Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.
As depicted in figs. 1 and 2, on the mountain that tunnel is contiguous is broken, build many drain dykes, same drain dyke is built along the same isohypse on hillside, forms domatic flowing water for collecting rainwater on mountain; Flowing water flows in drain dyke along mountain shape.The end of all drain dykes is collected to filter, and filter builds the low-lying place near tunnel, and the water of drain dyke flows into filter along mountain shape, and filter is connected by pipeline and described sand sediment trap; Silt in domatic flowing 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.
Pressure sensor is placed in the bottom of sand sediment trap, and the output of pressure sensor connects wireless alarm; Wireless alarm is arranged on the top of sand sediment trap, and is wirelessly connected with the control centre of tunnel fire protection system.By arranging pressure sensor, the number of silt in sand sediment trap is detected, when silt is too much, control centre to tunnel fire protection system sends wireless alarm signal, the silt of prompting staff to sand sediment trap is cleared up, avoid sand sediment trap silt too much to cause blocking the pipeline of UNICOM low pool, cause low pool cannot retaining, cause tunnel fire-fighting anhydrous available.
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.
As shown in Figure 3, the cross section of drain dyke is inverted trapezoidal, and the gradient of described drain dyke upper surface is 5%, leads domatic surface pond for arranging.Drain dyke equidistantly has shrinkage joint every 10 to 15 meters, and shrinkage joint adopts asphalt jute to fill.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
