<p>The prefabricated beam (L,T,L') stabilises a pipe (C) found at the bottom of the sea that is exposed to the swell and currents. The beam comprises two blocks of rigid ballasting (L,L') mounted at opposite ends of a cross-piece (T). The blocks are jointed to the cross-piece so that their positions can vary independently, each block having a frontal face (1,L',1) to contact a face of the pipe. The cross-piece is held by the blocks on the pipe, and the blocks are simultaneously in contact with the sea bed and the pipe.</p> |
