Roadbed wind and sand prevention facility capable of automatically adjusting wind and sand preventing direction in strong wind area of Gobi desert

Abstract

The invention relates to an engineering protection structure, in particular to a roadbed wind and sand prevention facility capable of automatically adjusting wind and sand prevention direction in a strong wind area of the Gobi. The roadbed wind and sand prevention facility capable of automatically adjusting the wind and sand prevention direction comprises a multi-span wind and sand prevention device which is arranged perpendicular to the predominant wind direction. Each span wind and sand prevention device comprises rotatable stand columns, an upper support rope and a lower support rope are installed between each two adjacent rotatable stand columns, a combined wind-proof mesh is installed between each upper support rope and each lower support rope, anchor pulling ropes are installed on two sides of each stand column, the upper end of each pulling rope is movably sleeved at the top end of each rotatable stand column, the lower ends of the anchor pulling ropes are fixed on a ground anchor, and the anchor pulling ropes, the upper support rope and the lower support rope are connected with decompression rings in a separated mode. The roadbed wind and sand prevention facility is arranged along the predominant wind direction, when the wind direction changes, the practical moving direction of the wind and sand prevention facility is automatically adjusted in a certain range and automatically located in the large wind direction, the wind and the sand are effectively prevented, and the aims of effective wind-sand disaster prevention and effective engineering work protection and effective engineering structure protection are achieved. The roadbed wind and sand prevention facility has the advantages of being simple in construction, convenient to construct, time-saving in maintenance and good in wind-sand protection effect.

Description

technical field [0001] The invention relates to an engineering protection structure, in particular to a roadbed wind and sand prevention facility capable of automatically adjusting the direction of wind and sand resistance in the Gobi strong wind area. Background technique [0002] Sandstorm diseases are widely distributed in my country. With the accelerated development of infrastructure construction in my country, various sandstorm diseases have become increasingly prominent in railway construction and operation, especially those in the Gobi windy region. Due to the periodic and sudden characteristics of wind and sand disease, it poses a great threat to the normal construction and operation of railway lines. Under the current technical level, in addition to adopting environmental protection measures, it is one of the most commonly used measures to select an effective wind and sand-proof structure for protection. Most of the commonly used sand-proof structures are rigid str...

Problems solved by technology

Most of the commonly used anti-wind and sand structures are rigid structures. Although some flexible structures are used in anti-wind and sand structures, the application effect of existing wind-proof structures is limited due to the unstable change of wind direction in sand-storm areas.
