Document Type and Number:
Japanese Patent JP5296918
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To allow a water-intake time form in a normal state and a water non-intake time form of a gutter for water intake in a flood or when sediment and the like are accumulated on a bottom to be easily switched, and to enable inflow of fallen leaves to be prevented and removal of pebbles and fine-grained soil from the gutter for water intake to be surely performed.SOLUTION: An intake mechanism of a check dam can perform water intake by a gutter for water intake, can avoid trouble due to flood or accumulation of sediment and the like by deforming the gutter for water intake in a flood or when sediment and the like are accumulated on a bottom of the gutter for water intake, and restores the gutter for water intake to the original water intake time form to resume water intake. The deformable gutter for water intake is formed of: a dust removal screen of which one end is held on the top end of a notch of the check dam; a side plate of which one end is connected to the other end of the dust removal screen; a bottom plate of which one end is connected to a deformable section of the other end of the side plate; and a rotary arm of which one end is connected to the bottom plate and of which other end is connected to a wall surface of the check dam. Switching of the form of the gutter for water intake is performed by operating the rotary arm.
