Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a slope-fixing column to prevent slope slippage. Background Technology

[0002] Landslides are geological hazards caused by soil and rock masses on a mountain slope sliding downhill along a certain weak surface or zone, either as a whole or in a scattered manner, under the influence of factors such as gravity, groundwater activity, earthquakes, heavy rainfall, and weathering erosion. This results in the destruction of the internal structure of the soil and rock mass, a reduction in shear strength, and an imbalance in the original equilibrium state. Landslides often cause serious damage and threats to transportation, buildings, farmland, life and property safety, and the ecological environment. Therefore, it is necessary to set up protective structures to protect the slope.

[0003] In existing technologies, slope-fixing columns are often used for landslide protection. However, after long-term exposure to wind, sun, and rain, the soil on the slope will become loose, which can easily cause the slope-fixing columns to slide, become unstable, and tilt, thus reducing the protective performance of the slope-fixing columns. Therefore, a slope-fixing column to prevent slope sliding has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slope-fixing column to prevent slope slippage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slope-fixing column for preventing slope slippage includes an outer cylinder and an inner cylinder. The inner cylinder is slidably connected to the bottom of the inner side of the outer cylinder. Both sides of the inner cylinder's sidewall near the top are fixedly connected with protruding strips. Both sides of the outer cylinder's inner circumference have grooves adapted to the protruding strips. A connecting plate is fixedly connected to the middle of the inner side of the inner cylinder. A threaded rod is screwed into the middle of the connecting plate. A screw nut adapted to the threaded rod is fixedly sleeved in the middle of the connecting plate. A connecting column is rotatably connected to the bottom of the threaded rod, and a connecting rod is fixedly connected to the bottom of the connecting column. Three discs are fixedly connected at equal intervals on the circumference of the connecting rod. Three inclined blocks are fixedly connected at equal intervals on the top edge of each disc. Each inclined block has an inclined hole. An insertion hole is opened on the circumference of the inner cylinder near each inclined block. An L-shaped locking block is slidably inserted into each insertion hole. A U-shaped rod is fixedly connected to the bottom of each L-shaped locking block, and the middle of each U-shaped rod is slidably connected to adjacent inclined holes.

[0007] As a further embodiment of this utility model, a fixing rod is slidably fitted at the top of each L-shaped block, and a round hole adapted to the fixing rod is opened at the top of each L-shaped block. One end of the fixing rod is fixedly connected to the inner side wall of the inner cylinder, and the other end of the fixing rod is fixedly connected to a protrusion. By the rise of the disc, in conjunction with the inclined hole and the U-shaped rod, the L-shaped block can be extended.

[0008] As a further embodiment of this utility model, a top plate is fixedly connected to the top of the inner cylinder, and an external threaded cylinder is fixedly connected to the middle position of the top of the top plate.

[0009] As a further embodiment of this utility model, an internally threaded cylinder is rotatably sleeved at the middle of the top of the outer cylinder. A circular hole adapted to the internally threaded cylinder is opened in the middle of the outer cylinder, and the internally threaded cylinder is screwed to the externally threaded cylinder. A hexagonal nut is fixedly connected to the outer circumferential wall of the internally threaded cylinder at the top of the outer cylinder. By rotating the hexagonal nut, the internally threaded cylinder is driven to rotate, so that the outer cylinder can be raised and lowered.

[0010] As a further embodiment of this utility model, a square rod is fixedly connected to the top of the threaded rod, and a square sleeve rod is slidably sleeved on the side of the square rod. The cooperation between the square sleeve rod and the square rod allows the threaded rod to rotate by rotating the internal hexagonal nut when the square sleeve rod rises and falls with the outer cylinder, and the top of the square sleeve rod slides through the top plate.

[0011] As a further embodiment of this utility model, a circular hole adapted to the square sleeve rod is provided in the middle of the top plate, and the square sleeve rod is located inside the external threaded cylinder. An internal hexagonal nut is fixedly connected to the top of the square sleeve rod. By rotating the internal hexagonal nut, the square sleeve rod, the square rod and the threaded rod rotate, thereby causing the threaded rod to lift with the connecting rod, etc., so that the L-shaped locking block extends out, and the outer circumferential surface of the internal hexagonal nut is rotatably connected to the inner side of the top of the internal threaded cylinder.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model employs a square sleeve, an internal hexagonal nut, a threaded rod, a connecting rod, a disc, and L-shaped locking blocks. When the slope-fixing column is inserted into the fixing hole, rotating the internal hexagonal nut causes multiple L-shaped locking blocks at the bottom of the inner cylinder to extend from inside the inner cylinder, ensuring a tight fixation between the slope-fixing column and the slope. This effectively solves the problems mentioned in the background technology and achieves the effect of effectively bearing and dispersing the sliding force generated by the upper slope by relying on the friction between the column body and the slope and the pile end resistance, preventing the slope soil from sliding as a whole or in parts, and providing solid mechanical support for slope stability.

[0014] This utility model, through the setting of an internal threaded cylinder, an external threaded cylinder, and a hexagonal nut, allows the length of the fixed slope column to be adjusted by rotating the hexagonal nut, thereby further improving the practicality of the fixed slope column and enhancing its protective function.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-5A slope-fixing column for preventing slope slippage includes an outer cylinder 1 and an inner cylinder 2. The inner cylinder 2 is slidably connected to the bottom of the inner side of the outer cylinder 1. Protruding strips are fixedly connected to both sides of the inner cylinder 2 near the top. Strip grooves 101 adapted to the protruding strips are formed on both sides of the inner circumference of the outer cylinder 1. A connecting plate 5 is fixedly connected to the middle of the inner side of the inner cylinder 2. A threaded rod 304 is screwed into the middle of the connecting plate 5. A screw nut adapted to the threaded rod 304 is fixedly sleeved in the middle of the connecting plate 5. A connecting column 305 is rotatably connected to the bottom of the threaded rod 304, and a connecting rod 3 is fixedly connected to the bottom of the connecting column 305. Three discs are fixedly connected at equal intervals on the circumferential surface of the connecting rod 3. 301. Each disc 301 has three inclined blocks 302 fixedly connected at equal intervals around its top edge. Each inclined block 302 has an inclined hole 303. The inner cylinder 2 has insertion holes near each inclined block 302 along its circumference. Each insertion hole has an L-shaped locking block 401 slidably inserted into it. Each L-shaped locking block 401 has a U-shaped rod 402 fixedly connected to its bottom. The middle part of each U-shaped rod 402 is slidably connected to the adjacent inclined hole 303. Through the cooperation of the inclined hole 303 and the U-shaped rod 402, when the disc 301 rises, it can extend the L-shaped locking block 401, thereby making the slope column more stably fixed to the slope.

[0024] In this embodiment, a fixing rod 4 is slidably sleeved on the top of each L-shaped block 401, and a round hole adapted to the fixing rod 4 is opened on the top of each L-shaped block 401. One end of the fixing rod 4 is fixedly connected to the inner wall of the inner cylinder 2, and the other end of the fixing rod 4 is fixedly connected to a protrusion.

[0025] In this embodiment, a top plate 201 is fixedly connected to the top of the inner cylinder 2, and an external threaded cylinder 7 is fixedly connected to the middle position of the top of the top plate 201.

[0026] In this embodiment, an internally threaded cylinder 8 is rotatably sleeved at the middle of the top of the outer cylinder 1. A circular hole adapted to the internally threaded cylinder 8 is opened in the middle of the outer cylinder 1, and the internally threaded cylinder 8 is screwed to the externally threaded cylinder 7. Through the cooperation between the externally threaded cylinder 7 and the internally threaded cylinder 8, the internally threaded cylinder 8 can rise or fall along the externally threaded cylinder 7 when it rotates, thereby realizing the length adjustment of the fixed slope column. A hexagonal nut 801 is fixedly connected to the outer circumferential wall of the internally threaded cylinder 8 at the top of the outer cylinder 1.

[0027] In this embodiment, a square rod 6 is fixedly connected to the top of the threaded rod 304, and a square sleeve rod 601 is slidably sleeved on the side of the square rod 6. The top of the square sleeve rod 601 slidably passes through the top plate 201. The arrangement of the square rod 6 and the square sleeve rod 601 ensures that when the square sleeve rod 601 rises with the outer cylinder 1, it can always drive the square rod 6 to rotate.

[0028] In this embodiment, a round hole adapted to the square sleeve rod 601 is provided in the middle of the top plate 201, and the square sleeve rod 601 is located inside the external threaded cylinder 7. The top of the square sleeve rod 601 is fixedly connected to the internal hexagonal nut 602. By rotating the internal hexagonal nut 602, the threaded rod 304 rotates synchronously, thereby causing multiple L-shaped locking blocks 401 to extend, making the fixed slope column more stable. The outer circumference of the internal hexagonal nut 602 is rotatably connected to the inner side of the top of the internal threaded cylinder 8.

[0029] Working principle: During use, a fixing hole adapted to the slope column is made on the slope. The slope column is inserted into the fixing hole. By rotating the internal hex nut 602 with a tool, the square sleeve 601 rotates with the square rod 6, which in turn rotates the threaded rod 304. The threaded rod 304 rises along the connecting plate 5. As the threaded rod 304 rises with the connecting rod 3, the inclined blocks 302 at the top of the three discs 301 all rise. With the cooperation of the inclined hole 303 and the U-shaped rod 402, multiple L-shaped locking blocks 401 can move away from the connecting plate 5. One side of rod 3 extends out, allowing each L-shaped locking block 401 to be inserted into the soil of the slope, making the slope-fixing column more stable and integrated with the slope, effectively preventing the slope from sliding down. When it is necessary to adjust the length of the slope-fixing column and improve its protective effect, the hexagonal nut 801 is turned by a tool, causing the inner threaded cylinder 8 to rotate. Under the action of the inner threaded cylinder 8 and the outer threaded cylinder 7, the outer cylinder 1 rises along with the inner threaded cylinder 8. Due to the setting of the strip groove 101 and the convex strip, the outer cylinder 1 will not rotate, but will only rise, thereby increasing the length of the entire slope-fixing column.
