Description
Technical Field
[0001] This utility model relates to the technical field of slope anti-slide components, and in particular to an anti-slide pile. Background Technology
[0002] As is well known, anti-slide piles are columnar components that penetrate deep into the soil or rock layers to support the sliding force of the landslide body and stabilize the slope. They are suitable for shallow and medium-thick landslides, and pre-embedding anti-slide piles at the bottom of the slope is a major measure for anti-slide treatment.
[0003] For example, utility model patent application CN215211096U discloses a combined double-row anti-slide pile retaining structure, including a front row of anti-slide piles, a rear row of anti-slide piles, prestressed anchor cables, and connecting beams. The front row of anti-slide piles includes multiple first anti-slide piles that are perpendicular to the ground and equidistantly distributed within the sliding bed. The rear row of anti-slide piles includes multiple second anti-slide piles that are perpendicular to the ground and equidistantly distributed within the sliding bed. The front and rear rows of anti-slide piles are staggered by half a spacing, forming a quincunx-shaped planar arrangement. This quincunx-shaped double-row anti-slide pile and anchor cable combination forms an integrated retaining structure for landslide control, exhibiting strong anti-slide capacity and good stress performance.
[0004] However, the above-mentioned device still has the following drawbacks: the main force exerted by the sliding body on the anti-slide pile is radial shear force. In order to improve the radial bearing capacity of the anti-slide pile, multiple anti-slide piles need to be added or the outer diameter of the anti-slide pile needs to be increased; the sliding body can pass between two adjacent anti-slide piles. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an anti-slide pile that disperses the force of the sliding body, increases the bearing capacity of anti-slide piles of the same diameter to the sliding body, effectively prevents the sliding body from sliding between two anti-slide piles, and further improves the anti-slide effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-slide pile, comprising a sliding bed, a sliding body laid flat on the sliding bed, and a slope bottom connected to the bottom of the sliding bed, and further comprising multiple piles embedded in the slope bottom, corbel seats installed on the piles, and a slope retaining assembly. The corbel seats are provided with a vertical retaining surface and an inclined supporting retaining surface. The slope retaining assembly includes a vertical retaining wall installed on the vertical retaining surface and an inclined supporting retaining wall installed on the inclined supporting retaining surface. Both the vertical retaining wall and the inclined supporting retaining wall are in contact with the bottom of the sliding body, and the bottom of the vertical retaining wall coincides with the ground plane of the slope bottom. The corbel seats on the multiple piles are connected as one unit by the slope retaining assembly. Furthermore, the center of gravity of the corbel seat falls at the central axis of the pile body; the bottom of the corbel seat is flush with the bottom of the vertical retaining wall and also flush with the ground plane of the slope bottom.
[0007] Preferably, the vertical retaining wall is made of porous permeable ceramic wall, and the inclined supporting retaining wall is made of reinforced concrete wall; furthermore, the porous permeable ceramic wall allows water to permeate through and filters and retains soil particles or gravel.
[0008] Preferably, a protective retaining wall is provided at the top of the inclined supporting retaining wall, and the bottom height of the protective retaining wall is higher than the limit height at the contact point between the sliding body and the inclined supporting retaining wall. The protective retaining wall is integrally connected with the inclined supporting retaining wall. Furthermore, both the inclined supporting retaining wall and the protective retaining wall are made of reinforced concrete.
[0009] Preferably, the vertical retaining wall, the inclined supporting retaining wall, and the protective retaining wall are all provided with reinforcing beams on the side away from the sliding body; furthermore, the reinforcing beams are made of reinforced concrete.

[0014] Preferably, the bottom of the bracket is provided with a conical anchor platform.
[0015] Compared with the prior art, this utility model provides an anti-slide pile with the following beneficial effects: This anti-slide pile, through inclined support retaining walls and vertical retaining walls, blocks the sliding body to prevent it from sliding between two adjacent piles. The load force of the sliding body is transmitted to the corbel seat through the inclined support retaining walls and vertical retaining walls. The force transmitted through the vertical retaining walls is mainly converted into a horizontal shear force on the corbel seat, while the force at the inclined support retaining walls is converted into a horizontal shear force on the corbel seat and a vertically downward radial force under the action of the inclined support retaining surface. This part of the force is transmitted to the bottom of the slope and the pile body through the corbel seat, so that the pile body no longer bears a radial shear force in a single direction. The force of the sliding body is dispersed, which improves the bearing capacity of the anti-slide pile of the same diameter size for the sliding body, effectively prevents the sliding body from sliding between two anti-slide piles, and further improves the anti-slide effect.

[0023] As described in the background art, a combined double-row anti-slide pile support structure is used; the main force exerted by the sliding body on the anti-slide pile is radial shear force. In order to improve the radial bearing capacity of the anti-slide pile, multiple anti-slide piles need to be added or the outer diameter of the anti-slide pile needs to be increased; and the sliding body can pass through the space between two adjacent anti-slide piles.
[0024] To solve this technical problem, this utility model provides an anti-slide pile, which is applied to the anti-slide treatment of slopes.
[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] Example 1
[0028] Please refer to Figure 1-2 An anti-slide pile includes: a sliding bed 1, a sliding body 2 laid flat on the sliding bed 1, and a slope bottom 3 connected to the bottom of the sliding bed 1. It also includes multiple piles 4 buried in the slope bottom 3, corbel seats 5 installed on the piles 4, and a slope retaining component. The corbel seats 5 are provided with a vertical retaining surface 6 and an inclined supporting retaining surface 7. The slope retaining component includes a vertical retaining wall 8 installed on the vertical retaining surface 6 and an inclined supporting retaining wall 9 installed on the inclined supporting retaining surface 7. Both the vertical retaining wall 8 and the inclined supporting retaining wall 9 are in contact with the bottom of the sliding body 2. The bottom of the vertical retaining wall 8 coincides with the ground plane of the slope bottom 3. The corbel seats 5 on the multiple piles 4 are connected as one unit by the slope retaining component. Furthermore, the center of gravity of the bracket 5 falls on the central axis of the pile 4; the bottom of the bracket 5 is flush with the bottom of the vertical retaining wall 8 and the ground plane of the slope bottom 3. The bottom of the bracket 5 is placed at the ground plane of the slope bottom 3. The bracket 5 transfers part of the vertical force to the ground plane, and the remaining part of the vertical force acts on the pile 4, effectively reducing the load on the pile 4.
[0029] For details, please refer to Figure 1-2 The vertical retaining wall 8 is made of porous permeable ceramic wall, and the inclined supporting retaining wall 9 is made of reinforced concrete wall; furthermore, the porous permeable ceramic wall allows water to permeate through and filters and retains soil particles or gravel.
[0030] For details, please refer to Figure 5 The bottom of the bracket 5 is provided with a slot 15 that fits with the top of the pile 4, and the top of the pile 4 is inserted into the slot 15.
[0031] Specifically, the top of the pile body 4 is provided with a pile top reinforcement 16, and the bottom of the corbel seat 5 is provided with a sleeve 17 that fits the outer diameter of the top of the pile body 4. Furthermore, the pile body 4 adopts a reinforced concrete structure, the pile top reinforcement 16 adopts a steel sleeve, the steel sleeve is fitted on the top of the pile body 4, and the inner wall of the sleeve 17 is provided with a waterproof structure such as a rubber ring.
[0032] For details, please refer to Figure 1The bottom of the bull leg seat 5 is provided with a conical anchor platform 18.
[0033] The anti-slide pile provided in this embodiment allows rainwater to seep into the sliding body 2 and flow downwards along the sliding bed 1 during rainfall. If rainwater accumulates at the sliding body 2, it will increase the load at the sliding body 2 and the bearing pressure on the bracket 5 and the pile 4. The vertical retaining wall 8 uses a porous permeable ceramic wall, which allows rainwater to seep out through the porous permeable ceramic wall while ensuring structural strength, thereby reducing the water content in the sliding body 2, thus reducing the load on the bracket 5 and the pile 4 and lowering the incidence of landslide accidents caused by rainwater. The bracket 5 and the pile 4 are connected by a socket at the top, improving the ease of assembly. The bracket 5 can be prefabricated, thereby effectively shortening the time required for assembly. Construction period; the pile top reinforcement 16 can effectively protect the top of the pile body 4, preventing the top of the pile body 4 from being damaged during the assembly process of the pile body 4 and the corbel seat 5, while the sleeve 17 can further improve the connection strength between the pile body 4 and the corbel seat 5, thereby improving the connection stability between the pile body 4 and the corbel seat 5 and allowing the load at the corbel seat 5 to be smoothly transferred to the pile body 4; the conical anchor 18 can increase the friction between the corbel seat 5 and the ground plane at the bottom of the slope 3, and the horizontal load thrust at the corbel seat 5 is transferred to the ground through the conical anchor 18, using the weight of the corbel seat 5 itself and the frictional resistance between the corbel seat 5 and the ground plane at the bottom of the slope 3 to offset the horizontal load thrust.
[0034] Example 2
[0035] The anti-slide pile provided in Example 1 has been further optimized. For details, please refer to [link / reference needed]. Figure 1 or Figure 2 The inclined support retaining wall 9 is equipped with a protective retaining wall 10 at its top. The bottom height of the protective retaining wall 10 is higher than the limit height at the contact point between the sliding body 2 and the inclined support retaining wall 9. The protective retaining wall 10 is integrally connected with the inclined support retaining wall 9. Furthermore, both the inclined support retaining wall 9 and the protective retaining wall 10 are made of reinforced concrete.
[0036] For details, please refer to Figure 1 and Figure 2 The vertical retaining wall 8, the inclined supporting retaining wall 9, and the protective retaining wall 10 are all provided with reinforcing beams 11 on the side away from the sliding body 2; furthermore, the reinforcing beams 11 are made of reinforced concrete.
[0037] For details, please refer to Figure 1 The vertical retaining wall 8 and the inclined supporting retaining wall 9 form an angle of 120-150°; furthermore, the angle between the vertical retaining wall 8 and the inclined supporting retaining wall 9 is preferably 135°.
[0038] For details, please refer to Figures 3-4At the junction of the protective retaining wall 10 and the inclined supporting retaining wall 9, a tensioning embedded component is installed. The tensioning embedded component includes an angle iron 12, a pre-embedded bolt 13 fixedly connected to the angle iron 12, and multiple traction rings 14. The multiple traction rings 14 are evenly distributed at the angle iron 12. Furthermore, the pre-embedded bolt 13 is embedded in the protective retaining wall 10 and the inclined supporting retaining wall 9.
[0039] The anti-slide piles and retaining walls 10 provided in this embodiment can block falling rocks and some soil at the landslide site 2, thus preventing harm to people passing below the slope. The reinforcing beams 11 can further improve the structural strength and load limit value of the vertical retaining walls 8, the inclined supporting retaining walls 9, and the protective retaining walls 10, as well as the structural connection strength between them. The 120-150° angle between the vertical retaining walls 8 and the inclined supporting retaining walls 9 can reduce the load force on the landslide site 2. The force is more evenly distributed into horizontal and vertical forces, avoiding excessive differences between the horizontal and vertical forces. The traction ring 14 can provide a point of force for external traction anchors or protective nets, eliminating the need to drill holes in the protective retaining wall 10 or the inclined supporting retaining wall 9, thus improving the ease of installation of external traction anchors or protective nets. When the traction ring 14 is connected to the external traction anchor, the external traction anchor can further distribute the load force of the sliding body 2, further reducing the load force at the corbel seat 5 and the pile body 4.
[0040] The process of using the anti-slide pile provided by this utility model is as follows: The bottom of the sliding body 2 is excavated and temporarily supported. A pile hole is excavated at the bottom of the slope 3. A formwork is installed inside the pile hole, and the pile body 4 is cast. A corbel 5 is installed on top of the pile body 4. Then, the reinforcing beam 11, the inclined support retaining wall 9, and the vertical retaining wall 8 are constructed using formwork and pouring. The vertical retaining wall 8 uses a porous permeable ceramic wall embedded in the reinforced concrete wall, making the reinforcing beam 11, the inclined support retaining wall 9, and the vertical retaining wall 8 integrally connected. The inclined support retaining wall 9 and the vertical retaining wall 8 are connected to the corbel 5 through rebar installation and poured concrete. The supporting retaining wall 9 and the vertical retaining wall 8 block the sliding body 2 to prevent it from sliding down between two adjacent piles 4. The load force of the sliding body 2 is transmitted to the corbel seat 5 through the inclined supporting retaining wall 9 and the vertical retaining wall 8. The force transmitted through the vertical retaining wall 8 is mainly converted into a horizontal shear force on the corbel seat 5, while the force transmitted through the inclined supporting retaining wall 9 is converted into a horizontal shear force and a vertically downward radial force on the corbel seat 5 under the action of the inclined supporting retaining surface 7. This part of the force is transmitted to the bottom of the slope 3 and the pile 4 through the corbel seat 5, thus achieving anti-sliding of the sliding body 2.
