Double-T-beam for construction of combination sheet pile walls

Abstract

A double-T-beam for the construction of a combination sheet pile wall from numerous elements that can be driven into the ground, such as beams, sheet piles, etc., whereby the double-T-beam exhibits in its cross-section two T-bars, and one connecting web that connects said T-bars and forms the T-down-stroke. The free longitudinal edges of the double-T-beam, which are located on one side of the connecting web in one plane parallel to the connecting web, are designed as analogous connecting elements of the type round claw or round knob for directly connecting additional sheet pile wall elements with corresponding connecting elements.

       9 . In a double-T-beam for the construction of a combination sheet pile wall from numerous elements that can be driven into the ground, whereby the double-T-beam exhibits in its cross-section two T-bars and one connecting web that connects said T-bars and forms the T-down-stroke, the improvement wherein free longitudinal edges of the double-T-beam, which are located on one side of the connecting web in one plane parallel to the connecting web, are configured as analogous connecting elements of a type selected from the group consisting of round claw and round knob for directly connecting additional sheet pile wall elements with corresponding connecting elements.  
   
   
       10 . The double-T-beam set forth in  claim 9 , wherein the double-T-beam exhibits, on one side of the connecting web, connecting elements of the type round claw and, on an opposite side of the connecting web, connecting elements of the type round knob.  
   
   
       11 . The double-T-beam set forth in  claim 10 , wherein, for use in constructing a sheet pile wall, two sheet piles with a Z-shaped cross-section are inserted between two double-T-beams each, wherein each said sheet pile exhibits at its one longitudinal edge a connecting element of the type round claw and at its other longitudinal edge a connecting element of the type round knob, and wherein said sheet piles are connected at their center via their corresponding connecting elements, whereby the connecting elements at the two longitudinal edges of the sheet pile pair engage in the corresponding connecting elements of two adjacent double-T-beams.  
   
   
       12 . The double-T-beam set forth in  claim 11 , wherein, at the sheet pile wall, locks that are formed by the connection of the corresponding connecting elements at the double-T-beams are located in one plane.  
   
   
       13 . The double-T-beam set forth in  claim 9 , wherein the double-T-beam exhibits at its longitudinal edges connecting elements of the type round knob on both sides of the connecting web.  
   
   
       14 . The double-T-beam as set forth in  claim 13 , wherein; for use in constructing a sheet pile wall, two sheet piles with a Z-shaped cross-section are inserted between two double-T-beams each, wherein each said sheet pile exhibits at one longitudinal edge a connecting element of the type round claw and at its other longitudinal edge a connecting element of the type round knob, and wherein said sheet piles are connected at their center via their corresponding connecting elements, and whereby the connecting element of the type round claw engages on the one longitudinal side of the sheet piles that are connected to one another in the connecting element of the one double-T-beam of the type round knob and the connecting element of the type round knob engages on the other longitudinal side of the sheet piles that are connected to one another with the connecting element of the type round knob of the second double-T-beam via a double-C-claw.  
   
   
       15 . The double-T-beam as set forth in  claim 14 , wherein, at the sheet pile wall, locks that are formed through connecting the corresponding connecting elements at at least one of the double-T-beam and the double-C-claw, respectively, are located in one plane.  
   
   
       16 . The double-T-beam as set forth in  claim 9 , wherein, for the direct connection to the double-T-beam, sheet piles exhibit at their one longitudinal edge connecting elements of the type round claw and at their other longitudinal edge connecting elements of the type round knob, wherein the sheet piles between the two connecting elements exhibit three web sections which together form a Z-shaped cross-section, wherein the connecting elements that follow said web sections stretch parallel to one another and point outward from the connecting elements, and wherein the center Z-section connects the ends of the web sections.
