Abstract

A pile cage ( 2 ) has a reinforcement structure ( 4 ) having a first part ( 8 ) adapted to remain in a pile, the first part terminating at a predefined cut-off level ( 20 ), and a second part ( 10 ) that is protected in order to debond it from concrete cast around it. A split-wailed annular tube ( 30 ) is located at the cut-off level ( 20 ) and is connected to a supply of pressurised fluid after the concrete has been poured and set. The tube ( 30 ) expands under pressure initiating a crack that is propagated by the escape of fluid from the slit ( 32 ) towards a centre of the pile at the cut-off level ( 20 ). The entire cracked central surface of the cast pile acts as a hydraulic jack separating the pile cap ( 104 ) from the remainder of the pile ( 102 ).
