SPACERS OF IMMERED MARINE STRUCTURES AND METHODS OF REPAIRING SUCH SPACERS

摘要

Submerged marine structures of the tubular trellis type serving as a platform support at sea. /P P The spacers made in the form of hollow bars 3 are provided at their two ends with two nozzles 4 and 5 fitted with protective covers 7, one of the tappings 5 being fitted with a non-return valve 8. /P P To check the tightness of the bars 3, the tapping 5 provided with the valve 8 is connected to a source of compressed air and observed the release of bubbles or a drop in pressure. /P P To repair in the event of damage, cement is injected through one of the nozzles 5 with draining of the excess through the second nozzle 4, so as to fill the inside of the bar. /P P The injection of cement makes it possible to restore the resistance of the bar.
