Description
Technical field
The invention belongs to Snow dritf diaster prevention and control technical fields, are related to a kind of waveform group for having both resistance snow and leading snow function
Box-like snow wall.
Background technique
Snow dritf is a kind of weather phenomenon that multiphase flow of the snow grain of dispersion in operation near the ground has been carried under one's arms by air-flow, also known as
Snow-driving wind is commonly called as white hair wind.It is divided into low blowing, high blowing and snowstorm three classes according to the size etc. of intensity.It is a kind of
More complicated specialized fluids has biggish harmfulness.
Stop the harm of Snow dritf using gear snow fence column at present.When Snow dritf pass through gear snow fence column when, a part due to
By the barrier effect on gear snow fence column, wind energy is lost, vortex is formed before gear snow fence column, under keeping the wind speed of Snow dritf rapid
Drop weakens the energy that air-flow drives snow grain, is deposited on a large amount of Snow dritf snow grains before and after gear snow fence column, forms accumulated snow.
Accumulated snow is easily mainly formed near snow wall based on resistance snow in existing snow wall technology, reduces snow wall
Resistance avenge efficiency, and cost is relatively high.Therefore, it is necessary to cheap, environmentally friendly, snow defence is a high-efficient snow wall is researched and developed, with
Meet Snow dritf area snow defence demand.
Summary of the invention
It is simultaneous the object of the present invention is to provide a kind of waveform combined type snow wall for being suitable for Snow dritf area road domain snow defence
Care for resistance snow and lead snow two kinds of snow defence modes, improve snow defence efficiency, improve snow wall service life, and can save largely build at
Sheet and maintenance cost, meet the snow defence demand in Snow dritf area.
To achieve the above object, the technical scheme adopted by the invention is that: a kind of waveform combined type snow wall, including simultaneously

At will form a kind of structure type for leading snow, making Snow dritf that saltation and suspended occur, making near surface Snow dritf far from roadbed 4, drop
Harm of the low Snow dritf to road, guarantee driving safety.
Meanwhile the porosity for the gear snow mesh sheet installed in high vertical gear snow structure 1 is sequentially increased from the bottom to top, according to air
Principle of dynamics, when Snow dritf is by gear snow net, part Snow dritf can form one kind and lead snow form, portion as gear snow net be climbed up
Divide Snow dritf formation before and after gear snow net to be vortexed to fall near gear snow net, formation hinders snow form.In install in vertical gear snow structure 2
Gear snow mesh sheet porosity be sequentially increased from the bottom to top, when Snow dritf by gear snow net when, part Snow dritf can with gear avenge
Net, which is climbed up, to be formed one kind and leads snow form, and part Snow dritf forms vortex before and after gear snow net and falls in gear snow net nearby, forms resistance and avenges
Form.When Snow dritf is through too low vertical gear snow structure 3, part Snow dritf can be climbed up with gear snow net to be formed one kind and leads snow shape
Formula, part Snow dritf form vortex before and after gear snow net and fall near gear snow net, form resistance snow form.
Be mounted with the PE mesh sheet of three kinds of different porosities in high vertical gear snow structure 1 in gear snow monomer, in vertical gear avenge
It is mounted with the PE mesh sheet of two kinds of different porosities in structure 2, the PE net of minimum porosity is only mounted in low vertical gear snow structure 3
Piece, in this way, gear snow monomer be formed it is a kind of descend close upper dredging type hole web frame.Structure design is based primarily upon aerodynamics
Principle, when Snow dritf pass through the hole web frame when, due under it is close it is upper dredge, in gear snow monomer lower part Snow dritf some
Can by gear avenge net, another part can with gear snow net climb upwards, accelerate a part of Snow dritf cross the gear avenge monomer, one
Divide Snow dritf to form vortex to fall near gear snow monomer, forms a kind of hinder and avenge and lead the snow defence mode that snow is taken into account, improve snow defence
The service life of efficiency and gear snow net.
Snow dritf can effectively be stopped by the snow wall of the present invention that multiple groups keep off snow monomer composition, guarantee road traffic safety.
All column, drag link, transverse supporting rod and vertical supporting rods can effectively ensure that snow wall of the present invention in Snow dritf
Stability when area uses.
