Description

Stone net {STONENET}

The present invention relates to a stone net, and in particular, a structurally stable stone net by reinforcing the rigidity of a grid made of iron wires (wires) with relatively weak rigidity to prevent the grid from being transferred and installed, or bending at the flow velocity in the installed state. On the other hand, the present invention relates to a stone net capable of improving assembly and workability and improving mutual bonding power when adjacent objects are bonded to each other.

In general, in the case of urban rivers with high land use density around rivers, slope protection works or river scour prevention works are performed to protect the slopes around the rivers.

However, the construction method of blocking with a concrete structure physically blocks the penetration of river water into the soil layer to build up vegetation plants along the natural river, while the shade provided by the vegetation along the river disappears, resulting in extreme changes in water temperature. It has lost its function as a habitat for fish and spawning, and has caused a problem of damaging the habitat of algae that take food around riverside vegetation and hide in the vegetation undergrowth.

Due to this problem, efforts have recently been made to construct more nature-friendly slopes such as river shores or slopes instead of concrete blocks, and stone net construction methods using natural stone or processed stone are known.

Meanwhile, as shown in FIG. 5, the connection nut 12 ′ according to another example of the present disclosure may be formed in a “T” shape. At this time, one side is coupled to the horizontal reinforcement 112 by a screw fastening method.

6 is a view schematically showing a reinforcing wire mesh according to the present invention.

Referring to Figure 6, the stone net according to the embodiment of the present invention further includes a reinforcing wire (13).

Like the grid 11, the reinforcing wire mesh 13 includes a wire mesh 131 made of a wire (wire), a horizontal reinforcing rod 132, and a vertical reinforcing rod 133. And, it includes a reference base 134 coupled in the vertical direction to the center of the wire mesh 131 so as to be parallel with the vertical reinforcing bar 133.

Referring to FIG. 9, the reinforcing wire 13 is fixed to the ground by a ground fixing anchor 15 while being bound to the grid 11.

The reinforced wire mesh 13 is provided with a reference base 134 serving as a reference in order to uniformly install the ground fixing anchor 15 in the center. Accordingly, the ground fixing anchor 15 can be uniformly constructed by installing the ground fixing anchor 15 at regular intervals along the reference base 134 provided in the reinforcing wire mesh 13 during construction.

10 is a view showing to explain the ground fixing anchor according to the present invention, (a) is a front view of the assembled state of the ground fixing anchor, (b) is a plan view of a socket type washer, (c) is a socket type A cross-sectional view of the washer, (d) is a plan view of the assembly nut, and (d) is a side view of the assembly nut.

Referring to FIG. 10, the ground fixing anchor 15 includes a ground bolt 151 embedded in the ground, and an anchor plate 152 that is fixed to the lower end of the ground bolt 151 and has a'V' shape to be held and supported inside the ground. ) And, a square washer 153 that is coupled to the top of the ground bolt 151 and is stuck in the ground, and a socket-type that is made of a cylindrical tube and is coupled to the top of the ground bolt 151 to press the square washer 153 to the ground It includes a washer 154 and an assembly nut 155 which is screwed to the upper end of the ground bolt 151 to press the socket-type washer 154 with a square washer 153.

In the present invention, when the ground fixing anchor 15 is constructed, the length of the ground bolt 151 must be adjusted because it cannot be driven to a certain depth according to the structure and shape of the ground at the construction site, and the assembly nut 155 ) In order to be able to be tightened to the end, a socket-type washer 154 is combined with the ground bolt 151 so as to be positioned above the square washer 153 and used.

Accordingly, as the socket-type washer 154 made of a cylindrical tube is interposed between the assembly nut 151 and the square washer 153, even if the assembly nut 151 is slightly tightened, the coarse input is applied to the socket-type washer 154. Through the transmission to the square washer 153, while improving workability, it is possible to stably construct the ground fixing anchor 15 on the ground regardless of the structure and shape of the ground.

Referring to FIG. 11, a vegetation base material 16 in which aquatic plants or aquatic organisms can inhabit may be installed, such as a vegetation mat, below the reinforcing wire mesh 13. At this time, the reinforcing wire mesh 13 and the vegetation base material 16 may be bonded to each other through the anchor plate 15 shown in FIG. 8.

12 is a view showing a state in which the gravel block is installed on the grid according to the present invention.

Referring to FIG. 12, a porous gravel block 17 is fixed to an upper portion of the grid 11 as a stone block for a stone net. And, between the porous gravel block 17, the port ball 18 is installed and fixed.

13 is a view schematically showing a porous gravel block according to the present invention.

13, the porous gravel block 17 according to the present invention is formed by attaching gravel (crushed stone or recycled aggregate) 171 to each other with an adhesive 172 to form a block, and between the gravel 171 It consists of a structure in which a void (gap) 17a is formed for permeability and ventilation.

The void 17a is formed in the gap between the gravel 171 not filled with the adhesive 172 in the gravel block 17 blocked in various shapes, for example, an amber stone shape, and air and water flow in various directions. It is continuously connected to each other so as to pass through.

In the case of applying the gravel block 17 with such voids 17a to the stone block of the stone net and constructing a floor protection hole, a shoal hole, or a drop hole, a plurality of voids 17a formed in the gravel block 17 While air and water flow through it, an environment in which various plants can vegetation is provided between them, thereby purifying water quality in an environmentally friendly manner.

The gravel 171 may be formed using natural material crushed stone or recycled aggregate. These pebbles 171 may be processed into various shapes and shapes through a processing process, and microorganisms may be coated on the surface and/or inside thereof through processing.

In the porous gravel block 17 according to the present invention, the voids 17a are continuously formed.

These voids 17a are preferably distributed in an amount of about 25% or more within the porous gravel block 17, and through this, it acts as a filter close to nature such as volcanic stone to secure water permeability and air permeability, thereby contaminants contained in the object to be purified. It can be filtered and precipitated, and decomposed and destroyed by physical and biological methods such as microbial decomposition to improve the purification function.

In addition, the void 17a adsorbs floating matter in the water flowing along the river, and microorganisms multiply in it to decompose organic carbon, nitrogen compounds, phosphorus compounds, etc., which are major substances of water pollution, and aquatic plants can grow. By creating a natural environment that can be used, the effect of water purification can be maximized.

In addition, the porous gravel block 17 according to the present invention can be produced by mixing gravel 171 as a main material (approximately 90% by weight), and an eco-friendly material, zeolite, through which water purification and The vegetation effect can be further maximized. In addition, as various shapes of irregularities (not shown) are formed on the outer surface (as the gravel block is molded and manufactured using a molding frame, various types of irregularities can be formed on the surface according to the shape of the molding frame). By increasing the surface area in contact with the water, aeration in stream flow can be improved.

14 is a flowchart showing a method of manufacturing a porous gravel block according to the present invention, and FIGS. 15 and 16 are views schematically showing each step of manufacturing a porous gravel block.

14, to prepare the gravel 171 (S11). At this time, the gravel 171 uses crushed stone or recycled aggregate, and the gravel 171 is prepared through a process of'processing → washing → drying' the aggregate.

The crushed crushed stone or recycled aggregate is processed into gravel, and the processed gravel is cleaned and dried. At this time, microorganisms can be attached to the surface of the gravel that has been dried using a vegetable adhesive that is well soluble in water, or a hole is formed on the surface of the gravel, and microorganisms are introduced into the hole, and the entrance of the hole can be sealed with a vegetable adhesive. have.

Thereafter, as shown in FIG. 15, the processed gravel 171 is put into the mold 1 (S12). At this time, the mold 1 is formed in the same shape as the shape (shape) of the porous gravel block 17 to be finally manufactured. For example, the molding mold 1 may be formed in an amber stone shape. In addition, an uneven surface corresponding to the uneven surface is formed on the inner surface of the mold 1 in order to form an uneven surface on the outer surface of the porous gravel block 17 according to the present invention.

Thereafter, as shown in FIG. 16, the adhesive 172 is put into the mold 1 into which the gravel 171 is inserted (S13). At this time, as the adhesive 172, an epoxy resin adhesive may be used alone, or a mixture in which an epoxy resin and an amine blend are mixed in a predetermined ratio may be used. As an example, the epoxy resin adhesive used as the adhesive 12 may use epichlorohydrin bisphenol A type containing a viscosity modifier.

Thereafter, the adhesive 172 is cured to complete the gravel block 17 (S14).

On the other hand, another manufacturing method of the gravel block 17 is to repeat the process of'injecting gravel → inserting adhesive → inserting gravel → inserting adhesive → inserting gravel → inserting adhesive' into the mold 1 until the mold 1 is filled. It can be carried out to form a porous gravel block (17).

17 is a flowchart showing a method of manufacturing a porous gravel block according to another example of the present invention, and FIG. 18 is a view schematically illustrating a process of spraying compressed air shown in FIG. 17.

Referring to Figure 17, the gravel preparation step (S21), the step of putting gravel into the molding (1) mold (S22), and the adhesive inputting step (S23) to the molding mold are performed in the same manner as in the embodiment described in FIG. .

Thereafter, as shown in FIG. 18, a plurality of voids 17a are formed in the adhesive 172 injected into the mold 1 by spraying strong compressed air using a nozzle on the mold 1 (S24). In this case, a plurality of the injection nozzles may be installed on the upper surface, the side surface and/or the lower surface of the molding frame 1.

Thereafter, the adhesive is cured to complete the gravel block 17 (S25).

In addition, the manufacturing method of the eco-friendly porous gravel block 17 according to another embodiment of the present invention is to stably form voids, in order to stably form pores,'inject gravel → add adhesive → spray compressed air (form pores) → insert gravel → add adhesive → put compressed air. It is also possible to manufacture the gravel block 10 by repeatedly performing the process of spraying → gravel input → adhesive injection → compressed air spraying.

As described above, in another example of the present invention, the reason why'gravel injection → adhesive injection → compressed air injection (pore formation)' is repeatedly performed in one cycle is that when forming pores in the adhesive using compressed air, the injection nozzle This is because the compressed air that is injected is interfered by the stacked gravel. That is, the purpose is to stably form voids in the adhesive by stably spraying compressed air on the adhesive connecting the gravel.

On the other hand, the eco-friendly porous gravel block 17 according to another embodiment of the present invention uses a wire or the like to puncture the adhesive attached between the gravel in a physical manner instead of forming voids by spraying compressed air to close the voids. Or, by installing an awl or a wire mesh in the molding frame, voids may be artificially formed between the gravel through them.

FIG. 19 is a view schematically showing a state in which a soft capsule is inserted into a mold for explaining a method of manufacturing a porous gravel block according to another example of the present invention.

As shown in Figure 19, the porous gravel block 17 according to another example of the present invention is a vegetable material or natural polymer (eg, gelatin, etc.) whose skin is well soluble in water after inserting gravel into the mold and before the adhesive is added. It is also possible to form a void by placing a soft capsule 173 between the pebbles 171 by inserting a soft capsule 173 made of Korean paper or the like.

When the soft capsule 173 is disposed between the pebbles 171 and dissolved or destroyed in water, it naturally forms a void between the pebbles 171. That is, when the adhesive 172 is injected, the adhesive 172 is not injected at the portion where the soft capsule 173 is disposed, and the gravel 171 is not attached to each other. Eventually, when the soft capsule 173 is melted or destroyed by exposure to water or an external impact, a void is naturally formed between the gravel 171 at the portion where the soft capsule 173 is disposed.

Various microorganisms for water purification may be embedded inside the soft capsule 173 so that the microorganisms are naturally discharged to the outside when dissolved or destroyed in the water of the soft capsule 13. Through this, contaminants on the object to be purified may be purified through microbial decomposition.

Such an eco-friendly porous gravel block according to an embodiment of the present invention may be used for natural shoals, retaining wall-type blocks, coastal erosion blocks, landscaping stones, aquatic plants, etc.

On the other hand, as shown in Fig. 12, the pot ball 18 is fixed to the grid 11 by wrapping palm fibers for pot planting so that various substances contained in the water flowing through the river are caught or stick to the aquatic plants or It can provide space for aquatic organisms to inhabit.

A brief description of the construction method of the stone net having this configuration is as follows.

First, a plurality of stone nets having the structure shown in FIG. 12 are prepared and prepared. Thereafter, stone nets are installed in the river so that the horizontal reinforcement bars of the stone nets are orthogonal to the flow velocity, and the horizontal reinforcement bars of the stone nets are bound to each other using a connection nut. Thereafter, a reinforcing wire net is placed at the bottom so as to cross the center of the stone nets disposed adjacently or cross the stone nets, and then bind to the stone nets through a binding tool, and the anchor plate Reinforced wire nets and stone nets are installed on the ground of the river.
