Tunnel boring machines - Air locks - Part 1: requirements for air locks utilising compressed air as the pressurising or breathing medium along with requirements for oxygen breathing systems for decompression purposes
This document applies to the design, construction, equipping, marking and testing of air locks, as defined in 3.3, which form an integral part of a tunnel boring machine. It covers requirements for personnel locks utilizing compressed air as the pressurizing or breathing medium along with requirements for oxygen breathing systems for decompression purposes. The intended use is restricted to the temperature range 5 °C to 50 °C.
This document also applies to the design, fabrication and testing of pressure bulkheads intended for use in forming in-tunnel or in-shaft air locks.
In addition, this document extends to control functions and control information relating to intermediate chambers (defined in prEN 12110-2:2023, 3.7) (if fitted) but which are accessed via the personnel lock control panel.
prEN 12110-2 sets out additional requirements to those in Part 1, for personnel locks which are intended to have the capability to utilize non-air breathing mixtures such as nitrox, trimix and heliox. prEN 12110 2 sets out additional requirements for personnel locks intended to be used for saturation exposure techniques at pressures not exceeding 20 bar(g) associated with tunnelling work. It also sets out requirements for pressurized transfer shuttles as defined in 3.3.5.
The intended use of the machinery is agreed between the manufacturer and the user taking into account information on intended use, intended location of use, intended exposure techniques and intended decompression procedures, all provided by the user.
Air locks are normally connected to or incorporated in tunnel boring machines and consequently there are a number of interfaces between machinery covered by this standard and machinery covered by prEN 16191:2022. These interfaces are identified in both standards as appropriate.
This document is not applicable to machinery and equipment which is manufactured before the date of publication of this document by CEN.
NOTE 1 Air locks can be formed by the construction of one or more bulkheads in a tunnel secured to the tunnel lining. However, although the equipment required for tunnel air locks will be similar to that for TBM air locks, prEN 12110-1:2023 applies only to the design, fabrication and testing of bulkheads in this situation.
NOTE 2 Air locks can also be attached to an air deck in a shaft. Again, although the equipment required for such air locks will be similar to that for TBM air locks, prEN 12110-1:2023 applies only to the design, fabrication and testing of bulkheads (air decks) in shafts.
This document deals with all significant hazards, hazardous situations and events relevant to such machinery when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
The supply of compressed air and oxygen to the air lock is partly within the scope of prEN 12110-1:2023 and partly within the scope of prEN 16191:2022 and this division is clearly indicated within the text of both standards.
Vibration, noise and EMC (Electromagnetic compatibility) hazards are not significant hazards for air locks.
Tunnelbohrmaschinen - Druckluftschleusen - Teil 1: Sicherheitstechnische Anforderungen an Druckluftschleusen, die Druckluft als Druck- oder Atemmedium verwenden, sowie Anforderungen an Sauerstoff-Atemsysteme zum Zweck der Dekompression
Dieses Dokument gilt für Form, Aufbau, Ausstattung, Kennzeichnung und Prüfung von Druckluftschleusen, wie in 3.3 festgelegt, die einen integralen Teil von Tunnelbaumaschinen darstellen. Es deckt die Anforderungen an Personenschleusen ab, die Druckluft als Druck- oder Atemmedium verwenden, sowie Anforderungen an Sauerstoff-Atemsysteme zum Zweck der Dekompression ab. Die bestimmungsgemäße Verwendung ist auf den Temperaturbereich von 5 °C bis 50 °C beschränkt.
Dieses Dokument gilt auch für die Form, Herstellung und Prüfung von Druckwänden zur Bildung von Druckluftschleusen innerhalb des Tunnels oder Schachtes.
Zudem erstreckt sich das Dokument auf Steuerfunktionen und Steuerinformationen im Hinblick auf Zwischenkammern (in prEN 12110 2:2023, 3.7, definiert) (sofern vorhanden), auf die jedoch über den Bedienungsstand der Personenschleuse zugegriffen wird.
prEN 12110 2 legt für Personenschleusen, die auf die Möglichkeit zur Nutzung von Atemgasmischungen außer Luft, wie etwa Nitrox, Trimix und Heliox ausgelegt sind, zusätzliche Anforderungen fest, die sich von denen in Teil 1 unterscheiden. prEN 12110 2 legt zusätzliche Anforderungen an Personenschleusen fest, die zur Anwendung von Sättigungsverfahren bei Drücken bis maximal 20 bar(g) im Zusammenhang mit Tunnelbauarbeiten, ausgelegt sind. Es legt zudem Anforderungen an unter Druck stehenden Transfer Shuttles, wie in 3.3.5 definiert, fest.
Die bestimmungsgemäße Verwendung der Maschine wird, unter Beachtung von Informationen zur bestimmungsgemäßen Verwendung, des vorgesehenen Einsatzortes, der vorgesehenen Verfahren und Dekompressionsverfahren, die alle vom Anwender zur Verfügung gestellt werden, zwischen dem Hersteller und dem Anwender vereinbart.
Druckluftschleusen sind für gewöhnlich mit Tunnelbohrmaschinen verbunden oder in diese integriert, sodass folglich mehrere Schnittstellen zwischen den durch diese Norm abgedeckten Maschinen und durch prEN 16191:2023 abgedeckte Maschinen vorliegen. Diese Schnittstellen sind in beiden Normen als angemessen anerkannt.
Diese Europäische Norm gilt nicht für Maschinen und Ausrüstung, die hergestellt wurden, bevor CEN dieses Dokument veröffentlichte.
ANMERKUNG 1 Druckluftschleusen können durch die Konstruktion einer oder mehrerer, an der Tunnelauskleidung gesicherten Trennwände in einem Tunnel errichtet werden. Obwohl die für Tunnel-Druckluftschleusen erforderliche Ausrüstung denen für TBM Druckluftschleusen ähnelt, gilt prEN 12110 1:2023 jedoch ausschließlich für die Form, Herstellung und Prüfung von Trennwänden in dieser Situation.
ANMERKUNG 2 Druckluftschleusen können auch an ein Luftdeck in einem Schacht angeschlossen sein. Auch hier gilt, obwohl die für derartige Druckluftschleusen erforderliche Ausrüstung denen für TBM Druckluftschleusen ähnelt, gilt prEN 12110 1:2023 jedoch ausschließlich für die Form, Herstellung und Prüfung von Trennwänden (Luftdecks) in Schächten.
Dieses Dokument behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die auf Druckluftschleusen und Druckwände zutreffen, wenn sie bestimmungsgemäß und entsprechend den vorhersehbaren Bedingungen des Herstellers verwendet werden (siehe Anhang A).
Die Druckluft- und Sauerstoffversorgung zur Druckluftschleuse fällt teilweise in den Anwendungsbereich von prEN 12110 1:2023 und teilweise in den Anwendungsbereich von prEN 16191:2023 und auf diese Einteilung wird innerhalb des jeweiligen Textes in beiden Normen deutlich hingewiesen.
Gefährdungen durch Schwingungen, Lärm und EMV (Elektromagnetische Verträglichkeit) sind keine signifikanten Gefährdungen für Druckluftschleusen.
Tunneliers - Sas de transfert - Partie 1 : Prescriptions relatives aux sas de transfert utilisant de l'air comprimé comme fluide de pressurisation ou de respiration et prescriptions relatives aux systèmes respiratoires à oxygène pour la décompression
Le présent document porte sur la conception, la fabrication, la fourniture, le marquage et les essais des sas de transfert définis en 3.3, qui font partie intégrante d'un tunnelier. Il couvre les prescriptions relatives aux sas à personnel utilisant de l'air comprimé comme fluide de pressurisation ou de respiration ainsi que les prescriptions relatives aux systèmes respiratoires à oxygène pour la décompression. L'utilisation normale se limite à la plage de températures comprises entre 5 °C et 50 °C.
Le présent document s'applique également à la conception, à la fabrication et aux essais des cloisons étanches destinées à être utilisées pour former des sas de transfert dans le tunnel ou dans le puits.
Le présent document s'étend en outre aux fonctions de commande et aux informations de commande relatives aux chambres intermédiaires (définies dans le prEN 12110-2:2023, 3.7) (le cas échéant), mais qui sont accessibles par le panneau de commande du sas à personnel.
Le prEN 12110-2 donne des prescriptions qui complètent celles de la Partie 1, pour les sas à personnel destinés à permettre l'utilisation de mélanges respiratoires non-air tels que le nitrox, le trimix et l'héliox. Le prEN 12110 2 définit des prescriptions supplémentaires pour les sas à personnel destinés à être utilisés pour des techniques d'exposition par saturation à des pressions ne dépassant pas 20 bars(g) associées aux travaux de creusement de tunnels. Il établit également des prescriptions concernant les navettes de transfert pressurisées telles que définies en 3.3.5.
L'utilisation normale de la machine est convenue entre le fabricant et l'utilisateur, en prenant en compte les informations relatives à l'utilisation normale, le lieu d'utilisation prévu, les techniques d'exposition prévues et les procédures de décompression prévues, l'ensemble étant fourni par l'utilisateur.
Les sas de transfert sont normalement connectés ou intégrés aux tunneliers, il existe par conséquent un certain nombre d'interfaces entre les machines couvertes par la présente norme et les machines couvertes par le prEN 16191:2023. Ces interfaces sont identifiées dans les deux normes, le cas échéant.
Le présent document ne s'applique pas aux machines et aux équipements fabriqués avant la date de publication du présent document par le CEN.
NOTE 1 Les sas de transfert peuvent être formés par la construction d'une ou plusieurs cloisons étanches dans un tunnel, fixées au revêtement du tunnel. Toutefois, bien que l'équipement requis pour les sas de transfert des tunnels soit similaire à celui des sas de transfert des tunneliers, le projet de norme prEN 12110-1:2023 s'applique uniquement à la conception, à la fabrication et aux essais des cloisons étanches dans cette situation.
NOTE 2 Les sas de transfert peuvent aussi être fixés à un aérage dans un puits. Une fois encore, bien que l'équipement requis pour ces sas de transfert soit similaire à celui des sas de transfert des tunneliers (TBM), le projet de norme prEN 12110-1:2023 s'applique uniquement à la conception, à la fabrication et aux essais des cloisons étanches (aérages) dans les puits.
Le présent document traite de tous les phénomènes, situations et événements dangereux significatifs relatifs aux engins de terrassement lorsqu'ils sont utilisés comme prévu ou dans des conditions de mauvais usage que le fabricant peut raisonnablement prévoir (voir l'Annexe A).
L'alimentation du sas de transfert en air comprimé et en oxygène relève en partie du domaine d'application du prEN 12110-1:2023 et en partie du domaine d'application du prEN 16191:2023. Cette division est clairement indiquée dans le texte des deux normes.
Les phénomènes dangereux engendrés par les vibrations, le bruit et la CEM (compatibilité électromagnétique) ne constituent pas des phénomènes dangereux significatifs pour les sas de transfert.

Introduction
This document is a type C standard as stated in EN ISO 12100:2010.
The machinery and equipment concerned and the extent to which hazards, hazardous situations and
events are covered are indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards, for machines that have been designed and built according to the provisions of this type C
standard.
1 Scope
This document applies to the design, construction, equipping, marking and testing of air locks, as defined
in 3.3, which form an integral part of a tunnel boring machine. It covers requirements for personnel locks
utilizing compressed air as the pressurizing or breathing medium along with requirements for oxygen
breathing systems for decompression purposes. The intended use is restricted to the temperature range
5 °C to 50 °C.
This document also applies to the design, fabrication and testing of pressure bulkheads intended for use
in forming in-tunnel or in-shaft air locks.
In addition, this document extends to control functions and control information relating to intermediate
chambers (defined in prEN 12110-2:2023, 3.7) (if fitted) but which are accessed via the personnel lock
control panel.
prEN 12110-2 sets out additional requirements to those in Part 1, for personnel locks which are intended
to have the capability to utilize non-air breathing mixtures such as nitrox, trimix and heliox.
prEN 12110-2 sets out additional requirements for personnel locks intended to be used for saturation
exposure techniques at pressures not exceeding 20 bar(g) associated with tunnelling work. It also sets
out requirements for pressurized transfer shuttles as defined in 3.3.5.
The intended use of the machinery is agreed between the manufacturer and the user taking into account
information on intended use, intended location of use, intended exposure techniques and intended
decompression procedures, all provided by the user.
Air locks are normally connected to or incorporated in tunnel boring machines and consequently there
are a number of interfaces between machinery covered by this standard and machinery covered by
prEN 16191:2023. These interfaces are identified in both standards as appropriate.
This document is not applicable to machinery and equipment which is manufactured before the date of
publication of this document by CEN.
NOTE 1 Air locks can be formed by the construction of one or more bulkheads in a tunnel secured to the tunnel
lining. However, although the equipment required for tunnel air locks will be similar to that for TBM air locks,
NOTE 2 Air locks can also be attached to an air deck in a shaft. Again, although the equipment required for such
air locks will be similar to that for TBM air locks, prEN 12110-1:2023 applies only to the design, fabrication and
testing of bulkheads (air decks) in shafts.
This document deals with all significant hazards, hazardous situations and events relevant to such
machinery when they are used as intended and under conditions of misuse which are reasonably
foreseeable by the manufacturer (see Annex A).
The supply of compressed air and oxygen to the air lock is partly within the scope of prEN 12110-1:2023
and partly within the scope of prEN 16191:2023 and this division is clearly indicated within the text of
both standards.
Vibration, noise and EMC (Electromagnetic compatibility) hazards are not significant hazards for air
locks.
