や自然景観を損なう結果となっている。2. Description of the Related Art Conventionally, revetment works for rivers, lakes, and marshes have been carried out using stone work, concrete block work, and the like.
Many construction methods have been used, such as a method of forming a frame, a method of forming a block mat, a method of injecting a mortar made of cloth, a method of forming a serpentine cage, and the like.
However, due to excessive emphasis on safety against floods and ease of maintenance, the natural environment and the natural environment of rivers, lakes and marshes, as typified by three-sided waterways, were impaired. Has become.

態系の復元・修復を行う緑化工法である。[0003] For this reason, in recent years, a multi-natural type waterway with a function of creating a habitat for aquatic animals and plants and purifying water quality has been provided in recent years by protecting and protecting the slopes and actively greening the waterside by vegetation. Various types of revetment construction have been attempted. One of the typical construction methods is to use a flexible seawall made by filling coconut fibers at a high density inside a nylon tubular bag body for rivers,
Lakes and marshes, laying on the shores of regulating ponds, etc., as a growth base for aquatic plants, while plants grown sufficiently in the field, planted on the flexible seawall, watering greening and This is a greening method that restores and restores the ecosystem.

不自然な印象を与えることになる。In the above-mentioned conventional greening method, a great deal of labor is required for the maintenance and transportation of the plant to be planted, and the plant is planted on a flexible seawall at the construction site. The workability is poor. Moreover, since it is a flexible seawall filled with coconut fibers in a tubular bag, it has a low specific gravity, and it is difficult to fix the flexible seawall in a rapid stream or a sandy bank. It is necessary to use it in combination with a serpentine-shaped seawall material in which a nylon net is filled with stones, and two types of seawall materials are prepared and combined, so the construction is very troublesome. In addition, when the flexible seawall and the serpentine-shaped seawall are alternately laid, the serpentine-shaped seawall has no vegetation and is striped green.
It gives an unnatural impression.

In some cases, however, the conventional reclamation method requires a long construction period and high costs.

Flexible seawalls that can efficiently construct multi-natural waterways and seawalls with aquatic plant and animal habitat creation and water purification functions, and have good responsiveness to changes in the ground. It is an object of the present invention to provide a flexible vegetation floating body capable of easily forming an artificial floating island for vegetation, and a greening method using the same.

Therefore, the responsiveness to changes in the ground after laying, for example, uneven land subsidence, erosion, uplift, and the like is improved, and further changes can be effectively prevented.
【００３３】また、石の重みにより定着性が良好であ
り、分断されることもなく、河川の防災性にも優れる。Further, the fixing property is good due to the weight of the stone, and the stone is not divided, and the disaster prevention property of the river is also excellent.
【００３４】一方、施工に際しては、地盤の不陸や起伏
にもよく追従するため、施工対象地盤の修正が軽微でよ
く、施工作業性にも優れたものとなる。On the other hand, during construction, the ground following the unevenness and undulation of the ground is well tracked, so that the ground to be constructed can be modified only slightly and the workability is excellent.
【００３５】また、その可撓性の筒状袋体内に、発泡粒

をも図れ、特に、ダム湖岸の緑化をダイナミックに図る
ことがきる。The flexible tubular bag is filled with a mixture of expanded granules, lightweight soil, aqueous plant seeds, root stocks and the like to give buoyancy and float on the water surface. As a result, it is possible to create an aquatic animal and plant habitat on the surface of the water at an early stage at a low cost, and it is possible to protect the ecosystem over a wider range. In addition, purification of water quality and improvement of the landscape can be achieved, and in particular, greening of the dam shore can be dynamically achieved.
