Technical Field
[0001] This utility model relates to the field of slope construction technology, specifically to a slope retaining wall based on corrugated pipes. Background Technology
[0002] Corrugated pipe retaining walls are crucial structures for preventing soil collapse and protecting engineering safety. Traditional retaining walls, such as gravity retaining walls or cantilever retaining walls, often face hydrostatic pressure problems caused by slope water accumulation. These retaining walls typically have transverse drainage holes to drain water behind the wall. However, relying solely on transverse drainage holes has significant shortcomings: First, the drainage holes are easily blocked by soil particles, resulting in a significant decrease in drainage efficiency over long-term use, leading to water pressure accumulation behind the wall and increasing the wall's load; second, a single transverse drainage channel has limited capacity to conduct deep groundwater; and third, the continuous effect of hydrostatic pressure not only increases the risk of wall overturning but may also accelerate the deterioration of the wall materials.
[0003] To improve drainage efficiency, existing technologies attempt to install vertical drainage pipes (such as PVC pipes or corrugated pipes) behind retaining walls. However, these drainage pipes are usually installed independently of the main retaining wall structure, serving only an auxiliary drainage function and failing to form an effective collaborative stress-bearing mechanism with the retaining wall. Their structural function is singular, contributing little to enhancing the overall stability of the retaining wall or improving the stress distribution of the soil behind it. Especially when dealing with external forces such as rainwater erosion, earthquakes, or uneven foundation settlement, traditional retaining wall structures are insufficient in effectively dispersing stress, preventing landslides, and improving structural toughness.
[0004] Furthermore, existing retaining wall structures still have room for optimization in terms of foundation bearing capacity and material utilization efficiency when facing complex geological conditions or requiring higher stability. Utility Model Content
[0005] To address the shortcomings of existing technologies, the present invention aims to provide a corrugated pipe-based slope retaining wall that can more efficiently and collaboratively solve drainage problems, significantly reduce the hazards of hydrostatic pressure, and enhance the interaction between the retaining wall and the soil through structural design, thereby improving overall stability and deformation resistance and effectively dispersing soil stress.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a slope retaining wall based on a corrugated pipe, comprising: The wall panel is installed vertically and has multiple drainage holes that run through it from front to back. A front extension plate is disposed on the front wall of the wall panel and near the bottom of the wall panel; A rear support plate is disposed on the rear wall of the wall panel and near the bottom of the wall panel; Anchor blocks, disposed on the bottom surface of the wall panel, are used for anchoring to the ground; and There are multiple corrugated pipes, which are arranged along the width direction of the wall panel and closely attached to the front wall of the wall panel. The bottom end of the corrugated pipe passes through the front extension plate and is flush with the bottom end of the anchor block, and the top end of the corrugated pipe is flush with the top end of the wall panel.
[0007] Furthermore, it also includes a reinforcing cage, which is embedded inside the corrugated pipe and is set at the same height as the corrugated pipe.
[0008] Furthermore, it also includes a limiting plate assembly, which includes two limiting plates, which are respectively disposed in the middle and top of the front wall of the wall panel, and the upper end of the reinforcing cage passes through the two limiting plates in sequence.
[0009] Furthermore, it also includes a reinforcing support structure, which is supported between the rear wall of the wall panel and the rear support plate.
[0010] Furthermore, the reinforcing support structure includes a support block supported between the rear wall of the wall panel and the rear support plate, and the width of the support block on the side away from the wall panel gradually decreases from bottom to top.
[0011] Furthermore, the side of the support block away from the wall panel is stepped.
[0012] Furthermore, the wall panel, front extension plate, rear support plate, and anchor block are all precast concrete structures.
[0013] Furthermore, the connection points between the wall panel and the front extension plate and the rear support plate are provided with reinforcing ribs.
[0014] The beneficial effects of this utility model are: The above-mentioned corrugated pipe-based slope retaining wall has the following beneficial effects: 1. Highly efficient and coordinated drainage reduces the hazards of hydrostatic pressure. Multiple drainage holes running through the front and back of the wall panel, together with multiple corrugated pipes installed close to the front wall of the wall panel, work together to form a three-dimensional drainage channel that combines horizontal and vertical directions. This structure can not only quickly drain water accumulated on the slope and avoid the problem of easy clogging of traditional single drainage holes, but also effectively divert deep groundwater and significantly reduce the risk of damage to the retaining wall caused by hydrostatic pressure behind the wall.
[0015] 2. Enhance the interaction force between the retaining wall and the soil, and improve overall stability. The corrugated structure of the corrugated pipe can significantly increase the friction between the soil and the pipe, effectively preventing the soil from landslides or collapses under the action of external forces such as rainwater erosion or earthquakes. At the same time, the corrugated pipe is set close to the wall panel to form a longitudinal load-bearing component, which shares the soil pressure with the main body of the retaining wall and improves the overall overturning resistance of the structure.
[0016] 3. Improves stress distribution and extends service life Corrugated pipes have a certain degree of elasticity and toughness, which can absorb and disperse stress in the soil, reduce the local load on the retaining wall, avoid wall cracking or deformation caused by stress concentration, and thus extend the service life of the retaining wall.
[0017] 4. Simple structure and convenient construction The retaining wall consists of wall panels, front extension panels, rear support panels, anchor blocks, and corrugated pipes. The connections between the components are clearly defined. During installation, only the anchor blocks need to be anchored and the corrugated pipes need to be fixed. The construction process is simple and can effectively shorten the construction period.
[0018] 5. Highly adaptable and economical The number and arrangement of corrugated pipes can be flexibly adjusted according to actual needs, making them suitable for different geological conditions and slope heights. At the same time, this structure fully utilizes the dual functions of corrugated pipes—drainage and load-bearing—reducing the need for additional reinforcement measures and lowering construction costs.

Detailed Implementation
[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.
[0022] Please see Figures 1 to 4 This utility model provides a slope retaining wall based on corrugated pipe, including wall panel 100, front extension plate 200, rear support plate 300, anchor block 400 and corrugated pipe 500.
[0023] Specifically, the wall panel 100 is vertically arranged and has multiple through-holes 110. A front extension plate 200 is located on the front wall of the wall panel 100, near its bottom. A rear support plate 300 is located on the rear wall of the wall panel, near its bottom. Anchor blocks 400 are located on the bottom surface of the wall panel 100 for anchoring to the ground. Multiple corrugated pipes 500 are arranged along the width of the wall panel 100, closely abutting the front wall. The bottom end of each corrugated pipe 500 penetrates the front extension plate 200 and is flush with the bottom end of the anchor block 400, while the top end of each corrugated pipe 500 is flush with the top end of the wall panel 100. In practical implementation, steel corrugated pipes are preferred, as they ensure a long service life and safety during construction.
[0024] During installation, first position the anchor block 400 in the predetermined position so that the front extension plate 200 and the rear support plate 300 are supported on the ground and the wall panel 100 faces the slope side. Then anchor the anchor block 400 in the ground. Next, fix the corrugated pipe 500 along the front wall of the wall panel 100 in sequence.
[0025] The slope retaining wall is used, and the drainage holes 110, which run through the holes at the front and back of the wall, allow water accumulated on the slope to drain laterally, avoiding water pressure buildup. In addition, the drainage holes 110 and the corrugated pipes 500 work together to efficiently drain groundwater and reduce the risk of hydrostatic pressure damage to the structure.
[0026] The corrugated pipe 500 is installed close to the wall panel 100 to form a longitudinal drainage channel. Its corrugated structure enhances the interaction between the retaining wall and the soil, improving the overall stability of the retaining wall. The corrugated structure also increases the friction between the soil and the pipe, effectively preventing landslides or collapses caused by rainwater erosion or earthquakes. Furthermore, the corrugated pipe 500 possesses a certain degree of elasticity and toughness, absorbing and dispersing stress in the soil, reducing the pressure on the retaining wall, and thus extending its service life.
[0027] In practical implementation, a steel cage 600 of the same height as the corrugated pipe 500 can be embedded inside the corrugated pipe 500.
[0028] The reinforcing cage 600 provides axial tensile strength and restrains concrete expansion. The uniform height design ensures that the reinforcing cage 600 covers the entire length of the corrugated pipe 500, avoiding localized stress concentration. This structure significantly improves bending stiffness, preventing the corrugated pipe 500 from deforming under compression; the reinforcing cage 600 evenly distributes loads, extending the structure's lifespan.
[0029] In a preferred embodiment, the retaining wall of this slope also includes a limiting plate assembly 700, which includes two limiting plates 710. The two limiting plates 710 are respectively disposed in the middle and top of the front wall of the wall panel 100, and the upper end of the reinforcing cage 600 passes through the two limiting plates 710 sequentially. The limiting plates 710 can restrain the horizontal displacement of the reinforcing cage 600 and prevent it from moving around.
[0030] As another preferred embodiment, the slope retaining wall further includes a reinforcing support structure 800, which is supported between the rear wall of the wall panel 100 and the rear support plate 300. This allows the load of the wall panel 100 to be transferred to the rear support plate 300, forming a stabilizing force triangle and reducing the bending moment of the wall panel 100.
[0031] Specifically, the reinforced support structure 800 includes support blocks that are supported between the rear wall of the wall panel 100 and the rear support plate 300. The width of the support blocks on the side away from the wall panel 100 gradually decreases from bottom to top. The wider lower section resists the foundation reaction force, while the narrower upper section reduces its self-weight. Furthermore, this design conforms to the distribution law of increasing earth pressure from top to bottom, achieving efficient material utilization; reducing foundation bearing requirements; and saving construction costs.
[0032] In practical implementation, the side of the support block 810 furthest from the wall panel 100 (i.e., the rear side) can be designed as a stepped shape. The stepped design facilitates the work of maintenance personnel, and green plants can be planted on the stepped surface to beautify the environment.
[0033] Furthermore, in practice, the wall panel 100, front extension panel 200, rear support panel 300, and anchor block 400 are all precast concrete components. This reduces on-site pouring and curing time, shortens the construction period, and ensures consistent component strength by using standardized factory production, thus avoiding quality defects such as cracks.
[0034] Meanwhile, dense steel mesh or steel reinforcement bars can be embedded in the connection points between the wall panel 100 and the front extension plate 200 and the rear support plate 300. This can solve the problem of weak points in the splicing of precast components, improve the shear strength of the joints, inhibit crack propagation, and ensure long-term durability.
[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
