Description

Technical Field

[0001] The present invention belongs to the technical field of highway engineering, and particularly relates to a slope protection net support for highway engineering. Background Art

[0002] Many highways are generally close to mountains with relatively high slopes. A layer of slope protection net is installed on the side of the mountain close to the highway to prevent crushed stones from rolling down. Otherwise, the rolling rocks will pose a serious safety hazard to passing vehicles. To improve the stability of the slope protection net when installed on the slope, several support members usually need to be installed on the slope, and the overall installation of the slope protection net is achieved through the support members.

[0003] In the prior art, the slope protection net support members are generally vertically inserted and installed on the slope, and then the slope protection net is installed between the respective slope protection net support members. The installation of the slope protection net on the slope is achieved through the use of the respective slope protection net support members.

[0004] Since the slope protection net support members are vertically inserted on the slope, the water flow along the slope during rainy days will scour the slope protection net support members, which is likely to cause the slope protection net support members to become loose and continue to tilt downward. As a result, the slope protection net may deviate from the slope surface, ultimately leading to a significant reduction in the slope protection effect. For this reason, we provide a slope protection net support for highway engineering to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a slope protection net support for highway engineering. Through the specific structural design of the outer support component, the inner support component, and the energy dissipation and diversion component, the problems in the prior art are solved. Since the slope protection net support members are vertically inserted on the slope, the water flow along the slope during rainy days will scour the slope protection net support members, which is likely to cause the slope protection net support members to become loose and continue to tilt downward. As a result, the slope protection net may deviate from the slope surface, ultimately leading to a significant reduction in the slope protection effect.

[0013] The present invention is further configured such that an extension ring base is fixedly provided on the circumferential side surface of the hollow diversion portion, an L-shaped support bracket is fixedly provided on the circumferential side surface of the extension ring base, an installation ring sleeving on the top of the outer support rod is fixedly provided at the bottom of the extension ring base, the installation ring and the outer support rod are connected by a fastener, a central diversion cavity and a second diversion cavity are arranged inside the hollow diversion portion, the hollow on-off member is slidably fitted inside the central diversion cavity, an energy-dissipating diversion pipe communicated with the second diversion cavity is installed on the circumferential side surface of the hollow diversion portion, the first diversion cavity and the central diversion cavity are communicated through a second water inlet, the second diversion cavity and the central diversion cavity are communicated through a second water outlet; a third axial hole communicated with the central diversion cavity is opened at the top of the hollow diversion portion, the retraction tension rod is slidably fitted with the third axial hole, a fourth axial hole communicated with the central diversion cavity is opened at the bottom of the hollow diversion portion, the diameter of the fourth axial hole is the same as that of the central diversion cavity, a connection disk is fixedly provided inside the energy-dissipating diversion pipe, one end of a moving rod slidably arranged on the connection disk is fixed with a piston disk, the other end of the moving rod is fixedly provided with an energy-dissipating reaction support portion, the arc-shaped support plate is rotatably arranged on the top of the extension ring base, and the cleaning member is slidably attached to the circumferential side surface of the hollow diversion portion.

[0014] The present invention has the following beneficial effects: 1. When rainwater flows down along the slope in the present invention, the flowing water enters the first diversion cavity after being filtered by the filter structure. The rainwater entering the first diversion cavity sequentially passes through the second through-flow port, the third through-flow port and the first through-flow port and flows into the corresponding axial water storage cavity, so that the axial water storage cavity is gradually filled with rainwater, increasing the weight of the axial water storage cavity. Therefore, the gravity imbalance tube rotates due to gravity imbalance. When the gravity imbalance tube rotates, it drives the first transmission ring to rotate. Under the cooperation of the guiding member fixed on the inner wall of the first transmission ring and the spiral groove on the axial transmission portion, the axial transmission portion is driven to gradually move downward, and then drives the retraction tension rod to move towards the inner side of the outer support rod (i.e., towards the direction close to the slope). Thus, the slope protection net can be closely attached to the slope, which can greatly reduce the influence of rainwater scouring on the slope protection net on the slope, so as to ensure the protection effect of the slope protection net on the slope beside the road on rainy days.

[0015] During the process of the retractable tension rod moving towards the inner side of the outer support rod, the first water inlet and the second water inlet on the hollow closing member are gradually connected, and at the same time, the first water outlet and the second water outlet on the hollow closing member are gradually connected. Part of the rainwater that enters the first diversion cavity after being filtered by the filter structure enters the corresponding axial water storage cavity, and the other part of the rainwater first enters the central diversion cavity and the hollow closing member through the second water inlet and the first water inlet, and then flows downward into the energy-dissipating diversion pipe through the first water outlet and the second water outlet. The rainwater entering the energy-dissipating diversion pipe acts on the piston disk and pushes it downward. Under the action of the moving rod, the energy-dissipating anti-support part is driven to move downward until it tightly presses against the L-shaped support bracket on another energy-dissipating diversion component below it. The reaction force of the L-shaped support bracket on the energy-dissipating anti-support part is used to support the entire slope protection net support above, which can greatly weaken the impact of rainwater scouring on each slope protection net support, so that each slope protection net support will not be loosened significantly, thereby effectively improving the stable layout of the entire slope protection net on the slope beside the road.

[0016] During the process of the axial transmission part gradually moving downward, each conical transmission part that moves synchronously with the axial transmission part drives each limit guide part to slide along the corresponding inclined channel, and then drives each impact buffer part to slide radially along the corresponding arc-shaped supporting part, so that each impact buffer part passes through the radial through-hole and inserts into the slope soil layer. Then, the reaction force of the L-shaped support bracket on the energy-dissipating anti-support part is used to support the entire slope protection net support above. Thus, the stable installation of each slope protection net support on the slope can be greatly increased, and the influence of rainwater scouring on the slope protection net and its support parts can be effectively weakened.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] For the first specific embodiment, please refer to Figure 1-17, the present invention is a slope protection net support member for highway engineering. The slope protection net support member is installed on a slope and arranged perpendicular to the slope, and a slope protection net is installed between each slope protection net support member; wherein, the slope protection net support member includes an outer support assembly 1, an inner support assembly 2 and an energy dissipation and diversion assembly 3. The inner support assembly 2 is rotatably installed on the outer support assembly 1 and the two are coaxially arranged. The energy dissipation and diversion assembly 3 is installed on the top of the outer support assembly 1 and the two are coaxially arranged; the outer support assembly 1 includes a gravity imbalance cavity 101, the inner support assembly 2 includes a first through-flow port 201 and a gravity imbalance tube 202 rotatably arranged inside the gravity imbalance cavity 101. A plurality of axial water storage cavities 203 are circumferentially arranged inside the gravity imbalance tube 202. The first through-flow port 201 is communicated with the corresponding axial water storage cavity 203. An axially movable retraction and tension rod 204 is arranged outside the gravity imbalance cavity 101 (it should be noted that the position of the first through-flow port 201 is aligned with an axial water storage cavity 203, and when rainwater enters the axial water storage cavity 203 and causes the gravity imbalance of the gravity imbalance tube 202, the rotation direction of the gravity imbalance tube 202 can drive the retraction and tension rod 204 to move towards the slope), and a net fixing part (not shown in the figure) for installing the slope protection net is arranged at the top of the retraction and tension rod 204; the energy dissipation and diversion assembly 3 includes a hollow diversion part 301. A first diversion cavity 302 is arranged inside the hollow diversion part 301. A filter structure 303 communicated with the first diversion cavity 302 is arranged on the circumferential side surface of the hollow diversion part 301. The first diversion cavity 302 is communicated with the first through-flow port 201 through a second through-flow port 304. When the gravity imbalance tube 202 rotates due to water inflow and drives the retraction and tension rod 204 to retract and move, the slope protection net is closely attached to the slope through each retraction and tension rod 204.

[0039] In this embodiment of the present invention, the outer support assembly 1 further includes an outer support rod 102 vertically inserted into the slope. A partition plate 103 is fixedly arranged inside the outer support rod 102. The gravity imbalance cavity 101 is arranged above the partition plate 103. An impact buffer cavity 104 is arranged below the partition plate 103. A first axial hole 105 for communicating the gravity imbalance cavity 101 and the impact buffer cavity 104 is arranged on the surface of the partition plate 103. A second axial hole 106 and a third through-flow port 107 communicated with the gravity imbalance cavity 101 are arranged at the top of the outer support rod 102. The third through-flow port 107 is communicated with the second through-flow port 304 and the first through-flow port 201 on its upper and lower sides.

[0040] In this embodiment of the present invention, the inner support assembly 2 further includes a hollow inner support column 205, which is coaxially and fixedly installed inside the gravity imbalance cavity 101. The first through-flow port 201 is opened at the top of the hollow inner support column 205 and is communicated with its inner cavity. An annular support seat is rotatably installed inside the hollow inner support column 205. The gravity imbalance tube 202 is fixedly installed on the annular support seat. An annular water storage cavity is provided inside the gravity imbalance tube 202. The top of the annular water storage cavity is an open structure. The annular water storage cavity is divided into a plurality of axial water storage cavities 203 by a plurality of axial partition plates 206.

[0041] A first transmission ring 207 coaxial with it is fixedly installed on the inner wall of the annular support seat. An axial transmission part 208 is slidably sleeved inside the first transmission ring 207. A spiral channel is opened on the circumferential side of the axial transmission part 208. The guiding member fixed on the inner wall of the first transmission ring 207 is slidably fitted inside the spiral channel on the axial transmission part 208. A first support rod 209 axially slidably fitted with the hollow inner support column 205 is fixedly provided at the top of the axial transmission part 208. The top of the first support rod 209 penetrates through the second axial hole 106.

[0042] According to the specific situation of the slope beside the road, a certain number of slope protection net support members are vertically inserted and installed on the slope, and then the slope protection net is installed and fixed on the net fixing parts of each slope protection net support member. In this way, the installation and layout of the slope protection net on the slope are realized. When it rains, the rainwater flows down along the slope. The flowing water enters the first diversion cavity 302 after being filtered by the filter screen structure 303. The rainwater entering the first diversion cavity 302 sequentially passes through the second through-flow port 304, the third through-flow port 107 and the first through-flow port 201 and flows into the corresponding axial water storage cavity 203. As a result, the axial water storage cavity 203 is gradually filled with rainwater, increasing its weight. Therefore, the gravity imbalance tube 202 rotates due to gravity imbalance. When the gravity imbalance tube 202 rotates, it drives the first transmission ring 207 to rotate. Under the cooperation of the guiding member fixed on the inner wall of the first transmission ring 207 and the spiral channel on the axial transmission part 208, the axial transmission part 208 is driven to gradually move downward, and then drives the retraction tension rod 204 to move towards the inner side of the outer support rod 102 (i.e., towards the direction close to the slope). Thus, the slope protection net can be tightly attached to the slope, greatly reducing the impact of rainwater scouring on the slope protection net beside the road, and ensuring the protection effect of the slope protection net on the slope beside the road in rainy days.

[0043] Specific Embodiment 2. On the basis of Specific Embodiment 1, radial through-ports 108 communicating with the impact buffer cavity 104 are arranged in a circumferential array on the circumferential side surface of the outer support rod 102. A guiding channel 109 coaxial with it is opened at the bottom of the impact buffer cavity 104. Arc-shaped supporting parts 110 corresponding to the radial through-ports 108 one by one are fixedly installed on the inner wall of the impact buffer cavity 104. The arc-shaped supporting parts 110 are arranged coaxially with the corresponding radial through-ports 108.

[0044] At the bottom of the axial transmission part 208, a second support rod 210 that axially slides with the hollow inner support column 205 is fixedly arranged. The second support rod 210 slides with the first axial hole 105. A conical transmission part 211 located inside the impact buffer cavity 104 is fixedly installed on the circumferential side surface of the second support rod 210. Oblique channels 212 corresponding to the radial through-ports 108 one by one are opened on the circumferential side surface of the conical transmission part 211. An impact buffer part 213 is slidably arranged inside the arc-shaped supporting part 110. A limiting guide part 214 slidably connected with the oblique channel 212 is fixedly arranged at the end of the impact buffer part 213. By arranging a plurality of impact buffer parts 213 circumferentially and making the impact buffer parts 213 fit inside the corresponding arc-shaped supporting parts 110, it can be ensured that each impact buffer part 213 can only slide radially along the corresponding arc-shaped supporting part 110. At the same time, through the sliding cooperation between the limiting guide part 214 and the corresponding oblique channel 212, it can be ensured that only the radial movement of each limiting guide part 214 can be driven during the up and down movement of the conical transmission part 211. Thus, it can be ensured that the circumferentially arranged impact buffer parts 213 move radially synchronously. At the bottom of the second support rod 210, a guiding disk 215 slidably fitted inside the guiding channel 109 is fixedly arranged. Since the guiding disk 215 is fitted inside the guiding channel 109 and the guiding channel 109 is arranged coaxially with the outer support rod 102, it can be ensured that the axial transmission part 208 on the second support rod 210 can only move up and down along the axis.

[0045] In this embodiment of the present invention, a hollow opening and closing member 216 is fixedly installed at the top of the first support rod 209. The outer diameter of the hollow opening and closing member 216 is the same as the diameter of the second axial hole 106. The retraction tension rod 204 is fixedly installed at the top of the hollow opening and closing member 216. A spiral groove is provided on the circumferential side surface of the retraction tension rod 204. A second transmission ring 217 is sleeved on the retraction tension rod 204. A guiding member fixed to the inner wall of the second transmission ring 217 is slidably fitted inside the spiral groove on the retraction tension rod 204. Through this structural design, when the first support rod 209 moves synchronously with the axial transmission part 208, the hollow opening and closing member 216 moves synchronously with the first support rod 209, thereby driving the retraction tension rod 204 to move synchronously. Under the cooperation of the guiding member fixed to the inner wall of the second transmission ring 217 and the spiral groove on the retraction tension rod 204, the second transmission ring 217 is driven to rotate. A support ring 218 coaxial with the second transmission ring 217 is sleeved outside the second transmission ring 217. The support ring 218 and the second transmission ring 217 are connected by a radial fixing member. A cleaning member 219 and an arc-shaped support plate 220 are respectively fixedly arranged at the bottom of the support ring 218. While the second transmission ring 217 rotates, it drives the support ring 218 to rotate synchronously, thereby driving the cleaning member 219 to slide along the outer wall of the hollow diversion part 301. Thus, the sundries accumulated at the position of the filter structure 303 can be removed by the cleaning member 219, which is beneficial for rainwater to enter the first diversion cavity 302 through the filter structure 303. First water inlets 221 and first water outlets 222 are respectively provided on the circumferential side surface of the hollow opening and closing member 216.

[0046] In this embodiment of the present invention, an extension ring base 305 is fixedly arranged on the circumferential side surface of the hollow diversion part 301 (after installation, the extension ring base 305 is closely attached to the slope surface beside the road). An L-shaped support bracket 306 is fixedly arranged on the circumferential side surface of the extension ring base 305. An installation ring 307 sleeving the top of the outer support rod 102 is fixedly arranged at the bottom of the extension ring base 305. The installation ring 307 and the outer support rod 102 are connected by fasteners. A central diversion cavity 308 and a second diversion cavity 309 are arranged inside the hollow diversion part 301. The hollow closing member 216 is slidably fitted inside the central diversion cavity 308. An energy-dissipating diversion pipe 310 communicating with the second diversion cavity 309 is installed on the circumferential side surface of the hollow diversion part 301. The first diversion cavity 302 and the central diversion cavity 308 are communicated through a second water inlet 311. The second diversion cavity 309 and the central diversion cavity 308 are communicated through a second water outlet 312. At the initial state, the top of the hollow closing member 216 is fitted to the top of the central diversion cavity 308. At this time, the first water inlet 221 on the hollow closing member 216 is misaligned with the second water inlet 311, and the first water outlet 222 on the hollow closing member 216 is also misaligned with the second water outlet 312. Thus, the rainwater entering the first diversion cavity 302 through the filter structure 303 can only sequentially pass through the second through-flow port 304, the third through-flow port 107, and the first through-flow port 201 and flow into the corresponding axial water storage cavity 203. Then, the axial water storage cavity 203 gradually fills with rainwater, increasing the weight of the axial water storage cavity 203. Therefore, the gravity imbalance tube 202 rotates due to gravity imbalance. When the gravity imbalance tube 202 rotates, it drives the first transmission ring 207 to rotate. Under the cooperation of the guiding member fixed on the inner wall of the first transmission ring 207 and the spiral groove on the axial transmission part 208, the axial transmission part 208 is driven to gradually move downward, and then the retraction and tension rod 204 is driven to move towards the inner side of the outer support rod 102 (i.e., towards the direction close to the slope). Thus, the slope protection net can be closely attached to the slope.

[0047] A third axial hole 313 communicating with the central diversion cavity 308 is opened at the top of the hollow diversion part 301. The retraction and tension rod 204 is slidably fitted with the third axial hole 313. A fourth axial hole 314 communicating with the central diversion cavity 308 is opened at the bottom of the hollow diversion part 301. The diameter of the fourth axial hole 314 is the same as that of the central diversion cavity 308. A connection disk 315 is fixedly arranged inside the energy-dissipating diversion pipe 310. One end of a moving rod 316 slidably arranged on the connection disk 315 is fixed with a piston disk 317, and the other end of the moving rod 316 is fixedly provided with an energy-dissipating anti-support part 318. The arc-shaped support plate 220 is rotatably arranged on the top of the extension ring base 305. The cleaning member 219 is slidably attached to the circumferential side surface of the hollow diversion part 301.

[0048] When rainwater flows down along the slope on a rainy day, the flowing water enters the interior of the first diversion cavity 302 after being filtered by the filter screen structure 303. The rainwater that enters the first diversion cavity 302 successively passes through the second through-flow port 304, the third through-flow port 107, and the first through-flow port 201 and flows into the corresponding axial water storage cavity 203. As a result, the axial water storage cavity 203 gradually fills with rainwater, increasing the weight of the axial water storage cavity 203. Therefore, the gravity imbalance tube 202 rotates due to gravity imbalance. When the gravity imbalance tube 202 rotates, it drives the first transmission ring 207 to rotate. Under the cooperation of the guiding member fixed to the inner wall of the first transmission ring 207 and the spiral channel on the axial transmission portion 208, the axial transmission portion 208 is driven to gradually move downward, and then the retracting and tensioning rod 204 is driven to move in the direction of the inner side of the outer strut 102 (i.e., move closer to the slope). Thus, the slope protection net can be closely attached to the slope.

[0049] During the process of the retractable tension rod 204 moving towards the inner side of the outrigger 102, the first water inlet 221 on the hollow opening and closing member 216 gradually communicates with the second water inlet 311, and at the same time, the first water outlet 222 on the hollow opening and closing member 216 gradually communicates with the second water outlet 312. Part of the rainwater that enters the first diversion cavity 302 after being filtered by the filter structure 303 enters the corresponding axial water storage cavity 203, and the other part of the rainwater first enters the central diversion cavity 308 and the hollow opening and closing member 216 through the second water inlet 311 and the first water inlet 221, and then flows downward into the energy-dissipating diversion pipe 310 through the first water outlet 222 and the second water outlet 312. The rainwater that enters the energy-dissipating diversion pipe 310 acts on the piston disk 317 and pushes it downward. Under the action of the moving rod 316, the energy-dissipating anti-support part 318 is driven to move downward until it tightly presses against the L-shaped support bracket 306 on another energy-dissipating diversion assembly 3 below it. The support for the entire slope protection net support member above is achieved by using the reaction force of the L-shaped support bracket 306 on the energy-dissipating anti-support part 318 (it is also possible that after installing each slope protection net support member, the energy-dissipating anti-support part 318 is closely attached to the L-shaped support bracket 306 below it due to its own weight. Subsequently, the rainwater in the energy-dissipating diversion pipe 310 acts on the piston disk 317 and generates a downward movement trend. Similarly, the support for the entire slope protection net support member above is achieved by using the reaction force of the L-shaped support bracket 306 on the energy-dissipating anti-support part 318). At the same time, during the gradual downward movement of the axial transmission part 208, each conical transmission member 211 that moves synchronously with the axial transmission part 208 drives each limit guide member 214 to slide along the corresponding inclined channel 212, and then drives each impact buffer member 213 to perform a radial slide along the corresponding arc-shaped supporting part 110, so that each impact buffer member 213 passes through the radial through-port 108 and inserts into the slope soil layer. Thus, through the mutual support between each slope protection net support member on the slope, the impact of rainwater scouring on each slope protection net support member can be greatly weakened (at the same time, the loosening caused by the settlement of the entire support member along the slope due to the self-weight of the inclined slope protection net support member can be reduced), so that each slope protection net support member will not loosen significantly, and thus the stable layout of the entire slope protection net on the slope beside the road can be effectively improved.
