Sand barrier structure and assembly thereof

Abstract

The invention relates to the technical field of sand prevention engineering, and discloses a sand barrier structure and an assembly thereof. The sand barrier structure comprises a base, an annular slide rail and a protection body, wherein the base is fixed in sandy soil, the annular slide rail is arranged at the upper end of the base, the protection body is vertically arranged, and the lower end of the protection body is slidably connected to the annular slide rail. According to the sand barrier structure and the assembly thereof, the base is deeply buried in sandy soil, the protection body is exposed out of the surface of the sandy soil, when strong wind blows over, wind power drives the protection body to rotate around the annular slide rail, therefore power applied to the sandy soil by the strong wind is transferred into rotating force of the protection body, the rotating force is consumed through rotation of the protection body, on one hand, fixing of flowing sandy soil is guaranteed, on the other hand, it is conveniently avoided that the sand barrier structure is blown down or deflected by wind and even generates rigid fracture, and meanwhile due to the fact that the slide rail is arranged to be annular, it can be guaranteed that kinetic energy is consumed by rotating energy no matter which direction the wind blows.

Description

technical field [0001] The invention relates to the technical field of sand control engineering, in particular to a sand barrier structure and components thereof. Background technique [0002] The world's land area is 162 million square kilometers, accounting for 30.3% of the total earth area, of which about 1 / 3 (48 million square kilometers) is arid and semi-arid desert areas, and it expands at a rate of 60,000 square kilometers every year However, the desert area has accounted for 20% of the total land area, and 43% of the land is facing the threat of desertification. Sand prevention and sand fixation projects are becoming more and more important. [0003] Sand barriers are an important measure for sand prevention and sand fixation projects. Sand barriers, also known as mechanical sand barriers and wind barriers, are barriers made of firewood, straw, clay, branches, slats, pebbles and other materials on the sand surface. , is an effective engineering sand fixation measure...

AI Technical Summary

Problems solved by technology

[0004] Most of the sand barrier structures in the related art are rigid structures, which are used to fix the sand surface. However, in the desert, there are often strong winds. When the wind is strong, the rigid structure of the sand barrier structure is easily damaged. The wind blows down or deflects or even produces a rigid fracture, so that the sand cannot be fixed and the sand barrier structure fails
