Abstract

The invention relates to a sand wind speed reducing plate, a sand-preventing barrier, a manufacturing method of the sand wind speed reducing plate and application of the sand wind speed reducing plate and the sand-preventing barrier. The sand wind speed reducing plate comprises high density polyethylene, uvioresistant additives and optional coloring agents, wherein the thickness of the sand wind speed reducing plate ranges from 1mm to 4mm, and flow guide holes are distributed in the sand wind speed reducing plate. The manufacturing method of the sand wind speed reducing plate comprises the steps of (1) burdening, (2) drying and mixing of raw materials, (3) extrusion, (4) press polishing, (5) punching, (6) drying and (7) detection. According to the invention, the sand wind speed reducing plates are fixedly arranged between stand columns and press plates through bolts, and the stand columns are fixedly arranged in desert soil, so that the wind-speed-reducing sand-preventing barrier which can continuously extend is formed. The sand wind speed reducing plate and the sand-preventing barrier are applied to highways, railways, municipal services and sand stabilization and afforestation engineering in the regions such as desert, gobi desert and oasis edges.

Description

technical field [0001] The invention relates to the field of wind and sand control, in particular to a wind and sand deceleration plate, a sand prevention barrier and a manufacturing method thereof, and the application of the wind and sand deceleration plate in the field of wind and sand control. technical background [0002] my country is one of the countries most seriously endangered by desertification in the world. The Fourth National Desertification and Sandification Monitoring Bulletin shows that by the end of 2009, my country's desertified land area has reached 2,623,700 km 2 , the desertification area is 1.7311 million km 2 , accounting for 18.03% of the country's land area. Inner Mongolia, Xinjiang, Qinghai, Gansu and other places still have a land area of ​​310,000 km with obvious desertification tendency 2 . In the northern part of my country, due to the reduction of precipitation, the decrease of groundwater level, the degradation of natural grassland and the ...
