Description

Technical Field

[0001] This invention belongs to the field of ecological bank protection technology and relates to an ecological bank protection module that adapts to water flow pressure. Background Technology

[0002] While existing ecological bank protection technologies employ various structures and methods to protect riverbanks from water erosion, several problems remain. For instance, traditional bank protection structures lack effective adaptability when facing varying intensities of water flow, making them prone to structural damage. Although some bank protection structures utilize flexible materials, they still struggle to guarantee slope stability and the sustainability of ecological functions when dealing with complex changes in water flow pressure.

[0003] Therefore, there is a need for an ecological revetment module that can adapt to water flow pressure, has good buffering performance, and can ensure slope stability. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an adaptive water flow pressure ecological revetment module with a hydraulic buffer layer. This module combines flexible materials with prestressed anchor technology, enabling it to disperse and absorb energy under water flow impact through the deformation of the honeycomb structure and the liquid flow of the hydraulic layer, thereby reducing structural damage. Furthermore, the prestress is dynamically adjusted through pressure sensors and hydraulic rods built into the anchor system to ensure slope stability.

[0005] Specifically, it includes a flexible shell, a variable support structure, hydraulic cushioning filling material, an ecological matrix filling material, and a vegetation layer; The variable support structures are interconnected to form an integral frame structure, which is installed in a flexible shell. The flexible shell contains, from top to bottom, a vegetation layer, an ecological matrix filling material, and a hydraulic buffer filling material. The hydraulic buffer filling material is filled inside the variable support structure to obtain the revetment module. The revetment module is installed on the embankment through a prestressed anchor system.

[0006] Preferably, the flexible shell is made of a high-strength, corrosion-resistant flexible material with good elasticity and wear resistance, and can withstand a certain degree of water flow impact without breaking. Most preferably, the flexible shell is made of polyurethane or polyurea elastomer material.

[0007] Preferably, the variable support structure is made of a lightweight, high-strength material and is in the shape of a regular polygon. Most preferably, the variable support structure is made of geogrid or fiberglass and is in the shape of a regular hexagon.

[0008] Preferably, the hydraulic buffer filling material is a high-viscosity, low-flow liquid material, preferably a plant fiber-starch mixture. The hydraulic buffer layer is sealed inside the honeycomb structure. When water flows and impacts the revetment module, the honeycomb structure deforms, and the liquid in the hydraulic buffer layer flows accordingly. The viscosity and flow resistance of the liquid absorb and disperse the kinetic energy of the water flow.

[0009] Most preferably, the plant fiber-starch mixture comprises plant fiber, starch, and water in a mass ratio of 1:(0.3-0.5):(6.5-15).

[0010] Preferably, the ecological matrix filling material is a biocompatible adhesive material, preferably a bentonite-biochar composite material. This ecological cementitious material not only fills the gaps between the honeycomb structure and the hydraulic buffer layer, but also provides a substrate for vegetation growth and, to some extent, enhances the overall strength of the revetment module.

[0011] Preferably, the mass ratio of bentonite to biochar in the bentonite-biochar composite material is 1:(0.5-1.5). In arid regions, a mass ratio of 1:(0.5-0.8) results in a higher proportion of bentonite, leading to better water absorption and expansion, and stronger water retention. In polluted water areas, a mass ratio of 1:(1.0-1.5) results in a higher proportion of biochar, enhancing the adsorption capacity for nitrogen, phosphorus, and heavy metals. When both structural and ecological considerations are required, a mass ratio of 1:(0.8-1.2) balances water retention, adsorption, and structural stability.

[0012] Preferably, the prestressed anchor system includes a pre-set sleeve, an inner tube, an outer tube, and a hydraulic rod. The pre-set sleeve is installed in the revetment module, the outer tube is fixed to the revetment by threads on its outer surface, the two ends of the inner tube are fixedly connected to the pre-set sleeve and the hydraulic rod, respectively, the hydraulic rod is installed on the inner bottom surface of the outer tube, and the outer wall of the inner tube and the inner wall of the outer tube are in contact connection.

[0013] The prestressed anchor system is also equipped with a pressure sensor and a controller, the controller being electrically connected to the pressure sensor and the hydraulic rod, respectively.

[0014] The present invention has the following advantages: (1) The adaptive water flow pressure ecological revetment module of the present invention can effectively disperse and absorb the impact force of water flow through the synergistic effect of flexible materials, deformable honeycomb structure, hydraulic buffer layer and vegetation layer, reduce structural damage and improve the durability of revetment.

[0015] (2) The prestressed anchor system can dynamically adjust the prestress according to the real-time pressure, ensuring the stability of the slope and enhancing the safety of the bank protection.

[0016] (3) The establishment of vegetation layer can not only beautify the environment, but also provide ecological habitats and promote the development of biodiversity.

[0017] (4) The bank protection module has the advantages of simple structure, convenient installation and low maintenance cost, and is suitable for bank protection projects of various rivers, lakes and other water bodies. Attached Figure Description

[0024] The technical solutions in the embodiments of the invention are described clearly and completely below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1 This invention provides an ecological bank protection module that adapts to water flow pressure, comprising a flexible shell 5 (polyurethane), a variable support structure 7 (honeycomb structure, fiberglass material), a hydraulic buffer filling material 3 (plant fiber, starch and water in a mass ratio of 1:0.4:10), an ecological matrix filling material 2 (bentonite and biochar in a mass ratio of 1:1), and a vegetation layer 1 (cattail, yellow iris, loosestrife and pickerelweed).

[0026] The variable support structures 7 are interconnected to form an integral frame structure, which is installed in the flexible shell 5. The flexible shell 5 is provided with a vegetation layer 1, an ecological matrix filling material 2 and a hydraulic buffer filling material 3 from top to bottom. The hydraulic buffer filling material 3 is filled inside the variable support structure 7 to obtain the bank protection module. The bank protection module is installed on the embankment 6 through a prestressed anchor system 4. The prestressed anchor system 4 includes a pre-set sleeve 401, an inner tube 402, an outer tube 403, and a hydraulic rod. The pre-set sleeve 4 is installed in the revetment module. The outer tube 403 is fixed to the embankment 6 by threads 404 on its outer surface. The two ends of the inner tube 402 are fixedly connected to the pre-set sleeve 401 and the hydraulic rod, respectively. The hydraulic rod is installed on the inner bottom surface of the outer tube 403. The outer wall of the inner tube 402 and the inner wall of the outer tube 403 are in contact connection.

[0027] The prestressed anchor system 4 is also equipped with a pressure sensor and a controller, and the controller is electrically connected to the pressure sensor and the hydraulic rod, respectively.

[0028] The working principle is as follows: When water flows against the revetment module, the flexible outer shell 5 first absorbs the impact force, which is then transferred to the variable support structure 7. The variable support structure 7 deforms under the impact force, dispersing some of the force to the surrounding support structures. Simultaneously, the liquid in the hydraulic buffer filling material 3 begins to flow under the pressure of the variable support structure 7, and the flow resistance of the liquid further absorbs and disperses the kinetic energy of the water flow. The ecological matrix filling material 2 and the vegetation layer 1 also provide some buffering and stabilizing effects.

[0029] During the process of the revetment module being impacted by water flow, the pressure sensor built into the anchor rod monitors the pressure on the anchor rod in real time. When the pressure exceeds the preset safety value, the control system will dynamically adjust the prestressed anchor rod according to the signal fed back by the pressure sensor, increasing or decreasing the prestress of the anchor rod, that is, the depth of the anchor rod into the soil, to ensure the stability of the slope.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
