The embodiment of the invention provides an installation method of a dihedral corner area arrangement structure of a film type enclosure system, and the film type enclosure system comprises a main film layer, a fastening clamping plate, a main insulating layer, a secondary film layer and a secondary insulating layer which are sequentially connected and fixed to a ship body structure through penetrating fasteners. The main thin film layer, the main insulating layer, the secondary thin film layer and the secondary insulating layer define a low-temperature liquid cargo storage tank for accommodating an ultralow-temperature medium, and the main thin film layer is in contact with the ultralow-temperature medium; a corner area where two side faces of the thin film type enclosure system are connected comprises a main layer dihedral corner area and a secondary layer dihedral corner area. The mounting method comprises the following steps of: mounting a distance plate and studs for positioning a dihedral corner area plane transition secondary insulation module of a secondary-layer dihedral corner area and the distance plate of the dihedral corner area secondary insulation module on a cabin wall of a ship body structure according to a set lineation; and then a dihedral corner area plane transition secondary insulation module, a dihedral corner area secondary insulation module and other modules are installed.
