Sloped sand guiding wall for roadbed
The invention discloses a sloped sand guiding wall for a roadbed. The sloped sand guiding wall comprises a first wind pressure plate, a second wind pressure plate, first supporting columns, second supporting columns and third supporting columns, wherein the lengths of the first supporting columns are shorter than those of the second supporting columns, the length of the second supporting columns are shorter than those of the third supporting columns, and the first supporting columns, the second supporting columns and the third supporting columns are vertically arranged; one end of the first wind pressure plate is fixed at the top ends of the first supporting columns, the other end of the first wind pressure plate is fixed at the top ends of the second supporting columns, one end of the second wind pressure plate is fixed at the top ends of the second supporting columns, the other end of the second wind pressure plate is fixed at the top ends of the third supporting columns, and the degree of an acute angle formed by the first wind pressure plate and a horizontal plane is larger than that of an included angle formed by the second wind pressure plate and the horizontal plane. According to the sloped sand guiding wall disclosed by the invention, air currents can flow out at a high speed at an outlet through the natural compression of air currents at an inlet, sand substances in wind sand flow are prevented from sedimentation influenced by the lifting of a road surface, railway sleepers or rails, sand stacked before the arrangement of a sand resistant wall can be blown away, power driving is not needed, and a decelerating region cannot be generated on a near-surface layer.
