Description
Spülrohr mit Spülkopf zum Einspülen von Pfählen Gegenstand der Erfindung ist ein neuartiges Spülrohr mit Spüldose zum Einspülen von Rammpfählen und Spundbohlen, zum Absenken von Brunnen u.,dgl.Flushing pipe with flushing head for flushing piles is the subject of the invention is a new type of flushing pipe with flushing can for flushing driven piles and sheet piles, for lowering wells and the like.
Ganz allgemein ist -der Zweckdes Spülverfahrens der, den von den Pfählen beim Einrammen zu verdrängenden Boden vorher zu beseitigen. --. Bei dieser Beseitigung sind zwei getrennte Hauptvorgänge zu unterscheiden, und zwar: i. das Lösen und Freispülen des Bodens durch die Spüldose .und 2. das Hochspülen oder Auswerfen des derart gelösten Bodens an die Erdoberfläche. Bei -dem bekannten Spülverfahren, wobei die Spüleinrichtung gewöhnlich nur aus einem Druckrohr mit- Spüldose .besteht, bleibt der Hauptarbeitsvorgang, nämlich das Hochbefördern des gelösten Bodens, mehr dem Zufall überlassen, indem das nach Verlassen der Spüldüse sich -in seiner Richtung umsetzende und daher nur noch wenig unter Druck stehende Wasser sich im Sinne einer O_nelle mühsam einen Weg nach der Erdoberfläche bahnen muß und infolge der großen Reibungswiderstände im Boden und je nach Art der Bodenschichtung ein nennenswertes Mitreißen des in der Tiefe gelösten Bodens nicht eintritt. Um diesem Mangel abzuhelfen, soll gemäß der Erfindung das eingeführte Dr uckwasser nicht nur als Spülmittel, sondern -und darin besteht das Neuartige der Erfindung -gleichzeitig auch in erhöhtem Maße als Fördermittel benutzt werden, -indem nach oben gerichtete starke Förderstrahlen !das an der Düse gelöste und in einem breiigen Zustand versetzte Spülgut nach oben auswerfen. Zu diesem Zweck ist, wie aus der Zeichnung ersichtlich, Idas Spülrohr mit Rippen 2 versehen, welche die vorher gelösten Bodenschichten dauernd streifenartig zerschneiden und bei ;dem ständigen Bewegen des Spülrohres in steter Lockerung halten. Die zwischen den Rippen z liegenden Rillen bilden für die aus den oberen Spülöffnungen i des Spülkopfes austretenden Förderstrahlen klar vorgezeichnete, wirksame Förderkanäle, wobei außer dem vom -Spülkopf gelösten Boden auch der sonstige längs des Rohres anstehende Boden mit ausgeworfen wird, also längs des Rohres sich loser, lockerer Boden befindet, der auch das so oft vorkommende, lästige Festrammen des Spülrohres verhindert.In general, the purpose of the flushing process is that of the piles remove soil to be displaced when driving in beforehand. -. With this elimination There are two main processes to be distinguished, namely: i. loosening and flushing the floor through the flushing can. and 2. the flushing up or ejection of the dissolved Soil to the surface of the earth. In the known flushing process, the flushing device usually only consists of a pressure pipe with flushing can, the main work process remains, namely the lifting of the loosened soil, left more to chance by that after leaving the flushing nozzle-converting in its direction and therefore only Water that is still under little pressure is laboriously reconciling itself in the sense of an o_nelle Must make way to the surface of the earth and because of the great frictional resistance in the soil and, depending on the type of soil stratification, significant entrainment of the in the depth of loosened soil does not enter. In order to remedy this deficiency, according to the invention, the introduced pressurized water not only as a detergent, but -and this is what is new about the invention - at the same time to a greater extent than Conveying means are used, -by upwardly directed strong conveying jets! The Eject items that are loosened at the nozzle and left in a mushy state upwards. For this purpose, as can be seen from the drawing, Idas flush pipe with ribs 2, which cut the previously loosened soil layers continuously in strips and with the constant movement of the flushing pipe, keep it in constant relaxation. The between the ribs z forming grooves for the from the upper flushing openings i des Clear, effective conveying channels, in addition to the soil loosened from the flushing head, the other soil along the pipe pending soil is also ejected, so along the pipe it becomes looser, looser Floor is located, which also the so often occurring, annoying ramming of the flush pipe prevented.
