DOUBLE SHEET PILE TYPE PORT CIVIL ENGINEERING STRUCTURE

PROBLEM TO BE SOLVED: To provide a double sheet pile type port civil engineering structure capable of preventing a solidified filling material from slipping against the sheet piles and increasing the composite effect of the sheet piles and the filling material and increasing the deformation resistance against waves, water pressure, and earth pressure to enhance the rigidity of the structure. SOLUTION: Two rows of steel sheet piles or steel pipe sheet piles 1 are driven into the submarine ground 2 parallel to each other. Solidifying earth 4 is filled in between mutual sheet piles to form an embankment. A top slab 5 formed to have a width W larger than 1/10 of the embankment height H is installed on the top of the two rows of steel sheet piles or steel pipe sheet piles.
