Description

Slope Stabilization Structure and Rust Frame {STRUCTURE FOR STABLIZING INCLINED PLANE AND PLANTING BLOCK}

The present invention relates to a slope stabilization structure and rust frame, more specifically, by treating the tailings / waste ore or soil of the waste mine in a natural manner, water pollution, soil pollution and water pollution by heavy metal leaching, acid mine drainage and turbidity in rainy weather It relates to an inclined surface stabilization structure and rusted frame to prevent the, and to prevent air pollution due to the scattering of fine particles.

In general, tailings / waste ores that have no economic value in mines are left unattended around the abandoned mines after they are abandoned.

The tailings / waste ore contains a large amount of heavy metals, causing water pollution, soil pollution and water pollution by heavy metals eluted during rainy weather.

In addition, because the tailings / waste ore contains fine particles, air pollution is caused by the fine particles scattered by the wind.

A method of stabilizing tailings / waste ore is to prevent various contaminations, and includes a slope vegetation method and a solidification method.

The slope vegetation method is a method of applying tailings / waste ore with mud and vegetation on mud. Slope vegetation using mud produces turbidity in rain, acid mine drainage by surface water that has passed through mud layers, contaminating water, soil and water beneath abandoned mines, and contaminating air by scattering fine particles. .

The solidification method mixes and solidifies cement and fly ash in the tailings / waste ore, thereby fixing contaminants such as heavy metals and fine particles contained in the tailings / waste ore in a physically and chemically stable state.

The tailings / waste ore solidified by the solidification method is also reused for construction and civil engineering materials and landfill cover, but it causes high costs due to low consumption.

In addition, although a large amount of turbidity generated in the soil of the incision surface is prevented, the vegetation was carried out for stabilization of the inclined surface, but due to the excellent tilting phenomenon, the scour action occurs greatly on the vegetation slope. Therefore, the vegetation state becomes poor.

The present invention is to provide a slope stabilization structure and a rust frame to prevent contamination by the tailings / waste ore or soil of the cut surface of the waste mine at low cost.

The present invention treats tailings / waste ore or soil of waste mines in a natural manner to provide slope stabilization structures and rust frameworks that prevent heavy metal elution, acid mine drainage and turbidity in the rain.

In another aspect, the present invention is to provide a slope stabilization structure and rust frame to prevent water pollution, soil pollution and water pollution, and to prevent air pollution due to the scattering of fine particles.

An inclined surface stabilization structure according to an embodiment of the present invention includes an inclined surface of any one of tailings / waste ore and soil of an abandoned mine, and a plurality of green frameworks that are installed to be coupled to each other in an inclined direction on the inclined surface. Each of the rusters includes a pair of side walls spaced at predetermined intervals, a front wall integrally connecting the side walls at one end of the side walls, and the other of the side walls at an opposite side of the front wall. And a connection bar integrally connecting the side walls from the side end, and the space set by the side wall, the front wall and the connection bar may be filled with soil to provide a vegetation space on the inclined surface.

The front wall may form a through hole to connect the space formed together with the side walls to the neighboring rusted frame or the outside to drain.

The side walls each include a low end and a high end formed in a stepped structure, and the front wall is formed at the same height as the bottom end of the side wall, and the pair of high ends is above the low end filled with the soil. A drainage passage can be formed.

The connection bar may be formed at a position lower than the high end, and may be coupled to the lower end of the neighboring green frame.

Rust frame according to an embodiment of the present invention may include an order plate formed integrally with the walls forming the space.

According to an embodiment of the present invention, a rusted frame includes a pair of side walls spaced at predetermined intervals, a front wall integrally connecting the side walls at one end of the side walls, and the opposite side of the front wall. It may comprise a connecting bar for integrally connecting the side walls above the other end of the side walls.

Rust frame according to an embodiment of the present invention, the connecting bar is spaced apart at intervals in the vertical direction, may further include an order plate for closing one side by connecting the bottom of the side walls and the bottom of the front wall. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like elements throughout the specification.

1 is a longitudinal sectional view of an inclined surface stabilization structure applied to an inclined surface of a tailings / waste ore of a closed mine according to a first embodiment of the present invention.

Referring to FIG. 1, the inclined surface stabilization structure according to the first embodiment is continuously coupled along an inclined surface (Y axis direction) on an inclined surface IP formed of the tailings / waste ore 100 of the closed mine and an inclined surface IP. It includes a plurality of green frame 200 is installed.

One embodiment of the present invention may be applied to the inclined surface (IP) formed by the tailings / waste ore 100 of the waste mine or the inclined surface formed by soil, in this embodiment stabilization of the inclined surface (IP) of the tailings / waste ore (100) First, the structure to be described will be described.

The tailings / waste ore 100 is piled around the abandoned mine and thus has an angle of repose and forms an inclined surface IP. The tailings / waste ore 100 contains trace minerals that are of no economic value and also contains various heavy metal components (eg, Fe, Al, Mn, As, etc.).

Rust frame 200 is formed on the inclined surface (IP) continuously coupled and installed along the inclined direction (Y-axis direction) is formed to cover the inclined surface (IP) of the tailings / waste ore (100). At this time, the plurality of green frame 200 is provided along the inclined direction (Y-axis direction) on the inclined surface (IP) to form a line set 300 of one unit.

In addition, the line sets 300 of one unit formed of the rust frames 200 are disposed along the direction (X-axis direction) crossing the inclination direction (Y-axis direction) on the inclined surface IP. In addition, the plurality of line sets 300 are connected by connecting neighboring rusted frameworks 200 to each other with a connecting member (not shown) in an intersecting direction (X-axis direction), thereby forming a vegetation space over the entire inclined surface IP. Can be formed.

Therefore, the inclined surface IP having a predetermined area is covered with a plurality of green frameworks 200, line sets 300 formed of the green frameworks 200, and further, a plurality of line sets 300. The space is completed. The green frame 200 stabilizes the structure of the inclined surface IP while providing a vegetation space on the inclined surface IP of the tailings / waste ore 100 and also improves the aesthetics of the inclined surface IP.

Rust frame 200 may be provided on the inclined surface (IP) to be filled with soil 400 to provide a vegetation space, it may also provide a vegetation space by accommodating a rust green bag (not shown). For convenience, the first embodiment will be described with an example of filling the space S partitioned with the rust frame 200 with the soil 400. Filling the rust frame 200 with the soil 400, it is possible to implement pollution prevention by the tailings / waste ore 100 while reducing the cost, compared to the case of using the rust bag.

The slope stabilization structure uses the rust mold 200 and the soil 400, or when using the rust mold 200 and the rust bag, both recover the slope (IP) of the tailings / waste ore 100 naturally.

The rusted frame 200 used for the slope stabilization structure may be formed in various structures, which will be described below with an example.

FIG. 2 is a perspective view of a rusty frame according to a first embodiment applied to FIG. 1, and FIG. 3 is a side view of FIG.

2 and 3, the green frame 200 partitions a space (S) having a height in a direction perpendicular to the inclined surface IP (Z-axis direction) to provide a vegetation space on the inclined surface IP. Rust frame 200 includes a plurality of walls forming a space, that is to say as an example, Rust frame 200 is a pair of side walls 201, front wall 202 and the connecting bar 203. ).

The pair of side walls 201 are spaced apart at predetermined intervals to define the width direction (X-axis direction) size of the space S formed by the rust frame 200, and the distance between the side walls 201 is necessary. The design can be changed accordingly. When installing the green frame 200 on the inclined surface IP, the side walls 201 are arranged in parallel with the inclined direction (Y).

The front wall 202 integrally connects the side walls 201 at one end of the side walls 201. The front wall 202 defines the front range of the space S formed by the rust frame 200, and also defines the spacing of the side walls 201.

The connecting bar 203 integrally connects the side walls 201 above the other end of the side walls 201 on the opposite side of the front wall 202. The connection bar 203 defines a rear range of the space S formed by the rust frame 200, and also defines a distance between the side walls 201.

Therefore, the connecting bar 203 and the front wall 202 have the same size in the crossing direction (X-axis direction). In addition, the front wall 202 blocks the entire front surface of the rusted frame 200, but the connection bar 203 is formed only in the rear portion of the rusted frame 200. Therefore, the space S formed by the rust frame 200 forms a structure that is mostly opened at the connection bar 203 side, that is, above the inclined surface IP. The part which is open above the inclined surface IP is cut off in front by the front wall 202 of the other green frame 200 connected upward.

In this way, the rust frame 200 is a vegetation on the slope (IP) by filling the soil 400, the space (S) is generally set by the side walls 201, the front wall 202 and the connecting bar 203 To provide space.

In addition, the green frame 200 may further include an order plate 204. The order plate 204 is spaced apart from the connecting bar 203 along the orthogonal direction (Z-axis direction) orthogonal to the plane (XY plane) of the inclined surface IP. That is, the order plate 204 connects the lower end of the side walls 201 and the lower end of the front wall 202 to form a bottom surface of the rusted frame 200 that is isolated from the inclined surface IP.

The order plate 204 is further limited by closing the lower side of the space S formed by the green frame 200, and is installed in close contact with the inclined surface IP when the green frame 200 is installed on the inclined surface IP. The order plate 204 thus blocks water from the inclined surface IP, for example, the elution of heavy metals from the tailings / waste ore 100 and the acidic acid drainage.

When the green frame 200 is installed on the inclined surface IP, the front wall 202 is positioned below the inclined direction (Y-axis direction). Therefore, the surface water formed due to rainwater flowing into the rusted frame 200 is guided down the inclined direction (Y-axis direction) through the inclined order plate 204 and collected toward the front wall 202.

The front wall 202 forms a through hole 205 in order to drain the surface water flowing into the space S partitioned by the rust frame 200 in the inclined direction (Y-axis direction). One or more through holes 205 may be formed in the front wall 202 between the side walls 201.

When installing the inclined surface (IP) by connecting the green frame 200, the through hole 205 is the surface water from the upper green frame 200 in the inclined direction (Y-axis direction) to the lower green frame 200 It is sent down sequentially, and discharged out of the inclined surface (IP) to the outside through the rusting frame 200 of the lowermost. Therefore, rainwater and surface water collect on the inclined surface IP and the green frame 200 in the cross direction (the X-axis direction), that is, it is possible to partially prevent the phenomenon.

The green frame 200 forms side walls 201 in a staircase structure in order to more effectively prevent rain and surface water from falling. That is, the side walls 201 include a low end 206 formed lower and a high end 207 formed higher than the low end 206. The bottom end 206 is formed in a range from the order plate 204 to the front wall 202 upper end on the front wall 202 side, and the high end 207 is the front wall 202 on the connecting bar 203 side. In a portion corresponding to the upper end side of the) is formed in a range from the top of the rusted frame 200. That is, the sum of the range of the low end 206 and the high end 207 is equal to the height of the entire green frame 200.

Therefore, when installing the rust frame 200 on the inclined surface (IP), in the rust frame 200 of one unit, the high end 207 is located above the inclination direction (Y-axis direction), the low end 206 is inclined It can be located below the direction (Y-axis direction) and vice versa, and when connecting the plurality of green frame 200, the neighboring high end 207 continues in a straight line.

In this state, the space S formed by the rust frame 200 is filled with soil 400, and the soil 400 is filled to the uppermost end of the low end 206, that is, the boundary point with the high end 207. Accordingly, the pair of high ends 207 form a drain passage EP between each other on the soil 400.

The drain passage EP is connected below the inclined direction (Y-axis direction) along the line set 300 connected in the inclined direction (Y-axis direction) to discharge rainwater and surface water. Therefore, the drainage passage EP reduces the cost by eliminating the formation of a separate drainage hole, and blocks the inflow of rainwater and surface water between neighboring line sets 300 in the orthogonal direction (X-axis direction), thereby further reducing the pulling out phenomenon. Can be effectively prevented.

The front wall 202 is formed at the same height as the bottom end 206 so as not to disturb the drainage of the drain passage EP and the surface water formed by the upper end 206 and between the high ends 207. Therefore, the drain passage EP is continuously formed between the adjacent green box 200 in the inclined direction (Y-axis direction). The front wall 202 may also be formed at a height lower than the bottom end 206 (not shown).

In forming the line set 300 by connecting the plurality of green frame 200 in the inclined direction (Y-axis direction), it is necessary to strengthen the fastening force with respect to the inclined direction (Y-axis direction) of the adjacent green frame 200. There is. To this end, the connection bar 203 is formed at a position lower than the high end 207, and is coupled to the bottom end 206 of the neighboring green frame 200.

1, the front wall 202 of the upper green frame 20 between the connecting bar 203 of the lower green frame 200 and the order plate 204 with respect to the inclined direction (Y-axis direction). And the low end 206 is inserted. Therefore, the two neighboring green frame 200 forms a solid connection and coupling state with each other.

4 is a bottom view of FIG. 2. Referring to FIG. 4, the rusted mold 200 may be formed of various materials, and may be formed of a synthetic resin material having a hollow structure by injection molding.

At this time, at least one of the side walls 201, the connection bar 203 and the front wall 202 may further include a reinforcing rib 500 for reinforcing strength inside the hollow structure.

For example, the reinforcing rib 500 includes first and second reinforcing ribs 501 and 502 formed on the side wall 201 and the connection bar 203 respectively, which are opened toward the inclined surface IP, and the inclined surface IP. A third reinforcing rib 503 formed in the front wall 202 that opens in the opposite direction of the &lt; RTI ID = 0.0 &gt;

Therefore, for example, when the rusted frame 200 is manufactured by an injection process, the rusted surface 200 is installed on the inclined surface IP, and the first and second reinforcement ribs 501 and 502 are inclined surface IP. It is formed in the side wall 201 and the connecting bar 203 which is closed on the opposite side (upward) and opens toward the inclined surface IP (downward), and the third reinforcement rib 503 is on the inclined surface IP side (downward) It is formed in the front wall 202 which is closed and opens in a direction away from the inclined surface IP, i.e., in a direction opposite to the inclined surface IP (upward).

That is, in order to simplify the mold used in the injection process, the first and second reinforcement ribs 501 and 502 and the third reinforcement rib 503 are formed in the inside which are opened in opposite directions to each other. When the rusted frame 200 does not include the order plate 204, the mold of the portion for forming the first and second reinforcement ribs 501 and 502 is simply compared with the case where the order plate 204 is included. do. The third reinforcement rib 503 reinforces the front wall 202 while allowing drainage action by the through hole 205 formed in the front wall 202. That is, since the front wall 202 is opened upward with respect to the inclined surface IP and the third reinforcing rib 503 is formed in the front wall 202, the through hole 205 can stably drain.

Rust frame 200 forms the mounting holes 208 in the orthogonal direction (Z-axis direction) at both ends of the side walls (201). Referring to FIG. 1, the installation tool 208 allows the installation member 209 to be fixed to the inclined surface IP by putting the installation member 209 on the inclined surface IP.

For example, the installation tool 208 is formed in the four corners of the rust frame 200, and is formed in the high end part 207 and the low end part 206. As shown in FIG. Therefore, when the rusting frame 200 is continuously installed and installed, the mounting hole 208 of one high end 207 and the mounting hole 208 of the other low end 206 are in a straight line in the orthogonal direction (Z-axis direction). Is placed.

Therefore, one mounting member 209 has a pair of mounting holes 208 formed in each of the pair of high end portions 207 and the front end portion 206 arranged in a straight line along the orthogonal direction (Z-axis direction). Penetrates integrally;

When the rusted frame according to the first embodiment of the present invention is installed and the discharge state of the pollutant is not compared, it is shown in Table 1.

Unit: ppm matter Ph Fe Mg Al Mn Zn CD Pb Fine construction 2.9 234.99 303.87 42.63 19.78 3.98 0.01 0.05 Construction 6.8 0 7.29 0.04 0.16 0.02 0 0

In the first embodiment, the order frame 204 is provided in the rusted frame 200 to block rainwater and surface water from flowing from the inclined surface IP, thereby blocking the binding of water and oxygen, and thus, in the tailings / waste ore of the abandoned mine. It can be seen that the concentration of pollutants caused by the leaching of heavy metals and acid mine drainage is drastically reduced.

5 is a longitudinal cross-sectional view of the rusted frame according to the second embodiment of the present invention and the inclined surface stabilization structure in which the same is applied to the inclined surface of the soil.

In the second embodiment, the description of the same parts will be omitted, and different parts will be described in comparison with the first embodiment.

Referring to Fig. 5, the green mold 600 of the second embodiment does not include the order plate 204 when compared with the green mold 200 of the first embodiment. That is, the rusted frame 600 forms a structure penetrated in the orthogonal direction (Z-axis direction) with respect to the inclined surface IP.

Therefore, the rusted mold 600 of the second embodiment is installed and used on the inclined surface IP of the earth and sand 700 which does not occur by the elution of heavy metals and acid mine drainage.

When the rusted mold 600 of the second embodiment is installed on the inclined surface IP, and the vegetation is filled with the soil 400 in the set space S of the rusted mold 600, the root of the plant is made through the soil 400. As it enters the soil 700, the stabilization structure of the inclined surface IP becomes more robust. In the rusted mold 600 of the second embodiment, it may be more effective to use soil than when rusted white is used.

In the case of using the rusted frame 600 of the second embodiment, the rainwater and surface water penetrate into the inclined surface IP through some space (S), the rest is drainage passage (EP) formed between the high end (207) Is discharged through.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. Naturally, it belongs to the scope of the invention.
