BLOCK FOR QUAY AND REVETMENT

摘要

PURPOSE: A block for a quay and a revetment is provided, which absorbs the energy from various external pressures such as a wave and reduces a reflected wave effectively, thereby protecting a quay and a revetment and possibly bringing a ship alongside the pier and securing a workshop. CONSTITUTION: A block for a quay and a revetment comprises the steps of; forming a hollow section (11) on the upper and lower sides; placing an upper plate (20), having a projection (21) and a hook (22), and a lower plate having a long groove (31); forming an incline (41) on the latter part of a joint body; forming a perpendicular body (40) connected to a hook (43) in a hollow section (42) of an upper side.
