French term or phrase: sabot de cimentation à bille anti-retour
Une étanchéité parfaite jusqu'à la cote déterminée devra être assurée pour tout nouveau forage, puits ou piézomètre destiné à capter la nappe. Cette étanchéité sera obtenue par la mise en place d'un tubage plein en acier de la surface du sol jusqu'à cette cote, avec cimentation annulaire sous pression (injection d'un coulis de ciment par le fond par l'intermédiaire d'un sabot de cimentation à bille anti-retour).

Explanation:
The 'ball' part of the term is sometimes referred to and at other times is left out of the description. 'Sabot de cimentation' is also called 'cement shoe' but is more commonly referred to as 'float shoe' see page 67 of

http://infoterre.brgm.fr/rapports/RP-58793-FR.pdf

This from Schlumberger

"float shoe - A rounded profile component attached to the downhole end of a casing string. An integral check valve in the float shoe prevents reverse flow, or U-tubing, of cement slurry from the annulus into the casing or flow of wellbore fluids into the casing string as it is run. "

https://www.glossary.oilfield.slb.com/en/Terms/f/float_shoe....

It also has a diagram showing the check valve which is basically a ball that seats itself in order to stop the back flow of the cement.

This from Haliburton -

"The float shoe contains a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing."

A more detailed diagram is shown of the whole setup here.

You can see how the ball will head downwards when the downward pressure is greater and still allows downward flow though the system. When the backpressure upwards is higher, then the ball is forced upwards and shuts off the upper parts and stopping any upward, backwards flow.
