Precast driven piles (concrete)

Vroom Funderingstechnieken has accumulated a lot of experience in precast driven piles and provides advice on their applications. The pile system displaces soil. Vroom specializes in heavy, large-sized precast driven piles.

Application

  • Wind turbine foundations.
  • Residential construction, commercial construction, and all other types of structures in nearly any soil condition.
  • Projects in civil engineering and hydraulic engineering involving high pile loads.
  • Can be inserted from the existing ground level into basements, tunnels and other underground structures, then driven deeper.
  • Piling from a pontoon on the water for boat sheds, docks and bridges.
  • Storage spaces, underpinned terraces and garden walls in new construction projects.

Features

  • Traditional pile system that can be applied to virtually all construction works.
  • The pile head can be driven to the desired height in case of feed fields.
  • Penetration depth is well controllable through calendaring.
  • Due to large orders from suppliers, flexible in handling changes to pile specifications.
  • Bracing angles: backward up to a maximum of 4:1 / forward up to a maximum of 5:1.
  • Capable of bearing compressive, tensile, and moment loads with additional reinforcement.

Piles are primarily driven with hydraulic hammers, allowing for precise adjustment of impact energy. The driving process is controlled to ensure the safety of both the pile and its surroundings.

Quality Control

Vroom Funderingstechnieken installs precast driven piles according to an execution procedure established by Vroom Funderingstechnieken as part of internal quality control and nationally applicable standards.

Geotechnical Bearing Capacity Check

During the driving of precast driven piles, the bearing capacity can be verified through calendaring.

Pile Technical Bearing Capacity Check

Precast driven piles can be acoustically inspected for continuity after driving.

Technical data

Hydraulic Hammers

Junttan HHK 2.5, 3, 4, 5, 6, 9, and 12a.

Diesel Hammers

Various types of diesel hammers can be used.

Concrete Quality

Minimum C45/55 XC2.

Reinforcement

The piles are prestressed and reinforced with prestressing steel. Additional traditional reinforcement can be applied for tension or moments.

Bearing Capacity

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

Pile Point Bearing Capacity Factors

αp = 0.7
β = 1.0

Shaft Friction Factor

αs = 0.010
Tension: αt = 0.007

Load and Deformation Behavior

In accordance with Eurocode 7 (NEN 6743, type 1, figures 6 and 7), depending on the soil condition.

Load Spectrum

Compression up to approximately 5000 kN
Tension up to approximately 600 kN.

Structural Aspects

Available standard dimensions of precast driven piles, square sizes in mm:

  • 220
  • 250
  • 290
  • 320
  • 350
  • 380
  • 400
  • 420
  • 450
  • 500

The maximum pile length is approximately 80 to 90 times the square dimension.
Application depends on the soil condition and drivability.
Precast driven piles can also be supplied with a reinforced base and/or with internal or external ribbed profiles.
Precast driven piles can also be supplied with couplings.
