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

[0014] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] The drainage ditch collects the mountain water flowing down from the hillside, and the mountain water flows along the drainage ditch. When it flows to the dam, it is blocked by the horizontally built dam. The branches and leaves are filtered out, and then flow to the sand well through the pipeline. After the sediment in the mountain water settles in the sand well, the clean water automatically flows from the pipeline set on the upper part of the sand well wall to the low-level pool, and then the clean water is pumped through the pump room. It is sent to the high-level pool. Since the position of the high-level pool is higher than that of the tunnel fire hydrant, the water in the fire hydrant automatically forms pressure. The height of the elevated pool is set according to the water pressure of the tunnel fire hydrant. In order to ensure the unin...

Abstract

The invention discloses a tunnel fire-fighting system of utilizing water of valleys and between mountain as a water source, which comprises a drainage ditch and a water retaining dam, 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; water of valleys and between mountain is used to be as the water source, so that the adequate water storage of a reservoir is ensured, meanwhile, the cost is reduced; the water retaining dam is built at the tail end of the drainage ditch, the water in the drainage ditch is intercepted and stored by the water retaining dam; in a dry season, more water between mountains can be stored by virtue of the relatively high water storage of the water retaining dam; the low-position pool, the pump room and the high-position pool are arranged, so that the 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 utilizing water sources between valleys and mountains. Background technique [0002] With the advancement of highway construction, there are more and more highway tunnels in mountainous and plateau areas. Once a fire occurs in a highway 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 mountains and mountains, far away from the towns, and the fire water is used to build a pool to store water to ensure the fire water demand. Due to factors such as topography, geology and precipitation, it is often difficult to collect fire water sources for high-speed tunnels, and the water supply guarantee rate is low. In addition, there are defects in the site selection, construction and management of the reservoir, resulting in water se...
