Resumen
Por medio de la cimentación son transmitidas las cargas de la estructura a un
estrato competente (rocas duras) del terreno. Dependiendo de qué tan profundo
se encuentre el suelo resistente será el tipo de cimentación que deba utilizarse.
Cuando no sea posible ejecutar una cimentación directa se debe contemplar la
posibilidad de ejecutar una cimentación profunda.
Los elementos más utilizados en trabajos de cimentaciones son los pilotes y
dentro de estos los más empleados son los pilotes de extracción previa y
hormigonados in situ.
La presente memoria dedica parte a explicar el proceso constructivo de los
principales métodos y con especial atención a los pilotes de hélice continua
(CFA), y pilotes al amparo de lodos, estudiando desde sus etapas previas hasta
el descabezado del pilote.
Posterior a esto, se elabora un análisis técnico-económico entre los pilotes CFA
y los pilotes ejecutados con lodos de excavación, para concluir con las ventajas
y desventajas que tiene uno sobre el otro.
Summary by means of the foundation the loads of the structure are transmitted to a competent stratum {rocks deep) of the area. Depending on so deep what is the resistant soil it will be the type of foundation that should be in use. When it is not possible to execute a direct foundation it is necessary to contemplate the possibility of executing a deep foundation. The elements most used in works of foundations are the piles and inside these more employees are the piles of previous extraction and concrete in situ. The present memory dedicates part to explaining the constructiva process of the principal methods and with special attention to the pilas of constant propeller {CFA), and pilas under the protection of muds, studying from his previous stages up to the beheaded one of the pile. Later to this, a technical- economic analysis is elaborated between the pilas CFA and the piles executed with muds of excavation, to conclude with the advantages and disadvantages that one has on other one.
