Plastics piping systems for non-pressure underground conveyance and storage of non-potable water - Boxes used for infiltration, attenuation and storage systems - Part 4: Guidance for structural design of modular systems
This document gives guidance on the structural design of underground modular systems for infiltration, attenuation and storage of surface water under various conditions of loading. The procedures are explained, with the appropriate variables in the design formulae, and provides graphical information on vehicle surcharge loadings.
These modular systems are constructed from multiple cuboid shaped thermoplastic boxes generally with ancillary components such as inlet/outlet connectors, vents, and access/inspection provision. This guidance is for the design of modular systems conforming to EN 17152-1.
The boxes, including integral components, are injection moulded, extruded or thermoformed thermoplastics, manufactured from polypropylene (PP) or unplasticized poly(vinyl chloride) (PVC-U), and are intended to be used as elements in a modular system where the manufacturer has clearly stated in the documentation how the components are assembled to create a complete infiltration, attenuation or storage system.
Outside the scope of this document are the following conditions:
- seismic loads,
- lateral loads from adjacent structures and embankments,
- influence of trees,
- backfill materials not according to CEN/TR 17179 [1].
Geotextile and/or geomembrane used with modular systems are outside the scope of this document.
NOTE If reference is made in this document to Eurocode standards, the conditions in a national foreword or national annex are normally stated.
Kunststoff-Rohrleitungssysteme für die drucklose unterirdische Entwässerung für Nicht-Trinkwasser - Versickerungsblöcke zur Verwendung in Infiltrations-, Zwischenspeicher- und Speichersystemen - Teil 4: Leitfaden für die statische Berechnung von Systemen
Dieses Dokument enthält Leitlinien für die statische Berechnung von unterirdischen modularen Systemen für die Infiltration, Zwischenspeicherung und Speicherung von Niederschlagswasser unter verschiedenen Lastfällen. Die Verfahren werden zusammen mit den entsprechenden Variablen in Bemessungsgleichungen erläutert und Informationen über Verkehrsauflasten werden grafisch dargestellt.
Derartige modulare Systeme werden aus mehreren quaderförmigen thermoplastischen Versickerungsblöcken zusammengesetzt, im Allgemeinen mit zusätzlichen Komponenten wie Ein /Auslassanschlüssen, Lüftungsöffnungen und Zugangs /Inspektionsvorrichtungen. Dieser Leitfaden bezieht sich auf die Ausführung modularer Systeme nach EN 17152 1.
Die Versickerungsblöcke einschließlich integraler Bestandteile sind aus Polypropylen (PP) oder weichmacherfreiem Polyvinylchlorid (PVC U) gefertigte spritzgegossene, extrudierte oder warmgeformte Thermoplaste und für die Verwendung als Elemente in einem modularen System vorgesehen, für das der Hersteller in der Dokumentation eindeutig angegeben hat, wie die Bauteile montiert werden, sodass ein vollständiges Infiltrations , Zwischenspeicher- oder Speichersystem entsteht.
Die folgenden Bedingungen liegen außerhalb des Anwendungsbereichs dieses Dokuments:
- seismische Lasten;
- horizontale Lasten durch angrenzende Bauwerke und Dämme;
- Einwirkungen durch Bäume;
- Verfüllmaterial, das nicht CEN/TR 17179 [1] entspricht.
Die Verwendung von Geotextilien und/oder Geomembranen in Kombination mit modularen Systemen liegt außerhalb des Anwendungsbereichs dieses Dokuments.
ANMERKUNG Wenn in diesem Dokument auf Eurocode-Normen verwiesen wird, werden die Bedingungen üblicherweise in einem nationalen Vorwort oder nationalen Anhang angegeben.

Introduction
The products covered by this document are part of surface water (previously referred to as stormwater)
management systems.
Geocellular systems are an assemblage of boxes, in one or more layers, for which the material and the
material characteristics are according to EN 17152-1. The assemblage is considered as a modular system
for the purposes of this design guidance.
The general principles of designing structures to withstand long-term loads are well established.
However, their application is generally for rigid structures such as concrete bridges, e.g. Eurocode 2
series: Design of concrete structures (EN 1992).
The behaviour of thermoplastics is more complex and the design loads which may be experienced may
be different in magnitude and action. This guidance is intended to aid the designer in determining realistic
loadings in the design of thermoplastic geocellular modular systems.
NOTE In this guidance, the terms pressure(s) and strength will be used, corresponding to actions and
resistances in Eurocodes.
1 Scope
This document gives guidance on the structural design of underground modular systems for infiltration,
attenuation and storage of surface water under various conditions of loading. The procedures are
explained, with the appropriate variables in the design formulae, and provides graphical information on
vehicle surcharge loadings.
These modular systems are constructed from multiple cuboid shaped thermoplastic boxes generally with
ancillary components such as inlet/outlet connectors, vents, and access/inspection provision. This
guidance is for the design of modular systems conforming to EN 17152-1.
The boxes, including integral components, are injection moulded, extruded or thermoformed
thermoplastics, manufactured from polypropylene (PP) or unplasticized poly(vinyl chloride) (PVC-U),
and are intended to be used as elements in a modular system where the manufacturer has clearly stated
in the documentation how the components are assembled to create a complete infiltration, attenuation
or storage system.
Outside the scope of this document are the following conditions:
— seismic loads,
— lateral loads from adjacent structures and embankments,
— influence of trees,
— backfill materials not according to CEN/TR 17179 [1].
Geotextile and/or geomembrane used with modular systems are outside the scope of this document.
NOTE If reference is made in this document to Eurocode standards, the conditions in a national foreword or
national annex are normally stated.
