Geotechnical investigation and testing - Field testing - Part 15: Measuring while drilling (ISO 22476-15:2016)
ISO 22476-15:2016 specifies the technical principles for measuring equipment requirements, the execution and reporting on the parameters of the investigation drilling process for geotechnical purposes.
It is applicable to top-driven, destructive drilling methods performed by a fully hydraulically powered drill rig and driving device. It is commonly used with destructive drilling techniques but can also be used with core drilling.
The recording of the drilling parameters during soil grouting, drilling of nails, anchors or piles are beyond the scope of ISO 22476-15:2016.
Geotechnische Erkundung und Untersuchung - Felduntersuchungen - Teil 15: Aufzeichnung der Bohrparameter (ISO 22476-15:2016)
Dieser Teil von ISO 22476 behandelt die technischen Grundlagen für die Anforderungen an Messausrüstung, die Durchführung und die Protokollierung der Parameter des Bohrprozesses für geotechnische Zwecke.
Die Norm gilt für destruktive Bohrverfahren mit Kraftdrehkopf, die mit einem Bohrgerät und einer Bohrvorrichtung, vollständig hydraulisch angetrieben, durchgeführt werden. In der Regel werden diese Verfahren mit destruktiven Bohrtechniken angewandt, die Kernbohrung kann jedoch auch zum Einsatz kommen.
Die Aufzeichnung der Bohrparameter während des Verpressens des Bodens oder des Bohrens von Nägeln, Ankern oder Pfählen fällt nicht in den Anwendungsbereich dieses Teils von ISO 22476.
Reconnaissance et essais - Essais de sol - Partie 15: Enregistrement des paramètre de forages (ISO 22476-15:2016)
La présente partie de l'ISO 22476 traite des principes techniques pour la définition des exigences applicables à l'équipement de mesure ainsi que la mise en œuvre et la consignation des paramètres du processus de mesure en cours de foragedans le cadre de reconnaissances géotechniques.
Elle s'applique aux méthodes de forage destructif entraînées par le haut et réalisées par une machine de forage et un dispositif de forage entièrement hydrauliques. Elle est habituellement mise en œuvre avec les techniques de forage destructif mais peut également être utilisée dans le cadre d'opérations de carottage.
L'enregistrement des paramètres de forage pendant l'injection de ciment dans le sol ou le forage pour la réalisation de clous, ancrages ou pieux n'entre pas dans le cadre de la présente partie de l'ISO 22476.
Geotehnično preiskovanje in preskušanje - Preskušanje na terenu - 15. del: Meritve ob vrtanju (ISO 22476-15:2016)
Ta standard določa tehnična načela za zahteve merilne opreme, izvedbo in poročanje o parametrih postopka raziskovalnega vrtanja za geotehnične namene. Metoda meritve ob vrtanju (MWD) obravnava beleženje parametrov stroja med postopkom vrtanja. To je mogoče narediti ročno ali z uporabo računalniških sistemov, ki spremljajo niz senzorjev, nameščenih na rotacijsko in/ali udarno opremo za vrtanje. Ti senzorji neprekinjeno in samodejno zbirajo podatke o vseh vidikih vrtanja v realnem času, ne da bi ovirali napredovanja vrtanja. Podatki so prikazani v realnem času in se tudi beležijo za nadaljnje analize.
