Vibro-SD piles

The in-ground formed and soil-displacing vibro-SD (Small Diameters) piles can be used under floors in industrial halls and under pile mattresses. The combination of pile and floor can lead to an economical design. The vibro-SD piles are installed at a very high production rate.

Application

  • Vibro-SD piles are well-suited for variable soil conditions as the pile length can be adjusted on-site under the given circumstances.
  • The production process of vibro-SD piles is fully automated.
  • In floor fields, the designer can opt for a dense pile field combined with a thin floor field with relatively little reinforcement.
  • Vroom Funderingstechnieken can provide both the vibro-SD piles for the floor fields and the structural piles for a main support structure.
  • Vibro-SD piles are also applicable in ‘mattresses’ for the foundation of roads and terrains.
  • In combination with earthwork, settlement-resistant road constructions can be offered.
  • In some situations, vibro-SD piles can also be used for structures. However, it should be taken into account that there is a limited possibility to reinforce.

Features

  • The pile head is poured up to the working level and finished at the working level to the desired height.
  • Pile length can be immediately adjusted to the ground conditions.
  • High production speed: a large number of piles per day.
  • Suitable for concentric compression loading: larger diameters and limited suitability for eccentric loads.
  • The system is low in vibration and noise.
  • The system is soil displacing, so no excavated soil.
  • Pile system and bearing capacity factors are in accordance with Eurocode 7 (NEN 6743 in-ground formed pile vibrated drawn).

Vibro-SD piles are a cost-effective and logistically interesting addition to traditional and in-ground formed pile systems. The foundation piles are realized at a high production rate. A casing tube is vibrated to depth in the ground. Given the required high production speeds, smaller diameters and lengths are preferred.

For floor fields in industrial halls, a well-thought-out pile plan ensures an even distribution of the floor load.

For larger diameters and pile lengths, or 'construction' piles for a commercial building, other pile systems are available. For floor fields in industrial halls, a well-thought-out pile plan ensures an even distribution of the floor load.

Quality Control

Vroom Funderingstechnieken manufactures vibro-SD piles according to its own execution procedure established as part of internal quality control and nationally applicable standards. Vibro-SD piles produced by Vroom Funderingstechnieken can optionally be acoustically measured and then assessed by an independent advisory bureau. Thanks to its own quality control, appropriate responses can be made in case of doubts about pile quality or client requests regarding execution.

Technical data

Concrete Quality

C20/25, C25/30, and C30/37 quality.

Reinforcement

B500B quality.

For centric loading, standardly equipped with a reinforcement bar in the pile head, with a diameter of 16 mm and a length of 1.5 meters.

For eccentric loading, a short reinforcement cage is used, which is inserted after manufacturing.

Additional or different reinforcement depends on the load to be absorbed.

Bearing Capacity

The geotechnical bearing capacity according to Eurocode 7 (NEN 6743) provides as pile class factors:

Pile Tip Bearing Capacity Factor

αp = 0.70
β = 1.0 for standard SD piles with a sealing plate

Shaft Friction for Pressure Piles

αs = 0.012 (vibrated drawn tube)

Additional provisions in the calculation of pile bearing capacity are not applicable.

Load-Deformation Behavior

In accordance with Eurocode 7 (type 1 NEN 6743: figure A 34-18 and A 34-19)

Loading Spectrum

Depending on the diameter and soil condition, up to max. 600 kN pressure (calculated value).

Foundation Machine

Machine weight production-ready approx. 80 tons.

Vibratory Block

Continuously adjustable.

Vibro-SD Tube Data

Available tube diameters 180, 220, and 273 mm.

Pile Lengths

Maximum 26 m, depending on the diameter.

Manufacturing

  1. The steel feed tube with a loose cover plate is placed at ground level.
  2. The feed tube is vibrated into place using a high-frequency vibratory block in combination with the pull-down of the foundation machine. During insertion, concrete is pumped into the tube.
  3. When the desired level is reached, concrete is introduced into the feed tube until the desired pressure in the tube is present.
  4. The tube is filled with concrete and pressurized so that the pulling of the tube can start.
  5. Under a preset pressure, the tube is automatically vibrated out. During the extraction, concrete mix is continuously and pressurized supplied. The pile diameter is controlled in an automated production process where pulling speed, concrete pressure, and concrete volume are coordinated.
  6. The foundation machine is moved, the pile head finished, and if necessary equipped with head reinforcement.
