Description
Technical field
The invention belongs to environment protection fields.It is mainly used for freight rail tunnel face periphery dust pollution improvement, and in particular to one
Kind tunnel face Piston Action Wind Dust Improvement equipment.
Background technique
As the train moves into the tunnel, air is compressed in front of train, and pressure sharply increases, and generates compressed air stream;Work as column
When the tailstock of vehicle enters tunnel, air has little time to supplement in tunnel, and pressure drastically reduces, and forms expansion (suction) air-flow;
Form Piston Action Wind.Compressed air stream, expanded gas flow, turbulent flow are iteratively operating on train in tunnel, blow the coal surface in compartment
It rises, causes fugitive dust in tunnel, pressure strongly reduces when carrying the Piston Action Wind arrival tunnel exit of a large amount of dirt, and gas volume is quick
Expansion, it is fan-shaped to be spread to periphery rapidly, and train tail goes out the swabbing effect generated when tunnel face, and the dust-laden in tunnel is empty
Gas is largely taken out of, and large-scale dust pollution is caused.
The dust pollution problem generated in the loose cargo transports such as Railway Coal, ore has caused the height of environmental protection administration
Concern, the especially bulk shippings train such as coal, ore is when passing through tunnel, by Leads to new breeze tunnel, the Piston Action Wind wind of generation
Speed is larger and causes the fugitive dust of loose unpacked material serious with vortex, and train goes out the swabbing effect generated when tunnel face, will be in tunnel
Dust laden air take tunnel out of, being diffused into surrounding enviroment, cause very serious dust pollution, therefore solve coal, ore etc. dissipates
Surrounding enviroment dust pollution caused by when goods transport train passes through tunnel, has become current urgent problem to be solved.It is existing
Freight rail tunnel face periphery is not processed this, cannot solve the above problems.
Summary of the invention
The present invention provides a kind of tunnel face Piston Action Wind dust pollution abatement equipments, it is therefore intended that can effectively solve coal
When the bulk shippings train such as charcoal, ore passes through tunnel, the problem that the Piston Action Wind of generation causes the dust pollution of loose unpacked material serious,
Cost is low with running cost, can also save a large amount of costs of labor.
The present invention is implemented with the following technical solutions:
A kind of tunnel face Piston Action Wind dust pollution controlling device, controlling device setting is in track two sides and from tunnel face to tunnel
Outer extension, the controlling device are made of concrete foundation, main supporting structure, suppression stratification of wind, dust-break layer;Main supporting structure setting exists
Suppression stratification of wind, dust-break layer are installed, dust-break layer is located at the inside of main supporting structure, presses down above concrete foundation, on main supporting structure
Stratification of wind is located at the outside of main supporting structure.
Outer layer dust-break layer is installed to thin segmentation from bottom to top and along direction of traffic by close on the outside of main supporting structure, internal layer
Press down stratification of wind on the inside of main supporting structure from bottom to top and along direction of traffic by it is close to dredge segmentation installation, realization air pressure, air-flow by
Small gradient decaying is arrived greatly, is changed into Piston Action Wind in buffer area consistent with ambient wind.
Reinforced concrete foundation according to the span of main supporting structure, height, stress condition and design, material use C35 steel
Reinforced concrete is integrally formed foundation bolt with basis, main supporting structure passes through column by embedding anchor bolts when casting concrete
Sole is connect with foundation bolt.
Main supporting structure uses rod piece grid structure, and grid structure uses just putting quadrangular pyramid structure.Rod member for grid mutually it
Intermediate node uses bolted spherical node, and rod member for grid uses ratio-frequency welded tube or seamless pipe, and bolt uses No. 45 steel.Space can also be used

The ventilation unit of anti-fugitive dust is using a kind of resistance dirt ventilator disclosed in China Patent No. ZL201820326434.4.
The working principle of the invention: establishing a buffer area at tunnel face, is acted on using the control wind of lower layer's suppression stratification of wind, control
Train Piston Action Wind processed air pressure at tunnel exit cannot strongly reduce, and return to a part of Piston Action Wind, and taking dirt air cannot
Enough diffusions rapidly will take the control of dirt air inside equipment, and the suppression wind for recycling lower layer's suppression stratification of wind Windbreak barrier strip mutual is made
With by mutual collision, the rubbing action of air-flow, consuming its kinetic energy, reduce it and take dirt ability, recycle the anti-of upper layer dust-break layer
The wind deflector inclined-plane of the ventilation unit of fugitive dust is to the collecting action of air-flow, so that the semiclosed sky that the ventilation unit of anti-fugitive dust surrounds
Interior pressure becomes larger, to prevent internal diffussion of dust to outside.
The buffer area dust-break layer, press down stratification of wind setting be arranged from the near to the distant by close to thin gradual change in tunnel face so that
Piston Action Wind makes it gradually tend to be steady, combines together with atmosphere, drop buffer area is broken, consumption declines low-flow pressure
Low gas takes dirt ability, reaches depositing dust purpose.
When the present invention can effectively solve the bulk shippings train such as coal, ore and pass through tunnel, the Piston Action Wind of generation causes
The serious problem of the dust pollution of loose unpacked material, and cost is low with running cost, can also save a large amount of costs of labor.
