles to enter will cause the fire to spread further, causing property damage and personal injury

Embodiment Construction

[0010] Such as figure 1 As shown, the fire separation facilities in the tunnel provided by this embodiment include sprinklers (1), U-shaped pipes (2), fixed pipes (3), branch pipes (4), deluge valves (5), fire controllers (6 ), main pipeline (7), smoke sensor (21), main valve (8), booster pump (9), water storage tank (10).

[0011] When a fire breaks out in a certain section of the tunnel, the smoke sensor detects the fire signal and transmits the fire signal to the fire controller. The fire controller starts the fire booster pump and opens the deluge valve corresponding to the fire area. The waterproof curtain sprinkler forms a fire-proof separated water curtain at both ends of the fire area to control the fire within the area and effectively prevent the fire from spreading.

Abstract

The invention discloses a fireproof separation facility in a tunnel. The fireproof separation facility is characterized by comprising a spraying head (1), a U-shaped pipe (2), a fixing pipe (3), a branch pipe (4), a deluge valve (5), a fire disaster controller (6), a main pipeline (7), a smoke sensor (21), a main valve (8), a pressurizing pump (9) and a water storing pool (10). The fireproof separation facility well solves the problem that no fireproof separation facility exists in the longitudinal direction of the tunnel in the prior art.

Description

technical field [0001] The invention relates to a fire separation facility in a tunnel. Background technique [0002] When vehicles are blocked in the tunnel and fire engines cannot enter, if a fire occurs, in order to prevent the spread of the fire and ensure the safe evacuation of personnel, the fire must be controlled in a certain area, especially when the fire is relatively large. However, isolation equipment is installed in the radial direction of the tunnel. Due to the wide width of the tunnel, it is obviously not suitable to use traditional fire doors or protective rolling doors; when a fire occurs in the tunnel, the smoke will spread along the longitudinal direction of the tunnel. If the fire The inability of vehicles to enter will cause the fire to spread further, causing property damage and personal injury. Contents of the invention [0003] In view of the above problems, the present invention provides a fire separation facility in a tunnel. [0004] In order t...
