PREFABRICATION TYPE BLOCK FOR CONSTRUCTED WETLAND, CONSTRUCTED WETLAND USING THE BLOCK, AND MANUFACTURING METHOD OF THE CONSTRUCTED WETLAND

摘要

PURPOSE: A prefabrication type block for constructed wetland and a manufacturing method of constructed wetland structure are provided to prevent ecosystem destruction due to corrosion and rust stain outflow of reinforcing rods. CONSTITUTION: A constructed wetland structure(200) includes at least two blocks(12,18) assembled in one body. The constructed wetland structure is formed by assembling a plurality of first blocks and second blocks. The first block includes a first bottom part and a first side wall(16). A first opening part(121) is formed on a side of the first side wall. A second opening part(122) is formed on a location which is lower than a part of the first side wall.
