Summary:Downhole tool assembly (10) for mounting to a core barrel assembly (12) including a core tube (14) and a pair of split tubes (16). The downhole tool assembly (10) includes a downhole tool (18) and at least one sleeve (20) dimensioned to slidingly engage the split tubes (16) to inhibit radial movement of the split tubes (16) and receive and retain the downhole tool (18) coaxially with the core tube (14). Core ejection pistons (72), and methods for extracting a core from bedrock are also disclosed. A housing assembly (120) for a downhole tool, downhole assemblies (180, 200), and methods of assembling such assemblies are also disclosed. L'invention concerne un ensemble outil de fond de trou (10) destiné à être monté sur un ensemble tube carottier (12) comprenant un tube de carottage (14) et une paire de tubes fendus (16). L'ensemble outil de fond de trou (10) comprend un outil de fond de trou (18) et au moins un manchon (20) dimensionné pour venir en prise de manière coulissante avec les tubes fendus (16) pour empêcher un mouvement radial des tubes fendus (16) et recevoir et retenir l'outil de fond de trou (18) coaxialement au tube de carottage (14). L'invention concerne également des pistons d'éjection de carotte (72) et des procédés d'extraction d'une carotte d'un substratum rocheux. L'invention concerne aussi un ensemble enveloppe (120) pour un outil de fond de trou, des ensembles fond de trou (180, 200) et des procédés d'assemblage de tels ensembles.
