COFFERDAM CONSTRUCTION METHOD USING THE LARGE CALIBER STEEL PIPE FOR THE STRUCTURES CONSTRUCTED OVER THE WATER

摘要

drought underwater film structures using large diameter steel pipe construction method of the invention is a plurality of sheet pile driving and construction files the release of existing methods and is drought drought film membrane Driven by placing in the hands of one single large diameter steel pipe used in the drought just a pre-production in other land use large-diameter steel pipe work installation is possible airborne and significantly reduce air and azeotropic Dramatically can save existing files during construction essentially required sheet files that were being made guides becomes unnecessary operation is simple, a single drought can just use large-diameter steel pipe in the order becomes a perfect tightness is ensured and, after completion of construction as the invention more economical to reuse the recovered while in the drought just use large-diameter steel pipe is another scene in the film drought underwater structures using large diameter steel pipe of the present invention to this construction method is a single layer of drought on land previously made use of large diameter steel pipe The steps for installing the pile driving position in the construction of water: the step of installing the drought membrane tube containing the drought just use large-diameter steel pipe and drain the water in the pipe to the surface membrane drought; Cutting the predetermined length of said upper end drought membrane using a large diameter steel pipe and the construction of the award based structure; And steps to dismantle the tube film the drought; drought film provides a method of underwater structures constructed using large diameter steel pipe that contains the
