Side view, Figure 5 is a cross-sectional view showing a fixing member of the stone net according to the first embodiment of the present invention, Figure 6 is a cross-sectional view showing a shape including a mat member in the stone net according to the first embodiment of the present invention .

1 to 6, the stone net 1 according to the first embodiment of the present invention may include a ground layer 100, a bottom net 200 and a stone portion 300.

First, the ground layer 100 may be formed by dredging the river ground and then filling the dredging part with gravel.

Therefore, the bottom net 200 and the stone portion 300 are formed in the dredged portion so that damage and loss of the bottom net 200 and the stone portion 300 due to the flow rate can be prevented.

In addition, since the depth and flow rate of the river can be adjusted by dredging, it is possible to prevent flood damage and deterioration.

Next, the bottom net 200 is located on the top surface of the ground layer 100, both ends may be buried in the river ground.

At this time, the bottom net 200 may be composed of a geogrid.

Geogrid is a polymer structure in which various polymers and composite materials with high tensile resistance (high density polyethylene/PE, polypropylene/PP, polyvinyl alcohol/PVA, etc.) are formed in a regular lattice structure. It has high rigidity and ductility.

Therefore, when the outer surface of the bottom net 200 is deformed by the stone 300 being seated on the top surface of the bottom grid 200, the bottom net 200 can be easily torn, and the ground layer can be prevented. Since it can be deformed into a shape corresponding to (100), it is possible to prevent gravel loss of the ground layer 100.

Next, the stone portion 300 is located on the top surface of the bottom net 200, and may include a stone block 310 and a connection portion 320.

The stone block 310 may be formed of a plurality of natural stones.

At this time, the natural stone may be formed of river stones, mountain stones, granite or the like.

When the natural stone is formed of granite, the pattern and color vary depending on the type, so it is possible to select a desired design according to the flow rate and installation location of the river, thereby obtaining excellent aesthetics.

The connection part 320 is formed on the side of the stone block 310 to connect a plurality of stone blocks 310.

In addition, the connection part 320 may include a plurality of ring members 321, wires 322, U-shaped members 326 and wire connecting members 323.

The ring member 321 may include a ring body 321b inserted into the stone block 310 and a ring head 321a in the form of a ring through which the wire 322 passes.

The wire 322 may be formed in a shape that penetrates the ring head 321a to connect a plurality of ring members 321.

In addition, both ends of the wire 322 may be formed in a ring shape.

At this time, the ring head 321a of the stone block 310 is inserted into the ring shape of the wire 322 to fix the stone block 310 without additional fixing members.

Therefore, when a plurality of stone blocks 310 are formed, the ring heads 321a at both ends are fixed by the ring shape of the wire 322 to prevent the stone blocks 310 from being separated.

Accordingly, when the stone block 310 is damaged, it can be easily replaced, and the length of the wire 322 is adjustable according to the type and size of the stone block 310, and the stone block 310 according to the changing natural environment ) The clearance and spacing can be adjusted.

In addition, since the stone block 310 in the middle of the stone portion 300 formed by being connected to the wire 322 is movable according to the flow velocity of the river, the resistance generated by the flow velocity may be reduced.

The U-shaped member 326 may be composed of a body having an "U" shape with one side open and a pin penetrating the body.

At this time, the wire 322 and the bottom net 200 are inserted into the open portion of the body, and then the pin may be formed in a closed ring shape because it penetrates the end of the body.

Therefore, since the wire 322 and the bottom net 200 are constrained inside the body, the bottom net 200 and the wire 322 can be bound.

Accordingly, it is possible to have an effect that the stone portion 300 is not easily disengaged from the floor net 200 by external force after construction.

At this time, the stone unit 300 may be formed in a single layer structure, or may be formed in a stacked structure.

The wire connecting member 323 may connect between the wires 322 of the stacked stone portion 300 when the stone portion 300 is formed in a stacked structure.

At this time, gravel is provided between the stacked stone portions 300 to increase adhesion between the stacked stone portions 300.

Further, the wire connecting member 323 may include an auxiliary wire 323a and a wire sleeve 323b.

The auxiliary wire 323a may have both ends formed in a ring shape and may be configured as a stainless wire.

Since the stainless wire is not easily rusted, it can be used semi-permanently.

The wire sleeve 323b includes two holes through which the auxiliary wire 323a passes, and may include screws and screw holes on both sides.

According to this, since the wire sleeve 323b is inserted into the ring shape of the auxiliary wire 323a, the screw of the wire sleeve 323b can be tightened to form a knot, so the auxiliary wire 323a is fixed to the diameter of the wire 322 I can do it.

Therefore, it is possible to adjust the tightening strength and free position of the wire connecting member 323 by tightening the screws.

The stone net 1 may further include a mat member 400 formed between the bottom net 200 and the stone unit 300.

The mat member 400 may increase the adhesion between the bottom net 200 and the stone portion 300 to prevent movement and loss of the stone block 310 by the flow rate.

At this time, the mat member 400 may include titania phosphate.

Titania phosphate is an oxygen-reactive, non-catalyzed catalyst that continuously reacts even in matte, so it is possible to perform a surface catalytic reaction with only oxygen and water, thereby oxidizing, reducing, and decomposing organic and other contaminants by oxidation and reduction reactions.

Therefore, since it is possible to decompose and remove harmful substances, it has sterilization and antibacterial properties, and can suppress the generation of moss and mold.

The stone net 1 may further include a plurality of coupling members 330 that are formed under the stone block 310 to further fix the bottom net 200 and the stone unit 300.

At this time, the coupling member 330 may be formed on some or all of the stone blocks 310.

In addition, the coupling member 330 may include a fixing part 331 and a locking part 332.

The fixing part 331 is formed by inserting the upper end of the stone block 310 below, and the lower end of the fixing part 331 may be buried in the gravel of the ground layer 100.

At this time, the lower end of the fixing portion 331 may be formed in an arrow shape.

Therefore, not only the coupling member 330 can be easily drawn into the ground layer 100, but also the coupling member 330 is not easily separated from the ground layer 100 by external force after buried, so it can be fixed firmly. .

The locking portion 332 may be formed at the stop of the fixing portion 331.

At this time, the engaging portion 332 is formed with a hook at the end, and the bottom net 200 may be formed on the hook of the engaging portion 332.

Therefore, the ring body 321b is inserted into the stone block 310 due to weathering or the like, and the combined portion is damaged, thereby preventing the stone block 310 from being separated from the ring member 321 and lost.

In addition, since the bottom net 200 is caught by the locking portion 332, the bottom net 200 may be firmly fixed between the stone block 310 and the ground layer 100.

Meanwhile, as another example, the ring member 321 may be formed in a structure capable of being fixed at regular intervals according to the configuration of the bending wire 324 and the fixing member 325.

Hereinafter, a stone net according to a second embodiment of the present invention will be described with reference to the accompanying FIG. 7.

7 is a plan view showing a shape in which the stone parts of the stone net according to the second embodiment of the present invention are connected.

Referring to FIG. 7, the stone net according to the second embodiment of the present invention includes a configuration of the bending wire 324 and the fixing member 325 unlike the first embodiment. In addition, except for the wire 322 included in the connection portion 320 of the first embodiment may be configured in substantially the same form.

More specifically, the configuration of the connecting portion 320 of the first embodiment may include a bending wire 324 and a fixing member 325 except for the wire 322.

Therefore, hereinafter, descriptions of overlapping components will be omitted, and only the differences will be described.

The bending wire 324 penetrates the ring head 321a and may be formed in a shape connecting a plurality of ring members 321.

Also, the bent wire 324 may include a bent portion 324a.

The bent portion 324a may be formed in a'U' shape, and may be formed in a shape in which the ring head 321a is inserted into the bent portion 324a.

The fixing member 325 may fix the ring head 321a inserted in the bent portion 324a.

At this time, the fixing member 325 may include a fixing body (325a) and a bending member (325b).

The fixed body 325a may be formed in a'c' shape.

The bending member 325b is formed at both ends of the fixed body 325a, and the end may be formed in a valve shape that is bent toward the inside of the fixed body 325a.

In addition, since the opened portion of the bent portion 324a is inserted into the bent member 325b, the ring head 321a inserted in the bent portion 324a can be fixed.

That is, since the folding member 325b is formed in a plate shape, it is easy to insert but can have a difficult effect.

Accordingly, since the fixing member 325 is inserted into the bending wire 324, the ring member 321 can be fixed, and thus, it is possible to have an effect of easy assembly and repair.
