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

This document, in conjunction with EN ISO 11296-1, specifies 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 Standard.

Dieses Dokument legt in Verbindung mit ISO 11296-1 die Anforderungen und Prüfverfahren für Rohre und Formstücke fest, die für die Renovierung erdverlegter druckloser Entwässerungsnetze (Freispiegelleitungen) durch Lining mit einem einzelnen biegesteifen Ringraum aus einem tragenden zementhaltigen Mörtel hinter einer Kunststoffauskleidung verwendet werden. Diese Kunststoffauskleidung dient als Dauerform, die mit dem Mörtel verankert ist.
Dieses Dokument gilt für Kunststoffauskleidungen und Mörtelsysteme mit oder ohne Stahlbewehrung. Es behandelt nicht die statische Auslegung des Lining-Systems.
ANMERKUNG Es gibt Systeme mit mehreren Ringräumen, die jedoch durch Patentrechte geschützt sind und in diesem Dokument nicht behandelt werden.

Introduction

This document is a part of a System Standard for plastics piping systems of various materials used for

the renovation of existing pipelines in a specified application area. System Standards for renovation

deal with the following applications:

— ISO 11296, Plastics piping systems for renovation of underground non-pressure drainage and sewerage

networks (this application);

— ISO 11297, Plastics piping systems for renovation of underground drainage and sewerage networks

under pressure;

— ISO 11298, Plastics piping systems for renovation of underground water supply networks;

— ISO 11299, Plastics piping systems for renovation of underground gas supply networks.

These System Standards are distinguished from those for conventionally installed plastics piping

systems by the requirement to verify certain characteristics in the “as-installed condition”, after site

processing. This is in addition to specifying requirements for plastics piping system components “as

manufactured”.
Each of the System Standards comprises a:
— Part 1: General

and all applicable renovation technique family-related parts, which for non-pressure drainage and

sewerage networks include or potentially include the following:
— Part 2: Lining with continuous pipes;
— Part 3: Lining with close-fit pipes;
— Part 4: Lining with cured-in-place pipes;
— Part 5: Lining with discrete pipes;
— Part 7: Lining with spirally-wound pipes;
— Part 8: Lining with pipe segments;
— Part 9: Lining with rigidly anchored plastics inner layer (this document);
— Part 10: Lining with sprayed polymeric materials.

The requirements for any given renovation technique family are specified in part 1, applied in

conjunction with the relevant other part. For example, both ISO 11296-1 and this document

together specify the requirements relating to lining with a rigidly anchored plastics inner layer. For

complementary information, see ISO 11296-1. Not all technique families are pertinent to every area of

application and this is reflected in the part numbers included in each System Standard.

A consistent structure of clause headings has been adopted for all parts of ISO 11296, in order to

facilitate direct comparisons across renovation technique families.

Figure 1 shows the common part and clause structure and the relationship between ISO 11296-1 and

the System Standards for other application areas.

Plastics piping systems for renovation of underground

Part 9:
Lining with a rigidly anchored plastics inner layer
1 Scope

This document, in conjunction with ISO 11296-1, specifies 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.
