A microtunnelier t\u00e9l\u00e9command\u00e9<\/strong> peuvent atteindre une grande pr\u00e9cision en plan, en \u00e9l\u00e9vation et en pente, mais la tol\u00e9rance finale ne doit pas \u00eatre d\u00e9finie de mani\u00e8re g\u00e9n\u00e9rique : elle d\u00e9pend du diam\u00e8tre, de la longueur de la section, de la profondeur, du rayon de courbure, de la g\u00e9ologie, de la nappe phr\u00e9atique, du syst\u00e8me de guidage, du type de tunnelier et des exigences hydrauliques ou fonctionnelles de la canalisation.<\/p>

Dans les projets de le fon\u00e7age de tuyaux<\/a> y le microtunnelage dans les applications terrestres et souterraines<\/a>, La pr\u00e9cision est contr\u00f4l\u00e9e au moyen de syst\u00e8mes de guidage, de suivi topographique, de contr\u00f4le de l'alimentation et de corrections continues \u00e0 partir du poste de contr\u00f4le. Des syst\u00e8mes laser peuvent \u00eatre utilis\u00e9s pour les lignes droites ; des syst\u00e8mes gyroscopiques, des mesures topographiques compl\u00e9mentaires et un contr\u00f4le sp\u00e9cifique de l'\u00e9l\u00e9vation et de l'orientation peuvent \u00eatre incorpor\u00e9s pour les alignements courbes ou les sections complexes.<\/p>

Facteurs influen\u00e7ant la pr\u00e9cision<\/h3>

G\u00e9om\u00e9trie de l'agencement :<\/strong> la longueur totale, la profondeur, la pente, le diam\u00e8tre, les rayons de courbure et les tol\u00e9rances admissibles pour l'arbre et les dimensions. Plus la configuration est exigeante, plus il est important de d\u00e9finir le syst\u00e8me de guidage et de contr\u00f4le au stade de la conception.<\/p>

Conditions g\u00e9otechniques :<\/strong> Un terrain variable, des sols mixtes, la pr\u00e9sence de blocs, de roches, l'abrasivit\u00e9, des cavit\u00e9s ou des changements soudains de mat\u00e9riaux peuvent affecter le comportement de la t\u00eate, la pouss\u00e9e et la capacit\u00e9 de correction pendant l'avancement.<\/p>

Pr\u00e9sence d'eau et de pression frontale :<\/strong> La nappe phr\u00e9atique, la perm\u00e9abilit\u00e9 et la pression de l'eau conditionnent la stabilit\u00e9 du front et peuvent influencer le choix d'un syst\u00e8me de drainage. EPB TBM<\/a> ou un hydro-shield pour les terrains gorg\u00e9s d'eau<\/a>.<\/p>

Syst\u00e8me de guidage utilis\u00e9 :<\/strong> Les syst\u00e8mes laser sont courants pour les trac\u00e9s rectilignes, tandis que des solutions de navigation plus avanc\u00e9es et des v\u00e9rifications topographiques suppl\u00e9mentaires peuvent \u00eatre n\u00e9cessaires pour les trac\u00e9s courbes ou plus longs.<\/p>

Contr\u00f4le op\u00e9rationnel pendant l'excavation :<\/strong> La pr\u00e9cision d\u00e9pend \u00e9galement de la surveillance de param\u00e8tres tels que la pouss\u00e9e, le couple, la pression de la chambre, le volume excav\u00e9, la lubrification, la d\u00e9flexion de l'arbre et la r\u00e9action du sol.<\/p>

Comment la pr\u00e9cision est contr\u00f4l\u00e9e sur le site<\/h3>

Pendant l'ex\u00e9cution, l'\u00e9quipe technique compare en permanence la position r\u00e9elle du microtunnelier avec l'axe projet\u00e9. Si des \u00e9carts sont d\u00e9tect\u00e9s, des corrections progressives sont appliqu\u00e9es au moyen des syst\u00e8mes d'articulation et de guidage de la t\u00eate, en \u00e9vitant les man\u0153uvres brusques qui pourraient affecter le tube, le sol ou les tol\u00e9rances finales.<\/p>

Dans les \u0153uvres sensibles, telles que Travers\u00e9es d'infrastructures<\/a>, Pour les passages sous les routes, les voies ferr\u00e9es, les cours d'eau ou les zones urbaines, le contr\u00f4le de pr\u00e9cision est compl\u00e9t\u00e9 par l'auscultation, le suivi du peuplement et la v\u00e9rification topographique des environs.<\/p>

En pratique, la pr\u00e9cision r\u00e9alisable doit \u00eatre d\u00e9finie projet par projet. Pour une \u00e9valuation fiable, Eurohinca analyse le trac\u00e9, la g\u00e9otechnique, le diam\u00e8tre, la longueur, la pente, les tol\u00e9rances requises et le syst\u00e8me de guidage le plus appropri\u00e9.<\/p>

Liste de contr\u00f4le minimale pour \u00e9valuer la pr\u00e9cision attendue :<\/strong> plan de masse, profil en long, longueur, diam\u00e8tre, pente, profondeur, rayon de courbure, tol\u00e9rances d'axe et d'\u00e9l\u00e9vation, g\u00e9otechnique, nappe phr\u00e9atique, services concern\u00e9s et type de canalisation.<\/p>
