Description

Technical Field

[0001] The invention belongs to the technical field of slope protection and buffering, and in particular relates to a loess slope protection and buffering energy dissipation device. Background Art

[0002] Loess slopes are common geological phenomena in loess regions. Changes in groundwater levels, flow directions, and infiltration of surface water will affect the stability of loess slopes. Long-term immersion of groundwater will soften loess and reduce its strength, while large amounts of surface water infiltration will increase the weight of the slope and may generate dynamic water pressure, promoting slope instability. Climate conditions such as rainfall, drought, and wind have a significant impact on the stability of loess slopes. Heavy rains will quickly saturate loess, increase the weight of the slope and pore water pressure; long-term droughts will cause loess to dry and crack, providing channels for rainwater infiltration; strong winds may erode the slope surface and weaken the stability of the slope; human activities such as excavating the foot of the slope, piling on the top of the slope, and building engineering facilities may change the original stress state and hydrogeological conditions of the loess slope, thereby causing slope instability. For example, excavation at the foot of the slope will weaken the support force of the slope, causing the upper slope to be unbalanced; piling on the top of the slope will increase the pressure of the slope, and when it exceeds its bearing capacity, it will cause a landslide.

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0028] like Figures 1 to 8As shown, an embodiment of the present invention proposes a loess slope protection buffering and energy dissipation device, including a mounting plate 1, the upper surface of the mounting plate 1 is fixedly connected to a baffle plate 2, one side of the baffle plate 2 is slidably connected to two sliding rods 3, one end of the sliding rod 3 is fixedly connected to a buffer plate 4, the lower surface of the mounting plate 1 is fixedly connected to two first fixing columns 5 and two second fixing columns 6, a reinforcement component 7 is arranged in the first fixing column 5 and the second fixing column 6, a plurality of through grooves are arranged on the baffle plate 2, one side of the buffer plate 4 is fixedly connected to a rubber plate 8, one end of all the sliding rods 3 are fixedly connected to a limiting plate 9, a first buffer spring 10 is fixedly connected between the limiting plate 9 and the mounting plate 1, and when in use, the mounting plate 1 is placed on the ground, and the two first fixing The column 5 and the second fixed column 6 are fixed on the ground. The device is provided with a baffle 2. When the loess slope becomes unstable, the soil and stones first impact the rubber plate 8 on one side of the buffer plate 4. The rubber plate 8 first deforms to buffer and absorb energy, and then the impact force impacts the buffer plate 4, causing the sliding rod 3 to slide on the baffle 2, pulling the first buffer spring 10 to buffer and absorb energy again. Finally, the baffle 2 is used to block the stones and loess. The rubber plate 8 and the first buffer spring 10 are provided to buffer and absorb energy, thereby protecting the baffle 2 and the mounting plate 1, reducing the damage to the baffle 2 and the mounting plate 1, and extending the service life of the baffle 2 and the mounting plate 1. The through groove on the baffle 2 is used to discharge rainwater.

[0029] like Figure 2 , Figure 3 as well as Figure 4 As shown, the first fixing column 5 and the second fixing column 6 are located on both sides of the mounting plate 1, and the first fixing column 5 and the second fixing column 6 both penetrate the mounting plate 1. The first fixing column 5 and the second fixing column 6 are both provided with a plurality of circular through holes. The reinforcement component 7 includes a plurality of plug rods 71, and the plug rods 71 ​​are located in the circular through holes. The plug rods 71 ​​can slide in the circular through holes. One end of the plug rod 71 is fixedly connected to the arc block 72, and one side of the arc block 72 is fixedly connected to the reset spring 73. The first fixing column 5 and the second fixing column 6 are both movably provided with ejection blocks 74. When the slope is not unstable, the mounting plate 1 It is fixed by two first fixing columns 5 and second fixing columns 6, and the first fixing columns 5 and second fixing columns 6 are inserted into the soil to support the mounting plate 1. When replacing the device or repairing it, the mounting plate 1 can be directly lifted up to remove the device, which is easy to operate. When instability occurs, the ejection block 74 is used to push the insertion rod 71 on the first fixing column 5 and the second fixing column 6, and the insertion rod 71 slides and inserts into the soil, thereby increasing the stability of the mounting plate 1, making it easier for the baffle plate 2 to resist the impact force of the slope instability, and avoiding the impact force from hitting the baffle plate 2, causing the mounting plate 1 to separate from the baffle 2.

[0030] like Figure 5 as well as Figure 6As shown, both sides of the baffle 2 are fixedly connected to the support plate 11, and three blocking devices 12 are arranged on the baffle 2. The blocking device 12 includes two cross bars 121, and the cross bars 121 are slidably connected to the baffle 2. The cross bars 121 penetrate the baffle 2, and the outer sides of the cross bars 121 are fixedly connected to two limiting rings 122, and the limiting rings 122 are located on both sides of the baffle 2. A second buffer spring 123 is fixedly connected between the limiting rings 122 and the baffle 2, and one end of the two cross bars 121 is fixedly connected to a vertical rod 124, and a plurality of rubber ropes 125 are fixedly connected between the two vertical rods 124. The rubber ropes 125 are vertically distributed. When the slope is unstable, the soil and stones impact the rubber ropes 125, and the rubber ropes 125 block larger objects such as stones. 125 is deformed and buffers energy through its own elasticity. Then the rubber rope 125 pulls the cross bar 121 to slide, and buffers again through the second buffer spring 123, so that the stone stays on one side of the rubber rope 125, and the rubber rope 125 can also divert the rolling soil. The three rubber ropes 125 are densely distributed to buffer the soil. The soil and rainwater first rush through multiple rubber ropes 125 for buffering, and then are buffered by the buffer plate 4, the rubber plate 8, and the first buffer spring 10 to improve the buffering energy absorption effect. By setting the elastic rope, the rolling stone is blocked and buffered, so that the stone is blocked on the outside of the elastic rope, avoiding the stone and soil from impacting the baffle 2 together, causing the baffle 2 to deform and be damaged.

[0031] like Figure 5 and Figure 6As shown, two driving assemblies 13 are provided on one side of the baffle 2. The driving assemblies 13 are used to drive the ejection blocks 74 in the two first fixed columns 5. The driving assembly 13 includes two support plates 131. The support plates 131 are fixedly connected to the baffle 2. A circular through groove is provided on the support plates 131. The upper surface of the ejection block 74 in the first fixed column 5 is fixedly connected to a threaded rod 132. The threaded rod 132 penetrates the first fixed column 5 upward and is threadedly connected to the first fixed column 5. The opposite sides of the two support plates 131 are rotatably connected to the rotating ring 14. A plurality of toggle plates 15 are fixedly connected between the two rotating rings 14. The inner sides of all toggle plates 15 are fixedly connected to a fixed plate 16. The fixed plate 16 is threadedly connected to the threaded rod 132. The threaded rod 132 penetrates the fixed plate 16. One side of all cross bars 121 is provided with an installation groove. The installation groove is rotatably connected to a toggle rod 17. A toggle spring is provided at the connection between the toggle rod 17 and the cross bar 121. The toggle rod 17 is used to When the toggle plate 15 is toggled, when the stone hits one of the rubber ropes 125, the elastic rope pulls the cross bar 121 to slide for buffering, and the cross bar 121 moves, driving the toggle rod 17 to move, and the toggle rod 17 is against the side wall of the mounting groove, and the toggle rod 17 toggles the toggle plate 15, so that the rotating ring 14 rotates between the support plates 131, and the toggle plate 15 drives the fixed plate 16 to rotate, and the threaded rod 132 is controlled to descend, and the threaded rod 132 pushes the ejection block 74 to descend, and the ejection block 74 pushes the insertion rod 71 in the first fixing column 5 to be inserted into the soil, thereby increasing the fixing effect of the first fixing column 5 on the mounting plate 1, and when instability does not occur, the insertion rod 71 will not be inserted into the soil. At this time, it is relatively easy to remove the mounting plate 1, which is convenient for maintenance and replacement, and when instability occurs, the insertion rod 71 is driven to be inserted into the soil through the impact force of the soil and stones, so as to reinforce the first fixing column 5, without manual operation, and is more convenient and safe to use.

[0032] like Figure 6 and Figure 7As shown, the lower surface of the support plate 131 is fixedly connected to the vertical rod 18, and the outer side of the vertical rod 18 is rotatably connected to the blocking rod 19. A torsion spring is provided at the connection between the blocking rod 19 and the vertical rod 18. The lower surface of the support plate 131 is fixedly connected to the fixing rod 20, and the fixing rod 20 is located on one side of the blocking rod 19. When the toggle rod 17 drives the toggle plate 15 to rotate, the toggle plate 15 pushes the blocking rod 19 to rotate, and the blocking rod 19 rotates to avoid. When the toggle rod 17 is out of contact with the toggle plate 15, the blocking rod 19 is reset under the action of the torsion spring and reinserted between the toggle plates 15. When the cross bar 121 slides in the opposite direction and resets under the action of the second buffer spring 123, The toggle rod 17 touches the toggle plate 15 to reverse, and the toggle rod 17 enters the installation groove to avoid it and slides past one side of the toggle plate 15. At this time, the toggle plate 15 and the rotating ring 14 are blocked by the blocking rod 19 and the fixed rod 20 to prevent the rotating ring 14 and the toggle plate 15 from reversing. When in use, the greater the force with which the stone impacts the rubber rope 125, the more times the rubber rope 125 is impacted, and the greater the number and distance of the horizontal sliding of the cross bar 121, the greater the amplitude of rotation of the toggle plate 15, the greater the height to which the fixed plate 16 drives the threaded rod 132 to descend, and the greater the length of the insertion rod 71 pushed into the soil by the ejection block 74, thereby making the mounting plate 1 more stable.

[0033] like Figure 1 , Figure 2 and Figure 8 As shown, the upper surface of the ejection block 74 in the two second fixed columns 6 is fixedly connected to the round rod 21, the round rod 21 penetrates the second fixed column 6 and is slidably connected to the second fixed column 6, the upper end of the round rod 21 is fixedly connected to the fixed block 22, the fixed block 22 and the second fixed column 6 are fixedly connected to the support spring 23, one side of the mounting plate 1 is fixedly connected to the two fixed seats 24, the two fixed seats 24 are rotatably connected to the rotating plate 25, the inner side of the rotating plate 25 is pressed on the fixed block 22, the upper surface of the fixed block 22 is arc-shaped, large objects such as stones hit the rubber rope 125 for buffering and energy absorption, when the large objects such as stones are stationary, they are pressed on the rotating plate 25, and the rotating plate 25 is caused to rotate downward by gravity. , squeezing the upper end of the round rod 21 on the second fixed column 6, causing the round rod 21 to slide down, pushing the ejection block 74 on the second fixed column 6 down, and pushing the insertion rod 71 on the second fixed column 6 to be inserted into the soil, thereby increasing stability. Therefore, when instability occurs, the stone stays above the mounting plate 1 under the obstruction of the rubber rope 125, and the rotating plate 25 is pressed down by gravity, so that the insertion rod 71 of the second fixed column 6 is inserted into the soil, thereby increasing stability. The greater the weight on the rotating plate 25, the higher the stability of the second fixed column 6. Only after the heavy objects on the rotating plate 25 are cleared, can the rotating plate 25 be reset to retract the insertion rod 71, thereby increasing safety and avoiding instability of the baffle 2 and the mounting plate 1 when cleaning the stones after instability.

[0034] Working principle: The mounting plate 1 is placed on the ground and fixed to the ground by two first fixing columns 5 and a second fixing column 6. When the loess slope becomes unstable, the soil and stones impact the rubber rope 125 first. The rubber rope 125 stops larger objects such as stones, and the rubber rope 125 is deformed and absorbs energy through its own elasticity. Then the rubber rope 125 pulls the cross bar 121 to slide, and is buffered again by the second buffer spring 123. The cross bar 121 moves, driving the toggle rod 17 to move. The toggle rod 17 rests on the side wall of the mounting groove. The toggle rod 17 toggles the toggle plate 15, causing the rotating ring 14 to rotate between the support plates 131. The toggle plate 15 drives the fixed plate 16 to rotate, controlling the threaded rod 13 2 descends, the threaded rod 132 pushes the ejection block 74 to descend, and the ejection block 74 pushes the insertion rod 71 in the first fixed column 5 to be inserted into the soil. When the stone stays on one side of the rubber rope 125, the rubber rope 125 can also divert the rolling soil. The soil can be buffered by the three densely distributed rubber ropes 125. The soil and rainwater first rush through the multiple rubber ropes 125 for buffering. When large objects such as stones are stationary, they are pressed on the rotating plate 25, and the rotating plate 25 is caused to rotate downward by gravity, squeezing the upper end of the round rod 21 on the second fixed column 6, causing the round rod 21 to slide down, pushing the ejection block 74 on the second fixed column 6 to descend, and pushing the insertion rod 71 on the second fixed column 6 to be inserted into the soil.
