Geotechnical slope reinforcing device

Abstract

The invention relates to the technical field of slope reinforcing and in particular relates to a geotechnical slope reinforcing device. The geotechnical slope reinforcing device is characterized by comprising a steel strand, a reinforcing rib and barbs, wherein one section of the reinforcing rib is cylindrical and the other section of the reinforcing rib is conical; the plurality of barbs are fixedly welded on the cylindrical section of the reinforcing rib along a side wall of a curved surface of the reinforcing rib; the reinforcing rib and the barbs are made of reinforcing bars; one end of the steel strand is fixedly connected with the section of the cylindrical section of the reinforcing rib; the tops of the barbs are inclined towards one side of the steel strand. The geotechnical slope reinforcing device has the advantages of good anti-shearing property and anti-pulling property, and is suitable for reinforcing slopes in construction work processes of roads, railways, foundation pits and open-pit mines.

Description

【Technical field】 [0001] The invention relates to the technical field of slope reinforcement, in particular to a rock and soil slope reinforcement device. 【Background technique】 [0002] Slope landslides, sideslips, collapses and other factors are the main disastrous factors for slope damage. At present, anchoring technology is widely used in domestic construction of roads, railways, foundation pits, open-pit mines and other engineering practices to strengthen rock and soil slopes. The anchor rod used in the technology is generally a linear anchor bar, which has the disadvantages of uneven force on the slope and poor slope protection after the slope is reinforced, especially when the weathered rock and soil slope is reinforced, if the anchor If the anchorage depth of the rod is insufficient, the anchorage structure will be prone to instability and damage. Therefore, in engineering practice, the anchor rod is often required to have sufficient length and anchorage depth, which...

[0002] Slope landslides, sideslips, collapses and other factors are the main disastrous factors for slope damage. At present, anchoring technology is widely used in domestic construction of roads, railways, foundation pits, open-pit mines and other engineering practices to strengthen rock and soil slopes. The anchor rod used in the technology is generally a linear anchor bar, which has the disadvantages of uneven force on the slope and poor slope protection after the slope is reinforced, especially when the weathered rock and soil slope is reinforced, if the anchor If the anchorage depth of the rod is insufficient, the anchorage structure will be prone to instability and damage. Therefore, in engineering practice, the anchor rod is often required to have sufficient length and anchorage depth, which is not conducive to the overall stress of the anchor rod system. On the contrary, it makes the reinforcement The anchor bolt has poor shear resistance and cannot bear the bending moment and shear force caused by the slide of rock and soil, which may easily cause the anchor bolt to be broken and damaged. Therefore, only using anchor bolts to reinforce the slope does not have a good reinforcement effect.
