Tunnel fire-fighting system using slope surface flowing water and pavement water as water sources

Abstract

The invention discloses a tunnel fire-fighting system using slope surface flowing water and pavement water as water sources. The tunnel fire-fighting system is characterized by comprising a drainage ditch, a longitudinal seepage and drainage ditch, a side ditch, a transverse drainage pipe, a pavement jet stream trough, drain dykes and a filter bed, a sand sediment trap, a low-position pool, a pump room, a high-position pool and a tunnel fire hydrant which are built near a tunnel, wherein the slope surface flowing water is used as the water source, so that sufficient water retention capacity of a reservoir can be ensured and meanwhile, cost is reduced; the drain dykes are built on a plurality of contour lines of a mountain slope to collect slope surface rainwater, so that the water source is more convenient to collect and cost is low; meanwhile, pavement water is used as the water source and supplements the slope surface flowing water, so that the water sources are more sufficient; a water quality is matched with a switching mechanism and when the water quality is unqualified, sewage is drained into a sewage pool and qualified water is drained into the high-position pool so as to avoid corrosion of acidic materials in the sewage to the fire hydrant and a pipeline.

Description

technical field [0001] The invention relates to the technical field of tunnel fire protection, in particular to a tunnel fire protection system using slope water and road surface water as water sources. Background technique [0002] With the advancement of road construction, there are more and more road tunnels in mountainous and plateau areas. Once a fire occurs in a road tunnel, the consequences will be serious. Therefore, it is extremely necessary to build a tunnel fire protection system. These tunnels are basically located in the high mountains and far away from towns, and the water for fire fighting is to build pools to store water to ensure the demand for fire water. Due to topography, geology, precipitation and other factors, it is often difficult to collect fire-fighting water sources in high-speed tunnels, and the guarantee rate of water source water is low. In addition, there are defects in the location, construction and management of the reservoir, resulting in wa...

Problems solved by technology

Due to topography, geology, precipitation and other factors, it is often difficult to collect fire-fighting water sources in high-speed tunnels, and the guarantee rate of water source water is low. In addition, there are defects in the location, construction and management of the reservoir, resulting in water seepage, leakage and damage to the reservoir Seriously, it cannot meet the fire water requirements. Even if water trucks are used to replenish the reservoir, the cost is high and the feasibility is low
