Description

Technical Field

[0001] This invention relates to a composite structure anchored anti-slide pile and slope support system, belonging to the field of slope support technology. Background Technology

[0002] In slope protection engineering, anti-slide piles are key retaining structures that resist the sliding force of landslides and ensure slope stability. In existing technologies, expansive anti-slide piles are used because they provide high anchorage force.

[0003] For example, patent application number 201510227582.1 discloses an "anti-slide pile for slope support," which includes an anchor rod, an outer sleeve fitted onto the anchor rod for deep embedment in the slope, and a tightening device that is threaded to the upper end of the anchor rod and tightly abuts against the upper end face of the outer sleeve. The lower end of the anchor rod is provided with a lower tapered expansion head that widens towards the end. The section of the outer sleeve corresponding to the lower tapered expansion head has at least three longitudinal cuts to form a lower expansion section, which typically expands the lower section of the sleeve through the tapered expansion head, thereby embedding it into the surrounding soil. However, such prior art generally has the following limitations: The anchoring state is irreversible: once the expansion anchor is secured, it is difficult to recover or adjust, which cannot meet the engineering requirements for temporary support or reusable projects, resulting in a waste of resources.

[0004] Limited collaborative working capacity: The pile body mainly relies on its own resistance and has a weak connection with the slope support structure, making it difficult to form an overall force-bearing system and limiting its overall support effectiveness.

[0005] Insufficient adaptability: Under complex geological conditions, its anchoring force is singular and cannot be adjusted, which cannot effectively cope with soil creep or load changes, and its long-term stability faces challenges.

[0006] Therefore, in order to solve the above-mentioned technical problems, there is an urgent need for a composite structure anchored anti-slide pile and slope support system. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composite structure anchored anti-slide pile and slope protection system, which has the advantages of high-efficiency anchoring, adjustability, reusability, and can work in conjunction with the slope protection system to improve the reliability, economy and environmental friendliness of slope protection projects.

Side slots are created on the side wall of the embedded end of the pile body, and each expansion pusher has multiple side slots. Anchor blocks are rotatably installed inside the pile body, corresponding one-to-one with the side slots, and are equipped with elastic structures. The anchor blocks are used to cooperate with the expansion plate. When the expansion plate descends with the adjusting bolt, the anchor blocks are squeezed outward from the side slots by the expansion plate. When the expansion plate rises with the adjusting bolt, the anchor blocks are rotated inward by the elastic structure.

[0009] Furthermore, it also includes positioning grooves, which are formed on the outer periphery of the expansion plate. Each expansion plate has several positioning grooves, and each positioning groove corresponds to an anchor block.

The clamping mechanism is located between the support mechanism and the pressure plate of the composite structure anchored anti-slide pile, and each clamping mechanism corresponds to one composite structure anchored anti-slide pile.

[0015] Furthermore, the clamping mechanism includes a clamping plate, a support ring, a clamping seat, and clamping bolts, wherein, The clamping plate has a through hole for the pile body to pass through, and the support ring is fixed on the side of the clamping plate facing the pressure plate, and the support ring is located on the outside of the pressure plate; Multiple clamping bolts are provided, and the multiple clamping bolts are threadedly installed on the circumference of the pressure plate; The clamping seat is fixed to the end of the clamping bolt facing the clamping plate; Several side support blocks are evenly distributed on the outer side of the support ring, and the side support blocks are fixed to the clamping plate.

[0016] Furthermore, the clamping mechanism also includes a support frame and support bars, wherein, The support frame and support bars are both fixed on the side of the pressure plate facing the pressure plate. There are four support bars, one end of which is connected to the corner of the support frame and the other end is connected to the support ring.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0024] like Figures 1 to 3 As shown, this embodiment provides a composite structure anchored anti-slide pile 3, comprising: The pile body 301 has a hollow structure, and a pressure plate 304 is fixed on the outer periphery of the exposed end of the pile body 301. An adjusting bolt 306 is rotatably installed inside the pile body 301. Several expanding and pushing discs 309 are threaded on the surface of the adjusting bolt 306. When the adjusting bolt 306 rotates, the expanding and pushing discs 309 rise or fall. Side slots 303 are formed on the side wall of the embedded end of the pile body 301, and each expansion pusher 309 has multiple side slots 303. Anchor blocks 312 are rotatably installed inside pile bodies 301, corresponding one-to-one with side slots 303, and are equipped with elastic structures. The anchor blocks 312 are used to cooperate with the expansion plate 309. When the expansion plate 309 descends with the adjusting bolt 306, the anchor blocks 312 are squeezed outward from the side slots 303 by the expansion plate 309. When the expansion plate 309 rises with the adjusting bolt 306, the anchor blocks 312 are rotated inward by the elastic structure.

[0025] In the above technical solution, the side slot 303 provides space for the anchor block 3312 to expand, making it convenient for the anchor block 312 to be expanded. In the unanchored state, the anchor block 312 can be held in the pile body 301 under the action of the elastic structure. A pressure plate 304 is set at the exposed end of the pile body 301 to provide a pressing effect after the pile body 301 is anchored. like Figure 3 As shown, the anchor block 312 is rotatably installed inside the pile body 301 via the rotating seat 311, and the rotating seat 311 is fixed inside the pile body 301; After the pile 301 is anchored into the target slope 101, the expanding plate 309 can be lowered by rotating the adjusting bolt 306. The anchoring block 312 will expand outward under the pressure of the expanding plate 309 to achieve anchoring. When the adjusting bolt 306 is rotated in the opposite direction, the expanding plate 309 will rise accordingly. The anchoring block 312 will no longer be compressed and will reset under the action of the elastic structure so that the pile 301 can be retracted.

[0026] like Figure 3As shown, a soft support pad 314 is also provided on the side of the side slot 303 corresponding to the bottom end of the anchor block 304, so that the anchor block 304 can be buffered and protected during the rotation process by the support pad 314.

[0027] The above-described scheme allows for easy switching of the anchoring state through simple mechanical adjustments, enabling the pile 301 to be easily retrieved and reused. This is particularly suitable for temporary support projects, reducing costs and environmental impact. By controlling the rotation angle of the adjusting bolt 306, the expansion degree of the anchoring block 312 can be precisely controlled, thereby achieving active adjustment of the anchoring force to adapt to different geological conditions. The mechanical expansion structure is stable and reliable, not easily affected by ground creep or chemical corrosion, and exhibits good long-term performance and stability.

[0028] To achieve the fit between the anchor block 312 and the expansion plate 309, such as Figure 2 and Figure 3 As shown, it also includes a positioning groove 310, which is formed on the outer periphery of the expansion plate 309. Each expansion plate 309 is provided with a plurality of positioning grooves 310, and each positioning groove 310 corresponds one-to-one with the anchor block 312. The anchor block 312 is provided with an inclined portion that cooperates with the positioning groove 310. The side of the expansion and pushing plate 309 is an inclined surface or a conical surface. The inclined portion provided on the inner end of the anchor block 312 matches it, so that the downward movement of the expansion and pushing plate 309 can be smoothly converted into the outward rotation of the anchor block 312.

[0029] To improve stability during anchoring, a protrusion 313 is also included. The protrusion 313 is fixed on the anchoring surface of the anchoring block 312, and multiple protrusions 313 are evenly distributed on the anchoring surface of each anchoring block 312.

[0030] like Figure 2 As shown, to drive the adjusting bolt 306, a handwheel 307 and a drill bit 317 are also included, wherein, The handwheel 307 is fixed on one end of the adjusting bolt 306 corresponding to the exposed end of the pile body 301, and the drill bit 317 is fixed on the other end of the adjusting bolt 306. Both the handwheel 307 and the drill bit 317 are located outside the pile body 301. The adjusting bolt 306 can be driven by rotating the handwheel 307, and the location of the drill bit 317 also facilitates the anchoring of the pile body 301 into the slope 101. The top of the handwheel 307 is provided with an adjusting bolt head 308, which has a hexagonal hole so as to cooperate with an internal hex wrench to drive the adjusting bolt 306.

[0031] like Figure 1 and Figure 2 As shown, to enhance the strength of the pile body 301, a top cap 305 and a reinforcing frame 302 are also included. The top cover 305 is fixed on the top of the pile body 301, and the adjusting bolt 306 is rotatably connected to the top cover 305. The top cover 305 is used to realize the rotatable connection between the adjusting bolt 306 and the pile body 301. The reinforcing frame 302 is fixed on the outer wall of the embedded end of the pile body 301. The reinforcing frame 302 can effectively improve the strength of the pile body 301 when it is anchored.

[0032] To achieve the resetting effect of the elastic structure on the anchor block 312, the elastic structure includes a tension spring 315 and a connecting seat 316, wherein, The connecting seat 316 is fixed inside the pile body 301, and one end of the tension spring 315 is fixed to the connecting seat 316, while the other end is fixed to the bottom of the anchor block 312.

[0033] In summary, the composite structure anchored anti-slide pile provided in this embodiment can switch between anchoring states through simple mechanical adjustment, allowing the pile body 301 to be easily retrieved and reused. This is particularly suitable for temporary support projects, reducing costs and environmental impact. By controlling the rotation angle of the adjusting bolt 306, the expansion degree of the anchoring block 312 can be precisely controlled, thereby achieving active adjustment of the anchoring force to adapt to different geological conditions. The mechanical expansion structure is stable and reliable, not easily affected by ground creep or chemical corrosion, and exhibits good long-term performance and stability. Example 2

[0034] like Figure 5 and Figure 6 As shown, this embodiment provides a slope support system, including a support mechanism 2, a clamping mechanism 4, and a composite structure anchored anti-slide pile 3 as described in Embodiment 1. The support mechanism 2 is set on the slope surface of the slope 1, and the composite structure anchored anti-slide pile 3 passes through the support mechanism 2 and is anchored into the slope body 101 of the slope 1. The clamping mechanism 4 is located between the support mechanism 2 and the pressure plate 304 of the composite structure anchored anti-slide pile, and each clamping mechanism 4 corresponds to one composite structure anchored anti-slide pile.

[0035] In the above technical solution, during slope support, the support mechanism 2, the clamping mechanism 4, and the composite structure anchored anti-slide pile 3 provided in Example 1 are used in combination. The support mechanism 2 is placed on the slope surface of the slope 1, and the composite structure anchored anti-slide pile is passed through the support mechanism 2 and anchored into the slope body 101 of the slope 1 to achieve rapid anchoring. At the same time, the composite structure anchored anti-slide pile 3 provided in Example 1, together with the clamping mechanism 4, can effectively ensure the anchoring and anti-slide performance.

[0036] like Figure 1 and Figure 3As shown, to achieve the clamping mechanism 4 and the composite structure anchored anti-slide pile 3 for clamping, the clamping mechanism 4 includes a clamping plate 401, a support ring 406, a clamping seat 407, and a clamping bolt 408, wherein, The clamping plate 401 has a through hole for the pile body 301 to pass through, and the support ring 406 is fixed on the side of the clamping plate 401 facing the pressure plate 304, and the support ring 406 is located on the outside of the pressure plate 304. Multiple clamping bolts 408 are provided, and the multiple clamping bolts 408 are threadedly installed on the circumference of the pressure plate 304; The clamping seat 407 is fixed on the end of the clamping bolt 408 facing the clamping plate 401; Several side support blocks 405 are evenly distributed on the outer side of the support ring 406, and the side support blocks 405 are fixed to the clamping plate 401.

[0037] In the above technical solution, a pressing seat 407 is provided on the surface of the pressing plate 401 and a pressing bolt 408 is connected to it and threadedly distributed on the pressure plate 304. After the anchoring is completed, the pressing seat 407 is pushed to press against the pressing plate 401 by rotating the pressing bolt 408. The pressing plate 401 further presses the plate, which helps to generate a reverse force and thus improves the stability during use.

[0038] The clamping mechanism 4 further includes a support frame 403 and a support bar 404, wherein... The support frame 403 and the support bar 404 are both fixed on the side of the pressure plate 401 facing the pressure plate 304. There are four support bars 404. One end of each support bar 404 is connected to the corner of the support frame 403, and the other end is connected to the support ring 406. A support frame 403 is provided on the clamping plate 401, and a support bar 404 and a support ring 406 are connected on the inner side. This can increase the support strength after tightening and prevent easy deformation, so as to ensure the strength of the anchor during use. At the same time, the side support block 405 improves the side support strength of the support ring 406 and ensures the stability of use.

[0039] like Figure 5 and Figure 6 As shown, the support mechanism 2 includes a support plate 201, vertical reinforcing ribs 202, and horizontal reinforcing ribs 203, wherein, The vertical reinforcing ribs 202 and the horizontal reinforcing ribs 203 are installed on the side of the support plate 201 away from the slope 1, and the vertical reinforcing ribs 202 and the horizontal reinforcing ribs 203 are distributed in a crisscross pattern. The support plate 201 has a through hole 204 for the pile body 301 to pass through; like Figure 1 and Figure 3As shown, the clamping plate 401 has a limiting groove 402 adapted to the transverse reinforcing rib 203 on the side facing the support plate 201. The clamping plate 401 covers the transverse reinforcing rib 203, and the limiting groove 402 is opened at the bottom of the clamping plate 401 to facilitate docking with the transverse reinforcing rib 203, so as to ensure the strength during the anchoring process. The vertical reinforcing rib 202 and the transverse reinforcing rib 203 are distributed on the surface of the support plate 201, which helps to further improve the support strength of the support plate 201 and make the support effect more stable.

[0040] The slope support system provided in this embodiment, when using the composite structure anchored anti-slide pile 3 provided in Embodiment 1 for slope support, can first drill installation holes 102 on the slope 101, and then place the anti-slide pile 3 into the holes. By rotating the handwheel 307, the adjusting bolt 306 is driven to rotate, which drives the expanding and pushing plate 309 to move downward. The expanding and pushing plate 309 squeezes the inner end of the anchor block 312, forcing the anchor block 312 to rotate outward around the rotating seat 311, and finally expands and presses it into the stable soil layer on the side wall of the installation hole 102, completing the anchoring.

[0041] Subsequently, tightening the clamping bolt 408 pushes the clamping plate 401 downward, pressing it against the support plate 201. Through the interaction between the pressure plate 304 and the clamping plate assembly 4, a preload is applied to the entire system, greatly improving the stability of the support.

[0042] When it is necessary to recover the pile 301, the adjusting bolt 306 is rotated in the opposite direction, causing the expanding plate 309 to rise. The anchoring block 312 retracts inward and resets under the tension of the tension spring 315, thus allowing the composite structure anchored anti-slide pile 3 to be removed from the slope for reuse.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
