Description

Construction device for rotary digging pore-forming ultra-long permanent steel pile casing filling pile Technical Field The utility model relates to the field of bridge engineering construction, in particular to a construction device for a rotary-digging pore-forming ultra-long permanent steel casing cast-in-place pile. Background The steel pile casing is a temporary structure in pile foundation construction, can effectively protect the pile foundation so as to avoid dangerous conditions such as hole collapse and the like in the construction process, and has important supporting effects on improving the shock resistance and keeping the whole safety and stability of the bridge pile foundation. In most bridge pile foundation construction processes, steel casings are not typically used as stress members, but are removed after the pile foundation is completed.
