Description

Technical Field

[0001] This application relates to the field of retaining walls, specifically a retaining wall structure with a small elevation difference. Background Technology

[0002] A retaining wall is a structure used to support and stabilize soil. It resists pressure from the soil through its own weight and structural design, ensuring the stability of roadbeds, embankments, or mountains. Retaining wall devices are widely used in various engineering projects, such as road construction, bridge connections, tunnel entrance reinforcement, anti-skid protection, land reclamation, and flood control.

[0003] Currently, retaining walls are typically constructed using retaining wall formwork and concrete pouring to achieve strong load-bearing capacity. However, in environments with small elevation differences (within 1.5m of the elevation difference between the two sides of the retaining wall), the soil pressure on the retaining wall is relatively small. Using retaining wall formwork and concrete pouring results in significant performance waste, and the method of constructing retaining walls using retaining wall formwork and concrete pouring is time-consuming and inefficient. Utility Model Content

[0004] To address the problem of low construction efficiency in existing technologies, this utility model provides a retaining wall structure with small elevation differences.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a retaining wall structure with small elevation difference, characterized in that it includes:

[0007] The foundation layer is topped with a brick wall, which consists of multiple stacked permeable bricks with a mortar layer between adjacent sets of permeable bricks. A top beam is installed on the top of the brick wall. Multiple stepped layers are arranged vertically on both the front and back sides of the brick wall. The bottom width of the brick wall is greater than the top width. A baffle is fixedly installed on the outer edge of each set of stepped layers on the front side of the brick wall. A green trough is formed between the baffle and the brick wall. The green trough is filled with planting soil and plant seeds. Multiple sets of partitions are fixedly installed on one side of the baffle along the length direction.

[0008] Preferably, the brick wall is provided with multiple sets of drainage components at intervals along the vertical direction. Each set of drainage components includes multiple sets of drainage pipes arranged at intervals along the left and right directions. The drainage pipes penetrate the brick wall. Through the multiple sets of drainage pipes arranged on the brick wall, rainwater in the soil behind the brick wall can be discharged to the outside of the brick wall through infiltration, thus preventing rainwater from remaining in the soil behind the brick wall.

[0009] Preferably, the drainage pipe has multiple sets of seepage holes spaced circumferentially on a section behind the brick wall. Geotextile is fitted over the section of the drainage pipe with the seepage holes. The multiple sets of seepage holes on the drainage pipe behind the brick wall allow rainwater in the soil to flow into the drainage pipe through each set of seepage holes and then be discharged. The geotextile fitted over the drainage pipe also covers the seepage holes, preventing soil from entering the drainage pipe through the seepage holes and ensuring the stability of the soil.

[0010] Preferably, the side of the baffle away from the brick wall is provided with an overflow hole that connects to the greening trough. By providing an overflow hole on the baffle, when rainwater accumulates in the greening trough to the height of the overflow hole during rainy weather, excess rainwater will flow out along the overflow hole, thus preventing excessive rainwater in the greening trough.

[0011] Preferably, the interval between two vertically adjacent sets of stepped layers is h, 500≤h≤550mm. By reasonably setting the height interval between the stepped layers, the brick wall has good strength to block the soil.

[0012] Preferably, multiple sets of fixing piles are fixedly installed at intervals at the bottom of the cushion layer. The fixing piles are formed by concrete pouring. The multiple sets of fixing piles further stabilize the cushion layer and the brick wall, thereby improving the strength of the overall structure.

[0013] Preferably, the top surface of the top beam is inclined, wherein the height of the front side of the top beam is less than the height of the rear side of the top beam, so that when it rains, rainwater on the top beam can flow along the inclined top surface to the front side of the brick wall, preventing rainwater from flowing into the soil on the rear side and ensuring the stability of the soil.

[0014] The advantages of adopting the above technical solution are:

[0015] This invention includes a foundation layer, on top of which is a brick wall. The brick wall comprises multiple stacked permeable bricks, with a mortar layer between adjacent sets of permeable bricks. A top beam is provided at the top of the brick wall. Multiple stepped layers are arranged vertically on both the front and rear sides of the brick wall. The bottom width of the brick wall is greater than the top width. A baffle is fixedly installed along the outer edge of each set of stepped layers on the front side of the brick wall. A greening trough is formed between the baffle and the brick wall, and the greening trough is filled with planting soil and plant seeds. Multiple partitions are fixedly installed along the length of one side of the baffle within the greening trough. This structure uses permeable bricks and mortar to construct brick walls on sites with small elevation differences, greatly improving the construction period. Furthermore, the baffles and partitions allow for greening operations on the brick wall, enhancing its aesthetic appeal. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1-3 As shown in the figure, this utility model embodiment discloses a retaining wall structure with a small elevation difference, including a cushion layer 1, a brick wall 2 on top of the cushion layer 1, the brick wall 2 including multiple sets of permeable bricks stacked together, a mortar layer between two adjacent sets of permeable bricks, a top beam 3 on top of the brick wall 2, multiple stepped layers 201 spaced vertically on both the front and rear sides of the brick wall 2, the bottom width of the brick wall 2 being greater than the top width, a baffle 4 fixedly installed on the outer edge of each set of stepped layers 201 on the front side of the brick wall 2, a greening trough 202 formed between the baffle 4 and the brick wall 2, the greening trough 202 being filled with planting soil and plant seeds, and multiple sets of partitions 401 fixedly installed on one side of the baffle 4 along the length direction within the greening trough 202.

[0023] In at least one embodiment, the brick wall 2 is provided with multiple sets of drainage components at intervals along the vertical direction. Each set of drainage components includes multiple sets of drainage pipes 5 arranged at intervals along the left and right directions. The drainage pipes 5 penetrate the brick wall 2. By arranging multiple sets of drainage pipes 5 on the brick wall 2, rainwater in the soil behind the brick wall 2 can be discharged to the outside of the brick wall 2 through infiltration and drainage pipes 5, thus preventing rainwater from remaining in the soil behind the brick wall 2.

[0024] In at least one embodiment, a drainage pipe 5 is provided with multiple sets of seepage holes 501 at circumferential intervals on a section of the drainage pipe 5 behind the brick wall 2. A geotextile 6 is fitted over a section of the drainage pipe 5 with the seepage holes 501. By providing multiple sets of seepage holes 501 on the drainage pipe 5 behind the brick wall 2, rainwater in the soil can flow into the drainage pipe 5 along each set of seepage holes 501 and then be discharged. Furthermore, the geotextile 6 fitted over the drainage pipe 5 can cover the seepage holes 501, preventing soil in the soil from entering the drainage pipe 5 through the seepage holes 501, thus ensuring the stability of the soil.

[0025] In at least one embodiment, the side of the baffle 4 away from the brick wall 2 is provided with an overflow hole that connects to the greening trough 202. By providing an overflow hole on the baffle 4, when rainwater accumulates in the greening trough 202 to the height of the overflow hole during rainy weather, excess rainwater will flow out along the overflow hole, thus preventing excessive rainwater in the greening trough 202.

[0026] In at least one embodiment, the interval between two vertically adjacent sets of stepped layers 201 is h, 500≤h≤550mm. By reasonably setting the height interval between the stepped layers 201, the brick wall 2 is guaranteed to have good strength to block the soil.

[0027] In at least one embodiment, multiple sets of fixing piles 101 are fixedly provided at intervals at the bottom of the cushion layer 1. The fixing piles 101 are formed by concrete pouring. The multiple sets of fixing piles 101 further stabilize the cushion layer 1 and the brick wall 2, thereby improving the strength of the overall structure.

[0028] In at least one embodiment, the top surface of the top beam 3 is inclined, wherein the height of the front side of the top beam 3 is less than the height of the rear side of the top beam 3, so that when it rains, rainwater on the top beam 3 can flow along the inclined top surface to the front side of the brick wall 2, preventing rainwater from flowing into the soil on the rear side and ensuring the stability of the soil.

[0029] When performing retaining wall work on sites with a small elevation difference of less than 1.5m, workers first compact the foundation, then dig trenches on the foundation. A concrete subbase 1 is then placed within the trench. Next, permeable bricks and mortar are laid on the subbase 1 to form a brick wall 2. The rear side of the brick wall 2 is aligned with the higher side of the soil. Stepped layers 201 are provided on both the front and rear sides of the brick wall 2, with the bottom width greater than the top width, giving the brick wall 2 good stability and effective resistance to the higher side of the soil. Finally, a top beam 3, also made of concrete, is installed on top of the brick wall 2 to further enhance its stability. After the mortar between the permeable bricks reaches the design strength, sand and soil are backfilled to the elevation on the back side of the brick wall 2. Finally, the brick wall 2 is formed by laying permeable bricks and mortar, thus retaining soil for small elevation differences, which greatly shortens the construction period and improves construction efficiency. Furthermore, a baffle 4 is fixedly installed at the stepped layer 201 on the front side of the brick wall 2. The baffle 4 forms a greening trough 202, which is filled with planting soil and plant seeds, thus carrying out overall greening of the brick wall 2 and improving its aesthetics. Moreover, multiple sets of partitions 401 set on the baffle 4 can divide the greening trough 202, allowing for the planting of different types of plants in separate areas, thereby improving the aesthetics of the green area.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
