Abstract
The invention discloses a tunnel fire-fighting system with valley intermountain water being a water source. The tunnel fire-fighting system comprises a pressure sensor, a wireless alarm device, a drainage ditch, an overflow dam, a sand and gravel trap, a low-level water pool, a pump room, a high-level water pool and a tunnel fire hydrant. The overflow dam, the sand and gravel trap, the low-level water pool, the pump room, the high-level water pool and the tunnel fire hydrant are built nearby a tunnel. Through using the intermountain water as the water source, it can be ensured that stored water in a reservoir is sufficient, and the cost is lowered; the overflow dam is arranged inside the drainage ditch for storing water, so that the intermountain water is conveniently led into the sand and gravel trap. Through arranging the low-level water pool, the pump room and the high-level water pool, water pressure can be automatically provided for the fire hydrant of the tunnel. The pressure sensor is arranged for detecting the amount of sand and gravel in the sand and gravel trap. When the amount of the sand and gravel is excessively large, a wireless alarm signal is transmitted to a control center of the tunnel fire-fighting system so as to remind workers of clearing away the sand and gravel in the sand and gravel trap. In this way, it is avoided that because the amount of the sand and gravel in the sand and gravel trap is excessively large, a pipeline communicated with the low-level water pool is blocked, the low-level water pool can not store water, and no water can be provided for tunnel fire fighting.

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, and intermountain water flows along gutter, after flowing to overflow dam, blocked by the overflow dam laterally built, because the height of overflow dam is lower than gutter, after the height of overflow dam stores full water gradually, water covers from overflow dam, continues to trickle along gutter.The retaining of overflow dam flows to sand sediment trap by bleed off pipe, 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 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, pressure on pressure sensor reaches the upper limit, and sends signal to wireless alarm, and wireless alarm sends wireless alarm signal to the control centre of tunnel fire protection system, 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 preventing the stone in intermountain water and branch leaf etc. from flowing into overflow dam, causing overflow dam water retention capacity to reduce or blocking bleed off pipe, the grid being used for filtrating impurity in water is set in the gutter of the inflow direction in overflow dam front.
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.
