Double-layer turbulent flow type snow blocking wall

Abstract

The invention discloses a double-layer turbulent flow type snow blocking wall. The wall comprises two stand columns arranged side by side. A first snow blocking net, a first spoiler, a second snow blocking net, a second spoiler and a third snow blocking net are sequentially arranged between the two stand columns from top to bottom. Gaps are formed between the first spoiler and the first snow blocking net and between the first spoiler and the second snow blocking net, gaps are formed between the second spoiler and the second snow blocking net and between the second spoiler and the third snow blocking net, when the snow blocking device is used, the third snow blocking net is adjacent to the ground, and gaps are formed between the third snow blocking net and the ground. The snow blocking wallis high in snow blocking efficiency, long in service life, capable of reducing maintenance cost, wide in application range, capable of adapting to various complex working conditions and capable of meeting the snow prevention requirement of engineering construction.

Description

technical field [0001] The invention belongs to the technical field of engineering snow prevention, and relates to a flow-disturbing snow-retaining wall. Background technique [0002] Wind blowing snow is a multi-phase flow weather phenomenon in which scattered snow particles are carried by the airflow and run near the ground. It is a relatively complex special fluid, which is very harmful to the driving of vehicles. [0003] With the rapid development of economic construction in the western region of my country, infrastructure construction such as railways, highways, and urban development has been widely carried out in the windy and snowy areas of Northwest my country. However, wind blowing snow is more harmful to railways and highways. If necessary protective measures are not taken, it will cause serious damage to infrastructures such as railways and highways, and even threaten the safe operation of infrastructures. [0004] The existing engineering snow prevention measur...

AI Technical Summary

Problems solved by technology

Among them, the snow prevention measures include steel structure snow retaining walls, PE nets, etc. These engineering snow prevention measures have played a certain role in the prevention and control of wind and snow disasters such as existing railways and highways, but there are generally difficulties in construction, high cost, Problems such as low snow protection efficiency

Especially when snow protection is carried out in strong wind areas such as "Baili wind area" and "Yandun wind area", the snow blocking measures in the prior art have problems such as low snow prevention benefit and high maintenance cost
