METHOD AND DEVICE FOR SAND BEACH WASHING-IN Russian patent published in 2006 - IPC E02B3/04 

FIELD: hydraulic building, particularly to prevent sea and river beach erosion with incoming waves by sand beach washing-in.

SUBSTANCE: method involves installing ground retaining members on upstream slope so that ground retaining members are located along shore line; fixing the retaining members by means of flexible ties secured in ground. Ground retaining members are made of plates connected with each other, extending at an angle one to another and bendable in vertical plane. The retaining members may be moved in vertical direction under the action of incoming wave and pressed to ground by reverse wave, which results in sump ponds creation and provides drainage behind each ground retaining member. After necessary ground amount accumulation ground retaining members are serially moved towards water surface. Device for above method realization comprises several rows of ground retaining members connected to fixing ropes provided with anchors. Each ground retaining member is made of plates connected with each other so that an angle in defined in-between. The plates are formed of separate sections with quick-releasable connections and are bendable in vertical plane. Bulk density of plate material is equal or greater than that of water.

EFFECT: increased efficiency.
