Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
Based on a tunnel fire protection system for elevated storage case, comprise water source, sand sediment trap, low pool, pump house, elevated storage case, water tank base and tunnel fire plug;
Described sand sediment trap and water source UNICOM, 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 elevated storage case by described pump house; Described elevated storage case is fixed on water tank base; Described elevated storage case is connected in described tunnel fire plug by least two pipelines; The height of described elevated storage case is arranged according to the hydraulic pressure of tunnel fire plug.
Build the problem of head-tank difficulty for solving the strategically located and difficult of access mountain area of physical features, the present invention's elevated storage case replaces head-tank.Prior processing stainless steel water storage box, is arranged on eminence by water tank by water tank base.Water tank base comprises levels up plate and bracing frame, described in level up plate and comprise four pieces of identical triangle scabs; Described triangle scab is isosceles right triangle; The center of each triangle scab is provided with cement spout hole; The right-angle side docking of four pieces of identical triangle scabs is fixed into a square plate for leveling up plate; Support frame as described above is rectangle support body, its inner fenestral fabric be welded by support bar that distributes, and described fenestral fabric is more than one deck; Support frame as described above is fixed by screws in hole that ground is dug out in advance, and level up plate and be fixed on bracing frame, described elevated storage case is fixed on to be leveled up on plate, and the position that described water tank base is built is higher than described low pool.
Four pieces of identical triangle scab splicing fixed forms are turning locator card and bolt, and three angles place of each triangle scab is provided with turning standing block hole, and three limits are provided with radius bolt hole; Turning standing block hole is for installing turning locator card, and radius bolt hole is used for erection bolt; The shape of described radius bolt hole is horse-hof shape or circle.
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 elevated storage case again, because the position of elevated storage case is higher than the position of tunnel fire plug, the automatic mineralization pressure of the water in fire plug.The height of elevated storage case 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 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, the capacity of described low pool and elevated storage case is suitable, after the water of elevated storage case is used up, low pool can to the moisturizing of elevated storage case once, and what can ensure to provide two elevated storage case 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 elevated storage case 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 elevated storage case can flow in water inlet pipe automatically, the water inlet pipe be connected between elevated storage case with tunnel fire plug arranges horn mouth down in elevated storage case one end, and described horn mouth is lower than the lowest water level at least 0.5 meter of elevated storage case.Horn mouth and the clear distance at the bottom of elevated storage case pond are more than or equal to 0.8 times of water inlet pipe caliber, and the clear distance of described flared rim and elevated storage case 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 elevated storage case with tunnel fire plug.
Water inlet pipe should take anti-corrosion measure, the water inlet pipe be connected between elevated storage case 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.
