RETAINING WALL DEVELOPMENT METHOD FOR REVETMENT CLOSE TO NATURE

摘要

PURPOSE: To maintain natural environment by filling ready-mixed concrete in expansible bag bodies to spread them on a constructing surface, at the same time, preventing the slippage between them, and providing void forming solids between them. ;CONSTITUTION: Developing members 4 filling ready-mixed concrete in various sizes and kinds of expansible bag bodies are spread on a constructing surface. At that time, disc-like solids 6 having projections on both sides of each of them are provided between the members 4 to prevent the slippage and, at the same time, an air lock is formed to make it possible to supply air to roots of plants. After that, if necessary, continuous cellular mats 10 are provided between the constructing surface and members 4, or air/draining pipes 13, seeds, roots, branches, etc., are provided between them to promote permeability and draining efficiency. Seeds and fertilizers are loaded to the members in advance, and vegetation basic materials, etc., are mixed between the members 4. In addition, for promoting void formation, sand, crushed stone pieces are made to adhere to the members 4, or large sized aggregate, organic materials, etc., are mixed with ready-mixed concrete. According to the constitution, water can be purified to maintain ecosystem, and construction can be easily carried out.;COPYRIGHT: (C)1994,JPO
