Abstract

To reinforce the ground around the base of a sunken pile, a base body (1) is formed in the ground with a high tensile shrouding (2). The shrouding is filled with a ground material (3) which is compressed progressively by a ram (4). The ram beating action can be combined with vibration to compress and stabilize the filling material in the base body.

Description

Die Erfindung betrifft ein Verfahren zur mechanischen und dynamischen Stabilisierung von Bodenpfählen in Umhüllungen aus Naturtextilien und Kunststofftextilien als Geotextilien. The invention relates to a method for mechanical and dynamic stabilization of ground piles in coatings from natural textiles and plastic textiles as Geotextiles.

Bekannt ist, Sande oder rollige Bodenarten in Bodenlöcher einzufüllen und durch Wasserspülung gleichförmig zu verteilen. Bekannt ist auch, Sande oder rollige Bodenarten in Bohrlöcher einzufüllen und zur Verteilung anzustampfen. Bekannt ist auch, ein verschlossenes Pfahlrohr in einen Boden hineinzuschlagen oder hineinzufibrieren, mit Sand oder rolligen Bodenarten aufzufüllen und endlich mit einem Vibrator das Pfahlrohr wieder herauszuziehen (dabei bleibt der Verschlussdeckel im Boden). Bekannt ist auch, ein verschlossenes Pfahlrohr in einen Boden einzudrücken, einzuschlagen oder einzufibrieren, in das leere Pfahlrohr einen Textilsack einzubringen, diesen mit Sand oder rolligen Bodenarten aufzufüllen und endlich das Pfahlrohr wieder mit einem Vibrator aus dem Boden herauszuziehen (dabei bleibt der Verschlussdeckel im Boden, kann als Verschluss-Klappensystem dauerverwendet verwendbar sein. It is known to have sands or uneven soil in holes to be filled in and uniformly by water rinsing to distribute. It is also known to have sands or rolling soil in Filling holes and pounding for distribution. It is also known to have a closed pile tube in one Pound or vibrate the ground in, with sand or fill up rolling soil types and finally with one Vibrator to pull the pile tube out again (the Cover in the floor). It is also known to be a press the sealed pile tube into a floor, to hammer or to vibrate into the empty pile tube Textile sack to bring in, this with sand or rolling Fill up soil types and finally use the pile tube again pull a vibrator out of the ground (it stays that way the cover in the bottom, can be used as Locking flap system can be used continuously.

Bei allen vorgenannten Verfahren wird das eingefüllte Bodenmaterial nur so weit verteilt, dass keine Hohlräume verbleiben, eine Stabilisierung zur Aufnahme hoher Auflastkräfte wird nicht erreicht. Selbst der indirekte Einfluss einer Vibration über ein Pfahlrohr erzielt nur eine relativ lockere Lagerung des eingefüllten Bodenmaterials, dieses Material wird durch die Vibration nicht direkt beaufschlagt. Bei einer lockeren Lagerung eines Sandes mit einem Porenraum über 40% der Poren, total mit Wasser aufgefüllt, ist der Sand in der Umhüllung immer instabil und damit verbunden mit drückenden Auflasten bleibend beliebig verformbar. Sand in Umhüllungen ist dann nicht standstabil, die Umhüllungen knicken ein (krumme Knie) und sind dann nur noch diffus Kräfte abtragend. In all of the above methods, the filled in Floor material only distributed so far that no voids remain, a stabilization to absorb high Load forces are not reached. Even the indirect influence vibration through a pile tube only achieves a relative one loose storage of the filled soil material, this Material does not become direct due to the vibration applied. If sand is stored loosely with a Pore space over 40% of the pores, completely filled with water, the sand in the coating is always unstable and therefore combined with pressing loads remaining arbitrary deformable. Sand in coatings is then not stable Envelopes bend (bent knees) and are then only still diffusely transferring forces.

Erfindungsgemäss werden vorgenannte Mängel dadurch ausgeschlossen, indem Bodenmaterialien in eine hochfeste standstabile Umhüllung hoch kompaktiert eingebaut werden. According to the invention, the aforementioned defects are thereby excluded by putting flooring materials in a high strength stable wrapping can be installed highly compact.

Erfindungsgemäss erfolgt der hoch kompaktierte Einbau durch statischen und dynamischen Druck direkt auf das in eine hochfeste Umhüllung eingebaute Bodenmaterial. According to the invention, the highly compact installation is carried out by static and dynamic pressure directly on the one high strength wrapping built in floor material.

Erfindungsgemäss erfolgt der hoch kompaktierte Einbau durch Schlagdynamik mit einem Fallgewicht direkt auf das in eine hochfeste Umhüllung eingebaute Bodenmaterial. According to the invention, the highly compact installation is carried out by Impact dynamics with a drop weight directly onto that in one high strength wrapping built in floor material.

Erfindungsgemäss erfolgt der hoch kompakt erte Einbau durch Vibrations-Schlagdynamik mit einem Vibrator als Kreisschwinger oder Wechselschwinger direkt auf das in eine hochfeste Umhüllung eingebaute Bodenmaterial. According to the highly compact installation is carried out by Vibratory impact dynamics with a vibrator as Circular oscillators or alternating oscillators directly on the in a high-strength Wrapping built-in floor material.

Erfindungsgemäss wird die hochfeste Umhüllung in weiche Bodenkörper direkt eingedrückt und dabei mit Bodenmaterial aufgefüllt. According to the high-strength coating in soft Soil body pressed in directly and with floor material refilled.

Erfindungsgemäss wird die hochfeste Umhüllung in Bodenbohrlöcher direkt eingebaut. According to the high-strength coating in Floor boreholes installed directly.

Erfindungsgemäss wird die hochfeste Umhüllung durch führende Verdrängungsrohre in Bodenkörper eingebaut und dabei mit Bodenmaterial aufgefüllt. According to the high-strength coating is through leading displacement pipes installed in the floor and with it Padded floor material.
