The invention discloses a construction process of a site pre-assembling and integrated driving of a large cylindrical secondary cell of a cellular steel sheet pile. The process comprises the following steps: arranging a corresponding secondary cell assembling bracket at a construction site; directly pre-assembling the cellular steel sheet pile to form the large cylindrical secondary cell on the assembling bracket; directly distributing a plurality of vibration hammers through a floating crane for vibration sinking to hoist the assembled secondary cell from the assembling bracket and then insert into a locking port of a connecting pile of a main cell and the secondary cell at a cylinder position; starting the vibration hammers at the same time to perform vibration sinking for the secondary cell steel sheet pile; operating single hammer by groups to perform vibration sinking in place in case of insufficient overall vibration sinking. With the adoption of the process, the problems of the prior ...
