Description
Technical Field
[0001] This utility model relates to the field of retaining wall reinforcement technology, and in particular to a retaining wall reinforcement structure. Background Technology
[0002] Retaining wall reinforcement structures are structural measures and additional components installed on the basis of the original retaining wall to further enhance its stability and load-bearing capacity. They are designed to make up for the deficiencies in the strength, stiffness or stability of the retaining wall itself. The application of retaining wall reinforcement structures can improve the reliability of the retaining wall in complex working conditions and harsh environments and extend its service life.
[0003] A search revealed Chinese patent publication number CN216339664U, which discloses a reinforced structure for underwater retaining walls. The structure includes precast piles spaced apart on the water-facing side of the retaining wall, underwater concrete on top of the precast piles, cast-in-place concrete on top of the underwater concrete, a drainage pad between the underwater concrete and the retaining wall, and anchor bars connecting the cast-in-place concrete and the underwater concrete. The drainage pad is located at the outlet of a drainage pipe within the retaining wall. This utility model uses a reinforced structure to improve the stability of existing retaining walls, addresses the increased bearing capacity required by new structures through precast pile foundations, and improves the drainage channel of the retaining wall through the drainage pad. It solves most of the retaining wall heightening and reinforcement needs encountered in production practice. The construction process is simple, the investment is low, and it has almost no impact on structures behind the wall. However, in actual use, due to long-term water erosion, the soil behind the retaining wall may move and deform, leading to localized stress concentration and causing damage and collapse of the retaining wall. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a retaining wall reinforcement structure, which aims to improve the problem in the prior art where the soil behind the retaining wall moves and deforms due to long-term water erosion, and the local stress concentration causes the retaining wall to be damaged and collapse.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a retaining wall reinforcement structure, comprising a retaining wall body, a reinforcement mechanism provided on the rear side of the retaining wall body, the reinforcement mechanism being used to reinforce the retaining wall body, a base being fixedly connected to the bottom of the retaining wall body, a positioning mechanism being provided inside the reinforcement mechanism, a drainage mechanism being provided inside the retaining wall body, the drainage mechanism being used to drain the soil, and a protective mechanism being provided on the front side of the retaining wall body;
[0006] The reinforcement mechanism includes multiple embedded columns, the front sides of which are equidistantly fixed to the rear side of the retaining wall body. A geogrid is provided on the rear side of the retaining wall body. Multiple fixing blocks are equidistantly fixed to the inner wall of the geogrid. The inner walls of the fixing blocks are slidably connected to the outer walls of the corresponding embedded columns. A screw is slidably connected to the inner walls of the fixing blocks. A threaded groove is provided on the rear side of each embedded column. The front ends of the screws penetrate the rear ends of the corresponding fixing blocks and are threaded to the inner wall of the corresponding threaded groove. Shotcrete is fixedly connected to the rear side of the geogrid.
[0007] The above technical solution involves first installing multiple pre-embedded columns to provide support for subsequent component installation. The geogrid is then fitted onto the pre-embedded columns using fixing blocks, allowing it to slide along the outer wall of the columns to adjust its position to meet different reinforcement requirements. Once adjusted, a screw is passed through the fixing block and screwed into the threaded groove on the back of the pre-embedded column, thus firmly fixing the geogrid to the back of the retaining wall. Finally, concrete is sprayed onto the back of the geogrid, filling the gaps in the geogrid to form a robust reinforcement layer. This strengthens the connection between the retaining wall and the soil, enhancing the retaining wall's ability to resist soil pressure and deformation.
[0008] As a further description of the above technical solution:
[0009] The protective mechanism includes two connecting blocks. The rear sides of the two connecting blocks are respectively fixedly connected to the left and right ends of the front side of the retaining wall body. The front side of each of the two connecting blocks is provided with a locking groove. The inner wall of each of the two locking grooves is slidably connected with a T-shaped locking block. The front side of each of the two T-shaped locking blocks is fixedly connected with the same protective panel. The bottom of the inner wall of each of the two locking grooves is fixedly connected with a limiting block. The top of each of the two limiting blocks is respectively abutted against the bottom of the corresponding T-shaped locking block. The opposite sides of the two connecting blocks are provided with fixing components.
[0010] The above technical solution involves aligning the T-shaped locking block with the locking groove on the front side of the connecting block and sliding it along the groove to quickly and easily position the protective panel in front of the retaining wall body. When the T-shaped locking block slides down to the limiting block, the limiting block fits against the bottom of the T-shaped locking block, restricting its further descent and ensuring the vertical stability of the protective panel. Finally, the T-shaped locking block is further secured by the fixing component on the opposite side of the connecting block, thereby ensuring the protective panel is firmly installed, enhancing the retaining wall's resistance to erosion and corrosion, and protecting the retaining wall body.
[0011] As a further description of the above technical solution:
[0012] The drainage mechanism includes multiple drainage branch pipes I, the outer walls of which are fixedly connected at equal intervals to the top of the inner wall of the retaining wall body, and multiple drainage branch pipes II are fixedly connected at equal intervals to the bottom of the inner wall of the retaining wall body. The front ends of the multiple drainage branch pipes I and the multiple drainage branch pipes II are fixedly connected to corresponding L-shaped drainage pipes, and the outer walls of the multiple L-shaped drainage pipes are fixedly connected at equal intervals to the inner wall of the retaining wall body.
[0013] The above technical solution involves multiple drainage branch pipes located at the top of the inner wall of the retaining wall, which collect water from the soil at higher elevations. Meanwhile, multiple drainage branch pipes equidistantly distributed at the bottom of the inner wall collect water from the soil at lower elevations. The collected water flows into L-shaped drainage pipes fixedly connected to their front ends. The outer walls of the L-shaped drainage pipes are fixed to the inner wall of the retaining wall, guiding the water out of the retaining wall. This layout effectively lowers the water level in the soil behind the wall, reduces the impact of water pressure on the retaining wall, and ensures the stability of the retaining wall.
[0014] As a further description of the above technical solution:
[0015] The positioning mechanism includes multiple positioning blocks, one side of which is fixedly connected to the other side of the corresponding threaded groove. Positioning grooves are provided on both the left and right sides of the inner wall of the fixed block, and the inner walls of the multiple positioning grooves are slidably connected to the outer walls of the corresponding positioning blocks.
[0016] The above technical solution allows for precise positioning of the fixing block by sliding its inner wall positioning groove along the outer wall of the positioning block during installation, ensuring accurate installation of each component of the reinforcement mechanism.
[0017] As a further description of the above technical solution:
[0018] The fixing assembly includes multiple screws, one end of each screw is slidably connected to the inner wall of the other side of the corresponding connecting block. Multiple threaded grooves are equally spaced on the opposite sides of the two T-shaped engaging blocks. One end of each screw penetrates the other side of the corresponding connecting block and is threaded to the inner wall of the corresponding threaded groove. Washers are slidably connected to the outer walls of each screw, and one side of each washer is abutted against the other side of the corresponding connecting block.
[0019] The above technical solution involves first sliding one end of the screw two to the inner wall of the other side of the connecting block and adjusting its position. Then, the screw is passed through the connecting block and screwed into the threaded groove two on the T-shaped locking block to achieve a tight connection between the two. A washer is placed on the outer wall of the screw two and fits against the connecting block to increase friction and prevent the screw two from loosening, thus ensuring the protective panel is securely installed.
[0020] As a further description of the above technical solution:
[0021] The rear ends of the plurality of drainage branch pipes one and the plurality of drainage branch pipes two are fixedly connected to a shell, and the inner walls of the plurality of shells are fixedly connected to a geotextile filter.
[0022] The above technical solution uses geotextile filters to prevent soil particles from entering, ensuring smooth drainage, preventing pipe blockage, and guaranteeing the stable operation of the drainage system.
[0023] As a further description of the above technical solution:
[0024] A cross-shaped groove is provided on the right side of the retaining wall body, and a cross-shaped concrete block is fixedly connected to the left side of the retaining wall body. The outer wall of the cross-shaped concrete block is in contact with the inner wall of the cross-shaped groove.
[0025] The above technical solution involves fitting the cross-shaped concrete block on the left side of one retaining wall body to the cross-shaped groove on the right side of the other retaining wall body, thereby enhancing the stability of the connection between adjacent retaining walls.
[0026] As a further description of the above technical solution:
[0027] The rear side of the retaining wall body is designed to be inclined, and concrete pads are fixedly connected to the four corners of the bottom of the base.
[0028] Through the above technical solutions: the inclined design of the rear side of the retaining wall facilitates the rapid drainage of water behind the wall, reduces water pressure, and the concrete pad at the corner of the base increases the contact area with the ground, disperses pressure, and improves the stability of the retaining wall.
[0029] This utility model has the following beneficial effects:
[0030] 1. In this utility model, when the main body of the retaining wall is eroded by water flow, the pre-fixed embedded columns on the rear side are connected to the geogrid, and after sliding positioning and screw fastening, the geogrid is filled with sprayed concrete to form a reinforcement layer, which restrains the soil and disperses the pressure. The drainage branch pipe inside the main body of the retaining wall collects the accumulated water and discharges it through the L-shaped drainage pipe to lower the water level. The positioning block and the positioning groove of the fixing block in the positioning mechanism cooperate to ensure the stability of the geogrid. The reinforcement mechanism continues to play its role and ensures the stability and safety of the main body of the retaining wall.
[0031] 2. In this utility model, first align the T-shaped locking blocks on both sides with the locking groove of the connecting block, and push them along the groove. After they are in place, the bottom limiting block of the groove fits with the bottom of the T-shaped locking block to ensure stability. Then, pass the screw through the connecting block and screw it into the threaded groove of the T-shaped locking block. At the same time, put on a washer to increase friction and prevent loosening, so that the protective panel is firmly installed, enhancing the retaining wall's resistance to erosion and corrosion. If the panel is damaged, it can be disassembled and replaced by unscrewing the screw, reducing maintenance costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a retaining wall reinforcement structure, including a retaining wall body 1, which serves as the main load-bearing structure of the retaining wall, bearing pressure from the soil and external environment. A reinforcement mechanism 2 is provided on the rear side of the retaining wall body 1 to enhance its stability and improve its ability to resist external forces. The reinforcement mechanism 2 includes multiple embedded columns 201, whose front sides are equidistantly fixedly connected to the rear side of the retaining wall body 1, providing support and positioning for subsequent installation. A geogrid 202 is provided on the rear side of the retaining wall body 1, which enhances the connection between the soil and the retaining wall and disperses soil pressure. Multiple fixing blocks 203 are equidistantly fixedly connected to the inner wall of the geogrid 202 to connect the geogrid 202 to the embedded columns 201. The inner walls of the geogrid 202 and the corresponding outer walls of the embedded columns 201 are slidably connected to each other, facilitating the adjustment of the position of the geogrid 202. Screws 204 are slidably connected to the inner walls of the multiple fixing blocks 203 to fix the relative positions of the geogrid 202 and the embedded columns 201. Threaded grooves 205 are provided on the rear sides of the multiple embedded columns 201, which cooperate with the screws 204 to achieve a tight connection. The front ends of the screws 204 penetrate the rear ends of the corresponding fixing blocks 203 and are threaded onto the inner walls of the corresponding threaded grooves 205, thus fixing the geogrid 202 to the embedded columns 201. Shotcrete 206 is fixedly connected to the rear side of the geogrid 202 to fill the gaps in the geogrid, forming a reinforcement layer that enhances the retaining wall's erosion resistance and confines the soil. The retaining wall body 1... A base 4 is fixedly connected to the bottom to increase the contact area between the retaining wall and the foundation, thereby improving the bearing capacity of the foundation. The reinforcement mechanism 2 has a positioning mechanism 6 inside to ensure accurate installation of each component. The positioning mechanism 6 includes multiple positioning blocks 601, which cooperate with the fixing block 203 for positioning. One side of each positioning block 601 is fixedly connected to the other side of the corresponding threaded groove 205, serving both positioning and connection functions. Positioning grooves 602 are provided on both the left and right sides of the inner wall of the fixing block 203, cooperating with the positioning blocks 601 to restrict the position of the fixing block 203. The inner walls of the multiple positioning grooves 602 are slidably connected to the outer walls of the corresponding positioning blocks 601, facilitating installation and ensuring positional accuracy. A drainage mechanism 5 is installed inside the retaining wall body 1 to drain accumulated water from the soil. To reduce soil water pressure, the drainage mechanism 5 includes multiple drainage branch pipes 501 to collect accumulated water in the soil near the top of the inner wall of the retaining wall body 1. The outer walls of the multiple drainage branch pipes 501 are equidistantly fixed to the top of the inner wall of the retaining wall body 1, achieving effective collection of the accumulated water at the top. Multiple drainage branch pipes 502 are equidistantly fixed to the bottom of the inner wall of the retaining wall body 1 to collect accumulated water in the soil near the bottom of the inner wall of the retaining wall body 1. The front ends of the multiple drainage branch pipes 501 and multiple drainage branch pipes 502 are all fixedly connected to corresponding L-shaped drainage pipes 503 to discharge the collected water from the retaining wall body 1. The outer walls of the multiple L-shaped drainage pipes 503 are equidistantly fixed to the inner wall of the retaining wall body 1 to ensure the stability of the drainage path. A protective mechanism 3 is provided on the front side of the retaining wall body 1.Enhance the retaining wall's resistance to erosion and corrosion;
[0042] Specifically, multiple embedded columns 201 are pre-fixed to the rear side of the retaining wall body 1. Water erosion will cause the soil behind the wall to move and deform. At this time, the geogrid 202 is slidably positioned on the embedded columns 201 by fixing blocks 203, and then screws 204 are screwed into the threaded grooves 205 on the rear side of the embedded columns 201 to tightly fix the geogrid 202. Shotcrete 206 is evenly sprayed into the geogrid 202, filling the gaps and forming an integral reinforcement layer. This enhances the erosion resistance of the retaining wall body 1, restrains the soil, prevents its movement and deformation, improves the stability of the retaining wall, strengthens the connection between the soil and the retaining wall, disperses the pressure generated by water erosion, avoids local stress concentration, and thus prevents damage to the retaining wall due to soil deformation. Water erosion will increase the soil moisture content, and drainage branch pipes... 501 is located at the top of the inner wall of the retaining wall body 1, collecting accumulated water in the soil near the top. Drainage branch pipe 502 is located at the bottom of the inner wall of the retaining wall body 1, responsible for collecting accumulated water near the bottom. The accumulated water is discharged through L-shaped drainage pipe 503, effectively reducing the water level in the soil, reducing the pressure of water on the retaining wall, and preventing soil movement and deformation due to excessive water pressure, thus avoiding erosion of the retaining wall body 1. The positioning mechanism 6 ensures the stable operation of the reinforcement mechanism 2. During the water flow scouring process, the positioning block 601 and the positioning groove 602 on the inner wall of the fixing block 203 closely cooperate to ensure that the fixing block 203 is accurately positioned on the pre-embedded column 201, so that the geogrid 202 is always firmly installed. The reinforcement mechanism 2 continues to play a reinforcing role, effectively resisting the damage caused by water flow scouring to the retaining wall, and ensuring the stability and safety of the retaining wall body 1.
[0043] Reference Figure 1 , Figure 2 and Figure 5The protective mechanism 3 includes two connecting blocks 301, which are used to connect to the retaining wall body 1. The rear sides of the two connecting blocks 301 are respectively fixedly connected to the left and right ends of the front side of the retaining wall body 1, so that the protective mechanism 3 is stably installed on the front side of the retaining wall body 1. The front side of each of the two connecting blocks 301 is provided with a locking groove 302, which provides a sliding track for the T-shaped locking block 303. The inner walls of the two locking grooves 302 are slidably connected with T-shaped locking blocks 303, which are used to connect the protective panel 304 and... Installation and positioning are achieved by sliding within the groove. The front sides of both T-shaped locking blocks 303 are fixedly connected to the same protective panel 304. The protective panel 304 enhances the retaining wall's erosion and corrosion resistance. Limiting blocks 305 are fixedly connected to the bottom of the inner walls of both locking grooves 302. The limiting blocks 305 restrict the downward movement of the T-shaped locking blocks 303. The tops of the two limiting blocks 305 respectively abut against the bottoms of the corresponding T-shaped locking blocks 303, ensuring the vertical stability of the protective panel 304. The two connecting... Each of the two T-shaped locking blocks 301 has a fixing component 306 on its opposite side. The fixing component 306 is used to further fix the protective panel 304. The fixing component 306 includes multiple screws 3061. The screws 3061 are used to pass through the connecting block 301 and be threadedly connected to the T-shaped locking block 303 to achieve fastening. One end of each screw 3061 is slidably connected to the inner wall of the other side of the corresponding connecting block 301 to facilitate adjustment of the screw position during installation. Multiple screws are equally spaced on the opposite sides of the two T-shaped locking blocks 303. The groove 3063, in conjunction with the screw 3061, achieves a fastening connection. One end of each screw 3061 passes through the other side of the corresponding connecting block 301 and is threaded onto the inner wall of the corresponding groove 3063, thus firmly fixing the protective panel 304. Each screw 3061 has a washer 3062 slidably connected to its outer wall. The washer 3062 is used to increase friction and prevent the screws from loosening. One side of each washer 3062 is in contact with the other side of the corresponding connecting block 301 to enhance the fixing effect.
[0044] Specifically, the T-shaped engaging blocks 303 on both sides of the protective panel 304 are aligned with the engaging grooves 302 of the two connecting blocks 301, and slowly pushed along the grooves. As the T-shaped engaging blocks 303 slide within the engaging grooves 302, until the protective panel 304 reaches the predetermined position, the limiting block 305 at the bottom of the inner wall of the engaging groove 302 comes into play, fitting against the bottom of the T-shaped engaging blocks 303 to prevent them from sliding further down, thus ensuring the vertical stability of the protective panel 304. Multiple screws 3061 are then inserted through one end... Through the connecting block 301, screw it into the threaded groove 3063 on the opposite side of the T-shaped locking block 303. At the same time, put the washer 3062 on the outer wall of the screw 3061 so that one side of it fits against the other side of the connecting block 301, increasing the friction and preventing the screw 3061 from loosening. The protective panel 304 is firmly installed on the front side of the retaining wall body 1, which enhances the retaining wall's resistance to erosion and corrosion. If the protective panel 304 is damaged in the future, it can be easily disassembled and replaced by simply unscrewing the screw 3061, reducing maintenance difficulty and cost.
[0045] Reference Figure 1 , Figure 5 and Figure 6 Multiple drainage branch pipes 501 and 502 are all fixedly connected to a housing 7 at their rear ends. The housing 7 protects the internal geotextile screen 8 and provides installation support. The inner walls of the multiple housings 7 are all fixedly connected to geotextile screens 8. The geotextile screens 8 prevent soil particles from entering the drainage branch pipes and avoid blockage. A cross groove 9 is provided on the right side of the retaining wall body 1. The cross groove 9 is used to cooperate with the cross concrete block 10 to enhance the connection stability between adjacent retaining wall bodies 1. A cross concrete block 10 is fixedly connected to the left side of the retaining wall body 1. The cross concrete block 10 can be embedded in the cross groove 9 to achieve precise splicing between the retaining wall bodies 1. The outer wall of the cross concrete block 10 fits into the inner wall of the cross groove 9, so that the adjacent retaining wall bodies 1 are tightly connected and can jointly bear external forces. The rear side of the retaining wall body 1 is inclined. This inclined design helps to guide the water behind the wall to flow quickly to the drainage mechanism 5. Concrete pads 11 are fixedly connected at the four corners of the bottom of the base 4. The concrete pads 11 can increase the contact area between the base 4 and the foundation, disperse pressure, and improve the overall stability of the retaining wall.
[0046] Specifically, the outer shell 7 protects the internal geotextile screen 8 and provides installation support. The geotextile screen 8 prevents soil particles from entering the drainage branch pipe and avoids blockage. The cross concrete block 10 can be embedded in the cross groove 9 to achieve precise splicing between the retaining wall bodies 1, enhance the connection stability between adjacent retaining wall bodies 1, and jointly bear external forces. The rear side of the retaining wall body 1 is designed with an inclination. This inclination design helps to guide the water behind the wall to flow quickly to the drainage mechanism 5. The concrete pad 11 can increase the contact area between the base 4 and the foundation and disperse the pressure.
[0047] Working principle: When the retaining wall body 1 is subjected to water erosion, multiple pre-embedded columns 201 are fixed to the rear side of the retaining wall body 1. The water erosion will cause the soil behind the wall to move and deform. At this time, the geogrid 202 is slidably positioned on the pre-embedded columns 201 by fixing blocks 203. Then, screws 204 are screwed into the threaded grooves 205 on the rear side of the pre-embedded columns 201 to firmly fix the geogrid 202. Shotcrete 206 is evenly sprayed into the geogrid 202 to fill the gaps in the grid and form an integral reinforcement layer. This not only enhances the erosion resistance of the retaining wall body 1, but also restrains the soil, prevents its movement and deformation, improves the stability of the retaining wall, strengthens the connection between the soil and the retaining wall, disperses the pressure generated by the water erosion, avoids local stress concentration, and thus prevents the retaining wall from being damaged by soil deformation. The water erosion will increase the water content of the soil. In addition, drainage branch pipe 1 501 is located at the top of the inner wall of the retaining wall body 1, collecting water accumulated in the soil near the top. Drainage branch pipe 2 502 is located at the bottom of the inner wall of the retaining wall body 1, responsible for collecting water accumulated near the bottom. The water is discharged through L-shaped drainage pipe 503, effectively reducing the water level in the soil, reducing the pressure of water on the retaining wall, and preventing soil movement and deformation due to excessive water pressure, which could erode the retaining wall body 1. The positioning mechanism 6 ensures the stable operation of the reinforcement mechanism 2. During the water flow scouring process, the positioning block 601 and the positioning groove 602 on the inner wall of the fixing block 203 closely cooperate to ensure that the fixing block 203 is accurately positioned on the pre-embedded column 201, so that the geogrid 202 is always firmly installed. The reinforcement mechanism 2 continues to play a reinforcing role, effectively resisting the damage caused by water flow scouring to the retaining wall, and ensuring the stability and safety of the retaining wall body 1.
[0048] Furthermore, when installing the protective panel 304, align the T-shaped engaging blocks 303 on both sides of the protective panel 304 with the engaging grooves 302 of the two connecting blocks 301, and slowly push them along the grooves. As the T-shaped engaging blocks 303 slide within the engaging grooves 302 until the protective panel 304 reaches the predetermined position, the limiting block 305 at the bottom of the inner wall of the engaging groove 302 comes into play, fitting against the bottom of the T-shaped engaging blocks 303 to prevent them from sliding further down, thus ensuring the vertical stability of the protective panel 304. This allows the multiple screws 302 to be tightened. One end of screw 61 passes through connecting block 301 and is screwed into threaded groove 3063 on the opposite side of T-shaped locking block 303. At the same time, a washer 3062 is fitted on the outer wall of screw 3061 so that one side of it fits against the other side of connecting block 301, increasing friction and preventing screw 3061 from loosening. Protective panel 304 is firmly installed on the front side of retaining wall body 1, enhancing the retaining wall's resistance to erosion and corrosion. If protective panel 304 is damaged in the future, it can be easily disassembled and replaced by simply unscrewing screw 3061, reducing maintenance difficulty and cost.
