Description

Supporter for naturally protecting an inclined plane}

The present invention relates to a natural shore revetment support, and more particularly to a revetment support for protecting the slope of the river using natural stones.

In recent years, the river environment has changed significantly as land use in river basins increases and urbanization progresses. In particular, urban rivers with high land-use densities around rivers have changed the river environment due to the maintenance of reservoirs and reservoirs, the linear maintenance of rivers, and the construction of river banks. Moreover, as the reservoirs were strengthened, the curve linearity of the natural rivers changed into straight lines, and the slopes of the reservoirs became concrete.

As mentioned above, a river structure with a moderately varied slope of the river is shown in cross section in FIG. 1A. The cross section of the river having a gentle slope is largely divided into a levee 1, a coriander site 2, and a handmade portion 3 having a gentle slope. At present, the embankment 1, the coriander site 2, and the handmade part 3 were artificially concreted according to urban planning.

On the other hand, Figure 1b is a cross-sectional view showing a river structure having a steep slope, as shown, to prevent the erosion of the steep slope of the river, the entire basin of the river is concrete. That is, the concrete foundation 5 was provided in the lower part of the river, and the concrete block 6 was laminated | stacked on it.

By the way, the maintenance of the river using only concrete as shown in Figure 1a and 1b has a problem that the plant growth is very difficult. As a result, most of the current river basins have destroyed river ecosystems, and have become bleak environments where only concrete structures are visible with few plants.

In addition, the existing river maintenance using concrete was hardly considered for the river ecosystem, but mainly large-scale civil works for the purpose of dimension and completion, and the natural natural function of the river was almost destroyed. As a result, not only the water quality of the river is polluted, but also the number and types of fish and algae inhabiting the river plants and rivers are drastically reduced.

In particular, the slopes of rivers are very high in ecological productivity and biodiversity, and in natural river ecosystems, they are the transition zones that form the boundary between underwater and land. If the transition zone is concreted, the linkage between the underwater and terrestrial ecosystems will be broken, so that the flora and fauna living in the transition zone will be almost extinct, and secondly, it will have a great negative effect on the entire river ecosystem.

In addition, the bottom of the concrete and the slopes of the river physically blocks the river water infiltrates into the soil layer, the natural riverside vegetation is dried, the shade provided by the riverside vegetation disappears. As a result, the water temperature changes rapidly, losing its function as a habitat and spawning place for aquatic plants and fish, and destroying the habitat of algae that feed around the reservoir and hide in vegetation bushes.

Therefore, in recent years, as interest in the river environment increases, an attempt has been made to restore and restore an ecologically damaged river environment. One of such attempts is a lakeside support using the stone shown in FIG.

The revetment supporter shown in FIG. 2 binds the stones to a support mesh 4 made of metal. Unlike the concrete, the revetment support of such a structure has the advantage of allowing water to pass through each stone.

However, in order to manufacture the conventional lake eye support shown in Fig. 2, since it is necessary to bind a plurality of stones to the inside of the metal mesh, it is very difficult to manufacture. In particular, despite the sufficient amount of stone in the river basin, it is difficult to produce the conventional shore banks at the site of the river basin. There was also.

The object of the present invention is to provide a lake shore construction using natural stones in the river basin, so that it can be manufactured on site and the construction cost is low.

Another object of the present invention is to provide a habitat for aquatic flora and fauna by using natural stones, and not only destroy the river ecosystem, but also recover the destroyed ecosystem.

In order to achieve the above object, the raft support according to the present invention is made of the following configuration.

First, the shoreline support used in the case of the river basin with a gentle slope and a sediment is composed of a structure in which natural stones in the field are attached to the support network using an adhesive.

On the other hand, the shore support is used when the river basin is a steep slope is made of a structure in which one end of the wire is connected to the natural stone, the fixing plate is fixed to the steep slope on the other end of the wire.

According to the configuration of the present invention described above, by attaching enough natural stone to the support network on the site or connecting a fixture, and by placing this natural stone in the river basin, it is possible to construct a lake in the field at a low cost. In addition, since the flow of river water is freely made between each natural stone, a habitat of aquatic flora and fauna is provided between each natural stone to preserve or restore the river ecosystem.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Example 1

Figure 3a is a perspective view showing a revetment support according to a first embodiment of the present invention, Figure 3b is a view showing a method of attaching natural stone to the support network of the revetment support, Figure 4 is a gentle inclination according to the first embodiment It is sectional drawing which showed the state in which the shore support support was installed in the river basin which has

First, the raft support shown in Fig. 3a is applied to a river inclined surface consisting of a dike, a coriander site, and a gentle slope of the handmade portion. The revetment support has a structure in which natural stones 14 of various shapes are bonded onto the support network 10. As shown in FIG. 3B, the adhesive 12 is applied to the flat portion of the natural stone 14, and the natural stone 14 is bonded onto the support net 10 using the adhesive 12. As the adhesive 12, it is preferable to use a special epoxy mortar bond having semi-permanent durability.

Here, the material of the support net 10 is a plated iron wire of zinc / aluminum alloy in the first embodiment, and has a durability of about 35 years in water or soil and about 40 years in a good environment such as in the air. The reason why the zinc / aluminum alloy is used as the material of the support net 10 is because of the durability period that the wire of this material has in water or in the soil. In other words, since the support net 10 is corroded after about 35 years in air, especially in water, the strength is lowered, and thus the support net 10 loses the function of supporting the natural stone 14 adhered to the upper portion. Therefore, the support network 10 until a period in which the roots of the waterside plants planted between the natural stones 14 to be described later will be sufficiently grown between the natural stones 14 or a sedimentary layer may be formed to support each natural stone 14. ) Must have the function to support natural stone (14) without corrosion. Since the roots of the waterside plants are sufficiently grown or the gravel deposits in the river are formed for about 30 years, zinc / aluminum alloys having a durability of 35 years or more in water are selected as the material of the support net 10. Therefore, of course, another material having a durability of about 35 years or more in water can be selected as the material of the support net 10.

On the other hand, natural stone 14, as shown in Figure 3a, is not a regular shape but made of various shapes that are not regular. This is because the stones in the river basin are used as natural stones 14. Using the natural stone 14 of the river basin to produce a lake shore support by a simple bonding method as described above, it is possible to easily produce a lake shore support in the river basin site.

As shown in Fig. 4, the rafting support prepared as described above is installed on the cilantro site 2 and the gentle slope 3. At this time, since the natural stone 14 is firmly adhered to the support network 10, there is no fear that the natural stone 14 will be lost due to river flow.

When the cover is applied to the shore support, the soil is closely filled between each natural stone (14). Planting waterside plants in the soil causes the roots of the waterside plants to grow into the river bed 16 through each natural stone 14 over several years to several decades. In addition, the roots of each waterside plant grow while surrounding each natural stone 14 and are also connected to the roots of other waterside plants, whereby the natural stone 14 is firmly fixed. At this time, even if the support network 10 is corroded and loses the function of supporting the natural stone 14, the natural stone 14 can be maintained as it is disposed on the river slope. In addition, when the support network 10 is located in the water, the gravel on the bottom of the river is deposited, and the aquatic plants inhabit this sedimentary layer, so that the natural stone 14 is firmly supported as described above.

On the other hand, since the support net 10 has some ductility, it can be easily installed in the river bottom which has a complicated shape. Since the support net 10 can be manufactured in any size, it can also install several pieces with a different shape in a mosaic form according to river conditions. In the case of underwater construction, it can be easily constructed using a crane or the like. The size of the support network 10 and the size of the unit grid are determined by the river environment in which the banking industry is constructed, and the adhesive 12 is also determined by the weight of the natural stone 14 and the flow velocity of the river.

As described above, according to the rafting method according to the first embodiment, by using the natural stones 14 of various shapes irregularly enough in the river basin, the entry and exit of water between the natural stones 14 is very similar to the actual natural. Done. Therefore, the natural stone 14 according to the first embodiment naturally provides a reproductive space as a habitat and spawning place for underwater plants and fish. It also provides a habitat for algae hiding in waterside plants. In addition, by covering between the natural stones 14, the plant can be naturally restored early.

Example 2

Figure 5 is a perspective view showing a lanyard supporter according to a second embodiment of the present invention, Figures 6a and 6b is a view showing two methods of connecting the wire to the natural stone, Figure 7 is a lantern paper according to the second embodiment This is a cross-sectional view showing the earth installed on a steep slope of a river.

First, the rafting support shown in Figure 5 is produced. In FIG. 5, the plurality of rubble 24 is not included in the shore support, and is used when the shore support is installed on the steep slope of the river. The revetment support according to the second embodiment includes a natural stone 14 and a fixed plate 30 and a wire 28 connecting the natural stone 14 and the fixed plate 30.

One end of the wire 28 is connected to the fixed plate 30 and the other end is fixed to the natural stone 14, two ways of connecting the natural stone 14 and the wire 28 are shown in FIGS. 6A and 6B. .

First, the solution shown in FIG. 6A is to use an adhesive 12 such as a special epoxy mortar bond with the semi-permanent durability shown in Example 1. FIG. That is, the fixing hole 26 is formed in the natural stone 14 and the adhesive 12 is filled. When the wire 28 is inserted into the fixing hole 26 filled with the adhesive 12, the wire 28 and the natural stone 14 are firmly connected.

On the other hand, the solution shown in Figure 6b is to use the anchor (34). First, the anchor 34 is connected to the wire 28. Then, after the support 36 is inserted into the fixing hole 26 of the natural stone 14 by the fitting, the anchor 34 is embedded in the support 36, whereby the wire 28 and the natural stone 14 are supported. Connect it.

A revetment support is fabricated using the adopted method of the two methods described above, and as shown in FIG. 7, the revetment support is disposed on the steep slope of the river.

First, the foundation of the river bottom with concrete 20 is provided. The reason for this is to prepare for the case that the natural stone 14 of the laminated shore support is collapsed when the ground structure of the river is weak. A number of rafters are stacked on the concrete 20. At this time, the fixed plate 30 is supported in a state facing the steep slope, natural stone 14 is directed toward the center of the river. Since the stacked natural stones 14 have their own weight, it is not necessary to fix the fixed plate 30 to the steep slope.

On the other hand, the rubble 24 is also laminated between the wires 28 while laminating the shore support tool. Rubble 24 firmly supports each wire 28, thereby firmly supporting the stacked natural stone (14). Since the rubble 24 is disposed along the entire length of each wire 28, the rubble 24 as a whole has a function as a shore support wall.

Finally, the concrete 20 is poured on the rubble 24 stacked on the top. The upper concrete 20 prevents the collapse of the stacked natural stone 14.

The lamination of the natural stone 14 using the rubble 24 is stably maintained even in the flow of water. In addition, when time passes, the underwater plants propagate between each natural stone 14, the natural stone 14 can be firmly supported by the roots of the underwater plants. In addition, since deposits of river gravel are formed between the natural stones 14 disposed in the water, the stacking of the natural stones 14 is more firmly maintained.

When using the shore support support according to the second embodiment, since the water is freely passed through each natural stone 14, the flora and fauna ecosystem of the riverbanks can be preserved or restored.

As described above, according to the present invention, since the natural stone around the river is used, it is possible to directly construct the raft construction method at the river site at low cost.

In particular, by using natural stones of various forms, the flora and fauna ecosystem of the riverbanks is preserved or restored. In other words, the river slope can function as a transition zone between the water and the ground.

On the other hand, the present invention is not limited to the above-described specific preferred embodiment, any person having ordinary knowledge in the field to which the present invention belongs without departing from the gist of the present invention claimed in the claims can be variously modified. will be.
