The invention relates to a bridge
pile foundation construction method and a guide
pipe auxiliary device thereof, the guide
pipe auxiliary device comprises a supporting table and a clamping mechanism,the supporting table comprises a first supporting table body and a second supporting table body, the clamping mechanism comprises a first clamping plate, a second clamping plate, a driving part and aclamping
assembly, the first clamping plate and the second clamping plate slide on the first supporting table body and the second supporting table body respectively, the driving part is arranged on the first supporting table body and the second supporting table body and used for driving the first clamping plate and the second clamping plate to slide, the clamping
assembly comprises a first flangeplate, a second
flange plate, a first clamping rod and a second clamping rod, the first
flange plate and the second
flange plate are fixed to the two ends of a guide
pipe correspondingly, the first clamping rod and the second clamping rod are both arranged on the second flange plate and can penetrate into the first flange plate, and a locking part used for locking the first clamping rod and the second clamping rod is arranged in the first flange plate. According to the bridge
pile foundation construction method and the guide pipe auxiliary device thereof, when two guide pipes are connected, excessive manpower is not needed for participation, so that the labor capacity of workers is reduced.
