Description

METHOD OF CONSTRUCTING LEVEE WITH ECOLOGICAL ENVIRONMENT

[Technical Field]

The present invention relates to a method of constructing a bank in an environment- friendly manner, and more particularly, to a method of constructing a bank in an environment-friendly manner, wherein a cut area or a bank of a creek, watercourse or river can be rapidly and efficiently built without using fillers such as crushed or broken stones.

[Background Art]

When constructing a cut area or constructing a bank in a creek, watercourse or river, generally the cut area or the bank may be covered with a cement block or concrete.

However, since the construction method using bank protection blocks made of cement or concrete cannot provide an environment where plants can grow after the construction, there are problems in that the construction method is not in harmony with a surrounding environment and may damage the ecosystem.

In order to solve the problems of the concrete construction method, a method of constructing an inclined surface or masonry wall using gabions has been proposed. The gabion is a steel mesh structure that fillers such as broken stones are filled in a polygonal structure formed of hexagonal or rectangular steel mesh panels. Natural stones, gravels, broken stones an the like are filled in a steel gabion formed of a steel mesh, and the steel gabion is widely used as a mattress for preventing the erosion of a bank or a cut area of a road, a bridge abutment for preventing the erosion of a bridge, a protection wall of a breakwater, a revetment or masonry wall of an inclined surface, or the like.

FIG. 1 is a schematic view illustrating a conventional method of constructing an inclined surface using gabions.

As well shown in FIG. 1, the conventional method of constructing an inclined surface using gabions comprises the steps of demolishing a cut area or an inclined surface to a significant degree; installing a base of a gabion mattress at the demolished location and forming a side member at a lateral side of the gabion mattress to define a space for containing stones; filling fillers such as crushed, broken or waste stones in the space to form a stone layer; covering a support member, which allows plants or trees to grow, on the stone layer to form a support member layer; covering surrounding soils on the support member layer to form a soil layer; covering a gabion on and coupling the gabion with the side member to form a cover layer; and then finally planting plants or trees in the soil layer.

However, the conventional method of constructing an inclined surface using gabions has least three problems as described below, since the gabion should be filled with the crushed, broken or waste stones. First, although the conventional method of constructing an inclined surface allows plants to grow in the inclined surface of a river or the like and is somewhat friendly with the environment, but it may hurt the ecological environment in other aspects. The reason is that the conventional method of constructing an inclined surface essentially requires the use of fillers such as crushed, broken or waste stones filled in the gabion. To this end, a hill or stony mountain should be demolished to acquire a large amount of fillers such as broken or waste stones. Therefore, it is inevitable that the ecological environment will be destroyed.

Second, in the conventional method of constructing an inclined surface, the relevant works are inevitably delayed or high costs should be paid for the next works in a case where the fillers such as crushed, broken or waste stones cannot be easily obtained from the surroundings. In these days, it is not easy to obtain fillers such as natural stones or large gravels from the surroundings. As a result, the crushed, broken or waste stones are generally employed, but it is also difficult to easily obtain the fillers due to the environmental aspect. Third, in the conventional method of constructing an inclined surface, fillers such as broken stones are essentially filled in the gabion to form a stone layer. However, this stone layer prevents smooth growth of roots of plants and thus rapid growth of the plants planted in the inclined surface.

Therefore, even though the conventional method of constructing an inclined surface using gabions has an environment-friendly factor, it cannot be widely employed in these days at various construction sites where inclined surfaces of rivers, cut areas or landslide prevention walls are constructed.

[Disclosure] [Technical Problem]

As described above, a conventional method of constructing an inclined surface conducted heretofore can hardly solve the adverse effects of fillers, which inevitably occur during the construction process.

Accordingly, it is an object of the present invention to provide a method of constructing an inclined surface, wherein a bank of river, a cut area or an inclined surface is constructed without using fillers such as crushed or broken stones, so that they can be restored or newly formed in an environment-friendly manner.

Further, it is another object of the present invention to provide a method of constructing an inclined surface in an environment-friendly manner, wherein a bank of a river, a cut area or an inclined surface can be rapidly and easily built without using fillers such as crushed or broken stones. [Technical Solution]

The present invention relates to a method of constructing a cut area or a bank of a creek, watercourse or river in an environment-friendly manner. According to an aspect of the present invention, there is provided a method of constructing a bank while planting plants to a cut area, an inclined surface or a bank of a creek, watercourse or river using a steel gabion, the method comprising the steps of flattening the ground of an inclined surface or a bank of a creek, watercourse or river, and smoothing a soil of the ground or mixing the soil with organic or inorganic fertilizers, and then leveling the ground; sowing seeds in the ground and covering an anti-sweeping fabric on the sowed ground to prevent the ground from being swept due to rain, to preserve subterranean heat of the ground and to help the seeds to germinate and grow; covering a steel gabion on the anti-sweeping fabric to gently press down the anti-sweeping fabric by placing the steel gabion on the anti-sweeping fabric and to keep the anti-sweeping fabric at an original position even when a local downfall or long rainy season occurs; and driving a fixing member into the ground to firmly fix the steel gabion to the ground in a state where the steel gabion is placed on the anti-sweeping fabric.

Preferably, the method of the present invention further comprises the step of covering an additional screen on the anti-sweeping fabric after the step of covering the anti-sweeping fabric on the ground, wherein the screen has smaller meshes than the steel gabion.

According to another aspect of the present invention, there is provided a method of constructing a bank while planting plants to a cut area, an inclined surface or a bank of a creek, watercourse or river using a steel gabion, the method comprising the steps of flattening the ground of an inclined surface or a bank of a creek, watercourse or river, and smoothing a soil of the ground or mixing the soil with organic or inorganic fertilizers, and then leveling the ground; spreading a seeding mattress, which is already sowed with the seeds and is held by a steel gabion, over the ground; and fixing the fixing member to the ground to fix the seed mattress to the ground. The seeding mattress may include a steel gabion having rectangular, pentagonal or hexagonal meshes; a seed mattress arranged on the steel gabion and previously sowed with seeds to be planted; and a steel gabion arranged on the seed mattress and having rectangular, pentagonal or hexagonal meshes to surround and protect the seed mattress.

Preferably, the seeding mattress further includes a screen installed between the steel gabion and the seed mattress.

According to a further aspect of the present invention, there is provided a method of constructing a bank while planting plants to a cut area, an inclined surface or a bank of a creek, watercourse or river using a steel gabion, the method comprising the steps of flattening the ground of an inclined surface or a bank of a creek, watercourse or river, and smoothing a soil of the ground or mixing the soil with organic or inorganic fertilizers, and then leveling the ground; covering a steel gabion on the ground in such a manner that the steel gabion is not brought into close contact with the ground to define a predetermined space between the steel gabion and the ground; driving a fixing member to the ground to fix the steel gabion to the ground at such a state; and spraying a planting soil mixture, which is obtained by mixing seeds and soil into a dilute water solution, onto the ground in such a manner that the sprayed planting soil mixture can be attached to the ground and can also be protected by the steel gabion. [Advantageous Effects]

As mentioned above, since the environment-friendly construction method of the present invention does not use any fillers, it can be used as a novel construction method capable of completely overcoming a primary environmental destruction problem occurring when obtaining stones.

Since the environment-friendly construction method of the present invention does not use any fillers, the difficulty in obtaining stones can have no influence on the method of the present invention. Therefore, the increase of construction costs due to the difficulty in obtaining stones can be basically prevented.

In particular, since the environment-friendly construction method of the present invention does not require any fillers such as stones, it can be applied to a vast plain or desert. Therefore, the applicability of the present invention can be greatly enhanced as compared with the conventional method.

In addition, since the environment-friendly construction method of the present invention does not use any fillers, a stone layer is not formed in the ground and the best environment where plants grow can be obtained. Therefore, the method of the present invention can be evaluated as a more environment-friendly construction method. Further, according to the environment-friendly construction method of the present invention, seeds of plants can be germinated and grown deeply in the soil, and thus, their survival rates can be improved. Furthermore, seeds flying from the outside by the wind can be germinated together, and thus, a newer plant ecosystem can be obtained.

[Best Mode]

A method of constructing an inclined surface in an environment-friendly manner according to the present invention starts with the step of smoothing or leveling the ground G of a bank, and it is then completed by sowing seeds directly in the ground G or installing to the ground G a member in which seeds are already sowed.

Hereinafter, the present invention will be explained in more detail with reference to the accompanying drawings. However, it will be apparent that the accompanying drawings merely illustrate the technical sprit of the present invention and the technical spirit of the present invention is not limited thereto.

Embodiment 1

The method of constructing a bank in an environment-friendly way according to the present invention comprises the step of forming a cut area or a bank of a creek, watercourse or river and then sowing seeds in the ground (Sl 1). Since a final purpose of the present invention is to restore a bank of a creek, watercourse or river into an environment-friendly state, the construction method of the present invention is preferably employed after the bank has been constructed. Thus, in the present invention, the bank may be already finished or under construction. In particular, in a case where an inclined surface has been constructed using conventional cement blocks or bank protection blocks, it is preferred to eliminate the cement blocks or bank protection blocks such that an underlying ground of the bank can be exposed to the outside.

In the present invention, the ground G of the bank is defined to include all the grounds of a bank of creek or watercourse, or an inclined surface or cut area thereof, unless specifically limited.

In a case where the ground G of the bank is exposed to the outside or is newly formed on the bank, it is preferred that the ground G be well leveled to establish an environment in which seeds can well grow later. By way of example, soils of the ground may be finely cracked and smoothed, or organic or inorganic fertilizers may be mixed thereto as nutrients for germinating and growing the seeds.

The method of constructing a bank in an environment-friendly way comprises the step of sowing seeds directly in the ground G and then covering an anti-sweeping fabric 110 on the ground (S 12). In the preferred embodiment of the present invention, seeds are directly sowed in the ground G. At this time, how to sow seeds is not specifically limited. For example, a worker may scatter seeds manually, may sow seeds at regular intervals or may scatter or sow seeds by means of a sowing machine. Alternatively, the seeds are mixed with soils containing nutrients to make a planting soil which in turn is placed onto the leveled ground of the bank to form a planting soil layer, so that the seeds can be sowed therein.

In the present invention, the seeds are not specifically limited but can be selected depending on the conditions of the ground G to which the construction method of the present invention is applied. For example, in the case of a river where water always flows and there are a lot of reeds, it is preferred to plant seeds of reeds. In the case of a cut area in a hill, it is accordingly preferred to plant seeds of bush clovers. In the present invention, after the seeds have been sowed in the ground G, the anti- sweeping fabric 110 is covered on the ground to safely protect the seeds until they are germinated.

In the present invention, the anti-sweeping fabric 110 has a primary function of preventing the ground G with seeds sowed therein from being swept due to rain or the like.

If it rains lightly enough to slightly wet the ground after seeds have been sowed, there is no problem. In a case where it rains heavily, however, the rain does not come into direct contact with the ground but flows along the surface of the anti-sweeping fabric 110. In particular, if it pours within a short time due to a local downpour or during the rainy season before the seeds are germinated to take root in the ground, a newly constructed working region can be easily swept. Therefore, the anti-sweeping fabric 110 allows the sowed seeds to easily withstand such climate conditions.

Further, in the present invention, the anti-sweeping fabric 110 has a secondary function of preserving the subterranean heat of the ground G. In a case where the temperature drops suddenly at night, the anti-sweeping fabric 110 can naturally preserve the subterranean heat of the ground G since it is brought into direct contact with the ground

G.

Furthermore, in the present invention, the anti-sweeping fabric 110 has a tertiary function of acting as a nutrient of the plant after a certain time passes. To this end, the anti-sweeping fabric 110 is preferably made of a material that can be decomposed spontaneously after a certain time passes. The reason is that the anti-sweeping fabric 110 does not hinder the germination and growth of the seeds sowed in the ground but can become the nutrients of seeds when the seeds sowed in the ground G are germinated to the outside. Considering such factors, the anti-sweeping fabric 110 is preferably made of a natural fabric.

The method of constructing a bank in an environment-friendly way according to the present invention comprises the step of covering a steel gabion 130 on the anti-sweeping fabric 110 (S 13).

In the present invention, the steel gabion 130 is installed on the anti-sweeping fabric 110 to serve to press down and hold the anti-sweeping fabric 110. Thus, the steel gabion may have any shape, so long as it can press and hold the anti-sweeping fabric 110. The steel gabion may take the shape of a rectangle or hexagon. Alternatively, the steel gabion may be formed into a pentagonal shape obtained by inserting a reinforcing steel wire into the hexagonal mesh. Further, the term 'steel gabion' is used to better understand the present invention, but a perforated steel mesh or plastic mesh capable of performing the above functions can also be included in the scope of the present invention.

In the present invention, since the steel gabion 130 gently presses down the anti- sweeping fabric 110 which in turn entirely presses the ground G. Therefore, the ground G at the working site will not be swept due to a local downfall or during a long rainy season after the construction.

The method of constructing a bank in an environment-friendly way according to the present invention comprises the step of driving fixing members 140 into the inclined surface of the bank to firmly fix the steel gabion 130 to the ground (S 14).

In the present invention, the fixing member 140 serves to firmly fix the steel gabion 130 to the ground G. In the prior art, the steel gabion 130 is fixed by means of fillers such as stones filled in the gabion. However, since the fillers are not used any longer in the present invention, the fixing member 140 should be additionally employed. At this time, common piles, hooks, hooking nails or the like may be used as the fixing member 140 to firmly fix the steel gabion 130 to the ground G. In the present invention, the fixing member 140 preferably includes an anchor 142 and an anchor coupler 144, which have been separately developed, in order to more easily and efficiently perform the construction method of the present invention.

FIG. 7 shows a case where the anchors 142 are driven into the ground at a predetermined crossing angle with each other, and FIG. 8 shows a case where the anchors 142 are coupled in parallel with each other but diverges at a predetermined angle toward the ground.

In the present invention, the anchor 142 may be replaced with a nail or pile, and two anchor couplers 144 are preferably grouped into one pair such that a space 146 for accommodating the anchors therein is defined between the couplers. The anchor 142 is inserted into the space 146, and both anchor couplers 144 are coupled with each other to firmly fasten the two anchors 142 to each other.

At this time, since the anchors 142 are firmly driven into the ground G at the predetermined crossing angle, they are firmly fixed to the ground as compared with a case where the anchors are driven perpendicularly into the ground. Therefore, the steel gabion 130 is not pulled out or removed from the ground G even though extremely strong force is applied to the gabion mesh from the outside.

In addition, the anchors 142 and the anchor couplers 144 are preferably covered with an anchor cover 148. The anchor cover 148 serves to protect the anchors 142 and the anchor couplers 144 and also functions as a marker for distinguishing the kinds of seeds sowed in the ground.

Preferably, the construction method of the present invention further comprises the step of additionally covering the anti-sweeping fabric 110 with a screen 120 which has meshes smaller than those of the steel gabion 130.

In the present invention, it is preferred that the screen 120 have smaller mashes than those of the steel gabion 130 in order to prevent the anti-sweeping fabric 110 from being separated from its original position due to a local downfall or during a rainy season.

Embodiment 2

A method of constructing a bank in an environment-friendly way according to another embodiment of the present invention will be implemented. This embodiment keeps the accent on how to simply and rapidly construct an inclined surface or the like.

In this embodiment, seeds are not sowed directly in the ground during the construction process but are sowed indirectly using a seeding mattress 150 in which seeds are already sowed. Hereinafter, the second embodiment of the present invention will be described in more detail.

The method of constructing a bank in an environment-friendly way according to this embodiment of the present invention comprises the step of forming a cut area or a bank in a creek, watercourse or river, and then leveling the ground G (S21).

In the second embodiment of the present invention, the manner or way of forming the ground G is substantially identical to that of the first embodiment. Thus, the ground G may be a ground of the completely constructed bank or cut area, or a ground of a bank from which conventional cement blocks or bank protection blocks are removed.

The environment-friendly bank construction method of the present invention comprises the step of spreading a seeding mattress 150 on the aforementioned ground G (S22). The second embodiment of the present invention is different from the first embodiment in that seeds are not sowed or planted directly in the ground G.

In the present invention, the seeding mattress 150 is prepared by beforehand sowing seeds therein, and it is basically held by the steel gabion 152.

FIG. 9 is a schematic view showing the seeding mattress 150 suitable for performing the construction method according to the second embodiment of the present invention.

Further, FIG. 10 is a partial cut-away view showing a state where the construction has been completed using the seeding mattress according to the second embodiment of the present invention. In the present invention, the seeding mattress 150 includes a steel gabion 152 having rectangular, pentagonal or hexagonal meshes. The steel gabion 152 is basically formed into a rectangular or hexagonal shape using two twisted steel wires, but it may be formed into a pentagonal shape using three twisted steel wires, which is more preferable in view of strength reinforcement. The steel gabion 152 holds the entire seeding mattress 150 to keep the original shape of the seeding mattress.

In the present invention, the seeding mattress 150 includes a seed mattress 154 arranged on the steel gabion 152. The seed mattress 154 is a mattress where seeds to be planted in the ground is sowed beforehand. The seeds planted in the seed mattress 154 are not germinated before the construction work, but the seed mattress allows the seeds to be germinated therein after the construction work has been completed. In addition, the seed mattress 154 is preferably made of a material that can be decomposed and changed into nutrients after the seeds have been germinated. To this end, for example, the seed mattress 154 is preferably made essentially of a plant material such as rice straw, barley straw, cornstalk or hay. In the present invention, the seeding mattress 150 preferably includes the steel gabion 152 arranged on the seed mattress 154. The steel gabion 152 is substantially identical to the aforementioned steel gabion, and thus, detailed descriptions thereof will be omitted herein.

More preferably, the seeding mattress 150 of the present invention further includes a screen 156 between the steel gabion 152 and the seed mattress 154. The screen 156 is used to better store and hold the seed mattress 154 and preferably has smaller mashes than the steel gabion 152. In this case, the seed mattress 154 can be more easily held by the screen 156.

Furthermore, the method of constructing a bank in an environment-friendly way according to the present invention comprises the step of driving a fixing member 140 into the bank or the inclined surface to firmly fix the seeding mattress 150 to the ground (S23).

In the present invention, the fixing member 140 of the second embodiment is substantially identical to that of the first embodiment, and thus, a detailed description thereof will be omitted herein. In addition, the method of fixing the seeding mattress to the ground is also identical to that of the first embodiment, and thus, a detailed description thereof will be omitted herein.

Embodiment 3

A method of constructing a bank in an environment-friendly way according to a further embodiment of the present invention will be implemented. The third embodiment of the present invention is useful when it is difficult to sow seeds directly in a working site.

In this case, the ground is first leveled, and a space for sowing seeds therein is then defined while its protection means is prepared. Finally, the seeds are sowed in the ground. To this end, during the construction process, the seeds are beforehand mixed and then scattered through a mechanical operation. Hereinafter, the third embodiment of the present invention will be described in more detail.

The environment-friendly bank construction method of the present invention comprises the step of forming cut area or a bank in a creek, watercourse or river and then leveling the ground (S31). In the present invention, the step S31 of leveling the ground is substantially identical to the steps SIl and S21 according to the first and second embodiments.

The environment-friendly bank construction method of the present invention comprises the step of covering a steel gabion 130 on the ground (S32).

In the third embodiment of the present invention, the ground G is leveled and then covered with the steel gabion 130. At this time, the steel gabion 130 is preferably identical to that of the first embodiment. However, in step S32 of covering the steel gabion 130 on the ground according to the third embodiment of the present invention, the steel gabion 130 is preferably covered in such a manner that it is not brought into close contact with the ground G but a certain space can be defined between the steel gabion 130 and the ground G. The steps of covering the steel gabion on the ground according to the first and third embodiments are different from each other in this regard. To form such a space, a spacing member (not shown) may be employed. The spacing member allows the steel gabion 130 to cover the ground G in a state where the steel gabion is spaced apart from the ground G by a predetermined distance (i.e., the thickness of the spacing member). Further, the an environment-friendly bank construction method of the present invention comprises the step of driving a fixing member 140 into the bank or inclined surface to firmly fix the steel gabion 130 to the ground (S33).

In the third embodiment of the present invention, the fixing member 140 is identical to that of the first embodiment, and thus, a detailed description thereof will be omitted herein. In addition, the method of fixing the steel gabion to the ground using the fixing member 140 is substantially identical to that of the first embodiment, and thus, a detailed description thereof will be omitted herein.

Furthermore, the method of constructing a bank in an environment-friendly way according to the third embodiment of the present invention comprises the step of scattering a planting soil mixture, which is obtained by mixing seeds with soil into a dilute water solution, over the ground (S 34).

In the present invention, the planting soil mixture is obtained by dissolving soil into water in the form of a washy solution and then putting and mixing seeds into the solution.

The planting soil mixture preferably contains a small amount of nutritive ingredients for the seeds such that the seeds can grow well, if required. Once prepared, the planting soil mixture provides an environment where the seeds can grow. Thus, the planting soil mixture is preferably prepared in consideration of the germination time of the seeds to be sowed. The seeding mattress of the second embodiment has an advantage in that it can be made at other places and then carried to the working site but has a disadvantage in that a germination time of seeds may be missed if a long time passes after it has been made. However, since the planting soil mixture of the third embodiment is directly prepared at the working site, there is no possibility of missing the germination time.

The third embodiment of the present invention is much more useful at an area to which it is difficult for a worker to have access. Such an area may include a steep bank or a cut area in a hill. In a working area difficult to access, the worker can merely install the steel gabion 130 to be spaced apart from the ground G by a predetermined space and spray the planting soil mixture toward the ground at a strong pressure. At this time, if the planting soil mixture is sprayed at the strong pressure and reaches the ground, it is attached to the ground. In addition, since the steel gabion 130 is positioned over the ground, the planting soil mixture is not detached from the ground G. Therefore, the seeds in the planting soil mixture are germinated as time goes by.

FIG. 11 shows a case where the environment-friendly construction method of the present invention is applied to construct an inclined surface of a river having a relatively large basin. FIG. 12 shows a case where the environment-friendly construction method of the present invention is applied to a small river in the neighborhood of farmland or the like. The construction method of the present invention may also be applied in a continuous way to the case shown in the figure.

According to the environment-friendly construction method of the present invention, there are advantages in that the construction can be performed without using any fillers, and that the germinated plants can be implanted and grown more easily than the prior art since the fillers such as stones is not filled in the ground.

[INDUSTRIAL APPLICABILITY] The environment-friendly construction method of the present invention so configured can be usefully applied to a variety of banks, inclined surfaces, cut areas or small rivers in the neighborhood of farmlands.

Though the environment-friendly construction method according to the present invention has been specifically described above, the description has been made only in connection with the most preferred embodiment of the present invention. The present invention is not limited thereto, and the scope of the present invention is defined by the appended claims.

Further, it will be apparent that those skilled in the art can make various modifications and changes upon reading of the description without departing from the scope of the present invention.
