Technical Field

[0001] This application relates to a slope anchoring device. Background Art

[0002] Slope geological disasters are inevitable during the process of human transformation of nature and are the most common type among many geological disasters encountered. Common geological disasters include: various types of engineering landslides, collapses and rockfalls, excavation and support of artificial slopes under various rock conditions, etc. The slope geological disasters in civil engineering construction in some areas of our country, such as: railway, highway, mine, municipal and other project works, are particularly serious. This requires taking various disaster prevention and mitigation measures according to local conditions in order to achieve good protection effects. Slope anchoring is a kind of slope protection measure, mainly a flexible net mainly composed of wire rope nets covering and wrapping on the required protected slope to limit the weathering and spalling of the rock and soil mass on the slope surface.

[0003] The traditional anchor rod is composed of a threaded steel bar and a nut. The anchor rod is inserted into the drilled anchor hole and then fixed in the rock mass with mortar. When the anchor rod is subjected to tension, the anchoring force only depends on the adhesion between the threaded steel bar and the concrete mortar, and the overall anchoring force is relatively low.

[0004] Therefore, it is desired to provide a slope anchoring device. Utility Model Content
