Description

Technical Field

[0001] This invention belongs to the field of slope protection technology, and particularly relates to an anti-slide pile for slope protection. Background Technology

[0002] my country is a mountainous country, and with economic and social development, mining activities in mountainous and hilly areas are increasing. Due to mining activities, the soil on the slopes of mining areas becomes loose, and coupled with my country's abundant annual rainfall, especially in the southern regions, this results in a large amount of groundwater in the slope soil. This groundwater increases landslide thrust and weakens the strength parameters of the soil and rock mass in the sliding zone, easily inducing geological disasters such as landslides, collapses, swelling, or spalling. To prevent these geological disasters, slope stabilization is necessary. Anti-slide piles are a commonly used slope stabilization support structure.

[0003] Although the current anti-slide pile support structure has good bending and shear resistance, it has the following disadvantages: the anchoring of anti-slide piles requires fixing with concrete, the on-site construction process is relatively complicated, the labor intensity is high, and the construction speed is slow. At the same time, after installation, because it relies on its own main structure to insert into the ground for anti-slide, its resistance to collapse is poor. Summary of the Invention

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This invention provides an anti-slide pile for slope protection, such as... Figure 1-5 As shown, the anti-slide piles for slope protection include: anti-slide pile bodies 1 that can be arranged in a row along the toe of the slope, with retaining plates connecting adjacent anti-slide pile bodies 1; multiple insertion holes 2 opened on the anti-slide pile bodies 1, the top of the insertion hole 2 being an insertion port 3 and the bottom being multiple exit ports 4, both the insertion port 3 and the multiple exit ports 4 being inclined outwards; and steel rivets 5 inserted into each of the multiple insertion holes 2, the steel rivets 5 being inserted along the insertion port 3 and exiting along any of the exit ports 4 into the toe of the slope.

[0034] It should be noted that current anti-slide piles can be classified according to materials as wooden piles, steel piles, and reinforced concrete piles; according to the cross-sectional shape of the pile body as circular, tubular, square, rectangular, cross-shaped, H-shaped, box-shaped, trapezoidal, etc.; according to the hole-forming process as driven piles, bored piles, and excavated piles; and according to the construction process as precast piles and cast-in-place piles.

[0035] Taking cast-in-place piles as an example, current anti-slide pile support structures have good bending and shear resistance, but they have the following disadvantages: the anchoring of anti-slide piles requires fixing with concrete, the on-site construction process is relatively complicated, the labor intensity is high, resulting in a slow construction speed. At the same time, after installation, because they rely on their own main structure to insert into the ground for anti-slide, their resistance to collapse is relatively poor.

[0036] In this embodiment, the anti-slide pile body 1 is manufactured according to the manufacturing process of precast piles. During construction, it is installed by excavation. It can be set in a row along the slope toe. Adjacent anti-slide pile bodies 1 are connected by retaining plates to form slope protection. After being buried, it is covered with soil or concrete, with concrete pouring being the best. When using concrete, before the concrete dries, the steel rivet 5 is inserted through the insertion hole 2. The steel rivet 5 is inserted through the insertion port 3 and then passes through the required through port 4 according to the burial depth, so that the tension bars extend around the anti-slide pile body 1, resulting in good stability after the concrete dries.

[0037] In a further preferred embodiment of the present invention, a plurality of assembly ring cavities 6 are provided inside the anti-slide pile body 1. The number of assembly ring cavities 6 is less than the number of through outlets 4, that is: the number of through outlets 4 is N, and the number of assembly ring cavities 6 is N-1.

[0038] In this embodiment, the number of assembly ring cavities 6 does not correspond to the number of through-holes 4. This is because the lowest through-hole 4 is naturally inclined, which can directly guide the steel rivet 5 through without the need for an additional jacking mechanism.

[0039] In a further preferred embodiment of the present invention, the plurality of assembly ring cavities 6 are correspondingly arranged starting from the uppermost through-hole 4, and no assembly ring cavity 6 is provided at the position corresponding to the lowermost through-hole 4.

[0040] In this embodiment, when the steel bar rivet 5 is inserted, the bottommost outlet 4 is naturally provided with a slope, which can directly guide the steel bar rivet 5 through. When the steel bar rivet 5 is inserted through the outlet 4 located in the middle position, the pushing mechanism in the assembly ring cavity 6 pushes and bends the steel bar rivet 5 to make it through.

[0041] In a further preferred embodiment of the present invention, each of the plurality of assembly ring cavities 6 is provided with a pushing mechanism, the pushing mechanism comprising: a pushing cam 7 rotatably disposed in the assembly ring cavity 6; a plurality of pushing plates 8 slidably disposed in the assembly ring cavity 6 and in contact with the pushing cam 7; and a plurality of guide rods 10 slidably disposed in the assembly ring cavity 6 and extending into the plurality of insertion holes 2 respectively. The plurality of guide rods 10 are fixedly connected to the plurality of pushing plates 8 respectively. The guide rods 10 are correspondingly disposed with the insertion outlet 4. A compression spring 9 is provided on one side of the guide rod 10 and is fixedly connected to the pushing plate 8 and the inner wall of the assembly ring cavity 6.

[0042] In this embodiment, during operation, the jacking mechanism inserts the steel bar rivet 5 into a predetermined position, aligning its end with the through-hole 4. Then, the jacking cam 7 rotates, causing the jacking plate 8 to slide, thereby compressing the compression spring 9 and inserting the guide rod 10 into the through-hole 2. The inclined surface of the guide rod 10 forms the guide surface of the steel bar rivet 5, completing the bending. The jacking surfaces of the jacking cam 7 in the multi-layer assembly ring cavity 6 are staggered to avoid mutual interference. Ideally, there are two assembly ring cavities 6, allowing the jacking surfaces of the jacking cam 7 to be staggered.

[0043] In a further preferred embodiment of the present invention, a rotating groove 11 is provided on the top of the anti-slide pile body 1, a connecting screw seat 12 is detachably installed in the rotating groove 11, a long rotating shaft 13 is movably installed in the anti-slide pile body 1, the long rotating shaft 13 is fixedly inserted through multiple pushing cams 7, and the top end of the long rotating shaft 13 is fixedly connected to the bottom of the connecting screw seat 12.

[0044] In this embodiment, when the push cam 7 is rotated, the screw block on the connecting screw seat 12 is connected by a tool, and then the sleeve tool is rotated to make the long rotating shaft 13 rotate, thus driving the push cam 7 to rotate. After rotating to a specific angle, the connecting screw seat 12 is fixed with bolts. At this time, the steel bar rivet 5 is nailed in until the steel bar rivet 5 is fully inserted and the excess part is cut off.

[0045] In a further preferred embodiment of the present invention, a gravity cavity 14 adapted to a long rotating shaft 13 is provided inside the anti-slide pile body 1. A gravity block 15 is movably provided inside the gravity cavity 14. The gravity block 15 and the long rotating shaft 13 are detachably connected. A touch button 19 that can be triggered by the gravity block 15 is provided inside the gravity cavity 14. Specifically, the detachable connection is achieved by providing a rotating groove 16 at the bottom of the gravity block 15. A pendant block 17 is movably installed inside the rotating groove 16. An easy-break rod 18 that movably passes through the gravity block 15 and the long rotating shaft 13 is fixedly installed on the pendant block 17. The top end of the easy-break rod 18 is fixedly connected to a connecting screw seat 12.

[0046] In this embodiment, during use, the long rotating shaft 13 and the flexible rod 18 rotate synchronously without breaking. The flexible rod 18 drives the pendant block 17 to rotate along the rotating groove 16. However, during use, a major landslide may inevitably occur, which may cause the anti-slide pile body 1 to tilt and break. When the anti-slide pile body 1 breaks, the long rotating shaft 13 deforms, and the flexible rod 18 breaks at this time. The lower half of the flexible rod 18 and part of the pendant block 17 fall onto the touch button 19. The touch button 19 is connected to the alarm system, which is preferably connected to the monitoring station so that the landslide situation can be monitored in real time.

[0047] In a further preferred embodiment of the present invention, the top end of the anti-slide pile body 1 is provided with a plurality of sliding grooves 20, and the plurality of sliding grooves 20 are respectively connected to a plurality of insertion ports 3. A locking head rod 21 extending into the insertion port 3 for pushing the steel bar rivet rod 5 is slidably installed in each of the plurality of sliding grooves 20. An adjusting screw 22 threadedly connected to the locking head rod 21 is rotatably installed in each of the plurality of sliding grooves 20. A limiting ring 23 and an operating screw block 24 are fixedly sleeved on the adjusting screw 22.

[0048] In this embodiment, when the rebar rivet 5 is inserted, since the end of the rebar rivet 5 is a straight rod, it is easy to slide downward. At this time, in order to ensure the pulling force, the operating block 24 on the adjusting screw 22 is turned so that the adjusting screw 22 drives the locking head rod 21 to slide out of the slide groove 20 into the insertion port 3, thereby bending the rebar rivet 5 and avoiding the problem of the rebar rivet 5 sliding down.

[0049] In a further preferred embodiment of the present invention, the locking head rod 21 has a pressing arc surface 25 at one end located inside the insertion port 3. The pressing arc surface 25 is adapted to the arc shape of the insertion port 3 for pressing and bending the steel bar rivet rod 5.

[0050] In this embodiment, after the steel bar rivet 5 is bent, it can be fastened into the insertion port 3 and pressed tightly by the top pressing arc surface 25. Combined with the friction of the steel bar rivet 5, it ensures the use of pulling force.

[0051] In a further preferred embodiment of the present invention, a plug cover 26 is detachably installed on the top of the anti-slide pile body 1, a suspended cavity 27 is provided on the anti-slide pile body 1, a suspended box 29 is suspended in the suspended cavity 27 by means of a retaining spring 28, and a vibration sensor 30 is provided in the suspended box 29.

[0052] In this embodiment, after assembly, the end cap 26 is installed to prevent damage by personnel. During use, a small landslide may occur. In order to be notified in time, the anti-slide pile body 1 is affected and vibrates. The suspended box 29, which is suspended by the spring 28, vibrates, which makes the vibration sensor 30 vibrate more, thereby connecting to the monitoring station to trigger an alarm.

[0053] In a further preferred embodiment of the present invention, a back top seat 31 is fixedly installed on the back side of the anti-slide pile body 1, and a back top column 32 is detachably installed on the back top seat 31, which abuts against the anti-slide pile body 1. The bottom end of the back top column 32 extends into the slope ground and is provided with an assembly seat 33. The assembly seat 33 is detachably connected to the anti-slide pile body 1, and a pad base 34 for balancing the back top column 32 is fixedly installed on the assembly seat 33.

[0054] In this embodiment, the back-top column 32 at the back-top seat 31 of the anti-slide pile body 1 has increased resistance during installation, and the pad base 34 on the mounting base 33 can flatten the back-top column 32.

[0055] In summary, this device uses steel rivet 5 inserted during installation to form multiple tension bars around the anti-slide pile body 1, which can increase stability and improve resistance. The insertion method is also not complicated.

[0056] Compared with related technologies, this device, when used as a whole, is prefabricated and assembled, making on-site operation less labor-intensive than traditional concrete anti-slide piles. Although it is more complex than traditional prefabrication, it has stronger stability and anti-tipping ability during use. The anti-slide pile body 1 has multiple alarm functions, which can alarm when different levels of slippage occur, and can also alarm after damage, making it convenient for people to handle accidents and repair in a timely manner. In terms of monitoring, it is less labor-intensive than traditional manual inspection, and also avoids the problem that manual inspection cannot be carried out in a timely manner.

[0057] It should be noted that during installation, the bottom insertion hole 35 of the anti-slide pile body 1 can be tilted to nail into the temporary insertion rod 36, which facilitates stability during pre-embedding, avoids swaying, and ensures stability after installation.
