Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
As depicted in figs. 1 and 2, built in gutter in the side of highway away from tunnel fire plug, longitudinally row's infiltration ditch is built on the isolation strip in the middle of two direction runways, is built by gutter in the side of highway near tunnel fire plug.Gutter and longitudinal direction arrange the ditch that seeps water, longitudinal row is seeped water between ditch and gutter by transverse drain UNICOM; Then gutter and longitudinal row's infiltration ditch all flow to gutter by transverse drain, and gutter passes through again the water inlet UNICOM of road surface chute and filter.Be arranged on water burst pipeline UNICOM in tunnel structure body to gutter and gutter, then the water burst on Tunnel top flows in gutter, also as a part of water source.Filter builds the low-lying place near tunnel, and the water of drain dyke flows into filter along mountain shape, and after filter collects water burst and road surface water, filter is connected by pipeline and described sand sediment trap; Silt in 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 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.
Due to water water source, road surface is likely polluted by greasy dirt or acidic materials, if the water source of pollution is delivered to fire plug can cause corrosion to itself and pipeline, therefore, water quality sensor is set in low pool, the degree of contamination of water quality is detected.Meanwhile, build the sewage reservoir that position is lower, in low pool, arrange switching mechanism near low pool, this switching mechanism comprises water inlet and two delivery ports, two delivery ports through low pool pool wall respectively with pump house UNICOM and sewage reservoir UNICOM; Described switching mechanism is connected with described water quality sensor, receives the whether contaminated signal of water quality.When water source is contaminated, switching mechanism by water inlet pipe conducting to sewage reservoir, by effluent discharge to sewage reservoir.When water quality is normal, water is passed through pump house pump to head-tank, for fire-fighting.
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.
