Abstract

PROBLEM TO BE SOLVED: To contrive stabilization of greening vegetation by attaching a vegetation soil outflow prevention member to the front wall of a futon cage and providing the filling space of vegetation soil on the step part of the crest of the futon cage. SOLUTION: A futon cage is filled with unscreened gravel, gravel soil, floor digging production soil and sand, concrete waste or the like. A vegetation soil outflow prevention member 3 of height which is composed of a plurality of small-diameter logs 5 on the front wall 2 of a one-stage futon cage and in which necessary depth of vegetation soil having a vegetation kind can be secured is mounted. A two-stage futon cage is piled and the step part 1 of the crest of the one-stage futon cage is utilized to provide the filling space 4 of the vegetation soil. The vegetation soil outflow prevention member 3 is attached to the front wall 2 of the two-stage futon cage, and the intrusion gap 6 of a root stem is provided between the small-diameter log 5 of the vegetation soil outflow prevention member 3 and the step part 1. Furthermore, the futon cages of three-stage, four-stage... are piled. Thereby stabilization of greening vegetation can be contrived.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims at stabilizing the vegetation of a futon basket for a long period of time and attaching a small-diameter log (or a half log) 5 to the front wall 2 so that the futon basket is integrated into the natural environment. It is about aiming at a structure.

[0002]

2. Description of the Related Art Greening of futon baskets has been promoted. For example, it is supported by using a greening bag or the like having a retaining wall area which is adopted when there is a restriction on a construction site (a riverbed or the like), or by a method of covering with soil when a steep slope is taken. However, natural extinction and instability of the soil cover due to the vertical greening surface in the case of retaining wall unavoidable are inevitable, and in any case, it is difficult to achieve long-term stable greening.

[0003]

SUMMARY OF THE INVENTION The present invention stabilizes the unstable state of the conventional revegetation method and considers the natural environment.
Furthermore, it was invented as a method of construction that takes into account the ecosystem.

[0004]

A vegetation in which vegetation soil is stably fixed by using a top end step 1 for mounting a vegetation soil loss prevention member 3 on a futon basket front wall 2 and stacking the next futon basket. A soil filling space 4 is provided. Further, the vegetation soil loss prevention member 3 is configured to have a small diameter log (or a half log) 5.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (1) The amount of vegetation soil without waste is changed by changing the depth of the space 4 between the vegetation soils according to the purpose of revegetation, such as grasses, trees and shrubs. In this way, the purpose of greening can be achieved. (2) Herbs and trees grow quickly, and when the plant grows to about 50 cm in height, they form a shape that covers the front wall 2, and the front wall 2 of the futon becomes green. (3) The invasion of native species is obvious, and it is expected that the native species will return to the natural environment without waiting several years. (4) The filling material of the futon basket is originally limited to cobblestone or chestnut stone. It is feared that these may eventually become depleted. Therefore, the front wall 2 is covered with logs as in the present invention. By doing so, it is possible to mix concrete waste material in addition to locally generated soil, such as cut gravel and gravel soil, and even excavated soil, without being particular about the particle size of the packing material. It can be used for materials. These materials are also suitable for vegetation and become two birds per stone, leading to effective use of the materials.

[0006]

(1) The stabilization of the vegetation and the diversification of the selection of the filling material according to the present invention, and the provision of the rhizome intrusion gap 6 according to the third aspect of the present invention are that the rhizome of the vegetation is deep in the futon basket. Penetrates into the root and develops the entanglement of the rhizome, forming a form that covers the entire bedding basket. This also reinforces the corrosion of coated small logs over time, and it is expected that the entire bedding basket will return to nature. (2) The futon basket front wall 2 is a small-diameter log (or a half log) 5
This prevents swelling and deformation of the front wall 2 which is inevitable during the work of filling the filling material, and eliminates the need for a filling work and an installation of a reinforcing work by an input to prevent such a problem. This enables full-scale mechanical construction, which leads to more efficient work and shorter construction period. (3) The use of the small log (or half log) 5 of the present invention is part of the expansion of the use of thinned timber, which is necessary for revitalizing forests, especially the afforestation areas, where the forest industry in Japan is steep. It is good to expect that it will lead to
