Recalce en condiciones de emergencia: 40 viviendas cercanas al río Guadalquivir, España

Abstract

RESUMENLas intervenciones en edificaciones en circunstancias de emergencia, y en concreto los recalces de cimentaciones son circunstancias poco documentadas dentro de la rehabilitación. Esto se debe, en parte, a la complejidad técnica y la tendencia a evitar hacer públicos datos que puedan conllevar responsabilidades derivadas.En el artículo se expone el recalce de un edificio de 40 viviendas en Sevilla, cercanas al Río Guadalquivir, afectado por la construcción contigua de un aparcamiento subterráneo. También se establece una comparativa entre tres técnicas consideradas, y finalmente, se explica, técnica y económicamente el método de micropilotes adoptado. Éste se elige, entre otras razones, debido a la calidad del suelo. De la experiencia se ha podido inferir que el éxito de la intervención se ha conseguido debido a tres factores: la organización de la obra, el estudio de los plazos y la implicación de los propietarios afectados. ABSTRACTThe reconstruction works in buildings under emergency conditions and, more specifically, the foundation repaired has been poorly documented in rehabilitation. This is due, in some extend, to not make public this type of reports mainly due to its complexity and possible related responsibilities.In the present article, the foundation recovery of a building with 40 flats, located in Seville, Spain, near the Guadalquivir River which was affected by the excavations of an underground parking lot are explained. Three different techniques are considered and compared; finally, the micropile solution implemented is explained, technically and economically. Micropiles were chosen due to, among other aspects, the soil quality. The experience gives rise to three main factors in a successful work: the organization, the scheduling and the neighbors' participation in the work programming.

Evaluating Environmental Impact in Foundations and Structures through Disaggregated Models: Towards the Decarbonisation of the Construction Sector

“…In this paper, the University of Seville aims to disseminate to the scientific community the research done during the construction works carried out in the practical case, just as it did with the foundation repairs in 40 homes in the "RENFE" neighbourhood, whose foundations were affected by the adjacent excavation of the new Faculty of Medicine. A standard model has been created by this research for its use in similar situations from the perspective of sustainability [42].…”
