Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Brunnenbohr-und Pfahllöchern.
Zur Herstellung von Pfahllöchern und Brunnenbohrungen verwendet man erstens Bohrgeräte, welche das Erdreich aus dem Bohrrohr ausbohren, was aber besonders bei der Herstellung von Betonpfählen den Nachteil hat, dass keine Verdichtung des Bodens unter der Pfahlspitze entsteht, zweitens Vortreibrohre mit einem durch das Rohrinncre gehenden Kern, der unten eine Spitze besitzt, welche Rohre wieder ausgezogen, oder, falls sie ohne Kern wieder eingetrieben
EMI1.1
Erfahrungsgemäss ist dies nur durch schwere teure Rammschienen zu erzielen, welche erhebliche Transportaufstellungskosten und Betriebskosten verursachen und infolge der weitausladenden Fusskonstruktion und der für gewisse Fallhöhen erforderlichen Nutzhöhe nicht auf jeder Baustelle zu verwenden sind.
Verwendet man dagegen zum Einrammen eines Vortreibrohres eine in dessen Hohlraum stehende, von einem Bär belastete oder gerammte Säule aus plastischem Material, wie : Zemellt-,
EMI1.2
Bodenschichten fort. Die bisher üblichen Rammen sind sehr schwer, teuer, schwierig zu transportieren, aufzustellen und zu betätigen. Die Rammeinrichtung für die vorliegende Erfindung hingegen kann ausserordentlich einfach und billig hergestellt werden, weit das Innere des Eintn, ib- rohres dem Bär selbst als Führung dienen kann und die Mäkler an den Rammen ersetzt.

vermieden werden.
Als Ramm- und Ausziehgerüst für das Rohr kann beispielsweise ein Dreibock d vorgesehen werden, der oben eine Laufrolle r für das Bärseil oder eind Vorrichtung zum anbringen der Ramm- und Aufziehvorrichtungen haben kann.
Zur Erleichterung des Eindringens des Rohres in den Boden kann das untere Ende des Vortreibrohres in geeigneter Weise geformt sein.

Method of making well drilling and pile holes.
For the production of pile holes and well bores, firstly, drilling devices are used, which drill the earth out of the drill pipe, but this has the disadvantage, especially in the production of concrete piles, that no compaction of the soil occurs under the pile tip, and secondly, jacking pipes with a core going through the inside of the pipe which has a point at the bottom, which tubes are pulled out again, or, if they are without a core, driven in again
EMI1.1
Experience has shown that this can only be achieved with heavy, expensive ramming rails, which cause considerable transport installation costs and operating costs and, due to the extensive foot construction and the usable height required for certain drop heights, cannot be used on every construction site.
If, on the other hand, you use a pillar of plastic material, such as: Zemell,
EMI1.2
Layers of soil. The hitherto common rams are very heavy, expensive, difficult to transport, set up and operate. The ramming device for the present invention, on the other hand, can be produced extremely simply and cheaply, as long as the inside of the Eintn, ib- pipe can serve as a guide for the bear itself and replaces the brokers on the rams.
EMI1.3
be avoided.
A tripod d, for example, can be provided as a ramming and pulling frame for the pipe, which can have a roller r for the bear rope or a device for attaching the ramming and pulling devices.
In order to facilitate the penetration of the pipe into the ground, the lower end of the propulsion pipe can be shaped in a suitable manner.
