Description

Permeable Vegetation Block {A Water-penetration Vegetation Block}

The present invention relates to a vegetation block that is installed for vegetation of plants on the lake surface, such as rivers, and more particularly in the formation of a separate weight means for protecting the vegetation means for the planting and vegetation It is formed by mixing aggregate using mineral binder mainly composed of soil, which has permeability and durability, and also can solve the problems of environmental pollution such as air pollutant and alkaline water pollution due to the use of cement. By forming the weight means by using, it improves the permeability to the porous structure due to the voids formed between the aggregate and aggregate to help the dimension during heavy rains or floods, and has a porous structure and also the soil by the main stream Absorbs heavy metals such as nonpoint source or cadmium (Cd) contained in initial rainwater The present invention relates to a permeable vegetation block using a mineral binder mainly containing soil that can introduce clean water into a river or groundwater.

In order to induce vegetation of vegetation and to prevent loss and damage of the rake face, there has been a continuous attempt to induce greening on the rake face by installing vegetation mats or lance blocks in order to induce vegetation of vegetation on rivers and reservoirs.

However, conventional vegetation mats have excellent effects on inducing plant life and vegetation, but they are easily damaged due to weak durability against external impacts, and they cannot be kept in shape for a long time. Even though it is fixed construction, it is easily floated over time due to flooding or flooding, and it loses its original function of protecting the lake surface and inducing greening. In addition, the conventional vegetation mat is excellent in permeability, but the thickness is relatively thin, so that the moisturizing effect is small, so that the plant has a disadvantage in the difficulty of sliding.

In addition, since most of the conventional protection block is made of a concrete material using cement, it is strong to scour due to the durability against external impact and the flow rate of the river, while the planting and sliding of the plant is not easy. It has a strong alkalinity and adversely affects the water quality, and also has environmentally-friendly problems such as air pollution or alkaline water pollution generated while using cement. In addition, because of the impervious nature of the concrete using the cement, there is a problem of dimensions, and the appearance is not beautiful and also has the disadvantage of aesthetically low.

Hereinafter, preferred embodiments of the permeable vegetation block according to the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a perspective view of a permeable vegetation block according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the vegetation block of FIG. 1, and FIG. 3 is an enlarged view of an enlarged portion of the weight means in the vegetation block of FIG. 1. 4 is a state diagram in which the vegetation block of FIG. 1 is constructed in a lake, and FIG. 5 is a photograph of the specimen used in the test.

1 to 4, the permeable vegetation block 10 according to an embodiment of the present invention is a vegetation means 110 for supplying nutrients for plant growth; It includes the vegetation means 110, and the weight means 130 is formed on the top of the planting hole 140 to plant the plant pot; may be formed.

The vegetation means 110 is a configuration for supplying the nutrients necessary for plant growth, it is not limited to the shape and structure as long as the plant can be supplied to the nutrients and moisture. The vegetation means 110 may be formed in a form that is mixed with coconut fiber, coco peat, bark, etc. Preferably, the vegetation means 110 is a nutrient required for plant growth as shown in FIG. Vegetation base material (111) for supplying and providing an effective soil required for root rooting; It may be formed in the form including a; surrounding the vegetation base material 111 seat sheet 112 to prevent the vegetation base material is leaked to the outside.

The vegetation base material 111 is configured to supply nutrients and moisture to the plant roots slid to the vegetation block 10 according to the present invention so that the plant can be vegetated smoothly, for this purpose the vegetation base material 111 Coco pits, bark and the like as a main component can be made by blending sawdust, rice husk, rice straw, charcoal, persimmon skin and the like. Among the above ingredients, coco peat, sawdust, rice husk, rice straw itself contains a large amount of organic matter, which can supply nutrients for vegetation of plants, and in particular, because it forms a large amount of pores, If rainwater penetrates due to rainfall, it can absorb moisture and store it for a long time, provide it to plant roots, and perform a filter function to adsorb contaminants contained in water. In addition, in the case of charcoal or persimmon among the components has a purification function to purify the water it is possible to purify the water passing through the vegetation base material (111).

The sheet part 112 is configured to prevent the vegetation base material from leaking to the outside by surrounding the vegetation base material 111, and as the sheet part 112, a coir fiber or a coconut sheet may be utilized. have. The sheet portion 112 is able to protect the vegetation base material 111 contained therein from the external impact, such as during transportation or construction process or construction by surrounding the vegetation base material 111 as a whole. Coir fiber or coconut sheet constituting the sheet portion 112 is a natural material that is naturally decomposed after a certain time after construction has an environmentally friendly advantage. However, the filling of the vegetation base material 111 included in the sheet part 112 is prevented from escaping to the outside, and also prevents plant seeds of different types introduced from the outside from penetrating into the vegetation base material 111 to be planted. In order to process a separate latex coating on the sheet portion 112. Such a latex coating may be manufactured by applying a latex on a coir fiber (coconut sheet) and then compressing it to form a sheet. The latex treatment of the sheet portion 112 formed as described above can effectively protect the vegetation base material 111 filled therein by reinforcing the rigidity of the coir fiber (coconut sheet) to prevent it from being easily decomposed by moisture penetration. Of course, by using the pores formed in the pores of the latex itself and coir fiber (coconut sheet) so that the roots of the sliding plant can be easily supplied with nutrients and moisture from the vegetation base material 111 is filled inside In particular, it is possible to prevent heterogeneous plant seeds from invading from the outside to penetrate into the vegetation base 111.

The weight means 130 includes the vegetation means 110 therein, the planting hole 140 is formed on the top to specifically plant the plant pot, the vegetation block 10 of the present invention Is the part that forms the outermost surface of the. In particular, unlike the conventional vegetation block or vegetation mat, the weight means 130 has a feature that the vegetation block itself installed on the inclined surface by itself its weight can be firmly fixed. In addition, the weight means 130 is formed by mixing the aggregate using a mineral binder mainly composed of soil, so as to have a permeability and durability, as well as to solve the problem of environmental pollution due to the use of cement, and also, cement Instead, the use of mineral binder solves environmental problems such as air pollutant and alkaline water pollution generated by using cement, and the gap formed between aggregate and aggregate by forming weight means using aggregate of about 5mm. Due to the porous structure, the water flowing into the stream is easily passed through the vegetation block (weight means), so that the pollutant is adsorbed, or has a characteristic to help the dimensions during heavy rains or floods. In addition, the weight means 130 in the present invention, as shown in Figure 2, etc., the upper surface and the side including the planting hole 140 is integrally formed to form a space for accommodating the vegetation means 110 therein A first weight means 131 and a second weight means 132 press-fitted to the lower portion of the first weight means 131 to form a lower surface, and the vegetation in the space formed in the first weight means 131 After inserting the vegetation means 110 formed of the base material 111 and the seat portion 112, the second weight means 132 is simply pressed by combining the second weight means 132 on the lower surface of the first weight means 131 130 can be installed to install the vegetation block 10 including the vegetation means 110 inside. In addition to the planting hole 140 is formed in order to be able to plant the plant pot on the upper portion of the first weight means 131, the additional planting hole 140 is additionally added to the second weight means 132. It can form for the rooting of plant roots or for the smooth movement of moisture and nutrients.

In the present invention, the weight means 130 is characterized in that the aggregate is formed by mixing the aggregate using a mineral binder mainly composed of soil, hereinafter will be described in detail the characteristics of the components.

The weight means 130 is 10 to 30% by weight of soil, 15 to 50% by weight of magnesium oxide, 15 to 40% by weight of blast furnace slag, 5 to 10% by weight of phosphate fertilizer, 10 to 40% by weight of volcanic soil, wollastonite 5 100 parts by weight of a powder raw material consisting of 10 wt%; 30 to 70 parts by weight of a liquid raw material consisting of 10 to 60% by weight of magnesium chloride, 1 to 8% by weight of phosphate, and 32 to 89% by weight of water (fresh water or seawater), and 15 to 25% by weight of a mineral binder, ii It is characterized by consisting of 75 ~ 85% by weight aggregate of 2 ~ 8mm particle size.

The soil may be used mud clay such as red clay (red clay) and ocher, and sandy soil such as kaolin, white clay and masato, which are generally obtained from the surface of the soil, and the type of soil is not particularly limited. It is preferable that 55% by weight of fine granules (0.8 mm or less) and particles of granules (greater than 0.8 mm to less than 2 mm) are properly mixed at a ratio of about 45%. In particular, in the present invention, it is preferable to use the topsoil generated during various mining activities in which the properties of various static clay particles are evenly mixed. Topsoil contains small soil particles and aggregate fines. The amount of the soil used in the powder raw material is 10 to 30% by weight, in the case of less than this range, as the content of the soil is lowered, the efficiency of recycling of the soil is lowered as well as the adsorption capacity known as the unique performance of the soil. There is a problem in that the adsorption capacity of heavy metals such as cadmium (Cd) is lowered, and if it exceeds this range, the adsorption performance is excellent, but due to the interlayer structure of tetrahedron and octahedron with many silt components of soil and soil As the liquid phase is absorbed, the economical efficiency decreases due to the use of excess liquid, and in particular, the compressive strength is remarkably lowered due to the use of excess liquid and plasticity of the soil. Will occur.

The magnesium oxide is not particularly limited, but magnesium oxide obtained by heat-treating magnesium oxide extracted from dolomite, light magnesium, and magnesium hydroxide extracted from seawater may be used. Preferably, magnesium oxide obtained by heat-treating light magnesium and dolomite is used. It is. The higher the purity of magnesium oxide is, the more preferable it is, but from an economical point of view, it is appropriate for 90% to have purity. Magnesium oxide acts to form an inorganic complex by reacting with each other by the addition of chlorine inorganic mixed solution composed of blast furnace slag, phosphate fertilizer, and magnesium chloride and phosphate. The principle of the coupling reaction is based on the ionic reaction, and more specifically, the magnesium phosphate solidification principle. However, the biggest weakness of magnesium-based hardeners, which has been used previously, is water resistance, that is, the binder product reacts with water to change the product phase due to the problem of contact with water. It has been used indoors. Combined by the added raw materials to produce the product of 5Mg (OH) ₂ · MgCl ₂ 8H ₂ O and 3Mg (OH) ₂ · MgCl ₂ 8H ₂ O, and the blast furnace slag was added to the acidic liquid The gypsum component contained in CaO, SiO ₂ and volcanic earth by ion dissolving can produce ettringite gel, which can solve the problem of water resistance, which was a problem of the conventional magnesium-based binder. In addition, the ion-eluted Si ions act in combination, one acting as a generating factor of the etlingzite gel described above, and producing MSH (magnesium silicate hydrate). The proper amount of use is 15 to 50% by weight, and if it is less than this range, there is a problem of showing a very low bonding strength that cannot act as a binder. If this range is exceeded, the bonding strength acts strongly to express compressive strength. Is very excellent, but water resistance has a problem such as cracks due to the contact of rain water, the problem of deterioration of the adsorption capacity of heavy metals aimed at the present invention due to the reduction of the amount of other raw materials used.

The blast furnace slag is produced as a by-product when producing pig iron in the blast furnace, but is not particularly limited, but it is preferable to use a powder degree (Blaine) of 7,000 cm 2 / g. In the examples below, 7,000 cm 2 / g produced and sold from the Basic Materials Research Institute Co., Ltd. was used, and the composition of the chemical phase is not particularly limited. Unlike the soil composition, the chemical composition of blast furnace slag is 88.6% by weight of SiO ₂ + Al ₂ O ₃ + CaO, other minor components account for 11.4% by weight, and blast furnace slag improves the water resistance of the binder. It was used for the purpose of improving densification. Blast furnace slag is damaged by acidic group of chlorine inorganic solution, from which Si ions, Ca ions, and Al ions are leached, and Ca ions produce Ca (OH) ₂ , which is present in magnesium dioxide and phosphate fertilizer. MgO generates Mg (OH) ₂ to weakly alkalize the liquid of the product, and the eluted ions recombine to produce an ettringite and a CSH gel and to generate an MSH gel. The suitable amount is 15 to 40% by weight, and if it is less than this range, there is a problem that the water resistance is weakened due to the insufficient amount of product of CSH gel and ettringite, which are water-resistant substances for magnesium-based products. There is a problem that the magnesium-based material is not used as a packaging material because the strength decreases as the usage amount decreases. In addition, there is also a problem that the liquid retention of pH 10 or less, which is the object of the present invention, cannot be achieved by excessive use of blast furnace slag.

The phosphate fertilizer is generally one of phosphate fertilizers that are sold for agriculture, and is composed of phosphoric acid, goto (magnesium oxide), lime, silicic acid, sulfur, and more specifically, phosphate fertilizer known as yongguarin. Goto phosphate fertilizer is a water-soluble phosphate group and contains magnesium oxide, lime, silicic acid, and sulfur, and includes elements suitable for the bonding principle of the present invention, and these various ions include 5Mg (OH) ₂ · MgCl ₂ · 8H _2. The product of O and 3Mg (OH) ₂ · MgCl ₂ · 8H ₂ O prevents the Mg (OH) ₂ phase transition by contact with water, thereby improving water resistance. In addition, because the use of fertilizers have a feature that can be utilized as a fertilizer of the soil by grinding even when discarded products developed and produced by the present application. An appropriate amount is 5-10% by weight, in the case of less than the range, a _{5Mg (OH) 2 · MgCl 2} · 8H 2 O and _{3Mg (OH) 2 · MgCl 2} · Mg (OH) of the product _2, 8H ₂ O As the transition occurs, cracks and cracks are generated, and if it exceeds this range, problems of strength drop occur due to the lack of economical efficiency due to the use of expensive phosphate fertilizer and the action of preventing the reaction of the added raw materials.

The volcanic soil is volcanic soil composed of crystalline phases of boehmite (Al (OH) ₃ ), quartz and gypsum (calcium sulfate hydrate), which are well known for their adsorption capacity of heavy metals, and SiO ₂ and Al ₂ O ₃ 40 wt% and 20.2 wt%, SO ₃ 12.9 wt%, CaO 11.9 wt% respectively. Boehmite has excellent adsorption capacity of heavy metals, and gypsum acts to improve the water resistance of magnesium-based composites. Appropriate amount of use is 10 to 40% by weight, and if it is less than this range, there is a problem of insufficient adsorption performance, and if it exceeds this range, the amount of other raw materials is reduced by excessive use, and the compressive strength is rapidly increased. There is a problem that can not be achieved to achieve the target compressive strength.

The wollastonite is not particularly limited in the present invention. Wollastonite was used as a reinforcing material to reinforce the bendability of the soil permeable pavement material proposed in the present invention as needle-shaped particles, and wollastonite, which is one of the mineral needle-like materials, was used in accordance with the prohibition of the use of representative asbestos of fibrous minerals. . Minerals that can be used as fibrous materials may be haemulite (sepiolite), ceramic fiber (spray method), glass fiber, and wollastonite and haemulite are most preferred. The suitable amount is 5 to 10% by weight, and if it is less than this range, strong compressive strength is expressed, but due to the lack of fiber, there may be a problem that a long cut to the transverse or longitudinal axis of the pavement is caused by a car or a motorcycle. If it exceeds, the compressive strength is significantly lowered, and the amount of binder and the amount of soil, including volcanic soil, are relatively small, resulting in problems of the expression of target adsorption performance and water resistance.

In the present invention, chlorine inorganic solution is used magnesium chloride and phosphate. Magnesium chloride is generally known as a brine, and the chemical formula is MgCl ₂ · 5H ₂ O, and magnesium chloride is an MSH gel, CSH gel and 5Mg (OH) ₂ · MgCl ₂ · 8H ₂ O and 3Mg (OH ) Plays a dominant role in the production of ₂ · MgCl ₂ · 8H ₂ O phases. Phosphate acts to acidify the liquidity of magnesium chloride and to produce phosphate compound which is one of the final products, and it is acidic in phosphate, H ₃ PO ₄ , KH ₂ PO ₄ , NaH ₂ PO ₄ , Na ₂ H ₂ P ₂ O ₇ , (NaPO ₃ ) _{5 ~ 9,} etc., Magnesium dioxide, wollastonite, blast furnace slag are stimulated by these phosphate groups, and are ion-eluted, respectively, Mg ²⁺ , Ca ²⁺ , Al ³⁺ , It is ionized with Si ⁴⁺ and the like, and the added phosphate group reacts to form a hydroxyapatite-based calcium phosphate compound, and magnesium ions and aluminum ions are hydrotalcite (Mg ₄ Al ₂ (OH) ₁₂ CO ₃ · 3H ₂ O) acts to produce. The proper amount of magnesium chloride is 10 to 60% by weight, and if it is less than this range, the bonding strength is lowered, so it cannot act as a binder. As a result, a problem that cannot be produced in liquid form occurs. The proper amount of phosphate is 1 to 8% by weight, and if it is less than this range, the liquid liquidity becomes the neutral zone, so that the blast furnace slag cannot be effectively stimulated, and the water resistance that is intended based on this cannot be expected. In the case of exceeding this range, the use of excessive phosphate is not as economical as the use of phosphate fertilizer. In recent years, the price of phosphate has risen sharply, raising the cost of products using it. Currently, the price of phosphate, especially acidic phosphate, has been set at over 4500 won per kg. It takes up more than 50% of the ratio is a problem that the competitiveness with other binders deteriorate.

Water can be either seawater or freshwater, and the appropriate amount is 32 to 89% by weight.

The aggregate is a main configuration for forming the weight means 130 of the vegetation block of the present invention, it is preferable that the aggregate of 2 to 8mm particle diameter is composed of 75 to 85% by weight. Aggregate having the diameter as described above is able to form and maintain the strength of the weight means 130, as well as to ensure the water permeability by the gap formed between the aggregate particles and the particles.

In the present invention, the use ratio of the powdery raw material and the liquid raw material is suitably 100: 30 to 70 weight ratio. More preferably, 100: 40-60 weight ratio is good. If the amount of the liquid raw material is less than the above range, there is a problem that can not be molded, if it exceeds the above range, the flowability is high and flows through the gap when the raw material is placed in the mold or mold, or solid and liquid phase during filling molding This separation problem occurs and finally leads to a decrease in compressive strength, which is undesirable.

Hereinafter is an experiment for confirming the physical properties of the weight means used in the present invention.
