^Tubex® pile grout injection

pile dimensions:
Standard dimensions are: 

A grout sleeve with the same diameter as the drill bit will be installed in the sand layers.

pile length:
In principle, unlimited. The pile head can be installed either at ground level or below ground level.

Reinforcement:
The piles (if necessary) fitted with prefabricated reinforcement cages. Depending on the requirements, they are reinforced at the top or along their entire length.

Concrete:
The piles (if necessary) cast in concrete directly at the plant. All strength classes can be used for this purpose.

Soil-bearing capacity:
EN: The bearing capacity is calculated in accordance with current NEN and CUR standards.
The following factors may be applied:
ap = 0.63
ß = 1.0
s = 1.0
as = 0.009
at = 0.009
B: For questions regarding load-bearing capacity, please contact our office.

Procedure:

• A steel pipe, fitted with a welded steel drill bit, is placed at ground level;
• The pipe is driven to the desired depth by applying axial pressure and torque while injecting a grout mixture;
• Once the desired pile tip elevation has been reached, the pile is pile ;
• The rig be moved to the next pile location;
• At a later stage, the steel tube is cut to the exact height;
• The reinforcement is installed inside the pipe;
• The pipe is filled with concrete;
• The pile now pile manufactured.

Advantages:

• Vibration-free and 100% soil-displacing (no soil loosening or reduction in cone resistance);
• No risk of damage to adjacent properties during pile construction;
• A very high load capacity is permitted;
• Ideal for absorbing large compressive and tensile forces and moments, and for limiting deformation;
• No noise pollution, unlike with pile driving or vibration. The only noise is the drill motor;
• No soil removal. Soil is pushed aside;
• Suitable for use in virtually all soil types;
• Suitable for use in areas with limited headroom or space;
• Capability to drill through masonry, cracked concrete, and existing wooden piles.

Suitable soil conditions:
Tubex piles grout injection are well-suited for use in very heavy soils with cone values up to approximately 80 MPa. In areas with very heavy soil layers, this system is a viable option because the pile tip level can be guaranteed. If you have any doubts regarding feasibility, please feel free to contact our office.

Drilling angles:
Up to 4:1 forward and 1:1 backward. It is also possible to drill up to 3:1 “sideways.”

Application:
The tubex pile grout injection can be used in both open and confined spaces.

Adjacent Structures:
Depending on the rig, the piles can be piles at a distance of approximately 0.5 to 0.9 m perpendicular to the adjacent structure. At recessed corners, this distance is naturally greater.
