The invention belongs to the technical field of
bridge engineering, and particularly relates to a construction method of a
pier column external wrapping weather-proof steel plate with a section beinga straight line and circular curve combination. The problems that after an existing
pier column is constructed, a
scaffold is erected on site so as to carry out weather-proof steel plate
assembly andwelding, construction difficulty is large, risks are high, quality is not easily ensured, meanwhile, during steel plate
welding work, the burning damage to the concrete is large, and the quality of the poured
pier column concrete is seriously affected are solved. The method is easy and convenient to operate, rapid and stable, work is convenient and safe, the problems that after the existing pier column is constructed, the
scaffold is erected on site so as to carry out weather-proof steel plate
assembly and
welding, construction difficulty is large, risks are high, quality is not easily ensured, a weather-proof steel plate and pier column are not tight, meanwhile, during steel plate
welding work, the burning damage to the concrete is large, and the quality of the poured pier column concreteis seriously affected are solved, the application range is wide, and certain application and popularization value is achieved.
