发明名称 TOOLS AND METHODS FOR CONSTRUCTING LARGE DIAMETER UNDERGROUND PILES
摘要 Methods are provided for the creation of large diameter piles in all types of soils (cohesive, cohesionless or rocky), particularly for the construction of bulkheads made of juxtaposed or secant piles, while maintaining the deviation from the vertical well below the limit @2% required by European standard EN 1536. The invention reduces verticality errors, advantageously exploiting the accuracy provided by the directional drilling technology. Tools for implementing such methods are also provided.
