Abstract: A head module for a large-scale container, a large-scale container having the head module, and methods for manufacturing the head module and the large-scale container. The method for manufacturing a head module comprises providing a head having an annular opening, the head being composed of a plurality of petals, providing a plurality of cylinder plates, and forming a head cylindrical ring, connecting in order the plurality of cylinder plates to the end surface of the annular opening and joining facing sides of all adjacent cylinder plates. Based on the unfitness of the petals at the annular opening of the head, gaps between adjacent cylinder plates may be adjusted, and/or the positions of the cylinder plates on the end surface of the annular opening of the head may be adjusted radially inwards or outwards.
