Abstract (en)

[origin: WO2018184110A1] Described are an apparatus and method for driving piles prior to lifting and stabilizing foundations that have subsided in unstable ground. A press head, comprising two non-slip arms actuated by a safety lever, is connected to an angle cleat-type foundation piece secured to the foundation by a pair of hydraulic rams in order to drive the piles into the ground as far as the bedrock when the rams contract. The apparatus includes a safety system actuated by the lever for controlling the arms. In order to level the building, other hydraulic rams are installed on each driven pile, all connected in series in order that they may be actuated simultaneously in order to lift the building. When the foundations have been adequately raised and levelled, each pile and the corresponding angle cleat-type foundation piece, both made of steel, are welded in order to stabilize the foundations.
