Tunnel fire-fighting system taking road surface water and tunnel surge water as water sources

Abstract

The invention discloses a tunnel fire-fighting system taking road surface water and tunnel surge water as water sources. The tunnel fire-fighting system comprises a drainage ditch, a longitudinal drainage and seepage ditch, a side ditch, a transverse drainage pipe, a road surface stream trough, a water quality sensor, a switching mechanism, a filtering pond, a sand sediment trap, a low-position water pond, a sewage pond, a pump room, a high-position water pond and a tunnel fire hydrant, wherein the filtering pond, the sand sediment trap, the low-position water pond, the sewage pond, the pump room, the high-position water pond and the tunnel fire hydrant are built nearby a tunnel. Due to the fact that road surface water and the tunnel surge water serve as the water sources, the water sources are more enough, water is convenient to fetch and the cost is reduced; due to the fact that the low-position water pond, the pump room and the high-position water pond are arranged, water pressure can be automatically provided for the tunnel fire hydrant; the switching mechanism is controlled to conduct the water inlet to the pump room or the sewage pond by judging whether the water sources are polluted the water quality sensor, so corrosion of the tunnel fire hydrant and a connecting pipeline due to a pollution source is avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel fire protection, in particular to a tunnel fire protection system using road surface water and tunnel water gushing 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, result...

AI Technical Summary

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
