Description
Technical field
The present invention relates to tunnel technical field of fire control, particularly relate to a kind of tunnel fire protection system utilizing cheuch intermountain water water source.
Background technology
Along with the propelling of highway construction, the highway tunnel of mountain area and highlands gets more and more, and highway tunnel, once breaking out of fire, causes consequence serious, therefore, builds tunnel fire protection system extremely necessary.And these tunnels are substantially all among high and steep mountains, away from cities and towns, its water for fire fighting all adopts builds pond retaining to ensure water for fire fighting demand.Because of factor controllings such as topography and geomorphology, geology and precipitation, velocity tunnel fire water supply is collected often more difficult, and water source water yield fraction is low, in addition reservoir existing defects in addressing, construction and management etc., cause pond to seep water, leak and well damage, water for fire fighting requirement cannot be met, even if adopt waterwheel fortune water supply reservoir, because cost is higher, feasibility is lower.
Summary of the invention
In view of this, the invention provides a kind of tunnel fire protection system utilizing cheuch intermountain water water source, by utilizing intermountain water as water source, the water retention capacity of reservoir abundance can be ensured, reduce costs simultaneously.
A kind of tunnel fire protection system utilizing cheuch intermountain water water source of the present invention, comprises gutter and builds check dam, filter, sand sediment trap, low pool, pump house, head-tank and the tunnel fire plug near described tunnel;
Described gutter is built between the mountain valley that described tunnel is contiguous, for collecting intermountain water;
The end in gutter laterally built by described check dam along gutter; Described filter is built in described check dam, and described filter is connected by pipeline and described sand sediment trap; Described sand sediment trap is by being arranged on the pipeline on borehole wall top and described low pool UNICOM; The position of described low pool is lower than described sand sediment trap; Low pool water is extracted in head-tank by described pump house; The position that described head-tank is built is higher than described low pool; Described head-tank is connected in described tunnel fire plug by least two pipelines.
Preferably, the water inlet pipe be connected between described head-tank with tunnel fire plug be coated with eliminate rust, the coating of oil removing or acid-proof; The pool wall top of described low pool is provided with spout hole; Be provided with overflow well near described low pool, store the intermountain water flowed out from the spout hole of low pool; The capacity of described low pool and head-tank is suitable.
Preferably, the gradient that the water inlet pipe between described head-tank and tunnel fire plug rises on fire plug direction, tunnel, the described gradient is for being greater than or equal to 5/1000ths; The water inlet pipe be connected between described head-tank with tunnel fire plug arranges horn mouth down in head-tank one end, and described horn mouth is lower than the lowest water level at least 0.5 meter of head-tank; Described horn mouth and the clear distance at the bottom of head-tank pond are more than or equal to 0.8 times of water inlet pipe caliber, and the clear distance of described flared rim and head-tank pool wall is more than or equal to 1.5 times of water inlet pipe calibers; Clear distance between described two water inlet pipes is more than or equal to 3.5 times of water inlet pipe calibers; Foam or antifreeze cotton-wool is wrapped up outside the water inlet pipe be connected between described head-tank with tunnel fire plug.
The present invention has following beneficial effect:
Tunnel fire protection system of the present invention, by utilizing intermountain water as water source, can ensure the water retention capacity of reservoir abundance, reducing costs simultaneously; The end in gutter built by employing check dam, and in gutter, water is tackled by check dam and stores, and in season short of rain, because check dam water retention capacity is comparatively large, can store more intermountain water; By arranging low pool, pump house and head-tank, automatically hydraulic pressure can be provided to tunnel fire plug.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of tunnel fire protection system of the present invention.
Fig. 2 is the structural representation of check dam in the present invention.
1-check dam, 2-filter.
Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
The intermountain water flowed down from hillside is collected in gutter, intermountain water flows along gutter, after flowing to check dam, blocked by the check dam laterally built, in check dam, filter is set, bulk sandstone in intermountain water and branch leaf etc. are filtered out, sand sediment trap is flowed to again by pipeline, silt in intermountain water is after sand sediment trap precipitation, the low pool of the pipeline automatic stream lower that clear water is arranged from sand sediment trap borehole wall top, by pump house, clear water is delivered to head-tank again, because the position of head-tank is higher than the position of tunnel fire plug, the automatic mineralization pressure of water in fire plug.The height of head-tank is arranged according to the hydraulic pressure of tunnel fire plug.For ensure fire plug uninterruptedly supply water, the water inlet pipe of one group of fire plug should be no less than two, when wherein one damage time, remaining water inlet pipe is still by whole water supply volume.
For ensureing that the water yield is sufficient, quite, after the water of head-tank is used up, low pool can to head-tank moisturizing once for the capacity of described low pool and head-tank, and what can ensure to provide two head-tank water yields to fire plug in a fire-fighting uses water.
In order to not make water inlet pipe inner accumulated air, the gradient that the water inlet pipe between head-tank and tunnel fire plug rises on fire plug direction, tunnel, the gradient is for being greater than or equal to 5/1000ths.
For ensureing that the water of head-tank can flow in water inlet pipe automatically, the water inlet pipe be connected between head-tank with tunnel fire plug arranges horn mouth down in head-tank one end, and described horn mouth is lower than the lowest water level at least 0.5 meter of head-tank.Horn mouth and the clear distance at the bottom of head-tank pond are more than or equal to 0.8 times of water inlet pipe caliber, and the clear distance of described flared rim and head-tank pool wall is more than or equal to 1.5 times of water inlet pipe calibers; Clear distance between described two water inlet pipes is more than or equal to 3.5 times of water inlet pipe calibers.
The water inlet pipe of Cold mountain area must have anti-frost protection measure, wraps up foam or antifreeze cotton-wool outside the water inlet pipe be therefore connected between head-tank with tunnel fire plug.
Water inlet pipe should take anti-corrosion measure, the water inlet pipe be connected between head-tank with tunnel fire plug be coated with eliminate rust, the coating of oil removing or acid-proof.For underground buried tube, preservative treatment can be carried out with bitumen insulation.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
