Wind-gathering wind and sand retaining wall

Abstract

The invention provides a wind-gathering type wind-proof and sand-retaining wall, which comprises two uprights arranged side by side, a wind-gathering board and a wind-shielding board are arranged between the two uprights, there is a gap between the wind-gathering board and the wind-shielding board, and the top of the upright 1. The top of the wind accumulating plate is flush with the top of the wind deflector, and the position of the lower end surface of the wind accumulating plate is higher than that of the lower end surface of the wind deflector. The wind and sand retaining wall can effectively take into account both sand and wind protection at the same time, and gets rid of the shortcoming that the original wind and sand retaining device cannot efficiently take into account the wind and sand protection at the same time. It can use its own wind gathering gap to weaken the airflow velocity at the top of the sand retaining wall, reduce the number of sand particles jumping over the wind retaining wall, and improve the sand control efficiency. Assembled structure, fast installation speed, simple construction, and mass production.

Description

technical field [0001] The invention belongs to the technical field of engineering wind and sand protection, and relates to a wind and sand protection facility, in particular to a wind gathering type wind and sand protection wall. Background technique [0002] Wind erosion and wind accumulation are the basic manifestations of wind and sand activities in arid and semi-arid areas. They not only shape the surface morphology of desert areas, but also pose serious threats to people's production and life. For example, the sand carried by the wind reduces the visibility of the atmosphere, affects transportation, damages plants and wires, wears out buildings and machines, blows away organic matter on the soil surface, and reduces soil nutrients. Due to global warming and intensified human activities, more and more land has become bare land, which intensifies the process of desertification in arid and semi-arid regions. Land desertification and sandstorms are a major environmental p...

Problems solved by technology

However, the above-mentioned projects can only be applied to areas where sand damage is greater than wind damage. In desert areas with strong winds (wind force can reach more than 60m / s), these measures are stretched, because compared with sand damage, strong winds have a greater impact on road transportation. influence more than

For example, a series of problems occurred during the wind and sand protection process of the Lanxin high-speed railway. In order to ensure that the train would not be blown over by the strong wind, a non-ventilated windshield wall was built on the shoulder of the road. Particles jump over the windshield and deposit on the line, which seriously threatens the safe operation of the train. If a ventilated windshield is used, although the sand prevention efficiency is greatly improved, the probability of the train being blown over by the strong wind increases sharply
