Afin d'\u00e9tudier la faisabilit\u00e9 d'un chantier sans tranch\u00e9e, Eurohinca a besoin de plans et profils, longueur, diam\u00e8tre, profondeur, g\u00e9otechnique, nappe phr\u00e9atique, services publics concern\u00e9s, espacement des puits, acc\u00e8s, restrictions sur le site et calendrier pr\u00e9vu<\/strong>. Ces donn\u00e9es permettent d'\u00e9valuer la m\u00e9thode de construction, les principaux risques et la pr\u00e9paration d'une offre technico-commerciale.<\/p>

Selon Eurohinca, sp\u00e9cialiste des technologies sans tranch\u00e9e depuis 1996, dans une phase pr\u00e9liminaire, il n'est pas toujours n\u00e9cessaire d'avoir le projet complet, mais il est n\u00e9cessaire d'avoir suffisamment d'informations pour analyser la constructibilit\u00e9 de la travers\u00e9e, de la canalisation, de l'\u00e9missaire, du captage ou de l'infrastructure souterraine.<\/p>

Ces donn\u00e9es permettent de d\u00e9cider si la solution peut \u00eatre mise en \u0153uvre au moyen de le fon\u00e7age de tuyaux<\/a>, forage horizontal directionnel<\/a>, Direct Pipe<\/a> ou d'autres technologies sans tranch\u00e9e.<\/p>

Informations minimales recommand\u00e9es<\/h3>

Donn\u00e9es g\u00e9om\u00e9triques de l'agencement :<\/strong> le plan, le profil longitudinal, la longueur totale, les dimensions de l'entr\u00e9e et de la sortie, la profondeur pr\u00e9vue, la pente, les rayons de courbure \u00e9ventuels et les tol\u00e9rances admissibles de l'arbre et des dimensions.<\/p>

Caract\u00e9ristiques de conduite :<\/strong> les diam\u00e8tres int\u00e9rieur et ext\u00e9rieur, le mat\u00e9riau du tuyau, l'utilisation pr\u00e9vue - assainissement, alimentation, gaz, drainage, \u00e9missaire, captage ou autre service, la pression de service le cas \u00e9ch\u00e9ant et les exigences en mati\u00e8re d'\u00e9tanch\u00e9it\u00e9.<\/p>

Informations g\u00e9otechniques et hydrog\u00e9ologiques :<\/strong> les forages, les profils g\u00e9ologiques, les tests disponibles, la pr\u00e9sence de roches, de blocs, de sols mixtes, de mat\u00e9riaux abrasifs, la nappe phr\u00e9atique, la perm\u00e9abilit\u00e9 et les \u00e9ventuelles pressions d'eau.<\/p>

Conditions environnementales :<\/strong> les infrastructures travers\u00e9es, les services existants, les b\u00e2timents proches, les routes, les voies ferr\u00e9es, les cours d'eau, les zones urbaines, les zones prot\u00e9g\u00e9es, les servitudes, les permis connus et les contraintes environnementales.<\/p>

Espace disponible pour les travaux de g\u00e9nie civil et la logistique :<\/strong> l'emplacement possible des puits d'attaque et de r\u00e9ception, les dimensions disponibles, l'acc\u00e8s des machines, les zones de stockage, les restrictions de circulation, l'alimentation \u00e9lectrique, la gestion des boues ou des mat\u00e9riaux excav\u00e9s et les conditions de levage. Ces informations permettent de dimensionner les puits d'entra\u00eenement vertical et microtunnelier<\/a> et la travaux de g\u00e9nie civil associ\u00e9s aux technologies sans tranch\u00e9e<\/a>.<\/p>

Objectif du client et champ d'application souhait\u00e9 :<\/strong> phase du projet, calendrier cible, port\u00e9e pr\u00e9vue d'Eurohinca - faisabilit\u00e9, l'assistance technique et l'ing\u00e9nierie pour les chantiers sans tranch\u00e9e<\/a>, Les documents suivants sont requis pour les appels d'offres, les demandes d'information ou les demandes de prix.<\/p>

En fonction de la g\u00e9ologie, de la pr\u00e9sence d'eau et des tol\u00e9rances du projet, ces informations aident \u00e9galement \u00e0 la conception du projet. choix du tunnelier<\/a>, pour \u00e9valuer l'utilisation des hydro-shield pour les terrains gorg\u00e9s d'eau<\/a> et choisir le syst\u00e8me d'excavation le plus appropri\u00e9.<\/p>

Liste de contr\u00f4le minimale pour la soumission d'une demande de renseignements techniques :<\/strong> plan de masse, profil longitudinal, longueur, diam\u00e8tre, profondeur, g\u00e9otechnique, nappe phr\u00e9atique, services concern\u00e9s, emplacement des puits, acc\u00e8s, restrictions de travail et d\u00e9lai de r\u00e9alisation.<\/p>

Demander un \u00e9tude de faisabilit\u00e9 pr\u00e9liminaire ou appel d'offres pour un chantier de construction sans tranch\u00e9e<\/a> en joignant les plans, le profil longitudinal et les donn\u00e9es g\u00e9otechniques disponibles.<\/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":"
