El recalce con micropilotes para la conservación de un muro de tierra compactada realizado con la técnica del tapial

Abstract

In this paper, the discovery of a peri-urban work of hydRaúlic engineering is presented. A wall-dike was found during the excavation for an underground public parking on the left bank of the Genil River in Granada city (Spain). Those consist in a compacted earth wall (using "Tapial-technic") of 55 m length with three cutwaters. Three different construction methodologies were detected in the wall-dike: monolithic-wall (s. XI), royal wall (s. XII-XIII) and contemporary reparation (s. XIX). These elements were conserved in the original position with the help of the micropiles technique. The consolidation stages were as follows: vertical micropiles in its perimeter; horizontals micropiles in the base of the wall; brace beam and thought bolts with Gewi rod. After the digging, also, laminated metal sections with an "L" were welded together and to vertical micropiles. That element is fully integrated with both underground construction and its environment, "Paseo del Violon".
