Abstract

Un aparato para apoyar en tierra que comprende una primera porcion que comprende medios de friccion alargados para anclar de manera sustancial contempla el aparato en un barreno formado dentro de un cuerpo de roca, una segunda porcion dispuesta sustancialmente hacia el extremo frontal del aparato y que empalma la primera porcion, un medio de anclaje localizado dispuesto en una union entre la primera porcion y la segunda porcion y un mecanismo de fluencia. En uso, un movimiento del cuerpo de roca engancha el mecanismo de fluencia mediante el cual gobierna el movimiento del cuerpo de rocaA ground bearing apparatus comprising a first portion comprising elongated friction means for substantially anchoring contemplates the apparatus in a hole formed within a body of rock, a second portion disposed substantially towards the front end of the apparatus and connecting the first portion, a localized anchoring means arranged at a junction between the first portion and the second portion, and a creep mechanism. In use, a movement of the rock body engages the creep mechanism by which it governs the movement of the rock body.
