General requirements for components specifically designed for use in trenchless construction of drains and sewers

General requirements for components specifically designed for use in trenchless construction of drains and sewers

This European Standard specifies general requirements for pipes and their joints intended for use in drains and sewers which are installed using trenchless construction methods "pipe jacking", "microtunnelling" and "pilot jacking" as defined in EN 12889 as gravity systems, according to EN 476 where any pressure to occur is a maximum of 40 kPa or operated under pressure according to EN 773 where pressure can be more than
40 kPa.
This European Standard provides the general basis for the preparation or revision of product standards. It is not applicable for the evaluation of products and construction techniques.
It is applicable as a reference for drawing up a product specification, if there is no product standard available.
This European Standard applies to components to be used in domestic waste water, rainwater and surface water and other waste waters (e.g. industrial waste water) that will not damage the components.

Allgemeine Anforderungen an Bauteile, die bei grabenlosem Einbau von Abwasserleitungen und -kanälen verwendet werden

Diese Europäische Norm legt allgemeine Anforderungen an Vortriebsrohre und deren Verbindungen fest, die für Abwasserkanäle und -leitungen bestimmt sind, und mit den grabenlosen Verfahren "Rohrvortrieb", "Mikrotunnelbau" sowie "Pilotrohrvortrieb" nach EN 12889 eingebaut und als Schwerkraftentwässerungssysteme nach EN 476 mit einem Druck von maximal 40 kPa oder nach EN 773 auch mit einem Druck über 40 kPa betrieben werden.
Diese Europäische Norm dient als allgemeine Grundlage für die Ausarbeitung oder Überarbeitung von Produktnormen. Sie gilt nicht für die Bewertung von Produkten und Bauverfahren.
Sie dient als Quellenangabe für die Aufstellung einer Produktbeschreibung, wenn es keine Produktnorm gibt.
Diese Europäische Norm gilt für Bauteile, die dazu benutzt werden, häusliches Schmutzwasser, Regen- und Oberflächenwasser sowie andere Abwässer (z. B. industrielles Abwasser), die die Bauteile nicht beschädigen, abzuleiten.

Prescriptions générales pour composants utilisés dans la construction des réseaux d'évacuation et d'assainissement sans tranchée

La présente Norme européenne spécifie les prescriptions générales concernant les tuyaux et leurs joints destinés à être utilisés dans les réseaux d'évacuation et d'assainissement installés grâce à des techniques sans tranchée, de " fonçage ", " microtunnelage " et "pousse-tube" définies dans l'EN 12889 comme des systèmes par gravité, selon l'EN 476 dans le cas où la pression reste inférieure à 40 kPa, ou mis en �uvre sous une pression conforme à l'EN 773, lorsque la pression peut être supérieure à 40 kPa.
La présente Norme européenne fournit une base générale pour la préparation ou la révision des normes de produit. Elle ne s'applique ni à l'évaluation des produits ni aux techniques de construction.
Elle peut être utilisée comme référence pour rédiger la spécification d'un produit, si aucune norme correspondante n'existe.
La présente Norme européenne s'applique aux éléments utilisés avec les eaux usées domestiques, les eaux de pluie et de surface et les autres rejets liquides (comme par exemple les rejets liquides industriels) qui ne doivent pas endommager lesdits éléments.

Trenchless construction and testing of drains and sewers
SIST EN 12889:2023

This document is applicable to the trenchless construction, trenchless replacement techniques and testing of new drains and new sewers in the ground and usually operating as gravity or pressure pipelines, formed using prefabricated pipes and their joints.
Renovation techniques for existing pressure and non-pressure systems are not covered by this document.
Methods of trenchless construction include:
- manned and unmanned techniques;
- steerable and non-steerable techniques.
NOTE 1 Mining or tunnelling techniques for permanent structures (e.g. in situ construction or the use of prefabricated segments) are not covered by this document although some parts can apply to these methods.
NOTE 2 Trenchless insertion using a pipe plough system is a common method for installing small pipes and cables. The method does not exactly cope with the scope of this document. Therefore, it is described in the informative Annex D.
Requirements for associated pipeline installation work other than trenchless construction, e.g. for manholes and inspection chambers, are not covered by this document and are specified in EN 1610. This also applies to pipes that are subsequently installed within entry and exit shafts/pits.

Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks - Part 9: Lining with a rigidly anchored plastics inner layer (ISO 11296-9:2022)
SIST EN ISO 11296-9:2023

This document, in conjunction with ISO 11296‑1, specifies the requirements and test methods for pipes and fittings for the renovation of underground non-pressure drainage and sewerage networks by lining with a single rigid annulus of structural cementitious grout formed behind a plastics inner layer. This plastics layer serves as permanent formwork anchored to the grout.
This document is applicable to plastics inner layers and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system.
NOTE      Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.
