PERMEABLE WAVE SUPPRESSING FACILITY Russian patent published in 2003 - IPC

FIELD: hydraulic facilities; protection of water basins, banks and engineering facilities against wave action. SUBSTANCE: facility has fill of shaped blocks or stone kept in framework which is filled and immersed in water end is provided with side walls made in form of grates with open upper and lower end faces; it is also provided with upper prism made from the same fill with banks which are not secured. Framework is mounted on supports on bottom and its upper open end face is located above irregularities of bottom at height ensuring formation of lower prism of fill at the following ratio: , where α is distance between line of intersection of front bank (back draft of wave) or rear bank (at landwash) with bottom and point of intersection of line of resultant of loads on bottom, m and "b" is width of lower prism over bottom, m. Clearance between members of grates of side walls of framework are lesser than cross section of shaped blocks or stone of fill. EFFECT: simplified procedure; low cost; enhanced efficiency and reliability. 2 cl, 2 dwg
