Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a greening sheet. More specifically, the present invention relates to a greening sheet for greening slopes such as embankments, excavated portions of slopes, and standing surfaces such as wall surfaces of structures.

[0002]

2. Description of the Related Art In recent years, for aging and conservation of slopes, technological innovations have been made from mortar work to greening, and various greening basic works or vegetation works have been performed depending on the environment. However, such vegetation is one that assembles structures mainly composed of heavy objects such as concrete and metal using heavy equipment from the viewpoint of being able to cope with steep slopes and having a structure that can withstand heavy rainfall. However, the construction cost is huge.

In recent years, importance has been placed on the conservation of natural environment or species of animals and plants, and in conservation works such as slopes, there is an increasing demand for restoration of native tree species and harmony with the landscape. As for the construction method, demands for cost reduction are increasing. In order to meet such demands, various construction methods such as vegetation mat construction, vegetation sandbag construction, container spraying construction, stair vegetation construction, etc. have been developed, but the applicable range is wider and steep slopes can be preserved. Development of construction method is desired.

In urban areas, heat islands have become a problem, and rooftop greening is becoming widespread. However, the rooftop area that can be vegetated is extremely small compared to the area of the area. There is a limit, and it is expected that the wall surface will be greener than the roof.

As a wall greening method, there has been proposed a method in which a net is stretched over the wall surface of a building, and a large number of flower pots are hung on the net at intervals, and vines are planted on the net (Japanese Patent Laid-Open No. Hei 5). -2119836). However, this construction method has a limit in the area of greening area, the decorative use as a three-dimensional flowerbed, and other versatility, and there is a problem in aiming for a wide range of applications with good workability on a large scale, and it cannot be considered a practical method. It was
Further, the net and the flower pot are not integrated, and the flower pot is liable to be shaken by the external force of the wind and is unstable, which is not a practical method.

[0006] In order to effectively green the slopes and preserve the slopes, it is necessary for the plants to grow, and for this reason, the roots of the plants grow by eating into the slopes and drought. It is necessary to withstand frost damage, typhoon, etc., and to form a strong network of roots so that sediment collapse does not occur. It is necessary for the roots to grow.
For this purpose, it is necessary that the vegetation soil is in close contact with the slope after the greening work.

Slope vegetation work using seedlings has conventionally been vegetation sandbag work and container seedling vegetation spraying work. Furthermore, as a method of suspending a bag body with an open upper part, a long vegetation soil holding method is used. A method has been proposed in which a reticular body is provided with slack on the slope (Japanese Patent Laid-Open No. 10-2048).
87). The revegetation using this mesh can be constructed with lightweight materials, has flexibility, is easy to carry and install, and has a steep slope even when the slope is uneven. If it is not, the contact area between the soil and the slope can be kept large by the gravity of the soil itself, but there is a problem that a satisfactory contact area cannot be obtained when the slope becomes steep or the unevenness is severe. is there.
