NATURAL BANK CONSTRUCTION METHOD FOR MINIMIZING ENVIRONMENTAL POLLUTION OR ENVIRONMENTAL DESTRUCTION THROUGH AN ENVIRONMENTAL-FRIENDLY METHOD IN BUILDING A SLOPE OF A RIVER

摘要

PURPOSE: A natural bank construction method is provided to prevent aggregate from being washed away and river from being eroded, by putting a protecting net of a grid structure on rocks and planting trees to reduce the speed of flux. CONSTITUTION: A natural bank construction method comprises steps of hardening an earth and sand surface of a bank of a river and then leveling the surface(S100); boring fixing holes in large and small rocks put on the earth and sand surface(S200); interconnecting rocks by forcibly inserting socket parts of connecting members in the fixing holes(S300); placing relatively small gravel to protect the earth and sand surface between rocks interconnected(S400); putting a protecting net of a grid structure on rocks put on the bottom side of the earth and sand surface and adjacent to water of the river(S500); and putting earth and sand in the protecting net and then planting trees to prevent earth and sand from being washed away by making the protecting net entangled in the roots of trees(S600).
