A floating pontoon body to be tied together with at least another pontoon body

Abstract

The invention relates to a floating pontoon body ( 13 ) of concrete, configured to be tied together with at least another pontoon body ( 11,12,13 ) in order to provide a interconnected floating body ( 10 ), where the pontoon body ( 13 ) comprises a deck slab ( 15 ) of concrete and at least down from the deck slab ( 15 ), along the periphery of the deck slab extending vertical walls ( 16,16 ′) of concrete, forming a hollow body, and where said pontoon element ( 13 ) along its side edges is configured with upper and lower pulling ducts intended to receive tensioning cables ( 14 ) or the like, intended to tie together two or more pontoon elements ( 11,12,13 ) both along their upper and lower side edges. At least the pulling ducts extending along the lower edges are configured in such way that it is possible to add on one or more new pontoon elements subsequent to a stage where two or more pontoon elements already are connected, tied together and installed.

       15 . Floating pontoon body of concrete, configured to be tied together with at least another pontoon body in order to form an interconnected floating body, where the pontoon body comprises a deck slab of concrete and vertical walls of concrete extending downwards from the deck slab along the periphery of the deck slab, forming a hollow body, and where said pontoon element long the top and bottom side edges of the vertical walls is configured with upper and lower pulling ducts intended to receive tensioning cables or the like, intended to tie together two or more pontoon elements both along their upper and lower side edges, characterized in that said pulling ducts are terminated at a level above the sea level when the pontoon is floating in a floating condition, the lower pulling ducts at the lower edge of the vertical walls extending in a skewed manner up from the lower side edges of the pontoon body. 
   
   
       16 . Floating pontoon body according to  claim 15 , wherein the pulling ducts have a slightly curved or more or less straight portion extending from their lower portion at one side edge and up to the termination at a level above the sea level. 
   
   
       17 . Floating pontoon body according to  claim 15 , wherein the pulling ducts are terminated in one end wall of the pontoon body. 
   
   
       18 . Floating pontoon body according to  claim 15 , wherein the lower pulling ducts being terminated in the deck slab. 
   
   
       19 . Floating pontoon body according to  claim 15 , wherein the termination for the pulling ducts are arranged at a distance away from the end surface of the pontoon element. 
   
   
       20 . Floating pontoon body according to  claim 15  wherein the pulling ducts extend from said termination at the deck slab to an adjacent end surface of the pontoon element. 
   
   
       21 . Floating pontoon body according to  claim 18 , wherein said terminations of pairs of pulling ducts are arranged in a well in the deck slab. 
   
   
       22 . Floating pontoon body according to  claim 21 , wherein a well is arranged at each side of the deck slab, more or less straight above each side wall wherein the pulling ducts are embedded. 
   
   
       23 . Floating pontoon body according to  claim 21 , wherein the surfaces of the well where the ends of the pulling ducts are terminated, are substantially vertical and having a size adapted to function as support surface for tensioning jacks, intended to be used for tensioning the cables. 
   
   
       24 . Floating pontoon body according to  claim 15 , wherein the termination for each pulling duct at each end walls is provided with a tightening plate, configured in such manner that a watertight connection is established when the cables are tensioned, tying together to adjacent pontoon elements. 
   
   
       25 . Floating pontoon body according to  claim 24 , wherein the plate has a cylindrical shape and wherein the plate is placed inside a conical recess in the end wall of a pontoon element. 
   
   
       26 . Floating breakwater, wherein the breakwater is made up of pontoon bodies according to  claim 15 , wherein the breakwater is made of sections in such way that several pontoon elements are interconnected to form a curved breakwater where the convex side faces the main direction of incoming waves. 
   
   
       27 . Floating breakwater, according to  claim 26 , wherein each pontoon elements have straight side walls, thus forming a straight body. 
   
   
       28 . Floating pontoon body according to  claim 15 , wherein at least one dowel is arranged at an end of an adjacent element, intended to be inserted into a corresponding recess in an adjacent end wall of an adjacent element, so that the pontoon elements are centred relative to each other during the connecting phase.
