Japanese Patent JP6997737

B2

To provide a sediment retention submerged bank in a low cost constructed using a membrane structure allowing easy installation and maintenance control and capable of directly retaining drift sand by standing by itself on a sea bottom where wave and water flow are wild.SOLUTION: A sediment retention submerged bank in a membrane structure charged and placed on a sea bottom to form the sediment retention submerged bank allowing the entry of drift sand and filling of a filler thereinto is constituted of at least: vertical belt bodies (1) in which two membrane members which allow the passage of sea water but do not allow the passage of drift sand and the filler are erected in the sea while being opposed to each other; floating bodies (2) arranged on each of upper ends of the vertical belt bodies (1); weights (3) arranged on each of lower ends of the vertical belt bodies (1); a plurality of gap retention members (4) connecting between the lower ends of the vertical belt bodies (1) opposite to each other or between the weights (3); upper connecting bodies (5) connecting between upper parts of the vertical belt bodies (1) opposite to each other or between the floating bodies (2) and allowing the passage of the drift sand and the filler; and side belt bodies (6) arranged between side ends on at least one side of the vertical belt bodies (1) opposite to each other.SELECTED DRAWING: Figure 1
