The foundation pit air dome utilizes an air supply system to raise the indoor air pressure to a certain level, creating a pressure differential between the interior and exterior of the roof. This pressure differential enables the structure to resist external forces and prevents collapse. As a building structural system, it is supported entirely by air pressure. The interior features no column or post obstructions, offering a large, practical space.

The foundation pit air dome is a green construction technique that integrates dust control, noise reduction, energy efficiency, fire resistance, and intelligent monitoring. It demonstrates strong exemplary significance and promotional value, enhancing environmental protection while creating a comfortable working environment on the construction site.
