Upon reaching the bearing layer – or upon sufficiently penetrating soil strata in the case of friction pile design – a reinforcing cage is suspended within the mandrel, and concrete is placed. Water is injected through the drill-point around drillpoint and drill-tube. Different pitch lengths can be used on the auger flighting depending upon the anticipated soil conditions: Due to the full soil displacement, the pile system is also highly suitable for use in contaminated locations. There is no central tendon required, and concrete is not soil mixed, but rather pure structural concrete.

The Fundex pile is a true full section cast in place reinforced concrete pile, installed by torque and down pressure, completely free of vibration and with no piledriving noise.
FUNDEX PILES « Le Monde International Drilling Equipment
The Fundex pile can lile installed to a maximum rake of 1 in 3. It is available in two sizes with shank diameters of 38 cm or 44 cm and load bearing capacities of up to kN depending on the existing subsoil. The impact hammer is brought to the top of the leads and a special center hole pipe vibratory hammer is used pi,e simultaneously pull the casing.
Due to the low-noise application, funddex inhabitants are not disturbed by unnecessary construction noise. Because the tip can be fitted to the mandrel with a waterproof caulking, there is no concern of soil or groundwater entering the pile mandrel prior to the completion of the pile. To change the direction, the device is lifted from the ground, the moving mechanism is rotated in the new direction and the process is repeated after lowering it.
Upon reaching the bearing layer – or upon sufficiently penetrating soil strata in the case of friction pile design – a reinforcing cage is suspended within the mandrel, and concrete is placed. Sprachauswahl – Select language deutsch english. The mandrel is installed by using torque and down-pressure, producing veryJow noise levels and no vibration.

When the foundation level is reached, the reinforcement is placed over the anchorcage in the pilepoint, which guarantees sufficient anchor length. A sacrificial boot-plate is fitted to a driving mandrel. While the operation appears similar to a drilling job, the patented Fundex tip displaces the soil laterally, bringing no spoils to the ground surface. The drill point is positively connected to the tube through a corresponding tooth, such that a jointing compound laid on the tooth seals the tube tightly from groundwater seepage.
With the help of bayonet joint through triple hydro-isolated soft laying the lower end of the thick drilling tube is fastened to the point.
After reaching the required depth. Fundex piles can be constructed at mm from an adjacent building, but in a corner this distances is more.
Quickly executable Extremely high load bearing capacity High peak pressure High skin friction Extremely strong No change in the groundwater balance. The low set-up times, the rapid pile manufacture and the high load-bearing capacity pilw the Fundex pile result in high economic viability and short construction times.
Drill spoil offhaul is virtually eliminated. Different pitch lengths can be used on the auger flighting depending upon the anticipated soil conditions: Further, the effective diameter of the pile is increased to the diameter of the soil-cement column, which is approximately equal to the tip diameter. No danger to adjacent buildings during drilling.
Greatly variable depths across a site are achievable as the mandrel may be stopped at any point “refusal” is encountered. The concrete pump should be sized according to the expected extraction rate of the drill string, the volume of the void created by ffundex displacement tool as it is extracted, and the required pressure range that will be used during the injection of the concrete.
On completion of boring operation, the drilling string and the tool are extracted funde concrete is poured throughout the internal hollow pipe. Different pitch lengths can be used on the auger flighting depending upon the anticipated soil conditions:. The possible diameters and lengths for Fundex piles range from about to mm On pulling the casing pipe by turning it to the left and right, the concrete goes to the bottom of the tube.
Due to the shape of the pilepoint, the Fundexpiles is very suitable for tension piles.
The cast insitu construction of the piles produces a roughened amplitude surface at the pile-to-soil interface, thereby increasing the frictional capacity of the Vibrex piles over precast piles or H-piles. It is a true soil displacement pile over its full pilr length. Fundex piles are usually designed for a 40 to ton service capacity.
Advantages – at a glance. For piles with high tension, Fundexpiles with prestressed steel bars can be applied, also Tubexpiles like Fundex but with permanent casing. Essentially, two types of APGD pil can be constructed:
