Description

Technical Field

[0001] This invention belongs to the field of slope reinforcement technology, specifically relating to a combined reinforcement structure for retaining walls on high slopes. Background Technology

[0002] During current road construction, some construction and operating roads have significant elevation differences on their exposed sides. Furthermore, due to limitations imposed by terrain and geological conditions, the foundation space at the slope base is limited or the foundation strength is insufficient. Under the influence of long-term soil pressure, winter freeze-thaw cycles, and rainwater infiltration and erosion, retaining walls are prone to outward tilting, subsidence, and localized bulging, compromising structural safety. To address these issues, existing technologies often employ retaining wall reinforcement. However, due to the long-term effects of thermal expansion and contraction, reinforced structures frequently loosen, failing to provide adequate support for high slopes when suddenly subjected to heavy vehicle loads. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a combined reinforcement structure for high slope retaining walls, which can improve the supporting force of the reinforcement structure and reduce the internal force borne by the reinforcement structure when dealing with large vehicle loads, with good overall stress condition and can increase slope stability.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention discloses a combined reinforcement structure for a high slope retaining wall, comprising a high slope and a retaining wall disposed on one side of the high slope. The retaining wall slopes downward and extends towards the side of the high slope. The outer side of the retaining wall is supported by buttress columns. A receiving cavity is formed inside the high slope, and an installation plate is fixed within the receiving cavity. A first support seat, a second support seat, and a third support seat are simultaneously fixed on the installation plate. A plurality of blind holes are formed on the upper surface of the high slope. The blind holes are arranged in several groups at uniform intervals along the longitudinal direction, and each group of blind holes is arranged at uniform intervals along the transverse direction. A force-bearing block is slidably disposed vertically within each blind hole, with its upper end extending out of the blind hole. A support rod is connected to the lower end of the force-bearing block. The support rod is slidably engaged with the first support seat. A fixed block is connected to the middle of the support rod. Active rods are connected to the fixed blocks in the same group of blind holes. The end of the active rod facing the retaining wall is hinged to one end of the first connecting rod. The other end of the first connecting rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is eccentrically connected to a worm gear. The worm gear is rotatably connected to the second support seat. The worm gear engages with a worm. The worm is rotatably connected to the third support seat. A pulley is coaxially connected to the worm. A tension cable is wound around the pulley. The outer end of the tension cable extends horizontally and is connected to the buttress column.

[0006] Furthermore, a spring is sleeved on the outer side of the support rod, and the two ends of the spring are respectively connected to the force-bearing block and the bottom of the blind hole.

[0007] Furthermore, a steel sleeve is provided at the bottom of the blind hole, and the support rod is slidably engaged with the steel sleeve.

[0008] Furthermore, a damping groove is provided at the bottom of the receiving cavity, the damping groove is filled with damping fluid, and multiple damping plates are arranged at intervals at the lower end of the support rod, with through holes provided on the damping plates.

[0009] Furthermore, multiple drainage pipes are fixed inside the retaining wall, with one end of each drainage pipe extending into the inner side of the high slope and the other end extending downwards and out of the retaining wall.

[0010] Furthermore, a vertical beam is provided between the retaining wall and the buttress column. The vertical beam is made of flexible concrete and is pressed between the buttress column and the retaining wall.

[0011] Furthermore, the buttress column is supported by a diagonal bracing beam. A vertical steel rail is fixed to the outside of the buttress column. The upper end of the diagonal bracing beam cooperates with the vertical steel rail. The diagonal bracing beam is triangularly supported on the outside of the buttress column. The middle part of the diagonal bracing beam is connected to a horizontal beam through a prestressed cable. The horizontal beam and the vertical beam are integrated into an L-shape. A jack for the diagonal bracing beam is installed on the horizontal beam.

[0012] Furthermore, the outer end of the horizontal beam is provided with a compression pile, which extends vertically. The lower end of the inclined bracing beam is hinged to the compression pile, and the upper end of the inclined bracing beam is hinged to a pressure plate. The inclined bracing beam is connected to the vertical rail through the pressure plate.

[0013] Furthermore, several anchor piles are also provided on the lower side of the horizontal beam.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention discloses a combined reinforcement structure for retaining walls on high slopes. By setting load-bearing blocks on the high slopes, when these blocks encounter large loads, the force can be transferred to tension cables. These cables tighten the buttress columns to the outer wall of the retaining wall, thus supporting the lateral pressure on the retaining wall. By employing this structure, the load can be partially offset. When dealing with large vehicle loads, the supporting force of the reinforcement structure can be increased, and the internal forces borne by the reinforcement structure can be reduced.

[0016] In the reinforcement structure disclosed in this invention, multiple sets of load-bearing blocks correspond to buttress columns on the same cross-section. By setting multiple sets of buttress columns longitudinally, the pressure on the entire upper surface of the high slope can be supported, thus effectively reinforcing the retaining wall. The overall stress distribution is good, which can increase the stability of the slope.

[0017] In the reinforcement structure disclosed in this invention, the pulleys are arranged in two sets, one above the other, which can tighten the buttress columns at different heights and can share the tension of a single tension cable, ensuring the stability of the structure during operation.

[0018] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0026] like Figures 1-5 As shown, the present invention discloses a combined reinforcement structure for a high slope retaining wall, comprising a high slope 1 and a retaining wall 2 disposed on one side of the high slope 1. With the extension direction of the high slope 1 as the longitudinal direction, the upper surface of the high slope 1 is parallel to the horizontal plane, and the side is limited by the retaining wall 2. The slope of the retaining wall 2 is inclined downwards and extends towards the side where the high slope 1 is located, thereby improving the stability of the retaining wall 2 support.

[0027] The retaining wall 2 is supported on its outer side by buttress columns 3, which are arranged in several groups at even intervals along the longitudinal direction. A receiving cavity 4 is provided inside the high slope 1, and an installation plate 5 is fixed inside the receiving cavity 4, vertically installed on the inner wall of the receiving cavity 4. Anchor nails are provided on the back side of the installation plate 5 to secure it firmly to the inner wall of the receiving cavity 4. The depth of the receiving cavity 4 can be selected as needed to ensure the structural strength of the high slope 1.

[0028] Specifically, a first support base 6, a second support base 7, and a third support base 8 are simultaneously fixed on the mounting plate 5; the openings of the first support base 6 and the third support base 8 are vertical, while the opening of the second support base 7 is horizontal. Several blind holes 9 are formed on the upper surface of the high slope 1. These blind holes 9 are arranged in several groups at even intervals along the longitudinal direction, with each group consisting of four blind holes 9, and are evenly spaced horizontally. A load-bearing block 10 is slidably installed vertically inside each blind hole 9, with its upper end extending from the blind hole 9 to receive the load applied to the upper surface of the high slope 1.

[0029] In this embodiment of the invention, a support rod 11 is connected to the lower end of the force-bearing block 10. The support rod 11 has a rectangular cross-section and is slidably engaged with the first support seat 6. The support rod 11 can rotate vertically. A fixing block 12 is connected to the middle of the support rod 11. Active rods 13 are connected to the fixing blocks 12 in the same group of blind holes 9. The axis of the active rod 13 is horizontal. One end of the active rod 13 facing the retaining wall 2 is hinged to one end of the first connecting rod 14. The other end of the first connecting rod 14 is hinged to one end of the second connecting rod 15. The other end of the second connecting rod 15 is eccentrically connected to the worm gear 16. The worm gear 16 is rotatably connected to the second support seat 7. The worm gear 16 is engaged with the worm 17. The worm 17 is rotatably connected to the third support seat 8. A pulley 18 is coaxially connected to the worm 17. A tension cable 19 is wound on the pulley 18. The outer end of the tension cable 19 extends horizontally and is connected to the buttress column 3. The buttress column 3 is supported on the outer wall of the retaining wall 2.

[0030] By employing the above-described structure, the device of the present invention can effectively convert vertical loads into tensile forces that tighten the buttress columns 3, thereby providing a certain degree of offset to the loads applied to the upper surface of the high slope 1. When dealing with large vehicle loads, it can improve the supporting force of the reinforced structure.

[0031] Specifically, in operation, a large load is applied to the load-bearing block 10, which drives the support rod 11 to move vertically. The fixed block 12 on the support rod 11 drives the active rod 13 to move. The active rod 13 drives the eccentric rod to rotate through the first connecting rod 14 and the second connecting rod 15. The eccentric rod drives the worm wheel 16 to rotate, which in turn drives the worm 17 to rotate. When the worm 17 rotates, it tightens the tension cable 19 wound on the pulley 18. The tension cable 19 pulls the buttress column 3 to the outer wall of the retaining wall 2 to support the lateral pressure on the retaining wall 2. By adopting the above structure, the load can be offset to a certain extent. When dealing with large vehicle loads, the supporting force of the reinforced structure can be increased, and the internal force borne by the reinforced structure can be reduced.

[0032] In this embodiment, a spring 20 is sleeved on the outer side of the support rod 11, and the two ends of the spring 20 are connected to the bottom of the force-bearing block 10 and the blind hole 9, respectively. By setting the spring 20, an elastic support force can be provided to the force-bearing block 10. When the load is lost, the force-bearing block 10 can be restored to its original position, thereby being able to cope with the next load. In the device of the present invention, the gaps between the force-bearing blocks 10 are filled with support plates to ensure the smoothness of the road surface of the high slope 1. The support plates have low hardness and are easily crushed. When encountering a relatively large load, the support plates can be crushed, which can facilitate the application of force to the force-bearing blocks 10. Subsequently, the support plates are replaced, and the support plates can normally support small loads to ensure the stability of vehicle driving.

[0033] In this embodiment, a steel sleeve 21 is provided at the bottom of the blind hole 9, and the support rod 11 slides in conjunction with the steel sleeve 21. By providing the steel sleeve 21, it is convenient for the support rod 11 to cooperate with the interior of the high slope 1, reducing the possibility of jamming. A damping groove 22 is provided at the bottom of the receiving cavity 4, and the damping groove 22 is filled with damping fluid. Multiple damping plates 23 are arranged at intervals at the lower end of the support rod 11, and through holes 24 are provided on the damping plates 23. When the stress block 10 encounters a large concentrated stress, the support rod 11 has a large vertical displacement, which allows the damping plates 23 to penetrate deeper into the damping groove 22. The damping fluid continuously passes through the through holes 24, which can play a damping role. Thus, under large loads, the load can be damped and buffered to further protect the high slope 1 and reduce the stress on the retaining wall 2.

[0034] In this embodiment, multiple drainage pipes 25 are fixed inside the retaining wall 2. One end of each drainage pipe 25 extends into the inner side of the high slope 1, while the other end extends downwards and protrudes from the retaining wall 2. By installing the drainage pipes 25, water accumulated inside the slope can be drained, preventing excessive soil moisture from causing slope instability. The drainage pipes 25 can promptly remove water accumulated inside the slope, reducing infiltration pressure on the soil and thus maintaining slope stability. Simultaneously, the drainage pipes 25 also prevent soil particles from being eroded away, protecting the integrity and stability of the slope structure.

[0035] In this embodiment, a vertical beam 26 is provided between the retaining wall 2 and the buttress column 3. The vertical beam 26 is made of flexible concrete, which can be compressed to a certain extent, reducing the hard damage to the outer reinforcement structure caused by the thermal expansion and contraction of the high slope 1, thus ensuring the supporting performance of the reinforcement structure. The vertical beam 26 is pressed tightly between the buttress column 3 and the retaining wall 2. Under large loads, it can also provide good protection for the high slope 1.

[0036] In this embodiment, the buttress column 3 is supported by a diagonal bracing beam 27. A vertical steel rail 28 is fixed to the outer side of the buttress column 3. The upper end of the diagonal bracing beam 27 cooperates with the vertical steel rail 28, and the diagonal bracing beam 27 is triangularly supported on the outer side of the buttress column 3. The middle part of the diagonal bracing beam 27 is connected to the horizontal beam 30 through a prestressed cable 29. The prestressed cable 29 provides downward prestress to the diagonal bracing beam 27. When the tension of the buttress column 3 under the force of the cable 19 is too large, the buttress column 3 compresses the vertical beam 26 and deflects inward. At this time, the upper end of the diagonal bracing beam 27 moves downward to ensure a better support state at all times. At this time, the soil pressure of the high slope 1 can be supported by the supporting force of the diagonal bracing beam 27, making the structure more stable and protecting the integrity and stability of the high slope 1 structure at all times.

[0037] In this invention, the horizontal beam 30 and the vertical beam 26 are integrated into an L-shape. A jack 31 for the diagonal bracing beam 27 is installed on the horizontal beam 30. After the large load is applied, if the diagonal bracing beam 27 is displaced, the jack 31 can be used to drive it back to its original position to cope with the next occurrence of a large load.

[0038] In this embodiment, a compression pile 32 is also provided at the outer end of the horizontal beam 30. The compression pile 32 extends vertically, and the lower end of the inclined bracing beam 27 is hinged to the compression pile 32. The upper end of the inclined bracing beam 27 is hinged to a pressure plate 33, and the inclined bracing beam 27 cooperates with the vertical rail 28 through the pressure plate 33. By setting the compression pile 32, the supporting force at the bottom of the inclined bracing beam 27 can be guaranteed, preventing damage to the stress area at the bottom of the inclined bracing beam 27 and increasing the supporting performance of the inclined bracing beam 27. This avoids damage to the triangular support structure itself and allows the force to be better transferred to the pile.

[0039] In this embodiment, several anchor piles 34 are also provided on the lower side of the horizontal beam 30 to increase the support stability of the horizontal beam 30.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
