Abstract
The invention discloses a self-lifting sand board, which includes a sandy wind baffle and a base, wherein the front end of the base is connected with the sandy wind baffle; the rear end of the base is hinged with a vertical rod fixed on a foundation; and a flexible rope is connected between the vertical rod and the base. As the front end of the base is not in permanent connection with the ground and the rear end of the base is hinged with the vertical rod, in case of sandy wind, the sandy wind baffle is lifted, a clearance is reserved under the base, and windy sand partially deposits in the clearance, so that the sandy wind baffle is lifted gradually, and is prevented from being buried by the windy sand; meanwhile, the base is connected with the vertical rod fixed on the foundation, so as to be prevented from being blown away by heavy sandy wind; besides, the base is connected with the vertical rod through the flexible rope with proper length guaranteeing the lifting space of the sandy wind baffle and preventing the sandy wind baffle from being blown down by the sandy wind.
Description
Technical field
The present invention relates to a kind of sandboard, be specifically related to a kind of from raising the formula sandboard.
Background technology
NORTHWEST CHINA section 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 is prevented and treated 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 that affects these domain engineering construction qualities, restricted to a certain extent the development that Economy of Western Areas is built.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 wall, PE net height vertical sand barrier, reed sand fence etc., certain effect has been played in these sand-prevention engineering measures in the sandstorm prevention and cure projects such as existing railway, highway, but the problem such as the ubiquity difficulty of construction is large, cost is high, the sand prevention benefit is low.
Application number is that 201210235262.7 Chinese patents disclose a kind of " the three-dimensional sand fence of pin-connected panel ", it comprises many group combination fence, should form screen one by many group combination fence, every group is made up fence by the sand monomer composition of three stepped settings, and the distance that two adjacent groups makes up between the sand monomer corresponding in the fence is 0.5～1m.This sand rail shape becomes three-dimensional sand fence, and effectively reducing wind speed disturbs sand-flow field, realizes stopping dust storm.But the problem of the at present common existence of this class sand fence is to be buried by dust storm easily.
Summary of the invention
The present invention is not enough in order to solve in the prior art, provides a kind of from raising the formula sandboard.
For achieving the above object, the present invention adopts following technical proposals:
A kind of it comprises dust storm baffle plate and base from raising the formula sandboard, and the front end of described base is connected with the dust storm baffle plate, and the rear end is hinged with the montant that is fixed on the ground, also is connected with flexible strand between montant and the base.
The high 2-4 rice of described dust storm baffle plate, the long 0.5-3 rice of described base.
Described flexible strand is chain or nylon rope.
Because the front end of base is not fixedly connected with ground, rear end and montant are hinged, therefore when dust storm blows, the dust storm baffle plate is raised, make base below leave the space, the part dust storm is deposited in this space, this dust storm baffle plate is elevated gradually, can avoids being buried by dust storm.Simultaneously, because base is connected with montant on being fixed on ground, in the time of can avoiding dust storm excessive it is blown away.In addition, because base is connected by flexible strand with montant, the existing space of raising of length assurance dust storm baffle plate of flexible strand can not blown by dust storm again and be turned over.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention uses view.
Wherein, 1. dust storm baffle plate, 2. base, 3. ground, 4. montant, 5. chain.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of from raising the formula 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, the rear end is hinged with the montant 4 that is fixed on the ground, also be connected with chain 5 between montant 4 and the base 2, the two ends of chain 5 all are connected to the middle part of montant 4 and base 2.
Described dust storm baffle plate 1 is high 2 meters, described base 2 long 2 meters, wide 2 meters.
Adopt baffle plate of the present invention to be arranged into the sand fence, as shown in Figure 2, when dust storm was larger, chain 5 can prevent effectively that dust storm baffle plate 1 from being turned over by wind.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be 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 modifications that creative work can make or distortion still in protection scope of the present invention.
Claims (3)
1. one kind from the formula sandboard that raises, and it comprises dust storm baffle plate and base, it is characterized in that, the front end of described base is connected with the dust storm baffle plate, and rear end and the montant that is fixed on the ground are hinged, also are connected with flexible strand between montant and the base.
2. as claimed in claim 1 from raising the formula sandboard, it is characterized in that the high 2-4 rice of described dust storm baffle plate, the long 0.5-3 rice of described base.
3. as claimed in claim 1 from raising the formula sandboard, it is characterized in that described flexible strand is chain or nylon rope.
