Precast reinforced concrete driven pile
Franki Geotechnics B
column prefabricated, beaten in the ground using a diesel or hydraulic hammer
Characteristics:
section of 180x180mm ² until 450x450mm ²
standard length until 28m
quality of concrete >C45/55
not flexible (length not adaptable to the conditions of the ground)
considering the prefabrivation, the configuration and the loads must be known at least 4 weeks in advance
length not adaptable to the conditions of the ground: (risk of the piles too short and too long) the soil surveys must be relatively homogeneous.
possible control thanks to the test of integrity (cracking)
Scope of application:
permits to beat
complexes industrial
typically Dutch characteristics of ground: a very loose layer of dixaine of meters (<0.3MPa) and àprès a compact layer of sand. With piles préfab certainty to aivoir continuous concrete until the ground level.
