Formwork erecting method for bridge construction

The invention discloses a formwork erecting method for bridge construction, and belongs to the field of bridge construction equipment. A formwork erecting method for bridge construction comprises the following steps that firstly, construction equipment is moved to a bridge pier formwork erecting working area, and the construction equipment is fixed; through flowing of lubricating oil in the injection box, the lubricating oil is injected into the guide ring through the oil injection hole, meanwhile, due to rotation of the guide ring, the guide ring can evenly smear the lubricating oil on the outer surface of the steel cable, and in the process, through arrangement of an elastic filter screen, the lubricating oil can be evenly smeared on the outer surface of the steel cable. Dust and other impurities attached to the outer surface of the steel cable can be scraped off, dust and other impurities attached to the outer surface of the steel cable can be effectively cleared away, gaps between the steel cables formed
