[0003] In the related art, anti-slide piles are used as supports and applied to the prevention and control of slopes. The anti-slide piles resist the landslide force through the horizontal bearing capacity of the pile foundation. However, the support strength of the anti-slide pile structure in the related art is limited. Utility Model Content

[0006] The multiple first anti-slide piles and the multiple second anti-slide piles are both arranged at intervals along the extension direction of the slope, and the first anti-slide piles and the second anti-slide piles are staggered.

[0007] The pile tops of the second anti-slide piles, the pile tops of two adjacent first anti-slide piles adjacent to the second anti-slide piles, and the pile tops of adjacent first anti-slide piles are all connected by connecting beams, and the connecting beams between the second anti-slide piles and two adjacent first anti-slide piles enclose a triangular area, and a replacement layer is provided in the triangular area.

[0008] In an optional embodiment, the pile distance between two adjacent second anti-slide piles is greater than the pile distance between two adjacent first anti-slide piles.

[0026] Through the above - mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0027] Here, exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0028] In the specification and claims of the present application and the above - mentioned drawings, terms such as "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0029] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific way.

[0030] A slope refers to a ground surface or slope with a certain inclination, which is commonly found in roads, railways, construction sites, and other earthwork or rock - soil sections that require stability. Slopes are usually artificially constructed to ensure the stability of roadbeds or other engineering structures, or are part of the natural terrain.

[0031] Anti - slide piles stand out with their small engineering quantity, wide adaptability and strong anti - slide ability, becoming a preferred solution in slope prevention and control projects. Specifically, anti - slide piles resist landslide forces through the horizontal bearing capacity of the pile foundation, effectively controlling slope sliding.

[0032] In the related art, anti-slide piles are connected by connecting beams to improve the structural strength, but the supporting strength is limited. For example, in the third-phase expansion project of a substation in a power plant, due to the land use conditions and the elevation limits of the first- and second-phase site leveling, the third-phase project is located in a deep backfill area, and the newly built enclosure wall is located at the edge of the slope top. The backfill soil is mainly plain fill, mixed with a small amount of block stones, with an average thickness of 8.04 m. The deep layer is hard plastic silty clay and completely weathered granite. If only a single row or double row of anti-slide piles are set, it is difficult to resist the sliding force of the landslide body, and the foundation of the enclosure wall still needs to be set separately.

[0033] Based on this, the present application provides a slope support structure. Multiple first anti-slide piles inside are connected to multiple second anti-slide piles outside through connecting beams, and a replacement layer is arranged in the triangular area formed by the connecting beams between the second anti-slide pile and two adjacent first anti-slide piles. The connecting beams in the triangular area connect the tops of the inner and outer anti-slide piles into a whole, which is beneficial to improving the structural strength. Moreover, the connecting beams in the triangular area can improve the shear and bending resistance of the anti-slide piles, which is beneficial to dispersing and transmitting the horizontal thrust from the slope. At the same time, the replacement layer can effectively improve the horizontal resistance coefficient and bearing capacity of the soil on the side of the pile top range, effectively limit the sliding of the soil body under the triangular area, and is beneficial to preventing the foundation soil from being extruded. Therefore, the slope support structure provided by the present application effectively improves the support strength and bearing strength, and also facilitates the construction of the subsequent building foundation on the slope.

[0034] The following uses specific embodiments to elaborate in detail on the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application with reference to the drawings.

[0035] Please refer to Figures 1 to 4 , the slope support structure provided by the embodiment of the present application includes multiple first anti-slide piles 10 and multiple second anti-slide piles 20, and the second anti-slide piles 20 are arranged on one side of the first anti-slide piles 10 in the descending direction of the slope.

[0036] The multiple first anti-slide piles 10 and the multiple second anti-slide piles 20 are both arranged at intervals along the extension direction of the slope, and the first anti-slide piles 10 and the second anti-slide piles 20 are arranged in a staggered manner.

[0037] The pile tops of the second anti-slide piles 20, the pile tops of two adjacent first anti-slide piles 10 to the second anti-slide piles 20, and the pile tops of two adjacent first anti-slide piles 10 are all connected by connecting beams 30, and the connecting beams 30 between the second anti-slide piles 20 and two adjacent first anti-slide piles 10 enclose a triangular area, and a replacement layer 40 is arranged in the triangular area.

[0038] Please refer to Figure 1 , Figure 1Schematic diagram of the usage scenario of the slope support structure provided by the embodiments of the present application.

[0039] It should be noted that the descending direction of the slope is the direction from the slope top to the slope bottom of the slope body 100, that is, the direction of natural sliding or flowing under the action of gravity, which is also the Figure 1 X direction in. The extension direction of the slope is the route direction in which the slope body 100 of the slope extends in space. Specifically, it is the azimuth angle of the intersection line of the slope surface and the horizontal plane, that is, the trend of the slope surface. For example, if a slope extends in the northeast-southwest direction, the northeast-southwest direction is the extension direction of the slope. The extension direction of the slope is the Figure 1 Y direction in.

[0040] It can be understood that the first anti-slide pile 10 and the second anti-slide pile 20 are both anti-slide piles, and both are arranged along the vertical direction, and the vertical direction is shown as the Figure 1 Z direction in. The anti-slide pile has a pile top and a pile bottom (pile end) in the Y direction. The pile top is located at the top end of the anti-slide pile in the vertical direction, and the pile bottom (pile end) is located at the bottom end of the anti-slide pile. The height of the anti-slide pile is the length of the anti-slide pile in the Y direction. The anti-slide pile is cylindrical, and the pile diameter of the anti-slide pile is the outer diameter of the anti-slide pile. The pile spacing is the distance between two adjacent anti-slide piles, that is, the spacing distance between adjacent anti-slide piles.

[0041] Please refer to Figure 1 and Figure 2 , multiple first anti-slide piles 10 form the first layer of protection, which are evenly spaced along the natural extension direction of the slope to directly resist the downward sliding force of the slope. Multiple second anti-slide piles 20 form the second layer of protection, and the second layer of protection is arranged on the side of the first layer of protection in the descending direction of the slope, that is, the second layer of protection is arranged on the X direction side of the first layer of protection, and also adopts an interval arrangement method. By arranging the two layers of pile bodies staggered, a three-dimensional protection system that supports each other is formed, which is beneficial to improving the stability and load-bearing capacity of the entire support structure.

[0042] The pile top of each second anti-slide pile 20 is closely connected to the pile tops of two adjacent first anti-slide piles 10, and between two adjacent first anti-slide piles 10, all are tightly connected by a strong connecting beam 30. The connecting beam 30 is beneficial to enhancing the mechanical connection between the pile bodies, and by forming a stable support framework in the triangular area that can be formed between the second anti-slide pile 20 and two adjacent first anti-slide piles 10, it is beneficial to improving the overall rigidity and anti-slip performance of the structure. Optionally, the connecting beam 30 encloses an isosceles right triangle, and the connecting beam 30 of the isosceles right triangle provides better shear resistance and bending resistance, which is beneficial to dispersing and transmitting the horizontal thrust from the slope.

[0043] Meanwhile, a replacement layer 40 is provided within the triangular region. The replacement layer 40 can effectively increase the lateral soil resistance coefficient and bearing capacity of the pile side within the pile top range, which is conducive to restricting the sliding of the soil mass on the lower side of the triangular region, thereby preventing the foundation soil from being extruded.

[0044] Exemplarily, the replacement layer 40 replaces the original soil with materials having higher strength and better permeability (such as gravel, sand-gravel mixture or improved soil) to enhance the bearing capacity and drainage capacity of this region, thereby effectively reducing soil erosion and the occurrence of landslides caused by soil saturation due to water accumulation. The anti-slide piles are precast reinforced concrete piles or cast-in-place bored reinforced concrete piles. The concrete strength grade is determined by the above pile foundation types. The concrete strength of the precast reinforced concrete piles is not less than C80, and the concrete strength of the cast-in-place bored reinforced concrete piles is not less than C30. The pile length is determined by the thickness of the backfill soil layer and the geology. The pile tip is inserted into the old soil layer or bedrock layer by not less than 2m to provide sufficient resistance.

[0045] Optionally, there are two first anti-slide piles 10 between two adjacent second anti-slide piles 20. For the two first anti-slide piles 10 inserted between each pair of second anti-slide piles 20, the second anti-slide piles 20 not only serve as vertical supports, but also form a continuous and grid-like structural system with the surrounding piles through the connecting beam 30 at the top, strengthening the connection between the inner and outer row of piles, and helping to improve the overall coordination and stability of the entire slope support structure. In addition, this layout enhances the resistance of the intermediate region between adjacent pile foundations. Especially for those complex geological conditions where the potential sliding surface may pass under the first row of anti-slide piles, it can more effectively control the movement of the landslide mass.

[0046] Therefore, the slope support structure proposed in the embodiment of the present application, through the staggered arrangement of the double-layer anti-slide piles, connecting the pile tops of the anti-slide piles through the connecting beam 30, and arranging the replacement layer 40 in the triangular region formed by the connecting beam 30, effectively improves the reinforcement effect of the slope and enhances the slope support strength.

[0047] In an optional embodiment, the pile spacing between two adjacent second anti-slide piles 20 is greater than the pile spacing between two adjacent first anti-slide piles 10. By increasing the distance between the second anti-slide piles 20, the earth pressure and sliding force can be more reasonably distributed, ensuring that each pile can exert its maximum effect without overloading, which helps to balance the stress state of the entire support system, reduce the risk of local overload, and enhance the long-term stability and safety of the system.

[0048] In an optional embodiment, the pile spacing between two adjacent first anti-slide piles 10 is 3 to 5 times the pile diameter of the first anti-slide pile 10, and the pile spacing between two adjacent second anti-slide piles 20 is 1.5 to 2.5 times the pile spacing between two adjacent first anti-slide piles 10.

[0049] Set the pile spacing between the first anti-slide piles 10 to 3 to 5 times the pile diameter, which can effectively utilize the structural strength of the piles and meet the minimization of production costs. On the one hand, the pile spacing should not be too small to avoid mutual interference between adjacent piles and ensure that each anti-slide pile can fully exert its bearing potential and effectively utilize the anti-pulling and anti-shearing capacities of the piles. On the other hand, the pile spacing should not be too large, so as not to cause a single pile to bear too wide a soil range, resulting in an overloaded pile or the need to increase the pile diameter to meet the bearing requirements, thereby increasing costs.

[0050] Set the pile spacing of the second anti-slide piles 20 to 1.5 to 2.5 times the pile spacing between adjacent first anti-slide piles 10. When the second anti-slide piles 20 are located deeper in the slope, the second anti-slide piles 20 face more complex geological conditions and greater soil thrust. The increased pile spacing helps to disperse the soil pressure, reduce the load borne by a single pile, and at the same time maintain the compactness and economy of the entire support system. In addition, this setting method can also promote the reasonable distribution of internal soil stress and enhance the overall stability of the slope.

[0051] In an alternative embodiment, the spacing between multiple first anti-slide piles 10 and multiple second anti-slide piles 20 is 0.25 to 0.5 times the pile spacing between adjacent two first anti-slide piles 10.

[0052] By controlling the ratio of the spacing of the second anti-slide piles 20 to the spacing of the first anti-slide piles 10, the stress in the soil can be better adjusted and dispersed, reducing local high-stress concentration, preventing local damage, and enabling the entire support structure to bear external forces more evenly. The arrangement of the second anti-slide piles 20 is deeper or at different horizontal positions than the first anti-slide piles 10. A smaller spacing can form a denser support network, especially suitable for irregular slip surfaces, effectively blocking the sliding soil mass and improving the overall stability of the slope.

[0053] In an alternative embodiment, a receiving platform 50 is provided at the pile tops of both the first anti-slide piles 10 and the second anti-slide piles 20, and adjacent receiving platforms 50 are connected by a connecting beam 30.

[0054] The receiving platform 50 is provided at the top of the anti-slide pile, which is beneficial to improving the horizontal bearing capacity of the anti-slide pile and restricting the pile top displacement.

[0055] Firmly binding adjacent receiving platforms 50 together by the connecting beam 30 forms a continuous and stable support framework, enabling the receiving platforms 50 to more effectively transfer and disperse the loads from above and the sides, reducing local stress concentration, and enhancing the stability of the entire support structure.

[0056] In addition, please refer to Figure 5, the bearing platform 50 also provides a convenient connection platform for subsequent superstructures (such as enclosures, building foundations, or other facilities), eliminating the need for additional conversion structures, simplifying the construction process, and saving costs and time.

[0057] Exemplarily, the connecting beam 30 at the pile top and the bearing platform 50 are made of cast-in-place reinforced concrete, with the concrete strength grade not lower than C30. A 100-mm-thick C20 plain concrete cushion is provided at the bottom of the bearing platform 50, and the edge of the plain concrete cushion extends beyond the bearing platform 50 with an extension length of 100 mm.

[0058] Both the connecting beam 30 and the bearing platform 50 are constructed by cast-in-place reinforced concrete. Reinforced concrete is a widely used building material that combines the high strength of steel bars and the excellent durability of concrete, making it suitable for structural applications under complex stress conditions.

[0059] A 100-mm-thick C20 plain concrete cushion is laid at the bottom of the bearing platform 50, effectively dispersing the load of the bearing platform 50, reducing uneven settlement, and protecting the lower pile body from chemical erosion. The plain concrete cushion has an extension length, which helps to expand the bottom area of the bearing platform 50, increase the contact area with the foundation, and further enhance the overall stability.

[0060] In an alternative embodiment, the top surface of the bearing platform 50 is flush with the top surface of the connecting beam 30.

[0061] In this embodiment, the flat top surface simplifies the construction process of the superstructure and is conducive to improving construction efficiency. Moreover, the smooth transition from the bearing platform 50 to the connecting beam 30 enhances the continuity and unity of the overall structure, is conducive to the uniform distribution of forces, reduces stress concentration points, and improves the stability and durability of the structure.

[0062] In addition, since the top of the anti-slide pile is a flat surface, it is convenient for the construction of the top of the slope support structure.

[0063] In an alternative embodiment, at least part of the pile top of the first anti-slide pile 10 is connected to the bearing platform 50, and at least part of the pile top of the second anti-slide pile 20 is connected to the bearing platform 50.

[0064] By directly connecting at least part of the pile tops of the first anti-slide pile 10 and the second anti-slide pile 20 to the bearing platform 50, additional lateral support can be provided for the pile body, especially in areas with relatively large local sliding forces. In this way, it is beneficial to prevent the pile body from shifting or being damaged due to excessive lateral forces.

[0065] At the same time, the direct connection between the pile top and the bearing platform 50 helps to transfer the forces borne by the pile body more directly and evenly to the connecting beam 30 and the entire support system, reducing the stress concentration phenomenon, making the force distribution more reasonable, and improving the stability and reliability of the entire structure.

[0066] In an alternative embodiment, the receiving platform is circular, and the outer diameter of the receiving platform 50 is 1 to 1.5 times the pile diameter of the first anti-slide pile 10.

[0067] Receiving platforms 50 with different areas can share and transfer different loads. Increasing the outer diameter of the receiving platform 50 can increase the contact area between the receiving platform 50 and the soil, thereby providing greater resistance to resist the sliding force and preventing the slope from sliding down. An overly large receiving platform 50 will increase the consumption of concrete and steel bars, while an overly small one may not be sufficient to provide enough stability. Designing the outer diameter of the receiving platform 50 to be 1 to 1.5 times the pile diameter of the first anti-slide pile 10 can ensure structural safety without causing the project cost to be too high.

[0068] Optionally, the outer diameter of the receiving platform 50 is 1 time, 1.25 times or 1.5 times the pile diameter of the first anti-slide pile 10. If the receiving platform 50 is square or rectangular, then

[0069] In an alternative embodiment, the connecting beam 30 is a cast-in-place beam.

[0070] The cast-in-place beam is directly cast with concrete on-site and can form an integral cast continuous structure with the receiving platform 50 at the top of the pile. This seamless connection greatly enhances the integrity and stability of the structure, reduces the weak links at the connection points, and improves the durability and disaster resistance of the structure.

[0071] Moreover, by setting the connecting beam 30 in the way of on-site casting, the transportation and hoisting costs of prefabricated components are reduced, especially at construction sites in remote areas or with inconvenient transportation.

[0072] In an alternative embodiment, the replacement layer 40 is a rubble concrete layer or a plain concrete layer.

[0073] By adding an appropriate amount of rubble as the aggregate, the rubble concrete not only improves the strength of the concrete but also increases the density and compressive performance of the structure. The gaps between the rubbles in the rubble concrete layer can also serve as drainage channels, which helps to drain accumulated water and reduce the negative impact of water on the slope stability.

[0074] Although the plain concrete layer does not contain aggregate, it has good homogeneity and strong integrity, and can equally effectively bear the load transmitted from the upper structure. Although the plain concrete layer does not have a natural drainage structure like the rubble concrete layer, appropriate slopes and drainage facilities can be designed to assist in drainage, and it can equally effectively prevent water accumulation.

[0075] Compared with the untreated soil layer, the concrete layer has better weather resistance and corrosion resistance, can effectively resist the erosion of the natural environment, can significantly improve the bearing capacity and stability of the replacement area, and extend the service life of the slope support structure.

[0076] Exemplarily, the specific construction steps of the slope protection structure in the embodiments of the present application are as follows:

[0077] 1. Construction preparation and foundation work

[0078] According to the design drawings, precise measurement and marking are carried out at the construction site to determine the positions and dimensions of the anti-slide piles, the receiving platform 50 and the connecting beam 30, ensuring the accuracy of subsequent construction. Based on the lofting marks, the foundation pits required for the receiving platform 50 are excavated to ensure that the bottom of the pits is flat and meets the design depth and dimension requirements. For manually dug anti-slide piles, the pile holes are dug according to the design depth, and the loose soil in the holes is removed to prepare for the installation of the steel reinforcement cage.

[0079] The steel reinforcement cage is fabricated and installed on the ground or in the pit to ensure that the specifications, quantity and binding quality of the steel bars meet the design requirements. The steel bars are bound in the excavated pit of the receiving platform 50 to establish the steel bar framework of the receiving platform 50, preparing for the subsequent concrete pouring. After the steel bar binding, the formwork is installed to construct a temporary support structure for the concrete pouring of the receiving platform 50 and the connecting beam at the pile top. Then, the necessary steel bar binding work is continued within the formwork to ensure that all steel bar components are correctly connected and fixed.

[0080] 2. Concrete pouring stage

[0081] The pile foundations of the first anti-slide pile 10 and the second anti-slide pile 20 on the inner and outer sides are poured, with the inner and outer sides carried out simultaneously to ensure continuous concrete pouring and avoid cold joints; after the pile foundation pouring is completed, the concrete of the receiving platform 50 and the connecting beam 30 is immediately poured to form a continuous concrete structure; the above process is used as a unit operation and repeated until all the concrete pouring work of the pile foundations, the receiving platform 50 and the connecting beam is completed.

[0082] 3. Curing and formwork removal

[0083] The poured concrete needs to be cured sufficiently to ensure its strength development. The curing includes moisture and heat preservation measures, and the curing time is determined according to the concrete type and environmental conditions. After the concrete reaches sufficient strength, the formwork is removed and the site is cleaned to prepare for the subsequent processes.

[0084] 4. Backfilling and finishing work

[0085] In the excavated area between the completed anti-slide piles, space is created for the placement of backfill materials. Then, the designed backfill layer 40, such as rubble concrete or plain concrete, is poured in the excavated area to enhance the bearing capacity and stability of the area, completing the construction of the entire slope protection structure.

[0086] Other embodiments of the present application will be readily apparent to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include known common general knowledge or conventional technical means in the technical field not disclosed in the present application.
