DIGA DI BELLUNO COR+ DN 500 | diga di Val Schener (BL 2021) - Val Schener dam

            Sistema di evacuazione 15.000 mc di fanghi stagnanti sul fondo del lago della diga. Quota sollevamento fanghi = 70 m per immissione in vasca di disconnessione. Diluizione fanghi con acqua per rispetto dei limiti di legge sulla concentrazione. Controlli ambientali molto rigorosi, lo strumento di misurazione della torbidità (turbidimetro) si attiva ogni 15 secondi. Dalla vasca parte il tubo (fangodotto) che per gravità trasporta (parzialmente pieno) il liquido con i fanghi allo scarico in una cascata della diga. Posizionamento fuori terra della tubazione PP corrugata a doppia parete SN16 su versante scosceso, con oggettive difficoltà cantieristiche di realizzazione e di sicurezza degli operatori. Movimentazione tubi in loco tramite elicottero. Il sistema Cor+  è stato scelto principalmente per:
- maggiore leggerezza (rispetto ad altri tipi di tubazioni)
- facilità di giunzione nelle condizioni operative specifiche
- elevata capacità di tenuta meccanica anti sfilamento
- elevata affidabilità di tenuta idraulica
- elevata resistenza all'abrasione
La scelta ha consentito di svolgere il lavoro con maggiore velocità e sicurezza per gli operatori (rispetto ai tubi di acciaio previsti a progetto), oltre che per il conseguimento di sensibili economie generali

Evacuation system of 15,000 cubic meters of stagnant sludge on the bottom of the dam lake. Sludge lifting altitude = 70 m for placing in the disconnection tank. Dilution of sludge with water to comply with the concentration limits set by law. Very rigorous environmental controls, the turbidity measuring instrument (turbidimeter) activates every 15 seconds. From the tank starts the pipe (sludge pipeline) which by gravity transports (partially full) the liquid with the sludge to the discharge in a cascade of the dam. Above ground positioning of the double wall corrugated PP pipe SN16 on a steep slope, with objective construction site difficulties and operator safety. On-site pipe handling by helicopter. The Cor+ system was chosen mainly for:
- greater lightness (compared to other types of pipes)
- ease of joining under specific operating conditions
- high capacity of anti-slip mechanical seal
- high reliability of hydraulic seal
- high resistance to abrasion
The choice made it possible to carry out the work with greater speed and safety for the operators (compared to the steel pipes prescribed in the project), as well as for the achievement of significant general savings
