  In general, a revetment is a work set up on a slope to protect riversides, coasts, and embankments and prevent erosion of waterfront lines by running water. Recently, land use in river basins has increased, and changes in the river environment have begun as urbanization progresses. This kind of change in the river environment has been promoted mainly by large-scale civil works for the purpose of flood control and water use. In particular, the construction of concrete revetments using cement concrete reduces the water density of rivers as well as river vegetation, fish inhabiting rivers and tidal currents as a component of ecosystems, and the diversity of habitats and plants As the nature decreased, the river's function as an ecosystem habitat declined.

  Such a concrete revetment not only physically blocks river water from seeping into the soil layer, but also dries the riverside wet vegetation (wet vegetation) of natural rivers, as well as the shade provided by the riverside vegetation. As the water disappears, a drastic change in water temperature occurs, which damages the river ecosystem that functions as aquatic benthic organisms, fish habitats and spawning grounds, and eventually feeds around the riverside vegetation and hides in the vegetation grass. It also affected the tidal habitat.

  On the other hand, the natural vegetation of rivers provides natural beauty to the surrounding urban residential areas, provides habitats and hideouts for creatures such as small birds and water birds, and prevents waterside erosion due to waves and flow velocities. And the widespread recognition of the importance of such effects can help to restore ecologically impaired river environments due to increased interest in river environments due to such river ecosystem damage. Attempts have been made to recover.

  As an attempt to create such river greening, direct transplanting to transplant turfgrass, mats made by attaching seeds to other rice straw, and seed attachments made by attaching seeds to synthetic fibers Mats are used, but in the case of direct transplanting, it rains a lot or the soil flows down with the rainwater due to river water, so it is easy to lose the soil, and it is difficult to grow turfgrass due to the toxicity of concrete. The rate is extremely low and the creation of green spaces is not efficient, and in the case of a seed-attached mat, it is just a string tied without a separate fixing means supported on the block, so when flooding the revetment, There is a problem that it is very likely that the creation of the green space will fail because the mat will be removed and lost.

  In addition, when using a vegetation mat that can plant predetermined plants on the surface, it is supported by tying it in a lattice shape with a wire for fixing or by driving a fixing pin. Therefore, there is a problem that not only the work for fastening the wire is troublesome, it takes a considerable work time but also the appearance is not beautiful.

  In addition, the wire for fixing the vegetation mat can be damaged over time, and the mat is not firmly fixed to the block using the fixing pins, so that the mat can be easily released. Therefore, when a flood or the like occurs, there is a problem that the mat is lost due to the separation of the mat from the pins due to the flow velocity and buoyancy, and the floating or floating on the block.

  In addition, there have been attempts to remove the constructed concrete revetment and plant waterside plants. However, it takes considerable cost and construction period to remove the already constructed concrete revetment, There is a problem that the revegetation of rivers is not efficient because there is a risk of further damage to the ecosystem.
