Description

Technical Field

[0001] This invention relates to the field of anchor bolt support, specifically to an anchor bolt support system and method for high slopes in soft rock. Background Technology

[0002] High slopes in soft rock are widely used in road construction, mining, and water conservancy projects. Due to the low strength and poor stability of the rock and soil, they are susceptible to geological disasters such as landslides and collapses caused by geological conditions, rainfall, and vibration. Therefore, reliable anchor bolt support systems are needed to ensure slope stability. Anchor bolt support, as a commonly used slope reinforcement method, transfers stress through the interaction between the anchor bolt and the rock and soil, inhibiting slope deformation. It is an indispensable protective measure in high soft rock slope engineering.

[0003] Existing anchor bolt support systems for high soft rock slopes have several shortcomings. The surface area of ​​some anchor bolts is fixed, making it impossible to flexibly adjust according to different environmental conditions such as the looseness of the slope soil and rock, and stress requirements. This results in poor contact and stress distribution between the support surface and the soil mass, leading to insufficient support stability. Furthermore, the height and angle adjustment mechanisms of the anchor bolts are poorly designed, the adjustment process is cumbersome, and it is difficult to quickly and accurately adapt to slopes with different gradients. Moreover, the locking structure after adjustment has poor reliability and is prone to loosening under slope vibration or external forces, affecting the support effect. In addition, the various adjustment mechanisms in some support systems have poor interoperability, and the operation process is complex, making it impossible to efficiently adapt the support and meet the complex and variable support needs of high soft rock slopes.

[0014] In this embodiment, two sets of wedge blocks 14 are provided and arranged symmetrically.

Two sets of first reset springs 15 are provided, and the distance between the two sets of first reset springs 15 is greater than the height of the second drive block 111.

[0015] Specifically, the rotating rod 16 is rotatably connected to the middle position of the support plate 11, the first driving block 17 is fixedly set in the middle position of the rotating rod 16, and the first driving block 17 is rotatably set in the middle position of the inner side of the support plate 11.

[0017] It should be noted that rotating the rotating rod 16 causes the first driving block 17 to rotate, the first driving block 17 presses the driven ball 18, pushes the push rod 19 to slide along the connecting shell 112 and compresses the second return spring 110, the second driving block 111 moves with the push rod 19 and slides between the two sets of wedge blocks 14, the first return spring 15 causes the wedge blocks 14 to slide in opposite directions along the limiting fixing groove 13 and the guide groove 113, releasing the limitation on the adjusting sliding plate 12, rotating the rotating rod 16 in the opposite direction, the second return spring 110 drives the push rod 19 and the second driving block 111 to return to their original positions, the second driving block 111 moves with the push rod 19 and presses the two sets of wedge blocks 14 through the inclined surface, causing the wedge blocks 14 to slide to both sides along the limiting fixing groove 13 and the guide groove 113, and the wedge blocks 14 are locked into the corresponding positions of the limiting fixing groove 13.

[0018] Specifically, the height telescopic adjustment unit 2 includes a connecting cylinder 21, a driving thread 22 is provided on the inner side of the connecting cylinder 21, a bidirectional threaded rod 23 is connected to the driving thread 22, a rotating block 24 is provided at the middle position of the bidirectional threaded rod 23, a guide tube 25 is connected to the outer side of the connecting cylinder 21, and a guide slide rod 26 is connected to the inner side of the guide tube 25.

[0019] It should be noted that rotating the rotating block 24 drives the bidirectional threaded rod 23 to rotate. By driving the thread 22 to mesh with the connecting cylinder 21, the two sets of connecting cylinders 21 move closer or further apart along the axial direction of the bidirectional threaded rod 23. The guide slide rod 26 slides along the guide tube 25, restricting the rotation of the connecting cylinder 21.

[0020] In this embodiment, the bidirectional threaded rod 23 is threaded to the inner side of the connecting cylinder 21 through the driving thread 22. The connecting cylinder 21 is provided in two sets and is arranged symmetrically. The top end of one set of connecting cylinders 21 is fixedly located at the lower middle position of the support plate 11. The rotating block 24 is located between the two sets of connecting cylinders 21. The guide slide rod 26 is slidably connected to the inner side of the guide tube 25.

[0021] It should be noted that the connecting plate 32 is connected to the connecting cylinder 21 by bolts 33. Rotating the nut 34 can adjust the relative position of the connecting plate 32 and the connecting cylinder 21, thereby adjusting the angle of the fixed support block 31.

[0022] Specifically, the support adjustment unit 3 includes a fixed support block 31, a coupling plate 32 is provided on the upper side of the fixed support block 31, a bolt 33 is connected to the coupling plate 32, and a nut 34 is provided at both ends of the bolt 33.

[0023] In a preferred embodiment, the fixed support block 31 is a rectangular steel plate made of Q355 carbon steel, with anti-slip texture on the lower surface; the connecting plate 32 is a rectangular steel plate made of Q235 carbon steel, with two sets symmetrically arranged at the upper ends of the fixed support block 31; the bolt 33 is a hexagonal head bolt made of high-strength carbon steel; and the nut 34 is a hexagonal lock nut, with a material matching that of the bolt 33.

[0024] In this embodiment, bolt 33 is rotatably connected to the end of connecting plate 32 away from fixed support block 31, bolt 33 is rotatably connected through to the lower end of another set of connecting cylinders 21, and nut 34 is threadedly connected to bolt 33 to fasten support adjustment unit 3 to the lower side of height telescopic adjustment unit 2.

[0025] Specifically, a support method for a soft rock high slope anchor bolt support system is characterized by the following steps: Step 1, Site adaptation preparation: Place the fixed support block 31 of the support adjustment unit 3 on the ground below the area to be supported on the soft rock high slope, so that the anti-slip texture on the lower surface of the fixed support block 31 is in contact with the ground to ensure the stability of the support foundation. Step 2, Height Adjustment Operation: The rotating block 24 of the height telescopic adjustment unit 2 is clamped by the tool and rotated, which drives the bidirectional threaded rod 23 to rotate synchronously. The meshing action of the bidirectional threaded rod 23 and the inner drive thread 22 of the connecting cylinder 21 makes the two sets of connecting cylinders 21 move closer or further apart along the axial direction. At the same time, the guide slide rod 26 slides along the guide tube 25 to adjust the height of the entire support system until the support plate 11 reaches the preset support height. Step 3, Adjusting the angle of the support surface: Rotate the bolt 33 of the support adjustment unit 3 to adjust the relative angle between the fixed support block 31 and the height telescopic adjustment unit 2, so that the support plate 11 remains horizontal or adapts to the tilt angle required for slope support. After the angle is determined, tighten the nuts 34 at both ends of the bolt 33 to secure and lock the support adjustment unit 3 and the height telescopic adjustment unit 2. Step 4, Support Surface Adjustment and Anchor Bolt Fixing: The support surface adjustment mechanism 1, height telescopic adjustment unit 2, and support adjustment unit 3 together constitute the anchor bolt body. Based on environmental conditions such as the looseness of the soil and rock on the soft rock high slope and the required support force, the rotating rod 16 of the support surface adjustment mechanism 1 is rotated, causing the first drive block 17 to rotate. The first drive block 17 presses against the driven ball 18, pushing the push rod 19 to compress the second return spring 110. The second drive block 111 moves with the push rod 19 and slides between the two sets of wedge blocks 14. The first return spring 15 causes the wedge blocks 14 to slide opposite each other along the limiting fixing groove 13 and the guide groove 113, releasing the limitation on the adjusting sliding plate 12. The sliding adjustment plate 12 is slid along the inner side of the support plate 11 to change the overlap area between the sliding adjustment plate 12 and the support plate 11, thereby increasing or decreasing the surface area of ​​the support surface to adapt to the support requirements of different environments. After the surface area is adjusted, the rotating rod 16 is rotated in the opposite direction. The second return spring 110 drives the push rod 19 and the second drive block 111 to return to their original positions. The second drive block 111 moves with the push rod 19 and squeezes the two sets of wedge blocks 14 through the inclined surface, so that the wedge blocks 14 slide to both sides along the limiting and fixing slide groove 13 and the guide slide groove 113. The wedge blocks 14 are inserted into the limiting and fixing slide groove 13 at the corresponding positions, locking the adjusting sliding plate 12 and completing the adaptation adjustment of the anchor support surface. Step 5, Support Maintenance: After adjustment, the main body of the anchor rod fits into the soft rock slope through the support surface. The adaptable surface area of ​​the support surface enhances the contact and stress effect with the soil and rock. The locking structure of the height telescopic adjustment unit 2 and the support adjustment unit 3 ensures the stability of the height and angle of the main body of the anchor rod. If the soft rock slope environment changes or the support effect needs to be adjusted, repeat the operation of step 4 to readjust the surface area of ​​the support surface to ensure that the anchor rod always adapts to the environmental requirements and maintains a stable support state.

[0026] Working principle or structural principle: First, place the fixed support block 31 of the support adjustment unit 3 on the ground of the area to be supported, using the anti-slip texture to ensure the stability of the foundation. By rotating the rotating block 24 of the height telescopic adjustment unit 2, the bidirectional threaded rod 23 is driven to rotate, causing the two sets of connecting cylinders 21 to extend and retract axially. With the guidance of the guide slide rod 26 and the guide tube 25, the support plate 11 is adjusted to the preset height. Rotate the bolt 33 of the support adjustment unit 3 to adjust the relative angle between the fixed support block 31 and the height telescopic adjustment unit 2. Tighten the nut 34 to complete the angle locking. The support surface adjustment mechanism 1, the height telescopic adjustment unit 2, and the support adjustment unit 3 together constitute the anchor bolt body. According to the slope environment, rotate the rotating rod 16 to drive the first drive block 17 to rotate, squeezing the driven ball 18 to push the push rod 19 to compress the second return spring 110. The second drive block 111 slides between the two sets of wedge blocks 14. The first return spring 15 drives the wedge blocks 14 to slide in opposite directions. The movement releases the limit on the adjusting sliding plate 12; the sliding adjusting sliding plate 12 changes the surface area of ​​the support surface to adapt to environmental requirements, and then the rotating rod 16 is rotated in the opposite direction. The second reset spring 110 drives the push rod 19 and the second drive block 111 to reset. The second drive block 111 slides to both sides through the inclined surface pressing the wedge block 14 and locks the adjusting sliding plate 12 into the limiting and fixing groove 13. Finally, the anchor body fits with the slope through the adapted support surface, and the height and angle locking structure maintains a stable support state. When adjustment is needed, the support surface adjustment steps can be repeated.
