Execution of special geotechnical works - Ground anchors
1.1 This European Standard covers ground anchors grouted into the ground which are stressed and tested. They can be used for permanent or temporary applications.
NOTE For the purpose of this standard the term ‘anchor(s)’ refers to ‘ground anchor(s)’.
1.2 The anchors are designed in accordance with EN 1997-1 and are tested in accordance with prEN ISO 22477 5.
1.3 Typical bond and compression type anchors are shown in Figure 1 and Figure 2.
1.4 The term "ground" is taken to encompass soil, rock and fill already in place or existing prior to the execution of the construction work.
1.5 The planning and design of ground anchors calls for experience and knowledge in this specialised field.
1.6 The installation and testing phases require skilled, qualified labour and supervision.
1.7 This standard cannot replace the knowledge of specialist personnel and the expertise of experienced contractors required to apply this standard.
1.8 This standard does not address systems such as tension piles, screw anchors, mechanical anchors, soil nails, dead-man anchors or expander anchors as these do not fulfil the requirements of this standard.
Ausführung von Arbeiten im Spezialtiefbau - Verpressanker
1.1 Diese Europäische Norm gilt für Verpressanker, die mit dem Baugrund durch Verpressgut verbunden, vorgespannt und geprüft werden. Diese können sowohl für Dauer- als auch für Kurzzeitanwendungen eingesetzt werden.
ANMERKUNG Für die Anwendung dieser Norm bezieht sich der Begriff „Anker“ auf „Verpressanker“.
1.2 Die Verpressanker werden nach EN 1997 1 bemessen und nach prEN ISO 22477 5 geprüft.
1.3 Typische Verbund- und Druckrohranker sind in Bild 1 und Bild 2 dargestellt.
1.4 Die Bezeichnung „Baugrund“ umfasst Boden, Fels und Auffüllungen, die entweder bereits vorhanden waren oder vor der Ausführung der Bauarbeiten eingebracht wurden.
1.5 Planung und Bemessung von Verpressankern erfordern Erfahrung und Kenntnisse auf diesem Spezial-gebiet.
1.6 Einbau und Prüfung erfordern erfahrene und qualifizierte Facharbeiter und eine qualifizierte Aufsicht.
1.7 Diese Norm kann die Kenntnisse von Fachleuten und den Sachverstand von erfahrenen Bauunternehmen, die für die Anwendung dieser Norm erforderlich sind, nicht ersetzen.
1.8 Diese Norm befasst sich nicht mit Verfahren wie Zugpfählen, Schraubankern, mechanischen Verankerungen, Bodennägeln, Toter-Mann-Ankern oder Spreizhülsenankern, da diese die Anforderungen dieser Norm nicht erfüllen.
Exécution des travaux géotechniques spéciaux - Tirants d'ancrage
1.1 La présente norme européenne couvre les tirants scellés au coulis dans le terrain qui sont mis en tension et testés. Ils sont soit permanents soit provisoires.
NOTE Pour l’usage de cette norme, le terme de tirant (s) se réfère au terme de tirant (s) d’ancrage
1.2 Les tirants d’ancrages sont conçus conformément à l’EN 1997-1 et testés conformément à la prEN ISO 22477-5.
1.3 Des dispositifs de tirants d'ancrage scellés et à élément de compression sont illustrés à la Figure 1 et la Figure 2.
1.4 Le terme « terrain » englobe à la fois les sols, les roches et les remblais en place préalablement à l’exécution des travaux.
1.5 La conception et le calcul des tirants d'ancrage demandent de l'expérience et une connaissance dans ce domaine.
1.6 La mise en œuvre et les essais de tirants nécessitent une main d'œuvre compétente et qualifiée et une surveillance.
1.7 La présente norme européenne ne saurait se substituer au savoir-faire d'un personnel qualifié et à l'expertise d'entreprises expérimentées, nécessaires à l'application de cette norme européenne.
1.8 Cette norme ne concerne pas les systèmes tels que les pieux en traction, les ancrages vissés, les ancrages mécaniques, les procédés de clouage, les ancrages à corps-morts ou à corps expansifs, puisque ceux-ci ne satisfont pas à la totalité des exigences de cette norme.
Izvedba posebnih geotehničnih del - Geotehnična sidra
Ta evropski standard pokriva talna sidra, zalita v tla, ki se jih obremeni in testira. Lahko so za začasno ali stalno uporabo. Ta sidra so oblikovana v skladu s standardom EN 1997-1 in se jih testira v skladu s standardom prEN ISO 22477-5. Tipična armaturna sidra in sidra na pritisk so prikazana na Sliki 1 in Sliki 2. Izraz »tla« označuje zemljo, skalo ali polnilo, ki je že nameščeno ali obstaja pred začetkom izvedbe gradbenih del. Za načrtovanje in oblikovanje zemeljskih sider so potrebne izkušnje in znanje na tem specializiranem področju. Za namestitev in preskusne faze so potrebni izkušeni kvalificirani delavci in nadzor. Ta standard ne more nadomestiti znanja usposobljenih kadrov in izkušenih podizvajalcev, ki morajo upoštevati ta standard. Ta standard se ne nanaša na sisteme, kot so natezni piloti, vijačna sidra, mehanična sidra, talni žeblji, temelji ali ekspanzijska sidra, ker ne izpolnjujejo zahtev tega standarda.
