AUXILIARY DAM AND COMPOSITION STRUCTURE FOR ECOLOGY LAKE USING THE SAME

摘要

The present invention provides an auxiliary dam (300) and a composition structure of an ecological lake using the same. The auxiliary dam (300) installed in the river comprises: a plurality of protrusion members (310) protruding from a central part (301) in an upward direction to interrupt impurities from flowing water, in addition to forming the central part (301) of the auxiliary dam (300) in a depression structure such that the flowing water overflows; and a network-structured film member (320) formed on an edge (302) of the dam (300), and formed to be automatically spread in an upward direction when a river stage rises. When the river stage rises, a function of interrupting the impurities is improved, and the impurities and wastes are automatically removed to prevent concerns about a loss of function of the auxiliary dam, and to secure clean water quality for the ecological lake.
