Method for constructing bank protection in soft ground of river-mouth or the seaside

摘要

PURPOSE: A construction method for a revetment on the soft ground at the river mouth or the seaside is provided to construct a stabilized structure simply and economically. CONSTITUTION: The construction method for a revetment on the soft ground at the river mouth or the seaside comprises the steps of: driving many pile members(401) in two lines on the soft ground at the river mouth or the seaside; cutting off the upper end of the pile member(401) to the appointed height; fastening couplers(402) to the upper ends of the opposite two pile members(401) for dispersing bearing force evenly and keeping flatness; placing precast footing blocks(110) on the pile members to connect adjacent blocks mutually using a connector; paving ripraps(403) on all sides of pile members(401) and tamping to be leveled to the upper side of the footing block(110) placed on the pile member(401); piling up straight blocks(210) on the footing blocks(110) primarily; spreading a radial sheet(404) for landslide prevention on the backside of the primary structure and the upper side of a leveled riprap part behind the pile member(401), then placing soil(405) on the backside of the radial sheet(404); and building a revetment by piling up blocks on the primary structure to the appointed height, spreading a radial sheet(404) on the backside of the structure and placing soil(405) on the backside of the radial sheet(404).
