Description

Technical Field

[0001] The embodiments of this utility model relate to the field of reinforced soil retaining wall technology, specifically to a block-type panel-wrapped reinforced soil retaining wall. Background Technology

[0002] In the fields of road, water conservancy, and municipal engineering construction, reinforced soil retaining walls are widely used in slope protection, embankment filling, and other scenarios due to their lightweight structure, high construction efficiency, and strong adaptability to deformation. Among them, the panel, as an important component of reinforced soil retaining walls, plays a crucial role in transmitting lateral pressure from the soil, protecting the reinforcement material, and maintaining the integrity of the retaining wall's appearance.

[0003] Currently, reinforced soil retaining wall panels commonly used in engineering projects mostly adopt a prefabricated structure, formed by splicing together several precast concrete blocks. This type of prefabricated panel has advantages such as simple manufacturing, convenient transportation, and flexible construction, and can adapt to the needs of different project scales and retaining wall shapes. However, the connection of multiple precast blocks in the longitudinal direction (i.e., the height direction of the retaining wall) of existing prefabricated panels often relies solely on the superposition of the blocks' own weight or simple concave-convex fit, lacking an effective locking mechanism.

[0004] The aforementioned longitudinal connection method results in insufficient stability of the panel structure. Under long-term loads such as soil lateral pressure, external vibration, or changes in ambient temperature, the blocks are prone to relative displacement, loosening, or even separation. This not only causes cosmetic damage such as cracks and bulges on the retaining wall panel surface, affecting the aesthetics of the project, but also weakens the panel's ability to restrain the soil, thereby reducing the overall structural strength and deformation resistance of the reinforced soil retaining wall. In severe cases, it may lead to safety hazards such as instability and collapse of the retaining wall, while significantly increasing the later maintenance costs, making it difficult to meet the high standards of structural safety and durability required by modern engineering. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a reinforced soil retaining wall with a block-type panel, which solves the technical problem in the prior art where the assembled panel is composed of multiple prefabricated blocks, but the longitudinal connection lacks locking, resulting in an unstable connection.

[0006] According to one aspect, at least one embodiment of the present invention provides a block-type panel-enclosed reinforced soil retaining wall, comprising:

[0007] A precast block, wherein the top surface of the precast block has a first slot and a first through hole for accommodating longitudinal reinforcing bars, and the bottom surface of the precast block has a first protrusion; the inner wall of the first slot has a first sliding groove communicating with the first through hole, and the first protrusion has a snap-fit ​​groove; a first anti-detachment block is slidably connected in the first sliding groove, and one end of the first anti-detachment block is located in the first through hole.

[0008] A number of the prefabricated blocks are arranged in a horizontal and vertical array to form a spliced ​​panel. The first protrusion of two longitudinally adjacent prefabricated blocks is embedded in the first slot, and the first sliding groove is connected to the snap-fit ​​groove.

[0009] The first anti-detachment block is arranged to abut against the end of the longitudinal steel bar when the longitudinal steel bar is inserted into the first through hole from top to bottom, so as to drive the first anti-detachment block to slide in the first groove, so that the other end of the first anti-detachment block slides into the snap-fit ​​groove to limit the longitudinal relative displacement of the longitudinally adjacent precast blocks.

[0010] For example, in the block-type panel-wrapped reinforced soil retaining wall provided in at least one embodiment of the present invention, the first anti-detachment block has an abutment surface that extends downward in the direction of the axis of the first through hole at one end. When the longitudinal steel bar is inserted, it contacts the abutment surface to drive the first anti-detachment block to slide in the first groove.

[0011] For example, in the block-type panel-wrapped reinforced soil retaining wall provided in at least one embodiment of the present invention, the end of the first anti-detachment block away from the abutment surface is provided with a reset surface. When the first protrusion is embedded in the first slot, it abuts against the reset surface to push the abutment surface of the first anti-detachment block to slide into the first through hole.

[0012] For example, in at least one embodiment of the present invention, a limiting rod is provided in the first sliding groove, and a limiting sliding groove is provided on the first anti-detachment block. The limiting rod is slidably engaged in the limiting sliding groove to limit the sliding stroke of the first anti-detachment block.

[0013] For example, in the block-type panel-wrapped reinforced soil retaining wall provided in at least one embodiment of the present invention, the longitudinally adjacent precast blocks are arranged in a staggered manner, the top surfaces of the precast blocks are provided with side slots at both ends, and the bottom surfaces are provided with side protrusions at both ends; the side slots of two laterally adjacent precast blocks are connected to form a second slot, and the side protrusions of two laterally adjacent precast blocks abut against each other to form a second protrusion, and the second slot is used to accommodate the second protrusion of the upper precast block.

[0014] For example, in the block-type panel-wrapped reinforced soil retaining wall provided in at least one embodiment of the present invention, two first through holes are provided and symmetrically distributed along the transverse direction of the precast blocks, and a second sliding groove communicating with the first through hole is opened on the side wall of the side slot, and a second anti-detachment block is slidably connected in the second sliding groove.

[0015] For example, the block-type panel-wrapped reinforced soil retaining wall provided in at least one embodiment of this utility model further includes:

[0016] A base grid is laid on the foundation, with one end of it attached to the spliced ​​panel and extending upward, and the other end anchored in the foundation.

[0017] A reinforcing assembly, wherein a plurality of the reinforcing assemblies are arranged longitudinally on the base grid;

[0018] The reinforcing component includes:

[0019] A load-bearing grid is laid on the base grid, with one end of the grid away from the spliced ​​panel anchored in the foundation.

[0020] A package is disposed at one end of the stress-bearing grid near the spliced ​​panel, and the end of the stress-bearing grid is folded back to cover the package;

[0021] The fill layer is constructed above the load-bearing grid and is located between the enclosure and the foundation.

[0022] For example, in at least one embodiment of the present invention, a precast block with a panel-wrapped reinforced soil retaining wall is provided with an installation component on the side of the precast block near the foundation grid. The installation component is used to fix the transverse reinforcement. A gap is formed between the transverse reinforcement and the precast block. One end of the foundation grid passes through the gap to limit the displacement of the foundation grid relative to the spliced ​​panel.

[0023] For example, in at least one embodiment of the present invention, the mounting component is detachably connected to the precast block in the block-type panel-wrapped reinforced soil retaining wall.

[0024] For example, in the block-type panel-wrapped reinforced soil retaining wall provided in at least one embodiment of the present invention, a receiving space is formed between the reinforcing component and the spliced ​​panel, and the receiving space is filled with a filter layer.

[0025] The beneficial effects of the embodiments of this utility model are as follows:

[0026] In this invention, multiple mating relationships are formed between longitudinally adjacent precast blocks, effectively solving the problem of unstable connection caused by the lack of locking in the longitudinal connection of existing assembled panels. Specifically, the first protrusion on the bottom surface of the precast block is embedded in the first slot on the top surface, realizing the initial positioning and fitting between longitudinally adjacent precast blocks, providing a foundation for the subsequent locking structure; the communication structure between the first sliding groove and the first through hole allows the first anti-detachment block to slide under the drive of the longitudinal reinforcing bar. The insertion action of the longitudinal reinforcing bar is directly converted into the locking power of the first anti-detachment block, achieving linkage locking without additional operation, simplifying the construction process; after the first anti-detachment block slides into the snap-fit ​​groove, it simultaneously cooperates with the first sliding groove and the snap-fit ​​groove to form a mechanical limit, which can effectively limit the relative displacement of longitudinally adjacent precast blocks in the longitudinal direction, avoiding the loosening and disengagement that easily occur when relying solely on gravity superposition or simple concave-convex fit.

[0041] like Figures 1-6 As shown, in one embodiment of the present invention, a precast block 1 with a panel-enclosed reinforced soil retaining wall has a first slot 11 and a first through hole 12 on its top surface. The first through hole 12 is used to accommodate longitudinal reinforcing bars, and the bottom surface of the precast block 1 has a first protrusion 13. The inner wall of the first slot 11 has a first groove 14 that communicates with the first through hole 12. The first protrusion 13 has a snap-fit ​​groove 131. A first anti-detachment block 2 is slidably connected in the first groove 14, and one end of the first anti-detachment block 2 is located in the first through hole 12.

[0042] If the prefabricated blocks 1 are arranged in a horizontal and vertical array to form a spliced ​​panel 10. In the vertical direction, in two adjacent prefabricated blocks 1, the first protrusion 13 of the lower prefabricated block 1 is embedded in the first slot 11 of the upper prefabricated block 1. At this time, the first groove 14 on the inner wall of the first slot 11 is in communication with the snap-fit ​​groove 131 on the first protrusion 13.

[0043] Its design principle is based on a mechanical locking structure to achieve a stable connection between longitudinally adjacent precast blocks 1. The workflow is as follows: When it is necessary to connect longitudinally adjacent precast blocks 1, firstly, the first protrusion 13 of the lower precast block 1 is embedded into the first slot 11 of the upper precast block 1 to complete the initial positioning and engagement; then, the longitudinal steel bar is inserted into the first through hole 12 from top to bottom. During the insertion process, the end of the longitudinal steel bar abuts against one end of the first anti-detachment block 2 located in the first through hole 12. The end face of the first anti-detachment block 2 can be an arc surface, a spherical surface, or an inclined surface, etc., which can abut against and slide against the longitudinal steel bar during the insertion process. As the longitudinal steel bar is continuously inserted, it applies a pushing force to the first anti-detachment block 2, driving the first anti-detachment block 2 to slide in the first sliding groove 14; during the sliding process, the other end of the first anti-detachment block 2 away from the longitudinal steel bar gradually slides and enters the locking groove 131 connected to the first sliding groove 14. At this time, the first anti-detachment block 2 is simultaneously locked in the first sliding groove 14 and the locking groove 131, thereby restricting the relative displacement of the two longitudinally adjacent precast blocks 1 in the longitudinal direction.

[0044] Through the above structural design, multiple mating relationships are formed between longitudinally adjacent precast blocks 1, effectively solving the problem of unstable connection caused by the lack of locking in the longitudinal connection of existing assembled panels. Specifically, the first protrusion 13 on the bottom surface of the precast block 1 is embedded in the first slot 11 on the top surface, realizing the initial positioning and fitting between longitudinally adjacent precast blocks 1, providing a foundation for the subsequent locking structure; the communication structure between the first sliding groove 14 and the first through hole 12 allows the first anti-detachment block 2 to slide under the drive of the longitudinal reinforcing bar. The insertion action of the longitudinal reinforcing bar is directly converted into the locking power of the first anti-detachment block 2, achieving linkage locking without additional operation, simplifying the construction process; after the first anti-detachment block 2 slides into the snap-fit ​​groove 131, it simultaneously cooperates with the first sliding groove 14 and the snap-fit ​​groove 131 to form a mechanical limit, which can effectively limit the relative displacement of longitudinally adjacent precast blocks 1 in the longitudinal direction, avoiding the loosening and disengagement that easily occur when relying solely on gravity superposition or simple concave-convex fit.

[0045] In some examples, such as Figures 2-6 As shown, the first anti-detachment block 2 of the precast block 1 has an abutment surface 21 at one end located in the first through hole 12. The abutment surface 21 extends downward at an incline toward the axis of the first through hole 12. When the longitudinal steel bar is inserted into the first through hole 12 from top to bottom, the end of the longitudinal steel bar contacts the inclined abutment surface 21.

[0046] Its design principle is based on the inclined plane force transmission mechanism. It uses the inclined angle of the abutment surface 21 to convert the insertion force of the longitudinal steel bar into a force that drives the first anti-detachment block 2 to slide laterally. The working process is as follows: During the process of inserting the longitudinal steel bar into the first through hole 12, its end continuously presses against the abutment surface 21. Due to the inclined setting of the abutment surface 21, the vertical thrust of the longitudinal steel bar is decomposed along the abutment surface 21 into a force perpendicular to the abutment surface 21. This force drives the first anti-detachment block 2 to slide along the first sliding groove 14 in a direction away from the first through hole 12, so that the other end of the first anti-detachment block 2 can smoothly slide into the locking groove 131, completing the locking of the longitudinally adjacent precast blocks 1.

[0047] The inclined design of the contact surface 21 enables the insertion action of the longitudinal reinforcing bar to be efficiently converted into the sliding force of the first anti-detachment block 2. Compared with the vertical contact surface, the inclined structure reduces the resistance when the longitudinal reinforcing bar is inserted, ensuring that the first anti-detachment block 2 slides stably under the drive of the longitudinal reinforcing bar, and avoiding the inability of the anti-detachment block to enter the locking groove 131 due to poor force transmission. At the same time, the inclined contact surface 21 forms a surface contact with the end of the longitudinal reinforcing bar, which disperses the contact stress and avoids damage to the local structure due to stress concentration, further ensuring the reliability of the longitudinal connection locking.

[0048] A reset surface 22 is provided at the end of the first anti-detachment block 2 away from the contact surface 21. The reset surface 22 is located on the side of the first anti-detachment block 2 near the opening of the first slide groove 14. When longitudinally adjacent precast blocks 1 are spliced ​​together, when the first protrusion 13 of the lower precast block 1 is inserted into the first slot 11 of the upper precast block 1, the side wall of the first protrusion 13 contacts the reset surface 22.

[0049] Its design principle is to use the thrust of the first protrusion 13 when it is inserted to reset the initial position of the first anti-detachment block 2. The working process is as follows: During the process of the first protrusion 13 being inserted into the first slot 11, the side wall of the first protrusion 13 gradually approaches and pushes against the reset surface 22, forcing the first anti-detachment block 2 to slide along the first groove 14 toward the first through hole 12 until one end of the first anti-detachment block 2 located in the first through hole 12 is completely returned to the first through hole 12, leaving enough sliding space for the subsequent insertion of the longitudinal steel bar and driving the first anti-detachment block 2 to lock.

[0050] The reset surface 22 ensures that the first anti-detachment block 2 is in the correct initial position during the initial splicing of adjacent longitudinal precast blocks 1. This prevents the first protrusion 13 from failing to smoothly embed into the first slot 11 due to the first anti-detachment block 2 extending excessively into the first groove 14 when not in operation, or prevents the longitudinal reinforcing bars from effectively sliding due to the first anti-detachment block 2 not returning into the first through hole 12. Reset is achieved through the natural thrust when the first protrusion 13 is embedded, requiring no additional operation, simplifying the construction process, and ensuring the smooth progress of subsequent locking steps, thereby improving splicing efficiency and structural reliability.

[0051] A limiting rod 141 is fixedly provided on the inner wall of the first slide groove 14, and the limiting rod 141 extends along the length direction of the first slide groove 14; a limiting groove 23 is opened on the side of the first anti-detachment block 2 facing the inner wall of the first slide groove 14, the length of the limiting groove 23 is adapted to the sliding stroke of the first anti-detachment block 2, and the limiting rod 141 slides through the limiting groove 23.

[0052] Its design principle is to limit the sliding range of the first anti-detachment block 2 through the sliding cooperation between the limiting rod 141 and the limiting groove 23. The working process is as follows: When the first anti-detachment block 2 slides along the first groove 14 under the drive of the longitudinal steel bar, the limiting rod 141 slides synchronously along the limiting groove 23. When one end of the first anti-detachment block 2 slides into the locking groove 131, one end of the limiting groove 23 abuts against the limiting rod 141, preventing the first anti-detachment block 2 from continuing to slide. When the first anti-detachment block 2 slides towards the first through hole 12 under the action of the reset surface 22, the other end of the limiting groove 23 abuts against the limiting rod 141, limiting the first anti-detachment block 2 from sliding excessively into the first through hole 12.

[0053] The cooperation structure between the limiting rod 141 and the limiting groove 23 strictly limits the sliding stroke of the first anti-detachment block 2, preventing the first anti-detachment block 2 from detaching from the first groove 14 due to excessive sliding, or from failing to fully enter the locking groove 131 due to insufficient sliding. This ensures that the first anti-detachment block 2 can be accurately locked between the first groove 14 and the locking groove 131 in the locked state, effectively limiting the relative displacement of longitudinally adjacent precast blocks 1. At the same time, the limiting structure provides guidance for the sliding of the first anti-detachment block 2, preventing it from deviating or getting stuck during the sliding process, ensuring the smoothness of the locking action, and further improving the stability of the longitudinal connection.

[0054] In some examples, such as Figures 4-6 As shown, when several precast blocks 1 are arranged longitudinally, the longitudinal joints of adjacent rows of precast blocks 1 are staggered to form a staggered arrangement structure. Each end of the top surface of a precast block 1 has a side slot 15, and each end of the bottom surface has a side protrusion 16. The shape of the side protrusion 16 matches the shape of the side slot 15. The side slots 15 of two horizontally adjacent precast blocks 1 are joined to form a second slot, and the side protrusions 16 of two horizontally adjacent precast blocks 1 are joined to form a second protrusion. The structure of the second slot is completely identical to that of the first slot 11, and the structure of the second protrusion is completely identical to that of the first protrusion 13.

[0055] Its design principle is to enhance the integrity of the longitudinal connection through staggered joint arrangement and the cooperation between the second slot and the second protrusion. The workflow is as follows: During the longitudinal splicing process, either the second protrusion of the upper precast block 1 can be embedded into the second slot formed by splicing two horizontally adjacent precast blocks 1 in the lower layer, or the second protrusion of the upper precast block 1 can be embedded into the first slot 11 of the lower precast block 1. Due to the staggered longitudinal joints, the cooperation position of the second slot and the second protrusion is staggered from the cooperation position of the first slot 11 and the first protrusion 13, which together constitute multiple constraints for the longitudinal connection.

[0056] The staggered joint structure avoids longitudinal joints being on the same straight line, dispersing the lateral soil pressure on the panel and preventing panel cracking caused by stress concentration. The second slot and second protrusion formed by splicing the side slots 15 and side protrusions 16 of the transversely adjacent precast blocks 1 complement the first slot 11 and first protrusion 13, increasing the contact area and number of connection points between longitudinally adjacent precast blocks 1, further restricting the relative displacement of longitudinally adjacent precast blocks 1 in the transverse and longitudinal directions, and improving the overall stiffness and deformation resistance of the spliced ​​panel 10.

[0057] In some examples, such as Figures 2-4As shown, the precast block 1 has two first through holes 12, which are symmetrically distributed along the transverse direction of the precast block 1. The side wall of the side slot 15 has a second sliding groove 17, which communicates with the first through holes 12. A second anti-detachment block 18 is slidably connected in the second sliding groove 17. One end of the second anti-detachment block 18 is located in the first through hole 12, and the other end can slide into the corresponding snap-fit ​​structure on the second protrusion.

[0058] Its design principle is to achieve synchronous locking on both sides of the lateral direction through the symmetrically distributed first through hole 12 and second anti-detachment block 18. The working process is as follows: After several precast blocks 1 are arranged in a staggered manner, when the longitudinal steel bar is inserted into the first through hole 12, its end simultaneously abuts against the first anti-detachment block 2 and the second anti-detachment block 18, driving them to slide along the first slide groove 14 and the second slide groove 17 respectively, so that the first anti-detachment block 2 enters the locking groove 131 of the first protrusion 13, and the second anti-detachment block 18 enters the locking structure of the second protrusion, thereby achieving simultaneous locking of the first protrusion 13 and the second protrusion.

[0059] The two symmetrically distributed first through holes 12 and corresponding second anti-detachment blocks 18 structures ensure balanced force on both sides of the precast block 1 in the lateral direction, avoiding force skewness of the precast block 1 caused by unilateral locking, and guaranteeing the symmetry and stability of the longitudinal connection. The cooperation between the second anti-detachment block 18 and the second protrusion further enhances the locking effect of the side connection, forming a synergy with the locking effect of the first anti-detachment block 2, restricting the relative displacement of longitudinally adjacent precast blocks 1 from multiple positions, making the longitudinal connection of the spliced ​​panel 10 more stable, and better able to resist the loads brought by soil lateral pressure and external vibration.

[0060] In some examples, such as Figure 1 , Figures 4-6 As shown, the base grid 3 is laid on the foundation surface, with one end extending upward along the inner side of the spliced ​​panel 10 and adhering to the panel, and the other end embedded in the foundation for anchoring. Several reinforcing components 4 are arranged longitudinally at intervals on the base grid 3. Each reinforcing component 4 includes a load-bearing grid 41, an enclosure 42, and a backfill layer 43. The load-bearing grid 41 is laid on top of the base grid 3, with the end away from the spliced ​​panel 10 anchored in the foundation; the enclosure 42 is located at the end of the load-bearing grid 41 near the panel, with the end of the load-bearing grid 41 folded back and covering the enclosure 42, thus fixing the enclosure 42; the backfill layer 43 is filled on top of the load-bearing grid 41, located between the enclosure 42 and the foundation, compacting and fixing the load-bearing grid 41.

[0061] Its design principle is to transfer and distribute the load through the synergistic effect of the base grid 3 and the reinforcing component 4. The workflow is as follows: the lateral pressure of the soil borne by the spliced ​​panel 10 is transferred to the base grid 3 and the reinforcing component 4, and the base grid 3 transfers part of the load to the foundation; the load-bearing grid 41 bears the local load transferred by the panel through the wrapping body 42, and transfers the load along its length to the anchor end, dispersing it to the foundation; the fill layer 43 constrains the load-bearing grid 41 to ensure that it does not displace under stress, thus ensuring the stability of the load transfer path.

[0062] The combined structure of the base grid 3 and the reinforcing components 4 effectively transfers the load borne by the spliced ​​panel 10 to the foundation, avoiding load concentration at the bottom of the panel and reducing the risk of damage due to excessive local stress. The ends of the load-bearing grid 41 are reinforced with a folded-back covering 42, enhancing the structural strength of the ends and preventing the load-bearing grid 41 from detaching from the panel under load. The inclusion of the fill layer 43 ensures a tight bond between the load-bearing grid 41 and the foundation, improving the overall load-bearing capacity of the reinforcing components 4. The longitudinal arrangement of the base grid 3 and the multi-layered reinforcing components 4 forms a three-dimensional load-bearing system, significantly improving the overall deformation resistance and stability of the retaining wall and enhancing its support effect on slopes or embankments.

[0063] In some examples, such as Figure 1 , Figures 4-6 As shown, an installation member 19 is provided on the side of the precast block 1 closest to the foundation grid 3. The installation member 19 has a structure for fixing the transverse reinforcing bars. After the transverse reinforcing bars are fixed, a gap is formed between them and the side of the precast block 1. The width of the gap is adapted to the thickness of the foundation grid 3. The end of the foundation grid 3 closest to the spliced ​​panel 10 passes through this gap and extends upward to fit the panel.

[0064] Its design principle is to limit the relative displacement between the base grid 3 and the panel through the gap structure. The working process is as follows: After the base grid 3 passes through the gap between the transverse steel bars and the precast block 1, the transverse steel bars form a vertical constraint on the base grid 3, preventing the base grid 3 from sliding up or down when under force; the side of the precast block 1 forms a lateral constraint on the base grid 3, restricting its movement away from the panel, so that the base grid 3 and the panel remain relatively fixed.

[0065] The gaps formed between the transverse reinforcing bars and the precast blocks 1 mechanically limit the movement of the foundation grid 3, preventing displacement of the foundation grid 3 relative to the spliced ​​panels 10 when the retaining wall is under stress or experiences external vibration. This ensures that the foundation grid 3 can stably transmit the load borne by the panels and guarantees the continuity of the load transmission path. This structure enhances the reliability of the connection between the foundation grid 3 and the panels, fully utilizes the anchoring effect of the foundation grid 3, further improves the overall structural stability of the retaining wall, and reduces the risk of retaining wall deformation caused by slippage of the foundation grid 3.

[0066] In some examples, such as Figure 1 , Figures 4-6 As shown, a connecting structure is provided on the side of the precast block 1 near the foundation grid 3, through which the mounting member 19 is detachably connected to the precast block 1. The connection method between the mounting member 19 and the precast block 1 ensures that the mounting member 19 can securely fix the transverse reinforcing bars and can be separated from the precast block 1 when needed.

[0067] Its design principle is to achieve flexible assembly and replacement of the mounting component 19 through detachable connection. The workflow is as follows: During the transportation or storage of precast blocks 1, the mounting component 19 is separated from the precast blocks 1 to reduce the space occupied; during the construction stage, the mounting component 19 is connected to the preset position of the precast blocks 1, and a gap is formed after fixing the transverse steel bars; when the mounting component 19 is damaged or needs to be adjusted, it can be disassembled and replaced or reinstalled.

[0068] The detachable design of the mounting component 19 facilitates the transportation and storage of the precast blocks 1, preventing damage to the mounting component 19 due to collisions during transportation. Simultaneously, the detachable structure makes replacement of the mounting component 19 more convenient. When the mounting component 19 is damaged due to stress or has problems with its fit with the transverse reinforcing bars, it is not necessary to replace the entire precast block 1; only the mounting component 19 needs to be replaced, reducing maintenance costs. Furthermore, the position or model of the mounting component 19 can be adjusted according to construction needs, enhancing construction flexibility and adapting to the fixing requirements of the foundation grid 3 under different working conditions.

[0069] In some examples, such as Figure 1 , Figures 4-6 As shown, a receiving space is formed between the side of the reinforcing component 4 near the splicing panel 10 and the splicing panel 10. The receiving space is filled with a filter layer 5, which completely fills the receiving space, and its two sides are in contact with the reinforcing component 4 and the splicing panel 10 respectively.

[0070] Its design principle is to achieve water and soil separation by utilizing the permeability of the filter layer 5. The working process is as follows: When water in the fill layer 43 permeates into the receiving space through the reinforcing component 4, the filter layer 5 allows the water to pass through and be discharged, while blocking fine particles in the fill layer 43 from entering the receiving space, preventing the loss of fine particles from causing the structure of the fill layer 43 to become loose, or from clogging the pores of the reinforcing component 4 and affecting drainage.

[0071] The filter layer 5 effectively prevents the loss of fine particles from the fill layer 43, maintains the structural integrity of the fill layer 43, and ensures that the reinforcing component 4 can be stably laid on the fill layer 43, fully exerting its load-bearing capacity. Simultaneously, the drainage function of the filter layer 5 prevents water accumulation in the containment space, preventing water from corroding the reinforcing component 4 or the interlocking panel 10, thus extending the service life of the retaining wall. The filter layer 5, filling the space between the reinforcing component 4 and the panel, also reduces friction and wear between them, making load transfer more stable and further improving the overall durability and stability of the retaining wall.
