Document Type and Number:
Japanese Patent JP3301513
Kind Code:
B2
Abstract:
PURPOSE: To form tree-planting concrete, which has the large extension space of a root and requires no trouble on sprinkling, by previously filling forms mounted on a slope ground with a vegetation foundation bed, into which a plant body is buried previously, and injecting mortar, etc.
CONSTITUTION: Soil, a fertilizer, cork, nonwoven fabrics, urethane foams, glass wool, vegetable fibers, and a porous or multi-cellular substance are mixed to manufacture balls having water retention characteristics, air permeability and water permeability, and plant bodies such as seeds, bulbs, roots, seedlings, etc., are buried and wrapped in a net made of plastics, thus forming a vegetation foundation bed 11. Forms 21 are installed onto a ground 1 such as a river slope- face, and compacted properly, and the vegetation foundation beds 11 are brought into contact by certain force mutually, and pushed and filled previously into the forms 21. Mortar 23, into which a water-reducing agent and a foaming agent are mixed, is injected into the forms 21 through a pipe 22, and prepacked concrete execution is conducted. Mortar 23 is cured, and the forms 21 are removed, thus forming tree-planting concrete 24.
