Construction method for ecological restoration in rivers

The present invention relates to a construction method for ecological restoration of rivers, in particular, to provide a growth environment for the growth of riparian plants in rivers or rivers, to prevent erosion of the rivers by planting the riparian plants, and to improve the natural quality of water The present invention relates to a construction method for ecological restoration of rivers that can restore and create an ecological environment such as fish and algae.

Conventionally, stonework or concrete retaining wall was installed to cause the adverse function of blocking the aquatic ecosystem. Recently, a box-type closed structure was developed, but this also failed to secure the continuity of the aquatic ecosystem. Or loss of water from floods.

As described above, the stonework and the concrete retaining wall serve as a barrier to block the space where the river water and the embankment can contact, thereby damaging the habitat and spawning place of the small animals as well as the riverside insects in the embankment. It is responsible for the restoration of the ecosystem, such as making the habitat difficult, and counterproductive.

Therefore, even if the flow increases rapidly due to the heavy rain and the flow velocity becomes faster, the underground ecosystem and the underwater ecosystem can be freely interchanged with the dimensional function beyond the retaining wall, so that the river and the groundwater can easily exchange with each other depending on the situation. The need for developing methods to provide good habitats for fish, algae, and other fisheries, together with riparian insects and herbivore.

In addition, the flow rate of the domestic rivers are rapidly increased due to the heavy rains accompanying the rainy season or typhoon, the flow rate is very fast, and the reservoirs of the rivers are often eroded and lost. As a result, the safety of the levees is threatened, especially the waterside plants of riversides such as reeds and willows are lost, thereby destroying the natural purification function of river water quality and the habitat and ecological environment of fish and algae. The damage and aftermath is very large.

Therefore, in order to cope with such flood damage, conventionally, structures such as concrete retaining walls and stone masonry have been constructed on riversides. However, such a structure such as a concrete retaining wall or a stone masonry has excellent structural stability, but has a great adverse effect on the ecosystem of the river by isolating water and soil in the channel and removing the growth space of the riparian plant. Recently, a method of constructing an aquatic biological habitat facility using palm fiber networks, etc. has been attempted, but there is a vulnerability that cannot fundamentally prevent erosion and loss of riverbanks caused by rapids.

The present invention was created in view of the above matters, and prevents the erosion of the waterside of rivers and rivers, restores the natural water purification function, creates an ecological environment that can create a habitat environment such as fish and algae, To prevent spills of small gravel, etc., during growth of waterside plants, they have excellent protection of watersides and slopes, and provide construction methods for ecological restoration of more ecologically superior rivers by increasing the environmental properties by sticking plants suitable for local conditions. There is this.

The present invention comprises the steps of punching a plurality of vertical pile members for the construction of a water barrier in the ground of a certain point of the reservoir side of any river;

Installing a water barrier in the longitudinal direction of the waterway side of the river to prevent the soil outflow to the plurality of vertical pile member;

Laying clay clay in the downstream of the river where the water moist is installed;

Sprinkling water plants on the upper surface of the laid soil; And

It provides a construction method for ecological restoration of the river comprising the step of covering the protection net is fixed to the waterway side by using an underwater anchor on the waterfront plant.

In addition, after laying the clay soil to provide a construction method for ecological restoration of the river, characterized in that it further comprises the step of covering the jute mat on the top of the soil.

In addition, the protection net provides a construction method for ecological restoration of the river, characterized in that made of one of jute net, wire mesh, polypropylene resin network, biodegradable resin network, geogrid, geotextile, PP net, PE net. .

In addition, the underwater anchor has a "V" shape of the wing side connected to face each other, the outer side is bent in a streamlined shape so that each wing side is outward, the through-hole is formed on one side of each wing side, each wing side is connected to the term Provides a construction method for restoring the ecology of the river, characterized in that the main body is formed in the center of the other surface and the iron wire is connected to pass through the body wing side fastening hole.

As described above, the construction method for restoring the ecology of the river's reservoir by the problem solving means of the present invention is rooted so that the water vegetation can grow on the bank of the river reservoir with the risk of erosion or loss. By providing space to settle down and planting waterside plants there, there is an advantage to prevent erosion of river reservoirs, to restore the natural water purification function, and to create a habitat environment such as fish and algae.

In order to achieve the above object will be described in detail through the following detailed description and drawings.
