Problems solved by technology
The polyester material has the above-mentioned characteristics. It has been developed unprecedentedly because of its convenient production and wide application range. It mainly exists in the form of mesh cloth. In industrial production, polyester mesh is widely used in metallurgy, pharmaceuticals, In many fields such as chemical industry and papermaking, polyester mesh is discarded as waste once it is damaged, deformed and other damages. In our country, a large amount of waste polyester mesh is discarded every year. At present, there is no better one. Measures to deal with waste polyester mesh, resulting in a large amount of waste polyester mesh being discarded into the environment, polluting the environment

The invention relates to a sand barrier manufactured by utilizing a waste polyester net and a manufacturing and implementing method thereof. The sand barrier comprises a net band and a support rod for supporting the net band; the net band made of the waste polyester net is in a long band shape, and the support rod is in a long strip shape and is provided with fixing slots axially distributed along the support rod at the middle lower part; the fixing slots divide the middle lower part of the support rod into two limbs of which the insides are respectively provided with inverse teeth symmetrically distributed by taking the fixing slots as a center and upwardly inclining; the net band and the support rod are in detachable connection by the fixing slots. The sand barrier manufactured by utilizing the waste polyester net has the advantages of being convenient in construction, low in production cost, uneasy to fall, scatter, corrode and discompose, long in service life, capable of realizing the comprehensive utilization of wastes, energy-saving and environment-friendly.
Description
technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a windbreak and sand fixation technology, in particular to a sand barrier prepared by using waste polyester nets and its preparation and construction methods. Background technique [0002] Since the 1950s, 670,000 hectares of arable land, 2.35 million hectares of grassland and 6.39 million hectares of forest land have been turned into sandy land in China. In places such as the Houshan area of Ulanqab City in the Inner Mongolia Autonomous Region, the Alashan area, the lower reaches of the Tarim River in the Xinjiang Uygur Autonomous Region, the Qaidam Basin in Qinghai Province, the Bashang area in Hebei Province, and the Nagqu area in the Tibet Autonomous Region, the average increase in desertification areas has exceeded 4%. Due to the looming sandstorm, thousands of herdsmen were forced to relocate to other places and became "ecological refugees". According to t...
