Abstract

Se provee un trépano rotativo para perforar un pozo de sondeo en una formacion de suelo. El trépano comprende numerosos elementos cortantesubicados para realizar numerosos cortes separados radialmente, sustancialmente circulares, en el fondo delpozo de sondeo, incluyendo los elementos cortantespor lo menos un elemento cortante/de cizallamiento, estando ubicado cada elemento cortante/de cizallamiento de manera de cortar en el fondo del pozode sondeo en un intervalo angular detrás de otro dedich os elementos cortantes. Se define un cuerpo de material de roca entre las trayectorias de loscortes creados por el elemento cortante/de cizallamiento y dicho otro elemento cortante. El elemento cortante/de cizallamiento está provisto demediospara ci zallar dicho cuerpo de material de roca en la direccion del corte creado por dicho otro elemento cortante.A rotating press is provided to drill a borehole in a soil formation. The trephine comprises numerous cutting elements located to make numerous radially separated, substantially circular cuts, at the bottom of the borehole, including the cutting elements for at least one cutting / shearing element, each cutting / shearing element being located so as to cut in the bottom of the borehole at an angular interval behind another of the sharp elements. A body of rock material is defined between the paths of the cuts created by the shear / shear element and said other shear element. The shear / shear element is provided with means to shear said rock material body in the direction of the cut created by said other shear element.
