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

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] like figure 1 and figure 2 As shown in the figure, multiple intercepting drainage ditches are built on the mountain break adjacent to the tunnel, and the same intercepting drainage ditch is built along the same contour line of the hillside to collect rainwater and form slope water on the mountain; the water flows along the mountain in the intercepting drainage ditch flow. The ends of all intercepting drainage ditches are collected into the filter pool, and the filter pool is built in a low-lying place near the tunnel. After the sediment settles in the sand sinking well, the clean water will automatically flow from the pipes installed on the upper part of the sand sinking well to the low-level pool at the lower level, and then the clean water will be sent to the high-level pool through the pump room. Since the position of the high-level pool is...

Abstract

The invention discloses a tunnel fire-fighting system using slope surface flowing water as a water source. 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; 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; by arranging a low-position pool, a pump room and a high-position pool, a water pressure can be automatically provided for a tunnel fire hydrant; a pressure sensor is arranged to detect the quantity of sediments in a sand sediment trap and send a wireless alarm signal to a control center of the tunnel fire-fighting system when the sediments are excessive so as to prompt a worker to clear up the sediments in the sand sediment trap and avoid the condition that due to blockage, which is caused by the excessive sediments in the sand sediment trap, of a pipeline communicated with the low-position pool, water cannot be stored in the low-position pool to cause the result that no water can be used for tunnel firefighting.

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 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 a...
