Abstract

Un estabilizador de roca por fricción mejorado para inserción forzada del mismo en un taladro de tamaño insuficiente en una estructura, tal como un techo o una pared de un pozo o túnel de mina o similar, para estabilizar la estructura, comprendiendo dicho estabilizador un cuerpo alargado que, en sección transversal, es sustancialmente anular, y que tiene medios que se extienden en general longitudinalmente, desde un extremo de dicho cuerpo en al menos la mitad de la longitud del mismo, que responden a la compresión circunferencial de dicho cuerpo, procedente de tal inserción forzada del mismo al interior de dicho taladro de la estructura, para obligar a al menos una porción de dicho cuerpo a adoptar una periferia disminuida a fin de acomodarse a tal inserción forzada, y para obligar a dicho cuerpo a aplicarse con fricción a la superficie de dicho taladro de la estructura a fin de estabilizar la estructura, en el que la mejora comprende medios hechos enterizos con dicho extremo de dicho cuerpo para reforzar dicho extremo a fin de aceptar las fuerzas de inserción en el taladro dirigidas a dicho estabilizador y para fijar una placa de soporte contra la estructura.
