Further, also comprise filter, be arranged between sand sediment trap and described gutter; The pool wall top of described low pool is provided with spout hole; Be provided with overflow well near described low pool, store the water flowed out from the spout hole of low pool.
Preferably, the capacity of described low pool and head-tank is suitable, for head-tank moisturizing; The gradient that 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 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 present invention has following beneficial effect:
Tunnel fire protection system of the present invention, by utilizing Tunnel Gushing as water source, can conveniently fetch water, and water intake facilities is simple, reduces costs; 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 in tunnel in the present invention.
Wherein, 1-oozes pipe, 2-central row ditch, 3-gutter, 4-transverse drain, 5-gutter, 6-manhole.
Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
Ooze the Tunnel Gushing in the soil stone of pipe collection Tunnel top, Tunnel Gushing runs underneath in the gutter of tunnel portal both sides along oozing pipe; Simultaneously, during rainfall, surface gathered water flows into gutter and central row ditch, the water in gutter and central row ditch is pooled in the gutter of side by transverse drain, by the gutter that side, roadside is built, the water collected by gutter introduces grit chamber, silt in Tunnel Gushing 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 the 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.
