| 摘 要： | 高立式移动沙障的栅栏障体采用18号铁丝将Φ1.0~Φ1.2cm树枝编织成长2m、宽1m,孔隙度为40%~60%的阻沙栏,用扁铁做阻沙栏的腰条,用移动管卡连接立柱与障体,安装于流动沙丘丘顶、丘间低地、迎风坡等部位。经过研究后发现:传统上采用的各种高立式沙障扎设完成后,因沙障不能移动,栅栏障体被动地被风蚀或沙埋,不仅降低了防护效果,而且使用寿命较低。高立式移动沙障的栅栏障体既能沿立柱上下移动,又可以根据流沙的危害整体移动,达到因害设防的目的,机动灵活地阻截流沙,推广应用的价值较高。还提出了高立式移动沙障的设计原理及制作安装方法。

| Abstract: | The high vertical mobile sand-barriers is made up from using the no.18 iron wire to weave branches (1~1.2 cm) into the sand-barriers which are 2 m long and l m wide and with 40~60 porosity; then using flat iron as their waist strips, and using moving tube clips to connect the upright column and the barriers; lastly setting up them on the moving dune top, intervals and windward slopes. Testing result shows that the traditional barriers might be eroded or covered up by sand because they aren't movable, therefore not only the protective effect is reduced but also the standing life is shortened. In comparison, the type of high vertical mobile sand-barrier can move vertically and horizontally, which can bring it into play according to the circumstance. It is of great value for generalization and application due to its conveniency in practicing. This paper has also presented the design principle and the method of its manufacture and installation. |
