SHEET-PILE WALL Russian patent published in 2002 - IPC

FIELD: water-development works, applicable for construction of sea-walls of wharfs and embankments with the use of steel tubular piles, as well as for erection of relieving walls of various purpose. SUBSTANCE: sheet-pile wall has piles with sheet-pile bulges and sheet-pile cut-offs rigidly secured on their surfaces, each of them is made of two profiled members positioned in a spaced relation to one another and joined to the other stiffening rib with formation of a keyway for placement of the pile bulge in it. The sheet-pile cut-offs are combined in pairs in closing rod-shaped members having two longitudinal keyways each and installed in the wall between the piles. Each closing rod-shaped member has a cross-section area that is considerably smaller than the cross-section area of the pile, and is welded of two channels, whose flanges face each other and are located in a spaced relation to each other, and has at least one stiffening rib placed between the channels. The closing member may have two stiffening ribs, which are made in gaps between the channel flanges. EFFECT: reduced specific quantity of metal per structure and complication of erection of the sheet-pile wall at the required stiffness of the closing cut-offs and prevention of opening of the sheet-pile cut-offs, as well reduced labour content and accelerated manufacture of tubular piles. 2 cl, 4 dwg
