HOME CVA GROUP DAM PROJECT BUILDING SITE EXHIBITION VALGRISENCHE BROCHURE PHOTO VIDEO Home Home The works for the adaptation of the Beauregard dam began on 20 October 2011 and consist of the demolition of the upper dam portion . The reason for this intervention lies in the presence of what in technical terms is called " Deep Gravitative Deformation of the Slope " insistent on the left bank of the basin. Basically it is a movement that affects the left side and that, in this case, interacts with the structure of the dam, tending to compress its arch. This deformation, by its nature, is not subject to sudden accelerations, which in any case would be promptly detected by the daily measurements. show all Works planned in 2014 To date, 30 flights have been carried out for a total of 85,000 m 3 of concrete demolished by explosives which have allowed the facing of the dam to be lowered by 30 meters. The dam previously visible for 72 meters, therefore has a height of 42 meters. For the year 2014, demolition operations are planned that will reduce the height of the dam by another 22 meters. The expected sprints are between 25 and 30, with the consequent demolition of approximately 75,000 m 3 of concrete, which, like last year, will be carried out on a weekly basis, starting from April / May. The methodology chosen for the demolition takes place through controlled abatement with explosives, applied to an intense mesh of perforations, located and directed on the basis of a specific specialist study, which ensures the containment of the volutes and the orientation of the parabolas of the fall of the material. produced by the explosion. In order to guarantee the safety of the personnel working on the construction site and the population, a siren positioned in Bonne will announce the sprints. Finally, allocation activities will be carried out within the construction site of all the debris both upstream and downstream of the dam and the access track to the new crowning along the right orographic bank of the reservoir will be built. Dates Upcoming Explosions 08 July 2014 CAUTION: A siren will announce the explosions (flown) according to the following scheme: - 3 rings 30 min. before the sprint - 2 rings 20 min. before the sprint - 1 ring 5 min. before the sprint - 1 ring about 15 min. after the sprint From 30 min. before the sprint until the end of sprint signal it will be forbidden to enter the SAFETY AREA VAT number 01013130073
