Description

Technical Field

[0001] This invention relates to the technical field of slope greening, and more specifically, to a greening structure and method for slope protection. Background Technology

[0002] In the field of slope protection and ecological restoration, slope greening structures are effective soil stabilization and environmental restoration measures, widely used in exposed slopes or rocky areas such as highways, mining areas, and river channels. For example, CN109797758B discloses a greening structure for exposed rock surfaces, which consists of anchor piles, retaining walls, protective netting, and a substrate system to form greening units that support plant growth and provide slope protection. This technology achieves a certain degree of vegetation cover on slopes, especially by adding nutrients and water-retaining materials to the substrate layer, helping plants grow in relatively barren or exposed rock environments.

[0003] The technology involves the combined installation of anchor piles, retaining walls, protective nets, and multi-layer matrix systems. Each component needs to be fixed and connected separately on the slope, making the overall installation process complicated. Especially on irregular slopes, a lot of on-site adjustments are required, which increases the installation difficulty and construction time. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a greening structure and method for slope protection that is easy to install, structurally stable and highly erosion resistant.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A greening structure for slope protection includes several greening units set on the construction surface of the slope protection. Each greening unit is composed of several anchor piles and a pipe assembly that connects the anchor piles to form a closed area.

[0007] The anchor pile has a rod at the top, and the tube has rings at both ends for fitting onto the rod. A locking nut for pressing the rings is threaded onto the rod. Several positioning holes are provided on the tube.

[0008] The anchor pile has several connecting holes that penetrate its body on its outer peripheral wall.

[0009] The invention is further configured such that: a protective net is installed in the greening unit in an upper, middle and lower relationship, and the protective net is provided with hanging parts.

[0010] The present invention is further configured such that a plurality of insert rods connected to the construction surface are inserted into the positioning hole.

[0011] The invention is further configured such that steel wire ropes are connected to connecting holes at the same horizontal level on each anchor pile.

[0012] The wire rope has threaded portions at both ends for nut connection;

[0013] The hanger has holes for the wire rope to pass through so that the protective net can be placed on the wire rope.

[0014] The present invention is further configured such that: a bottom layer of substrate is laid on the lower protective net within the greening unit, a middle protective net is placed on the bottom substrate, the middle layer of substrate is laid on the middle protective net, an upper protective net is placed on the middle substrate, and a surface substrate is laid on the upper protective net.

[0015] The invention is further configured such that: a vegetation mat is laid on the surface substrate, and a fine fiber net is added on the vegetation mat, which is fixed to a steel wire rope.

[0016] The invention is further configured such that the positioning hole is opened at an angle so that the insertion rod can further compress the bottom matrix, the middle matrix and the surface matrix when inserted along the positioning hole.

[0017] A greening method for a slope protection greening structure includes the following steps:

[0018] Step 1: Installation of anchor piles and pipe body

[0019] Anchor piles are arranged on the slope protection construction surface according to the designed greening units, and the anchor piles are fixed on the slope surface.

[0020] The two ends of the pipe are fitted onto the rod of the anchor pile, and the loops are fixed to the rod by locking nuts to form a closed greening unit area.

[0021] Step 2: Layered installation of the protective netting and matrix filling

[0022] Bottom protective net and substrate filling: Install the bottom protective net at the bottom of the greening unit and fix the protective net to the steel wire rope at the first height with hangers. Then, evenly lay the bottom substrate on the bottom protective net and gently compact it to form a stable base layer.

[0023] Middle layer protective netting and matrix filling: A middle protective netting is laid on top of the bottom matrix, and the protective netting is fixed to the steel wire rope at the second height by hanging devices;

[0024] Next, the middle layer of matrix is ​​evenly filled into the middle protective netting and properly compacted to ensure close contact with the bottom layer of matrix;

[0025] Upper protective net and substrate filling: Install a protective net above the middle substrate and fix the protective net to the steel wire rope at the third height with hangers. Then lay the top substrate on the upper protective net, so that it is evenly covered and moderately compacted to provide an ideal growth environment for vegetation.

[0026] Step 3: Covering with vegetation mat and fiber mesh

[0027] A vegetation mat is laid on the surface substrate, and a fine fiber net is added on top of the vegetation mat. The fiber net is then fixed to a steel wire rope at the third height.

[0028] Step 4: Compacting the insertion rod

[0029] Insert the insert along the slanted positioning hole, allowing the insert to penetrate and compress the bottom substrate, middle substrate, and top substrate.

[0030] Compared with the shortcomings of the prior art, the beneficial effects of the present invention are as follows:

[0031] The modular combination of anchor piles, pipes, wire ropes and protective nets enables rapid installation and efficient on-site adjustment of the structure, allowing for large-area operations.

[0032] This invention connects the anchor piles in their connection holes with horizontal steel wire ropes and provides layered support to the substrate using multi-layered protective netting to prevent substrate slippage. Simultaneously, by inserting oblique rods into the positioning holes, further compaction is applied to each substrate layer, ensuring its stability and preventing loosening.

[0035] Anchor pile 1, pipe body 2, pole 11, positioning hole 20, connecting hole 10, ring 21, upper protective net 101, middle protective net 102, lower protective net 103, insertion pole 3, steel wire rope 4. Detailed Implementation

[0036] Reference Figures 1 to 2 The embodiments of the present invention will be further described below.

[0037] In this specific embodiment, several greening units are arranged on the construction surface according to the construction area of ​​the slope protection. These greening units together form a complete slope protection greening structure to cover the entire slope area and achieve a comprehensive slope greening effect.

[0038] Each greening unit consists of multiple anchor piles 1 and pipe bodies 2 connecting each anchor pile 1. The anchor piles 1 and pipe bodies 2 enclose a closed area, which can both restrict the movement of the substrate and provide a fixed growth space for the plant roots.

[0039] A rod 11 is provided at the top of the anchor pile 1, and the two ends of the tube body 2 are equipped with ring parts 21. The ring parts 21 are fitted onto the rod 11, and the ring parts 21 are firmly fixed by the threaded locking nuts.

[0040] Multiple positioning holes 20 are made on the pipe body 2, arranged at an angle. During installation, the insertion rod 3 is inserted along the positioning holes 20 and penetrates deep into the slope, thereby firmly connecting the pipe body 2 to the slope. The design of the positioning holes 20 and the insertion rod 3 not only enhances the stability of the structure, but also provides the function of further compacting the substrate.

[0041] Several connecting holes 10 are made on the outer peripheral wall of the anchor pile 1, which penetrate the body. The connecting holes 10 are used to fix the wire rope 4 and the protective net, providing multi-layer support. The wire rope 4 is connected to the anchor pile 1 through the threaded part and the nut to form a transverse support network. This design effectively resists slope slippage and external impact, ensuring the overall stability of the structure.

[0042] Within each greening unit, protective nets are installed at three different heights: upper, middle, and lower. These protective nets are fixed to steel wire ropes 4 at different heights by hangers. The layered installation of the protective nets provides independent support for different substrate layers, enhancing the erosion resistance of the substrate system.

[0043] The hanging brackets on the protective netting have holes for threading through the steel wire rope 4. Each layer of the protective netting is securely fixed to the steel wire rope 4 by the hanging brackets, ensuring that it is not easily loosened on the slope. The cooperation between the protective netting and the steel wire rope 4 provides sufficient support for each layer of substrate, preventing slippage or deformation between substrate layers.

[0044] A bottom substrate is laid on the lower protective netting 103. The bottom substrate is mainly used to stabilize the overall structure, provide good drainage and compressive strength, and form a solid foundation support with the bottom protective netting to ensure the growth of the upper substrate and plant roots.

[0045] Install a middle layer protective net 102 above the bottom substrate and fill it with middle layer substrate. The middle layer substrate provides suitable nutrients and water for the meso-rooted plants, plays a role in layered support, and prevents the plant roots from concentrating in the surface substrate.

[0046] An upper protective net 101 is installed above the middle substrate, and a top substrate is filled on top of it. The top substrate provides a nutrient layer suitable for the growth of shallow-rooted plants. The upper protective net 101 supports the top substrate, prevents it from being washed away by rainwater, and provides long-lasting coverage and protection for the vegetation.

[0047] A vegetation mat and a fine fiber net are laid on top of the surface substrate. The combination of the vegetation mat and the fiber net provides additional protection for the substrate layer, preventing erosion from rain and wind. The vegetation mat, covering the surface substrate, effectively maintains surface moisture, helps plant seeds germinate quickly, and ensures a high survival rate. The fiber net, covering the vegetation mat and secured to steel wire rope 4, protects the surface substrate through its tight structure, preventing erosion caused by wind and rain, and ensuring the integrity of the slope structure and the stability of vegetation growth.

[0048] The angled positioning hole 20 facilitates the insertion of the rod 3 at a predetermined angle. After the rod 3 penetrates the bottom, middle and top matrix layers, it applies vertical pressure to each matrix layer, further enhancing the stability of the matrix and preventing interlayer slippage. At the same time, the compaction effect of the rod 3 makes the matrix layer more compact, improving the overall erosion resistance of the structure.

[0049] A greening method for a slope protection greening structure includes the following steps:

[0050] Anchor piles 1 are arranged on the slope protection construction surface according to the designed greening units. By fixing the anchor piles 1 on the slope surface, the two ends of the pipe body 2 are fitted onto the rod part 11 of the anchor pile 1. The ring part 21 is fixed to the rod part 11 by tightening the locking nut, thus forming a closed greening unit area.

[0051] Install a lower protective net 103 at the bottom of the greening unit, and fix the protective net to the steel wire rope 4 at the first height by means of hanging brackets. Then, evenly lay the bottom substrate on the lower protective net and gently compact it to form a stable base layer.

[0052] Middle layer protective netting 102 and matrix filling: The middle protective netting is laid on top of the bottom matrix, and the protective netting is fixed to the steel wire rope 4 at the second height by the hangers;

[0053] Next, the middle layer of matrix is ​​evenly filled into the middle protective netting and properly compacted to ensure close contact with the bottom layer of matrix;

[0054] Upper protective net 101 and substrate filling: Install a protective net above the middle substrate and fix the protective net to the steel wire rope 4 at the third height with hangers. Then lay the surface substrate on the upper protective net to cover it evenly and compact it appropriately to provide an ideal growth environment for vegetation.

[0055] A vegetation mat is laid on the surface substrate, and a fine fiber net is added on top of the vegetation mat. The fiber net is then fixed to the steel wire rope 4 at the third height.

[0056] Insert the rod 3 along the inclined positioning hole 20, allowing it to penetrate and compress the bottom, middle, and top substrates. This compaction design of the positioning hole 20 and the rod 3 ensures a tight bond between each substrate layer, enhancing its erosion resistance and effectively preventing slippage or delamination due to external forces. The compacted substrate layer exhibits stronger erosion and slip resistance, ensuring the stability and durability of the slope greening structure under harsh conditions.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
