Large diameter Drilled Shafts
The Large Diameter Drilled Shafts are the solution most commonly used for offshore foundation of ports, bridges, and piers, using lost or recovered metallic casing.
OFFSHORE DRILLED SHAFTS ARE MADE THE USE OF HYDRAULIC DRILLING RIGS AND REVERSE CIRCULATION SYSTEM
In offshore drilled shafts, the mechanical excavation and underwater concreting are preceded by the insertion of a steel casing, generally with the use of a hydraulic or vibratory hammer. The drilling rig, when required, shall be setup on a fixed leg platform or a flat deck barge.
With special equipments, the drilled shafts can reach depths of up to 330ft (100m).
Brasfond conducts special foundations projects in the presence of water depth by Brasfix (Brasfix Fundações de Obras Marítimas e Fluviais), established in 2000 to meet challenging projects with a high level of performance.
