CA 2164112

A device for making holes in the ground includes a tubular cutter (1) having an open first end (2) for insertion into the ground, and an opposite, second end from which a guide means (4) extends. A percussion weight (5) is guided for movement along the guide means and is intended to exert a hammering force on the second end of the cutter. Connected to the end of the percussion weight (5) that lies distal from the tubular cutter (1) is a tubular part (8) which is mounted for axial movement along the guide means (4) and which carries a handle (7) for maneuvering of the percussion weight. The cutter (1) and associated guide means (4) on the one hand and the percussion weight (5) with associated tubular part (8) carrying the handle (7) on the other hand can be locked together releasably against axial movement and are non-rotatable, or are also releasably locked against rotational movement.

Un dispositif de perçage de trous dans le sol comprend une lame tubulaire (1) présentant une première extrémité ouverte (2) destinée à être insérée dans le sol, ainsi qu'une seconde extrémité opposée à partir de laquelle s'étend un moyend de guidage (4). Un poids de percussion (5) est guidé pour effectuer un mouvement le long du moyen de guidage, et il est destiné à exercer une force de martelage sur la seconde extrémité de la lame. Une partie tubulaire (8) reliée à l'extrémité distale, du poids de percussion (5) à partir de la lame tubulaire (8), est montée de manière à effectuer un mouvement axial le long du moyen de guidage (4), ladite partie portant un manche (7) destiné à manoeuvrer le poids de percussion. La lame (1) ainsi que le moyen de guidage associé (4) d'une part et le poids de percussion (5) avec la partie tubulaire associée (8) portant le manche (7) d'autre part peuvent être verrouillés ensemble de manière libérable contre le mouvement axial et sont non rotatifs, ou ils sont également verrouillés de manière libérable contre un mouvement rotatif.
