Description

Technical Field

[0001] The present invention relates to the technical field of slope rolling stone protection, in particular to a soft and hard interlayer collapse protection structure. Background Art

[0002] The slope rock structure is a combination of soft and hard rock interlayers, distributed in a "mudstone-sandstone-mudstone" pattern from bottom to top. Under geological action, mudstone is more easily weathered and broken, thereby developing cavities. When cavities appear in mudstone, the upper sandstone body is prone to instability and collapse.

[0003] Currently, the protective measure for interbedded sandstone collapses involves installing staked nets at the foot of the slope in the sandstone collapse area to intercept rolling rocks and limit their movement. However, existing staked nets lack a temporary solution. When the net is damaged by excessive impact, it loses its ability to intercept rolling rocks and cannot continue to protect the area until the net is replaced or repaired. Summary of the Invention

[0004] In order to make up for the above shortcomings, the present invention provides a soft and hard interlayer collapse protection structure, which aims to improve the problems of the existing pile-type protection net lacking buffering capacity, poor protection performance, easy damage when subjected to excessive impact force, and lack of temporary remedial measures.

[0005] The present invention is achieved in that:

[0006] The invention provides a soft-hard interlayer collapse protection structure, which comprises a ground fixing mechanism and a rolling stone protection mechanism.

[0007] The ground fixing mechanism includes a fixing frame and a ground anchoring assembly, and the ground anchoring assembly is symmetrically arranged on the fixing frame.

[0008] The rock rolling protection mechanism includes a first protection net and a second protection net. Both sides of the first protection net are connected to the two fixing frames respectively, and both sides of the second protection net are connected to the two fixing frames respectively.

[0009] By setting up a second protective net behind the first protective net, small-volume gravel passing through the first protective net can be intercepted. When the first protective net is damaged, the second protective net can serve as a backup interception and continue to ensure the safety of the area, leaving sufficient time for the maintenance and replacement of the first protective net.

[0010] In one embodiment of the present invention, the fixing frame includes a bottom plate and side plates, and the side plates are fixed to the upper surface of the bottom plate.

[0011] In one embodiment of the present invention, the fixing frame further includes reinforcing ribs, which are fixed between the upper surface of the bottom plate and the bottom of the side wall of the side plate, thereby strengthening the connection strength between the side plate and the bottom plate and improving the overall impact resistance of the fixing frame.

[0012] In one embodiment of the present invention, the first protective net includes a first fixed plate and a first net body, the bottom and top of the first fixed plate are fixedly connected to the upper surface of the bottom plate and the top of the side plate respectively, and the edge of the first net body is fixedly connected to one side of the first fixed plate.

[0013] In an embodiment of the present invention, at least two first fixing plates are provided, the structures and sizes of the two first fixing plates are completely identical, and the first net body is fixed between the two first fixing plates.

[0014] In one embodiment of the present invention, the mesh diameter of the first mesh body is set to 150mm-250mm.

[0015] In one embodiment of the present invention, the second protective net includes a second fixing plate, a second net body and a connecting piece, one side of the second fixing plate is connected to the side plate through the connecting piece, and the edge of the second net body is fixedly connected to the second fixing plate.

[0016] In one embodiment of the present invention, at least two second fixing plates are provided, the two second fixing plates have exactly the same structure and size, and the second net body is fixed between the two second fixing plates.

[0017] In one embodiment of the present invention, the mesh diameter of the second mesh is set at 50mm-100mm, and the mesh diameter of the second mesh is smaller than the mesh diameter of the first mesh, which can intercept small-volume gravel passing through the first mesh.

[0018] In one embodiment of the present invention, the connecting member includes a sleeve, a first spring and a sliding rod, the sleeve is fixed to the side plate, one end of the sliding rod is connected to the inner wall of the sleeve through the first spring, and the other end of the sliding rod is fixedly connected to one side of the second fixed plate, so that the second fixed plate is elastically slidably connected to the side plate, thereby improving the buffering and protection capacity of the second net body.

[0019] The extreme situations that protective nets face during use generally fall into two categories: the anchor mechanism detaching from the ground and the net breaking. Either of these situations will cause the net to lose its interception capability. The anchor mechanism detaching from the ground is primarily due to insufficient anchoring reliability. When the net is impacted, the anchor mechanism initially becomes skewed, and then, under further impact from the rockfall, it detaches from the anchor holes, rendering the net unable to directly intercept the rockfall and causing the device to lose its interception capability.

[0020] In one embodiment of the present invention, the ground anchor assembly includes a first anchor and a second anchor, the first anchor includes an anchor rod, a first resistance rod, a first fixing frame, a first slider, a first fixing rod and an insertion rod, the anchor rod is fixed to the base plate, a first opening and a second opening are opened on the side of the anchor rod, the first resistance rod is hinged in the first opening, the first fixing frame is fixed to the side wall of the anchor rod inner cavity, the first slider is slidably set on the first fixing frame, the two ends of the first fixing rod are respectively hinged to the first resistance rod and the first slider, the insertion rod is slidably connected to the anchor rod inner cavity, the second anchor includes a second resistance rod, a second fixing frame, a second slider, a second fixing rod, a first pull rope and a second spring, a third opening is opened on the side of the insertion rod, the second resistance rod is hinged in the third opening, the second fixing frame is fixed to the side wall of the insertion rod inner cavity, the second slider is slidably set on the second fixing frame, the two ends of the second fixing rod are respectively hinged to the second resistance rod and the second slider, the upper surface of the second slider is fixedly connected to the first net body and the second net body by the first pull rope, and the two ends of the second spring are respectively fixedly connected to the lower surface of the second slider and the bottom of the insertion rod inner cavity.

[0021] By adopting the above scheme, the deformation of the first protective net is converted into the anchoring strength of the anchor rod in direct proportion through the second anchoring member. The greater the deformation, the more secure the anchoring. The second spring is also used to give the first protective net a certain degree of buffering protection capability. In conjunction with the first anchoring member, the overall anchoring reliability and impact resistance of the ground fixing mechanism are effectively improved, which can prevent the ground fixing mechanism from detaching from the ground when the net is hit by rolling stones, thereby ensuring the normal interception of rolling stones by the device.

[0022] In one embodiment of the present invention, the first pull rope includes a first connecting rope and a second connecting rope, the bottom end of the first connecting rope is fixed to the upper surface of the second slider, and the top end of the first connecting rope is fixedly connected to the first net body and the second net body through the second connecting rope.

[0023] In one embodiment of the present invention, the top and bottom ends of the channel in the insertion rod for the first connecting rope to pass through are both set to be chamfered, which reduces the friction resistance of the first connecting rope when it slides and reduces the wear and tear of the first connecting rope during use.

[0024] The mesh breaks because the impact force of the rockfall exceeds the upper limit of the mesh's protective capacity. Existing protective nets are generally used alone. When the net's rigid protection is high but its buffering capacity is low, the net's initial protection is strong, it can withstand high direct impact forces, and can quickly intercept rockfalls. However, each impact significantly reduces the durability of the mesh's braided ropes, resulting in a short mesh lifespan and a rapid decline in protective capacity. When the net's buffering capacity is strong but its rigid protection is too low, the mesh deforms significantly under impact, and its ability to withstand direct impact forces is low. If the intercepted rockfall is not cleared away in time to allow the mesh to recover, it is very likely to break when it is hit by another rockfall.

[0025] In one embodiment of the present invention, the rolling stone protection mechanism also includes a third protection net, which includes a third net body, a second pull rope, a first pulley, a reinforcement ring, a third pull rope and a second pulley. The edge of the third net body is fixedly connected to the first net body through the second pull rope, the first pulley is mounted on the first fixed plate, the second pull rope is wound around the first pulley, the reinforcement ring is arranged on the third net body, the reinforcement ring includes an outer tube, an inner tube and a third spring, the inner tube is slidably arranged in the outer tube, the end of the inner tube is connected to the inner cavity end of the outer tube through the third spring, the second fixed plate is fixedly connected to the third net body through the third pull rope, the second pulley is mounted on the first fixed plate, and the third pull rope is wound around the second pulley.

[0026] By adopting the above scheme, the deformation of the first protective net is converted into the tensioning strength of the third net body in direct proportion through the second pull rope and the first pulley. The greater the deformation, the higher the tensioning strength. The third net body is given a certain degree of buffering protection and impact resistance through the reinforcing ring, which indirectly limits the deformation degree of the third net body and the first protective net, and extends the service life of the third net body and the first protective net. The deformation of the third net body is converted into the displacement of the second net body in direct proportion through the third pull rope and the second pulley. The impact resistance of the device is greatly improved in conjunction with the first protective net and the third net body. The first protective net and the second protective net are linked together through the third protective net, which realizes the comprehensive improvement of the hard protection capability and buffering protection capability of the device, and extends the service life of the net body while improving the protection strength.

[0027] In one embodiment of the present invention, the mesh diameter of the third mesh is set at 100mm-150mm. The mesh diameter of the third mesh is smaller than the mesh diameter of the first mesh, which can make up for the impact resistance of the mesh of the first mesh and cooperate with the first mesh to enhance the overall protection strength of the device.

[0046] Example

[0047] See also Figures 1-9 The present invention provides a technical solution: a soft and hard interlayer collapse protection structure includes a ground fixing mechanism 100 and a rolling stone protection mechanism 200. The rolling stone protection mechanism 200 is arranged on the ground fixing mechanism 100. The ground fixing mechanism 100 is used to fix the rolling stone protection mechanism 200 to the ground, and the rolling stone protection mechanism 200 is used to intercept rolling stones.

[0048] See also Figure 2 The ground fixing mechanism 100 includes a fixing frame 110 and a ground anchor assembly 120. The fixing frame 110 includes a bottom plate 111 and a side plate 112. The side plate 112 is fixed to the upper surface of the bottom plate 111. The fixing frame 110 also includes a reinforcing rib 113. The reinforcing rib 113 is fixed between the upper surface of the bottom plate 111 and the bottom of the side wall of the side plate 112, thereby strengthening the connection strength between the side plate 112 and the bottom plate 111 and improving the overall impact resistance of the fixing frame 110. The ground anchor assembly 120 is symmetrically arranged on the fixing frame 110 for firmly fixing the fixing frame 110 to the ground.

[0049] The extreme situations that protective nets face during use generally fall into two categories: the anchor mechanism detaching from the ground and the net breaking. Either of these situations will cause the net to lose its interception capability. The anchor mechanism detaching from the ground is primarily due to insufficient anchoring reliability. When the net is impacted, the anchor mechanism initially becomes skewed, and then, under further impact from the rockfall, it detaches from the anchor holes, rendering the net unable to directly intercept the rockfall and causing the device to lose its interception capability.

[0050] See also Figure 3 and Figure 4 , the ground anchor assembly 120 includes a first anchor 121 and a second anchor 122, the first anchor 121 includes an anchor rod 1211, a first resistance rod 1212, a first fixing frame 1213, a first slider 1214, a first fixing rod 1215 and an insertion rod 1216, the anchor rod 1211 is fixed to the base plate 111, the bottom end of the anchor rod 1211 is set to an inverted cone shape, which reduces the bottom force area and is convenient for anchoring into the ground, the side of the anchor rod 1211 is provided with a first opening 1217 and a second opening 1218, the first resistance rod 1212 is hinged in the first opening 1217, the first fixing frame 1213 is fixed to the side wall of the inner cavity of the anchor rod 1211, the first slider 1214 is slidably set on the first fixing frame 1213, the first fixing The two ends of the rod 1215 are respectively hinged to the first resistance rod 1212 and the first slider 1214, and the insertion rod 1216 is slidably connected to the inner cavity of the anchor rod 1211; during installation, the fixing frame 110 is first placed at the installation point, so that the anchor rod 1211 passes through the mounting hole on the base plate 111, and the anchor rod 1211 is anchored into the ground. The anchor rod 1211 and the base plate 111 are connected together by the locking piece, and then the insertion rod 1216 is slid into the anchor rod 1211. During the sliding process, the insertion rod 1216 will drive the first slider 1214 to move downward, and then drive the first resistance rod 1212 to rotate to an inclined state through the first fixing rod 1215, providing great resistance to the upward movement of the anchor rod 1211, and then the insertion rod 1216 and the anchor rod 1211 are connected together by the locking piece to complete the installation and fixation of the fixing frame 110.

[0051] See also Figure 3 、 Figure 5 and Figure 6 The second anchoring member 122 includes a second resistance rod 1221, a second fixing frame 1222, a second slider 1223, a second fixing rod 1224, a first pull rope 1225 and a second spring 1226. A third opening 1219 is opened on the side of the insertion rod 1216. The second resistance rod 1221 is hinged in the third opening 1219. The second fixing frame 1222 is fixed to the side wall of the inner cavity of the insertion rod 1216. The second slider 1223 is slidably set on the second fixing frame 1222. The two ends of the second fixing rod 1224 are respectively hinged to the second resistance rod 1221 and the second slider 1223. The upper surface of the second slider 1223 is hinged to the first pull rope 1225. The rope 1225 is fixedly connected to the first net body 212 and the second net body 222, and the two ends of the second spring 1226 are respectively fixedly connected to the lower surface of the second slider 1223 and the bottom of the inner cavity of the insertion rod 1216; when the rolling stone hits the first protective net 210 or the second protective net 220, the deformation of the net body will drive the second slider 1223 to move upward through the first pull rope 1225, and then drive the second resistance rod 1221 to rotate to an inclined state through the second fixed rod 1224, further enhancing the resistance to the upward movement of the anchor rod 1211, and setting the lower surface of the second slider 1223 to the bottom of the inner cavity of the insertion rod 1216 through the second spring 1226, giving the net body a certain degree of buffering and protection capability.

[0052] By adopting the above scheme, the deformation of the first protective net 210 is converted into the anchoring strength of the anchor rod 1211 in direct proportion through the second anchor 122. The greater the deformation, the more secure the anchoring. The first protective net 210 is given a certain degree of buffering protection capability through the second spring 1226. In conjunction with the first anchor 121, the overall anchoring reliability and impact resistance of the ground fixing mechanism 100 are effectively improved, which can prevent the ground fixing mechanism 100 from detaching from the ground when the net body is hit by rolling stones, thereby ensuring the normal interception of rolling stones by the device.

[0053] It should be specifically explained that the first pull rope 1225 includes a first connecting rope 12251 and a second connecting rope 12252. The bottom end of the first connecting rope 12251 is fixed to the upper surface of the second slider 1223, and the top end of the first connecting rope 12251 is fixedly connected to the first net body 212 and the second net body 222 through the second connecting rope 12252. The top and bottom ends of the channel in the insertion rod 1216 for the first connecting rope 12251 to pass through are both set to chamfered corners, which reduces the friction resistance of the first connecting rope when sliding and reduces the wear and tear of the first connecting rope during use.

[0054] The existing stake-type protection nets lack temporary remedial measures. When the net is damaged due to excessive impact force, the protection net loses its ability to intercept rolling stones and can no longer ensure the safety of the area before the net is replaced or repaired.

[0055] See also Figure 2 and Figure 7 , the rolling stone protection mechanism 200 includes a first protection net 210 and a second protection net 220, the first protection net 210 is connected to the two fixing frames 110 on both sides, the first protection net 210 includes a first fixing plate 211 and a first net body 212, the bottom and top of the first fixing plate 211 are fixedly connected to the upper surface of the bottom plate 111 and the top of the side plate 112 respectively, the edge of the first net body 212 is fixedly connected to one side of the first fixing plate 211, at least two first fixing plates 211 are provided, the structures and sizes of the two first fixing plates 211 are exactly the same, the first net body 212 is fixed between the two first fixing plates 211, the mesh diameter of the first net body 212 is set at 150mm-250mm, the second protection net 220 is connected to the two fixing frames on both sides respectively 110 is connected, the second protective net 220 includes a second fixing plate 221, a second mesh body 222 and a connecting piece 223, one side of the second fixing plate 221 is connected to the side plate 112 through the connecting piece 223, the edge of the second mesh body 222 is fixedly connected to the second fixing plate 221, at least two second fixing plates 221 are provided, and the two second fixing plates 221 have exactly the same structure and size, the second mesh body 222 is fixed between the two second fixing plates 221, the mesh diameter of the second mesh body 222 is set at 50mm-100mm, and the mesh diameter of the second mesh body 222 is smaller than the mesh diameter of the first mesh body 212, so that small-volume gravel passing through the first mesh body 212 can be intercepted; by arranging the second mesh body 222 behind the first mesh body 212, small-volume gravel passing through the first mesh body 212 can be intercepted, and when the first mesh body 212 is damaged, it can play a backup interception role, continue to ensure regional safety, and reserve sufficient time for the maintenance and replacement of the first mesh body 212.

[0056] It should be specifically explained that the connecting member 223 includes a sleeve 2231, a first spring 2232 and a sliding rod 2233. The sleeve 2231 is fixed on the side plate 112. One end of the sliding rod 2233 is connected to the inner wall of the sleeve 2231 through the first spring 2232. The other end of the sliding rod 2233 is fixedly connected to one side of the second fixed plate 221, so that the second fixed plate 221 is elastically slidably connected to the side plate 112, thereby improving the overall buffering and protection capability of the second protective net 220, and also allowing the second net body 222 to automatically reset after cleaning the rolling stones.

[0057] The mesh breaks because the impact force of the rockfall exceeds the upper limit of the mesh's protective capacity. Existing protective nets are generally used alone. When the net's rigid protection is high but its buffering capacity is low, the net's initial protection is strong, it can withstand high direct impact forces, and can quickly intercept rockfalls. However, each impact significantly reduces the durability of the mesh's braided ropes, resulting in a short mesh lifespan and a rapid decline in protective capacity. When the net's buffering capacity is strong but its rigid protection is too low, the mesh deforms significantly under impact, and its ability to withstand direct impact forces is low. If the intercepted rockfall is not cleared away in time to allow the mesh to recover, it is very likely to break when it is hit by another rockfall.

[0058] See also Figure 2 、 Figure 8 and Figure 9, the rolling stone protection mechanism 200 also includes a third protection net 230, the third protection net 230 includes a third net body 231, a second pull rope 232, a first pulley 233, a reinforcement ring 234, a third pull rope 235 and a second pulley 236, the edge of the third net body 231 is fixedly connected to the first net body 212 through the second pull rope 232, the first pulley 233 is installed on the first fixed plate 211, the second pull rope 232 is wound around the first pulley 233, the reinforcement ring 234 is passed through the third net body 231, the reinforcement ring 234 includes an outer tube 2341, an inner tube 2342 and a third spring 2343, the inner tube 2342 is slidably arranged in the outer tube 2341, the end of the inner tube 2342 is connected to the inner cavity end of the outer tube 2341 through the third spring 2343, the second fixed plate 221 is connected to the outer tube 2341 through the third pull rope 23 5 is fixedly connected to the third net body 231, the second pulley 236 is installed on the first fixing plate 211, and the third pull rope 235 is wound around the second pulley 236; when the first protective net 210 is deformed by impact, the third net body 231 will be tensioned under the action of the second pull rope 232 and the first pulley 233, and cooperate with the first protective net 210 to intercept rolling stones. The reinforcement ring 234 provided on the third net body 231 can not only provide buffering capacity for the third net body 231 through its own elastic expansion, but also limit the deformation of the third net body 231 within a certain range, further enhancing the impact resistance of the third net body 231, thereby preventing damage to the third net body 231 and extending its service life. When the third net body 231 is deformed by impact, the second net body 222 will move toward the third net body 231 under the action of the third pull rope 235 and the second pulley 236, further improving the interception capability of the device.

[0059] By adopting the above scheme, the deformation of the first protective net 210 is converted into the tensioning strength of the third net body 231 in direct proportion through the second pull rope 232 and the first pulley 233. The greater the deformation, the higher the tensioning strength. The third net body 231 is given a certain degree of buffering protection and impact resistance through the reinforcing ring 234, which indirectly limits the deformation degree of the third net body 231 and the first protective net 210, and extends the service life of the third net body 231 and the first protective net 210. The deformation of the third net body 231 is converted into the displacement of the second net body 222 in direct proportion through the third pull rope 235 and the second pulley 236. In conjunction with the first protective net 210 and the third net body 231, the impact resistance of the device is greatly improved. The first protective net 210 and the second protective net 220 are linked together through the third protective net 230, thereby achieving a comprehensive improvement in the hard protection capability and buffering protection capability of the device, while improving the protection strength and extending the service life of the net body.

[0060] It should be specifically noted that the mesh diameter of the third mesh body 231 is set at 100mm-150mm. The mesh diameter of the third mesh body 231 is smaller than the mesh diameter of the first mesh body 212, which can make up for the impact resistance of the mesh of the first mesh body 212 and cooperate with the first mesh body 212 to enhance the overall protection strength of the device.

[0061] Specifically, the working principle of the soft-hard interlayer collapse protection structure is as follows: when in use, first place the fixing frame 110 on the installation point, pass the anchor rod 1211 through the installation hole on the base plate 111, anchor the anchor rod 1211 into the ground, connect the anchor rod 1211 and the base plate 111 together through the locking piece, and then slide the insertion rod 1216 into the anchor rod 1211. The insertion rod 1216 will drive the first slider 1214 to move downward during the sliding process, and then drive the first resistance rod 1212 to rotate to an inclined state through the first fixing rod 1215, providing great resistance to the upward movement of the anchor rod 1211, and then connect the insertion rod 1216 and the anchor rod 1211 together through the locking piece. The installation and fixation of the fixing frame 110 is completed. When the first net body 212 is deformed by impact, the third net body 231 will be tensioned under the action of the second pull rope 232 and the first pulley 233, and cooperate with the first net body 212 to intercept the rolling stones. The reinforcement ring 234 set on the third net body 231 can provide buffering capacity for the third net body 231 through its own elastic expansion, and can also limit the deformation of the third net body 231 within a certain range. When the third net body 231 is deformed by impact, the second net body 222 will move toward the third net body 231 under the action of the third pull rope 235 and the second pulley 236, further improving the interception ability of the device.
