Installation method of thin film type enclosure system for low-temperature liquid cargo storage and transportation

The invention relates to an installation method of a thin film type enclosure system for low-temperature liquid cargo storage and transportation, which comprises the following steps of: installing secondary insulation modules on a ship body structure by matching first anchoring parts with first pressing blocks, and paving and bonding flexible secondary screen walls along gaps between the adjacent secondary insulation modules after internal thread blind holes of the first pressing blocks are temporarily plugged; the position, corresponding to the internal thread blind hole, of the flexible secondary screen wall is cut off, a temporary plug at the internal thread blind hole is removed, then a second anchoring part is arranged in a penetrating mode to be matched with a second pressing block to fix the main layer insulation module, and finally a third anchoring part is provided with a fastening clamping plate to be in lap joint in a lap joint groove in the edge of the main layer insulation module. The secondary l
