Abstract

<p>UN PERNO DE ROCA HUECO DEFORMABLE, AUTOPERFORANTE, LOCALMENTE ANCLACO TIENE UNO O MÁS ANCLAJES LOCALES INTERMEDIOS 1 6A, DONDE CADA UNO DE ELLOS ESTÁ ACOMPAÑADO POR DOS SEGMENTOS DE VÁSTAGO RELATIVAMENTE ALARGABLES 1 4A, 1413. DESPUÉS DE SUMINISTRADA LA LECHADA A TRAVÉS DEL INTERIOR HUECO DEL PERNO DE ROCA, MIENTRAS EL PERNO DE ROCA SE ENCUENTRA EN EL BARRENO PERFORADO, CADA ANCLAJE 16AFIJA EL PERNO EN LA FORMACIÓN ROCOSA, MIENTRAS QUE LOS SEGMENTOS DE VÁSTAGO LISOS 14A, 1413 SE PUEDEN DEFORMAR E INCLUSO DESFIGURAR PARA ACOMODAR LA FRACTURA DE LA ROCA. LOS ANCLAJES LOCALES PUEDEN TENER UNA EXTENSIÓN RELATIVAMENTE CORTA EN COMPARACIÓN CON LOS SEGMENTOS DE VÁSTAGO. UNO O MÁS DE LOS ANCLAJES INTERMEDIOS 16A PODRIAN FORMARSE A TRAVÉS DE UN ACOPLADOR QUE CONECTA LAS SECCIONES DE PERNO ADYACENTES Y/O A TRAVÉS DE LA CONFORMACIÓN DEL PERNO Y/O MEDIANTE LA ENTREGA DE UN ANCLAJE EXTERNO. EL EXTREMO MÁS PROFUNDO DEL PERNO DE ROCA PUEDE FORMARSE A TRAVÉS DE UNA BROCA O CONTENER UNA BROCA. ESTA BROCA PUEDE TENER LA FUNCIÓN DOBLE DE PERFORAR EL BARRENO Y SERVIR CORNO EL ANCLAJE MÁS PROFUNDO DEL PERNO.</p>
