STEEL PIPE PILE COLUMN CONSTRUCTION METHOD

PURPOSE:To make it possible to construct a steel pile column without a hitch even in such a place as space upward of a column construction site is limited, to make it possible to construct the steel pipe pile column having high strength and, at the same time, to execute cut-off treatment to enable the construction of a cut-off retaining wall or a revetment. CONSTITUTION:Wide flange shape steels 6 forming joint spaces 5 are fixed to the insides of steel pipes and, at the same time, steel pipe piles 3 formed of slits 7 to be formed are used, and the force-fit of the steel pipe piles 3 is made up to specific depth at proper intervals. Between adjacent steel pipe piles 3, the force-fit of wide flange shape steels 4 is made up to required depth so that flange sections on both sides of each of the wide flange shape steels are fitted to the insides of the joint spaces 5 of the steel pipe piles 3 on both sides through the slits 7. According to the constitution, intermediate sections of the steel pipe piles 3 are held, and a revolving force-fit type low space pile driver is utilized to execute the force-fit work of steel pipe piles.
