Inclined inserting plate type sand blocking wall

Abstract

The invention discloses a high vertical type sand barrier device, namely an inclined inserting plate type sand blocking wall, which comprises upright posts and a plate type blocking body fixed among upright posts, wherein one ends of the upright posts are buried in ground and the other ends of the upright posts extend out of the ground; the plate type blocking body fixed among the upright posts is composed of separated inserting plates by lamination; and an air channel with an included angle of 30-60 degrees with the horizontal plane is reserved between each lamination layers of each inserting plate. The inserting plates used by the embodiment of the invention have the shape, of which the cross section is a diamond with narrow angle alpha of 30-60 degrees and the longitudinal section is a concave shape with an opening; under the arrangement conditions of the sand blocking wall, the diamond narrow angle alpha of each inserting plate points to wind direction; and under an assembling state, the concave inserting plates are inserted into fixing grooves of the upright posts so as to be fixed, and an air channel with an included angle with the horizontal plane is formed between the straight of the opening of one inserting plate and the top plane of another inserting plate contacting the inserting plate.

Description

technical field [0001] The invention relates to a high vertical sand barrier device, which belongs to the technical field of sand prevention in the engineering sand prevention field. Background technique [0002] Wind erosion and wind accumulation are the basic manifestations of wind and sand activities in arid areas. They not only form the surface morphology of desert areas, but also pose serious threats to people's production and life. For example, the sand carried by the wind reduces the visibility of the atmosphere, affects transportation, damages plants and power lines, wears down buildings and machines, blows away the organic matter on the soil surface, reduces soil nutrients, and so on. Due to global warming and intensified human activities, more and more land has become bare land, which intensifies the process of desertification in arid and semi-arid regions. Land desertification and sandstorms are a major environmental problem affecting the northern regions of my c...

Problems solved by technology

When the sand-carrying airflow passes through the sand barrier, it is forced to rise in front of the barrier, and then descends sharply after crossing the sand barrier. In this way, a strong vortex is generated before and after the sand barrier, which consumes wind energy and weakens the sand-carrying ability of the airflow. The accumulation of sand particles is formed before and after the sand barrier; but its disadvantages are: the construction is more complicated, the sand blocking effect is general, and this sand barrier is also easier to be buried

This patented product is easy to realize industrial production, but it is easier to form sand and soil accumulation behind the ventilation panel during use, and there is also a phenomenon that sand and dust will cause damage to objects behind the sand barrier after passing through the holes
