(Main)Plastics piping systems - Validated design parameters of buried thermoplastics piping systems
Plastics piping systems - Validated design parameters of buried thermoplastics piping systems
This Technical Specification covers validated design parameters of buried thermoplastics piping systems for functional and structural design for the following applications:
pressure (excluding piping systems for gaseous fluids and industrial applications);
non-pressure.
The functional design is based on relevant standards and commonly used practices.
Depending on the project parameters, this route for structural design can be
either established by long term experience (within certain limitations),
or calculated according to CEN/TR 1295-2 by using thermoplastic pipe material related properties and design criteria.
NOTE The route is shown in the flowchart given in Figure 1 in 4.1.
Since in practice precise details of types of soil and installation conditions are not always available at the design stage, the choice of design assumptions is left to the judgement of the designer/specifier. In this connection, this guide can only provide general indications and advice.
Kunststoff-Rohrleitungssysteme - Bestätigte Berechnungsparameter von erdverlegten thermoplastischen Rohrleitungssystemen
Dieses Technische Spezifikation behandelt gültige Berechnungsparameter von erdverlegten thermoplastischen Rohr¬leitungssystemen für die funktionale und statische Berechnung für folgende Anwendungen:
unter Druck (mit Ausnahme von Rohrleitungssystemen für gasförmige Fluide und industrielle Anwendungen);
ohne Druck.
Die funktionale Berechnung beruht auf maßgebenden Normen und allgemein gebräuchlichen Verfahren.
In Abhängigkeit von den Projektparametern kann der Ablauf der statischen Berechnung:
entweder anhand von Langzeit-Erfahrung (innerhalb bestimmter Grenzen) festgelegt werden;
oder nach CEN/TR 1295 2 unter Verwendung von Eigenschaften und Berechnungskriterien von thermoplastischen Rohrwerkstoffen berechnet werden.
ANMERKUNG Der Ablauf ist im Flussdiagramm in 4.1, Bild 1, dargestellt.
Da in der Praxis während der Berechnungsphase nicht immer genaue Einzelheiten der Bodenarten und Verlegebedingungen verfügbar sind, unterliegt die Auswahl der Annahmen für Berechnungszwecke dem Urteilsvermögen des Konstrukteurs/Planers. In diesem Zusammenhang kann dieser Leitfaden lediglich allgemeine Hinweise und Empfehlungen bieten.

Cevni sistemi iz polimernih materialov - Veljavni parametri za načrtovanje plastomernih cevnih sistemov, položenih v zemljo
Ta tehnična specifikacija zajema potrjene parametre zasnove za plastomerne cevne sisteme, vkopane v zemljo, za funkcionalno in strukturno načrtovanje naslednjih sistemov:
– tlačnih sistemov (razen cevnih sistemov za plinaste tekočine in industrijskih cevnih sistemov);
– sistemov, ki delujejo po težnostnem principu.
Funkcionalno načrtovanje temelji na ustreznih standardih in običajno uporabljenih praksah.
Odvisno od parametrov projekta je lahko postopek strukturnega načrtovanja
– določen na podlagi dolgotrajnih izkušenj (v okviru določenih omejitev); ali
– izračunan skladno s standardom CEN/TR 1295-2, pri čemer se uporabijo lastnosti in merila za načrtovanje, povezana s plastomernim materialom za cevi.
OPOMBA: Postopek je prikazan na diagramu, podanem na slikah 1 in 4.1.
Ker v praksi podrobnosti o vrsti tal in pogojih namestitve niso vedno na voljo v fazi načrtovanja, je izbira predpostavk pri načrtovanju prepuščena presoji načrtovalca/določevalca. Zato lahko ta priročnik podaja samo splošne smernice in nasvete.

Introduction
In Europe, several design methods exist and some are still under development. The plastics pipes
industry has carried out a lot of research with full-scale trials. From these researches, graphs have been
made that show the deflection in the pipes immediately after installation. In addition, the so-called
settlement period is measured. This settlement will always take place. In case that heavy traffic is
present, the final deflection will be reached faster.
It is strongly advised to check any calculated deflection with the values in the two design graphs.
The information compiled is meant to be used by designers. The values given are meant for general
guidance.
For the purpose of design using simple methods, two compactible soil groups are used, granular and
cohesive.
If applicable, reference is made to EN 1295-1, EN 1610, CEN/TR 1046 and national practices.
