specific Embodiment approach
[0021] When carrying out prevention and control in the field of sandstorm disasters in the wild, construction can be carried out in steps according to the dominant direction of sandstorm hazards along the railway and the type of underlying surface. Practice has shown that the present invention has played a promoting role in ensuring the safe operation of railways or highways and improving the local ecological environment. The specific implementation is as follows:
[0022] (A) Based on many years of observational data from mobile weather stations or local meteorological departments, analyze the dominant wind direction of sand hazards in the implementation area, combine the types of underlying surfaces in the implementation area, and determine protection based on the principle that the direction of protection measures is perpendicular to the dominant wind direction of local sand hazards Measures the direction and height of the honeycomb base 6 of the toothed inlaid tenon and tenon...

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 invention belongs to the prevention and control measures of wind-sand disasters, specifically it is a comprehensive wind-resisting and sand-resisting structure for areas with strong wind-sand activity in sandy areas, and can be applied to the prevention and control of wind-sand disasters along railways or highways. Background technique [0002] my country is one of the countries with the most severe wind-sand disasters in the world, affecting 30 provinces and municipalities across the country, seriously threatening the production and life of 400 million people, and annual direct economic losses of 54 billion yuan. The wind-blown sand disaster has become one of the main threats and major hidden dangers to our country's ecological security, constantly devouring the survival and development space of the Chinese nation. Especially in the industrial and mining areas, along transportation routes, and national defense facilities in western my cou...
