Le processus est divis\u00e9 en huit \u00e9tapes d'une cha\u00eene<\/strong>chacun avec des r\u00e9sultats concrets et des validations :<\/p>
Phase<\/th>Ce qui est fait<\/th>Questions cl\u00e9s<\/th><\/tr><\/thead>
Diagnostic et planification<\/strong><\/td>Inventaire du r\u00e9seau existant, topographie LIDAR, mesures de d\u00e9bit et projections d\u00e9mographiques.<\/td>D\u00e9finit les flux de conception et la port\u00e9e du projet.<\/td><\/tr>
2. la mod\u00e9lisation hydrologique et hydraulique<\/strong><\/td>Simulation de temp\u00eates (T = 2-50 ans) avec EPA-SWMM ou un autre logiciel.<\/td>Optimise les diam\u00e8tres et estime les d\u00e9bits de secours (CSO).<\/td><\/tr>
3. l'implantation et le dimensionnement pr\u00e9liminaire<\/strong><\/td>Fixation des hauteurs de d\u00e9part et d'\u00e9vacuation, des pentes minimales, des regards et des points critiques.<\/td>V\u00e9rifier les vitesses d'auto-nettoyage.<\/td><\/tr>
4. S\u00e9lection des mat\u00e9riaux et des structures<\/strong><\/td>Choix des tuyaux (b\u00e9ton, PVC, PRV, PEHD) et des stations de pompage, d\u00e9versoirs et bassins d'orage.<\/td>Conforme \u00e0 la norme UNE-EN 752 et aux r\u00e8glements locaux.<\/td><\/tr>
5. Ing\u00e9nierie d\u00e9taill\u00e9e<\/strong><\/td>Plans, rapports, sp\u00e9cifications, gestion des servitudes, EIE et permis.<\/td>D\u00e9finit si certains croisements doivent \u00eatre ex\u00e9cut\u00e9s avec des microtunnels.<\/td><\/tr>
6. La construction<\/strong><\/td>Excavation \u00e0 ciel ouvert ou m\u00e9thodes sans tranch\u00e9e (battage, microtunnelage) dans les zones critiques.<\/td>R\u00e9duit les coupures de trafic et les d\u00e9placements de services.<\/td><\/tr>
7. Essais et mise en service<\/strong><\/td>Tests d'\u00e9tanch\u00e9it\u00e9, vid\u00e9osurveillance, nettoyage, d\u00e9sinfection et \u00e9talonnage des compteurs.<\/td>Assure l'op\u00e9rabilit\u00e9 avant le remplissage final.<\/td><\/tr>
8. Fonctionnement et entretien<\/strong><\/td>Plan O&M avec inspections, nettoyage pr\u00e9ventif et surveillance du d\u00e9bit en temps r\u00e9el (RTC).<\/td>Minimise les d\u00e9bordements et prolonge la dur\u00e9e de vie.<\/td><\/tr><\/tbody><\/table>

Pourquoi int\u00e9grer le microtunneling ?<\/strong><\/h2>

En tranches sous les rivi\u00e8res<\/a><\/strong>routes ou centres urbains<\/a><\/strong>Le microtunnelage permet d'\u00e9viter les tranch\u00e9es profondes, de r\u00e9duire les d\u00e9viations de trafic et de maintenir la pr\u00e9cision des pentes, tout en prot\u00e9geant la conduite contre les charges dynamiques et la corrosion externe. La conception doit donc pr\u00e9voir des rayons de courbure, des puits d'attaque et d'arriv\u00e9e adapt\u00e9s au diam\u00e8tre du tunnelier.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
