Accueil > Maintenance of geotextile tubes

Total inspection

The frequency of inspections is to be defined according to the sites and the period of the year. Reconnaissance consists of carrying out an underwater inspection of the entire dike.

DURING THIS INSPECTION, THE FOLLOWING IS NOTED

  • The general state of the dike
  • The presence of macro waste
  • Sinking / loosening of ballast tubes and mats
  • Burying of deadmen
  • The condition of the buoys, eye members, chains and deadmen
  • Moving an element of the structure
  • The presence of rips (malicious act, impact of ships, etc.)
  • The state of attachments and closures of vents
  • The state of the various marking elements
  • The presence of excess mussels

A photographic report is established by specifying the positioning on the plan of all the observed damage that could affect the stability of the structure.

Cleaning of the structure or the periphery

The cleaning of the periphery of the structure consists of removing all the macro waste which can cause damage to the structure.

The different elements

  • Pieces of wood
  • Metal bars
  • Sharp plastics

The operation consists of cleaning packets of mussels glued to the straps, the geoports and also to the top of the geotextile tubes.

The cleaning of geoports consists of removing concretions and fauna and flora that have developed in large numbers, in order to maintain and optimise safety.

 

Cleaning is done with care so as not to damage the fabric of the tubes.
