Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology for high backfill curved road sections, specifically to a retaining wall mechanism for high backfill curved roads. Background Technology

[0002] As road construction extends into complex terrain, the backfill height of high-backfill curves continues to increase, and the load on retaining walls continues to rise, placing higher demands on the retaining walls' resistance to overturning and their ability to resist water and soil pressure.

[0003] However, the existing retaining walls on high-backfill curved road sections have particularly prominent problems with insufficient anti-overturning performance in actual use. They are prone to the risk of the wall rotating around its toe and collapsing, especially during the rainy season. Rainwater seeps into the backfill soil behind the wall, causing the backfill soil to become saturated with water, which significantly increases the self-weight of the backfill soil and directly increases the lateral pressure on the retaining wall. In addition, the saturated backfill soil will generate a sharp increase in pore water pressure. This pressure will significantly offset the effective stress between soil particles and significantly reduce the internal friction angle of the soil, resulting in a sharp decrease in the shear strength of the soil. This will generate a huge thrust on the retaining wall that is far beyond the design expectation. Under this thrust, the entire wall is very likely to overturn, which will not only affect the normal passage of the road, but may also cause safety accidents such as collapse, resulting in serious economic losses and safety hazards. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a retaining wall mechanism for high backfill curved road sections. It has the advantages of being able to adjust the retaining wall height synchronously with the backfill height and forming a double anchor to enhance the anti-overturning ability. This solves the problems of insufficient anti-overturning performance of existing retaining walls and the increased thrust on the wall due to saturated backfill during the rainy season, which can easily lead to overall overturning.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a retaining wall mechanism for high backfill curved road sections, comprising an L-shaped retaining wall. Two stepped bases are symmetrically fixedly installed on the top of one end of the L-shaped retaining wall. Several insertion holes are provided on the top of the stepped bases. A rectangular groove is provided on the top of the L-shaped retaining wall. A first sliding hole is provided on the side of the L-shaped retaining wall near the stepped bases, close to the top, and communicates with the rectangular groove. An extension plate is movably installed inside the rectangular groove. Several drainage holes are provided on the side of the L-shaped retaining wall near the bottom. An anchoring component for preventing tipping is fixedly installed on the top of the extension plate via a connecting assembly. An adjusting component is provided on the side of the L-shaped retaining wall near the stepped bases. The anchoring component consists of an installation cylinder and a first insertion rod.

[0006] As a preferred embodiment of this utility model, the connecting assembly includes a mounting rod, which is fixedly mounted on the top of the extension plate by a first bolt. Rectangular sleeves are rotatably mounted on both ends of the mounting rod, and a threaded hole is provided on one side of the rectangular sleeve. A second bolt is threaded into the inside of the threaded hole.

[0007] As a preferred embodiment of this utility model, the connecting assembly further includes two extension rods, which are movably installed inside the rectangular sleeve. A plurality of fixing holes are provided on one side of the extension rod, and the other end of the second bolt is movably fitted inside the fixing hole. An installation ring is fixedly installed on the other end of the extension rod.

[0008] As a preferred technical solution of this utility model, the anchoring assembly includes two mounting cylinders, which are fixedly installed inside the mounting ring. A second sliding hole is provided on the outer side of the mounting cylinder, and a connecting pipe is rotatably installed on the top of the mounting cylinder. Two second sliding holes are symmetrically provided on the outer side of the connecting pipe.

[0009] As a preferred technical solution of this utility model, the anchoring assembly further includes a first insert rod, which is movably installed inside the mounting cylinder. The bottom end of the first insert rod is tapered, and a striking plate is fixedly installed on the outer side of the first insert rod. The striking plate passes through the second sliding hole, and an installation groove is opened at the top of the first insert rod. A support ring is fixedly installed inside the installation groove and near the top of the first insert rod. The connecting pipe passes through the support ring.

[0010] As a preferred embodiment of this utility model, the anchoring assembly further includes a rotating disk, which is rotatably installed on the inner bottom surface of the mounting groove. A connecting rod is fixedly installed on the top of the rotating disk, and the connecting rod is movably sleeved inside the connecting tube. Slider blocks are symmetrically fixedly installed on the outer side of the connecting rod, and the sliders are movably sleeved inside the second sliding hole.

[0011] As a preferred technical solution of this utility model, the anchoring assembly further includes four arc-shaped guide holes. The four arc-shaped guide holes are equidistantly opened on the top of the rotating disk. A round rod is movably sleeved inside the arc-shaped guide holes. A second insert rod is fixedly installed at the bottom of the round rod. Four movable holes are equidistantly opened on the outer side of the first insert rod along the circumference. The positions of the movable holes correspond to the positions of the second insert rod. The other end of the second insert rod is movably sleeved inside the movable holes.

[0012] As a preferred embodiment of this utility model, the adjustment component includes two U-shaped connecting blocks, which are symmetrically fixedly installed on one side of the extension plate. The U-shaped connecting blocks pass through the first sliding hole, and a connecting rod is rotatably installed inside the U-shaped connecting block. A U-shaped fixing rod is rotatably installed at the other end of the two connecting rods, and the two ends of the U-shaped fixing rod are movably sleeved inside the insertion hole.

[0013] The beneficial effects of this utility model are as follows: This invention, by setting a rectangular groove and a movable extension plate at the top of an L-shaped retaining wall, and using an adjustment assembly consisting of connecting rods and U-shaped fixing rods, allows the extension plate to be gradually adjusted by inserting the U-shaped fixing rods into different positions on the stepped base according to the actual progress and height requirements of the backfilling construction. This enables the retaining wall height to be increased gradually, allowing the backfilling operation to proceed synchronously. This avoids the problem of lateral pressure concentration caused by the backfilling height far exceeding the initial height of the retaining wall, significantly reducing the risk of retaining wall tilting and collapse during construction, and improving construction safety.

[0014] This utility model allows for flexible adjustment of the anchoring position and depth through the cooperation of the connecting component and the anchoring component. Utilizing the telescopic adaptability of the rectangular sleeve and the extension rod, the position of the installation ring can be adjusted according to the filling range of the curved section. Then, the first insert rod at the conical bottom end is hammered into the soil, and rotating the connecting pipe can drive the rotating disk to make the second insert rod extend out of the movable hole and insert into the surrounding soil to form a lateral anchoring, further enhancing the overturning resistance of the retaining wall.

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0018] Figure 1 - Figure 10 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 10 The present invention will be further described below.

[0019] The retaining wall mechanism for a high backfill curved road section includes an L-shaped retaining wall 1. Two stepped bases 2 are symmetrically fixedly installed on the top of one end of the L-shaped retaining wall 1. Several insertion holes 3 are opened on the top of the stepped bases 2. A rectangular groove 4 is opened on the top of the L-shaped retaining wall 1. A first sliding hole 5 is opened on the side of the L-shaped retaining wall 1 near the stepped bases 2 and near the top, which is connected to the rectangular groove 4. An extension plate 6 is movably installed inside the rectangular groove 4. Several drainage holes are opened on the side of the L-shaped retaining wall 1 near the bottom. An anchoring component for preventing tipping is fixedly installed on the top of the extension plate 6 through a connecting component. An adjustment component is provided on the side of the L-shaped retaining wall 1 near the stepped bases 2. The anchoring component consists of an installation cylinder 13 and a first insertion rod 17.

[0020] In this implementation scheme, an L-shaped retaining wall 1 provides basic frame support for the entire retaining wall. A stepped base 2 is symmetrically fixed to the top of the L-shaped retaining wall 1 near one end. Several insertion holes 3 on the top provide fixing points for the U-shaped fixing rod 8 of the adjustment component. By cooperating with the U-shaped fixing rod 8 and the connecting rod 7, the extension height of the extension plate 6 can be adjusted, so that the height of the retaining wall increases synchronously with the backfilling operation, avoiding the backfilling height from far exceeding the initial height of the retaining wall and causing lateral pressure concentration, thus reducing the risk of the retaining wall tilting. A rectangular groove 4 is opened at the top of the L-shaped retaining wall 1 to provide space for the extension plate 6 to move up and down. A first sliding hole 5 is opened on the side of the L-shaped retaining wall 1 near the stepped base 2 and near the top, and is connected to the rectangular groove 4. It is used to pass through the U-shaped connecting block of the adjustment component, so that the U-shaped connecting block can move synchronously with the movement of the extension plate 6. The extension plate 6 is movably mounted on the rectangular groove 4. Inside the L-shaped groove 4, the extension height can be adjusted by adjusting the components to gradually increase the overall height of the retaining wall, allowing the retaining wall height to advance synchronously with the backfilling operation. The drainage hole is opened on the side of the L-shaped retaining wall 1 near the bottom, which can promptly drain the water accumulated in the high backfill area, preventing water from seeping into the backfill soil, which would increase the soil's self-weight and reduce its shear strength. The connecting components can stably fix the anchoring components to the extension plate 6, and the position of the anchoring components can also be adjusted. The anchoring components are fixed to the top of the extension plate 6 through the connecting components, and the whole can move synchronously with the height adjustment of the extension plate 6. The double anchoring effect of the anchoring components greatly enhances the retaining wall's anti-overturning ability and prevents the retaining wall from collapsing under high backfilling pressure. The adjusting components can gradually adjust the height of the retaining wall, allowing the retaining wall height to be synchronized with the backfilling operation, avoiding safety hazards caused by the mismatch between the backfilling progress and the retaining wall height.

[0021] Specifically, the connecting assembly includes a mounting rod 9, which is fixedly mounted on the top of the extension plate 6 by a first bolt. Rectangular sleeves 10 are rotatably mounted on both ends of the mounting rod 9. A threaded hole is provided on one side of the rectangular sleeve 10, and a second bolt is threaded into the inside of the threaded hole.

[0022] In this embodiment, the mounting rod 9 is fixedly installed on the top of the extension plate 6 by the first bolt, providing a stable rotation mounting fulcrum for the rectangular sleeve 10. The mounting structures at both ends allow the two rectangular sleeves 10 to rotate flexibly, while firmly connecting the connecting assembly to the extension plate 6, ensuring that the entire connecting assembly moves synchronously with the extension plate 6. The first bolt is used to fix the mounting rod 9 on the top of the extension plate 6, and the mounting rod 9 and the extension plate 6 are detachably fixed by a threaded connection. The two rectangular sleeves 10 are rotatably installed at both ends of the mounting rod 9. Their rotation characteristics can adjust their angle with the mounting rod 9 to adapt to different requirements of the anchoring assembly position in the curved filling range. A threaded hole is opened on one side of the rectangular sleeve 10 for threaded connection with the second bolt. The second bolt is threaded into the threaded hole of the rectangular sleeve 10, and the other end can be movably fitted into the fixing hole of the extension rod 11. By tightening the second bolt, the relative position of the extension rod 11 and the rectangular sleeve 10 can be fixed, and by loosening it, the extension length of the extension rod 11 can be adjusted.

[0023] Specifically, the connecting assembly also includes two extension rods 11, which are movably installed inside the rectangular sleeve 10. Several fixing holes are provided on one side of the extension rod 11, and the other end of the second bolt is movably fitted inside the fixing hole. An installation ring 12 is fixedly installed on the other end of the extension rod 11.

[0024] In this embodiment, the extension rod 11 is movably installed inside the rectangular sleeve 10, allowing it to extend and retract flexibly along the length of the rectangular sleeve 10 to adjust its extension length. Several fixing holes on one side can cooperate with the second bolt to lock the position. The mounting ring 12 fixedly installed at the other end is used to fix the mounting ring 12. With the vertical rotation of the rectangular sleeve 10, the angle can be adjusted with the rectangular sleeve 10 to adapt to the angle requirements of different backfill areas in the high backfill section, ensuring that the anchoring component can be accurately aligned with the soil position to be anchored, facilitating subsequent anchoring operations and enhancing the anti-overturning effect of the retaining wall.

[0025] Specifically, the anchoring assembly includes two mounting cylinders 13, which are fixedly installed inside the mounting ring 12. A second sliding hole 14 is provided on the outer side of the mounting cylinder 13. A connecting pipe 15 is rotatably installed on the top of the mounting cylinder 13. Two third sliding holes 16 are symmetrically provided on the outer side of the connecting pipe 15.

[0026] In this embodiment, by fixing the mounting cylinder 13 inside the mounting ring 12, a movable installation space is provided for the first insertion rod 17, ensuring that the first insertion rod 17 can move stably up and down inside it. The second sliding hole 14 opened on the outside allows the striking plate 18 of the first insertion rod 17 to pass through and move, which facilitates the striking plate 18 to drive the first insertion rod 17 to be inserted into the soil. The connecting pipe 15 rotatably installed at the top provides a rotational base for adjusting the position of the second insertion rod 25. The connecting pipe 15 is rotatably installed at the top of the mounting cylinder 13, and two third sliding holes 16 are symmetrically opened on the outside. The connecting rod 21 is movably sleeved inside. By rotating itself, it can drive the slider 22 in the third sliding hole 16 on the outside to move, thereby driving the connecting rod 21 and the rotating disk 20 to rotate, providing power for the second insertion rod 25 to extend out of the movable hole 19.

[0027] Specifically, the anchoring assembly also includes a first insert rod 17, which is movably installed inside the mounting cylinder 13. The bottom end of the first insert rod 17 is tapered, and a striking plate 18 is fixedly installed on the outside of the first insert rod 17. The striking plate 18 passes through the second sliding hole 14, and a mounting groove is opened at the top of the first insert rod 17. A support ring is fixedly installed inside the mounting groove and near the top of the first insert rod 17. The connecting pipe 15 passes through the support ring.

[0028] In this embodiment, the first insertion rod 17 is movably installed inside the installation cylinder 13, with a tapered bottom end, which facilitates rapid insertion into the soil under external impact, forming initial vertical anchoring and enhancing the retaining wall's anti-overturning foundation. The installation groove at the top provides installation space for components such as the rotating disk 20 and connecting rod 21. The support ring fixed near the top of the groove allows the connecting pipe 15 to pass through, which not only supports and guides the connecting pipe 15 but also ensures the coordinated cooperation between itself, the connecting pipe 15, and the installation cylinder 13. At the same time, the striking plate 18 fixed on the outside is the point of application of external force, which can drive itself to move stably downward inside the installation cylinder 13.

[0029] Specifically, the anchoring assembly also includes a rotating disk 20, which is rotatably installed on the inner bottom surface of the mounting groove. A connecting rod 21 is fixedly installed on the top of the rotating disk 20. The connecting rod 21 is movably sleeved inside the connecting tube 15. A slider 22 is symmetrically fixedly installed on the outer side of the connecting rod 21. The slider 22 is movably sleeved inside the third sliding hole 16.

[0030] In this embodiment, by fixing the connecting rod 21 to the top of the rotating disk 20 and movably fitting it inside the connecting tube 15, with the slider 22 symmetrically fixed on the outside, it can rotate stably under the guidance of the connecting tube 15, directly transmitting the rotational force transmitted by the slider 22 to the rotating disk 20, thus achieving the connection of power from the slider 22 to the rotating disk 20. Its structure of movably fitting inside the connecting tube 15 ensures its own stability during rotation and allows it to be inserted into the soil synchronously with the first insert rod 17, always maintaining the cooperative relationship with the connecting tube 15 and the rotating disk 20, without affecting the power transmission path. The slider 22 is symmetrically fixed on the outside of the connecting rod 21 and movably fitting inside the third sliding hole 16 of the connecting tube 15, receiving the rotational force transmitted by the connecting tube 15 through the third sliding hole 16 and transmitting it to the connecting rod 21. During the insertion of the first insert rod 17 into the soil, it moves down synchronously with the connecting rod 21 and always maintains a stable position within the third sliding hole 16. After the first insert rod 17 is in place, rotating the connecting tube 15 can transmit the rotational force to the connecting rod 21.

[0031] Specifically, the anchoring assembly also includes four arc-shaped guide holes 23. The four arc-shaped guide holes 23 are equidistantly opened on the top of the rotating disk 20. A round rod 24 is movably fitted inside the arc-shaped guide holes 23. A second insert rod 25 is fixedly installed at the bottom of the round rod 24. Four movable holes 19 are equidistantly opened on the outer side of the first insert rod 17 along the circumference. The position of the movable holes 19 corresponds to the position of the second insert rod 25. The other end of the second insert rod 25 is movably fitted inside the movable holes 19.

[0032] In this embodiment, four arc-shaped guide holes 23 are equidistantly spaced on the top of the rotating disk 20, and a round rod 24 is movably fitted inside them. When the rotating disk 20 rotates, its arc-shaped trajectory pushes the round rod 24 to move along the guide direction of the holes, thereby driving the second insertion rod 25 to move synchronously. This provides a precise movement path for the second insertion rod 25 to extend out of the movable hole 19, ensuring that the four second insertion rods 25 can extend outward from the first insertion rod 17 simultaneously and evenly, forming a stable lateral anchor. The movable hole 19 is located outside the first insertion rod 17 and at the same position as the second insertion rod 25. Correspondingly, a second insert rod 25 is movably fitted, providing a lateral extension channel for the second insert rod 25 while restricting its direction of movement. This ensures that the second insert rod 25 can only be inserted into the soil laterally, preventing the anchoring effect from being affected by the tilt of the second insert rod 25. Four limiting grooves are equidistantly opened along the circumference of the inner bottom surface of the mounting groove. A limiting block is fixedly installed at the bottom of the second insert rod 25, and the limiting block is movably fitted inside the limiting groove. The setting of the limiting groove and the limiting block can provide guidance for the movement of the second insert rod 25 and prevent the second insert rod 25 from deviating during movement.

[0033] Specifically, the adjustment component includes two U-shaped connecting blocks, which are symmetrically fixedly installed on one side of the extension plate 6. The U-shaped connecting blocks pass through the first sliding hole 5. A connecting rod 7 is rotatably installed inside the U-shaped connecting block. A U-shaped fixing rod 8 is rotatably installed at the other end of the two connecting rods 7. The two ends of the U-shaped fixing rod 8 are movably sleeved inside the insertion hole 3.

[0034] In this embodiment, by symmetrically fixing the U-shaped connecting block on one side of the extension plate 6 and passing through the first sliding hole 5 of the L-shaped retaining wall 1, it can move synchronously within the first sliding hole 5 as the extension plate 6 moves up and down. At the same time, it provides a fulcrum for the rotation of the connecting rod 7, ensuring that the connecting rod 7 can flexibly adjust its angle. The extension plate 6 can adjust its extension height within the rectangular groove 4 through the cooperation of the U-shaped connecting block, the connecting rod 7 and the U-shaped fixing rod 8. One end of the connecting rod 7 is rotatably installed inside the U-shaped connecting block, and the other end is rotatably installed with the U-shaped fixing rod 8. It can change its angle by rotating itself, and the position change of the U-shaped fixing rod 8 is converted into a height change of the extension plate 6. When the U-shaped fixing rod 8 is inserted into the insertion hole 3 at different positions of the stepped base 2, the connecting rod 7 will drive the U-shaped connecting block and the extension plate 6 to move up and down, thereby adjusting the extension height of the extension plate 6. The two ends of the U-shaped fixing rod 8 are movably sleeved in the insertion hole 3 of the stepped base 2, and the middle part is rotatably connected to the connecting rod 7. By selecting different positions of the insertion hole 3 to fix its two ends, the angle of the connecting rod 7 can be fixed, thereby locking the height of the extension plate 6 and realizing the phased fixation of the retaining wall height.

[0035] In summary: When using this utility model, first fix the L-shaped retaining wall 1 in the designated position. Then, according to the initial backfill height, manually adjust the position of the extension plate 6 within the rectangular groove 4 at the top of the L-shaped retaining wall 1. During adjustment, manually push the U-shaped connecting block to move the extension plate 6 within the rectangular groove 4, causing the symmetrically fixed U-shaped connecting blocks on one side to move along the first sliding hole 5. Simultaneously, this causes the connecting rod 7, which is rotatably connected to the U-shaped connecting blocks, to change its angle. After the extension plate 6 is adjusted to a suitable height, manually insert both ends of the U-shaped fixing rod 8 into the corresponding positions at the top of the stepped base 2. The extension plate 6 is fixed in the insertion hole 3. Then, according to the filling range of the curved section, the connecting components are manually adjusted. First, use a wrench to loosen the second bolt in the threaded hole on one side of the rectangular sleeve 10. Then, manually pull the extension rod 11 to extend and retract within the rectangular sleeve 10. After adjusting to the appropriate length, manually tighten the second bolt with a wrench so that the other end of the second bolt is inserted into the corresponding fixing hole on one side of the extension rod 11 to fix the position of the extension rod 11. At the same time, the rectangular sleeve 10 can be manually rotated to adjust the angle of the mounting ring 12 and the anchoring components so that the anchoring components are aligned with the anchoring components. In the soil area, after completing the preliminary preparations and entering the anchoring stage, manually tap the tapping plate 18 on the outside of the first insertion rod 17 with a tool. The tapping plate 18 slides downward along the second sliding hole 14 on the outside of the mounting cylinder 13, causing the first insertion rod 17 to move downward inside the mounting cylinder 13, so that the conical bottom end of the first insertion rod 17 is inserted deep into the soil. After the first insertion rod 17 is inserted into place, manually rotate the connecting pipe 15 at the top of the mounting cylinder 13 with a tool. The connecting pipe 15 drives the slider 22 to rotate through the third sliding hole 16 on the outside. The slider 22 is fixed to the outside of the connecting rod 21. The connecting rod 21 rotates within the connecting pipe 15. The bottom of the connecting rod 21 is fixed to the rotating disk 20, thus causing the rotating disk 20 to rotate within the mounting groove at the top of the first insert rod 17. When the rotating disk 20 rotates, the arc-shaped guide holes 23, which are equidistantly opened on its top circumference, push the round rod 24 sleeved inside to move. The second insert rod 25, which is fixed at the bottom of the round rod 24, moves with the round rod 24 and extends out from the corresponding movable hole 19 on the outside of the first insert rod 17, inserting into the surrounding soil to form a lateral anchorage. This works in conjunction with the vertical anchorage of the first insert rod 17 to complete the anchorage and fixation of the retaining wall.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
