Tubex® Paal

Vibration-free, soil-displacing concrete pile with permanent steel tube, screwed to depth.

Specifications

Pile dimensions:

Length pile:
In principle, unlimited. The maximum length is generally about 30 m. The pile head can be installed either to ground level or sunken.

Reinforcement:
The piles are provided (if necessary) with prefabricated reinforcement baskets. Depending on the requirements, they are reinforced with head reinforcement or full length.

Concrete:
The piles are (possibly) provided with concrete directly from the plant. All strength classes can be applied here.

Soil mechanical bearing capacity:
NL: The bearing capacity is calculated in accordance with current EC, NEN and CUR standards.
B: The bearing capacity is calculated in accordance with current EC, NBN and CUR standards.

Methods:

  • A steel pipe, equipped with a welded steel drill point, is placed at ground level;
  • The tube is screwed to depth by applying axial pressure and torque;
  • Upon reaching the desired pile tip level, the pile is installed;
  • The rig can be moved to the next pile location; At a later stage, the steel tube will be burned off at the exact height;
  • The reinforcement is inserted into the pipe;
  • The tube is filled with concrete;
  • The pile is now manufactured.


Advantages:

  • Vibration-free, and 100% ground displacement (no relaxation of soil or reduction of cone resistance);
  • No risk of damage to adjoining properties during the manufacture of the pile;
  • Ideally suited for absorbing large compressive and tensile forces, moments and limiting deformations;
  • No noise pollution, like pile driving or vibration. Only noise is the drill motor;
  • No soil removal. Soil is pushed away laterally;
  • Good application in very weak soil layers. Deformation of the pile shaft cannot occur here;
  • Applicable as a temporary foundation pile;
  • Applicable in rooms with limited height or space.

Applicable base:
Tubex piles can be well applied in bases from about 1 to 20 MPa. In places where there are very weak layers, it is possible to opt for this system. If dealing with very heavy layers, it is possible to choose a system with grout injection, such as the Fundex gi pile or the Tubex gi pile.

Inclinations:
Up to 4:1 forward and 1:1 backward. It is also possible to drill up to 3:1 "out of side".

Workspace:
The tubex pile is applicable in both free and restricted height, or space.

Abutments:
Depending on the rig, the piles can be installed at a distance of approximately 0.5 to 0.9 m perpendicular to the abutting wall. In the case of recessed corners, this is of course more.

Executable rigs:
Fundex F10, F12S, F12SE, F15, F16, F2800, F3500.
All Tubex rigs.

Dimensions rigs:
Depending on type rig.
Setup area variable from approximately 2×3 to 9×14 m.
Height variable from approximately 2.5 to 48 m.
Built-up weight variable from about 13 to 120 tons.
