Description

Greening Method for Protecting Banks

The present invention relates to a construction method for greening the river banks, more specifically, is installed on the concrete lake surface of the river so that the soil is not lost by the water flow to maintain a stable vegetation vegetation can be made effectively and beautiful It is about a lake reclamation method that can create greening area.

Recently, the river environment has been changed significantly as the land use of the river basin has been increased and urbanization has progressed. This change in the river environment has been accelerated because the river environment maintenance method has been focused on large-scale civil works for watershed purposes. Natural environment functions are degraded. In addition, water pollution in rivers, as well as ecosystem components, decreased the density of fish and algae in the river vegetation and streams, and reduced diversity of habitats.

Especially in urban rivers with high density of land use around rivers, the river environment was developed for the maintenance of reservoirs and reservoirs for the purpose of flood communication, the linear maintenance of river channels, and the construction of river banks. It was constructed.

For example, the maintenance of existing rivers using concrete was carried out mainly on large-scale civil works for watershed and completion purposes, with little consideration for the river ecosystem, and the natural natural functions of the rivers were almost destroyed. As a result, of course, the water quality of the river is contaminated. In addition, the concrete revetment physically blocks the infiltration of river water into the soil layer, which not only regenerates natural wetland vegetation, but also changes the water temperature when the shade provided by the natural vegetation disappears. Extreme loss of function as aquatic benthic, fish habitat, and spawning sites, followed by feeding around the celestial vegetation and damaging the habitat of algae hiding in vegetation dumble.

In addition, the slopes of the rivers are very high in ecological productivity and biodiversity, and they are the part of the boundary between underwater and land in the natural river ecosystem. Blocking this part with a normal concrete block breaks the link between the underwater and terrestrial ecosystems, resulting in almost extinction of plants and animals that primarily inhabit the transition zone, and secondarily has a significant negative impact on the entire river ecosystem.

In addition, since the bottom of the concrete stream and the inclined surface physically blocks the river water infiltrates into the soil layer, as described above, the natural riverside vegetation is grown, and the shade provided by the riverside vegetation disappears.

The conventional process of converting a slope such as a riverside covered with a concrete layer into a natural environment is to remove and remove the concrete layer in the current state, and then cover it and apply a grid mat. It was to plant vegetation on it.

However, such a conventional method was expensive because the repair work had to be once removed from the inclined surface, and the removed concrete layer had to be disposed of separately.

Thus, instead of walking and removing the concrete layer, the soil was covered with soil on the concrete layer, and then a plant was planted thereon. However, this conventional method has a problem that the root of the plant does not grow in a stable state due to the loss of soil in a short time or the lack of effective soil due to the rapid flow rate of water flowing in the river. Therefore, after the plant vegetation, the revetment of the revetment surface vegetation in the same manner as the conventional method is that some of the planted plant is lost after some time, or the problem of dying sensitive to drought due to the inhibition of root development.

As the interest in the river environment has increased recently, attempts have been made to regenerate and restore ecologically damaged river environments, but the damaged river environment due to the lack of research and development of methods and materials that make them economically and technically feasible. The recovery and recovery of the situation is only a relief.

The present invention is to solve the conventional problems as described above, the object of the present invention is to provide a revetment and reclamation method that can effectively recover and restore the ecologically damaged stream environment by making the vegetation on the concrete revetment surface of the stream effectively have.

As described above, according to the present invention, the plant vegetation is effectively performed on the concrete lakeside of the river, thereby obtaining an excellent effect of effectively regenerating and restoring the ecologically damaged river environment.

According to the present invention, natural stone or sand stone, soy gravel and sand loam are sequentially filled in a grid block at an appropriate ratio, thereby improving stability and resistance to external force of the revetment surface made of concrete, and effectively preventing soil from being washed out by water. It can supply water and nutrients to the roots of vegetation plants stably. Therefore, the lakeside of the river can be beautifully recorded, and accordingly, the restoration of the river ecosystem as well as the beautiful urban environment can be achieved.

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

The revetment recording method 1 according to the present invention is made using a grid block and a vegetation mat, as shown in FIGS. 1 and 2.

In the revetment method (1) according to the present invention, first, a step 10 of installing a lattice frame forming a plurality of spaces on a concrete revetment surface C made of river transition concrete is made.

As shown in FIG. 3, the grid block 12 has a structure in which the respective blocks 12 are fitted up and down, and each block 12 has a structure in which the respective blocks 12 are rotated by a predetermined angle to each other. It will be able to be mounted stably on the river's lake surface at the desired angle. As a preferable structure of the grid frame block 12, Utility Model Registration No. 0380759 (name: prefabricated grid block) developed and applied by the applicant of the present invention can be used.

In the present invention, a step 20 of filling the natural stone or the dead stone 22 in the lattice block 12 is made. The natural stone or dead stone 22 has a diameter of 120 mm to 250 mm and an average diameter of 150 mm, and is filled in the inner space of the grid block 12 in a close form as shown in FIG. 4.

Such natural stone or sandstone (22) improves the safety of the riverside banks, and serves as an energy defense role against external forces, that is, resistance to external forces to prevent destruction of the lakeside by the water flowing in the river.

And the present invention comprises the step (30) of filling the bean gravel 32 in the space between the natural stone or dead stone (22).

The bean gravel 32 has a diameter of 15 mm to 30 mm and an average diameter of 15 mm, and as shown in FIG. 5 in the inner space of the grid block 12, the natural stone or the sand stone 22 It is closely packed in the spaces between.

The soy gravel 32 serves to prevent sand loam, ie, sand, which is described later, from being swept away by the water flowing from the stream. In other words, soy gravel 32 is filled with sand loam between them to prevent the loss of soil by protecting the waterway of the river. In addition, by filling the space between the natural stone or dead stone (22) also performs a function to more securely fix them.

Next, the present invention comprises the step (40) of filling the loam 42 in the space between the soy gravel (32). The sandy loam 42 is sand having an average diameter of 0.2 mm, and closes the pores formed in the space between the soy gravel 32, as shown in FIG. 6, and supplies the vegetation plant with moisture and nutrients.

Meanwhile, the filling step 30 of filling the bean gravel 32 in the space between the natural stone or the dead stone 22 and the filling of the sandy loam 42 in the space between the bean gravel 32 are 40 Although each made of a separate process, the present invention is not limited thereto.

That is, in the present invention, the soy gravel 32 and the sandy loam 42 are mixed in advance in an appropriate ratio, and for example, so as to correspond to the weight ratios of natural stone or dead stone 80%, soy gravel 16% and sandy loam 4%. By adjusting the weight ratio of the soy gravel and sandy loam and mixing them in advance, they can be simultaneously filled in the space between the natural stone or sandstone 22. That is, the step 30 filling the bean gravel 32 and the step 40 filling the sandy loam 42 may be simultaneously performed in one process, thereby achieving an effective process shortening.

After filling the sandy loam 42 as described above, a step 50 is performed to compact the interior of the grid block 12. The water compaction is carried out in this manner so that the natural or dead stone (22), soy gravel (32) and sandy loam (42) layers are more closely filled.

And the present invention preferably after the water compaction step 50 as described above in the lattice block 12, the natural stone or sandstone 22, soybean gravel 32 and sandy loam 42 in the second repetitive charging in sequence And, to form a soil-filled layer with a multi-layered soil structure, including the step of compacting the water second. That is, after the water compaction step 50, the lattice block 12 is secondarily filled with natural stone or dead stone 22, and the bean gravel 32 is placed in the space between the natural stone or dead stone 22. Secondary filling step of filling the secondary loam (42) in the space between the bean gravel 32 and second compaction of the inside of the grid block 12 to form a multilayer structure (60) It will include.

Thus, the multilayer structure of soil filled in the grid frame 12 corresponds to the height of the grid block 12 and has a filling depth of approximately 300 mm.

If the filling depth of the soil exceeds 300mm, the vegetation conditions are improved by increasing the free space for plant roots, but the width of the river is relatively narrow, which may cause a problem of increasing the level of the river.

On the contrary, when the filling depth of the soil is relatively low, the space where the root of the plant is taken down becomes disadvantageous to the vegetation condition of the plant.

Thus, if the spaces of the grid block 12 are filled with natural stone or sandstone 22, soy gravel 32 and sandy loam 42, they are 80% natural stone or sandstone 22 and 16% soybean gravel 32. And sandy loam 42 at a weight ratio of 4%. Therefore, when filled in the proper ratio, it is possible to effectively prevent the rooting of plants and the loss of soil in the revetment surface made of concrete, and to stably supply the vegetation of plants by supplying moisture and nutrients to the plant roots stably. have.

And then the step 70 of sowing the plant seeds in the sandy loam 42 is made. In this case, the seeds to be sown are sown in the sandy loam part, and the vegetation is preferably as shown in Table 1 below.
