Description
Technical field
The utility model belongs to engineering dust storm（Snow）Protection technology field, is related to a kind of combined type resistance husky（Snow）Facility, it is special
It is not related to a kind of strong wound sand prevention snow protection device.
Background technology
In recent years, country is to railway, the investment steady growth of highway, and traffic base construction has welcome peak period, a plurality of new
Circuit is built to give an written reply in succession and open-minded.Due to workload greatly, it is pressed for time, line design schemes existing defects are caused, causes part
After line clear operation, sand damage, snow injury take place frequently, and drastically influence the safe operation of train.
For the invasion and attack of dust storm and wind and snow, scholars propose different prophylactico-therapeutic measures, mainly include plant measures and work
Journey measure.Biological control measure is a kind of permanent reliable dust storm and wind and snow protection mode, and shelter-forest can not only intercept the stream that passes by
And snow-driving wind, moreover it is possible to the ecological environment of zonule is improved, but it is more harsh to natural environment requirement, can only can be given birth in plant
The place application deposited, with region limitation.And anywhere engineering measure can use then without territory restriction, but when
Effect property is also shorter, it is impossible to once and for all.
The preventing and treating of early stage dust storm and wind and snow is in the wind to non-ventiation type safeguard procedures together with laying, and prevents dust storm（Snow）Before
Move.Its resistance is husky（Snow）Principle is exactly the characteristics of being redistributed using safeguard procedures surrounding flow speed, dust storm around destruction sand-protecting barrier
（Snow）The poised state of stream, makes the part grains of sand（Snow grain）It is deposited on around safeguard procedures, plays purification dust storm（Snow）The effect of stream,
So as to reach sand prevention（Snow）Purpose.But early stage, people were to dust storm（Snow）The research of stream mechanics is seldom, simply simple using gear
It is husky（Snow）Dike stops the grains of sand（Snow）Advance, do not account for influence of the safeguard procedures to air-flow, cause sand prevention（Snow）Engineering efficiency is very
It is low.With to dust storm（Snow）Flow the continuous understanding of the characteristics of motion, sand prevention（Snow）Workers are gradually recognized around safeguard procedures
, also there is reinforcement area the existing decay area of Velocity Profiles, and the velocity attenuation area in safeguard procedures altitude range can make sand（Snow）
Grain deposition, but the speed reinforcement Qu Zeke at top makes sand（Snow）Grain accelerates to jump over safeguard procedures, continues with air motion, cause by
Protection zone is husky（Snow）Evil is still more serious.To improve sand prevention（Snow）The protection efficiency of engineering, reduces construction costs, in recent years
Sand prevention（Snow）Workers are begun attempt to using ventiation type safeguard procedures, and large-area applications are in engineering practice, are achieved good
Effect, compared with non-ventiation type safeguard procedures, cost performance is increased substantially.But above-mentioned engineering leeward side is husky（Snow）Grain deposition model
Enclose still undesirable, resistance is husky（Snow）Effect of engineering is not brought into play completely, and the protection effect and construction costs of protection works are not
Matching.
Utility model content
The purpose of this utility model is to develop a kind of strong wound sand prevention snow protection device, and its leeward side grains of sand and snow grain deposit model
Enclose more suitable, can completely play the husky resistance snow effect of resistance.
To achieve the above object, the technical scheme that the utility model is used is：A kind of strong wound sand prevention snow protection device, bag
The many root posts being arranged side by side are included, protection mechanism is installed between adjacent two root posts, the protection mechanism is divided into horizontal protection machine
Structure and vertical protection mechanism, and horizontal protection mechanism and the installation of vertical protection mechanism interval；There is level side on horizontal protection mechanism
To bar shaped gap, have the gap of vertical direction on vertical protection mechanism.
The utility model sand prevention snow protection device increases leeward sidewind attenuation amplitude, make the grains of sand be easier to be deposited on it is leeward
Side；Leeward side Ruo Feng areas scope is increased, leeward side resistance is increased husky（Snow）Amount, increases substantially protection efficiency；Solve existing
Some sand prevention（Snow）Big facility leeward side is husky（Snow）The problem that grain range of deposition is not enough.The device uses modular construction, installs
Speed is fast, easy construction, can be mass.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the utility model sand prevention snow protection device, including many root posts 1 being arranged side by side, adjacent two
Protection mechanism is installed between root post 1, the protection mechanism is divided into horizontal protection mechanism and vertical protection mechanism, and laterally protection
Mechanism and vertical protection mechanism interval are installed between many root posts 1；Draw-in groove is respectively equipped with the relative side wall of 1 one groups of column,
And it is equipped with draw-in groove on the relative side wall of adjacent two root posts 1；
Vertical protection mechanism includes two crossbeams 3 be arrangeding in parallel up and down.As shown in Figure 3 and Figure 4, crossbeam 3 includes bar shaped
Beam body 5, beam body 5 is provided with multiple bayonet sockets 6；The vertical gear shown in polylith Fig. 5 and Fig. 6 is mounted side by side between two crossbeams 3
Aerofoil 4, vertical deep bead 4 includes the baffle plate 7 of tabular, and the top and bottom of baffle plate 7 are connected with fixture block 8, fixture block 8 and baffle plate 7
