PURPOSE:To shorten the construction period of steel sheet pile cells by making their assembly easier by providing a means whose buoyancy can be easily adjusted by charging of water. CONSTITUTION:A floater pontoon 1 whose buoyancy is freely adjusted by charging of water, a weight 3 to be hung down from the floater pontoon 1 by a wire 2, and a guide frame 5 to be provided on the side of the floater pontoon for assembling prefabricated steel sheet pile cells are provided. By the system in which the steel sheet pile cells 6 can be assembled under the guidance of the guide frame 5, the assembly of the steel sheet pile cells 6 can be made easier because the position of the floater pontoon on the seabed is not almost varied even by the variations in tidal levels. |
