Aidico inspecciona dovelas de hormigón armado en parque eólicoAidico Inspects dovelas of armed concrete in wind park
2 October 2012
Acciona Power has hired to
Aidico, Technological Institute of the Construction, for the design of a plan of measures for the inspection and evaluation in-situ of the anomalies detected in the dovelas of armed concrete of the wind park of Els Escambrons, Almatret in Lleida. The big aerogeneradores of the tubular towers that usually are of steel or of celosía, also manufacture in concrete. These new structures manufactured with this material compete with the towers of steel, more widespread and begin to proliferate by all the national territory.
The hormigonado of these towers represents all a challenge, as it employs concrete of high resistance and autocompactable. The conditions of manufacture have to be very strict for his correct execution according to the admissible criteria for a structural element that has to have a prolonged useful life (until some 25 years).
Inspection of dovelas of concrete.
The group of Methods of Essay No Destructive (END) of Aidico has realised a study of inspection and evaluation no destructive of dovelas of armed concrete of 20 metres of length and different radios of curvature. This exploration has consisted in the inspection by means of technical equipment like the radar of subsoil and ultrasonic tomography, with the end to verify the position of the bars of armed and presence of fissures or oquedades no expected in the interior.
The application of these technicians has served to evaluate the minimum thicknesses of the coating of the armed in said dovelas. This parameter is key for evidenciar future problems of corrosion. Likewise they have been able to detect oquedades in different points and with different sizes or dimensions. In this sense, this information will allow the improvement of the quality of the product and descartar like this possible structural failures.
This work has served for evidenciar the potentiality of the integration and conjoint interpretation of the technical employees, positioning to Aidico in a national referent in the field of the inspection in-situ of structures of complex concrete.
