Large diameter bored pile
In the event of high loads on major works that justify the mobilization of equipment, the type of piling currently more
suitable is the Large Diameter Pile cast "on site", with mechanical drilling rotation, and also with the possible use of
bentonite slurry
The use of this kind of pile has been largely spread because of its easier and speedier implementation, and its adaptability
to different terrains as well as its immediate visual material gathering. The large diameter piles performed with drilling
can be done near existing buildings, due to its total absence of vibration, and can reach depths of up to 70 meters
It should also be remembered that the large diameter bored piles can be performed in the presence of water depth, which
occurs in marine works and bridge constructions. In this case, the mechanical excavation and underwater concreting are
preceded by penetration of metal casing, generally with the use of vibratory hammer. The equipment, when required, shall
be erected on a floating platform (flat deck barges). The metal liners may be lost or recovered
