Windproof sand-blocking device for windy and sandy area and windy and sandy area roadbed sandstorm protection system
The invention relates to the field of sandstorm prevention and control, and provides a windproof sand-blocking device for a sandstorm area and a sandstorm prevention system for a sandstorm area roadbed. The device comprises a blocking part, a blocking net part arranged above the blocking part and an intercepting fence which is located at the top of the blocking net part and extends towards the windward side from the top of the blocking net part. The blocking part comprises a plurality of blocking bodies and fixing stand columns for fixing every two adjacent blocking bodies. The blocking net part comprises a plurality of blocking nets and fixing supporting columns for fixing every two adjacent blocking nets, and the blocking nets are installed at the tops of the fixing supporting columns through the fixing supporting columns. The intercepting fence comprises a fixing support and an intercepting net installed on the fixing support, the intercepting net is installed on the side, located on the windward side, of the fixing supporting column through the fixing support, and an included angle is formed between the intercepting net and the blocking net. By the adoption of the structure that the upper portion is sparse and the lower portion is dense, disturbance to wind and sand flow can be reduced to the maximum extent while sand blocking, wind blocking, dust suppression and withered grass blocking are effectively achieved, local airflow stability is guaranteed to the maximum extent, and the protection effect on a windy and sandy area is improved.
本发明涉及风沙防治领域，提供风沙区用防风阻沙装置及风沙区路基风沙防护体系。该装置包括阻挡部和设于阻挡部上方的阻网部以及位于阻网部顶部并由阻网部顶部朝向迎风侧延伸的拦截栅栏；阻挡部包括多个阻挡本体以及固定相邻两个阻挡本体的固定立柱；阻网部包括多个阻网以及固定相邻两个阻网的固定支柱，阻网通过固定支柱安装于固定立柱的顶部；拦截栅栏包括固定支架和安装在固定支架上的拦截网，拦截网通过固定支架安装在固定支柱的位于迎风侧的一侧，拦截网与阻网呈夹角设置。本发明采用“上疏下密”的结构，能够在有效阻沙、挡风、抑尘、拦枯草的同时，最大程度减小对风沙流的扰动，并最大程度地保证局地气流稳定，提高对风沙区的防护作用。
