FSP sheet piles can be produced in Japan, Korea and China. And they are used in many types of temporary works and permanent structures. FSP type ⅠA,Ⅱ, IIA, Ⅲ, ⅢA, Ⅳ are 400mm wide sections. FSP typeⅤL, ⅥL, ⅡW, ⅢW, ⅣW. are wide sections. Mills can be found in Nippon and Fuji. It is the. Seawalls are shore-parallel structures designed to protect upland installations such as houses and roads, port facilities or artificially filled land areas. The sections are designed to provide the maximum strength and durability at the lowest possible weight consistent with good driving qualities.
The term FSP is sometimes used interchangeably with seawall; however, structures intended as docks, wharves, or boat landings are almost always referred to as bulkhead structures. Sheet piles are one of the most common types of earth retention structures.
The existing seabed was between approximately -2.0 EL to +1.0 EL in the vicinity of the proposed wall. FSP sheet pile has reclaimed the area to approximately +3.0 EL. Fill material is dense to very dense sandy gravel with cobbles and boulders. The design of the section interlocks facilitates pitching and driving and results.
