Description

Water supply device for tunnel
Technical field
The present invention relates to a kind of water supply installation, particularly a kind of water supply device for tunnel that is used for constructing tunnel.
Background technology
Highway, the on-the-spot traditional approach that supplies water of railway tunnel construction supply water for head-tank pressure reduction, pump group power and reservoir size and height design with discharge and the required outflow head of least favorable water distribution point by maximum and limited by geographical conditions, reservoir is disposable input, can not reuse, the section of going down the hill is for additionally laying on the pipeline, and easily causes the massif vegetation deterioration; Because of satisfying H-Max and traffic requirement, the water pumper power setting is the low load with strong power general layout, and energy waste is serious.In the water-deficient area and high and cold mountain area, then will water tank fortune water be installed, or classification is drawn water and is longly supplied water apart from pipeline with automobile, head-tank is easy to freezing, and the easy bursting by freezing of water pipe must be equipped with that the special messenger is daily to keep an eye on maintenance in turn, not only building time is long, cost is high, and restricts the progress of constructing in earlier stage in the tunnel.Existing way of supplying water mainly has the following disadvantages:
1, because of the landslide, peel off, loose, the mountain top discrepancy in elevation does not reach and requires and the high mountain gorge location, and the high mountain pond can't be built in the mountain top.
2, reservoir is disposable input, can not reuse, and the section of going down the hill and easily causes the massif vegetation deterioration, the cost height for additionally laying on the push pipe road, hole to hole.
3, the landform position pipeline that alters a great deal must adopt exposed installation, and need wrap up heat insulating material winter, perhaps buries underground undergroundly, and the unsettled place of tube coupling need establish supporting-point in case sagging destruction of pipeline section header and leakage, causes rock mass to cave in or influences construction water.
4, pipeline is longer outside the hole, and hydraulic pressure, water loss are too much, and pump-room is established the special messenger and is responsible for the machinery maintenance maintenance, if personnel lack a sense of responsibility, can often cause the shut-down of cutting off the water in the hole.
5, the construction and installation time long, delay the early stage construction speed.
6, equipment and installation, maintenance maintenance cost expense height use extremely uneconomical.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, a kind of water supply device for tunnel is provided.The present invention only needs the water source directly is evacuated to the water tank that is arranged on tunnel portal, directly replaces high mountain pond water supply installation, reduces the outer pipeline length in hole, and the saving cost is also reusable, and the present invention simple in structure, easy to use, be convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: water supply device for tunnel, it is characterized in that: comprise water tank that is arranged on tunnel portal and the water tank that is arranged on water tank one side, described water tank is connected with water pumper in being installed in water tank by the pipeline that stretches out from the water tank top, described pipeline is provided with water intaking valve, be connected with the air compressor trunk line on the described pipeline, described air compressor trunk line is provided with admission valve, and an end of described air compressor trunk line is connected with air compressor, and the bottom of described water tank is provided with water pipe.
Above-mentioned water supply device for tunnel, the top of described water tank is provided with extract duct, and described extract duct is provided with outlet valve.
Above-mentioned water supply device for tunnel, on the described pipeline and the top that is positioned at admission valve is provided with stop valve.
Above-mentioned water supply device for tunnel, described water pipe is provided with one way valve.
Above-mentioned water supply device for tunnel, described water tank are provided with fluviograph and are positioned at the pressure meter of fluviograph top.
The present invention compared with prior art has the following advantages: use water supply device for tunnel of the present invention can guarantee the stability of construction water, reduce the operator on duty, saved the labour, and used this water supply device for tunnel to shorten the installation of pipeline, this water tank can be reused, saved fund, conserver power source 40%-60% can produce good economic benefit, the configuration simple and flexible of this water supply device for tunnel, easy for installation, good stability can promote the construction speed that goes into operation early stage.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
