Abstract
The invention discloses a self-elevation type sand blocking plate. The self-elevation type sand blocking plate comprises a sand and a base and is characterized in that the front end of the base is connected with the sand baffle, and the rear end of the base is hinged to a vertical rod fixed to a foundation; the distance between the hinge point of the base and the vertical rod and the ground is larger than 0 meter; and a chain is further connected between the vertical rod and the base; and multiple self-elevation type sand blocking plate are arranged to form a sand blocking fence. The self-elevation type sand blocking plate has the beneficial effects that the sand blocking plate can form a stable triangular structure towards sandy wind so as to share wind impact; and a space which is below the base and large enough for accommodating sand is ensured. Due to a fact that sand can be easily deposited at the hinge position, the space is big enough so as to avoid the phenomenon that a large amount of the sand is accumulated at the position close to the hinge position easily and consequently the sand baffle is quickly elevated; and meanwhile, a certain distance exists between the hinge position and the ground, and therefore the sand baffle has enough elevation space.
Description
Technical field
The present invention relates to a kind of sandboard, be specifically related to a kind of from elevated sandboard.
Background technology
NORTHWEST CHINA portion local climate arid; rainfall is rare; wind-sand activity is frequent; in recent years; along with the propelling of China's development of the West Regions, the infrastructure construction develop rapidly of the Northwest, but sandstorm prevents and treats the engineering construction that a difficult problem still perplexs the fields such as railway, highway, ancient site protection and urban construction; become the major issue affecting these domain engineering construction qualities, constrain the development that Economy of Western Areas is built to a certain extent.Machinery sand fence is a kind of sand-prevention engineering measure, it is the important technical of control railway or highway sand damage, common sand-prevention engineering measure has concrete sleeper sand stop wall, PE net height vertical sand barrier, reed sand fence etc., these sand-prevention engineering measures serve certain effect in the sandstorm such as existing railway, highway prevention and cure project, but the problem such as ubiquity difficulty of construction is large, cost is high, sand prevention benefit is low.
Application number is that 201210235262.7 Chinese patents disclose one " the three-dimensional sand fence of pin-connected panel ", it comprises many group combination fence, these many groups combination fence form one screen, often group combination fence forms by the sand monomer of three stepped settings, and the distance between sand monomer corresponding in two adjacent groups combination fence is 0.5 ~ 1m.This sand rail shape becomes three-dimensional sand fence, effectively can reduce wind speed, and interference sand-flow field, realizes the stop to dust storm.But the common Problems existing of current this kind of sand fence is easily buried by dust storm.
Summary of the invention
The present invention is not enough in order to solve in prior art, provides a kind of from elevated sandboard.
For achieving the above object, the present invention adopts following technical proposals: a kind of from elevated sandboard, it comprises dust storm baffle plate and base, it is characterized in that: the front end of described base is connected with dust storm baffle plate, rear end is hinged with the montant be fixed on ground, and described base and montant pin joint are overhead greater than 0 meter; Also chain is connected with between montant and base; Each baffle plate is arranged into sand fence.
As claimed in claim 1 from elevated sandboard, it is characterized in that, described base and montant pin joint are overhead 0.5-1 rice.
As claimed in claim 1 from elevated sandboard, it is characterized in that, described dust storm baffle plate height 2-4 rice, the long 0.5-3 rice of described base.
Because the front end of base is not fixedly connected with ground, rear end and montant hinged, therefore when dust storm blows, dust storm baffle plate is raised, and makes to leave space below base, and part wind-sand area is in this space, this dust storm baffle plate is elevated gradually, can avoids being buried by dust storm.Meanwhile, because base is connected with the montant be fixed on ground, blown away when dust storm can be avoided excessive.In addition, because base is connected by flexible strand with montant, the length of flexible strand ensures that the existing space of raising of dust storm baffle plate can not be blown by dust storm again and turns over.
There is certain distance in base and montant pin joint and ground, its effect is:
(1) namely can form leg-of-mutton rock-steady structure in the face of dust storm, share wind-force;
(2) can protect again the space being large enough to hold dust storm below base, because hinged place easily deposits dust storm, therefore this space can prevent from enough greatly piling up a large amount of dust storm easily near hinged place and dust storm baffle plate being elevated very soon; (3) simultaneously, hinged place distance ground certain distance, can make again dust storm baffle plate enough raise space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is using state schematic diagram of the present invention.
Wherein, 1. dust storm baffle plate, 2. base, 3. ground, 4. montant, 5. chain.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, a kind of from elevated sandboard, it comprises dust storm baffle plate 1 and base 2, the front end of described base 2 is connected with dust storm baffle plate 1, rear end is hinged with the montant 4 be fixed on ground, also be connected with chain 5 between montant 4 and base 2, the two ends of chain 5 are all connected to the middle part of montant 4 and base 2.
Described base 2 and montant 4 pin joint overhead 3 have 0.5 meter.
Described dust storm baffle plate 1 is high 2 meters, long 2 meters of described base 2, wide 2 meters.
Adopt baffle plate of the present invention to be arranged into sand fence, as shown in Figure 2, when dust storm is larger, chain 5 can be effectively anti-
Only dust storm baffle plate 1 is turned over by wind.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
Claims (3)
1. from an elevated sandboard, it comprises dust storm baffle plate and base, it is characterized in that: the front end of described base is connected with dust storm baffle plate, and rear end is hinged with the montant be fixed on ground, and described base and montant pin joint are overhead greater than 0 meter; Also chain is connected with between montant and base; Each baffle plate is arranged into sand fence.
2. as claimed in claim 1 from elevated sandboard, it is characterized in that, described base and montant pin joint are overhead 0.5-1 rice.
