Title:
IMPROVED CONCRETE PILE MADE OF SUCH A CONCRETE AND METHOD FOR DRILLING A HOLE ADAPTED FOR RECEIVING THE IMPROVED CONCRETE PILE IN A WEAK GROUND
Document Type and Number:
WIPO Patent Application WO2002077136
Kind Code:
A3
Abstract:
The invention relates to a device for reinforcing a ground, comprising a series of structural inclusions disposed in the ground, the inclusions having a diameter D comprised between substantially 0.2 m and 0.6 m, two adjacent inclusions being separated by a distance (A) such as 2D - A - 10D, said series of inclusions being made of a material having a Young modulus comprised between 500 and 10 000 MPa, a load transmitting layer interposed between the ground and the loading structure, said layer having a Young modulus less than the Young modulus of the series of inclusions, a first nominal height between two adjacent inclusions of said series, and a second height less than the first nominal height at locations situated just above the series of inclusions, where the load transmitting layer is plastically compressed by the inclusions which partially penetrate within said load transmitting layer.
