The Mega pile is a high-quality alternative to the classic underpinning, applicable in special and difficult working conditions. It is a jacked pile that consists of short cylindrical elements, made from steel or concrete. By excavating underneath a structure, short lengths of pile can be inserted and jacked into the soil with a hydraulic jack, using the underside of the existing structure as a reaction. Construction sequence 1. & 2. The penetration of the segments is obtained by means of a hydraulic jack. 3. During jacking, steel segments are progressively welded together. 4. The jacking operation is continued until the penetration resistance - as shown on the pressure gauge - reaches a predetermined multiple of the pile bearing capacity (i.e. the bearing capacity increased with a chosen safety coefficient). 5. The steel elements are filled up with concrete. 6. The pile is placed under the desired preloading. Completed Mega pile Fields of application • Can be installed in areas inaccessible to the more classic piling techniques and equipment. • Unlike the classical underpinning method, a pile foundation is realised. • Most commonly used in underpinning of existing structures or reinforcing of existing foundations. • The workspace must be located above the groundwater level. • Simple equipment, no rig is needed.
