An assembled steel corrugated plate retaining wall

Abstract

This invention belongs to the field of road construction technology and discloses a prefabricated corrugated steel retaining wall. It includes anchor rods inserted into the corrugated sheet and soil layer to fix the corrugated sheet in place. A push rod passes through the anchor rod, which has a storage groove for storing concrete. A discharge port is located on the outside of the anchor rod; movement of the push rod causes the concrete in the storage groove to be discharged from the discharge port. A support part is slidably hinged to the push rod, allowing the push rod to move and expand the support part. The discharge port is located on the side of the support part near the corrugated sheet, allowing the discharged concrete to abut against the support part. The support part includes a slider and an anchor plate. The slider slides within a groove and can rotate freely. One end of the anchor plate is hinged to the slider. A support rod is connected to the side of the push rod near the groove, and one end of the support rod slides with the end of the anchor plate near the groove. This invention solves the problem in existing technologies where soft soil causes the corrugated sheet to easily loosen after installation, resulting in poor adhesion to the soil layer and subsequent collapse.

Description

Technical Field

[0001] The invention relates to the field of road construction technology, specifically to a prefabricated corrugated steel retaining wall. Background Technology

[0002] In regions with severe winters and deep permafrost, seasonal freeze-thaw cycles are intense. Traditional concrete retaining walls, due to their rigid structure, are extremely sensitive to uneven frost heave in the foundation, easily leading to cracking, overturning, and other defects. Corrugated steel plate structures, with their flexible characteristics, can effectively release the stress generated by frost heave through minute deformations, adapting to changes in the foundation and greatly improving the safety and durability of the structure in permafrost regions.

[0003] Strong earthquake resistance: The flexibility of corrugated steel plate structures gives them good ductility and earthquake resistance, effectively absorbing and dissipating earthquake energy and reducing inertial forces under earthquake action. This is superior to brittle concrete structures and is more conducive to ensuring the safety of lifeline projects.

[0004] Low foundation requirements: Corrugated steel sheet retaining walls are lightweight structures, requiring significantly lower foundation bearing capacity than heavy concrete gravity retaining walls. In areas with poor geological conditions, such as parts of Xinjiang, this can significantly reduce the depth and cost of foundation treatment and simplify the construction process. However, due to the relatively loose soil, the corrugated sheets are prone to loosening and poor adhesion to the soil layer after installation, leading to collapse. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a prefabricated corrugated steel retaining wall to solve the problem that in existing technologies, the soil is relatively soft, which makes the corrugated plates prone to loosening and poor adhesion to the soil layer after installation, leading to the collapse of the corrugated plates.

[0006] A prefabricated corrugated steel retaining wall includes anchor rods, which pass through the corrugated plate and are inserted into the soil layer to fix the corrugated plate. A push rod is inserted into an anchor rod, and a storage tank for storing concrete is provided inside the anchor rod. A discharge port communicating with the storage tank is provided on the outside of the anchor rod located in the soil layer. The push rod moves to discharge the concrete in the storage tank from the discharge port. The support is slidably hinged to the push rod, which moves the push rod to open the support. The discharge port is located on the side of the support near the corrugated plate, so that the concrete is discharged and then abuts against the support.

[0007] Furthermore, the support includes a slider and an anchor plate. A groove is provided on one side of the anchor rod. The slider slides within the groove and can rotate freely. One end of the anchor plate is hinged to the slider. A support rod is connected to the side of the push rod near the groove. One end of the support rod slides with the end of the anchor plate near the groove.

[0008] Furthermore, one end of the slider is connected to an anti-rotation component, which includes a ratchet, a rotating shaft, a torsion spring, a stop bar, and a locking block. The ratchet is axially rotatably connected to the end of the slider. The end of the ratchet away from the slider is fixedly connected to an anchor plate. One end of the rotating shaft is fixedly connected to the outside of the slider, and the torsion spring covers the outside of the rotating shaft. One end of the locking block is fixedly connected to the outside of the torsion spring, and the other end of the locking block abuts against the ratchet, so that the ratchet can only rotate in one direction. One end of the stop bar is connected to the slider to block the locking block and prevent the locking block from disengaging from the ratchet tooth gap.

[0009] Furthermore, the push rod is connected to a push plate, which is slidably connected within the storage tank to extrude concrete.

[0010] Furthermore, the discharge port extends towards the anchor plate so that the discharged concrete abuts against the anchor plate.

[0011] Furthermore, both sides of the anchor rod are provided with push rods and support parts to ensure that the anchoring force of the anchor rod is uniform.

[0012] Furthermore, the end of the anchor rod near the corrugated plate is pointed.

[0013] Furthermore, a shielding head is connected to the outside of the anchor rod, and the shielding head is located on the side of the groove near the sharp end.

[0014] Furthermore, a fixing plate is connected to the outside of the anchor rod, and a stress-relieving plate is placed between the fixing plate and the corrugated plate. The fixing plate and the corrugated plate are fixed together by screws.

[0015] Furthermore, the anchor rod is equipped with a protective cover at the detachment connection away from the sharp end.

[0016] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: 1. By combining anchor rods and corrugated plates, the retaining wall can be quickly assembled and reliably fixed; the push rod and the support unit work together, and after the anchor rod is inserted into the soil, it can actively open the anchor plate and squeeze out concrete at the same time, so that the concrete solidifies and forms a reliable support with the support unit, enhancing the pull-out resistance and overall stability of the anchor rod; fixing, supporting and grouting reinforcement are integrated into one, making construction convenient and the structure stable.

[0017] 2. By adding anti-rotation components (ratchet, locking block, torsion spring, etc.), the anchor plate is prevented from accidentally rotating and closing under soil pressure, ensuring that the state of the support can be locked permanently after it is deployed; the reliability and durability of the anchoring are improved by the one-way locking mechanism, avoiding anchoring failure caused by soil creep or pressure changes; the symmetrical setting of support components on both sides further ensures the uniform distribution and overall balance of the anchoring force.

[0018] 3. By optimizing the shape of the anchor rod end (sharp shape) and adding a shielding head, the smoothness of penetration into the soil layer is improved, and the soil entry into the chute is effectively prevented from affecting the operation of the mechanism, thus creating conditions for the smooth deployment of the anchor plate. Through the combined design of the fixing plate and the unloading plate, especially the application of the bent unloading plate, the vibration and impact borne by the corrugated plate can be effectively absorbed and buffered, preventing the connecting bolt from loosening due to long-term vibration, thereby improving the long-term stability and safety of the entire connection node.

[0022] The embodiments of the invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative and should not be construed as limiting the scope of protection of the invention. Example 1:

[0023] like Figures 1-5 As shown in the figure, the prefabricated steel corrugated plate retaining wall provided in this embodiment includes: anchor rod 1, which is inserted into the corrugated plate 2 and the soil layer 13 to fix the corrugated plate 2; both the upper and lower ends of the corrugated plate 2 are wrapped and fixed with concrete protective layer 14 to prevent the corrugated plate 2 from collapsing.

[0024] A push rod 6 is inserted into the anchor rod 1, allowing it to slide within the anchor rod 1. The anchor rod 1 has a storage tank 3 for storing concrete, and a discharge port 4 is located on its outer side. The concrete in the storage tank 3 is discharged through the discharge port 4. Moving the push rod 6 causes the concrete in the storage tank 3 to be discharged from the discharge port 4. After the concrete solidifies, it provides support to the support portion 5, preventing the anchor rod 1 from sliding. The support part 5 is slidably hinged to the push rod 6, allowing the push rod 6 to move and expand the support part 5. At this time, the anchor rod 1 forms an anchoring force and comes into contact with the soil layer 13 and the concrete. The discharge port 4 is located on the side of the support part 5 near the corrugated plate 2, so that the concrete abuts against the support part 5. The push rod 6 is connected to a push plate 8, which is slidably connected in the storage tank 3 to squeeze out the concrete. The discharge port 4 extends towards the anchor plate 51 so that it abuts against the anchor plate 51 when the concrete is discharged.

[0025] The support part 5 includes a slider 53 and an anchor plate 51. A groove 52 is provided on one side of the anchor rod 1, and the slider 53 slides within the groove 52 and can rotate freely. One end of the anchor plate 51 is hinged to the slider 53, so that the slider 53 can drive the anchor plate 51 to rotate. A support rod 61 is connected to the side of the push rod 6 near the groove 52. One end of the support rod 61 slides with the end of the anchor plate 51 near the groove 52 to push the anchor plate 51 to rotate and open the anchor plate 51.

[0026] The working principle of Example 1 is explained in detail below: The corrugated plate 2 is placed vertically on the slope of soil layer 13. Concrete is poured on both the upper and lower sides of the corrugated plate 2, and reinforcing bars are driven in. After fixing both ends of the corrugated plate 2, the middle part of the corrugated plate 2 is fixed. Holes are made in the corrugated plate 2, and anchor rods 1 are inserted into them, now embedded in soil layer 13. A push rod 6 is driven into the anchor rod 1. The push rod 6 moves, causing the push plate 8 to move, squeezing concrete out of the discharge port 4. The concrete is now located within soil layer 13. The push rod 6 moves, causing the support rod 61 to move. The support rod 61 expands the anchor plate 51, and the concrete resists the anchor plate 51, increasing the anchoring force.

[0027] The beneficial effects of the above scheme are as follows: By combining the anchor rod 1 with the corrugated plate 2, the retaining wall can be quickly assembled and reliably fixed. The push rod 6, linked with the support part 5, can actively open the anchor plate 51 and simultaneously squeeze out concrete after the anchor rod 1 is inserted into the soil layer 13. This allows the concrete to solidify and form a reliable support with the support part 5, significantly enhancing the pull-out resistance and overall stability of the anchor rod 1. This design integrates fixing, support, and grouting reinforcement into one unit, making construction convenient and the structure stable. Example 2:

[0028] like Figures 1-7 As shown, one end of the slider 53 is connected to an anti-rotation component 7 to prevent the anchor plate 51 from rotating back into the slide groove 52. The anti-rotation component 7 includes: a ratchet 71, a rotating shaft 72, a torsion spring 73, a stop bar 75, and a locking block 74. The ratchet 71 is axially rotatably connected to the end of the slider 53. The end of the ratchet 71 away from the slider 53 is fixedly connected to the anchor plate 51. When the anchor plate 51 rotates and opens, it drives the ratchet 71 to rotate. One end of the rotating shaft 72 is fixedly connected to the outside of the slider 53. The torsion spring 73 covers the outside of the rotating shaft 72. One end of the locking block 74 is fixedly connected to the outside of the torsion spring 73, and the other end of the locking block 74 abuts against the ratchet 71, so that the ratchet 71 can only rotate in one direction. The locking block 74 is used to prevent the ratchet 71 from rotating in reverse. The torsion spring 73 keeps the locking block 74 in a state where it can lock the ratchet 71. One end of the stop bar 75 is connected to the slider 53 to block the locking block 74 and prevent the locking block 74 from disengaging from the gap between the teeth of the ratchet 71. Both sides of the anchor rod 1 are provided with push rods 6 and support parts 5 to make the anchoring force of the anchor rod 1 uniform.

[0029] The working principle of Embodiment 2 is explained in detail below: When the support rod 61 pushes the anchor plate 51 to rotate, the ratchet 71 rotates, while the slider 53 does not rotate and slides within the groove 52. The rotation of the ratchet 71 causes the locking block 74 to rotate. When the ratchet 71 stops rotating, the torsion spring 73 pulls the locking block 74 to rotate back, thereby locking the ratchet 71 and preventing it from rotating back. The ratchet 71 not rotating back prevents it from being squeezed by soil in the soil layer 13, which would cause the anchor plate 51 to close and lose its anchoring effect.

[0030] The beneficial effects of the above scheme are as follows: By adding anti-rotation components 7 (ratchet 71, locking block 74, torsion spring 73, etc.), the anchor plate 51 is effectively prevented from accidentally rotating and closing under the pressure of the soil layer 13, ensuring that the extended state of the support part 5 can be permanently locked. This unidirectional locking mechanism greatly improves the reliability and durability of the anchoring, avoiding anchoring failure caused by soil creep or pressure changes. The symmetrical arrangement of the support parts 5 on both sides further ensures the uniform distribution and overall balance of the anchoring force. Example 3:

[0031] like Figures 1-4As shown, the end of the anchor rod 1 near the corrugated plate 2 is sharp to facilitate penetration into the soil layer 13. A shielding head 9 is connected to the outside of the anchor rod 1. The shielding head 9 is located on the side of the chute 52 near the sharp end, blocking soil from falling into the chute 52 and simultaneously spreading the soil to facilitate the opening of the anchor plate 51. A fixing plate 10 is connected to the outside of the anchor rod 1. A stress-relief plate 12 is placed between the fixing plate 10 and the corrugated plate 2. The stress-relief plate 12 is bent to reduce vibration and prevent the screw 11 from loosening. The fixing plate 10 and the corrugated plate 2 are fixed together by the screw 11. A protective cover 15 is detachably connected to the anchor rod 1 away from the sharp end to prevent accidental contact with the push rod 6.

[0032] The working principle of Embodiment 3 is explained in detail below: When the anchor rod 1 is inserted into the soil layer 13, the blocking head 9 also pushes the soil layer 13 away, thereby reducing the amount of soil on the movement trajectory of the anchor plate 51 when it unfolds, making it easier for the anchor plate 51 to unfold. When the screw 11 is turned into the corrugated plate 2, the fixing plate 10 and the stress relief plate 12 are fixed. When the stress relief plate 12 is subjected to force and vibration on the corrugated plate 2, the stress relief plate 12 is compressed and will not transmit the vibration force to the head of the screw 11, causing the fixing plate 10 to loosen. This allows the screw 11 to firmly fix the fixing plate 10.

[0033] The beneficial effects of the above scheme are as follows: By optimizing the end shape of the anchor rod 1 (sharp shape) and adding a shielding head 9, the smoothness of penetration into the soil layer 13 is greatly improved, while effectively preventing soil from entering the chute 52 and affecting the operation of the mechanism, thus creating conditions for the smooth deployment of the anchor plate 51. The combined design of the fixing plate 10 and the unloading plate 12, especially the application of the bent unloading plate 12, can effectively absorb and buffer the vibration and impact borne by the corrugated plate 2, preventing the connecting screw 11 from loosening due to long-term vibration, thereby improving the long-term stability and safety of the entire connection node. The setting of the protective cover 15 also increases operational safety.
