Description

Technical Field

[0001] The utility model relates to the technical field of wetland landscape transformation, and specifically, it is a slope structure for improving the stability of wetland slopes. Background Technique

[0002] The landscape transformation of natural wetlands refers to the process of converting natural wetlands into landscape spaces with ornamental value and ecological functions through scientific planning and design. This process not only protects and restores the wetland ecosystem but also realizes multiple ecological, social, and economic benefits, providing people with places to get close to and enjoy nature, and promoting the sustainable utilization of wetland resources.

[0003] During the process of wetland landscape transformation, the stability of the slope structure plays a crucial role. Traditional slope treatment methods often neglect ecological and landscape effects, which not only lead to the destruction of the wetland environment but also reduce its aesthetic value. However, in practical applications, the slope structures of this type of natural wetland transformation often suffer from defects such as insufficient structural stability and prone to landslides. At the same time, it is not conducive to water exchange and plant growth, resulting in high maintenance costs and great potential safety hazards. These problems not only affect the normal operation of the wetland but also may pose threats to the surrounding environment and personnel safety.

[0004] Therefore, it is particularly important to develop a wetland slope structure that can not only improve slope stability but also take into account ecological and landscape effects. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a slope structure for wetland landscaping, aiming to improve the stability of wetland slopes while taking into account ecological and landscape effects, and can be used to solve the defects in the above technical background.

[0006] The technical problem solved by the utility model is achieved by adopting the following technical solutions:

[0007] A slope structure for wetland landscaping includes a base part, an ecological slope surface, and a step edge part;

[0008] The base part includes an ecological fiber mesh surface and embedded stone strips. The ecological fiber mesh surface is padded on the bottom surface of the slope of the wetland water body; the cross-section of the embedded stone strip is a right triangle or a right trapezoid, and an embedded drill rod is formed on one of the right-angled sides of the embedded stone strip. When the embedded stone strip is assembled, the inclined surface faces outwards, and is fixed to the bottom of the mud layer structure of the slope through the embedded drill rod passing through the ecological fiber mesh surface;

[0009] The ecological slope is formed at the slope position of the wetland water body, with the upper and lower parts respectively connecting to the base part and the step edge part; the ecological slope is formed by alternately laying multiple layers of ecological fiber mesh surfaces and soil layers. The surface of each layer of ecological fiber mesh surface is compacted by a tiled gravel layer, and the soil layer is formed on the surface of the gravel layer in a tiled manner;

[0010] The step edge part includes a filling base material. The surface of the filling base material is leveled. A geotextile is paved on the leveling surface of the filling base material, and steps for walking are formed on the surface of the geotextile.

[0011] As a further limitation, the ecological fiber mesh surface is a polypropylene mesh surface or a polyester mesh surface; and during the formation stage of the ecological slope, a layer of degradable hydrophilic mesh cloth is also formed on the surface of the ecological fiber mesh surface.

[0012] As a further limitation, the ecological fiber mesh surface of the lowermost layer in the ecological slope and the ecological fiber mesh surface of the base part are of an integral structure.

[0013] As a further limitation, the corresponding angle of the inclined surface of the embedded stone strip is 0 - 15° larger than the angle of the slope of the corresponding wetland water body.

[0014] As a further limitation, a number of planting grooves are formed on the surface of the embedded stone strip along the length direction. Through holes are opened at the bottom surface of the planting grooves to facilitate water exchange and the growth of plant roots.

[0015] As a further limitation, the thickness ratio of the single-layer gravel layer to the single-layer soil layer on the surface of the single-layer ecological fiber mesh surface in the ecological slope is 1:3 - 1:5.

[0016] As a further limitation, the steps are made of one or a combination of natural stone, ecological bricks, concrete, and preservative-treated wood.

[0017] As a further limitation, fixing parts inserted into the slope of the wetland water body are formed on the lower surface of the steps to ensure the tight combination of the steps and the slope structure and improve the overall stability.

[0018] As a further limitation, the slope structure further includes a water exchange system, which is arranged between the base part and the ecological slope;

[0019] The water exchange system includes a plurality of drainage holes and drain pipes arranged along the length direction of the slope. The drainage holes are evenly distributed on the ecological fiber mesh surface of the base part, and the drain pipes penetrate through the entire slope structure to guide the water collected by the drainage holes to the outside of the slope structure.

[0020] Beneficial effects: A slope structure for wetland landscaping of the present utility model is ecologically friendly, beautiful, practical, and through modular design, the installation and maintenance of the slope structure are made more convenient, greatly shortening the construction period and reducing the project cost. The formed structure improves the structural stability of the slope under non-heavy load structures through the base part and the step edge part; at the same time, the alternating laying of the ecological fiber mesh surface and the soil layer in the ecological slope provides good conditions for plant growth, and the setting of the gravel layer helps with water body exchange. The design of the ecological slope not only facilitates soil and water conservation but also provides a good growth environment for plants.

Specific Embodiments

[0024] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0025] Refer to Figure 1 、 Figure 2 A slope structure for wetland landscaping, in this embodiment, the slope structure is used to be formed at the outer edge position of the water body of a natural wetland with an edge slope. The slope structure is formed at the position of the slope base layer 2 of the natural wetland water body, and the structure of the slope base layer 2 is improved and strengthened to assist in realizing the landscape transformation of the natural wetland water body. The slope structure from the bottom of the edge slope of the water body 1 upwards is successively the base part 3, the ecological slope 4, and the step edge part 5.

[0026] In this embodiment, the base 3 includes an ecological fiber mesh surface I12 and embedded stone strips 10. The ecological fiber mesh surface I12 is laid on the bottom surface of the slope of the wetland water body. The function of the ecological fiber mesh surface I12 is to provide a basic structural interface for the surface of the slope base layer 2 after excavation. This structural interface can prevent soil erosion when the embedded stone strips 10 are buried on the surface of the slope base layer 2 and provide support for the subsequent structure. The cross-section of the embedded stone strip 10 can be a right triangle or a right trapezoid in different embodiments. The cross-section of the embedded stone strip 10 in this embodiment is a right trapezoid as shown in Figure 1 . The inclined surface of the right trapezoid faces outwards. At the same time, two groups of embedded anchor rods 11 are formed on one right-angled side of the right trapezoid of the embedded stone strip 10. The embedded stone strip 10 passes through the ecological fiber mesh surface I12 through the embedded anchor rods 11 and is inserted and fixed at the bottom of the mud layer structure of the slope base layer 2.

[0027] The corresponding angle of the inclined surface of the embedded stone strip 10 is 0-15° larger than the slope angle of the slope base layer 2 of the natural slope formed in the corresponding wetland water body, so as to ensure the stability of the structure of the base 3 itself and provide a stable deposition slope for the surface soil layer 15 of the ecological slope 4.

[0028] As an alternative technical solution of this embodiment, the length of the embedded stone strip 10 can be customized according to the size of the slope base layer 2 of the actual water body 1, and multiple embedded stone strips 10 are spliced in the length direction; in addition, planting grooves can be formed on the surface of the embedded stone strip 10 along the length direction, and through holes are opened at the bottom surfaces of these planting grooves to facilitate water exchange and the growth of plant roots, so as to facilitate the planting of emergent plants and floating-leaved plants in the planting grooves.

[0029] The ecological slope 4 is formed at the slope position of the wetland water body, and the upper and lower parts respectively connect the base 3 and the step edge part 5. The ecological slope 4 is formed by laminating multiple combined structural units. In this embodiment, the number of laminated layers of the combined structural units of the ecological slope 4 is three. Each layer of the combined structural unit includes an ecological fiber mesh surface II 13, a gravel layer 14, and a soil layer 15; the innermost combined structural unit is directly laid flat on the surface of the slope base layer 2 of the inclined plane formed after excavation with the ecological fiber mesh surface II 13. The surface of the ecological fiber mesh surface II 13 is compacted with the laid gravel layer 14, and the soil layer 15 is formed by backfilling the bottom mud reserved after the excavation of the slope base layer 2 after sterilization, disinfection, and drying, and is formed on the surface of the gravel layer 14 in a flat-laying manner.

[0030] In this embodiment, the ecological fiber mesh surface II 13 in the innermost layer combined structural unit and the ecological fiber mesh surface I 12 of the base 3 are of an integral structure, mainly to improve the structural integrity and stability, and reduce the forming difficulty and structural cost. At the same time, the thickness ratio of the single-layer gravel layer 14 to the single-layer soil layer 15 on the surface of the single-layer ecological fiber mesh surface II 13 in the ecological slope 4 is 1:3 to 1:5. This thickness structure can ensure good soil and water conservation and plant growth conditions, and at the same time will not inhibit the growth of tall emergent plants with developed roots at the position of the ecological slope 4, ensuring the openness of the waterside landscape view and the convenience of ecological maintenance.

[0031] In this embodiment, both the ecological fiber mesh surface I 12 and the ecological fiber mesh surface II 13 are made of polypropylene materials, having good tensile strength and durability, and can adapt to various climate conditions and soil environments. The weaving structure of the ecological fiber mesh surface I 12 and the ecological fiber mesh surface II 13 is designed as a hexagon to ensure a high porosity, which is conducive to water body exchange and the growth of plant roots. In addition, during the forming stage of the ecological slope 4, a layer of degradable hydrophilic mesh cloth is formed on the surface of the corresponding ecological fiber mesh surface II 13. This degradable hydrophilic mesh cloth itself can provide additional structural support, play a role in fixing the soil in the initial stage of plant growth, and prevent soil erosion. At the same time, this degradable hydrophilic mesh cloth can be degraded by the soil layer 15 and the microorganisms in the water body 1 in the microbial environment of the water body 1. As the plant roots gradually develop, this mesh cloth will gradually degrade, not only will it not affect the plant growth, but also can provide certain nutrients for plant growth.

[0032] In another embodiment, in order to ensure the stability of the overall structure of the ecological slope 4, a plurality of strengthening vertical ribs can also be arranged at intervals in the length direction of the ecological slope 4 (the direction perpendicular to the connection line between the base 3 and the step edge part 5). The corresponding strengthening vertical ribs are precast cement structures, and their upper and lower parts respectively abut against the base 3 and the step edge part 5.

[0033] The step edge part 5 is located above the ecological slope 4, and its main function is to provide a transition area for the slope structure to prevent soil erosion and provide a safe walking and viewing platform for people. In this embodiment, the step edge part 5 is composed of a step 6 and a filling base material 7. The step 6 is formed on the surface of the leveled filling base material 7. At the same time, a geotextile 8 is also arranged between the step 6 and the filling base material 7. The geotextile 8 is usually selected as a high-strength geotextile to ensure the normal exchange between the water body and the soil, and at the same time prevent fine soil particles from flowing away with the water to form a hollow phenomenon in the interface layer between the step 6 and the filling base material 7, thus affecting the structural strength of the slope structure.

[0034] In different embodiments, the step 6 can be made of one of natural stone, ecological brick, concrete, antiseptic wood or a combination thereof, and its outer side can bear the road surface structure 9 or the structural trestle in the manner shown in the figure. The filling substrate 7 is a building filling material, such as gravel, pebbles, crushed rocks, etc., which is used to fill the surface of the slope base 2 at the outer edge of the water body 1 to ensure the structural stability of the step edge 5.

[0035] In another embodiment, a fixing piece inserted into the structure of the slope base 2 can be formed on the lower surface of the step 6 to ensure the close combination of the step edge 5 and the slope base 2, thereby improving the overall stability. In addition, the step 6 not only has a practical function, but also has an aesthetic effect. The material surface of the step 6 can be artistically processed, such as carving, painting, etc., to coordinate with the wetland landscape. In addition, the height and width of the step 6 can be adjusted according to actual needs to meet the needs of different groups of people.

[0036] In addition, in order to ensure water exchange and ecological balance of the slope structure, the slope structure also includes a water exchange system. The water exchange system is arranged between the base 3 and the ecological slope 4, and includes a plurality of drainage holes and drainage pipes arranged along the length direction of the slope. The drainage holes are evenly distributed on the ecological fiber mesh surface of the base, and the drainage pipe runs through the entire slope structure to guide the water collected by the drainage holes to the outside of the slope structure.

[0037] Through the above design, the slope structure of the utility model not only improves the stability of the slope, but also takes into account the ecological and landscape effects, providing an effective solution for the landscaping transformation of the wetland.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
