RIVER BANK PROTECTION STRUCTURE USING POLYURETHANE COATING POROUS AGGREGATE AND MAT, AND METHOD FOR CONSTRUCTING THEREOF

摘要

The present invention relates to a revetment slope protecting structure using a fiber mat and a porous vegetation aggregate coated with vegetable polyurethane and a construction method thereof. The revetment slope protecting structure is installed on a slope of a revetment to efficiently deteriorate flow of running water through a porous structure without discharging toxicity to a river, wherein the protecting structure includes a porous vegetation aggregate bound by a vegetable polyurethane which is a nontoxic binding material, a filling soil and a fiber mat installed on the porous vegetation aggregate. The revetment slope protecting structure can make environment-friendly revetment by inducing soil to be naturally deposited and providing a biotope so that plants easily take root and grow through multiple pores and various living things live.
