Embodiment 1

[0033] Such as Figure 1-4 As shown, the tunnel fire water supply dual supply system of this embodiment supplies water to the fire pool 1 through two water supply systems, specifically, the two water supply systems are: differential pressure water supply system 2 and pump water supply system 3 . Among them, the fire pool 1 is used to provide fire water; specifically, as figure 2 As shown, a water level signal device 14 is provided in the fire-fighting pool 1, and the water-level signal device 14 is provided with three sensing water levels for sensing whether the water level in the fire-fighting pool reaches the highest threshold water level 15, the lowest threshold water level 16 and the normal working water level 17, The normal working water level 17 is between the highest threshold water level 15 and the lowest threshold water level 16 . In addition, the bottom of the fire fighting pool 1 is provided with a water outlet pipe 12, and the water outlet pipe 12 is provided wit...

Embodiment 2

[0040] The difference between the tunnel fire-fighting water supply system of this embodiment and the first embodiment is that:

[0041] Such as Figure 5 As shown, the differential pressure water supply unit also includes a spare water pipe 26 for communicating with the water storage sedimentation tank and the fire-fighting pool; Specifically, the communication position of the standby water delivery pipe 26 and the water storage sedimentation tank is lower than the communication position of the water supply delivery pipe and the water storage sedimentation tank, so that when the water supply opening and closing valve of the storage tank on the water supply delivery pipe is opened, only the water storage The water in the sedimentation tank above the connection position between the water supply pipe and the water storage sedimentation tank is supplied to the fire fighting pool, and the water in the water storage sedimentation tank below the connection position between the water...

Abstract

The invention belongs to the technical field of tunnel fire-fighting, and particularly relates to a tunnel fire water supply double-supply system which comprises a fire-fighting pool, a mountain massif drainage ditch located above the fire-fighting pool, a well located under the fire-fighting pool, a differential-pressure water supply unit for utilizing differential pressure for supplying water inthe mountain massif drainage ditch to the fire-fighting pool, and a pump type water supply unit for utilizing pump pressure for supplying water in the well to the fire-fighting pool. According to thetunnel fire water supply double-supply system provided by the invention, impounded water of a mountain massif is fully utilized, so that the recycling of the impounded water of the mountain massif isimproved, and a water saving effect is achieved; and the system mainly utilizes the impounded water of the mountain massif and is seldomly suppled with water through a submerged pump, so that the energy consumption and the power consumption are remarkably reduced, and a remarkable energy saving effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of tunnel fire protection, and in particular relates to a dual water supply system for tunnel fire protection. Background technique [0002] As a long tunnel, it is usually required to set up an independent fire water supply system, and how to ensure sufficient fire water supply has always been the top priority of tunnel fire management. Conventional fire-fighting water in tunnels generally uses submersible pumps to draw water from wells in nearby mountain streams and supply water to fire-fighting pools. For example, the high-pressure water device for tunnels disclosed in the patent document with publication number CN 203755389U. A water level signal device will be installed in the fire pool. When the water level in the pool reaches the normal use level, the submersible pump will automatically shut down; when the water level is at a low level, the submersible pump will start to supply water to the fire pool....
