Description

Technical Field

[0001] This application relates to the field of dam construction and maintenance, and in particular to a dam face slope stabilization device. Background Technology

[0002] Currently, in the construction and maintenance of hydraulic structures, especially reservoir dams, slope stability is one of the key factors ensuring the safety of the entire project. Traditional slope reinforcement methods mainly include vegetation slope protection, masonry slope protection, and shotcrete slope protection with anchor bolts. These methods each have their advantages but also obvious limitations. With the advancement of technology and the growth of social needs, how to effectively improve the stability and durability of slopes has become a research hotspot. In recent years, the most common slope stabilization method is concrete slope stabilization, which involves laying concrete on the slope surface for stabilization.

[0003] During the process of concrete slope stabilization, it is necessary to flatten and compact the concrete on the slope surface. However, since the dam slope is mostly inclined, traditional processing equipment is not convenient for slope construction, while manual construction is difficult and time-consuming. Therefore, there is an urgent need for an automated slope stabilization equipment that can shorten the construction cycle. Summary of the Invention

[0004] To address the issue of long construction cycles for dam slope stabilization, this application provides a dam slope stabilization device.

[0005] The dam slope stabilization device provided in this application adopts the following technical solution:

[0006] A slope stabilization device for dam surfaces, comprising:

[0007] Slope stabilization components are used to install on the slope of a dam.

[0008] A drive component, connected to the slope stabilization component, is used to drive the slope stabilization component to move back and forth along the dam slope, thereby compacting the dam slope.

[0009] By adopting the above scheme, the drive component can drive the slope stabilization component to compact the concrete on the dam slope, thereby achieving automated slope stabilization and shortening the construction cycle.

[0010] Optionally, the slope stabilization component includes:

[0011] frame.

[0012] The compaction wheel is rotatably connected to the frame and is used to compact the dam slope.

[0013] By adopting the above method, the rolling roller can compact the dam slope by rolling, thereby stabilizing the slope while reducing damage to the dam slope.

[0014] Optionally, the slope stabilization assembly further includes a vibrating element disposed on the compaction wheel.

[0015] By adopting the above scheme, the roller can vibrate while rolling the dam slope, which facilitates the compaction and compaction of the concrete on the dam slope.

[0016] Optionally, the vibrating element vibrates when the rolling wheel moves toward the top of the dam slope.

[0017] When the rolling wheel moves toward the bottom of the dam slope, the vibrating element does not vibrate.

[0018] By adopting the above scheme, the roller vibrates only when going uphill, so that the sand and gravel that are shaken off can be compacted by the roller, thus preventing sand and gravel landslides.

[0019] Optionally, the dam slope stabilization device also includes a status detection component and a control module.

[0020] The status detection device is used to detect the movement status of the slope stabilization component, and both the status detection device and the vibration device are signal-connected to the control module.

[0021] By adopting the above scheme, the control module can determine whether the slope stabilization component is in an uphill or downhill state based on the detection data of the status detection device, so as to control the vibration device to turn on or off.

[0022] Optionally, the slope stabilization component further includes a first trimming component and a second trimming component.

[0023] The first trimming component is connected to the frame and is located on the side of the rolling wheel near the bottom of the dam slope.

[0024] The second trimming component is connected to the frame and is located on the side of the rolling wheel near the top of the dam slope.

[0025] Both the first trimming component and the second trimming component are used to trim the slope of the dam surface.

[0026] By adopting the above scheme, the first and second trimming components can trim the slope of the dam surface and improve the quality of slope stabilization.

[0027] Optionally, the center of gravity of the slope stabilization component is located on the side of the compaction wheel near the bottom of the dam slope.

[0028] The slope stabilization component also includes an adjustment unit.

[0029] The adjustment unit is located on the frame and is connected to the first trimming component. The adjustment unit is used to drive the first trimming component to move closer to or away from the dam slope, thereby switching the slope stabilization component between the first state, the second state, and the third state.

[0030] In the first state, the rolling wheel abuts against the dam slope, and both the first trimming part and the second trimming part are detached from the dam slope.

[0031] In the second state, both the rolling wheel and the first trimming component are in contact with the dam slope, and the second trimming component is disengaged.

[0032] In the third state, the rolling wheel, the first trimmer, and the second trimmer all abut against the dam slope.

[0033] By adopting the above scheme, the slope stabilization components can be adjusted to different states, thereby achieving different slope stabilization effects.

[0034] Optionally, the first trimming component includes a straight section and a gradient section. The length of the straight section is greater than the length of the rolling wheel. The gradient section is smoothly connected to both ends of the straight section. The distance between the gradient section and the dam slope gradually increases in the direction away from the straight section.

[0035] By adopting the above solution, the straight section of the first trimming component can eliminate the indentations left by the compaction wheel and / or compact uncompacted sand and gravel, further improving the slope stabilization quality. The straight section and the gradient section transition smoothly, avoiding leaving indentations on the concrete.

[0036] Optionally, the drive assembly includes a mobile base, a winch, a transition piece, a guide wheel, and a rope.

[0037] The winch is mounted on the mobile base and is connected to the slope stabilization assembly via the rope.

[0038] The transition piece has a guide portion for connecting the top of the movable base and the top of the dam slope.

[0039] The guide wheel is mounted on the movable base or the transition piece, and the guide wheel is used to guide the rope.

[0040] By adopting the above solution, the slope stabilization components can be easily moved. After stabilization is completed, the slope stabilization components can be moved to the top of the mobile base via the guide section for recycling and transfer.

[0041] Optionally, the transition member is connected to the movable base, and the transition member has a movable part.

[0042] The transition piece is also used to support the slope stabilization component.

[0043] By adopting the above scheme, the transition component can move with the moving base, so as to quickly move the slope stabilization component to other areas of the dam slope for slope stabilization work, thus shortening the construction cycle.

[0044] This application uses a drive component to move a slope stabilization component placed on the dam slope, thereby causing the slope stabilization component to roll back and forth on the dam slope, compacting the concrete and thus achieving automated slope stabilization of the dam slope, solving the problem of long construction cycle for dam slope stabilization.

[0051] The following is in conjunction with the appendix Figures 1 to 3 This application will be described in further detail.

[0052] like Figure 1 and Figure 2 As shown in the embodiment of this application, a dam slope stabilization device is disclosed, including a slope stabilization component 1 and a driving component 2. The slope stabilization component 1 is used to be installed on the dam slope; the driving component 2 is connected to the slope stabilization component 1 and is used to drive the slope stabilization component 1 to move back and forth along the dam slope, thereby compacting the dam slope.

[0053] Specifically, the slope stabilization assembly 1 includes a frame 11 and a compaction wheel 12. The frame 11 may be made of high-strength steel to ensure its durability and stability in harsh environments. Lifting lugs may be provided on the frame 11 to facilitate the movement of the slope stabilization assembly 1 by a lifting device.

[0054] The compaction roller 12 is rotatably connected to the frame 11 and is used to compact the dam surface slope. The compaction roller 12 can be made of a variety of materials, such as steel or high abrasion-resistant rubber. Steel has high strength and density, resulting in good compaction effect; while high abrasion-resistant rubber has better resistance to chemical corrosion.

[0055] like Figure 1 and Figure 2 As shown, the drive assembly 2 is connected to the frame 11 and drives the frame 11 and the compaction wheel 12 to move back and forth between the top and bottom of the dam slope, so that the compaction wheel 12 rolls back and forth on the dam slope, thereby compacting the concrete on the dam slope.

[0056] The drive assembly 2 includes a movable base 21, a winch 22, a transition piece 23, a guide wheel 24, and a rope 25.

[0057] The mobile base 21 is located on the ground surface at the top of the dam slope. The mobile base 21 can be an engineering vehicle or a mounting frame that can be moved by mobile equipment such as engineering vehicles.

[0058] The winch 22 is mounted on the mobile base 21 and is connected to the frame 11 via a rope 25. When the winch 22 releases the rope 25, the rolling wheel 12 rolls gradually down the slope of the dam under the action of gravity, thus making the entire slope stabilization component 1 move downhill. Conversely, when the winch 22 gradually retracts the rope 25, the rolling wheel 12 rolls gradually up the slope under the action of tension, thus making the entire slope stabilization component 1 move uphill.

[0059] The transition piece 23 is located on the side of the mobile base 21 near the dam slope and is connected to the mobile base 21. The transition piece 23 has a guide part 231, which can be an inclined surface. The higher end of the inclined surface is close to or overlaps the top of the mobile base 21, and the lower end is close to the top of the dam slope, so that the guide part 231 can connect the top of the mobile base 21 and the top of the dam slope. After the slope stabilization work of the dam slope is completed, the slope stabilization component 1 is pulled to the top of the dam slope by the winch 22, and then the slope stabilization component 1 can be further pulled onto the mobile base 21 through the connection of the guide part 231, thereby completing the retrieval of the slope stabilization component 1 and facilitating its subsequent transportation.

[0060] In addition, the guide part 231 also has the effect of preventing the movable base 21 and the transition member 23 from overturning under the tension of the slope stabilization component 1. When the movable base 21 and the transition member 23 tilt under the tension, the lower end of the guide part 231 can abut against the ground surface to form a tilting support structure, thereby preventing the movable base 21 and the transition member 23 from tilting further.

[0061] The guide wheel 24 is detachably mounted on the movable base 21 or the transition piece 23. The guide wheel 24 is used to guide the rope 25 so that the direction of the tension of the rope 25 on the slope stabilization component 1 is as parallel as possible to the slope surface of the dam face.

[0062] Furthermore, the transition component 23 has a movable part 232, which can be a wheel. After the slope stabilization component 1 completes the slope stabilization work in a certain area of ​​the dam slope, personnel can use the winch 22 to pull the slope stabilization component 1 onto the guide part 231 of the transition component 23, and use the transition component 23 to temporarily place the slope stabilization component 1. Afterwards, the movable base 21 can drive the transition component 23 to move on the top of the dam. After moving, the winch 22 releases the rope 25, allowing the slope stabilization component 1 to roll from the guide part 231 to other areas of the dam slope, and then carry out slope stabilization work in other areas.

[0063] In some embodiments, the slope stabilization assembly 1 further includes a vibrating element disposed on the end face or inside the compaction roller 12. When the compaction roller 12 compacts the dam slope, the vibrating element vibrates, causing the compaction roller to vibrate as well. This vibration eliminates air bubbles in the concrete and compacts the interior of the concrete. The combination of vibration and compaction during rolling enhances the compaction effect of the compaction roller 12 on the concrete. The vibrating element is a vibrator.

[0064] In one scenario, the vibrating element can vibrate both uphill and downhill on the compaction roller, thereby enabling the compaction roller to help compact the concrete internally through vibration, improving compaction efficiency, regardless of whether it is going uphill or downhill.

[0065] In another scenario, the vibrating element vibrates only when the roller moves towards the top of the dam slope; it does not vibrate when the roller 12 moves towards the bottom of the dam slope. This is because when the roller vibrates, a small amount of sand and gravel may be dislodged from the concrete surface around it, especially uncompacted concrete, which is more prone to dislodging.

[0066] When the roller moves toward the top of the dam slope, the facing side of the roller faces upward. Even if a small amount of sand and gravel is dislodged on the facing side, it will be immediately compacted by the roller 12. However, when the roller 12 moves toward the bottom of the dam slope, the facing side of the roller 12 faces downward. If there is sand and gravel dislodged on the facing side, the dislodged sand and gravel will roll to the bottom of the slope before being compacted by the roller 12, resulting in waste of sand and gravel.

[0067] Furthermore, the dam slope stabilization device also includes a condition monitoring component and a control module. Both the condition monitoring component and the vibration component are connected to the control module via signals.

[0068] The status detection device is used to detect the movement status of the slope stabilization component 1. For example, the status detection device can be a distance sensor, which is mounted on the frame 11. By setting an indicator at the top or bottom of the slope of the dam face and measuring the distance between the indicator and the distance sensor, the control module can determine whether the slope stabilization component 1 is in an uphill or downhill state based on the distance between the indicator and the distance sensor. Therefore, the control module can control the vibrator to vibrate when the slope stabilization component 1 is in an uphill state and control the vibrator to stop vibrating when the slope stabilization component 1 is in a downhill state. The control module can be mounted on the frame 11, and the control module and the vibrator can be connected wirelessly (e.g., via Wi-Fi, Bluetooth, or other wireless communication).

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, the slope stabilization component 1 further includes an adjustment unit 13, a first trimmer 14, and a second trimmer 15.

[0070] The adjustment unit 13 includes a drive component 131 and a connector 132. The connector 132 is rotatably connected to the frame 11 and is connected to the first trimmer 14. The drive component 131 can be a linear drive component such as an electric push rod. One end of the drive component 131 is hinged to the frame 11, and the other end is hinged to the connector 132.

[0071] When the drive member 131 extends or retracts, it can drive the connecting member 132 to rotate, thereby driving the first trimming member 14 to move closer to or away from the dam slope.

[0072] The first trimming component 14 is located on the side of the rolling roller 12 near the bottom of the dam slope, and is used to trim the dam slope.

[0073] For example, the first trimming element 14 can be a scraper or a first rolling roller.

[0074] Case 1: The first trimming part 14 is a scraper.

[0075] When the roller 12 moves uphill, the scraper can flatten the area that the roller 12 has rolled over, eliminating the indentations caused by the roller 12.

[0076] When the compaction roller 12 moves downhill, the following conditions need to be considered: If the concrete on the uphill side of the compaction roller 12 has not been compacted, the scraper can avoid contact with the concrete to prevent pushing it away; alternatively, by driving the scraper to move closer to or further away from the dam slope, the scraper can contact the concrete but the pressure between them will not be too great. This allows the scraper to only perform a preliminary, slight smoothing of the concrete surface as it moves with the frame 11, without pushing away all the concrete. The smoothed concrete, after being compacted by the compaction roller 12, will result in a smoother dam slope. When the concrete on the uphill side of the compaction roller 12 has already been compacted, the scraper can smooth the compacted concrete as it moves downhill.

[0077] like Figure 2 and Figure 3 As shown, in the second scenario, the first trimming component 14 is the first compaction roller. Whether moving uphill or downhill, the dam slope will be compacted by the compaction wheel 12 and the first compaction roller, improving the compaction effect.

[0078] The second trimming component 15 is connected to the frame 11 and is located on the side of the compaction roller 12 near the top of the dam slope. The second trimming component 15 can be a scraper or a second compaction roller and is used to scrape or compact the dam slope.

[0079] Furthermore, the first trimming component 14 includes a straight section 141 and a gradient section 142. The length of the straight section 141 is greater than the length of the rolling wheel 12. The two ends of the straight section 141 are smoothly connected to the gradient section 142. Along the direction away from the straight section 141, the distance between the gradient section 142 and the dam slope gradually increases.

[0080] Specifically, when the first trimming part 14 is a scraper, the straight section 141 can be a straight plate, and the gradient section 142 can be an arc-shaped plate. When the first trimming part 14 is the first rolling wheel 12, the straight section 141 is cylindrical, and the gradient section 142 is conical.

[0081] When the first trimming part 14 comes into contact with the dam slope, the straight part 141 fits into the dam slope.

[0082] To achieve better rolling and compaction, the rolling wheel 12 is usually quite heavy. This may leave indentations on the areas rolled by the rolling wheel 12, especially on the areas rolled by the edge of the rolling wheel 12. The indentations are more obvious and will affect the aesthetics of the dam slope.

[0083] To address the aforementioned indentation problem, the first trimming component 14 in this embodiment can be a scraper or a first rolling wheel 12. Since the length of the straight portion 141 of the first trimming component 14 is greater than the length of the rolling wheel 12, the first trimming component 14 can smooth or flatten the area rolled by the rolling wheel 12 during the movement of the frame 11, thereby eliminating indentations. Furthermore, because the straight portion 141 and the transition portion 142 of the first trimming component 14 have a smooth transition, the area rolled at the junction of the straight portion 141 and the transition portion 142 is less prone to obvious indentations. Moreover, the pressure exerted by the first trimming component 14 on the dam slope is much less than the pressure exerted by the rolling wheel 12 on the dam slope, further making it less likely for obvious indentations to appear in the area smoothed or rolled by the first trimming component 14.

[0084] In addition, since the compaction wheel 12 vibrates during the uphill process, the vibration may cause sand and gravel to fall off and landslide. Although the sand and gravel that fall off on the uphill side of the compaction wheel 12 can be compacted by the compaction wheel 12, there is still a certain probability that the sand and gravel on the side of the compaction wheel 12 will landslide. Furthermore, the sand and gravel that fall off on the uphill side of the compaction wheel 12 may also slide away from both sides of the compaction wheel 12 during the slide.

[0085] In response to the aforementioned gravel landslide problem, the first trimming component 14 in this embodiment can be a first rolling roller. The straight portion 141 of the first rolling roller can roll down the gravel and prevent further landslides.

[0086] Finally, by adjusting the first trimmer 14 to move closer to or further away from the dam slope, the working state of the slope stabilization component 1 can be changed, thereby switching the slope stabilization component 1 between the first state, the second state, and the third state. First, by controlling the shape of the frame 11, the center of gravity of the slope stabilization component 1 is located on the side of the compaction wheel 12 near the bottom of the dam slope.

[0087] In the first state, the second trimmer 15 detaches from the dam slope (this can be achieved by setting the connection position between the second trimmer 15 and the frame 11), and the adjustment unit 13 drives the first trimmer 14 to detach from the dam slope. At this time, only the compaction wheel 12 contacts and compacts the dam slope. Although the center of gravity of the slope stabilization assembly 1 is located on the side of the compaction wheel 12 near the bottom of the dam slope, the side of the frame 11 near the top of the dam slope (defined as the front side) is tractioned by the rope 25. Therefore, the side of the frame 11 near the bottom of the dam slope (defined as the rear side) will not fall or tilt and contact the dam slope.

[0088] The adjustment unit 13 drives the first trimming part 14 to contact the dam slope, so that both the rolling wheel 12 and the first trimming part 14 are in contact with the dam slope, while the second trimming part 15 remains detached from the dam slope. At this time, the slope stabilization component 1 is in the second state.

[0089] In the second state, the connecting member 132 is driven to rotate further by the driving member 131, causing the frame 11 to flip over. The second trimming member 15 can move to contact the dam slope. At this time, the rolling wheel 12, the first trimming member 14 and the second trimming member 15 are all in contact with the dam slope, and the slope stabilization component 1 is in the third state.

[0090] By controlling the slope stabilization component 1 to be in different states, different slope stabilization effects can be achieved.

[0091] Alternatively, the desired slope stabilization method can be achieved by setting counterweights on the frame 11.

[0092] For example, a counterweight can be set on the front side of the frame 11 so that even if the second trimming part 14 is separated from the dam slope, the second trimming part 15 can still abut against the dam slope. At this time, the slope stabilizing component 1 stabilizes the slope through the rolling wheel 12 and the second trimming part 15, and the slope stabilizing component 1 is in the fourth state.

[0093] Alternatively, a counterweight can be installed on the rear side of the frame 11 to change the force between the first trimmer 14 and the dam slope in the second state, thereby enabling the first trimmer 14 to trim the dam slope with appropriate force.
