MODULAR SYSTEMS FOR SHORE PROTECTION

MODULAR CONSTRUCTION, AS IT IS USED IN PROTECTING THE SHORE BY CHECKING EROSION AND PROTECTING BEACHES FROM WAVE DAMAGE, IS DISCUSSED WITH RESPECT TO INTERLOCKING REVETMENTS, REVETMENT MATTRESSES, PRECAST PERMEABLE GROIN, PERFORATED BREAKWATER, AND POLYPADS. INTERLOCKING REVETMENTS CONSIST OF PRECAST CONCRETE SECTIONS THAT INTERLOCK IN NUMEROUS SHAPES AND SIZES WHEN PLACED ON AN EMBANKMENT. REVETMENT MATTRESSES ARE USUALLY OF NYLON, SECTIONALIZED AND THEN FILLED WITH A FINE AGGREGATE CONCRETE OR MORTAR. THE PRECAST PERMEABLE GROIN--A 30 X 6 X 5' PERFORATED PRECAST CONCRETE BOX WITH 6" REINFORCED CONCRETE WALLS AND PERFORATIONS OVER THE SIDE WALLS--IS DESIGNED TO RETARD ONLY A SMALL PERCENTAGE OF THE LITTORAL DRIFT. A PERFORATED BREAKWATER STRUCTURE--SERVING AS A WHARF TOO--UTILIZED THE HOLES ON THE SEAWARD SIDE OF THE BREAKWATER TO DISSIPATE WAVE ENERGY. POLYPADS ARE NOTHING MORE THAN LARGE PRECAST CONCRETE STRUCTURES USUALLY INTERLOCKING IN A VARIETY OF SHAPES DESIGNED FOR THE PURPOSE OF PROTECTING THE SHORE AND USED WHEREVER THERE IS HEAVY WAVE ACTION OR IN BREAKWATERS.
