A superimposed multi-layer windproof and sand-blocking comprehensive structure

Abstract

The invention relates to a stacked type multi-layer wind prevention and sand resistance comprehensive structural body. The structural body is structurally characterized in that slice layer sand filtration and ventilation type grids are arranged between two butt joint stand columns, the lower portions of the stand columns are connected with bearings of slide wheels in a butt joint mode, sand prevention type rail grooves are formed by welding porous type sand leaking slide plates, sand discharge holes and square rails, the sand prevention type rail grooves are located on a tooth-shaped embedment mortise and tenon cellular base, the slice layer sand filtration and ventilation type grids are connected through stacked lock catches, and automatic telescopic regulating valves are located in the middles of stacked lock catch crossed supports. By means of the stacked type multi-layer wind prevention and sand resistance comprehensive structural body, a traditional two-dimensional fixed vertical sand prevention fence is improved into a fence of a push-pull stacked three-dimensional structure, a solid base is changed into a base of a cellular ventilation structure, it is avoided that airflow streams nearby the stand columns, and near-surface transited wind-drift sand can be effectively intercepted. By means of the telescopic regulating valves, the interval of the slice layer sand filtration and ventilation type grids and the relative positions of fence vent holes can be automatically regulated, the overall porosity degree of the comprehensive structural body can be improved, and railway sand storm protection measure benefits are maximized.

Description

technical field [0001] The patent of the present invention belongs to the prevention and control measures of wind and sand disasters, specifically, it is a comprehensive wind and sand blocking structure adopted for areas with strong wind and sand activities in sandy areas, which can be applied to the prevention and control of wind and sand disasters along railways or highways. Background technique [0002] my country is one of the countries with the most serious wind and sand disasters in the world, affecting 30 provinces and municipalities across the country, seriously threatening the production and life of 400 million people, and causing an annual direct economic loss of 54 billion yuan. Wind and sand disasters have become one of the main threats and major hidden dangers to my country's ecological security, constantly engulfing the survival and development space of the Chinese nation. Especially in industrial and mining areas, along traffic lines, and national defense faci...

Problems solved by technology

Especially in industrial and mining areas, along traffic lines, and national defense facilities in western my country, due to severe wind and sand disasters and fragile ecological environments, coupled with the limitations of local water, light, soil fertility and other ecological factors, it is difficult to implement plant sand control measures.
