Gas film for foundation pit and mounting method of gas film

Abstract

The invention discloses an air film for a foundation pit and a mounting method of the air film, and belongs to the technical field of building construction. According to the gas film for the foundation pit and the mounting method of the gas film, the combined frames are connected together through the lock catch assemblies, then the gas film structure is laid above the combined frames for staged mounting operation, and in the mounting process, the locking assemblies and the lock catch assemblies are locked, so that the gas film structure and the combined frames can be connected, and inflation operation is conducted after connection; the air film structure is expanded through the combined frame, then the combined frame is vacuumized through the vacuum assembly, the combined soft sheets are tightly attached, frictional resistance is increased, the combined frame can be hardened, the stable supporting operation on the air film structure can be improved, the combined frame is combined to form a plurality of triangular structures, and the supporting effect can be further enhanced. The flexible structure is adopted before installation, on-site construction is facilitated, the construction difficulty is reduced, the construction period is shortened, the flexible structure can be stored in the later period and is convenient to disassemble, and the operation and maintenance cost is reduced.
