Turbulent flow type sand blocking wall
The invention discloses a turbulent flow type sand blocking wall. The wall comprises two stand columns arranged side by side, an upper sand blocking net and a lower sand blocking net are installed between the two stand columns, a middle turbulent flow layer is further installed between the two stand columns, the middle turbulent flow layer is located between the upper sand blocking net and the lower sand blocking net, the lower sand blocking net is located below the middle turbulent flow layer, and when the device is used, a bottom reserved layer is arranged between the lower sand blocking netand the ground. The sand blocking wall can change the structure of sand flow, consume wind energy, enable the wind speed of the sand flow to be reduced rapidly, weaken the energy of sand grains driven by the air flow, enable a large number of sand grains to deposit near the sand blocking wall and form accumulated sand. Accumulated sand deposited near the sand blocking wall can be quickly transported away from the sand blocking wall, so that the service life of the sand blocking wall is prolonged, and the maintenance cost is reduced. The sand blocking wall is convenient to construct, low in manufacturing cost, high in sand prevention benefit and wide in application range, and the sand prevention requirement of engineering construction is met.
本发明公开了一种扰流式挡沙墙，包括并排设置的两根立柱，两根立柱之间安装有上部阻沙网和下部阻沙网，两根之间还安装有中部扰流层，中部扰流层位于上部阻沙网和下部阻沙网之间，下部阻沙网位于中部扰流层下方，使用时，下部阻沙网与地面之间有底部预留层。该挡沙墙能改变风沙流结构，损耗风能，使风沙流的风速迅速下降，削弱气流带动沙粒的能量，使大量沙粒沉积在挡沙墙附近，形成积沙。并能使沉积在挡沙墙附近的积沙快速运离挡沙墙附近，提高挡沙墙的使用寿命，减少养护成本。该挡沙墙施工便捷、造价低、防沙效益高、适用范围广，满足工程建设的防沙需求。
