Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to the technical field of slope reinforcement. Background Art

[0002] In traditional slope reinforcement and landslide control projects, anti-slide piles, as a key support structure, play a vital role in enhancing foundation stability and bearing capacity. In recent years, circular anti-slide piles have been favored due to their unique advantages. Especially in projects with tight time and high construction difficulty, mechanically bored circular anti-slide piles have significantly improved construction efficiency and shortened construction period. However, in actual projects, circular anti-slide piles need to be used in combination with anchor cables in certain areas, such as high slopes and earthquake-sensitive areas.

[0003] In the prior art, holes are usually drilled on the anti-slip piles, and anchor end plates are set at predetermined positions of the circular anti-slip piles. Anchor holes are reserved on the anchor end plates, and finally prestress is applied by tensioning the anchor cable and installing the anchor. However, there are potential weaknesses in the connection between the anchor steel plate and the anti-slip piles, which can easily lead to insufficient integrity and stability of the connection parts, and also easily lead to local stress concentration, affecting the bearing capacity and safety of the structure. The connection structure between the anti-slip piles and the anchor cables has problems such as unstable connection and uneven force. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a slope reinforcement structure, which optimizes the connection method between the anti-slide pile body and the anchor cable to achieve more uniform force distribution and improve structural stability, thereby effectively preventing and reducing the risk of landslides.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A slope reinforcement structure comprises an anti-slip pile, an anchor cable and an anchor, wherein the slope comprises a potentially unstable body, and bedrock is below the potentially unstable body; the anti-slip pile is supported on one side of the potentially unstable body of the slope, and the lower end is anchored in the bedrock; an anchor hole is provided on the anti-slip pile; the anti-slip pile comprises an anti-slip pile body with a circular cross-section, an anchor platform formed by concrete casting is provided on the pile head of the anti-slip pile body, and an inclined anchor surface is provided on the anchor platform; one end of the anchor hole passes through the anchor surface, and the other end passes through the anchor platform or the anti-slip pile body at an angle downward; the tensioned end of the anchor cable passes through the anchor hole and is fixed to the anchor surface by the anchor, and the anchor end of the anchor cable is installed at an angle on the bedrock.

[0007] As a further improvement of the above technical solution:

[0008] The center of the cross section of the anchor hole on the anchor surface coincides with the symmetry center line of the anchor surface, and the center axis of the anchor hole also intersects with the center axis of the anti-sliding pile body.

[0009] There are a plurality of anchor holes, and the anchor holes are distributed in parallel and at intervals along the height direction of the anti-slip pile.

[0010] The included angle between the center axis of the anchor hole and the anchor surface is set to α, and α is 90°.

[0011] The angle between the anchoring surface and the central axis of the anti-sliding pile body is set to β, 20°≤β≤40°.

[0012] The anchoring surface faces away from the potentially unstable body.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] The utility model proposes a slope reinforcement structure, in which the anchor platform and the anti-slide pile are integrally cast to form an integrated structure, which enhances the integrity and stability of the connection. The concrete anchor platform can more evenly disperse and transmit the tension of the anchor cable, reduce local stress concentration, and improve the bearing capacity of the overall structure.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Figures 1 to 3An embodiment of a slope reinforcement structure of the utility model is shown. The slope reinforcement structure of this embodiment includes an anti-sliding pile 1, an anchor cable 2 and an anchor 3. The slope includes a potential unstable body 4, and the bedrock 5 is below the potential unstable body 4; the anti-sliding pile 1 is supported on one side of the potential unstable body 4 of the slope, and the lower end is anchored in the bedrock 5; an anchor hole 13 is provided on the anti-sliding pile 1; the anti-sliding pile 1 includes an anti-sliding pile body 11 with a circular cross-section, and an anchor platform 12 formed by concrete casting is provided on the pile head of the anti-sliding pile body 11, and an inclined anchoring surface 121 is provided on the anchor platform 12; one end of the anchor hole 13 passes through the anchoring surface 121, and the other end passes through the anchor platform 12 or the anti-sliding pile body 11 obliquely downward; the tensioning end 22 of the anchor cable 2 passes through the anchor hole 13 and is fixed on the anchoring surface 121 through the anchor 3, and the anchoring end 21 of the anchor cable 2 is obliquely installed on the bedrock 5. In this structure, the setting of the anchor platform 12 provides an inclined anchoring plane for the anchor cable 2, which can effectively disperse the tension of the anchor cable 2, optimize the mechanical properties, improve the connection strength between the anchor cable 2 and the anti-slip pile 1, and improve the stability of the slope reinforcement structure. The anchor platform and the anti-slip pile are integrally cast to form an integrated structure, which enhances the integrity and stability of the connection. The concrete anchor platform can more evenly disperse and transmit the tension of the anchor cable 2, reduce local stress concentration, and improve the bearing capacity of the overall structure.

[0022] In this embodiment, a plurality of anchor holes 13 are provided, and each anchor hole 13 is parallelly and spaced apart along the height direction of the anti-sliding pile 1. With this structure, the incident angle of the anchor cable 2 can be adjusted by adjusting the position of the anchor end 21 on the bedrock 5 or by connecting different anchor holes 13 at the tensioning end 22, which has good flexibility and adaptability.

[0023] In this embodiment, the angle between the central axis of the anchor hole 13 and the anchor surface 121 is set to α, and α is 90°. Through this structure, it is convenient to make the tensioning direction of the anchor cable 2 perpendicular to the anchor surface 121, improve the force transmission effect of the anchor cable 2, and further improve the stability of the slope reinforcement structure.

[0024] In this embodiment, the angle between the anchoring surface 121 and the central axis of the anti-slip pile body 11 is set to β, 20°≤40°. In this structure, the anchoring platform can be cast on the pile head of the anti-slip pile body 11, and the inclination angle of the anchoring surface 121 is designed according to actual needs to achieve the best adjustment range of the incident angle of the anchor cable 2.

[0025] In this embodiment, the center of the cross section of the anchor hole 13 on the anchor surface 121 coincides with the symmetry center line of the anchor surface 121, and the center axis of the anchor hole 13 also passes through the center axis of the anti-slip pile body 11. This structure helps to optimize the force distribution between the anchor system and the anti-slip pile 1, ensure that the anchoring force is evenly distributed in the center of the anti-slip pile 1, reduce stress concentration caused by improper or uneven anchoring, and increase the stability of the anti-slip pile 1 from the risk of further structural damage.

[0026] In this embodiment, the anchoring surface 121 is away from the potentially unstable body. Through this structure, the stress can be better dispersed and the structural stability of the anti-sliding pile 1 can be improved.
