Wind-proofing sand-blocking device

Abstract

The invention discloses a wind-proofing sand-blocking device for preventing sand from affecting or damaging railways and other facilities. The wind-proofing sand-blocking device comprises a vertical column buried on the ground and a wind-blocking ball provided with through holes, wherein an anti-corrosion steel wire mesh is fixed on the vertical column, and the wind-blocking wall is fixed on the iron wire mesh. The wind-blocking wall comprises a plurality of wind-blocking monomers which are combined together; each wind-blocking monomer is a rectangular double-sided sandwich structure consisting of a windward side and leeward side, wherein the thickness of a hollow sandwich layer is 5 to 15cm; the windward side and leeward side of the wind-blocking monomer are respectively and symmetrically provided with at least one through hole; and holes on the windward side of the monomer and holes on the leeward side thereof are not on the same axis, the ration of the diameter of the holes of the windward side to that of the holes of the leeward side is 8:1 to 1:1, and the windward side and the leeward side are separated by a strut.

Description

technical field [0001] The invention relates to a high vertical sand barrier structure, in particular to a wind and sand retaining wall for protecting facilities such as railways from being affected or damaged by wind and sand, and belongs to the technical measures of sand prevention in the field of engineering sand prevention. The invention consists of a column buried on the ground and a windshield wall provided with through holes. Background technique [0002] Wind erosion is the basic manifestation of wind and sand activity in desert areas. It not only forms the surface morphology of desert areas, but also poses a serious threat 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 wires, wears out buildings and machines, blows away organic matter on the soil surface, and reduces soil nutrients. Due to global warming and intensified human activities, more and more la...

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

Although this patent can play a role of wind and sand prevention to a certain extent, it cannot prevent the gravel from burying the railway.
