The invention provides a modular arc steel die for half pile construction of a cast-in-place pile and a construction method. The modular arc steel die is formed in a way that a plurality of standard units are spliced, the modular arc steel die is installed in an empty pile area which corresponds to a half pipe, the standard units comprise shells, the interiors of the shells are hollow, the shellsare enclosed by flat plates and curved plates, both ends of the flat plates are respectively connected with both ends of the curved plates, and the space in which the shells are located is the empty pile area. The modular arc steel die is used for forming a standard member for prefabrication, and the assembly is performed in the half pile construction process of the cast-in-place pile, so that modular conditions are obtained. The modular arc steel die can adapt to half pile construction of different heights and different diameters under construction, the application range is wide, and additionally, the modular arc ste
