Description

Technical Field

[0001] The present invention belongs to the field of geotechnical engineering technology and geological disaster prevention and mitigation engineering, and in particular relates to a high-level slope disaster chain prevention and control structure and a method thereof. Background Art

[0002] High-level slope disaster chain prevention and control structures usually refer to prevention and control measures and structures taken for high-level slopes (i.e. slopes located at relatively large height differences) to prevent or reduce a series of chain reactions or secondary disasters caused by disasters such as slope landslides and collapses. The "disaster chain" here refers to the chain reaction caused by a disaster, which may involve the chain effect of multiple disasters such as landslides turning into slope debris flows, debris flows, and rockfall disasters causing road damage, building damage, etc.;

[0003] In existing slope protection projects, the bottom of high slopes is usually a highway, railway or other buildings for vehicles to pass. However, such high slopes are generally located in mountainous areas with fragile geological environments, strong geological structures, and developed geological disasters. High-level landslides and collapse disasters often occur. After the collapse and landslide disaster occurs, it disintegrates in the process of moving down the slope to form rockfall or debris flow or slope debris flow disasters. Due to the high position and large potential energy of the collapse and sliding body, the kinetic energy converted is huge, and the impact speed and impact energy of the rockfall or debris flow are large. Once the rockfall or debris flow hits the road, it will pose a serious traffic safety hazard. In addition, due to the large catchment area of ​​the high slope, under heavy rainfall weather conditions, the rainwater confluent on the upper side will form a significant scouring and scraping effect on the slope surface, carrying the slope rock and soil downward to form a slope debris flow disaster, posing a greater threat to linear structures such as the road below and driving safety, exacerbating safety hazards and disasters.

[0024] A method for using a high-level slope disaster chain prevention and control structure, the method comprising the following steps:

[0025] The device is directly assembled on a high slope that needs to be prevented and controlled. The retaining wall is located at the bottom of the slope, the positioning rod is located at the top of the slope, the supporting rod and the guide frame are located on the inclined surface of the slope. When rockfall occurs on the upper side of the slope, the falling rock will first fall on the movable guide frame at the corresponding position during the falling process. Due to the impact of the falling rock, the movable guide frame, the limit plate and the sliding block are driven to move downward, thereby limiting the falling speed of the falling rock and causing the falling rock to fall slowly. In addition, due to the inclined settings on both sides of the movable guide frame, the falling rock will be guided to slide into the corresponding guide frame, and the falling rock in the guide frame will be guided to slide into the diversion storage frame, thereby blocking and guiding the falling rock to prevent the falling rock from affecting the road and moving vehicles at the bottom of the slope. In the process of the movable guide frame moving downward, the extrusion wheel and the rotating wheel will be driven to move downward, and the friction between the rotating wheel and the supporting rod will control the rotation of the rotating wheel and the extrusion wheel. In the process of the rotation of the extrusion wheel, the movable guide frame will be knocked and vibrated, and the gravel and debris that may be accumulated on the surface of the movable guide frame will be vibrated and cleaned;

[0026] The supporting rods and positioning rods increase the stability of the retaining wall itself, making the retaining wall's own support and blocking effect on the slope more ideal. The covering net covers the inclined surface of the slope to prevent stones and soil from sliding down at will, and plants can be planted between the covering nets to stabilize the soil at the inclined surface of the slope. When it rains, the water flows from top to bottom along the inclined surface of the slope, and the water flows into the movable guide frame and the bearing frame through the water inlet net. The bearing frame moves downward as the water in the bearing frame increases. The bearing frame slides downward in the movable guide frame and fits on the covering net, blocking and guiding the downward flowing water, so that the water flows into the guide frame and the diversion storage frame through the movable guide frame, avoiding the impact of the water on the inclined surface of the slope and causing the soil at the inclined surface to flow.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, a movable guide frame, a sliding hole, a first elastic component, a guide frame and a diversion storage frame are used. When rockfall occurs, its impact force will drive the movable guide frame, the limit plate and the sliding block to move downward in coordination. Through this mechanism, the falling speed of the rockfall is effectively limited, so that the rockfall can fall slowly and steadily. The inclined design on both sides of the movable guide frame cleverly guides the rockfall to slide into the corresponding guide frame, and then further guides the rockfall in the guide frame to slide into the diversion storage frame. This series of designs not only realizes the effective blocking and guiding of rockfall, but also avoids the rockfall from driving stones and soil down when falling along the inclined surface of the slope, thereby greatly reducing the safety hazards caused by rockfall to the road at the bottom of the slope and the vehicles traveling. At the same time, the present invention also adopts the design of covering the lattice shell to further enhance the protection effect of the slope.

[0029] 2. In the present invention, a movable guide frame, a bearing frame, a third elastic component, a water outlet and a water inlet net are adopted. When precipitation occurs, the water flow is first guided into the movable guide frame and the bearing frame through the water inlet net shell. As the amount of water in the bearing frame increases, it moves downward under the action of gravity and fits tightly on the covering net to form an effective blocking and guiding mechanism. This design cleverly utilizes the synergistic effect of the movable guide frame and the bearing frame, so that the downward flowing water flow is effectively guided to the guide frame and the diversion storage frame, thereby avoiding the water flow directly impacting the inclined surface of the slope, reducing soil flow and erosion. The present invention not only significantly improves the protective effect of the inclined surface of the slope, but also greatly enhances the overall stability and safety of the slope, providing an ideal technical guarantee for disaster prevention and control of high-level slopes.

[0030] 3. In the present invention, a guide block, an extended sliding frame, a second elastic component, an extrusion wheel, a rotating wheel and a knocking rod are used. When the mobile guide frame moves downward, the extrusion wheel and the rotating wheel move downward accordingly, and their rotation is controlled by the friction between the extrusion wheel and the supporting pull rod. This design enables the extrusion wheel to effectively knock and vibrate the mobile guide frame during rotation, thereby thoroughly cleaning the gravel and debris that may be accumulated on the surface of the mobile guide frame, avoiding the potential risks caused by the accumulation of stones. The water inlet net on the surface of the mobile guide frame also benefits from the vibration effect, realizes self-cleaning, and effectively prevents the occurrence of blockage. This series of designs ensures that during the protection process, the treatment of stones and water flows can be carried out more stably and continuously, greatly improving the overall efficiency and reliability of the high-level slope disaster chain prevention and control structure.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Please refer to the attached Figure 1 -Attached Figure 8The present invention provides a technical solution: a high-level slope disaster chain prevention and control structure, comprising a retaining wall 1, a drainage groove 2 is opened at the left position of the upper surface of the retaining wall 1, a plurality of support rods 5 (for example, 3 as shown in the figure) are fixedly connected to the retaining wall 1, a positioning rod 7 is fixedly connected to the top of the plurality of support rods 5, a covering guide device 6 is fixedly connected between two adjacent support rods 5, a plurality of sliding holes 9 (for example, 3 as shown in the figure) are opened through the side of the support rod 5, a sliding buffer mechanism 11 is arranged in the sliding hole 9, a movable guide frame 10 is fixedly connected to the sliding buffer mechanism 11, an extension sliding frame 12 is fixedly connected to the lower surface of the movable guide frame 10, a vibration guide mechanism 13 is arranged in the extension sliding frame 12, the vibration guide mechanism 13 is arranged under the movable guide frame 10, a plurality of sliding grooves 14 (for example, 2) are opened on the inner wall of the movable guide frame 10, a movable water retaining mechanism 15 is arranged in the movable guide frame 10 and the sliding groove 14, and a water inlet net 16 is penetrated on the upper side of the movable guide frame 10.

[0043] The retaining wall 1, the supporting rod 5 and the positioning rod 7 are combined into a whole structure to achieve shielding and protection of the slope position, and the drainage ditch 2 is used to guide the water flow at the bottom of the retaining wall 1.

[0044] A positioning anchor bolt 3 is fixedly connected to the lower side of the retaining wall 1 , and a diversion storage frame 4 is fixedly connected to the right side of the retaining wall 1 . The position of the diversion storage frame 4 corresponds to the bottom end of the covering guide device 6 .

[0045] The positioning anchor bolts 3 enable the retaining wall 1 to be stably assembled at the bottom of the slope.

[0046] The right side surface of the positioning rod 7 is fixedly connected with a mounting bolt 8 , and the movable guide frame 10 is set to be V-shaped, and the front and rear end positions of the movable guide frame 10 both correspond to the covering guide device 6 .

[0047] The covering guide device 6 includes a guide frame 61 , the bottom end of the guide frame 61 corresponds to the guide storage frame 4 , the upper side and the bottom end of the guide frame 61 are in an open state, and the guide frame 61 corresponds to the end position of the movable guide frame 10 .

[0048] A positioning tooth 62 is fixedly connected to the lower surface of the guide frame 61, a covering net 63 is fixedly connected to the side of the guide frame 61 close to the supporting rod 5, and three connecting frames 64 are fixedly connected to the side of the covering net 63. The connecting frames 64 are fixedly connected to the side of the supporting rod 5. The length of the connecting frames 64 is greater than the length of the sliding hole 9. The length setting of the connecting frames 64 allows the sliding buffer mechanism 11 to slide normally in the sliding hole 9.

[0049] The guide frame 61 can guide the stones or water that slide down the side of the movable guide frame 10, block and guide the stones and water that move from top to bottom, so that the water or stones move into the guide frame 61, and prevent the stones and water from carrying the soil on the slope surface down sharply during the falling process.

[0050] The sliding buffer mechanism 11 includes a sliding block 111 slidably connected in the sliding hole 9. The two side surfaces of the sliding block 111 outside the sliding hole 9 are fixedly connected to a limiting plate 112. The limiting plate 112 is slidably connected to the side of the supporting rod 5. The size of the limiting plate 112 is larger than the size of the sliding hole 9. The upper surface of the limiting plate 112 is fixedly connected to the movable guide frame 10. The part of the side of the sliding block 111 located in the sliding hole 9 is fixedly connected to the first elastic component 113. The first elastic component 113 is fixedly connected to the inner wall of the sliding hole 9.

[0051] The sliding block 111 moves downward to a certain extent in the sliding hole 9. At the same time, the movement process will squeeze the first elastic component 113 to deform, so that the movable guide frame 10 is impacted and moves downward to achieve buffering protection for the movable guide frame 10 and the impact. The limit plate 112 and the rectangular sliding block 111 can ensure that the sliding block 111 will not rotate or tilt or shake.

[0052] The vibration guide mechanism 13 includes a guide block 131, which is slidably connected in the extension slide frame 12. The side of the guide block 131 is fixedly connected with a second elastic component 132, and the second elastic component 132 is fixedly connected in the extension slide frame 12. A sliding plate 133 is fixedly connected under the guide block 131, and a knocking rod 138 is fixedly connected to the outside of the sliding plate 133. The knocking rod 138 is arranged outside the movable guide frame 10.

[0053] The side of the sliding plate 133 is slidably connected to an extrusion wheel 134, and the side of the extrusion wheel 134 is penetrated by a rotating shaft 135. The rotating shaft 135 is fixedly connected to a rotating wheel 136 outside. The rotating wheel 136 is arranged on the supporting pull rod 5. The rotating shaft 135 is rotatably connected to two support seats 137 outside. The support seats 137 are fixedly connected to the outside of the movable guide frame 10.

[0054] The guide block 131 slides in the extended sliding frame 12, guides and limits the movement of the sliding plate 133 and the knocking block, and ensures that the knocking rod 138 moves stably in a straight line. In the process of the mobile guide frame 10 moving downward, the extrusion wheel 134 and the rotating wheel 136 will be driven to move downward. The friction between the rotating wheel 136 and the supporting pull rod 5 will control the rotation of the rotating wheel 136 and the extrusion wheel 134. The raised position of the extrusion wheel 134 can squeeze the knocking rod 138 away from the mobile guide frame 10, and cooperate with the subsequent second elastic component 132 to control the rapid reset of the knocking rod 138. During the rotation of the extrusion wheel 134, the mobile guide frame 10 will be knocked and vibrated, and the gravel and debris that may be accumulated on the surface of the mobile guide frame 10 will be vibrated and cleaned.

[0055] The movable water retaining mechanism 15 includes a supporting frame 151 slidably connected in the movable guide frame 10, a connecting block 152 is fixedly connected to the side of the supporting frame 151, the connecting block 152 is slidably connected in the sliding groove 14, a third elastic component 153 is fixedly connected to the connecting block 152, the third elastic component 153 is fixedly connected in the sliding groove 14, and a water outlet hole 154 is opened under the supporting frame 151.

[0056] The water flows into the movable guide frame 10 and the supporting frame 151 through the water inlet net 16. The water in the supporting frame 151 increases and moves downward. The supporting frame 151 slides downward in the movable guide frame 10 and fits on the covering net 63, thereby blocking and guiding the downward flowing water. The movable guide frame 10 and the supporting frame 151 cooperate to guide the water flow more fully. The water in the supporting frame 151 will gradually be discharged through the water outlet 154. At the same time, with the elastic force of the third elastic component 153, the supporting frame 151 can be controlled to reset upward, and the supporting frame 151 is separated from the covering net 63, which can ensure that the movable guide frame 10 can smoothly perform a small buffering action along the sliding hole 9.

[0057] A method for using a high-level slope disaster chain prevention and control structure, the method comprising the following steps:

[0058] The device is directly assembled on a high slope that needs to prevent and control disasters. The retaining wall 1 is located at the bottom of the slope, the positioning rod 7 is located at the top of the slope, the support rod 5 and the guide frame 61 are located on the slope. When rocks fall on the upper side of the slope, the rocks will first fall on the movable guide frame 10 at the corresponding position. The impact of the rocks will drive the movable guide frame 10, the limit plate 112 and the sliding block 111 to move downward, limiting the falling speed of the rocks, so that the rocks fall slowly, and the inclined settings on both sides of the movable guide frame 10 will guide the rocks to slide. To the corresponding guide frame 61, guide the falling rocks in the guide frame 61 to slide into the diversion storage frame 4, block and guide the falling rocks, and prevent the falling rocks from affecting the road and moving vehicles at the bottom of the slope. In the process of the mobile guide frame 10 moving downward, the extrusion wheel 134 and the rotating wheel 136 will be driven to move downward. The friction between the rotating wheel 136 and the supporting rod 5 will control the rotation of the rotating wheel 136 and the extrusion wheel 134. In the process of the rotation of the extrusion wheel 134, the mobile guide frame 10 will be knocked and vibrated, and the gravel and debris that may be accumulated on the surface of the mobile guide frame 10 will be vibrated and cleaned;

[0059] The supporting rods 5 and the positioning rods 7 increase the stability of the retaining wall 1 itself, making the retaining wall 1's own support and blocking effect on the slope more ideal. The covering net 63 covers the inclined surface of the slope to prevent stones and soil from sliding down at will, and plants can be planted between the covering nets 63 to stabilize the soil at the inclined surface of the slope. When it rains, the water flows from top to bottom along the inclined surface of the slope, and the water flows into the movable guide frame 10 and the bearing frame 151 through the water inlet net 16. The bearing frame 151 moves downward as the water in the bearing frame 151 increases. The bearing frame 151 slides downward in the movable guide frame 10 and fits on the covering net 63, thereby blocking and guiding the downward flowing water, so that the water flows through the movable guide frame 10 into the guide frame 61 and the diversion storage frame 4, thereby avoiding the impact of the water on the inclined surface of the slope and causing the soil at the inclined surface to flow.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A method for using a high-level slope disaster chain prevention and control structure, according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: The device is directly assembled on a high slope that needs to be prevented and controlled from disasters. The retaining wall (1) is located at the bottom of the slope, the positioning rod (7) is located at the top of the slope, and the support rod (5) and the guide frame (61) are located on the inclined surface of the slope. When rockfall occurs on the upper side of the slope, the rockfall will first fall on the movable guide frame (10) at the corresponding position. The impact of the rockfall drives the movable guide frame (10), the limit plate (112) and the sliding block (111) to move downward, thereby limiting the falling speed of the rockfall and causing the rockfall to fall slowly. In addition, the inclined settings on both sides of the movable guide frame (10) will guide the rockfall to slide to the corresponding In the guide frame (61), the falling rocks in the guide frame (61) are guided to slide into the diversion storage frame (4), thereby blocking and guiding the falling rocks to prevent the falling rocks from affecting the road and moving vehicles at the bottom of the slope. During the downward movement of the mobile guide frame (10), the extrusion wheel (134) and the rotating wheel (136) are driven to move downward. The friction between the rotating wheel (136) and the supporting pull rod (5) controls the rotation of the rotating wheel (136) and the extrusion wheel (134). During the rotation of the extrusion wheel (134), the mobile guide frame (10) is struck and vibrated, thereby vibrating and cleaning the gravel and debris that may be accumulated on the surface of the mobile guide frame (10); The supporting rods (5) and the positioning rods (7) increase the stability of the retaining wall (1) itself, making the retaining wall (1) itself more ideal in supporting and blocking the slope. The covering net (63) covers the inclined surface of the slope to prevent stones and soil from sliding down at will, and plants can be interspersed between the covering nets (63) to stabilize the soil at the inclined surface of the slope. When it rains, the water flows from top to bottom along the inclined surface of the slope, and the water flows into the movable guide frame (10) and the bearing frame (151) through the water inlet net (16). The bearing frame (151) moves downward as the water increases. The bearing frame (151) slides downward in the movable guide frame (10) and fits on the covering net (63), thereby blocking and guiding the downwardly flowing water, so that the water flows through the movable guide frame (10) into the guide frame (61) and the diversion storage frame (4), thereby preventing the water from impacting the inclined surface of the slope and causing the soil at the inclined surface to flow.
