Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope reinforcement technology, and more specifically, to a composite anchor cable anti-slide pile slope reinforcement device. Background Technology
[0002] With the acceleration of industrialization and urbanization, many slope engineering projects face the risk of geological disasters such as landslides and collapses. Especially in mountainous and hilly areas, due to complex geological conditions and the influence of rainfall, slope instability is often significant, leading to major safety hazards. These geological disasters not only affect people's production and lives but also cause serious damage to the construction and operation of infrastructure. Therefore, slope reinforcement technology has received widespread attention in recent years.
[0003] Existing slope reinforcement technologies mainly include anti-slide pile reinforcement, anchor cable reinforcement, and grouting reinforcement. Anti-slide piles, by vertically setting the pile body, transfer the landslide force to the underlying stable layer, thereby enhancing the stability of the slope. However, traditional anti-slide pile technology has some limitations, especially in special circumstances such as heavy rainfall or earthquakes, where the anti-slide performance of anti-slide piles may not fully meet engineering requirements.
[0004] To improve reinforcement effectiveness, many researchers have recently begun combining anchor cables with anti-slide piles to form composite reinforcement systems. Anchor cables, by obliquely passing through the pile and anchoring to the stable layer, effectively enhance the tensile bearing capacity of the anti-slide pile, increasing the stability and anti-slide force of the reinforcement system. While traditional composite anchor cable anti-slide pile reinforcement technology enhances slope stability by combining anti-slide piles and anchor cables, existing designs often suffer from insufficiently strong connections between the anchor cables and piles, limited bearing capacity, and susceptibility to external forces, leading to unsatisfactory reinforcement results. Furthermore, due to inadequate drainage design in slope reinforcement structures, moisture often accumulates around the anti-slide piles, causing ground loosening or exacerbating soil erosion, thus affecting the reinforcement effect. Utility Model Content
[0005] To address the problems in the background art, this utility model provides an improved composite anchor cable anti-slide pile slope reinforcement device. By optimizing the connection between the anchor cable and the anti-slide pile, enhancing the bearing capacity and drainage design, it significantly improves the reinforcement effect and construction feasibility, and has stronger adaptability.
[0006] Based on a key aspect of this utility model, a composite anchor cable anti-slide pile slope reinforcement device is provided, comprising:
[0007] Anti-slide piles are vertically installed within the sliding surface of the slope, with their bottoms embedded in stable strata.
[0008] An anchor cable assembly includes an anchor cable body, an anchor, and an anchoring section. The anchor cable body passes obliquely through the pile body of the anti-slide pile, the anchoring section extends to a stable stratum, and the anchor is fixed to the outer surface of the anti-slide pile.
[0009] The bearing plate is fixedly connected to the side wall of the anti-slide pile and is located between the anchor and the anti-slide pile. It is used to transmit the tension of the anchor cable.
[0010] Grouting material is injected to wrap the anchoring section and fill the borehole in the stable formation;
[0011] The connecting beam is set laterally between adjacent anti-slide piles, and its two ends are fixedly connected to the pile body of the anti-slide piles respectively;
[0012] The drainage pipe is pre-embedded inside the anti-slide pile, and its outlet end is inclined outward towards the slope.
[0013] The capping beam is set at the top of the anti-slide piles and is rigidly connected to the top of each anti-slide pile.
[0014] This invention combines composite anchor cables with anti-slide piles, providing strong anti-slide force and support, effectively enhancing slope stability. The design of the anchor cable assembly obliquely passing through the anti-slide piles can rationally distribute the stress on the slope, ensuring the slope remains stable under various natural conditions. Grouting the anchoring section further improves the anchoring force and the bond strength between the soil and the pile. Furthermore, the installation of drainage pipes effectively prevents soil erosion and water accumulation, ensuring the long-term stability of the structure.
[0015] In some embodiments, as a further preferred embodiment, the angle between the anchor cable body and the axis of the anti-slide pile is 15°-45°, and a pre-embedded sleeve is provided where the anchor cable body passes through the anti-slide pile, with elastic sealing material injected inside the sleeve. By setting the angle between the anchor cable body and the axis of the anti-slide pile to 15°-45°, the tensile strength of the anchor cable can be maximized, enhancing the reinforcement effect. The use of the pre-embedded sleeve and elastic sealing material effectively prevents moisture from penetrating into the pile body, preventing corrosion or loosening at the connection between the anchor cable and the pile body, thereby extending the service life of the reinforcement device.
[0016] In some embodiments, as a further preferred option, the bearing plate is an arc-shaped steel plate whose inner surface conforms to the outer contour of the anti-slip pile and is double-fixed by high-strength bolts and welding. This design enhances the stability of the bearing plate when transmitting anchor cable tension, prevents deformation or loosening of the bearing plate, and ensures the long-term effectiveness of the reinforcement device.
[0017] In some embodiments, as a further preferred option, the grouting body is formed by pressure grouting, and a steel reinforcement cage is pre-embedded inside. The steel reinforcement cage is connected to the anchorage section via a snap-fit structure. The pressure grouting technology creates a tighter bond between the grouting body and the stratum, improving the stability of the anchorage section. The pre-embedded steel reinforcement cage within the grouting body enhances its compressive strength and, through the snap-fit structure, ensures the overall strength and anti-slip capability of the structure.
[0018] In some embodiments, as a further preferred embodiment, the connecting beam is a reinforced concrete structure, with its internal main reinforcement bars connected to the main reinforcement bars of the anti-slide piles by welding. As a reinforced concrete structure, the welding connection between the connecting beam and the anti-slide piles enhances the linkage between them and increases the lateral stability of the reinforcement device. This design effectively prevents adjacent anti-slide piles from shifting or settling unevenly due to external forces.
[0019] In some embodiments, as a further preferred option, the outlet end of the drain pipe is provided with a filter cover, the filter cover being filled with a layer of graded crushed stone. This design prevents the drain pipe from becoming clogged, avoids water accumulation damaging the pile and surrounding soil, and ensures the stability of the reinforcement system.
[0020] In some embodiments, as a further preferred embodiment, the capping beam has an inverted T-shaped cross-section, with its bottom extension embedded in the surface soil of the slope. The capping beam contains a cross-bracing mesh connected to the main reinforcement of the anti-slide piles. The inverted T-shaped cross-section design of the capping beam allows the bottom extension to effectively embed into the surface soil of the slope, thereby enhancing the stability of the slope surface. The connection between the cross-bracing mesh inside the capping beam and the main reinforcement of the anti-slide piles strengthens the integrity of the capping beam and the anti-slide piles, ensuring the stability of the reinforcement system under external forces.
[0021] Advantages and beneficial effects of this utility model:
[0022] This utility model's composite anchor cable anti-slide pile slope reinforcement device effectively improves slope stability and anti-slide capacity by combining the design of anti-slide piles and anchor cables. The combined effect of the obliquely positioned anchor cables and anti-slide piles more evenly distributes the stress generated by slope slippage, improving the reinforcement effect, and demonstrating good adaptability, especially in unstable strata and complex geological conditions.
[0023] This invention further optimizes the connection structure by employing pre-embedded sleeves and elastic sealing materials, making the connection between the anchor cable and the anti-slip pile more secure, effectively preventing water penetration and anchor cable loosening, and extending the service life of the reinforcement device. Furthermore, the pre-embedded steel reinforcement skeleton inside the grouting body enhances the compressive strength of the anchoring section, ensuring the long-term stability of the reinforcement effect.
[0024] Furthermore, the construction process of this device is simple, reducing the complex operational steps of traditional reinforcement methods and lowering construction costs and time. At the same time, the design of the drainage pipe and capping beam effectively solves the problems of soil erosion and water accumulation, further improving the reliability of the reinforcement device under different climatic and environmental conditions, and demonstrating good economic benefits and application prospects.

It should be understood that the following embodiments are not intended to limit the scope of this utility model, but are merely illustrative of its essential spirit.
[0030] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.
[0031] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.
[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0033] Example:
[0034] like Figure 1 , Figure 2 As shown, the composite anchor cable anti-slide pile slope reinforcement device of this utility model is mainly composed of anti-slide pile 1, anchor cable assembly 2, bearing plate 3, grouting body 4, connecting beam 5, drainage pipe 6 and cap beam 7. The components work together to form a composite anti-slide system.
[0035] Anti-slide pile 1 is vertically embedded in the stable stratum below the sliding surface of slope 18, with pre-embedded longitudinal main reinforcement and stirrups inside. A through hole is obliquely opened in the middle of the pile body, with a pre-embedded sleeve 8 inside. The pile tops are connected as a whole by a capping beam 7, which has an inverted T-shaped cross-section. The bottom extension 16 is embedded in the surface soil of slope 18 to increase the overall stability of slope 18. The capping beam 7 contains a cross-shaped steel mesh 17 connected to the main reinforcement of anti-slide pile 1, forming a stable connection and enhancing the overall tensile bearing capacity of anti-slide pile 1. The piles are laterally connected by a connecting beam 5, with the main reinforcement 13 inside the connecting beam 5 welded to the main reinforcement 14 of the anti-slide pile 1 at both ends, forming lateral stability. Anchor cable assembly 2 obliquely penetrates the anti-slide pile 1, providing additional stability by counteracting the sliding force through the anti-slide pile 1.
[0036] An anchor cable body 201 passes through a pre-embedded sleeve 8 at the location where it passes through the anti-slide pile 1, and elastic sealing material 9 is injected into the sleeve to ensure the seal between the anchor cable and the pile body. The anchor 202 is fixed to the outside of the anti-slide pile 1, connects to the anchor cable body 201, and can evenly transmit the tension to the anti-slide pile 1.
[0037] Anchoring section 203 is bonded to the stable stratum through grouting body 4, forming an anchor-pile joint force system. Anti-slide pile 1 provides vertical shear bearing capacity, and anchor cable assembly 2 constrains pile deformation through oblique tension, forming a two-way reinforcement mechanism of "anti-slide pile 1 bearing pressure + anchor cable tension".
[0038] The grouting body 4 is applied to the borehole in the stable stratum using pressure grouting to form a dense connection. A steel reinforcement cage 11 is pre-embedded in the grouting body 4, and the steel reinforcement cage 11 is connected to the anchoring section 203 through a snap-fit structure 12 to enhance the tensile strength of the entire structure.
[0039] like Figure 2 As shown, the drainage pipe 6 is pre-embedded within the pile body of the anti-slide pile 1, with its outlet end inclined towards the outside of the slope 18. A filter cover 15 is installed to drain groundwater, reduce pore water pressure in the soil, and prevent hydraulic seepage damage. The filter cover 15 is filled with a layer of graded crushed stone to prevent soil blockage of the pipe and ensure smooth water discharge. The bearing plate 3 is made of arc-shaped steel plate and is fixed to the side wall of the anti-slide pile 1 by high-strength bolts 10 and welding. Its inner surface is tightly fitted with the outer contour of the anti-slide pile 1 to transfer the tension of the anchor cable to the anti-slide pile 1 and enhance its stability.
[0040] During the specific construction of this utility model device:
[0041] Construction of anti-slide pile 1
[0042] Mark the positions of anti-slide piles 1 according to the design spacing, drill holes below the stable stratum, tie the reinforcing cage of anti-slide pile 1, and pre-embed the drainage pipe 6 and anchor cable sleeve, ensuring that the outlet end of the drainage pipe 6 is inclined outward and the inclination angle of the sleeve is consistent with the design inclination angle of the anchor cable. Fix the filter cover 15 at the inlet end of the drainage pipe 6 and wrap the outside with a layer of graded crushed stone. Pour the concrete for anti-slide pile 1, vibrate it to compact it, and cure it to the design strength.
[0043] Anchor cable assembly 2 installation and grouting,
[0044] Drill a hole at an angle from the pre-embedded sleeve 8 of the anti-slide pile 1 to the designed depth of the stable stratum, insert the anchor cable body 201 into the borehole, and extend the anchoring section 203 to the bottom of the hole; inject cement grout into the borehole through the grouting pipe to form a grouting body 4 that wraps the anchoring section 203. At the same time as grouting, a steel reinforcement skeleton 11 is pre-embedded and connected to the anchor cable body 201 through the snap-fit structure 12.
[0045] After the grouting body 4 reaches its strength, the anchor cable body 201 is prestressed using tensioning equipment and locked to the surface of the bearing plate 3 by the anchor 202.
[0046] Construction of bearing plate 3 and connecting structure.
[0047] The arc-shaped bearing plate 3 is attached to the outer surface of the anti-slide pile 1 and fixed with high-strength bolts 10, and continuously welded along the edge for reinforcement. Connecting beam 5: A trench is excavated between adjacent anti-slide piles 1, the beam reinforcement is tied, the main reinforcement is welded to the main reinforcement of the anti-slide pile 1, and concrete is poured after formwork is erected; an inverted T-shaped cross-section steel mesh is tied to the top of the pile, the intersecting steel mesh 17 is welded to the main reinforcement at the top of the pile, concrete is poured and cured.
[0048] Drain pipe 6: Commissioning and acceptance.
[0049] Remove the soil around the filter cover 15, check the compaction of the graded crushed stone layer to ensure there is no blockage; simulate groundwater conditions to verify the drainage efficiency and anti-clogging performance of the drain pipe 6.
[0050] Implementation effect verification
[0051] The anti-slip stability and long-term reliability of the device were verified through displacement monitoring, anchor cable prestress testing, and drainage efficiency evaluation.
[0052] The above process is a typical implementation of this utility model. In actual engineering, it can be flexibly adjusted according to slope conditions, material characteristics and construction environment, but it is still within the scope of the technical solution of this utility model.
[0053] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
