Description

Method of Constructing Bank Walls with Recovering Natural Environment

The present invention relates to a method of constructing a slope, and more particularly, to a method for constructing a natural environment restoration type slope that can reproduce a slope such as a river or riverbank in a manner suitable for the natural environment.

Generally, when constructing banks of rivers, rivers, or rivers, or constructing cutouts, the soil of the river is used as it is, and it is covered with cement blocks on it, or by using concrete.

However, the construction method by the protection block or concrete formed by cement block does not provide any environment for plants to grow after the construction of the embankment, etc., which is incompatible with the surrounding environment and has the disadvantage of destroying the ecosystem. have.

In order to improve the shortcomings of the concrete construction method is the construction method of the slope or shaft wall using the Gabion gabion. Gabion gabions are hexagonal or rectangular iron mesh panels that are made of polyhedrons and are filled with rubble and other fillers. Wire mesh Gabion is filled with natural stone, pebble, rubble, etc. inside Gabion woven into a wire mesh, and then it is cut into road cuts, embankments to prevent erosion, bridges to prevent erosion from pier, defense walls of breakwater, retaining walls and shaft walls of slopes, etc. It is widely used for a purpose.

The conventional method of building a slope using a Gabion gabion is to tear down the incision or the slope to a considerable extent, install a base of Gabion mattress in the torn down position and fill the interior of the Gabion Mattress with fillers such as crushed stone, rubble and waste-rock. Forming a wire mesh cover thereon and finishing; Or filling soil directly on the stone layer, or laying a support member capable of plant growth on the stone layer, and filling the soil thereon, forming a wire mesh cover, and finally planting the plant or tree thereon. It consists of.

However, the method of constructing the slope using the Gabion gabion was required to use a filler such as crushed stone, rubble, or waste-rock in the Gabion gabion. First, in order to obtain the filler, the crushed rock or crushed stone was removed there. Because it has to be collected, it is rather environmentally damaging. Secondly, if the supply of crushed stone or waste-rock is not smooth, it will cause a delay in the work process and increase the cost of work. When it grows, the filling material will rather hinder the growth of the roots, it can not help not to illustrate that negatively affects the growth and growth of the plant.

In addition, the conventional construction method of the slope using Gabion, when the plant meets the heavy rain or enters the rainy season in the state that the plants do not properly stick or grow after the construction, the water flows rapidly to the river, etc., the construction is completed, the flow rate is faster, As a result, the wire mesh structure is peeled off from the bottom of the river due to the scour phenomenon of the bottom of the river, and a phenomenon in which the inclined surface constructed therewith is lost.

As described above, the conventional method of constructing the slope using Gabion gabion has the disadvantages of destroying the environment in order to obtain the filling material, and has the disadvantage of restricting the conditions under which the plant roots can grow by the filling material. It is a situation that has a disadvantage that does not cope efficiently with suddenly blown water.

Accordingly, an object of the present invention is to provide a method of constructing an inclined surface that does not use a filler in the process of constructing an inclined surface.

In addition, the present invention is the construction method of the inclined surface that can maintain the construction state without being affected by the structure of the already installed wire mesh even by the rapid water flow rate even if the heavy rain occurs suddenly after the construction of the construction The purpose is to provide.

The present invention relates to a method of constructing inclined surfaces that can reproduce inclined surfaces such as rivers and riverside banks in a manner suitable for the natural environment.

Method of constructing the inclined surface according to the present invention comprises the steps of selecting the inclined surface of the area to be constructed and the step of stopping the surface of the inclined surface to form a soil to grow the plant; A ditch forming step of digging the bottom surface of the stream connected to the lowermost end of the inclined surface with a predetermined depth and width and forming a ditch in the longitudinal direction of the stream; A first wire mesh arrangement step of placing the wire mesh on the inclined surface formed in the stopping step; A second wire mesh arrangement step of disposing a wire mesh or a wire mesh mattress in a ditch of the river, filling a filling material therein, and then fastening a cover; A finishing step of planting and finishing plants through the empty spaces between the wire meshes on the inclined surfaces; It includes.

In the present invention, the filling material used in the second wire mesh arrangement step is to use waste construction materials such as concrete blocks or revetment blocks, which are installed on the inclined surface, waste concrete or waste revetment blocks, or using gravel soil at the bottom of the river. It is characterized by.

Hereinafter, the present invention will be described in more detail.

The present invention includes the step of selecting the inclined surface of the area to be constructed, stopping the surface and stopping the inclined surface to form soil in which the plant can grow.

The present invention selects the inclined surface of the area to be constructed, and rolls the surface of the inclined surface. Areas to be constructed include large rivers, small rivers, or banks or banks of rivers or streams. The inclined surface of the selected area can be divided into the case of natural formation and the case of artificially formed slope or concrete block on the slope. If the inclined surface is constructed by a concrete block or the like, it is important to remove such an artificial construction because the plant cannot be a foundation for growth.

The present invention is to remove the surface of the slope of the area to be constructed, to secure the soil in which plants can grow. The soil refers to the internal soil of the embankment or bank that basically forms the slope. Therefore, when a concrete block or the like is constructed, it is necessary to remove this and continue digging until the original soil is exposed.

In the present invention, when the inner soil of the inclined surface is exposed, it is important to stop it evenly, and to mix the inner soil so that the plants can grow. This is to mix internal soil, which has been poorly breathed with the air by concrete blocks or revetment blocks, so that the internal soil can come into contact with air.

In addition, the present invention can be formed in multiple stages according to the shape of the inclined surface, it is also possible to form different inclination angle of each stage. This is to respond appropriately according to the situation of the workplace and to be able to harmonize with the surrounding environment.

The present invention includes a step of forming a ditch of a river to dig a bottom surface of a river connected to the lowermost end of the slope.

The present invention forms the inclined surface, then digs the bottom surface of the river connected to it and forms a trench along the inclined surface in the longitudinal direction of the river.

In the present invention, the trench is formed not in the entire bottom surface of the river, but in a portion connected to the river below the inclined surface. This is to securely hold the first wire mesh installed on the inclined surface at the bottom portion of the river, and to use it as a means for preventing the first wire mesh from being lost by the scour of the river. It becomes more specific in relation to the second wire mesh.

In the present invention, the trench is preferably dug downward with respect to the bottom surface, and it is preferable to dug along the slope of the river in the longitudinal direction of the stream. The depth of the trench can vary depending on the scour of the river or river in which the work is being performed. In the case of severe scour, a depth of 1 meter to 3 meters is preferred, while in the case of moderate scour, a depth of 10 centimeters to 50 centimeters Is preferred.

The present invention includes a first wire mesh arrangement step of placing the wire mesh on the inclined surface formed in the stop step.

In the present invention, the first wire mesh is provided directly on the inclined surface whose surface is arranged. In the first wire mesh, it is preferable that the horizontal wire and the vertical wire cross or twist each other to form a quadrangular mesh, a pentagonal mesh or a hexagonal mesh.

In the present invention, the first wire mesh is not only installed on the inclined surface, but also extended to the lower side of the river, it is characterized in that it is also installed in the ditch. This means that the first wire mesh forms a mutual coupling relationship with the second wire mesh below, which will be described later.

In the present invention, the first wire mesh prevents the plants to be grown by the wires forming the meshes from being lost by heavy rain or flooded river water, whereas the empty spaces formed between the meshes This allows land and plants to be exposed to atmospheric air and sun sunshine.

In the present invention, the first wire mesh is preferably fixed to the inclined surface because it is fixed by the fixing means. The fixing means is preferably a pile or a fastener, and more preferably an anchor member in which two nails are deviated from each other. The fixing means performs the function of fixing the first wire mesh to the inclined surface, but in addition, if the inclined surface is wide, it can simultaneously perform a function as an identifier for distinguishing the inclined surface and the inclined surface of the lower side. The function of the identifier means that when planting a plant, aquatic plants or similar species inhabiting the bottom of the stream are planted on the side of the bottom of the slope and adjacent to the bottom of the stream, and in the middle or the top of the stream. It means that it is used as a marker for planting the kinds of plants commonly found in the plant or for selecting the kinds of plants selected for the improvement of the surrounding environment. Since the first wire mesh is provided on the inclined surface, when the inclined surface is formed in multiple stages, it is preferable that the first wire mesh is arranged and provided in multiple stages accordingly.

The present invention includes a second wire mesh arrangement step of disposing a wire mesh or a wire mesh mattress in the ditch of the river, filling a filling material therein, and then fastening a cover.

In the present invention, the second wire mesh arrangement step is performed to prevent the first wire mesh installed on the inclined surface from being lost by the scour phenomenon of the bottom of the river. Typically, the first wire mesh on the inclined surface is fixed to the inclined surface by a pile or anchoring. However, when a heavy rain occurs or the water blows rapidly during the rainy season, the bottom surface is scoured due to the severe flow rate, and the end of the first wire mesh is exposed to the water of the river in the scoured portion. At this time, the exposed portion of the first wire mesh is covered with rubbish such as grass, wood, vinyl, etc., which has been pushed down by water, and they collect other rubbish again and resist the flow rate of water. However, as the flow rate of water increases, the blown water pushes them further down, and the rubble and the end of the first wire mesh that are no longer able to withstand the flow rate of the blown water are pushed down again. As a result, the first wire mesh fixed to the inclined surface does not endure the flow velocity of the blown water, and is peeled off from the end upwards. In the present invention, the second wire mesh is to prevent this phenomenon, and the reason will be easily found below.

In the present invention, it is preferable that the second wire mesh also crosses or twists each other to form a quadrangular mesh, a pentagonal mesh or a hexagonal mesh, and these are formed into a mattress or box. Pre-cut and processed Gabion Boxes or Gabion Mattresses can be used. Since the second wire mesh is not directly related to the planting of plants, there is no inevitable reason for using the wire mesh, but it is a preferable raw material in view of efficient work performance and material simplicity.

In the present invention, the second wire mesh is disposed inside the trench formed on the bottom surface of the river. Preferably, the second wire mesh is disposed to overlap with the first wire mesh extending from the inclined surface, and more specifically, the first wire mesh is disposed below and the second wire mesh is disposed above. . However, even when arranged in reverse, the filling material to be filled in the inside of the second wire mesh presses them all together, and therefore the arrangement structure is not particularly limited. On the other hand, since the groove is open at the top and forms a U-shaped wall surface, when the second wire mesh is disposed inside the groove, the second wire mesh also forms a U-shaped hollow space therein.

In addition, in the present invention, the second wire mesh may be formed to extend to the first wire mesh. In this case, it is preferable that the said 1st wire mesh continues to extend and extends including all the U-shaped interior of the said groove, and extends even to the part of a lid | cover.

In the present invention, the U-shaped hollow space of the second wire mesh is filled with a piece of concrete block, raft block or waste concrete pieces as a filler. The pieces of the concrete block or the revetment block can be used as it is, after removing the concrete block or revetment block installed on the conventional inclined surface. When the conventional concrete block is removed, the waste construction equipment should be disposed of as a separate procedure and cost. The present invention has the advantage that the waste construction equipment can be used as it is in the construction method of the present invention. . If the concrete block or the bank block can not be utilized, it is enough to use the gravel stones of the surroundings or rivers, and it is not necessary to use a separate crushed stone. This is because the filling material of the present invention is located below the bottom of the river and is not exposed to the outside, so it is not necessary to consider the aesthetics of the filling material at all, and it is sufficient to simply press the second wire mesh (or the first wire mesh). to be.

In the present invention, the second wire mesh is filled with a filling material therein, the upper portion is covered with a cover wire mesh and fastened thereto. Fastening of the cover wire mesh can be carried out in a conventional manner. In the present invention, the covering of the cover is to prevent the filling material filled therein from being lost out. The top of the cover is preferably covered with dirt or gravel stones or a mixture thereof at the bottom of the river again. In this case, the bottom of the stream has a shape similar to that of a conventional bottom surface, and water flows over it again.

The present invention includes a finishing step of planting plants on the inclined surface through the empty space between the first wire mesh and performing the finishing work.

In the present invention, the plant may be selected varieties that harmonize with the surrounding natural environment, or plant varieties may be selected in consideration of the newly created natural environment. In addition, the above-mentioned plants may be used in the form of seeding and germinating, or may be used by planting on the inclined surface in a certain growth state. If you use the seed form, you will need to spray it again, but if you use a plant that has already grown, you do not need to do so. In addition, the said plant may select and use a single variety, and may select and use 2 or more types. When two or more species are used, it is preferable to select a kind suitable for aquatic plants at the part near the bottom of the stream, and to select a different plant type at the part far from the bottom of the stream.

More preferably, the vegetation nonwoven fabric is laid on the surface of the inclined surface after the inclined surface stopping step and the first wire mesh is installed thereon.

In the present invention, the vegetation nonwoven fabric is preferably made of a vegetable material that can be decomposed by soil microorganisms to become a nutrient source of the plant. The vegetation nonwoven fabric is primarily intended to prevent the loss of the inclined surface of the interior by the rainwater that has soaked when heavy rain occurs after the work is completed. When plants planted in the liver grow down to the root, the secondary purpose is to be a nutrient source of the plants, rather than to prevent the loss of the slope. From this point of view, the vegetation nonwoven fabric is preferably a product using straw or palm bark.

Since the present invention basically does not fill the inside of the wire mesh while installing the wire mesh inside the inclined surface, when the plant is planted, the roots are not disturbed by the filling material until reaching the inclined surface, thereby It leads to more positive and desirable results on the rooting and growth of plants.

In addition, the present invention does not need to fill the filling material, there is no need to purchase the filling material for construction, and thus there is an advantage that can be inclined at low cost.

In addition, in the present invention, when the conventional concrete block is rolled out and a new inclined surface is newly constructed, waste construction materials such as the first concrete block removed can be used as it is, and on the other hand, the environmental conservation can be further improved. The advantage is that the construction cost can be further reduced.

Although the construction method of the natural restoring slope according to the present invention has been described in detail above, this is only for describing the most preferred embodiment of the present invention, and the present invention is not limited thereto, and according to the appended claims Range is determined and defined.

In addition, anyone of ordinary skill in the art will be able to make various modifications and imitations by the description of the specification of the present invention, but it will be apparent that this is also outside the scope of the present invention.
