Abstract

Un dispositivo (1) para perforar un eje (2) en un sustrato (3) que consiste en roca, barro y/o materiales relacionados, que comprende un tubo (4) de revestimiento y medios para disponer el tubo (4) de revestimiento en el sustrato (3); y más medios (8,10) de perforación que pueden ser bajados en el tubo (4) de revestimiento y están provistos de una cabeza (8) de perforación con herramientas de corte, y medios (7a) para establecer los medios (8, 10) de perforación en rotación; donde el tubo (4) de revestimiento comprende una primera y una segunda partes (4b) que son desplazables telescópicamente en relación entre ellas a lo largo de un eje común, que se extiende en una dirección longitudinal de ambas partes, entre una posición extendida, en la cual las partes están acopladas con medios (5, 6) de acoplamiento y una posición retraída.A device (1) for drilling a shaft (2) in a substrate (3) consisting of rock, mud and / or related materials, comprising a coating tube (4) and means for arranging the coating tube (4) in the substrate (3); and more drilling means (8,10) that can be lowered into the casing tube (4) and are provided with a drilling head (8) with cutting tools, and means (7a) for establishing the means (8, 10) rotating drilling; where the casing tube (4) comprises a first and a second part (4b) that are telescopically movable in relation to each other along a common axis, which extends in a longitudinal direction of both parts, between an extended position, in which the parts are coupled with coupling means (5, 6) and a retracted position.
