Based on the engineering practice,the paper compares and analyzes the process of the water operation platform for pier construction,and introduces the process characteristics,principles,flow and operation points of the precision rolled rolling threaded hanging bottom platform.Combined with the structural characteristics of the fully straight pile,the design of the connection between the pile foundation and the upper structure is innovated.Four fan-shaped steel plates are installed on outer side of the steel pipe piles and welded into circular shape,forming a new type of composite support structure together with the precision rolled threaded hanging bottom and bottom mold,accelerates the project progress,ensures the safety and quality of the construction of large volume high pile piers and technical benefits.This can provide reference for similar pier and abutment construction,as well as the design of connection methods between steel pipe piles and upper structures.
