Technical Field

[0001] The utility model relates to the technical field of mine slope protection, in particular to a mine slope protection net structure. Background Art

[0002] Open-pit mines are not covered with green rock for a long time, especially under the influence of external adverse factors such as acid rain. On the one hand, it is difficult to meet the requirements of green mines due to environmental protection issues. On the other hand, the weathering of the slope rock may cause landslides on the open-pit mine slopes, causing serious harm and losses to the safety of miners, national property and mineral resources. Therefore, it is necessary to cover the slopes with green. Most slopes are covered with green by opening planting troughs on the slopes and then laying wire mesh to achieve the effect of fixing the green cover. However, the wire mesh is not a complete wire mesh during the laying process and needs to be spliced.

[0003] The wire mesh is usually fixed on the slope with anchor rods. There are joints between adjacent wire meshes, and the edges of the wire mesh are rough and raised. When workers walk, their legs may be easily scratched, posing a safety hazard.

[0004] Therefore, it is necessary to provide a mine slope protection net structure to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0022] like Figure 1-3 As shown, the mine slope protection net structure provided by the utility model comprises: a protection net body 1, a horizontal fixing plate 2, a vertical fixing plate 3 and a plurality of anchor rods 4. The protection net body 1 is welded by a plurality of evenly arranged horizontal ribs and longitudinal ribs. The horizontal fixing plate 2 and the vertical fixing plate 3 are installed at least at the joint of two adjacent protection net bodies 1. The horizontal fixing plate 2 and the vertical fixing plate 3 are fixed on the slope surface by buried anchor rods 4. The horizontal fixing plate 2 is triangular in shape as a whole, and a plurality of first anti-slip grooves 6 and limiting grooves 7 are opened on it. The vertical fixing plate 3 is an inverted U-shaped structure as a whole, and a horizontal fixing groove 7 is opened at the bottom. A plurality of second anti-skid grooves 11, the spacing between the first anti-skid groove 6 and the second anti-skid groove 11 is consistent with the spacing between the transverse reinforcement and the longitudinal reinforcement on the protective net body 1. When in use, a planting groove is opened on the slope and filled with soil, and the protective net body 1 is laid on the soil layer. At the transverse intersection of the protective net body 1, a transverse fixing plate 3 is installed, so that the edge of the protective net body 1 located on the upper layer is located in the limited groove 7, and at least one transverse reinforcement is located in the limited groove 7. The longitudinal reinforcement of the protective net body 1 is inserted into the first anti-skid groove 6, and a plurality of anchor rods 4 are driven into the rock layer at the joint of the protective net body 1. The anchor rods 4 are used to fix the protective net body 1. The horizontal fixing plate 2 is fixed above the soil layer. Since the longitudinal reinforcement is stuck in the first anti-skid groove 6, the protective net body 1 cannot move laterally. Similarly, at the vertical intersection of the protective net body 1, the vertical fixing plate 2 is installed so that the edge of the protective net body 1 located on the upper layer is located below the vertical fixing plate 3. At least one longitudinal reinforcement on the edge of the protective net body 1 is located below the vertical fixing plate 3, and the horizontal reinforcement of the protective net body 1 is stuck in the second anti-skid groove 11. The vertical fixing plate 3 is also fixed above the soil layer using the anchor rod 4. Since the horizontal reinforcement is stuck in the second anti-skid groove 11, the protective net body 1 cannot move along the slope. For longitudinal movement, the installation density of the horizontal fixing plates 2 and the vertical fixing plates 3 can also be increased on the protective net body 1, so that the joints of the protective net body 1 are completely covered and fixed by the horizontal fixing plates 2 and the vertical fixing plates 3, and the edges of the protective net body 1 will not be exposed, avoiding the risk of people being scratched by the edges of the protective net body 1 when passing by, and through the first anti-slip groove 6 and the second anti-slip groove 11, the connection between the protective net body 1 and the horizontal fixing plates 2 and the vertical fixing plates 3 is made more stable, which limits the horizontal and vertical movement of the protective net body 1, thereby making the protective net body 1 less likely to move and more stable.

[0023] By providing a protective net body 1, a horizontal fixing plate 2, a vertical fixing plate 3 and a plurality of anchor rods 4, the potential safety hazard of burrs rising at the joints of the protective net can be avoided. A first anti-slip groove 6 and a second anti-slip groove 11 are respectively provided on the horizontal fixing plate 2 and the vertical fixing plate 3. The horizontal fixing plate 2 and the vertical fixing plate 3 are used to limit the protective net, thereby improving the stability of the protective net during use.

[0024] Embodiment 2:

[0025] like Figure 1-2 As shown, a retaining surface 5 is provided on the transverse fixing plate 2, and the retaining surface 5 is arranged at the top position of the transverse fixing plate 2. During the installation process of the transverse fixing plate 2, the inner side of the retaining surface 5 is low and the outer side is high, forming an inclined state. The top of the slope forms a raised inwardly inclined slope on the retaining surface 5. Therefore, the water and soil lost on the slope will gather on the retaining surface 5, reducing the downward discharge of soil, which is beneficial to improving the soil fixing effect of the protective net.

[0026] The soil retaining surface 5 is provided on the transverse fixing plate 2, so as to improve the soil fixing effect of the protection net and reduce soil and water loss.

[0027] Embodiment 3:

[0028] like Figure 2 As shown, the transverse fixing plate 2 is provided with a plurality of mounting grooves 8, and the mounting grooves 8 are provided with a first mounting hole 9, and the vertical fixing plate 3 is provided with a plurality of second mounting holes 12 which are consistent with the specifications of the first mounting holes 9. When in use, the anchor rod 4 is driven into the rock formation from the first mounting hole 9 and the second mounting hole 12, and the tail end of the anchor rod 4 remaining in the first mounting hole 9 and the second mounting hole 12 is connected to the transverse fixing plate 2 and the vertical fixing plate 3 by using a nut, so that the transverse fixing plate 2 and the vertical fixing plate 3 can be fixed. Due to the effect of the mounting groove 8, the nut and the tail end of the anchor rod 4 will not protrude and be exposed, so it is not easy to trip walking staff.

[0029] By providing the first mounting hole 9 and the second mounting hole 12 , it is possible to facilitate drilling of the anchor rod 4 , so as to fix the transverse fixing plate 2 and the vertical fixing plate 3 .

[0030] Embodiment 4:

[0031] like Figure 1 and 3 As shown, a plurality of steps 10 are evenly installed on the vertical fixing plate 3, and the step 10 is arranged on the side of the second mounting hole 12, which can block the exposed tail of the anchor rod 4 and the nut. When the soil has a lot of moisture, the workers walk on the soil layer, and the soles of their feet are easily contaminated by thick and slippery soil. Therefore, the workers can walk on the step 10, or walk on the retaining surface 5, and the soles of their feet are not easily contaminated by soil, which can also play an anti-slip role.

[0032] By evenly installing a plurality of steps 10 on the vertical fixing plate 3, the tail of the anchor rod 4 can be blocked, making it convenient for operators to walk on the slope.

[0033] Working principle: When in use, a planting groove is opened on the slope surface and filled with soil, and the protective net body 1 is laid on the soil layer. The overlapping is adopted at the intersection of two adjacent protective net bodies 1, that is, the edge of one protective net body 1 is laid above the edge of the other protective net body 1, and the horizontal fixing plate 3 is installed at the horizontal intersection of the protective net body 1, so that the edge of the protective net body 1 located on the upper layer is located in the limiting groove 7, and at least one transverse reinforcement is located in the limiting groove 7, and the longitudinal reinforcement of the protective net body 1 is stuck in the first anti-skid groove 6, and several anchor rods 4 are driven into the rock layer at the joint of the protective net body 1, and the horizontal fixing plate 2 is fixed above the soil layer with the anchor rods 4. Since the longitudinal reinforcement is stuck in the first anti-skid groove 6, the protective net body 1 cannot move laterally. Similarly, at the vertical intersection of the protective net body 1, a vertical fixing plate 2 is installed, so that the edge of the protective net body 1 located on the upper layer is located below the vertical fixing plate 3. At least one longitudinal reinforcement on the edge of the protective net body 1 is located below the vertical fixing plate 3, and the transverse reinforcement of the protective net body 1 is inserted into the second anti-slip groove 11. The vertical fixing plate 3 is also fixed above the soil layer using the anchor rod 4. Since the transverse reinforcement is inserted into the second anti-slip groove 11, the protective net body 1 cannot move longitudinally along the slope. The installation density of the transverse fixing plate 2 and the vertical fixing plate 3 can also be increased on the protective net body 1. Therefore, the joints of the protective net body 1 are completely covered and fixed by the transverse fixing plate 2 and the vertical fixing plate 3. The edge of the protective net body 1 will not be exposed, avoiding the risk of people being scratched by the edge of the protective net body 1 when passing by. In addition, through the first anti-slip groove 6 and the second anti-slip groove 11, the connection between the protective net body 1 and the transverse fixing plate 2 and the vertical fixing plate 3 is made more stable, which limits the lateral and longitudinal movement of the protective net body 1, thereby making the protective net body 1 less movable and more stable.
