Abstract
Description
The present invention relates to an eco-friendly ecological restoration method of river slopes by section for eco-friendly ecological restoration of the slope of the river.
In general, large cities are flooded with embankments due to flooding, resulting in large casualties and property losses. For the purpose of flooding, all existing facades of large cities are covered with mortar blocks.
As described above, by simply constructing the mortar (cement) product in the form of weaving block in the mortar (cement) product as well as there is no space for grass to grow around the block was unable to plant plants.
The surface consisting of such shore blocks not only impairs the aesthetics of urban rivers, but also has a bad effect that plants and animals cannot grow in the natural state.
In other words, when the river slope is constructed with the revetment block of mortar (cement) product as described above, it is not only harmful to the city's river view, but also has serious adverse effects on the natural ecosystem.
In order to solve these problems, construction methods have recently been proposed to prevent the collapse of the slope of rivers and to allow vegetation to take account of urban aesthetics and to restore various ecosystems for ecosystem restoration.
In the urban river ecological restoration method of Korean Patent Registration No. 0414658, a part is set as a partial repair section in the existing method of manufacturing, and a mortar block of the partial repair section is removed to form a law surface, and the bottom surface is roughly sloped. In the ecological restoration method of urban rivers by laying a pile embankment with a vertical pile and a horizontal pile at the end of this gentle slope after laying on the surface, the anti-sucking material is laid on the plain surface, and the seed-bearing soil is stacked on the back of the vertical pile. In addition, the law and the mild slope is laid on the seed-covered crests so that the plants are developed and planted, and the construction method to allow for the formation of a fox in the anti-refractory block and natural heavy stone is installed at a predetermined interval on the existing bed.
The ecological restoration technology is simple in its configuration and can save installation costs for ecological restoration, but when there are a lot of mortar blocks installed, the vegetable parts are reduced so that they do not exert much effect. In the case where there are few installed parts and many parts available for vegetation, there is a weak point that the levee of the lower body is weak and the levee may collapse during flooding.
In the block-type vegetation net of Korean Utility Model Registration No. 240391, a technique for providing a block-type vegetation net that can be economically and efficiently planted as a revetment gabion used for river banks and road slope protection is proposed. In which a rectangular cylindrical mesh is filled with stones and covered with a net cover, and fixed to the bottom end of the mesh, the compounding soil filled thereon, and the stone is put on the compounding soil to fill the voids between the stone and the compounding soil. It consists of one, the middle layer covered on the compounded soil-stone layer, and the green soil filled on the middle layer.
The above-described techniques and the conventional ecological restoration of rivers have generally provided gabions on slopes of rivers, and laminated stones, blended soils and fiber nets to enable vegetation of plants on the installed gabions.
However, the inclined surface of the river differs in the degree of flooding according to its height, and the flow velocity is also different.
For this reason, the layers stacked on the gabions differ in the destructive state depending on the height of the inclined surface, and also in different vegetation plants depending on the degree of flooding and other environmental factors.
Therefore, while stacking stones and mixed soil to allow vegetation to be planted on the gabions installed on the slope as in the prior art, the components and layers stacked on the entire slope without taking into consideration the damage and vegetation caused by the inundation and flow rate of the slope. By equalizing the height of the flooding and the damage caused by the flow rate, there was a disadvantage that can not effectively cope with the vegetation.
In other words, when the degree of flooding is severe as in the lower part of the river slope and the damage due to the flow rate is severe, and when there is little inundation like the upper part of the river slope and there is no damage due to the flow rate, the vegetation plants are different from each other. According to the characteristics, the sections are divided into several sections according to the height of the inclined surface, and the partitioned sections should be differently stacked.
In addition, conventionally, the stone is installed in the same gabion installed on the slope as a whole, and by placing a component capable of vegetation, such as mixed soil on the stone, there is a phenomenon that the lack of some components often occur from the outside, thereby causing ecological restoration There is a disadvantage that the installation cost for the rise.
In addition, in the conventional method of ecological restoration using gabions, gabions are laid on slopes, nonwoven fabrics are placed thereon, stones are placed on the nonwoven fabrics, and gabions are installed thereon, and then, the vegetated soils are covered again. Is made. However, this method has a disadvantage that the root of the plant is weak because the root of the plant is set on the gabion, and also has the disadvantage that the vegetation is damaged due to severe loss of the restored soil when flooded. In addition, there is a disadvantage in that the gabion is installed and a double work is carried out on the restoration soil for ecological restoration.
The present invention is invented to solve the above problems,
According to the height of the inclined surface of the river is divided into a plurality of sections, and by varying the configuration of the layer laminated on the partitioned section is to ensure that the vegetation on the inclined surface of the river can grow well.
In addition, by varying the size of the section partitioned according to various environments, such as the degree of flooding and the flow rate of the inclined surface is to prevent damage due to the flooding and flow rate and to reduce the installation cost.
In addition, the purpose is to allow the vegetation roots to settle on the ground of the slope.
In the eco-friendly ecological restoration method of the river slope to lay a gabion on the inclined surface, to form a variety of layers such as reproductive base material and fiber net so that plants can be planted on the gabion, and install a mattress gabion on the top,
First, the investigation step of closely examining the environmental factors such as the degree of flooding, flow velocity, inclination angle of the river slope; Second, arranging the surfaces to even the slope; Third, the gabion installation step of installing the gabion on the arranged slope; Fourth, partitioning the gabion installed on the inclined surface into a plurality of sections according to the height of the inclined surface to be suitable for environmental factors; Fifth, laminating vegetation soil, field collecting soil, natural fiber net, etc. to enable vegetation for each of the divided sections; Sixth, the method consists of installing mattress-type gabions and arranging the surroundings.
The size of the partitioned section may be formed differently, which is defined according to environmental factors such as the degree of flooding and flow rate for each section.
The inclined surface of the river is usually divided into four sections according to the height, it is preferable to carefully examine and partition various environments such as the inclination angle, height, flooding degree, flow rate of the river.
The section divided into four sections may often be divided into three sections.
The first section is formed in the lower end of the inclined surface of the four partitioned sections, install a gabion on the inclined slope arranged, and install the ecological restoration soil mixed with the seeds selected on the gabions in 25 ~ 35㎜, The natural fiber net is installed in the ecological restoration soil, 100-120 mm aggregate is installed at 265-275 mm on the natural fiber net, and the mattress-type gabion is installed on the aggregate.
The second section is formed in the upper section of the first section, install a gabion on the inclined slope, and install the high quality soil or field collecting soil 55 ~ 65㎜ on the gabion and then compacted and selected seeds and Install 15 ~ 25mm mixed ecological restoration soil, install natural fiber net on the ecological restoration soil, install 100 ~ 120mm aggregate 210 ~ 230mm on the natural fiber net, mattress on the aggregate Consists of the installation of a mold gabion,
The third section is formed on the upper part of the second section, and installs the gabion on the inclined slope, installs the field collecting soil at 145 ~ 155 mm on the gabion, and mixes the ecological restoration soil mixed with the seeds selected thereon. It is installed to ~ 25㎜, and the natural fiber net is installed in the ecological restoration soil, 100-120mm aggregate is installed on the natural fiber net 120-140mm, and the mattress-type gabion is installed on the aggregate Lose,
The fourth section is formed in the upper section of the third section, and the gabions are installed on the inclined slope, and the field collecting soil is installed on the gabions with 145-155 mm, and 40-Vol% of amber stones and vegetation over 120-150 mm are placed thereon. The mixed aggregate mixed with 60Vol% of the possible soils is laid at 145 ~ 155㎜, and the vegetation cover or vegetation-based mounting or firewood is selected according to the site, and the vegetation covering is made, and the mattress-type gabion is installed on it. .
Alternatively, the fourth section is to install the ecological restoration soil mixed with the selected seeds on the inclined surface to 15 ~ 20㎜, lay a fiber net on it, and then install the ecological restoration soil to 10 ~ 15㎜ on it It may be done.
In addition, when the inclined surface is divided into three sections, two sections are merged with one section, or one section is merged into two sections. That is, two sections may be formed in the same manner as one section, or one section may be formed in the same manner as two sections. This is adjusted according to the environment of the inclined surface. That is, when there is a lot of immersion and the flow rate is high, two sections are the same as one section, and when the immersion is low and the flow rate is slow, one section is formed the same as two sections.
The present invention, which is an eco-friendly ecological restoration method of the river inclined surface for each section made as described above, divides the inclined surface into a plurality of sections according to the degree of flooding and the flow rate, and changes the components that are appropriately stacked in the partitioned sections to the inundation and the flow rate. There is a feature that can prevent damage.
In addition, by controlling the amount of use of stones (stones) and reclaimed soil by varying the components to be stacked in each partitioned section, it minimizes the inflow of components such as stones (stones) and reclaimed soil from the outside to save installation costs There is this.
In addition, there is a feature that allows the vegetation to grow well by varying the components stacked according to the height of the slope.
In addition, the ecological restoration soil is located on the lower side of the aggregate, so that the roots of vegetation can grow with roots in the soil of the slope, and in particular, the roots of the plant have roots in the soil of the slope, so that gabions can be formed. There is a feature that can be fixed so as not to move on the slope.
The present invention consists of the following steps.
First, the investigation step of closely examining the environmental factors such as the degree of flooding, flow velocity, inclination angle of the river slope; Second, arranging the surfaces to even the slope; Third, the gabion installation step of installing the gabion on the arranged slope; Fourth, partitioning the gabions installed on the inclined surface into a plurality of sections to be suitable for environmental factors; Fifth, the step of laminating vegetation soil, field harvesting soil, natural fiber net, etc. so as to enable proper vegetation for each partitioned section; Sixth, the mattress-type gabion is installed, and the surroundings are organized.
