Plant maintenance structure for a slope ecological restoration system

Abstract

This utility model discloses a plant maintenance structure for a slope ecological restoration system, comprising a double-layered maintenance container. The maintenance container includes an inner shell with an open top and an outer shell. The outer shell has a trapezoidal cross-section, while the inner shell has a U-shaped or arc-shaped cross-section with a downward-concave center. The planting cavity between the inner and outer shells is filled with planting soil and bagged humus, with the humus located below the bottom wall of the inner shell. This utility model makes the planting soil approximately U-shaped, with humus in the bottom center. Plant roots grow and extend into the planting soil at the bottom of the inner shell, and the plant roots on both sides extend to the opposite sides and intersect, which can promote plant root growth and improve soil and water conservation capacity. In addition, the maintenance container can be directly removed later to plant in the excavated trench to form a drainage ditch, significantly reducing the hard surface area of ​​the project and making the drainage ditch integrated with the surrounding environment.

Description

Technical Field

[0001] This utility model relates to soil and water conservation in ecological restoration, and in particular to a plant maintenance structure for slope ecological restoration systems. Background Technology

[0002] Traditional drainage ditches are generally constructed of masonry or concrete. In areas with relatively low rainfall, such as semi-arid regions, these ditches are not conducive to the in-situ infiltration of rainwater and the improvement of the ecological environment. Furthermore, the large amount of hard-surface construction is not conducive to energy conservation and carbon reduction. To address this, integrated ecological system concrete drainage ditches have emerged in existing projects. Although these ditches have water permeability, they still suffer from the problem of numerous hard-surface constructions and easy clogging of pores. Summary of the Invention

[0003] In view of this, this utility model proposes a plant maintenance structure for slope ecological restoration system, which is conducive to the growth of plant roots and allows the plant roots on both sides to extend and intersect to the opposite side. During the later planting, the maintenance container can be removed and the plant can be planted in the soil ditch to form a plant drainage ditch. On the one hand, the drainage ditch can be integrated with the surrounding environment, and on the other hand, it can promote the in-situ infiltration of rainwater.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The plant maintenance structure for slope ecological restoration system described in this utility model includes a double-layered maintenance container. The maintenance container includes an inner shell with an opening at the top and an outer shell. The outer shell has a trapezoidal cross-section, and the inner shell has a U-shaped or arc-shaped cross-section with a downward concave center. The inner shell is located inside the outer shell. The planting cavity between the inner and outer shells is filled with planting soil and bagged humus, and the humus is located below the bottom wall of the inner shell.

[0006] The beneficial effects are as follows: The maintenance container of this invention creates an approximately U-shaped structure for the planting soil within the planting cavity. The bottom center of the planting soil contains humus. Trees or shrubs are planted on both sides of the container, and their roots grow and extend into the planting soil at the bottom of the inner shell. The roots on both sides extend and intertwine, promoting root growth and improving soil and water conservation. Furthermore, during later planting, the maintenance container can be removed, and the plant can be planted directly in a drainage ditch. This allows the drainage ditch to blend seamlessly with the surrounding environment and significantly reduces the hard surface area of ​​the slope.

[0007] More preferably, the inner shell has evenly distributed prisms on a pair of sidewalls, with the prisms arranged in layers from top to bottom along the sidewalls of the inner shell, the layer height being 0.1m to 0.2m. Holes are present between the upper and lower layers of prisms, resulting in a row of holes on each sidewall of the inner shell. This invention's inner shell, with its layered prism design, promotes plant root growth, thereby forming a U-shaped root system.

[0008] Preferably, the height of the outer shell is 0.3m to 0.6m, the depth of the inner shell is 0.2m to 0.4m, and the width difference between the upper opening of the outer shell and the upper opening of the inner shell is 0.1m to 0.2m.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] The maintenance container of this utility model makes the planting soil inside the planting cavity approximately U-shaped. The bottom and middle of the planting soil contains humus. Trees or shrubs are planted on the left and right sides of the maintenance container. The plant roots grow and extend into the planting soil at the bottom of the inner shell. The plant roots on both sides extend to the opposite side and intersect. When planting later, the maintenance container can be removed and the plant planted in the soil ditch to form a plant drainage ditch. This not only makes the drainage ditch blend into the surrounding environment, but also promotes the infiltration of rainwater on the spot. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 As shown, the plant root reinforcement and maintenance structure used in the slope ecological restoration system includes a double-layered maintenance container. The maintenance container comprises an outer shell 1 with an open top and an inner shell 2. Both outer shell 1 and inner shell 2 are open-top plastic boxes (preferably made of PP material). The cross-section of the inner shell 2 is a trapezoidal structure consistent with the cross-sectional structure of the drainage ditch, facilitating subsequent drainage ditch construction. The cross-sectional structure of the outer shell 1 is an arc-shaped structure with a downward concave center, i.e., the outer shell 1 has an arc-shaped wall (e.g., ...). Figure 1 As shown), the outer shell 1 is located inside the inner shell 2 to form a planting cavity with openings on both sides. The planting cavity is filled with planting soil and bagged humus, and the humus is placed below the bottom wall of the outer shell 1.

[0019] In actual maintenance, the inner shell 2 has evenly distributed prisms 3 on its pair of sidewalls. The prisms 3 are arranged in layers along the sidewalls of the outer shell 1 from top to bottom. There are evenly distributed holes 4 between the upper and lower prisms. See details. Figure 2 The inner shell 2 has an embossed design on its inner wall with upper and lower prismatic layers, which promotes root extension and helps the plant form a U-shaped root system. In practical maintenance, the height of the inner shell 2 is preferably 0.2m–0.4m, and the height of the outer shell 1 is preferably 0.3m–0.6m; the width difference between the upper opening of the outer shell and the upper opening of the inner shell is preferably 0.1m–0.2m to facilitate planting and meet the plant's maintenance needs.

[0020] Ecological restoration is typically required for areas surrounding disturbed sites and above slopes. Before construction, an ecological survey of the project area's vegetation is conducted to determine the necessary tree or shrub species for the ecological drainage ditch based on the existing vegetation community types. Once determined, the root system reinforcement and maintenance structure of this invention is used to maintain the root systems of the selected tree or shrub seedlings before construction of the drainage ditch. This invention uses Platycladus orientalis (a tree) as an example to illustrate its maintenance process:

[0021] First, select a suitable size maintenance container. The top width of the outer shell 1 is 0.8m, the bottom width is 0.6m, and the height is 0.35m; the top width of the inner shell 2 is 0.5m and the depth is 0.2m. To facilitate subsequent transplanting, the length of the outer shell 1 and the inner shell 2 can be controlled within 5m to reduce the difficulty of removing the shell and planting the Chinese arborvitae after maintenance.

[0022] Next, fill the outer shell 1 with planting soil F1 and place the ecological bagged humus soil F2 at the corresponding position on the bottom wall of the inner shell 2; place the inner shell 2 on top of the humus soil F2, insert the arborvitae F3 at intervals in the gaps on both sides of the outer shell 1 and the inner shell 2, and continue to fill the gaps on both sides of the outer shell 1 and the inner shell 2 with planting soil, and water and maintain it regularly (maintenance time ≥ 1 year, or it can be 2 years) so that the roots of the arborvitae F3 fill the entire planting cavity.

[0023] Because the middle part of the planting soil contains humus soil F2, and the roots of the Chinese arborvitae F3 are fertile, the roots of the Chinese arborvitae F3 planted on both sides grow towards the humus soil F2, and even extend to the opposite side and cross together, forming a U-shaped plant root system. The root system is well-developed, which improves the survival rate and soil and water conservation capacity.

[0024] During construction, drainage trenches can be excavated at designated locations. The cured cypress (with the outer shell 1 removed) along with the planting soil is planted in the excavated trenches. The inner shell 2 is then removed, and clay is applied to the inner wall of the planting soil to form a plant drainage ditch. In this invention, the combination of the inner and outer shells helps to stabilize the root system. Even after long-term root growth, which no longer requires stabilization, the root system maintains a certain shape, thus serving to drain water and stabilize slopes. Furthermore, it allows the planting soil to integrate with the surrounding soil, significantly reducing the hard surface area of ​​the project and lowering the construction cost of the drainage ditch, resulting in an ecological drainage ditch. See details below. Figure 3-4 .

[0025] Finally, it should be emphasized that the above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
