ELEMENTO ALONGADO PARA ANCORAGEM,PROCESSO DE ANCORAGEM EM PONTO E CORPO |
摘要 |
An anchor element is provided with a body of bonded particulate material, e.g. a sleeve of silicate bonded sands. The element is received in a borehole with the sleeve adjacent the blind end. When a compressive force is applied between the ends of the body, the particles move closer together to form an annulus of compacted particulate material bridging the element and the wall of the borehole. |
