Description

Verfahren zur Herstellung von Betonpfählen innerhalb von Hülsen aus dünnwandigen leichten Stoffen, wie Pappe, Papier, Holzstoff o. dgl. Das Verfahren, Ortpfähle aus Beton innerhaib von in die Bohrlöcher eingebrachten Papp- oder Papierrohren herzustellen, ist bekannt. Aus wirtschaftlichen Gründen ist es erstrebenswert, derartige Rohze möglichst dünnwandig zu wählen. Dabei kann es leicht vorkommen, daß diese Rohre den Beanspruchungen beim Einbringen des Betons nicht gewachsen sind und reißen oder platzen. Um dies zu vermeiden, werden gemäß der vorliegenden Erfindung diese Rohre oder Hülsen gegen den Druck des eingebrachten Betons durch entfernbare Stülp- oder Außenrohre abgestützt. Um die Entfernung der Außenrohre zu erleichtern bzw. die Reibung zwischen beiden Rohren zu verringern, können auf der Innenseite der Außenrohre Gleitvorrichtungen, z. B. Gleitröllen, vorgesehen werden. Das Verfahren gemäß der Erfindung läßt sich auch bei außerhalb der Verwendungsstelle auf Vorrat gefertigten Betonpfählen anwenden. In diesem Falle ist es zweckmäßig, die innere Hülse in bekannter Weise aus Hälften zusammenzusetzen, die durch Scharniere oder Riegel miteinander verbunden werden.Process for the production of concrete piles made from within sleeves thin-walled light materials, such as cardboard, paper, wood pulp, etc. The process, Concrete cast-in posts inside cardboard or paper pipes inserted into the boreholes to produce is known. For economic reasons it is desirable to have such Choose raw materials as thin-walled as possible. It can easily happen that this Pipes cannot cope with the stresses caused by pouring the concrete and crack or burst. In order to avoid this, according to the present invention, these Pipes or sleeves against the pressure of the poured concrete by means of removable inverted or outer tubes supported. In order to facilitate or remove the outer pipes. To reduce the friction between both tubes can be done on the inside of the Outer tubes sliding devices, e.g. B. sliding rollers are provided. The procedure according to the invention can also be stored outside the point of use use manufactured concrete piles. In this case it is advisable to use the inner Assemble the sleeve in a known manner from halves by hinges or Bolt are connected to each other.
