Trenchless construction and testing of drains and sewers
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.
Grabenlose Verlegung und Prüfung von Abwasserleitungen und -kanälen
Dieses Dokument ist anwendbar auf grabenlose Verlegungs- und Erneuerungsverfahren sowie die Prüfung neuer Abwasserleitungen und kanäle im Boden mit vorgefertigten Rohren und deren Verbindungen, die üblicherweise als Freispiegel- oder Druckrohrleitungen betrieben werden.
Renovierungsverfahren für vorhandene Druckrohrleitungen und drucklose Leitungen sind nicht Gegenstand dieses Dokuments.
Die Methoden zur grabenlosen Verlegung umfassen:
bemannte und unbemannte Verfahren;
steuerbare und nichtsteuerbare Verfahren.
ANMERKUNG 1 Bergmännische Bauverfahren und Tunnelbauverfahren für dauerhafte Bauwerke (z. B. In-Situ-Bauverfahren oder die Verwendung vorgefertigter Segmente) sind nicht Gegenstand dieses Dokuments, obwohl einzelne Festlegungen auf diese Verfahren anwendbar sein können.
ANMERKUNG 2 Das Pflugverfahren ist eine übliche Methode zum grabenlosen Einbau kleiner Rohre und Kabel. Das Verfahren fällt nicht vollständig in den Anwendungsbereich dieses Dokuments. Daher wird es im informativen Anhang D beschrieben.
Anforderungen für weitere Leitungseinbauten außer grabenlose Verlegung, z. B. im Zusammenhang mit Schächten und Inspektionsöffnungen, sind nicht im Anwendungsbereich dieses Dokuments, sondern sind in EN 1610 festgelegt. Dies gilt auch für Rohre, die im Anschluss an den grabenlosen Einbau in Start und Zielschächten bzw. Ein und Ausstiegen eingebaut werden.
Mise en oeuvre sans tranchée et essais des branchements et collecteurs d'assainissement
Le présent document s’applique aux techniques de construction et de remplacement sans tranchée, ainsi qu’aux essais de collecteurs et branchements neufs, enterrés et fonctionnant habituellement comme des canalisations à écoulement libre ou sous pression, formées de tuyaux préfabriqués et de leurs assemblages.
Les techniques de rénovation des systèmes sous pression et sans pression existants ne sont pas couvertes par le présent document.
Les méthodes de mise en œuvre sans tranchée comprennent :
- les techniques avec ou sans intervention humaine ;
- les techniques avec ou sans guidage.
NOTE 1 Les forages miniers ou les techniques d’exécution des tunnels pour les ouvrages permanents (par exemple, la construction in situ ou l’utilisation de voussoirs préfabriqués) ne sont pas couverts par le présent document, bien que certaines parties puissent s’appliquer à ces méthodes.
NOTE 2 L’insertion sans tranchée à l’aide d’un système de trancheuse est une méthode couramment utilisée pour installer les petits tuyaux et les câbles. La méthode ne rentre pas exactement dans le domaine d’application du présent document. Par conséquent, elle est décrite à l’Annexe D, informative.
Les exigences relatives à la mise en œuvre des ouvrages annexes autres que la construction sans tranchée, par exemple pour les regards de visite et boîtes d’inspection ou de branchement, ne sont pas couvertes par le présent document et sont spécifiées dans l’EN 1610. Ceci s’applique également aux tuyaux qui sont installés ultérieurement dans les puits d’entrée et de sortie.
Izvedba in preskušanje kanalov in drenaž brez izkopa
Ta dokument se uporablja za izgradnjo brez izkopa, tehnike zamenjave brez izkopa ter preskušanje novih kanalov in novih kanalizacijskih drenaž v tleh, ki običajno delujejo kot gravitacijski ali tlačni cevovodi, izdelani iz montažnih cevi in njihovih spojev.
Tehnike obnove obstoječih tlačnih in netlačnih sistemov niso zajete v tem dokumentu.
Metode izgradnje brez izkopa so:
– tehnike z osebjem ali brez njega;
– vodljive in nevodljive tehnike.
Ta dokument ne zajema rudarjenja ali tuneliranja (npr. gradnja na mestu samem ali uporaba montažnih segmentov), čeprav se lahko nekateri deli navezujejo na te metode.
Zahteve za pripadajoča montažna dela cevovoda, razen izgradnje brez izkopa, npr. za jaške in revizijske komore, niso zajete v tem dokumentu in so določene v standardu EN 1610. To velja tudi za cevi, ki se naknadno vgradijo v vstopne in izstopne jaške/jame.
