Secondary sand accumulation prevention facility based on wind break wall
The invention relates to the technical field of wind and sand prevention of traffic facilities, in particular to a secondary sand accumulation prevention facility based on a wind break wall. The secondary sand accumulation prevention facility comprises a first wind break wall arranged on an embankment, a flat ground or a cutting, a second wind break wall is arranged on the leeward side of the first wind break wall of the embankment, the flat ground or the cutting, a sand intercepting ditch is dug in the leeward side of the second wind break wall, and meanwhile, an inclined plate is additionally arranged at the top of the first wind break wall for the cutting type with the most serious sand accumulation. By adopting the measures of arranging the second wind break wall, the sand interceptingditch and the inclined plate, the phenomenon that sand grains on the leeward side return to a line under the action of eddy current and form sand accumulation is effectively prevented, it is guaranteed that a train is not affected by strong wind and sand accumulation under different terrains, and high-speed and safe operation is achieved.
本发明涉及交通设施防风沙技术领域，具体涉及一种基于挡风墙的二次防积沙设施，包括在路堤、平地或路堑上设置的第一道挡风墙，在路堤、平地或路堑的第一道挡风墙背风侧设置第二道挡墙，并在第二道挡墙背风侧挖设截沙沟，同时针对积沙最严重的路堑式，在第一道挡风墙顶部加设斜板；通过采用设置第二道挡墙和截沙沟以及斜板的措施，有效的防止了背风侧沙粒在涡流的作用下返回至线路并形成积沙的现象，确保列车在不同地形下不受大风及积沙影响，高速、安全运行。
