Tunnel fire system with water sources which are slope surface flowing water and road surface water

Abstract

The invention discloses a tunnel fire system with water sources which are slope surface flowing water and road surface water. The tunnel fire system comprises a drainage ditch, a longitudinal drainage ditch, a side ditch, a transverse drainage pipe, a road surface rapid flow groove, an intercepting drainage ditch, a filter pond, a sand sediment trap, a low-position pond, a pump house, a high-position pond and a tunnel fire hydrant. The filter pond, the sand sediment trap, the low-position pond, the pump house, the high-position pond and the tunnel fire hydrant are constructed near a tunnel. The tunnel fire system has the advantages that the water sources are the slope surface flowing water and the road surface water, accordingly, sufficient water storage of reservoirs can be guaranteed, and the cost can be reduced; the intercepting drainage ditch is built on a plurality of contour lines of slopes to collect rainwater on slope surfaces, accordingly, the water resources can be conveniently acquired, and the tunnel fire system is low in cost; the road surface water is used as the water source for supplementing the slope surface flowing water, and accordingly the water sources are sufficient; the tunnel fire system is provided with the low-position pond, the pump house and the high-position pond, and accordingly water pressures can be automatically generated for the tunnel fire hydrant.

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...

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
