Description
Bei der Herstellung von lotrechten oder waagerechten Grundwasserfassungsanlagen, wie Rohrfiltei-brunnen oder Sickergalerien, beispielsweise bei Grundwasserabsenkungen, werden zur Erzielung der Sandfreiheit des zu fördernden Wassers um das eingebaute Filter- oder Brunnenrohr je nach den anstehenden Bodenschichten Kiesschüttungen, bisweilen in mehrfachen Abstufungen, eingebracht. Diese Kiesschüttungen verursachen einen bedeutend größeren Bohrdurchmesser, als für die Erschließung des Grundwassers nötig ist; sie sind somit unwirtschaftlich.In the production of vertical or horizontal groundwater catchment systems, such as pipe filter wells or drainage galleries, for example in the event of lowering of the groundwater level, are built to achieve the sand-free water to be pumped around the Filter or well pipe, depending on the existing soil layers, gravel fillings, sometimes in multiple gradations, introduced. This causes gravel piles a significantly larger drilling diameter than for the development of the groundwater is necessary; they are therefore uneconomical.
Bei anderen bekannten Ausführungen dieser Art wurden zur Erzielung von Sandfreiheit des zu fördernden Wassers Filterrohre mit Gewebeumhüllung eingebaut. Dabei entspricht der Bohrdurchmesser ungefähr dem Filterrohrdurchmesser. Um eine solche Fassung sandfrei zu bekommen, mußten aber durch umfangreiche Pumparbeiten die feinen Sande dem Boden entzogen werden. Außerdem ist es hierbei nachteilig, daß die Gewebe mit dem der Maschenweite entsprechenden Korn sich zusetzen.In other known designs of this type were to achieve The water to be pumped is free of sand. Filter pipes with fabric cover are installed. The drilling diameter corresponds approximately to the filter tube diameter. To a To get such a setting sand-free, however, had to be through extensive pumping work the fine sands are withdrawn from the ground. It is also disadvantageous here that the fabric with the grain corresponding to the mesh size is clogged.
Auch bei den Horizontalbohrungen wird versucht, durch Auspumpen von Fein- und Mittelsanden eine Sandfreiheit zu erreichen. Dabei werden aber beträchtliche Sandmengen dem Untergrund entnommen, so daß die Gefahr von Setzungen und der Bildung von Hohlräumen besteht.Attempts are also being made with the horizontal bores by pumping out Fine and medium sands to achieve freedom from sand. But this will be considerable Amounts of sand removed from the subsoil, so that there is a risk of subsidence and formation consists of cavities.
Die Erfindung hat sich zur Aufgabe gemacht, alle diese Nachteile der bekannten Grundwasserfassungsanlagen, wie insbesondere unwirtschaftlichen Bohrdurchmesser, das Zusetzen der Gewebe bzw. Schlitzöffnungen, ferner aber auch Sandführungen sowie jeden Sandentzug zu vermeiden.The invention has set itself the task of eliminating all of these disadvantages known groundwater catchment systems, such as, in particular, uneconomical drilling diameters, the clogging of the tissue or slot openings, but also sand guides as well to avoid any withdrawal of sand.
Dies wird erfindungsgemäß dadurch erreicht, daß als Filtermaterial Glaswolle, Steinwolle oder ein ähnliches mineralisches Wollprodukt verwendet wird.This is achieved according to the invention in that as a filter material Glass wool, rock wool or a similar mineral wool product is used.
Der Wert der Erfindung liegt darin, ein Material gefunden zu haben, das vollkommen wasserdurchlässig ist, dabei aber alle festen Bestandteile, wie insbesondere Sand bei äußerst geringer Stärke der Filterschicht, zurückhält. Ein Zusetzen des Filterkörpers findet infolge der besonderen Eigenart dieses Filtermaterials nicht statt. Außerdem kann der Bohrdurchmesser dem Filterrohrdurchmesser angeglichen werden. Es sind somit alle Nachteile der bisherigen Grundwasserfassungsarten vermieden.The value of the invention lies in having found a material that is completely water-permeable, but all solid components, such as in particular Sand with extremely low thickness of the filter layer. A clogging of the Due to the special nature of this filter material, there is no filter body instead of. In addition, the drilling diameter can be adjusted to the diameter of the filter tube. All the disadvantages of the previous types of groundwater catchment are thus avoided.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.The drawing shows an embodiment of the subject matter of the invention shown.
Der Vorteil der neuen Ausführung gegenüber der üblichen Filterkiesschüttung besteht vor allem darin, daß bei gleichen Durchmessern der Filter C der Bohrdurchmesser B bei der neuen Ausführung mit Mineralwolle D bedeutend kleiner gewählt werden kann als der Bohrdurchmesser bei Anwendung der bekannten Filterkiesschüttung.The advantage of the new design compared to the usual filter gravel bed consists mainly in the fact that, with the same diameter, the filter C is the drilling diameter B can be chosen significantly smaller in the new version with mineral wool D. than the drilling diameter when using the known filter gravel bed.
In Zahlen ausgedrückt würde beispielsweise bei einem einheitlichen Filterrohr von 300 mm Durchmesser bei Verwendung der Mineralwolle der Bohrdurchmesser etwa 355 mm betragen, während derselbe bei der bisher üblichen Ausführung mit Filterkiesschüttung einen Durchmesser von etwa 5oo bis 6oo mm aufweisen müßte.Expressed in numbers, for example, with a uniform filter tube of 300 mm diameter using mineral wool, the drilling diameter would be about 355 mm, while the same would have to have a diameter of about 500 to 600 mm in the conventional design with filter gravel bed.
