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

Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0017] The seepage pipe collects the tunnel gushing water in the soil and rocks on the roof of the tunnel, and the tunnel gushing water flows down the seepage pipe to the side ditches on both sides of the tunnel entrance; at the same time, when it rains, the accumulated water on the road flows into the side ditches and the central drainage ditch, and the side ditches and the central drainage ditch The water from the side ditch is collected into the side ditch on one side through the horizontal drainage pipe, and the water collected from the side ditch is introduced into the grit chamber through the drainage ditch built on the side of the road. The pipes installed on the upper part of the well wall of the sand sinking well automatically flow to the lower pool, and then the clean water is sent to the high pool through the pump room. Since the position of the ...

Abstract

The invention discloses a tunnel fire-fighting system employing tunnel surging water as a water source. The tunnel fire-fighting system is characterized by comprising a seepage pipe, a central draining ditch, a side ditch, a transverse draining pipe, a sand sediment trap, a low-level water pool, a pump room, a high-level water pool and a tunnel fire hydrant, wherein the sand sediment trap, the low-level water pool, the pump room, the high-level water pool and the tunnel fire hydrant are built nearby a tunnel. By utilizing the tunnel surging water as the water source, water can be conveniently taken, a water taking facility is simple, and the cost is reduced; through the adoption of the low-level water pool, the pump room and the high-level water pool, water pressure can be automatically provided 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 tunnel water as a water source. 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 water seepage, leakage ...
