Description

Technical Field

[0001] This invention belongs to the field of riverbank slope protection technology, specifically relating to an ecological bank protection method and structure using biomass fuel. Background Technology

[0002] As people increasingly emphasize ecological and environmental protection, environmental maintenance needs to be given high priority in all sectors. Riverbanks not only need to meet basic requirements such as flood control, but also need to possess ecological and green functions.

[0003] Currently, the main methods for riverbank restoration include traditional revetment and ecological revetment. Traditional revetment types include dry-laid stone revetment, mortar-grouted stone revetment, cast-in-place concrete revetment, and precast concrete block revetment, generally using hard materials such as cement and stone. While these methods offer advantages such as maintaining slope stability, preventing soil erosion, flood control and drainage, and erosion resistance, they also have a certain impact on the ecological environment. Because hard materials like concrete and stone have low porosity and poor permeability, covering the entire slope isolates the material cycle between water, soil, and microorganisms, weakening the water's self-purification capacity and affecting the original natural characteristics of the slope. This ultimately damages the entire slope's ecosystem and does not meet the requirements of green development.

[0004] Types of ecological bank protection include planted bank protection, ecological concrete bank protection, and ecological brick bank protection. These generally utilize materials such as planted concrete layers and plants. While this type of bank protection can provide some ecological protection, some problems still exist.

[0005] (1) Planting plants to protect the bank: Bank protection is easily eroded by rainwater into deep gullies, resulting in poor bank protection effect, affecting the landscape, and slow results. It is difficult to directly improve the bank slope environment by planting plants.

[0006] (2) Ecological brick revetment: Because there is no bonding force between ecological bricks, the overall stability is poor.

[0007] With the continuous improvement of development levels, the consumption of non-renewable energy has been rising, and the energy shortage problem has become increasingly prominent. At the same time, the environmental pollution caused by the consumption of non-renewable fuels has also attracted widespread attention. To address the shortage of non-renewable energy, improve the ecological environment, and restore riverbank slopes, it is imperative to develop a new, environmentally friendly, and low-cost ecological bank protection method. Biomass fuel, as a clean energy source, is made by crushing, compressing, and drying agricultural and forestry waste such as rice husks, straw, and fallen leaves, and then compressing them into the required shape for direct combustion. Its combustion process primarily emits carbon dioxide, with no harmful gases such as sulfur dioxide; it has significant characteristics such as being pollution-free and renewable. Furthermore, biomass energy consumption is second only to coal, oil, and natural gas; therefore, biomass energy can not only replace fossil fuels but also protect the environment. Applying biomass fuel to bank slope restoration is convenient in terms of material availability and low cost, while simultaneously creating a natural living environment for microorganisms on the bank slope surface, promoting ecological circulation. This invention provides a simple, novel, environmentally friendly, and low-cost ecological bank protection method and structure using biomass fuel combustion. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this invention is to provide an ecological bank protection method and structure using biomass fuel combustion. This method utilizes hollow cylindrical molds and hollow biomass rods made from biomass fuel. After covering the concrete layer, the hollow cylindrical molds and hollow biomass rods are burned to form cylindrical holes and channels, facilitating the injection of slurry. This allows the concrete layer and plant roots to bond tightly, thereby enhancing the stability of the bank slope.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0010] An ecological bank protection method using biomass fuel includes the following steps:

[0011] Step 1: Clean the bank slope: Remove any protruding debris from the surface;

[0012] Step 2, Laying the mold: The revetment mold includes hollow cylindrical molds and hollow biomass rods, both made of biomass fuel. The lower part of the hollow cylindrical mold has two rows of centrally symmetrically distributed insertion holes. Each insertion hole can accommodate a hollow biomass rod. Adjacent hollow cylindrical molds are connected by the hollow biomass rods inserted into the insertion holes. Multiple hollow cylindrical molds and multiple hollow biomass rods are arranged in a mesh structure on the bank slope.

[0013] Step 3: Secure the mold using fasteners;

[0014] Step 4, Shotcrete layer: Spray the mixed concrete layer evenly onto the slope surface and cover it with two rows of biomass hollow rods, without submerging the upper part of the hollow cylindrical mold;

[0015] Step 5, burning the molds: After the concrete layer is formed, burn the hollow cylindrical mold and the biomass hollow rod, leaving a cylindrical hole corresponding to the shape of the hollow cylindrical mold on the surface of the concrete layer and a duct corresponding to the shape of the biomass hollow rod inside the concrete layer;

[0016] Step 6, spraying slurry: Spray slurry into the cylindrical hole, and the slurry flows into the internal duct along the inclined angle of the bank slope;

[0017] Step 7, sowing plants in the cylindrical hole and covering with a surface layer;

[0018] Step 8, bank surface maintenance: Carry out atomized spraying.

[0019] Furthermore, in Step 2, the bank slope is divided into multiple areas, and the bank protection molds are laid in the multiple areas in sequence.

[0020] Furthermore, in Step 3, the fixing member is a U-shaped anchor rod. One end of the fixing member is bent into a U shape and sleeved on the biomass hollow rod, and the other end is a cantilever end and nailed into the bank slope.

[0021] Furthermore, in Step 5, before burning the bank protection mold, fill the horizontal biomass hollow rod with planting soil.

[0022] Furthermore, in Step 7, the main raw material of each cubic meter of the surface layer is soil binder, with a volume ratio of 0.01%-0.02%, and 800-1000 g / m

[0028] , <000,00058>,

[0026] , , , , providing the nutrition required for the early growth of plants.

[0023] Furthermore, in Step 7, the plants are Lespedeza bicolor or Amorpha fruticosa.

[0024] Furthermore, in Step 2, the hollow cylindrical mold and the biomass hollow rod are made by crushing, extruding, and drying biomass fuel.

[0025] Furthermore, in Step 2, the hollow cylindrical mold is evenly distributed with 8 holes in each layer. The wall thickness of the hollow cylindrical mold is 2-3 cm, the outer diameter is 18-22 cm, and the height is 18-22 cm.

[0026] Furthermore, each hollow cylindrical mold is provided with two rows of 8 jacks distributed symmetrically about the center, and each jack is inserted with the biomass hollow rod to form a "rice" shaped structure.

[0027] An ecological bank protection structure burning biomass fuel, comprising:

[0028] The bank protection mold includes hollow cylindrical molds and hollow biomass rods, both made of biomass fuel. The lower part of the hollow cylindrical mold has two rows of centrally symmetrically distributed insertion holes. Each insertion hole can accommodate a hollow biomass rod. Adjacent hollow cylindrical molds are connected by the hollow biomass rods inserted into the insertion holes. Multiple hollow cylindrical molds and multiple hollow biomass rods are arranged in a mesh structure on the bank slope.

[0029] The fastener is fitted onto the hollow biomass rod at one end and nailed into the bank slope at the other end.

[0030] The process involves laying the revetment mold on the bank slope and fixing it with the fixing components. A cast-in-place concrete layer submerges the two rows of biomass hollow rods but does not submerge the upper part of the hollow cylindrical mold. After burning the revetment mold, cylindrical holes and channels are formed. The channels are below the concrete layer. Mud is poured into the cylindrical holes so that the mud flows along the channels to cover the entire bank slope. Plants are then sown and a surface layer is applied.

[0031] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0032] (1) The present invention uses a concrete layer that encloses the internal channels, making it difficult for the planting soil to be lost; and the internal through channels can provide sufficient growth space for the plants. Compared with existing planted bank protection technologies, this invention solves the problems of weak erosion resistance and limited plant growth environment.

[0033] (2) The concrete layer of the present invention is cast-in-place, which has strong integrity and erosion resistance, and can greatly improve the protection effect of the bank slope. The internal through-holes are achieved by incineration, so the integrity of the concrete layer is not damaged.

[0034] (3) The hollow cylindrical mold and the ash produced after burning the biomass hollow rods of the present invention can be used as high-quality organic potassium fertilizer to provide nutrients for plants. This provides a benign material cycle environment and promotes the cycle of the bank slope ecosystem.

[0035] (4) This invention mainly uses biomass energy as the combustion material. Biomass fuel is a widely used clean energy source with a wide range of applications, such as domestic heating and thermal power generation. It does not produce harmful substances such as sulfur dioxide and phosphorus pentoxide during combustion, and therefore does not pollute the atmospheric environment.

[0036] (5) The mesh structure composed of biomass hollow rods and hollow cylindrical molds can replace metal mesh and play a role in stabilizing the concrete layer during the early spraying of concrete layers; at the same time, it can reduce costs and is more environmentally friendly.

[0037] (6) The materials used in this invention are readily available and, to a certain extent, alleviate the problem of how to deal with agricultural waste, turning waste into treasure and greatly reducing material costs.

[0038] (7) The hollow cylindrical mold of the present invention will leave holes in the concrete layer after burning. The size of the holes is the same as that of a flower pot for planting herbaceous plants. The crisscrossing hollow biomass rods form channels under the concrete layer, which can provide enough space for the growth of plant roots, so that the concrete layer and plant roots are tightly connected and the stability of the bank slope is enhanced.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0049] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0050] This invention provides an ecological bank protection method using biomass fuel, such as... Figures 1-3 As shown, it includes the following steps:

[0051] Step 1: Clean the bank slope: Remove protruding debris such as rocks and branches from the surface to facilitate the subsequent laying of molds and sprayed concrete layer 4;

[0052] Step 2, Laying the mold: The revetment mold includes a hollow cylindrical mold 1 and a hollow biomass rod 2, both made of biomass fuel. The lower part of the hollow cylindrical mold 1 has two rows of centrally symmetrically distributed insertion holes. Each insertion hole can accommodate a hollow biomass rod 2. Adjacent hollow cylindrical molds 1 are connected by the hollow biomass rods 2 inserted into the insertion holes. Multiple hollow cylindrical molds 1 and multiple hollow biomass rods 2 are arranged in a mesh structure on the bank slope.

[0053] Step 3: Secure the mold with fastener 3 to prevent it from slipping when spraying the concrete layer 4 later;

[0054] Step 4, Shotcrete Layer 4: The mixed concrete layer 4 is evenly sprayed onto the slope surface using a cast-in-place method, covering two rows of biomass hollow rods 2, without submerging the upper part of the hollow cylindrical mold 1. The thickness of the concrete layer 4 is less than the height of the hollow cylindrical mold 1 to prevent the concrete layer 4 from submerging the hollow cylindrical mold 1 and making it unusable. The segmented cast-in-place concrete layer 4 is to prevent overall damage caused by local settlement.

[0055] Step 5, Burning the mold: After the concrete layer 4 is formed, the hollow cylindrical mold 1 and the biomass hollow rod 2 are burned. After burning, cylindrical holes corresponding to the shape of the hollow cylindrical mold 1 will be left on the surface of the concrete layer 4, and channels corresponding to the shape of the biomass hollow rod 2 will be left inside the concrete layer 4.

[0056] Step 6, spraying mud: After burning, spray mud into the cylindrical holes left in the concrete layer 4, and the mud can flow into the internal channels along the slope of the bank, so that the plant roots can grow easily.

[0057] Step 7: Sow the plants in the cylindrical holes and cover them with a layer of foliar material to provide the nutrients the plants need to grow.

[0058] Step 8, Shore surface maintenance: The shore surface maintenance uses a sprinkler system, maintaining a moderate atomization spray during the spraying process.

[0059] This invention provides an ecological bank protection method using biomass fuel combustion. The method employs a concrete layer 4, which encloses internal pores, preventing soil loss and providing ample growing space for plants. Compared to existing plant-based bank protection techniques, this method solves problems such as weak erosion resistance and limited plant growth environment.

[0060] This invention provides an ecological bank protection method using biomass fuel combustion. The concrete layer 4 is cast-in-place, exhibiting strong integrity and erosion resistance, which significantly improves the bank slope protection effect. The internal through-holes are achieved through combustion, thus preserving the integrity of the concrete layer 4.

[0061] This invention provides an ecological bank protection method using biomass fuel combustion. The ash produced after burning the hollow cylindrical mold 1 and the hollow biomass rods 2 can serve as high-quality organic potassium fertilizer to provide nutrients for plants. This creates a healthy material cycle environment and promotes the circulation of the bank slope ecosystem.

[0062] This invention provides an ecological bank protection method using biomass fuel, primarily employing biomass energy as the combustion material. Biomass fuel is a widely used clean energy source with broad applications, such as residential heating and thermal power generation. It does not produce harmful substances like sulfur dioxide and phosphorus pentoxide during combustion, thus avoiding atmospheric pollution.

[0063] An ecological revetment method for burning biomass fuel provided by the present invention. The net structure composed of the biomass hollow rods 2 and the hollow cylindrical molds 1 can replace the metal net, and can play a role in stabilizing the concrete layer 4 during the early spraying of the concrete layer 4. Moreover, two rows of jacks symmetrically distributed around the center are provided in the middle and lower parts of the hollow cylindrical molds, and each jack can insert a biomass hollow rod 2. Adjacent two hollow cylindrical molds are connected through the biomass hollow rods 2 inserted in the jacks. Multiple hollow cylindrical molds and multiple biomass hollow rods 2 are arranged in a net structure on the bank slope, leaving enough space for the growth of plant roots. If only one row of jacks is set, the growth roots of plants are not firm enough. If more than 3 rows of jacks are set, too thick concrete layer needs to be covered, resulting in too high cost. Therefore, the present invention can reduce the cost and is more friendly to the environment.

[0064] An ecological revetment method for burning biomass fuel provided by the present invention uses materials that are convenient to obtain. At the same time, it alleviates the problem of how to solve agricultural waste to a certain extent, turning waste into treasure and greatly reducing the material cost.

[0065] The hollow cylindrical mold 1 and the biomass hollow rod 2 are made by crushing, extruding, and drying biomass fuel. As Figure 5 shown, the wall thickness of the hollow cylindrical mold 1 is 2 - 3 cm, the outer diameter is 18 - 22 cm, and the height is 18 - 22 cm. At the same time, two rows of holes are opened in the middle and lower parts of the hollow cylindrical mold 1. There are 8 holes in each row, and the diameter of each hole is 5 cm; the 8 holes in each layer are symmetrically distributed around the center of the hollow cylindrical mold 1, and the distance between the two layers of holes is 2 cm.

[0066] As Figure 7 shown, each of the hollow cylindrical molds 1 has two rows of 8 jacks symmetrically distributed around the center, and each jack inserts the biomass hollow rod 2, forming a double-layer "rice" - shaped structure. The distance between two adjacent hollow cylindrical molds 1 in the horizontal and vertical directions is 25 cm. The manufacturing process of the biomass hollow rod 2 is the same as that of the hollow cylindrical mold 1. Three sizes of biomass hollow rods 2 are made, with a wall thickness of about 1 cm, an outer diameter of 5 cm, a length of 30 cm, a wall thickness of about 1 cm, an outer diameter of 5 cm, a length of 40 cm, a hole with a diameter of 4 cm opened in the middle, and a wall thickness of about 1 cm, an outer diameter of 4 cm, and a length of 40 cm. Among them, the two longer biomass hollow rods 2 are used to connect two obliquely adjacent hollow cylindrical molds 1, and the biomass hollow rod 2 with an outer diameter of 4 cm passes through the hole reserved in the middle of the biomass hollow rod 2 with an outer diameter of 5 cm; the shorter biomass hollow rods 2 are used to connect two horizontally adjacent hollow cylindrical molds 1 or two vertically adjacent hollow cylindrical molds 1.

[0067] The biomass fuel of the present invention is obtained by pulverizing, extruding, drying and other treatments of agricultural and forestry waste such as straw and dead leaves, and adding a combustion aid at the same time; then it is compressed into a shape. Since the biomass itself contains macromolecular substances such as cellulose, lignin, and starch. These substances play a binding role under certain temperature and humidity conditions, making the formed mold not easy to break.

[0068] Preferably, the combustion aid of the present invention is biomass liquefied oil. When using a blowtorch to burn the hollow cylindrical mold 1, since the hollow cylindrical mold 1 and the biomass hollow rod 2 are hollow, and at the same time the distance between the hollow cylindrical molds 1 is short and the combustion aid is added, it burns more fully.

[0069] The slurry of the present invention is mainly planting soil and is used for the growth of plants.

[0070] As Figure 6 shown, the fixing member 3 of the present invention is a U-shaped anchor rod. One end of the U-shaped anchor rod is bent into a U shape, and the other end is a straight-end metal anchor rod. Fixing the biomass hollow rod 2 is to prevent the shaking and instability of its network structure during the spraying of the concrete layer 4, resulting in the detachment of the connection.

[0071] In step 5, the slurry in the pore flows in along the angle of the bank surface. Since the horizontal biomass hollow rod 2 is in the horizontal direction and has no inclined angle. Before burning the revetment mold, the planting soil is poured into the horizontal biomass hollow rod 2.

[0072] The concrete layer 4 of the present invention is composed of cement, sand, gravel, and water.

[0073] The main surface layer raw material per cubic meter of the present invention is a soil binder, with a volume ratio of 0.01%-x0.02%, and compound fertilizer 800 - 000 g / m 3 , providing the nutrients required for the early growth of plants.

[0074] The plants of the present invention are Lespedeza bicolor or Amorpha fruticosa. Such plants have strong adaptability and are not strict with soil requirements.

[0075] The "rice" - shaped structure is formed by the criss - cross connection of the biomass hollow rod 2 and the hollow cylindrical mold 1. When forming the concrete layer 4, it can play a role in stabilizing the concrete layer 4 like a metal net in the initial stage. Due to the large scale of the bank slope, when laying the mold, in order to facilitate the laying of the revetment mold, the bank slope is divided into multiple areas, and the revetment mold is laid in multiple areas in sequence. Specifically, it can be laid in areas divided by 5m * 5m, and the thickness of the sprayed concrete is 18 cm, which can prevent the mold from falling off during the overall laying.

[0076] The present invention also provides an ecological revetment structure for burning biomass fuel, as Figure 1-3 shown, including:

[0077] The bank protection mold includes a hollow cylindrical mold 1 and a hollow biomass rod, both made of biomass fuel. The lower part of the hollow cylindrical mold 1 has two rows of centrally symmetrically distributed insertion holes. Each insertion hole can accommodate a hollow biomass rod 2. Two adjacent hollow cylindrical molds 1 are connected by the hollow biomass rods 2 inserted into the insertion holes. Multiple hollow cylindrical molds 1 and multiple hollow biomass rods 2 are arranged in a mesh structure on the bank slope.

[0078] The fastener 3 is fitted onto the biomass hollow rod 2 at one end and nailed into the bank slope at the other end.

[0079] The process involves laying the revetment mold on the bank slope and fixing it with fasteners 3. The cast-in-place concrete layer 4 submerges the two rows of biomass hollow rods 2 but does not submerge the upper part of the hollow cylindrical mold 1. After burning the revetment mold, cylindrical holes are formed on the concrete surface and channels are formed below the concrete layer 4. Mud is poured into the cylindrical holes so that the mud flows along the channels to cover the entire bank slope. Plants are then sown and the surface layer is covered.

[0080] The mesh structure composed of biomass hollow rods 2 and hollow cylindrical molds 1 can replace metal mesh. It can stabilize the concrete layer 4 during the early spraying of concrete layer 4, and the formed channels leave enough space for plant roots to grow, so that the concrete layer and plant roots are closely connected, thereby enhancing the stability of the bank slope.

[0081] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
