Quay wall structure

Abstract

A gravity-type quay wall comprising a rubble base stage ( 3 ) extending from the sea bottom. A lower part ( 1 a ) is constructed on the rubble base stage ( 3 ) by stacking cell block units ( 4 ) wherein each of the cell block units ( 4 ) have four walls defining a vacant space therein for filling with rubble ( 5 ). Two of the walls of the cell block units ( 4 ) are side walls ( 6,6 a ), each having one of a female key ( 13 ) or a male key ( 14 ) for mating with adjacent cell block units ( 4 ). In an upper part of a top staged cell block unit ( 4 a ) is a depressed portion ( 7 ). An L-shaped shelf-style middle part ( 1 b ) is settled on a top surface of the rubble ( 5 ) of the lower part ( 1 a ) wherein the rubble ( 5 ) is filled halfway in the depressed portion ( 7 ). An upper part ( 1 c ) is settled on the middle part ( 1 b ) with the same length and width thereof.
