Abstract

La invencion proporciona un perno de roca anclado en el extremo que incluye un cuerpo cilindrico alargado que se extiende longitudinalmente entre un extremo proximal y un extremo distal y un taco en el extremo distal, taco que es mas grande diametralmente que el cuerpo cilindrico, es al menos parcialmente de seccion decreciente, decreciendo la seccion hacia el extremo proximal, y se forma de manera solidaria en el cuerpoThe invention provides an end anchored rock bolt that includes an elongated cylindrical body extending longitudinally between a proximal end and a distal end and a dowel at the distal end, which dowel is diametrically larger than the cylindrical body, is al less partially tapered in section, the section decreasing towards the proximal end, and is formed integrally in the body
