Embodiment Construction

[0020] Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

[0021] The sandstorm disaster in the Hexi Corridor is serious, and the hazards of quicksand have not been effectively prevented for many years. In order to ensure the smooth operation of the traffic lines in this area and avoid the harm of wind and sand, the present invention implements a triangular sand embankment for the prevention and control of wind and sand.

[0022] like figure 1 As shown, a triangular sand dike for wind and sand control is arranged in the upwind direction of the object to be protected. It is characterized in that the section of the dike body is an isosceles triangle 1 with an inclination angle of 40°, and the height H of the dike body is 6.0-7.5 m, the length L of the embankment is equivalent to the length S of the protected object 2, and the maximum distance between the protected object 2 and the triangular sand dike 1 is 17 times t...

Abstract

The invention relates to a triangular sand control dam applied to prevention and treatment of sandstorm. The triangular sand control dam is arranged in windward direction of an object to be protected, the section of a dam body is in shape of an isosceles triangle with an inclination angle of 40 degrees, the height H of the dam body is 6.0-7.5m, the length L of the dam body is equal to the length S of the object to be protected, and the maximum space between the object to be protected and the sand control dam is the 17 times the height of the sand control dam. The invention provides a new type of a sand control engineering which can block wind-drift sand at a windward slope and can also form a large-range effective protective distance on the leeward side. The triangular sand control dam disclosed by the invention is already applied to the prevention and treatment of sandstorm at a second double-line Yumen section of Lanxin and obtains excellent sand control effect. Based on the practice, the triangular sand control dam with the inclination angle of 40 degrees exerts the excellent sand control effect and provides successful experience and theoretical direction for the prevention and the treatment of the sandstorm in gravel gobi, the maintenance of transport lines and the protection of important cultural objects and historic monuments and economic facilities in China.

Description

[0001] technical field [0002] The invention belongs to the technical field of wind and sand control, and in particular relates to a triangular sand-proof embankment for blocking and guiding wind-and-sand flow. Background technique [0003] With the continuous, stable and high-speed development of the national economy, the country has intensified its efforts to develop the western region, and the development level of transportation has become an important factor in promoting regional development. The Lanxin Second Double Line is the main part of the land bridge passage in the main framework of the national "eight horizontal and eight vertical" railway network. After completion, it will greatly shorten the space-time distance between the northwest region and the central, eastern and southwestern regions, and will improve the efficiency of transportation organization for operating companies It is of great significance to drive regional economic development and improve people'...
