La r\u00e9habilitation de canalisations sans tranch\u00e9e constitue g\u00e9n\u00e9ralement le meilleur choix pour les chantiers en profondeur, situ\u00e9s sous des rev\u00eatements routiers ou n\u00e9cessitant un minimum de perturbations.

1. Quels sont les principaux avantages de la r\u00e9habilitation sans tranch\u00e9e ?<\/h2>\n\n\n\n
\u00c0 retenir :<\/strong> La technique sans tranch\u00e9e s'av\u00e8re particuli\u00e8rement int\u00e9ressante lorsque les co\u00fbts de remise en \u00e9tat ou d'immobilisation d\u00e9passent les \u00e9conomies r\u00e9alis\u00e9es gr\u00e2ce \u00e0 l'absence de travaux d'excavation.<\/p>\n\n\n\n
1.1 Perturbation minimale de la surface<\/strong><\/p>\n\n\n\n
La plupart des chantiers sans tranch\u00e9e ne n\u00e9cessitent que deux petites fosses d'acc\u00e8s (g\u00e9n\u00e9ralement de 2 x 3 m\u00e8tres). Pour une canalisation d'\u00e9gout r\u00e9sidentielle de 150 m\u00e8tres, une m\u00e9thode \u00e0 tranch\u00e9e ouverte perturberait environ 450 m\u00e8tres carr\u00e9s de surface. Les m\u00e9thodes sans tranch\u00e9e ne perturbent quant \u00e0 elles que moins de 6 m\u00e8tres carr\u00e9s.<\/p>\n\n\n\n
1.2 R\u00e9alisation plus rapide des projets<\/strong><\/p>\n\n\n\n
La pose d'un tron\u00e7on de canalisation de 100 m\u00e8tres \u00e0 l'aide de la technique CIPP prend g\u00e9n\u00e9ralement entre 2 et 4 jours, contre 11 \u00e0 20 jours pour la m\u00e9thode \u00e0 ciel ouvert. Cette r\u00e9duction de la main-d'\u0153uvre s'explique par la suppression de la plupart des travaux d'excavation, de remblayage et de remise en \u00e9tat de la surface.<\/p>\n\n\n\n
1.3 Dur\u00e9e de vie prolong\u00e9e<\/strong><\/p>\n\n\n\n
Les gaines CIPP modernes sont g\u00e9n\u00e9ralement con\u00e7ues pour une dur\u00e9e de vie de 50 ans. Leur surface int\u00e9rieure lisse et sans joint am\u00e9liore g\u00e9n\u00e9ralement la capacit\u00e9 d'\u00e9coulement de 30 \u00e0 40% par rapport aux anciennes canalisations pr\u00e9sentant des d\u00e9p\u00f4ts de tartre ou des irr\u00e9gularit\u00e9s au niveau des joints.<\/p>\n\n\n\n
2. Quels sont les principaux inconv\u00e9nients et limites ?<\/h2>\n\n\n\n
\u00c0 retenir :<\/strong> La technique CIPP est particuli\u00e8rement adapt\u00e9e aux canalisations endommag\u00e9es mais encore praticables. Le chemisage est la solution la plus \u00e9conomique lorsque la perte de diam\u00e8tre est acceptable. Le \u00e9clatement de canalisation convient au remplacement complet, \u00e0 l'\u00e9cart des structures fragiles.<\/p>\n\n\n\n
2.1 Co\u00fbts initiaux plus \u00e9lev\u00e9s li\u00e9s \u00e0 l'\u00e9quipement et \u00e0 l'expertise<\/strong><\/p>\n\n\n\n
\n
Mobilisation du mat\u00e9riel : 3 000\u20133 000\u20138 000 par jour pour les syst\u00e8mes CIPP de taille moyenne<\/li>\n\n\n\n
R\u00e9sine et mat\u00e9riaux de rev\u00eatement : 25\u201325\u201360 par pied lin\u00e9aire<\/li>\n\n\n\n
Tarifs des techniciens qualifi\u00e9s : 95\u201395\u2013150 par heure (contre 50\u201350\u201375 pour la main-d\u2019\u0153uvre g\u00e9n\u00e9rale dans le domaine des travaux d\u2019excavation)<\/li>\n<\/ul>\n\n\n\n
Les entrepreneurs qui r\u00e9alisent moins de 15 chantiers sans tranch\u00e9e par an parviennent rarement \u00e0 amortir leur investissement en mat\u00e9riel.<\/p>\n\n\n\n
2.2 Contraintes li\u00e9es aux mat\u00e9riaux et au chantier<\/strong><\/p>\n\n\n\n
La m\u00e9thode CIPP n'est pas adapt\u00e9e aux situations suivantes :<\/strong> Conduites dont l'affaissement actif d\u00e9passe 25% de diam\u00e8tre, ou situations dans lesquelles l'infiltration d'eau souterraine ne peut \u00eatre temporairement ma\u00eetris\u00e9e.<\/p>\n\n\n\n
Rev\u00eatement par glissement<\/strong> r\u00e9duit le diam\u00e8tre int\u00e9rieur de 15 \u00e0 30%, ce qui peut entra\u00eener des probl\u00e8mes de capacit\u00e9 pour les \u00e9gouts sanitaires.<\/p>\n\n\n\n
\u00c9clatement de canalisations<\/strong> Il pr\u00e9sente un risque de soul\u00e8vement du sol (g\u00e9n\u00e9ralement de 5 \u00e0 15 cm) et n\u2019est g\u00e9n\u00e9ralement pas recommand\u00e9 sous des ouvrages dont la couverture est inf\u00e9rieure \u00e0 1 m\u00e8tre ou \u00e0 proximit\u00e9 d\u2019infrastructures sensibles.<\/p>\n\n\n\n
3. Quand la technique sans tranch\u00e9e n'est PAS la bonne solution<\/h2>\n\n\n\n
Limites de s\u00e9lection :<\/strong> La technique sans tranch\u00e9e est particuli\u00e8rement adapt\u00e9e lorsque la canalisation est accessible et que son \u00e9tat structurel est pr\u00e9visible. La m\u00e9thode \u00e0 ciel ouvert est souvent pr\u00e9f\u00e9rable lorsque la canalisation est trop courte, trop peu profonde ou trop endommag\u00e9e.<\/p>\n\n\n\n
Dans ces situations, le creusement \u00e0 ciel ouvert constitue g\u00e9n\u00e9ralement la meilleure option :<\/p>\n\n\n\n
Condition<\/th>
Pourquoi la technique sans tranch\u00e9e pose probl\u00e8me<\/th><\/tr><\/thead>
La canalisation s'est compl\u00e8tement affaiss\u00e9e, entra\u00eenant un d\u00e9placement de terre dans le vide<\/td>
La cavit\u00e9 environnante d\u00e9passe 1,5 fois le diam\u00e8tre d'origine ; la gaine ne peut pas assurer l'\u00e9tanch\u00e9it\u00e9 par rapport au sol<\/td><\/tr>
Profondeur extr\u00eamement faible (moins d'un m\u00e8tre)<\/td>
Le soul\u00e8vement du sol risque d'endommager la chauss\u00e9e ; les travaux d'excavation sont de toute fa\u00e7on minimes<\/td><\/tr>
Alignement inconnu ou d\u00e9fauts non v\u00e9rifi\u00e9s<\/td>
La vid\u00e9osurveillance pr\u00e9alable \u00e0 l'inspection ne permet pas de cartographier l'ensemble de la ligne de mani\u00e8re fiable<\/td><\/tr>
Tr\u00e8s court tron\u00e7on de canalisation (moins de 15 m\u00e8tres)<\/td>
Les co\u00fbts de mobilisation d\u00e9passent les avantages li\u00e9s \u00e0 l'absence de tranch\u00e9es<\/td><\/tr>
Une perte de diam\u00e8tre importante est inacceptable<\/td>
Le chemisage r\u00e9duit le d\u00e9bit ; la technique CIPP peut \u00e9galement entra\u00eener une r\u00e9duction de 5 \u00e0 10%<\/td><\/tr>
Le pompage de d\u00e9rivation active n'est pas envisageable<\/td>
Les \u00e9gouts sanitaires en service ne peuvent \u00eatre vid\u00e9s ni d\u00e9tourn\u00e9s<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
\u00c0 retenir :<\/strong> La m\u00e9thode \u00e0 ciel ouvert reste la solution par d\u00e9faut pour les chantiers peu profonds, \u00e0 ciel ouvert, de faible longueur, ou lorsque la priorit\u00e9 absolue est de disposer du budget initial le plus bas possible.<\/p>\n\n\n\n

Questions-r\u00e9ponses : Foire aux questions<\/h2>\n\n\n\n
Q : La r\u00e9habilitation de canalisations sans tranch\u00e9e en vaut-elle la peine ?<\/strong> R : En r\u00e8gle g\u00e9n\u00e9rale, oui, pour les canalisations situ\u00e9es \u00e0 plus de 2,5 m\u00e8tres de profondeur, sous des surfaces pav\u00e9es ou sous des b\u00e2timents. Pour les canalisations peu profondes situ\u00e9es en pleine air, la m\u00e9thode \u00e0 ciel ouvert peut s'av\u00e9rer plus \u00e9conomique.<\/p>\n\n\n\n
Q : Quels sont les inconv\u00e9nients de la technique CIPP ?<\/strong> R : Co\u00fbts d'\u00e9quipement initiaux plus \u00e9lev\u00e9s ; n\u00e9cessite des canalisations s\u00e8ches ou d\u00e9riv\u00e9es pendant l'installation ; ne convient pas aux effondrements actifs dont le diam\u00e8tre d\u00e9passe 25% ; la qualit\u00e9 du durcissement d\u00e9pend du contr\u00f4le de la temp\u00e9rature.<\/p>\n\n\n\n
Q : Quelle est la m\u00e9thode sans tranch\u00e9e la moins ch\u00e8re ?<\/strong> R : Le chemisage par glissement pr\u00e9sente g\u00e9n\u00e9ralement les co\u00fbts de mat\u00e9riaux et d'\u00e9quipement les plus bas (60\u201360\u2013150 par pied lin\u00e9aire), mais uniquement lorsque la r\u00e9duction de diam\u00e8tre est acceptable.<\/p>\n\n\n\n
Q : Quelle est la dur\u00e9e de vie du CIPP ?<\/strong> R : Les fabricants pr\u00e9voient g\u00e9n\u00e9ralement une dur\u00e9e de vie de 50 ans. Des \u00e9tudes ind\u00e9pendantes men\u00e9es sur le terrain montrent que 80 \u00e0 95 % des gaines CIPP conservent leur int\u00e9grit\u00e9 structurelle apr\u00e8s 20 ans.<\/p>\n\n\n\n
Q : Est-il possible de r\u00e9parer une canalisation effondr\u00e9e sans tranch\u00e9e ?<\/strong> R : La technique d'\u00e9clatement de canalisations permet de remplacer des canalisations compl\u00e8tement effondr\u00e9es. Ce n'est pas le cas de la technique CIPP, qui n\u00e9cessite une canalisation h\u00f4te en bon \u00e9tat pour permettre l'insertion de la gaine.<\/p>\n\n\n\n
Q : Quelle est la diff\u00e9rence entre la technique CIPP et l'\u00e9clatement de canalisation ?<\/strong> R : La technique CIPP consiste \u00e0 installer une gaine \u00e0 l'int\u00e9rieur de la canalisation existante. La technique de \u00ab pipe bursting \u00bb consiste \u00e0 fracturer l'ancienne canalisation puis \u00e0 mettre en place une nouvelle canalisation par traction.<\/p>\n\n\n\n
Q : Le rev\u00eatement par glissement est-il adapt\u00e9 aux \u00e9gouts sanitaires ?<\/strong> R : Uniquement si la r\u00e9duction de diam\u00e8tre n'entra\u00eene pas de probl\u00e8mes de d\u00e9bit. V\u00e9rifiez les calculs de d\u00e9bit de pointe avant d'opter pour un rev\u00eatement int\u00e9rieur.<\/p>\n\n\n\n
Q : Peut-on recourir \u00e0 des m\u00e9thodes sans tranch\u00e9e sous les b\u00e2timents ?<\/strong> R : Oui. Les techniques CIPP et d'\u00e9clatement de canalisations peuvent \u00eatre mises en \u0153uvre \u00e0 partir de regards d'acc\u00e8s ext\u00e9rieurs, sans qu'il soit n\u00e9cessaire de d\u00e9molir la dalle int\u00e9rieure ni de reloger les locataires.<\/p>\n\n\n\n
