Geotechnical investigation and testing - Geohydraulic testing - Part 4: Pumping tests (ISO 22282-4:2012)

ISO 22282-4:2012 establishes requirements for pumping tests as part of geotechnical investigation service in accordance with EN 1997-1 and EN 1997-2.
ISO 22282-4:2012 applies to pumping tests performed on aquifers whose permeability is such that pumping from a well can create a lowering of the piezometric head within hours or days depending on the ground conditions and the purpose. It covers pumping tests carried out in soils and rock.
The tests concerned by ISO 22282-4:2012 are those intended for evaluating the hydrodynamic parameters of an aquifer and well parameters.

Geotechnische Erkundung und Untersuchung - Geohydraulische Versuche - Teil 4: Pumpversuche (ISO 22282-4:2012)

Dieser Teil von ISO 22282 behandelt Anforderungen an Pumpversuche als Teil der geotechnischen Erkundung nach EN 1997 1 und EN 1997 2.
Grundsätzlich besteht ein Pumpversuch aus Folgendem:
-   Druckabsenkung durch Abpumpen von Wasser aus einem Brunnen (dem Versuchsbrunnen);
-   Messen des abgepumpten Volumens und des Wasserspiegels im Versuchsbrunnen und in den Grundwassermessstellen vor, während und nach dem Pumpen als Funktion der Zeit.
Dieser Teil von ISO 22282 gilt für Pumpversuche in Grundwasserleitern, deren Durchlässigkeit so ist, dass das Abpumpen aus einem Brunnen - in Abhängigkeit von den Bedingungen des Baugrunds und dem Zweck - zu einer Absenkung der piezometrischen Höhe innerhalb von Stunden oder Tagen führt. Das Dokument behandelt Pumpversuche in Locker- und Felsgestein.
Bei den durch diesen Teil von ISO 22282 abgedeckten Versuchen handelt es sich um diejenigen, die zur Auswertung der hydrodynamischen Parameter eines Grundwasserleiters und von Brunnenparametern vorgesehen sind, z. B.:
-   Allgemeiner Durchlässigkeitsbeiwert des Grundwasserleiters;
-   Einflussradius des Pumpens;
-   Förderrate für einen Brunnen;
-   Auswirkung in Bezug auf die Absenkung in einem Grundwasserleiter während des Pumpens;
-   Skin Faktor;
-   Brunnenspeicherkoeffizient;
-   Auswirkung in Bezug auf die Wiederherstellung in einem Grundwasserleiter nach dem Pumpen.

Geotehnično preiskovanje in preskušanje - Hidrogeološke preiskave - 4. del: Črpalni preskus (ISO 22282-4:2012)

Ta del standarda ISO 22282 vzpostavlja zahteve za preizkuse črpanja kot del geotehničnih raziskovalnih storitev v skladu s standardoma EN 1997-1 in EN 1997-2. Preizkus črpanja sestavljata predvsem: – spuščanje piezometrične površine podtalnice s črpanjem iz vrtine (preizkusne vrtine); – merjenje pretoka črpanja in ravni vode v preizkusni vrtini in piezometrih pred in med črpanjem ter po njem, v časovni odvisnosti. Ta del standarda ISO 22282 velja za preizkuse črpanja, izvedene v vodonosnikih, katerih propustnost je tolikšna, da lahko črpanje iz vrtine povzroči znižanje piezometrične gladine v nekaj urah ali dneh, odvisno od pogojev tal in namena. Pokriva preizkuse črpanja, izvedene v prsti in kamninah.
