Ces tubes ne seront pas soudés mais

Ces tubes ne seront pas soudés mais manchonnés pour obtenir une longueur totale égale à celle du pieu ou de la barrette augmentée d'une longueur de 50 cm de dépassement extérieur pour permettre une intervention aisée le jour de l'essai. Ces tubes sont destinés à être remplis d'eau pour le contrôle sonique.
Ils seront, au moment de leur implantation sur la cage d'armature, soigneusement obturés à leur extrémité inférieure par un bouchon plastique étanche. A leur extrémité supérieure, les tubes seront obturés soigneusement par un bouchon métallique vissé

These tubes are not welded but coupled to obtain a total length equal to the pile or augmented Strip with a length of 50 cm of external overflow to allow an easy intervention the day of the test. These tubes are designed to be filled with water for the Sonic control.They will be at the time of their establishment on the cage frame, carefully sealed at their lower end by a sealed plastic plug. At their upper end, the tubes will be sealed carefully by a metal screw

These tubes will not be welded but sleeved to obtain a total length equal to that of the increased pile or strip of a length of 50 cm outside pass for easy action on the day of the test. These tubes are designed to be filled with water to the sonic control.
They will, at the time of implantation in the reinforcing cage, carefully closed at their lower end by a sealed plastic cap. At their upper end, the tubes are carefully closed by a metal screw cap
