Session: Retaining Walls

ABSTRACT: With urban growth all around the world, it is observed a demand for big constructions with large excavations, such as subways, tunnels and underground garages. The real estate valuation in urban areas influences the architectural style and creates the need of executing underground basements until the boundary of the properties. Due to interferences and limitations imposed by neighboring constructions, executive retaining processes become important for its appropriated performance. Thus, in big cities, it is necessary to find construction methods alternatives which have in its conception some competitive advantage over others. The aim of this work is to present and standardize an execution method of retaining walls, the rectangular hand excavated shaft, popularly called "big rectangular", which was first used in the city of Belo Horizonte, in Minas Gerais, Brazil, and that is now applied all over the country. PRESENTACIONES TECNICAS Con el crecimiento urbano en todo el mundo, se observa una demanda de grandes construcciones con grandes excavaciones, tales como el metro, túneles y garajes subterráneas. La valoración de bienes inmuebles en las zonas urbanas influye en el estilo arquitectónico y crea la necesidad de la ejecución de basis subterráneas hasta el límite de las propiedades. Debido a las interferencias y limitaciones impuestas por las construcciones vecinas, los procesos ejecutivos de contención se hacen importantes para su el rendimiento apropiado. De esa manera, en las grandes ciudades, es necesario buscar alternativas de métodos de construcción que tienen en su concepción alguna ventaja competitiva sobre los demás. El objetivo de este trabajo es el de presentar y estandarizar un método de ejecución de muros de contención, la mano rectangular excavada basis, popularmente llamados "grande rectangular", que fue utilizado por primera vez en la ciudad de Belo Horizonte, en Minas Gerais, Brazil, y que ahora se aplica por todo el país.
