Description
Technical Field
[0001] The utility model belongs to the field of protection equipment, in particular to a protection device with a rockfall prevention structure. Background Art
[0002] The high and steep slope protection device is a structure used to prevent rockfall on high and steep slopes and protect the safety of personnel, facilities and environment under the slope. The current high and steep slope protection device has many shortcomings. First, due to the lack of a special anti-rockfall structure, it is impossible to effectively block rockfall in areas where rockfall occurs frequently, causing the rockfall to roll down and threaten the safety of personnel and facilities. This shortcoming is mainly due to insufficient risk assessment of rockfall during design, and the geological conditions of the slope and the potential scale of rockfall are not fully considered. The conventional response method is to manually clean and repair after the rockfall occurs, but this method is not only inefficient but also highly dangerous. At the same time, if the rockfall cannot be effectively intercepted, it will easily roll down to the area below, endangering the lives of personnel and the safety of facilities. This is mainly due to the fact that the movement trajectory and impact force of the rockfall were not fully considered at the beginning of the design, and the anti-rockfall function was ignored. The conventional response method is to arrange personnel to patrol and set up warning signs after the rockfall occurs, but this method is manpower-consuming and difficult to monitor in real time, so it is necessary to propose a new structure to solve the above technical problems. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide a guarding device with an anti-rockfall structure to solve the problems raised in the above-mentioned background technology.
[0004] The utility model is realized through the following technical scheme: a guarding device with an anti-rockfall structure comprises: a slope body, a slope bottom and a protective net, the upper surface of the slope bottom is the slope body, the right side surface of the slope body is the slope surface, a plurality of protective nets are installed on the surface of the slope surface, a plug plate is welded on the lower surface of the lowest side of the protective net, a concrete block is cast on the outer surface of the plug plate through the slope body, an anchor rope is installed between the protective net and the slope body through a hanging ring, an anchor rod is installed between the protective net and the slope body, one end of the anchor rod away from the protective net is inserted into the inside of the slope body, the protective net comprises: a frame, a connecting plate, a grid and an elastic steel wire mesh, the upper surface and the lower surface of the frame are installed with a connecting plate, the inside of the frame is installed with a grid, and the front side surface and the rear side surface of the frame are symmetrically installed with elastic steel wire mesh.
[0005] As a preferred embodiment, a protective net is inserted into the lower edge of the inclined surface of the slope through a plug plate, and a plurality of fixing pins are inserted on the surface of the plug plate at 90 degrees perpendicular to the plug plate. The protective net is fixed to the surface of the slope through the plug plate, concrete blocks and fixing pins.
[0006] As a preferred embodiment, multiple protective nets are installed on the upper surface of the protective net through a connecting plate. The protective nets are set at 90 degrees perpendicular to the bottom of the slope. A pair of anchor ropes and anchor rods are set on both side edges of the inner surface of each protective net, and multiple groups of lifting rings are installed on the surface of the slope through inserted rods.
[0007] As a preferred embodiment, the number of the lifting rings matches the number of anchor ropes, the length of the inserted rod is greater than the length of the corresponding anchor rope, the anchor rod is arranged at a vertical angle of 90 degrees to the slope surface, the number of the anchor rods matches the number of anchor ropes, the anchor rods penetrate deep into the slope, and provide a firm anchoring point for the protective net, effectively resisting the displacement and deformation that may occur in the protective net when impacted by falling rocks. At the same time, the anchor ropes are connected to the protective net and the slope, providing tension from different directions, further enhancing the overall stability of the protective net, reducing structural damage caused by local uneven force, and the huge force generated when falling rocks impact the protective net can be evenly dispersed to the slope through the anchor rods and anchor ropes, avoiding damage to the protective net due to excessive local force.
[0008] As a preferred embodiment, a grid is installed at the center position inside the frame, and the elastic steel wire mesh member includes: a mounting frame and an elastic steel wire mesh body. The mounting frame is a U-shaped structure, and the elastic steel wire mesh body is installed inside the mounting frame. The front and rear surfaces of the frame are installed with the elastic steel wire mesh body via the mounting frame.
[0009] As a preferred embodiment, the aperture of the mesh of the elastic wire mesh body is larger than the aperture of the mesh of the grid, and the height of the protective net is proportional to the height of the slope. The protective net composed of the grid and the elastic wire mesh provides a double protection barrier. The elastic wire mesh can block larger falling rocks, while the internal grid can block smaller falling rocks. The elastic wire mesh can absorb part of the energy through its own elastic deformation when the falling rocks impact, thereby further reducing the damage to the protective net and the slope caused by the falling rocks.
[0010] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by arranging an anchor rope and an anchor rod, an anchor rope is installed between the protective net and the slope through a lifting ring, an anchor rod is installed between the protective net and the slope, and one end of the anchor rod away from the protective net is inserted into the inside of the slope. When in use, the anchor rod goes deep into the inside of the slope, providing a firm anchoring point for the protective net, effectively resisting the displacement and deformation that may occur in the protective net when impacted by falling rocks. At the same time, the anchor rope is connected to the protective net and the slope, providing tension from different directions, further enhancing the overall stability of the protective net, reducing structural damage caused by local uneven force, and the huge force generated when falling rocks impact the protective net can be evenly dispersed to the slope through the anchor rod and the anchor rope, avoiding damage to the protective net due to excessive local force.
[0011] By setting up a protective net, multiple protective nets are installed on the surface of the slope, a plug plate is welded on the lower surface of the lowest protective net, and concrete blocks are cast on the outer surface of the plug plate through the slope. The protective net includes: a frame, a connecting plate, a grid and an elastic steel wire mesh. The upper and lower surfaces of the frame are installed with connecting plates, the inside of the frame is installed with a grid, and the front and rear surfaces of the frame are symmetrically installed with elastic steel wire mesh. When in use, the protective net composed of the grid and the elastic steel wire mesh provides a double protective barrier. The elastic steel wire mesh can block larger falling rocks, while the internal grid can block smaller falling rocks, and the elastic steel wire mesh can absorb part of the energy through its own elastic deformation when the falling rocks impact, thereby further reducing the damage of the falling rocks to the protective net and the slope.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 3 The utility model provides a technical solution: a protective device with an anti-rockfall structure, comprising: a slope body 100, a slope bottom 110 and a protective net 200, the upper surface of the slope bottom 110 is the slope body 100, the right side surface of the slope body 100 is the slope surface, a plurality of protective nets 200 are installed on the surface of the slope surface, a plug plate 201 is welded on the lower side surface of the lowest protective net 200, a concrete block 130 is cast on the outer surface of the plug plate 201 through the slope body 100, and a hanging plate 130 is cast between the protective net 200 and the slope body 100. The ring 320 is installed with an anchor rope 330, an anchor rod 300 is installed between the protective net 200 and the slope 100, and the end of the anchor rod 300 away from the protective net 200 is inserted into the slope 100. The protective net 200 includes: a frame 210, a connecting plate 220, a grid 230 and an elastic steel wire mesh. The connecting plate 220 is installed on the upper and lower surfaces of the frame 210, the grid 230 is installed inside the frame 210, and the front and rear surfaces of the frame 210 are symmetrically installed with elastic steel wire mesh.
[0021] See also Figures 1 to 3 As the first embodiment of the utility model: the lower side edge of the slope of the slope body 100 is inserted with a protective net 200 through a plug plate 201, and a plurality of fixing pins 120 are inserted on the surface of the plug plate 201 at a 90-degree angle perpendicular to the plug plate 201, and the protective net 200 is fixed to the surface of the slope through the plug plate 201, the concrete block 130 and the fixing pins 120;
[0022] A plurality of protective nets 200 are installed on the upper surface of the protective net 200 through a connecting plate 220. The protective net 200 is arranged at a 90-degree vertical angle to the slope bottom 110. A pair of anchor ropes 330 and anchor rods 300 are arranged on both side edges of the inner surface of each protective net 200. A plurality of sets of lifting rings 320 are installed on the surface of the slope through an insertion rod 310.
[0023] The number of the lifting rings 320 matches the number of the anchor ropes 330, the length of the insertion rod 310 is greater than the length of the corresponding anchor rope 330, the anchor rod 300 is arranged perpendicular to the slope at 90 degrees, and the number of the anchor rod 300 matches the number of the anchor ropes 330;
[0024] When in use, when the protective net 200 is fixed to the surface of the slope through the plug plate 201, the concrete block 130 and the fixing pin 120, the user can then cumulatively install multiple protective nets 200 upwards in sequence through the connecting plate 220 according to the height of the slope 100. After the installation is completed, the user can insert multiple lifting rings 320 on the surface of the slope 100 through the plug rod 310. The number of installed lifting rods matches the number of anchor ropes 330. After the installation of the lifting ring 320 and the protective net 200 is completed, the user can first symmetrically install the anchor rod 300 on the rear surface of the protective net 200, and then insert the end of the anchor rod 300 away from the protective net 200 into the inside of the slope 100. After the insertion is completed, the user can install the anchor rope 330 under the anchor rod 300 so that the end of the anchor rope 330 away from the protective net 200 is connected to the lifting ring 320. The anchor rope 330 is connected to the protective net 200, and at the same time, the anchor rope 330 is in a slightly bent, not completely straightened state (the purpose is to provide a certain stress for the bent anchor rope 330 to prevent the straightened anchor rope 330 from breaking when the protective net 200 is hit by falling rocks). Since the anchor rod 300 penetrates deep into the slope 100, a firm anchoring point is provided for the protective net 200, which effectively resists the displacement and deformation that may occur in the protective net 200 when impacted by falling rocks. At the same time, the anchor rope 330 is connected to the protective net 200 and the slope 100 to provide tension from different directions, which further enhances the overall stability of the protective net 200 and reduces structural damage caused by local uneven force. The huge force generated when falling rocks impact the protective net 200 can be evenly dispersed to the slope 100 through the anchor rod 300 and the anchor rope 330, avoiding the protective net 200 from being damaged due to excessive local force.
[0025] See also Figures 1 to 3 As a second embodiment of the utility model: a grid 230 is installed at the center of the frame 210, and the elastic steel mesh member includes: a mounting frame 240 and an elastic steel mesh body 250, the mounting frame 240 is a square-shaped structure, and the elastic steel mesh body 250 is installed inside the mounting frame 240, and the front side surface and the rear side surface of the frame 210 are installed with the elastic steel mesh body 250 through the mounting frame 240;
[0026] The aperture of the mesh of the elastic steel wire mesh body 250 is larger than the aperture of the mesh of the grid 230, and the height of the protection net 200 is proportional to the height of the slope 100;
[0027] When in use, when rocks fall from the surface of the slope 100, the protective net 200 will block the rocks falling from the slope 100. Larger rocks will first be blocked by the elastic wire mesh body 250, and then smaller gravels will pass through the elastic wire mesh body 250 and be blocked by the grid 230. Since the protective net 200 composed of the grid 230 and the elastic wire mesh provides a double protective barrier, the elastic wire mesh can block larger rocks, and the internal grid 230 can block smaller rocks. The elastic wire mesh can absorb part of the energy through its own elastic deformation when the rocks hit, further reducing the damage of the rocks to the protective net 200 and the slope.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
