Description

Technical Field

[0001] The present invention relates to the field of ecological restoration of bank slopes in a drawdown zone, and in particular to a repair and treatment structure for wave erosion sites and an ecological restoration method thereof. Background Art

[0002] The rise and fall of water levels in the Three Gorges Reservoir creates a large number of drawdown zones. The ecological fragility of these zones leads to ecological problems that will impact the safety of the reservoir. Erosion of these drawdown zones is a natural process driven by the combined effects of multiple forces, including fluctuating water levels, wave erosion, and rainfall runoff. Waves, as a significant external force, have a significant impact on the erosion of these zones. The long-term erosion of reservoir banks by waves within the reservoir creates erosion zones, which can lead to bank collapse. Ecologically, the new environment of periodic flooding and drought stress in the drawdown zone has led to the mass elimination of native plants, resulting in a continuous decline in species diversity, gradual structural degradation, and a continuous decline in soil and water conservation and ecological regulation capabilities.

[0003] Therefore, to maintain the safety of the reservoir, in addition to repairing and reinforcing the eroded areas, ecological restoration is also necessary. While traditional materials like blocks and sand and gravel offer strong resistance to wave erosion, they fail to restore or protect the ecosystem. Instead, they hinder energy exchange between soil and water, damaging the ecosystem. While using plant bags to repair erosion pits is effective, they are easily damaged by sharp objects and lack the long-term protective effect on the banks. Therefore, a method that can simultaneously mitigate wave erosion and maintain ecological resilience is needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a repair and treatment structure for wave erosion sites and an ecological restoration method thereof, which can be used for ecological repair projects of bank erosion sites such as lakes and reservoirs.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a repair and treatment structure for wave erosion areas, including a support frame system installed in the erosion pit, a mixed matrix filled in the support frame system and in the gap between the erosion pit, and a metal mesh is provided on the outer surface of the support frame system and inside the support frame system.

[0006] In a preferred embodiment, a plurality of implantation nails are further included, and the implantation nails are implanted in the mixed matrix.

[0007] In a preferred solution, the planting nail includes a placement tube, in which seeds are arranged, and the placement tube is made of degradable plastic.

[0008] In a preferred solution, a barb is provided on the outside of the placement tube.

[0009] In a preferred solution, the support frame system includes vertical poles, horizontal poles and diagonal poles, and the vertical poles and horizontal poles are interconnected to form a frame body adapted to the erosion pit.

[0010] In a preferred solution, the vertical poles, longitudinal poles and transverse poles are connected via an adapter, which includes a connecting base with a connecting protrusion, and the ends of the vertical poles, longitudinal poles and transverse poles are all provided with connecting grooves that cooperate with the connecting protrusions.

[0011] In a preferred embodiment, the mixed matrix consists of porous particles and planting soil, and the mass ratio of the porous particles to the planting soil is 5:1 to 3:1.

[0012] In a preferred embodiment, the porous particles are hydraulic inorganic gel particles.

[0013] The present invention also provides an ecological restoration method for wave erosion sites, comprising the following steps:

[0014] Step 1: Clean the erosion pit and measure its dimensions, and make vertical poles, horizontal poles and diagonal poles of the support frame system of corresponding dimensions according to the measured dimensions;

[0015] Step 2: Splice the support frame system in the erosion pit, and splice and fix the support frame system in the erosion pit;

[0016] Step 3: Fix the metal mesh on the contact surface between the support frame system and the erosion pit, and fill and compact the gap between the metal mesh and the erosion pit with the mixed matrix. The installation of the metal mesh and the filling of the mixed matrix are performed alternately.

[0017] Step 4: Fill and compact the internal space enclosed by the support frame system and the metal mesh with the mixed matrix;

[0018] Step 5: Encapsulate and fix the unencapsulated surface of the support frame system with a metal mesh;

[0019] Step 6: Drive the implant nails into the surface of the mixed matrix encapsulated and fixed by the metal mesh.

[0020] The present invention provides a repair and treatment structure for wave-eroded areas and an ecological restoration method thereof. The support frame system provides a skeleton support for the erosion pit, effectively preventing the wave-eroded area of ​​the bank slope from collapsing due to gravity. The support frame system and the erosion pit are filled with a mixed matrix. Because of its wave-breaking and erosion-reducing properties, it effectively hinders the impact and damage of waves on the slope, and can provide a suitable growth environment for plants, thereby performing ecological repairs on the bank slope ecology. The treatment structure and ecological restoration method have simple construction technology, low cost, and a short process, and have a wide range of application value. Preferably, the planting nails are inserted into the mixed matrix, which is conducive to the planting of seeds, and the planting range and depth are controllable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] like Figures 1 to 4 The figure shows a structure for repairing wave-eroded areas. It includes a support frame system 1 installed within the erosion pit. A mixed matrix 2 is filled within the support frame system 1 and in the gaps between the support frame system 1 and the erosion pit. Metal mesh 3 is installed on the outer surface of the support frame system 1 and between the support frame system 1 and the outside of the erosion pit. In a specific implementation, the metal mesh 3 within the support frame system 1 is divided into multiple filling units. This structure effectively prevents gravity collapse in the erosion pit, resists wave erosion on the bank, provides a suitable environment for plant growth, and enhances wave erosion reduction performance.

[0030] In the preferred embodiment, Figure 5 As shown, the apparatus also includes several planting spikes 4, which are inserted into the mixed matrix 2. These spikes 4 include a hollow tube 401, 3-5 cm in length and 4-6 mm in outer diameter. Tube 401 is made of biodegradable plastic. Seeds 402, 50-70 of which are suitable for the surviving Bermudagrass, are placed inside tube 401. Barbs 403 are located on the outside of tube 401 to prevent the spikes 4 from being dislodged due to external forces after insertion into the mixed matrix 2, providing a stable environment for the Bermudagrass seeds to grow and develop.

[0031] After the planting nail 4 is inserted into the mixed matrix 2, as the placement tube 401 degrades, the seeds 402 grow in the mixed matrix, which is beneficial for planting the seeds.

[0032] In a preferred solution, the support frame system 1 includes vertical rods 101, longitudinal rods 102, transverse rods 103 and diagonal rods 104. The vertical rods 101, longitudinal rods 102 and transverse rods 103 are interconnected to form a frame body adapted to the erosion pit.

[0033] The vertical rod 101, the longitudinal rod 102 and the transverse rod 103 are connected by an adapter, which includes a connecting base 105, on which a connecting protrusion 106 is provided. The ends of the vertical rod 101, the longitudinal rod 102 and the transverse rod 103 are all provided with a connecting groove 107 that cooperates with the connecting protrusion 106.

[0034] The members of the support frame system 1 are constructed of lightweight continuous fiber-reinforced thermoplastic material. After construction, they will not significantly impact the slope's stability by inducing secondary loading. The cross-section can be square or circular, with a side length or diameter of 10-15 cm. The lengths of the vertical, longitudinal, transverse, and diagonal members 101, 102, 103, and 104 members of the support frame system 1 are determined based on on-site measurements of the erosion pit. After connecting the vertical, longitudinal, and transverse members 101, 102, and 103 members to the adapter 105, they are heat-fixed to achieve optimal connection stability. The diagonal member 104 can be connected to the other members using hot-melt connections.

[0035] In a preferred embodiment, the metal mesh 3 is a stainless steel wire mesh with a pore size of 5-7 mm and a wire diameter of 1-3 mm. The metal mesh 3 is secured to the support frame system 1 via spikes. The metal mesh 3 encapsulates and secures the mixed matrix 2, preventing it from collapsing and further enhancing its resistance to wave erosion.

[0036] In a preferred embodiment, the mixed matrix 2 is composed of porous particles and planting soil, with the mass ratio of porous particles to planting soil being 5:1 to 3:1. In this embodiment, the mass ratio of porous particles to planting soil is 5:1. After the mixed matrix 2 is filled and the surface plant growth is complete, it can effectively reduce wave erosion on the slope and play an ecological restoration role.

[0037] The porous particles can be ceramsite.

[0038] In this embodiment, the porous particles are hydraulically hardening inorganic gel particles, which are regular hexahedrons with a large number of pores inside, have a side length of 1 to 2 cm, and have strong anti-scouring ability. The preparation method is as follows: a water-soluble solidifiable material is filled into a polygonal component with a higher melting point. The solidifiable material can be potassium aluminum sulfate dodecahydrate. After the solidifiable material solidifies, a sealing treatment is performed to ensure that the component will not be squeezed and deformed by external forces. The treated material is evenly filled into a container with a porous partition compartment. Powdered hydraulic inorganic gelling material is added to the container. The hydraulic inorganic gelling material can be phosphate cement. After the inorganic gelling material in the container solidifies, the mixture is removed and cut into small particles. The particles are then immersed in water to dissolve the potassium aluminum sulfate dodecahydrate to form porous particles.

[0039] An ecological restoration method for wave erosion sites, comprising the following steps:

[0040] Step 1: Clean the eroded pit and measure its size, and make the vertical poles 101, longitudinal poles 102, horizontal poles 103 and diagonal poles 104 of the support frame system 1 of corresponding sizes according to the measured sizes.

[0041] Step 2: Splice the support frame system 1 in the erosion pit, and splice and fix the rods of the support frame system 1 in the erosion pit.

[0042] Step 3: Fix the metal mesh 3 to the contact surface of the support frame system 1 and the etched pit. Fill and compact the gap between the metal mesh 3 and the etched pit with the mixed matrix 2. Alternate between installing the metal mesh 3 and filling the mixed matrix 2. The metal mesh 3 blocks and supports the mixed matrix 2.

[0043] Step 4: Fill and compact the interior space enclosed by the support frame system 1 and the metal mesh 3 with the mixed matrix 2, completing the entire erosion pit. In practice, depending on the size of the erosion pit, the support frame system 1 is separated by metal mesh 3. The support frame system 1 and metal mesh 3 are used to construct a unit structure to prevent a rupture in a portion of the metal mesh 3, which would cause the mixed matrix to be lost from the entire structure and render the ecological restoration function ineffective.

[0044] Step 5: The outer unpackaged surface of the support frame system 1 is packaged and fixed with the metal mesh 3, as shown in FIG. Figure 6 shown.

[0045] Step 6: Drive the implant nails 4 into the surface of the mixed matrix 2 encapsulated and fixed by the metal mesh 3.
