The Press-in Method has variety of superiorities, but had one weakness. It was to press-in at hard ground conditions. It has been a long time pending issue in the Press-in Industry. By the standard press-in method and the press-in with water jetting method cannot enable to install sheet piles into hard ground stratum such as sandy gravel layer with boulders and rock layer.
Super Crush Piler was designed for the solutions such issue. By the realisation of a GIKEN’s unique concept, “the Coring Theory”, which is press-in with simultaneous augering, made sheet piling work possible at hard ground conditions. It dramatically expands the sheet piling range without vitiating the superiorities of the Press-in Method.
