Description

Technical Field

[0001] The utility model relates to the technical field of road protection, in particular to a snow barrier used along a road. Background Art

[0002] Avalanche is a very serious natural disaster, widely distributed in the snowy mountainous areas at high latitudes and altitudes in my country. When an avalanche occurs, it will cause great damage to the structures along the roads (railways, highways), and thus cause huge economic losses. Avalanche disasters mainly occur in the Tianshan area. There are a large number of avalanche disasters along the newly built Yi'an Railway, the Jingyihuo Railway expansion and reconstruction project, and the Dushanzi to Kuche Expressway. How to form effective prevention and control measures and systems for the management of avalanche disasters is an urgent problem to be solved in order to avoid and mitigate avalanche disasters during road construction.

[0003] Snow barriers are simple block-shaped obstacles designed and used for avalanche dynamics. They are built in the valley path restricted by the valley wall, facing the direction of the avalanche or its direction perpendicular to the direction of the avalanche, so as to reduce the speed of the avalanche and shorten the throw distance, thereby avoiding endangering the protected area. Snow barriers intercept avalanche snow, aiming to reduce the amount of snow accumulated on the road (highway, railway) and shorten the snow clearing time.

[0004] However, the existing snow-blocking structures have poor stability. For example, a road sand and snow blocking device disclosed in Chinese invention patent publication number CN109024326A only uses steel columns, foundations, and sand and snow blocking plates to block snow. The device has poor stability and is weak in its ability to withstand avalanche impacts. It can be easily submerged by avalanche impacts and has no protective effect. Utility Model Content

[0005] The utility model aims to provide a snow barrier dam for use along roads, which is easy to build, simple to construct, has strong stability and ability to withstand avalanche impacts, and has a good snow barrier effect.

[0006] The utility model is achieved in this way:

[0007] A snow barrier dam for use along a road comprises a dam body arranged below the ground of an existing hillside, and the dam body is arranged perpendicular to the existing hillside, a slope protection is fixedly laid on the snow-facing side of the dam body, an earth ditch is opened on the slope body of the existing hillside, and the earth ditch is arranged on the side of the slope protection away from the dam body.

[0008] Furthermore, the dam body is in the shape of a prism with a horizontal cross-sectional area gradually increasing from bottom to top.

[0009] Furthermore, the slope protection is in the shape of a prism with a horizontal cross-sectional area gradually increasing from bottom to top.

[0010] Furthermore, plants are planted on the existing hillside, and the plants are planted on the side of the dam body away from the slope protection.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In actual application, the dam body is set below the ground of the existing hillside and perpendicular to the existing hillside. Combined with the slope protection laid close to the dam body, the overall stability of the structure is guaranteed, and the ability to withstand avalanche impact is enhanced. Soil is taken from the foot of the existing hillside on the side of the slope protection away from the dam body to form a soil ditch, which can save construction costs and increase the effective protection area. The utility model is easy to build, simple to construct, has strong stability and ability to withstand avalanche impact, and has a good snow blocking effect. BRIEF DESCRIPTION OF THE DRAWINGS
