Tunnel fire-fighting system of utilizing slope flowing water and pavement water as water source

Abstract

The invention discloses a tunnel fire-fighting system of utilizing slope flowing water and pavement water as a water source, which comprises a drainage ditch, a longitudinal drainage and seepage ditch, a side ditch, transverse drain pipes, a pavement torrent chute, intercept and drainage ditches and a slop torrent chute, a water filter, a sand sediment trap, a low-position pool, a pump room, a high-position pool and a tunnel fire hydrant which are built near the tunnel; the slope flowing water is as the water source, so that the adequate water storage of a reservoir is ensured, meanwhile, the cost is reduced; the intercept and drainage ditches are built in a plurality of contour lines of a hillside to collect rainwater from a slope surface, so that the water source is collected more conveniently, and the cost is relatively low; meanwhile, the pavement water is collected as the water source to supplement for the slope flowing water, so that the water source is more adequate; the torrent chutes are built to collect the slop flowing water of the intercept and drainage ditches, and the water speed is lowered by the torrent chute which forms an included angle with the intercept and drainage ditch; an energy dissipation dam is arranged between the torrent chutes and the water filter, the water speed is further lowered, and the water filter is protected.

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
