Abstract

The invention discloses a kind of high vertical sand barriers, including several connected sand prevention units, each sand prevention unit includes two pieces of sandboards and a sand net, the sandboard and the sand net are vertically arranged, in the same sand prevention unit, two pieces of sandboards are located at sand net both sides, and two pieces of sandboards are located at described sand net wire side the same side, are obliquely installed relative to the sand net and extended respectively to sand net both sides.The scale sand dune that the present invention passes through formation(Or sand dune group)The movement of the grains of sand is hindered, it is simple in structure, easy for installation, durable to achieve the purpose that defend and control sand, and there is good protection benefit.

Description

A kind of high vertical sand barrier
Technical field
The present invention relates to engineering sand control equipment manufacturing technology field, especially a kind of high vertical sand barrier.
Background technology
Desertification is the environmental problem with some areas with the most serious of global range effect that the world today is faced One of, have become the outstanding problem for jeopardizing National Ecological Security.In desertification of land and the process of desert spread movement, companion With the multiple dimensioned movement of sandy environment, including short distance wind-sand flow, and the conveying of long range is our common sand Dust storm.Sandstorm is the common a kind of disastrous natural weather phenomenon of desert and arid area, has larger destructiveness and danger Production and living of natural environment and the mankind etc. can be caused serious influence by evil property.
The major measure of Desertification Control is sand-prevention engineering.Sand-prevention engineering refers to being prevented and control sandy storm harm using mechanical means Technical system, the core of prevention are that the wind speed of near surface formation is reduced using technical measures, reduce the sedimentary loading in air-flow, delay With the Forward for preventing sand dune, to achieve the purpose that weaken and avoid hazards of sand storms.
Invention content
In view of the deficiencies of the prior art, the present invention proposes a kind of high vertical sand barriers, pass through the scale sand dune of formation(Or it is husky Cumulus)The movement of the grains of sand is hindered, it is simple in structure, easy for installation, durable to achieve the purpose that defend and control sand, and have Good protection benefit.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical scheme:
A kind of high vertical sand barrier, including several connected sand prevention units, each sand prevention unit include two pieces of sandboards With a sand net, the sandboard and the sand net are vertically arranged,
In the same sand prevention unit, two pieces of sandboards are located at sand net both sides, two pieces of sandboard positions In described sand net wire side the same side, it is obliquely installed relative to the sand net and extends respectively to sand net both sides.
Further, in the same sand prevention unit, side that the opening between two pieces of sandboards is blown towards dust storm To.
Further, each sand prevention unit is along arranged in a straight line, opening between two pieces of sandboards of each sand prevention unit Mouth both faces towards same direction, is connected by sandboard between the two neighboring sand prevention unit.
Further, each sandboard is identical with each sand net vertical height.
Further, each sandboard is identical with the horizontal direction length of each sand net.
A kind of high vertical sand barrier of the present invention, passes through the scale sand dune of formation(Or sand dune group)The movement for hindering the grains of sand, from And achieve the purpose that defend and control sand, it is simple in structure, easy for installation, durable, and there is good protection benefit.
Description of the drawings
Fig. 1 is a kind of stereoscopic schematic diagram of high vertical sand barrier of the present invention.
Specific implementation mode
Present invention will now be described in detail with reference to the accompanying drawings., and the description of this part is only exemplary and explanatory, is not answered There is any restriction effect to protection scope of the present invention.
A kind of high vertical sand barrier as shown in Figure 1, including several connected sand prevention units, each sand prevention unit include two pieces Sandboard 1 and a sand net 2, sandboard 1 and sand net 2 are vertically arranged,
In same sand prevention unit, two pieces of sandboards 1 are located at 2 both sides of sand net, and two pieces of sandboards 1 are located at 2 wire side of sand net The same side is obliquely installed relative to sand net 2 and extends respectively to 2 both sides of sand net.Two sandboards 1 are opposite with sand net 2 It is symmetrical arranged, and the angle between two sandboards 1 is 60 degree.
In same sand prevention unit, direction that the opening between two pieces of sandboards 1 is blown towards dust storm.
For each sand prevention unit along arranged in a straight line, the opening between two pieces of sandboards 1 of each sand prevention unit both faces towards same direction, It is connected by sandboard 1 between two neighboring sand prevention unit.
Each sandboard 1 is identical with each 2 vertical height of sand net, is set as 2m in the present invention.
Each sandboard 1 is identical with the horizontal direction length of each sand net 2.
The nylon sand-proof net for the advantages that sand net 2 is using anticorrosive, anti-aging, easy construction.Sandboard 1 selects excellent as possible Matter, light and convenient for moulding light sheet material.The connection of sandboard 1 and sand net 2 may be used embedding according to the selection of sandboard 1 Enter, completed by modes such as his object rivetings.
When the high vertical that stream is combined by the sandboard 1 with sand net 2 is when husky unit, sandboard 1 forces dust storm Stream changed course makes it advance along the direction that sandboard 1 is guided, and since dust storm can only be from sand net 2, so ventilative sectional area Reduce half so that correspondingly increase across the silt discharge of sand net 2 and be twice, the grains of sand are accumulated after sand net 2, and it is husky to form scale Mound 3(Or sand dune group).When 3 height of sand dune is higher, movement speed is more slow, to achieve the purpose that defend and control sand. By hindering a kind of husky sand-protecting barrier of method design being combined with the two kinds of sand control means that alter course.It, can further to slow down the movement on sand dune After completing mechanical sand control work, implement vegetative sand control, by planting psammophytes, is fixed the sand using root system of plant, realize mark Originally simultaneous to control.
A kind of high vertical sand barrier of the present invention, passes through the scale sand dune of formation(Or sand dune group)The movement for hindering the grains of sand, from And achieve the purpose that defend and control sand, it is simple in structure, easy for installation, durable, and there is good protection benefit.
