Description

Technical Field

[0001] This utility model relates to the field of landslide prevention and control engineering technology, and in particular to an adjustable flexible anti-slide pile structure. Background Technology

[0002] In landslide prevention and control projects, anti-slide piles are widely used as retaining structures. They resist landslide thrust through their own stiffness and anchoring force, ensuring slope stability. Anti-slide piles are a commonly used retaining structure. However, traditional anti-slide pile structures have the following significant shortcomings, the specific defects of which are as follows:

[0003] Traditional rigid anti-slide piles, due to their fixed stiffness, are difficult to adapt to the dynamic changes in landslide thrust, and are prone to stress concentration leading to pile cracking, deformation and failure. On the other hand, some existing flexible anti-slide piles rely on electrically driven adjustment devices, which are difficult to supply in remote mountainous areas. Furthermore, they also suffer from high operation and maintenance costs and reliability that is greatly affected by the stability of power supply.

[0004] In addition, the impact force generated by the landslide directly acts on the pile body of the existing anti-slide pile, resulting in excessive instantaneous load on the pile body. Although some pile bodies have added simple buffer components, they are mostly single structures with low energy absorption efficiency and are prone to failure due to repeated impacts, making it difficult to cope with continuous loads under complex geological conditions for a long time. Utility Model Content

[0005] This utility model relates to an adjustable flexible anti-slide pile structure. The structure allows for the adjustment of the buffer net and its height, while also enabling the expansion and contraction deformation of the first pile body. Combined with the deformation buffer of the flexible energy-dissipating ring and the honeycomb structure of each net body, the anti-slide pile has both adjustability and flexible energy-dissipating capability. The spiral protrusion and threaded connecting plate enhance the anchoring performance and external connection adaptability of the pile body, respectively. The overall structure can efficiently resist landslide thrust and adapt to complex geological environments.

[0006] This utility model provides an adjustable flexible anti-slide pile structure, specifically including: a first pile body, a second pile body installed above the first pile body, a flexible energy-dissipating ring installed between the first pile body and the second pile body, a first buffer net installed on the inner side of the first pile body, a second buffer net installed on the inner side of the second pile body, a positioning net provided above the second buffer net, a rotating rod rotatably connected to the positioning net installed in the middle of the positioning net, a wrench tightening block provided above the rotating rod, a rotating ring opened above the rotating rod, and a set of threaded connecting plates installed on both sides above the second pile body.

[0007] Furthermore, a set of sliding grooves are opened on both sides of the upper part of the second pile body. The sliding grooves are T-shaped structures. A guide groove is opened on each side of the threaded connecting plate. The threaded connecting plate is installed inside the sliding groove in cooperation with the guide groove. A locking bolt is installed on one side of the threaded connecting plate, and a threaded mounting hole is opened on the other side of the threaded connecting plate.

[0008] Furthermore, a reinforcing mesh is provided at the bottom of the first buffer mesh, and a threaded connecting mesh is provided above the first buffer mesh. A vertical threaded hole is opened in the middle of the threaded connecting mesh, and a vertical threaded rod is inserted into the threaded hole, with the threaded rod and the threaded hole being threadedly connected.

[0009] Furthermore, a universal joint is installed between the rotating rod and the threaded rod. The rotating rod, the universal joint, and the threaded rod cooperate to form an adjustment structure. A through hole is opened at the upper and lower positions of the universal joint.

[0010] Furthermore, a set of honeycomb holes is respectively opened on the basis of the first buffer mesh, the reinforcing mesh, the threaded connection mesh, the second buffer mesh, and the positioning mesh.

[0011] Furthermore, the outer surfaces of the first pile body and the second pile body are each provided with a set of spiral protrusions.

[0012] Furthermore, a set of threaded holes are opened at the edge of the flexible energy dissipation ring, a set of threaded mounting holes are opened at the top of the first pile body, and a set of threaded mounting holes are opened at the bottom of the second pile body. Two sets of connecting bolts distributed vertically are installed between the threaded mounting holes and the threaded holes. A reinforcing mesh is provided inside the flexible energy dissipation ring.

[0013] Furthermore, a set of positioning blocks arranged in a circular array are provided on the inner side of the first pile body and the second pile body, and a set of positioning grooves are opened at the bottom position of the first buffer net and the top position of the second buffer net, with the positioning blocks extending into the interior of the positioning grooves.

[0014] This utility model provides an adjustable flexible anti-slide pile structure, which has the following beneficial effects:

[0015] In this invention, when the landslide thrust acts on the pile, the flexible energy-dissipating ring between the first and second piles first absorbs part of the impact force through its own deformation, while using the internal reinforcing mesh to resist tearing, thus avoiding stress concentration caused by rigid collision of the pile.

[0016] When the pile body is subjected to force, the honeycomb structure of the first and second buffer nets further disperses the energy through the deformation of the hole walls. The multi-directional support characteristics of the honeycomb holes make the stress evenly distributed, reduce local deformation, and the reinforcement net enhances the bearing capacity of the first buffer net and prevents it from being damaged under strong impact.

[0017] If the landslide thrust or soil pressure changes, the height of the first buffer net can be adjusted by rotating the rotating rod: the rotating rod drives the threaded rod to rotate through the universal joint, and the threaded engagement between the threaded rod and the threaded connection net causes the first buffer net to rise or fall, changing the length of the pile and the size of the internal buffer space to adapt to different stress requirements, thus solving the problem of power supply difficulties for electrically driven adjustment devices in remote mountainous areas.

[0018] The spiral protrusions on the outer surfaces of the first and second piles increase the contact area and friction with the soil, forming a spiral interlocking effect under the thrust of the landslide, thus enhancing the pile's resistance to sliding. At the same time, the spiral structure guides the pile to cut into the soil more easily during installation, reducing construction resistance.

[0019] The threaded connecting plate at the top of the second pile can be flexibly adjusted in position through the T-shaped sliding groove to adapt to the connection requirements of different external protection structures. The locking bolts ensure that there is no loosening after connection, forming an overall anti-slip system.

[0020] Through the above mechanism, anti-slide piles achieve the functions of flexible energy dissipation, adjustable buffering and stable anchoring, and can dynamically adapt to changes in landslide thrust, effectively improving the safety and durability of slope treatment.

Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] Example 1: Please refer to Figures 1 to 10 :

[0044] This utility model proposes an adjustable flexible anti-slide pile structure, comprising: a first pile body 1, a second pile body 3 installed above the first pile body 1, and a set of spiral protrusions on the outer surfaces of the first pile body 1 and the second pile body 3, respectively. Specifically, the spiral protrusions increase the contact area and friction between the pile body and the surrounding soil, enhancing the anchoring force of the pile body in the soil and preventing the pile body from sliding under the thrust of a landslide; the spiral structure guides the pile body to be inserted into the soil more smoothly during installation, reducing the resistance to soil penetration; simultaneously, the spiral protrusions disperse the pressure of the soil on the pile body, avoiding excessive local stress that could damage the pile body; a flexible energy-dissipating ring 4 is installed between the first pile body 1 and the second pile body 3, with a set of threaded holes on the edge of the flexible energy-dissipating ring 4, the thread pitch of which is machined according to actual needs; and a set of... A set of threaded mounting holes is opened at the bottom of the second pile body 3. Two sets of connecting bolts are installed between the threaded mounting holes and the threaded holes. After the bolts are installed, the flexible energy dissipation ring 4 completes the flexible connection between the first pile body 1 and the second pile body 3. The flexible energy dissipation ring 4 adopts high-strength materials in the existing technology according to actual needs. The flexible energy dissipation ring 4 has a reinforcing mesh inside. Specifically, the upper and lower distributed connecting bolts ensure that the flexible energy dissipation ring 4 is tightly connected to the first pile body 1 and the second pile body 3, and at the same time provide a certain deformation space for the flexible energy dissipation ring 4; the flexible energy dissipation ring 4 can absorb and dissipate the impact force generated by the landslide, and buffer the relative displacement between the pile bodies through its own deformation to avoid stress concentration caused by rigid connection; the internal reinforcing mesh enhances the tear resistance of the flexible energy dissipation ring 4 and ensures its service life under repeated deformation.

[0045] In this embodiment, a first buffer net 2 is installed on the inner side of the first pile 1, and a second buffer net 5 is installed on the inner side of the second pile 3. A set of honeycomb holes is formed on the basis of the first buffer net 2, the reinforcing net 201, the threaded connection net 202, the second buffer net 5, and the positioning net 501. Specifically, the honeycomb holes have good energy absorption and dispersion capabilities; when a landslide occurs, the honeycomb energy-dissipating core layer of the first buffer net 2 and the second buffer net 5 can absorb and disperse some of the energy, reducing the impact and damage to the first pile 1 and the second pile 3, effectively improving... To enhance the deformation resistance and stability of the high-resistance-slide piles, a set of positioning blocks arranged in a circular array are respectively installed on the inner side of the first pile body 1 and the second pile body 3. A set of positioning grooves are respectively opened at the bottom of the first buffer net 2 and the top of the second buffer net 5. The positioning blocks extend into the interior of the positioning grooves. Specifically, the positioning blocks cooperate with the positioning grooves to achieve precise positioning of the first buffer net 2 and the second buffer net 5 within the pile body, preventing them from shifting or rotating during stress or adjustment. The circular array of positioning blocks ensures uniform stress on the net body, ensuring the effective functioning of the buffer.

[0046] In this embodiment, a positioning net 501 is provided above the second buffer net 5. A rotating rod 601 is installed in the middle of the positioning net 501. A wrench-tightening block is provided above the rotating rod 601. A rotating ring is formed above the rotating rod 601. Referring to the prior art, an upper and lower positioning structure is set at the position of the rotating ring. A positioning bolt can be installed, or a positioning ring can be set on the rotating ring to position the rotating rod 601 vertically. A reinforcing net 201 is provided at the bottom of the first buffer net 2. A threaded connecting net 202 is provided above the first buffer net 2. The middle of the threaded connecting net 202... A vertical threaded hole is opened at the location, and a vertical threaded rod 603 is inserted into the threaded hole. The threaded rod 603 is threadedly connected to the threaded hole. The thread pitch is processed according to actual needs. Specifically, the reinforcing mesh 201 enhances the overall structural strength of the first buffer mesh 2, preventing it from deforming or being damaged under stress. The threaded connection mesh 202 and the threaded rod 603 are threadedly engaged, and the height position of the first buffer mesh 2 can be adjusted by rotating the threaded rod 603, thereby adjusting the buffer space inside the pile body. At the same time, it realizes the expansion and contraction deformation of the first pile body 1 to adapt to different stress buffering needs. The thread pitch design can control the adjustment accuracy and meet the requirements of fine adjustment.

[0047] In this embodiment, a universal joint 602 is installed between the rotating rod 601 and the threaded rod 603. The rotating rod 601, universal joint 602, and threaded rod 603 cooperate to form the adjustment structure 6. A through hole is opened at the upper and lower positions of the universal joint 602. Matching pins are installed at the positions of the through holes according to actual needs. After the pins are installed, the universal positioning of the threaded rod 603 is completed. Specifically, the universal joint 602 allows the rotating rod 601 and the threaded rod 603 to rotate relative to each other at multiple angles, so that the rotating rod 601 can effectively drive the threaded rod 603 to rotate when operating in different directions, thereby improving the flexibility of the adjustment operation.

[0048] In this embodiment, a set of threaded connecting plates 7 are installed on both sides of the upper position of the second pile body 3. A set of sliding grooves with T-shaped structures are opened on both sides of the upper position of the second pile body 3. A guide groove is opened on each side of the threaded connecting plate 7. The threaded connecting plate 7 is installed inside the sliding groove in cooperation with the guide groove. A locking bolt is installed on one side of the threaded connecting plate 7, and a threaded mounting hole is opened on the other side of the threaded connecting plate 7. Specifically, the T-shaped sliding groove and the guide groove cooperate to realize the stable sliding adjustment of the threaded connecting plate 7. The position of the threaded mounting hole can be flexibly adjusted according to the position of the external connecting components, improving the compatibility of the device with the external structure. The locking bolt can fix the threaded connecting plate 7 after adjustment to prevent it from loosening, ensure the connection strength, and meet the installation requirements under different working conditions.

[0051] Example 4, based on Example 1, such as Figures 2-5 As shown, the bottom of the first pile 1 is sealed according to actual needs.

[0052] The working principle of this embodiment:

[0053] First, prefabricate the first pile body 1 and the second pile body 3 according to the design parameters; prefabricate the first buffer net 2 and the second buffer net 5 with honeycomb holes, as well as the matching reinforcement net 201, threaded connection net 202, and positioning net 501; prepare the flexible energy dissipation ring 4, the adjustment structure 6, and the threaded connection plate 7.

[0054] The first buffer net 2 is installed by cooperating with the positioning block inside the first pile body 1 through the bottom positioning groove, ensuring that the reinforcing net 201 fits the inside of the first pile body 1, so that the threaded rod 603 passes through the threaded hole of the threaded connection net 202.

[0055] The flexible energy dissipation ring 4 is fixed between the first pile body 1 and the second pile body 3 using connecting bolts distributed vertically. The second buffer net 5 is installed by cooperating with the positioning block inside the second pile body 3 through the positioning groove. At the same time, the positioning net 501 is installed. The rotating rod 601 is positioned by passing through the rotating hole in the middle of the positioning net 501. Positioning bolts or positioning rings are installed to limit the vertical displacement of the rotating rod 601.

[0056] The assembled anti-slide piles are guided into or pressed into the preset pile holes by spiral protrusions. The spiral protrusions are tightly engaged with the soil to enhance the anchoring force. If the bottom of the first pile 1 needs to be sealed, the sealing treatment is carried out according to Example 4. According to the installation position of the external structure, the threaded connecting plate 7 on the top of the second pile 3 is slid and adjusted to the appropriate position and then fixed with locking bolts. The connection between the second pile 3 and the external structure is completed through the threaded installation hole.

[0057] By using a tool to rotate the wrench of the rotating rod 601, the threaded rod 603 is driven to rotate through the universal joint 602. The height of the first buffer net 2 is adjusted by the threaded engagement of the threaded connection net 202, and at the same time, the first pile body 1 is expanded and deformed until the internal buffer space of the pile body meets the design requirements.
