New Application of Corrugated Steel Structure – Shed Tunnel for Against Wind & Snow in The Wind District of Mayitas
In northern China (especially Xin’Jiang, Qing’Hai, and Tibet), avalanches,snowstorms,and other disasters often occur due to climatic reasons,which is a huge danger to road traffic safety. The harm of wind and snow to highway traffic is mainly to reduce visibility and cause snow cover on the road. The road maintenance department and the traffic management department need to invest a lot of power and money every year to prevent snow damage and ensure traffic safety. The corrugated steel shed is a device that can be used to prevent snow cover on the highway in some certain extent. It plays a vital role in road safety.
Xinjiang’s Tacheng area has good air quality, beautiful scenery, and unique humanities. It has always been a tourist destination that people long for. It should take 201 provincial road To get in and out of Tacheng area, and there is a Mayitas wind zone with a length of 40 kilometers on this road. The annual average winds greater than or equal to 8 are more than 150 days, up to 180 days, and the maximum wind speed is 40 Meters / second. Once it encounters a snowy day, the wind blows snowflakes and blocks the view. The snow formed by the wind blows snow up to 7-8 meters, which makes the road traffic closed and brings great inconvenience to people.
The corrugated steel structure shed is located on the section 201 provincial road from section Er’min to section Tie’Chang’Gou, which is the strongest wind. Its surface like a tunnel, which height 8.4meter, width 13meter and totally length 300meter. Mainly body is by 118PCS of cement column, wind break wall and corrugated steel structure , It is reinforced concrete frame structure, can withstand 12 strong winds, the main body life is 50 years. At the same time, a 330-meter snow net and a 510-meter snowboard were built around the shed.
This is the first snowstorm project in Xinjiang to be used on highways to study the effects of shed tunnels on the management of Mayitas snowstorm disasters. After observing the effects of a winter from 2018 to 2019, the shed tunnel project will be promoted in the entire section of the Mayitas wind-blown snow section, which will completely solve the problem that hinders the masses from traveling in winter.
The road corrugated steel plate shed can resist wind and snow disasters, avalanches and other disasters, ensure the protection of highway capacity when disasters occur, and effectively solve the problem of snow disasters on highway vehicles. It has the advantages of simple structure, convenient manufacturing and construction, low cost, fast construction speed, and superior mechanical properties. can be widely used in highway protection projects in heavy snow disaster sections, and can effectively solve the related problems existing in the highways prone to snow disaster. will certainly have a great leading role in the development of highway disaster prevention.
