Foundation pile for load transmission - is cast in situ around vertical rods with transverse extensions (BE270976)
Реферат: The pile has a body of at least 1m in length, with several rod extensions (24, 28) of smaller cross-section than the pile. The upper ends of the rods are embedded into the pile body, which is cast in-situ. The rods are distributed over the circumference and the height of the pile. The upper rod ends are connected. The pile body is surrounded by a sleeve of cast or granular material or a free space. The pile is brought into position by partly driving the rod extensions through the walls of the bore into the surrounding ground. The free rod ends in the bore are then connected to the pile body.
